Detailed Description
For the purposes of making the objects, method aspects and advantages of the embodiments of the present invention clear, a method aspect of the embodiments of the present invention will be clearly and completely described, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments.
Embodiment 1 as shown in fig. 1-4, the workpiece detection system based on mechanical movement feedback comprises a bottom plate 1, a detection assembly 2 and a reference positioning seat 3, wherein the detection assembly 2 is in sliding connection with the bottom plate 1 and surrounds the edge of the bottom plate 1, the detection assembly 2 is in abutting joint with the bottom wall or the side wall of an object to be detected, the detection assembly 2 is at least used for detecting flatness, at least two reference positioning seats 3 are symmetrically arranged on two sides of the bottom plate 1, the reference positioning seat 3 comprises a cover plate 31, a positioning sleeve 32, an elastic piece 33 and a limiting sleeve 34, the cover plate 31 is connected with the bottom plate 1, the cover plate 31 and the bottom plate 1 are provided with mutually communicated through holes, the positioning sleeve 32 is arranged between the positioning sleeve 32 and the cover plate 31 in a penetrating mode, the limiting sleeve 34 is sleeved on the positioning sleeve 32, one end, far away from the detection assembly 2, of the positioning sleeve 32 is flush with the surface of the bottom plate 1, and the maximum distance of the positioning sleeve 32 is larger than the maximum distance of a positioning pin 41 of the object to be detected 4.
In the specific implementation process, the gauge is a simple detection tool used for controlling parameters such as the aperture, the space dimension and the like of a product in industrial production, and the core functions of the gauge comprise part profile detection, hole site verification, dimension evaluation and the like. However, the common three-coordinate detection device has extremely high cost, especially the device which can directly obtain the surface structure model of the object to be detected 4 through scanning, and the detection tool with lower cost is difficult to have multiple detection functions at the same time, because mutual interference may occur in the process of implementing detection.
For example, an automotive battery is generally provided with a positioning pin 41, the positioning pin 41 can be matched with a preset hole position of a battery shell or a mounting bracket to limit the movement and the rotation freedom degree of the battery in the axial direction X, Y, Z, and the accurate alignment of the mounting position of the battery is ensured, so that the battery detection process comprises the detection of the positioning pin 41, the detection tool is generally provided with a through hole matched with the positioning pin 41, and if the positioning pin 41 cannot pass through the through hole, the precision of the position or specification of the positioning pin 41 is not satisfied. In the case of detecting the battery of the automobile, if the position or specification of the positioning pin 41 is not satisfactory, the positioning pin 41 interferes with the relative position between the gauge and the object 4 to be detected, so that the detection cannot be realized even if the gauge is provided with the detection device related to the flatness or the profile. Thus, the applicant conceived a workpiece inspection system that can also perform inspection of the flatness of the object 4 to be inspected when the positioning pin 41 is not satisfactory in position or gauge accuracy.
In this embodiment, the reference positioning seats 3 for detecting the positioning pins 41 may be disposed opposite to each other on both sides of the base plate 1, and positioning between the base plate 1 and the object 4 in the X direction and the Y direction, that is, positioning of the relative positions in the horizontal direction is achieved by the two opposite reference positioning seats 3. In this embodiment, the positioning sleeve 32 has a certain degree of movement in the longitudinal direction by the cooperation of the positioning sleeve 32, the limiting sleeve 34 and the elastic member 33, and whether the positioning pin 41 is qualified can be directly determined by the relative positional relationship between the positioning sleeve 32 and the bottom plate 1. When the setting of the positioning pin 41 meets the preset requirement, the positioning pin 41 can be completely contained in the positioning sleeve 32 without contacting with the positioning sleeve 32, and at this time, as shown in fig. 8, the positioning sleeve 32 does not move, the relative position between the positioning sleeve 32 and the bottom plate 1 is unchanged, and the end part of the positioning sleeve 32 is flush with the bottom plate 1. When the setting of the positioning sleeve 32 does not meet the preset requirement, the positioning pin 41 directly contacts with the positioning sleeve 32, and in the process of placing the bottom plate 1, the positioning pin 41 can push the positioning sleeve 32, so that the positioning sleeve 32 moves, and the detection result of the positioning pin 41 can be judged by observing the protrusion of the end part of the positioning sleeve 32 from the surface of the bottom plate 1.
