However, when different processes of processing the same workpiece are carried out, a plurality of machine tools are adopted for order-changing processing, the order-changing distance of the upper process and the lower process is long, the time is long, the processing efficiency is low, and the product precision is not high due to the fact that materials are clamped for multiple times. In addition, for some precise parts, the function of automatically identifying or distinguishing the designated machined end face in the automatic feeding process or reversing randomly arranged materials to the designated machined end face in the automatic feeding process cannot be realized, and the automation degree is not high.

In addition, the automatic feeding device is also provided with a material reversing, conveying and guiding function, materials with different shapes and structures at multiple ends or materials with one end being processed in a designated processing process are automatically reversed, and compared with feeding devices only provided with a conveying function, the automatic feeding device is wider in application range. In addition, automatic feeding device still is equipped with the feeding mechanism who is used for connecting the feed mechanism discharge gate, therefore this feeding mechanism has the function of connecting the discharge gate material and deriving the material accuracy, and not only through directly deriving the material behind feed mechanism's transmission and the switching. If only a feeding mechanism is arranged, the reversed material is directly guided to the clamp or the processing device, and in the feeding and processing processes, the phenomena of material accumulation, material blockage and the like in the clamp or the processing device are easily caused due to the fact that the feeding speed is too high, or the phenomena of material shortage and the like occur due to the fact that the processing efficiency of the processing device is too high and the feeding speed cannot follow up, so that the two are difficult to coordinate. Therefore, the feeding mechanism is arranged, so that the materials are accurately connected and transmitted and positioned to the clamp or the processing device, the feeding accuracy is improved, the function of controlling the feeding speed of the materials is achieved, and the materials are prevented from being accumulated or in shortage in the feeding process. In addition, the feeding mechanism and the feeding mechanism transmit materials through a guiding component, one end of the guiding component is connected with the feeding mechanism, and the other end of the guiding component is connected with the feeding mechanism.

The automatic production equipment for the precise part disclosed by the invention is provided with the clamping device, the clamping device is provided with the chuck for clamping materials, the chuck comprises the first clamping component and the second clamping component, the first clamping component and the second clamping component are arranged at intervals to form the first groove cut, two sides of the first groove cut are planes, when a turning tool turns materials with deeper depth, the turning tool can partially or completely enter the first groove cut, the materials are completely cut, the sufficient cutting depth can be met, and the materials do not collide with the clamping part or the chuck. Wherein, the lower terminal surface that sticiss piece one is equipped with part convex bulge one, and two up ends of sticising piece are equipped with part convex bulge two, and bulge one and the setting of bulge two intervals form groove incision two, and bulge one has increased the area of contact of groove incision two with the material with setting up of bulge two, and it is bigger to make the tight dynamics of clamp, avoids or compensaties that the width of groove incision one is great, and makes the clamp force not enough, makes the material location not accurate. Therefore, the sufficient clamping force is guaranteed, and the sufficient cutting depth can be met under the condition of small turning allowance.

According to the automatic production equipment for the precise parts, the sliding table device is arranged, and the sliding assembly which can move in the reciprocating axial direction and/or the reciprocating radial direction is arranged on the clamping device, so that the sliding assembly can drive devices such as a clamp or a cutter to move in multiple directions or multiple directions simultaneously, the convenience and the flexibility of the device are improved, the repeated arrangement of some equipment is reduced, and the structure is simpler. Compared with the existing sliding table devices which only move in a single direction, the sliding table device has a single moving direction, only drives the clamp or the cutter to move in a single direction, and is not suitable for operation with a plurality of processing stations or a plurality of working procedures. Specifically, the sliding assembly is provided with a first guide rail and a second guide rail, the second guide rail is arranged on the lower portion of the first guide rail and fixedly connected with the rack, the first guide rail and the second guide rail are of two relatively independent structures, the first guide rail can move in a reciprocating axial direction, the second guide rail can move in a reciprocating radial direction and can also move in a multi-direction simultaneously, and instructions of an external controller are set according to the requirements of actual clamping or material processing, so that the sliding assembly is controlled. Furthermore, the upper part of the sliding assembly is also provided with a clamping device for clamping materials, particularly for some precise and tiny materials, the sliding assembly is small in size and inconvenient to clamp, precision deviation is easy to exist when clamping and positioning are conducted, subsequent machining precision is poor, in addition, the materials can be clamped and damaged by clamping the materials for many times, clamping times of the clamps to the materials need to be reduced as far as possible, on one hand, the working efficiency can be improved, on the other hand, corresponding machining is completed through one-time clamping and positioning, and the positioning precision is higher.