In addition, due to the arrangement of the reference positioning seat 3 in the embodiment, under the condition that the positioning pin 41 is abnormal, the positioning sleeve 32 is movable, that is, the relative position between the positioning pin 41 and the bottom plate 1 can ensure the follow-up detection items, such as the detection of the flatness of the object 4 to be detected, so that the detection process is more convenient.
As shown in fig. 4, the cover plate 31 is circular, and the elastic member 33 is a spring. As shown in fig. 1 and 3, the reference positioning seat 3 may be provided with a housing, and the stop collar 34, the positioning sleeve 32, etc. are disposed in the housing, and then the housing is connected with the bottom plate 1 to realize the installation of the reference positioning seat 3.
The specific device used in the detection assembly 2 may be a conventional device, and may be selected according to the specific detection item of the object 4 to be detected. The purpose of the flatness detection is to detect the deviation between some wall surfaces of the object 4 to be measured and the ideal plane. For example, when the battery is mounted, some of the walls need to abut against other walls to ensure accuracy of the mounting position, such as the flange 42 structure shown in fig. 7. If the levelness deviation appears on the surface of the battery, the battery can be installed in a deviation way, and the use of the battery is further affected.
Embodiment 2 As shown in fig. 5-6, in this embodiment, the detecting assembly 2 includes a flatness detecting member 21, where the flatness detecting member 21 includes a connecting rod 211, a dial indicator 212, an extending member 213, and a rolling member 214, the connecting rod 211 is slidably connected with a side wall of the base plate 1, a measuring rod 2121 of the dial indicator 212 is penetrating through the connecting rod 211, one end of the extending member 213 is connected with one end of the measuring rod 2121 away from the dial plate, the rolling member 214 is connected with the other end of the extending member 213, and the rolling member 214 is used for abutting against a surface of the object 4 to be detected.
In a specific implementation process, the dial indicator 212 for detecting flatness is a prior art, and the principle is that a small linear displacement of the measuring rod 2121 is amplified into a rotary motion of a pointer through a gear transmission or a lever mechanism, so that a displacement amount is read on a dial. In this embodiment, the setting of the connecting rod 211 and the rolling element 214 is provided, the rolling of the rolling element 214 on the surface to be measured is utilized to detect the flatness of the surface to be measured, if the flatness of the surface to be measured is poor, the measuring rod 2121 connected with the connecting rod 211 is displaced, and then the rotation angle of the pointer on the dial is fed back, if the rotation angle is greater than the preset deviation value, the flatness of the surface to be measured is not in compliance with the requirement.
Since the dial plate of the dial indicator 212 and the measuring rod 2121 are conventional, but the length specification is not necessarily applicable to the object 4 to be measured in the present embodiment, the rolling element 214 needs to be contacted with the surface to be measured on the base plate 1 by the design of the length of the connecting rod 211.
For example, the rolling member 214 may employ a roller.
As shown in fig. 2, a sliding rail is disposed on a side wall of the base plate 1, and a slider matched with the sliding rail is disposed on an end of the connecting rod 211, so as to realize sliding connection between the flatness detecting element 21 and the base plate 1. Limiting the moving direction of the flatness detecting piece 21 and the height in the longitudinal direction through the arrangement of the sliding rail, and then in the sliding process, different forces can be transmitted to the measuring rod 2121 according to the difference of the flatness of different sections of the surface to be detected, so that the moving distance of the measuring rod 2121 changes, and the flatness is represented through the size of the pointer rotation angle on the dial plate.
In embodiment 3, as shown in fig. 2 and 5, in this embodiment, a receiving groove 2111 is provided at an end of the connecting rod 211 away from the base plate 1, the receiving groove 2111 is provided with a connecting hole, the measuring rod 2121 of the dial indicator 212 is disposed through the connecting hole, one end of the extending member 213 is connected with the measuring rod 2121, and a gap exists between an end of the extending member 213 away from the rolling member 214 and a groove wall of the receiving groove 2111.
In a specific implementation process, since the movement path of the rolling element 214 needs to be ensured by the connecting rod 211 in this embodiment, the position of the connecting rod 211 in the longitudinal direction is kept fixed, and the extending element 213 is additionally provided as a force transmission medium, so that the rolling process of the rolling element 214 on the surface to be measured can transmit the force to the measuring rod 2121.
Embodiment 4 As shown in fig. 6-7, in this embodiment, the extending member 213 includes a first plate 2131 and a second plate 2132, one end of the first plate 2131 is connected to the measuring rod 2121 of the dial indicator 212, the extending direction of the first plate 2131 is consistent with the extending direction of the connecting rod 211, one end of the second plate 2132 is connected to the first plate 2131, and the other end of the second plate 2132 is connected to the rolling member 214 and extends toward the middle of the base plate 1.
In the implementation process, as shown in fig. 6, the first plate 2131 and the second plate 2132 integrally form an included angle of 90 °. In order to avoid that the connecting rod 211 prevents the gauge from being lowered in the process of placing the gauge in place, a certain gap is usually reserved between the connecting rod 211 and the outer wall surface of the to-be-measured object 4, and in order to ensure that the rolling element 214 can be abutted against the to-be-measured surface, the horizontal position of the rolling element 214 can be far away from the connecting rod 211 through the arrangement of the second plate 2132, and then extends to the to-be-measured surface. The middle of the base plate 1 refers to a central axis of the base plate 1 in the width direction or the length direction.
Embodiment 5 As shown in fig. 2, in this embodiment, the detecting assembly 2 includes a first profile detecting member 22, where the first profile detecting member 22 is slidably connected to the sidewall of the base plate 1, and a detecting surface of the first profile detecting member 22 is adapted to a surface to be detected of an object to be detected.
In the specific implementation process, the principle of contour degree detection is that the measuring method for evaluating the shape accuracy of the surface of the workpiece by comparing the deviation between an ideal contour and an actual contour is mainly divided into two technical routes of contact type and non-contact type. The present embodiment employs the contact principle for detection. The shape of the detection surface on the first profile-degree detecting member 22 is set according to the ideal profile, and the shape of the detection surface may be set with a tolerance, and when the first profile-degree detecting member 22 is slid, if the first profile-degree detecting member 22 cannot pass through smoothly at a certain position, it indicates that the profile degree does not meet the standard. By way of example, the profile of the flange 42 shown in fig. 7 is detected, and after the detection surface of the first profile detecting member 22, which is set in advance according to the desired profile, is placed in place by a structure similar to the connecting rod 211 in the flatness detecting member 21, the first profile detecting member 22 is moved, and at this time, whether the profile of the surface to be detected meets the standard or not can be obtained according to the positional relationship between the detection surface and the surface to be detected.
In embodiment 6, as shown in fig. 2 or 9, the detecting assembly 2 includes second profile detecting members 23, the second profile detecting members 23 are disposed on two sides of the moving path of each of the first profile detecting members 22, the second profile detecting members 23 are connected with the side wall of the base plate 1, the detecting surface of the second profile detecting members 23 is adapted to the surface to be detected of the object to be detected, and when the second profile detecting members 23 are abutted to the object to be detected, the positioning pins 41 on the object to be detected are accommodated in the positioning sleeve 32 or abutted to the end portions of the positioning sleeve 32.
In a specific implementation, the second profile tolerance detection element 23 has at least two functions. The first function is that the end of the second profile tolerance detecting element 23 needs to be abutted against an object to be detected, such as the flanging 42 of a battery, so that the length of the second profile tolerance detecting element 23 can determine the position of the bottom plate 1 in the longitudinal direction, and then the positioning of the bottom plate 1 in the Z direction can be realized through the second profile tolerance detecting element 23, after the second profile tolerance detecting element 23 is matched with the reference positioning seat 3, the space positioning of the bottom plate 1 can be integrally realized, the relative position relationship between the bottom plate 1, the detecting assembly 2 and the object 4 to be detected is ensured, and the accuracy of the detection result of the first profile tolerance detecting element 22 and the flatness detecting element 21 is further ensured. In order to better realize the first function, the present embodiment is thus provided with the second profile-degree detecting members 23 on both sides of the moving path of the first profile-degree detecting member 22, and the moving path of the first profile-degree detecting member 22 is usually determined by a slide rail, whereby the second profile-degree detecting members 23 are provided on both ends of the slide rail. The second function is to realize the profile of the surface of the object to be detected 4 at the two ends of the detectable surface of the first profile detection piece 22 through the detection surface arranged on the second profile detection piece 23 according to the ideal profile, and ensure that the bottom plate 1 does not deviate after the detection surface at the end part of the second profile detection piece 23 is matched with the surface to be detected while realizing comprehensive detection. The detection results of the flatness detecting piece 21 and the first profile detecting piece 22 may not match with the actual condition of the surface to be detected if the base plate 1 is deflected.