The automatic production equipment for the precise parts, disclosed by the invention, is provided with the multi-station processing device, and the processing mechanism of the multi-station processing device is provided with a plurality of processing stations with different turning functions, namely, the processing of a plurality of procedures is completed on the same equipment, the operation of a plurality of different procedures can be completed only by clamping the clamp once, and the processing precision is higher. In addition, the processing of a plurality of processes is finished on the same equipment, the assembly line operation or machine adjustment of a plurality of devices is not needed, the labor cost is greatly saved, and the working efficiency is improved. Compared with some machining equipment on the market, in the machining process, if a plurality of equipment assembly line operations are adopted, and a plurality of procedures are used for sequence conversion machining, the deviation of the cutter and program setting among different equipment is caused, the working efficiency is low, more manpower is needed, and the comprehensive cost is higher.

As shown in fig. 1 and 2, as an embodiment of the present invention, an automatic manufacturing apparatus for precision part processing is disclosed, which can be independently manufactured and processed, and can be mounted on or detachably connected to a machine tool or an automatic mechanical apparatus. The invention can be used for processing precise and tiny mechanical components, and the size of the invention can be changed according to the size of different materials so as to be suitable for processing more materials. In this embodiment, an entero/gastroscopic clamp member for use in the manufacture of medical devices, as shown in figure 1.

This automatic production equipment includes automatic feeding device 5 for the material is carried and/or is used for the leading-in feed mechanism 51 of material switching-over transmission, therefore this feed mechanism 51 has the function of automatic conveying material, and the material is arranged at random and is pursued the preface to the discharge gate, need not artifical material loading, has saved the human cost greatly. In addition, for some materials needing to be processed with a specified end face, the function of only conveying the materials cannot be realized, and a manual material reversing procedure needs to be added or equipment or a device with a reversing function needs to be additionally arranged. Especially for some precise and tiny materials, an operator cannot conveniently hold the materials, the end face of the material is identified, and the reversing process is easily influenced by subjective consciousness, so that the manual material reversing work efficiency is low, the error rate is high, and the material reversing machine is not suitable for reversing precise parts. For this reason, the feeding mechanism 51 also has a function of adjusting the end portions of the materials conveyed to the discharging end to the same direction, automatically recognizing or distinguishing a designated processing surface of the materials, and reversing the randomly arranged materials to the designated processing end surface. Therefore, the feeding mechanism 51 can not only automatically convey materials, but also automatically reverse the materials without manual operation, and is high in conveying efficiency and accurate in reversing.

The automatic feeding device 5 is provided with a feeding mechanism 52 for connecting the discharge port 511 of the feeding mechanism 51, so that the feeding mechanism 52 has the function of connecting the material at the discharge port 511 and accurately discharging the material, rather than directly discharging the material only by the transmission and reversing of the feeding mechanism 51. If only the feeding mechanism 51 is arranged, the reversed material is directly led out to the clamp or the processing device, and during the feeding and processing, the phenomena of material accumulation, material blockage and the like in the clamp or the processing device are easily caused due to the excessively high feeding speed, or the phenomena of material shortage and the like are caused due to the excessively high processing efficiency of the processing device and the lack of the feeding speed, so that the two are difficult to coordinate. Therefore, the feeding mechanism 52 is arranged, so that materials are accurately connected, conveyed and positioned to the clamp or the processing device, the feeding accuracy is improved, the function of controlling the feeding speed of the materials is achieved, and the materials are prevented from being accumulated or in shortage in the feeding process.

Meanwhile, the feeding mechanism 51 is provided with a leading-in member 53 for transmitting the material to the feeding mechanism 52, and one end of the leading-in member 53 is connected with the feeding mechanism 51, and the other end is connected with the feeding mechanism 52. Feed mechanism 51 is connected through leading-in component 53 with feed mechanism 52 is direct, has not only realized material transmission's function, does not be equipped with other external connecting pieces moreover, simple structure, and material transmission is swift accurate, compares in some loading attachment on the market, connects the material through manipulator or other rotation piece, and the structure is complicated, and the material loading error appears in material handling or transmission course easily. Of course, in other embodiments, the introducing member 53 may be another connecting member having a function of connecting the feeding mechanism 51 and the feeding mechanism 52.

As shown in fig. 3, the automatic production apparatus includes a clamping device 1 including a chuck 13 for clamping the material, the chuck 13 is provided with at least one set of a first clamping assembly 11 and a second clamping assembly 12, in this embodiment, a set of the first clamping assembly 11 and a set of the second clamping assembly 12, and in other embodiments, a plurality of first clamping assemblies 11 and/or second clamping assemblies 12 may be provided to form a plurality of clamping portions or chucks 13. The first clamping assembly 11 and the second clamping assembly 12 are provided with one or more first pressing blocks 112 and second pressing blocks 113, and the two pressing blocks are structurally the same, so that under the same applied force, the clamping force of the two pressing blocks is consistent, the clamping force is not different due to inconsistent structures of the first clamping assembly 11 or the second clamping assembly 12, and the material is not accurately positioned or damaged due to overlarge clamping force. In this embodiment, one compressing block 112 and one compressing block 113 are provided, and in other embodiments, a plurality of compressing blocks 112 and/or two compressing blocks 113 may be provided, which also have the above-mentioned functions and can make the clamping force of the clamping device larger.

As shown in fig. 4, in some embodiments, the first clamping assembly 11 and the second clamping assembly 12 are arranged in radial symmetry at the position of the chuck 13, the material is clamped between the two clamping assemblies, so that the clamping force on the two sides is more uniform, in addition, the first clamping assembly 11 and the second clamping assembly 12 are provided with a first groove cut 14 at intervals, the two sides of the first groove cut 14 are planes, when the turning tool turns the material with the deeper depth, the turning tool can partially or completely enter the first groove cut 14, the material is completely cut, the sufficient cutting depth can be met, and the material does not collide with the clamping portion or the chuck 1. Specifically, the first pressing block 112 and the second pressing block 113 are axially symmetrically arranged, and are radially symmetrically arranged with the first clamping assembly 11 and the second clamping assembly 12 to form a cross-shaped structure, so that a better stabilizing effect is achieved. The lower end face of the first pressing block 112 is provided with a first protruding part 1121, the upper end face of the second pressing block 113 is provided with a second protruding part 1122, and the first protruding part 1121 and the second protruding part 1122 are arranged at intervals to form a second groove notch 15. Specifically, the first protrusion 1121 and the second protrusion 1122 are adjacent to the end face for clamping the material, so that the contact area between the second groove notch 15 and the material is increased, the clamping force is larger, the situation that the width of the first groove notch 14 is large or is compensated for, the clamping force is insufficient, and the material is not accurately positioned is avoided. Therefore, enough clamping force is guaranteed, and enough cutting depth can be met under the condition of smaller turning allowance.

As shown in fig. 5, the automatic production equipment comprises a sliding table device 2 connected with a frame 7 and including a sliding assembly 23 which can move in a reciprocating axial direction and/or a reciprocating radial direction, so that the sliding assembly 23 can drive devices such as a clamp or a cutter to move in multiple directions or multiple directions simultaneously, the convenience and flexibility of the device are improved, the repeated arrangement of some devices is reduced, and the structure is simpler. Compared with the existing sliding table devices which only move in a single direction, the sliding table device has a single moving direction, only drives the clamp or the cutter to move in a single direction, and is not suitable for operation with a plurality of processing stations or a plurality of working procedures. Specifically, the sliding assembly is provided with a first guide rail 21 and a second guide rail 22, the second guide rail 22 is arranged on the lower portion of the first guide rail 21 and fixedly connected with the rack 7, the first guide rail 21 and the second guide rail 22 are of two relatively independent structures, the first guide rail 21 can axially move in a reciprocating mode, the second guide rail 22 can radially move in a reciprocating mode, and can also move in multiple directions simultaneously, instructions of an external controller are set according to the requirements of actual clamping or material processing, and then the sliding assembly is controlled.

Furthermore, the upper part of the sliding component 23 is also provided with a clamping device 1 for clamping materials. For some precise and tiny materials, the material clamping device is small in size, inconvenient to clamp, prone to accuracy deviation when clamping and positioning, poor in subsequent machining accuracy, and capable of clamping materials for multiple times, clamping times of the material by the clamp are required to be reduced as far as possible, on one hand, work efficiency can be improved, and on the other hand, corresponding machining is completed through one-time clamping and positioning, so that the positioning accuracy is higher.

As shown in fig. 6, the automatic production equipment includes a multi-station processing device 8 connected to the frame 7, and includes a processing mechanism 81 for turning the material, in this embodiment, a worktable 83 for placing the processing mechanism is provided on the frame 7, and the worktable 83 is connected to the frame 7. Therefore, in the material processing process, the worktable 83 and the processing mechanism 81 are both in a static and passive state, and the material needs to be actively operated and fed to the processing mechanism 81 through a clamping device or a mechanical arm so as to complete processing and turning, so that the structure is simple and the product precision is high. Especially for some precise and tiny components, the processing precision requirement is high, and the process is complex. Compared with some machining equipment on the market, in the machining process, if a plurality of equipment assembly line operations are adopted, and a plurality of procedures are used for sequence conversion machining, the deviation of the cutter and program setting among different equipment is caused, the working efficiency is low, more manpower is needed, and the comprehensive cost is higher. If single-station equipment is adopted, and each procedure is completed on the equipment, the operation of each procedure needs to be adjusted and clamped again, so that the fixture is clamped and repeatedly positioned for multiple times, the size yield is low, the final finished product precision is low, and the working efficiency is low. In addition, although a plurality of machining stations are arranged, the multi-station automatic turning machine is actively operated, the sliding table is arranged on each station to move, and materials fixed on the clamping device are turned, so that the machining efficiency is improved, multiple clamping and positioning are not needed, and the product precision is improved. However, such multi-station equipment is complex in structure, needs to be provided with a plurality of sliding tables to drive a plurality of processing stations to move, and is not high in multi-direction moving and positioning accuracy.

The machining mechanism 81 in this embodiment is provided with a plurality of machining stations 82 having different turning functions, and the plurality of machining stations 82 are connected in series to a table 83. The machining of a plurality of processes is completed on the same equipment, the operation of a plurality of different processes can be completed only by clamping the clamp once, and the machining precision is high. In addition, the processing of a plurality of processes is finished on the same equipment, the assembly line operation or machine adjustment of a plurality of devices is not needed, the labor cost is greatly saved, and the working efficiency is improved.

In other embodiments, as shown in fig. 7, the feed mechanism 51 includes a diverter assembly 54 that can direct material into the intake member 53 in the same direction. The reversing assembly 54 can automatically reverse the materials without manual operation, and is high in machining efficiency and reversing accuracy. In the embodiment, the reversing component 54 reverses the materials at the discharging hole 511, so that the materials passing through the discharging hole 511 are all reversed by the reversing component 54, and the error-proofing function is achieved. More importantly, the reversing assembly 54 directly transmits the reversed materials to the guide-in member 53, and the feeding and reversing are synchronously performed without transmission and transfer of other connecting pieces, so that the reversing function in the feeding is realized, the time is effectively saved, and the efficiency is improved. Compare in other some switching-over devices on the existing market, it sets up the switching-over part in the course of working, directly drives the material through rotating parts such as being equipped with pivot or swing arm and processes to the station. Although the material reversing function can be realized, the materials are reversed end by end and then processed end by end in the processing process, most of the materials can only be operated on a single material, the processing efficiency is low, and in addition, the positioning accuracy of the materials in the clamping process is not high after the materials rotate for many times.

Specifically, the feeding mechanism 51 is further provided with a vibrating disk 512 for orderly arranging and conveying the materials contained in the feeding mechanism to the discharge hole 511, the inner wall of the vibrating disk 512 is a spiral track 5121 which gradually spirals up, the spiral track 5121 gradually ascends and narrows, and the spiral track 5121 finally ascends to the discharge hole 511. Specifically, the material is vibrated by the bottom of the vibrating plate 512 to ascend along the spiral track 5121, and during the ascending process, along with the narrowing of the spiral track 5121 and the screening of a series of tracks, a part of the material falls to the bottom and is vibrated again to ascend along the spiral track 5121, and the ascending material finally reaches the discharge end in a single row and single column manner. Therefore, the disordered materials are automatically, orderly and accurately conveyed, and the single materials are gradually output, so that the orderly material reversing of the feeding mechanism 51 is facilitated. The vibration plate 512 is further provided with a vibration controller 5122 for controlling the on/off, adjusting the vibration frequency, and the like. In addition, the reversing assembly 54 is arranged at the upper edge of the vibrating disk 512, specifically on the outer wall surface of the vibrating disk 512 opposite to the discharge port 511, and is adjacent to the discharge port 511 at a certain interval, and the distance between the two parts is short, which is beneficial to the close connection of the discharge and the reversing of the materials, and the efficiency is higher. In other embodiments, if the reversing assembly 54 is far from the discharge port 511 and is disposed on other end surfaces of the vibrating plate 512 or other devices, the reversing of the material may also be performed, but a connecting member or a transmission member is also required to connect the two, which makes the structure more complicated and the efficiency lower. In other embodiments, the feeding mechanism 51 may also be a pneumatic feeder, an electric vacuum feeder, or other devices with a feeding function.

As shown in fig. 8, the material in this embodiment is a cylindrical material 3 with two different structures at two ends, specifically, one end of the cylindrical material 3 is provided with a recess 31, and a small hole 32 is provided in the middle, and the other end is a closed plane end 33. In other embodiments, the cylindrical material 3 may be other materials with different configurations or shapes at multiple ends, and the above-mentioned effects are also achieved. Further, as shown in fig. 9, the finished cylindrical material 3 4 in this embodiment is provided with a middle notch 41, a smooth fillet 411 is provided on the peripheral surface of the notch, and channels 42 are further provided on the end surfaces of the other two sides, and the channels 42 are disposed on the two opposite sides and are a first channel 421 and a second channel 422.

As shown in fig. 10, the introducing member 53 may contain a plurality of materials therein, and has a discharging passage 531 therein for transferring the materials diverted by the diverting assembly 54. In this embodiment, the discharging channel 531 is a pipe-shaped hollow structure with a width slightly wider than the diameter of the material, so that the material is transported in a single row and single column to ensure the consistency of the discharging speed and the discharging amount of the vibrating disk 512, and prevent the phenomenon of excessive material accumulation or material vacancy. Specifically, in addition, the feeding mechanism 52 is provided with a positioning assembly 55 for acquiring the material at one end of the blanking channel 531 and guiding the material out, the positioning assembly 55 is fixed on the frame 7, the discharging end 5312 of the blanking channel 531 is connected with the positioning assembly 55, and the ground is used as a reference surface, the height of the feeding end 5311 of the blanking channel 531 is higher than that of the discharging end 5312, so that the material automatically slides downwards to the discharging end 5312 according to the gravity center, and the blanking channel 521 is an inclined channel inclined towards the positioning assembly 55. In other embodiments, the feeding channel 531 may be two or more than two or be widened in width to accommodate multiple rows and multiple columns of materials, which all have the above-mentioned functions and the conveying efficiency is higher.

In other embodiments, as shown in fig. 11, the reversing assembly 54 includes a guide 541 for identifying at least one end face of the material facing, the guide 541 is disposed on the reversing assembly 54 and is vertically long, and the guide 541 is disposed at the front of the outlet 511, and has a lower end height substantially flush with the material in the outlet 511, and the guide 541 is not or partially in contact with the end face of the outlet 511 during the material reversing process. Specifically, in the discharging process, the materials are individually discharged to the discharging port 511 until any end surface of the materials contacts with the guide 541, and the materials push the guide 541 at the front part outwards under the action of force. The reversing assembly 54 further includes a bracket for mounting the guide member 541, wherein the upper end of the guide member 541 is rotatably connected to the bracket 542 and can swing within a certain range. The lower end of the guiding element 541 is provided with a bending part 5413 which can partially or completely extend into the concave part 31 or the small hole 32 of the cylindrical material 3, and the bending part 5413 and the guiding element 541 are bent towards the discharging hole 511 at an angle slightly larger than 90 degrees. During the discharging process, the cylindrical material 3 pushes out the bending portion 5413 of the guide 541, and the end of the recess 31 faces the bending portion 5413, the bending portion 5413 can catch the recess 31 when the cylindrical material 3 falls, so that the flat end 33 inclines downward and slides down to the feeding end 5311 of the discharging channel 531, thereby completing the reversing. However, if the flat end 33 faces the bending portion 5413, the bending portion 5413 cannot catch the cylindrical material 3, and the cylindrical material 3 falls into the vibration tray 512, and the direction change and the transportation cannot be completed. In addition, if the feed member 53 is filled with the material, the material overflows from the opening of the feed end 5311, and even if the end of the concave portion 31 faces the bent portion 5413, the flat end 33 collides with the cylindrical material 3 at the opening of the feed end 5311 in the process of being inclined downward, and thus falls into the vibration plate 512. Therefore, the reversing and conveying can be completed only when the guiding member 53 is not full and the end of the concave portion 31 of the cylindrical material 3 faces the bending portion 5413 during discharging, and the functions of automatically recognizing the end surface of the cylindrical material 3 and uniformly reversing the random two end surfaces of the cylindrical material 3 to the flat end 33 are provided.

As shown in fig. 12, the positioning assembly 55 is provided with a movable plate 551 moving to and fro and a connecting member 552 for getting the material to the movable plate 551. The connecting member 552 is connected to a discharge end 5311 of the discharging passage 531, and discharges the material onto the connecting member 552. Further, the other end of the connecting member 552 is communicated with the movable plate 551, the movable plate 551 guides the cylindrical material 3 in the connecting member 552 through an ascending motion, and the material is directionally moved to a certain position through a descending motion and a part of the material is guided out, so that a subsequent clamp or a subsequent processing device is convenient to clamp and position more accurately. In this embodiment, the movable plate 551 only picks up one material per reciprocation from the connecting member 552 to further control the discharge speed and coordinate with the processing speed. In other embodiments, a plurality of movable plates 551 may be provided, or a plurality of materials may be obtained from the connecting member 552, which all have the above-mentioned functions and improve the processing efficiency.

In some embodiments, the width of the first flute cut 14 is greater than that of the second flute cut 15, and the first flute cut 14 has a function of positioning materials due to the greater width, and most importantly, a part or all of the turning tool can enter the first flute cut 14 to cut deep materials. The width of the second groove cut 15 is narrower than that of the first groove cut 14, so that the clamping force is increased, the materials are not easy to loosen, and clamping is more accurate. In other embodiments, the width of the second slot 15 may be greater than or equal to the width of the first slot 13, and the second slot also has a function of clamping and positioning, and is only deficient in clamping force. In addition, the protruding cross-sectional shapes of the first protruding portion 1121 and the second protruding portion 1122 are rectangular, so in other embodiments, a part or all of the cutters can enter the second groove cut 15 to cut deep parts of the material.

Therefore, the slide plate 211 not only has the function of connecting the slide base 213, but also has the function of supporting the slide base 213 and the holding device 1, and the structure is simple and the effect is diversified. If the slide 211 is not provided, but the slide 213 is directly connected to the first rail 21, the pressure on the first rail 21 is large, and the structure is thin and easy to damage. In addition, the lower end surface of the sliding plate 211 is fixedly connected with the first guide rail 21, so that the first guide rail 21 can directly drive the sliding plate 211 and the clamping device 1 on the upper part of the sliding plate 211 to translate when translating. In other embodiments, the upper end surface of the first guide rail 21 may also be provided with a plurality of sliding plates 211, which may have a more stable structure, or the upper end of the sliding base 213 may be provided with a sliding plate, which may have a better supporting force.

During the discharging process, the material 3 pushes the bending part 5413 of the guide piece 541 outwards, if one end face of the concave part 31 of the material faces outwards, the bending part 5413 of the leading-in member 53 can hook the concave part 31 when the material falls, so that the other plane end 33 inclines downwards and slides to the blanking channel 531 inside the leading-in member 53, and one end of the material is reversed to the same direction; if the flat end 33 of the material faces outward, the bent portion 5413 of the introducing member 53 cannot take out the material, and the material drops into the vibration tray 512 to be loaded again. The reversed material is transmitted into the connecting member of the positioning assembly 55 through the discharging channel 531, and the other end of the connecting member 552 is communicated with the movable plate 551 which reciprocates up and down, so that the movable plate 551 acquires the material in the connecting member 552 and guides out the material.