Embodiment 7 As shown in fig. 3-4, in this embodiment, the positioning sleeve 32 includes a large-diameter section 321 and a small-diameter section 322 that are mutually communicated, one end of the elastic member 33 is connected with the end wall of the large-diameter section 321, the other end of the elastic member 33 is connected with the cover plate 31, and the small-diameter section 322 is disposed through the through hole.
In particular, fig. 4 conceals the outer housing portion to better illustrate the relationship of the stop collar 34 to the spacer collar 32. The large diameter section 321 has a larger outer diameter than the small diameter section 322. After the positioning sleeve 32 is designed into two sections with different outer diameters, as shown in fig. 3, the spring can be sleeved on the small-diameter section 322, the large-diameter section 321 is used for connecting the top ends of the springs, and the bottom ends of the springs are connected with the cover plate 31.
In embodiment 8, as shown in fig. 3, a stop block 341 is disposed on an inner wall of the stop collar 34, the positioning collar 32 is provided with a stop groove 323 matching with the stop block 341, an end of the stop groove 323 away from the cover plate 31 is an open end, and when an end of the positioning collar 32 away from the detection assembly 2 is level with a surface of the base plate 1, the elastic member 33 is in a compressed state.
In a specific implementation process, the stop block 341 and the limit groove 323 may be annular, and the stop block 341 is accommodated in the limit groove 323. As shown in fig. 3, the top end of the limiting groove 323 in fig. 3 is open, so that the limiting sleeve 34 is convenient to disassemble and assemble, and the positioning sleeve 32 has downward mobility.
For example, as shown in fig. 1, the inspection tool may be taken or placed by the moving device 5, and the moving device 5 may have the movement of the inspection tool in the x, y and z directions by using an existing track system.
Embodiment 9. The present embodiment provides a detection method of the workpiece detection system, including:
S100, moving the bottom plate 1 to enable the detection assembly 2 to be arranged around the object to be detected in a surrounding mode and abutted to the surface to be detected;
S200, acquiring the relative position relation between the end part of the positioning sleeve 32 and the surface of the bottom plate 1;
If the end part of the positioning sleeve 32 is flush with the surface of the bottom plate 1, detecting the flatness and the profile of the surface to be detected through the detection assembly 2, and judging whether the object to be detected is qualified or not according to the detection result;
If the end of the positioning sleeve 32 protrudes from the surface of the bottom plate 1, the object to be detected is judged to be unqualified, and the defect part is judged by the detection assembly 2.
In the specific implementation process, after the workpiece detection system provided in embodiments 1-8 is adopted, even if the positioning pin 41 fails, the subsequent detection of the flatness and the profile tolerance can be continued, so that the detection process is more convenient. In addition, even when the gauge is placed, the protrusion of the end portion of the positioning bush 32 from the surface of the base plate 1 cannot be directly determined as the abnormality of the positioning pin 41, which may be caused by the abnormality of the levelness or the like of the base plate 1 due to the abnormality of the surface structure of the side surface to be detected, and further, the relative position of the positioning pin 41 and the reference positioning seat 3 is abnormal, whereby the flatness detecting element 21, the first profile detecting element 22, and the second profile detecting element 23 are further provided on the same base plate 1 for the purpose of determining specific defective portions for the purpose of checking the pre-process, determining the process causing the abnormality of the workpiece, and then correcting.
Embodiment 10. In this embodiment, the method for judging a defective portion includes:
After the second profile tolerance detection piece 23 is abutted against the object to be detected, the flatness detection piece 21 is slid, flatness information is obtained, and whether the flatness is qualified or not is judged according to the flatness information;
If the flatness is not qualified, the defect part comprises a surface to be detected corresponding to the flatness detecting piece 21;
if the flatness is qualified, the first contour degree detecting piece 22 is slid to judge whether the contour degree of the surface to be detected is qualified, if the contour degree is qualified, the defect part comprises a locating pin 41 of the object to be detected, and if the contour degree is not qualified, the defect part is the corresponding surface to be detected of the first contour degree detecting piece 22 and/or the locating pin 41 of the object to be detected.
In a specific implementation process, the flatness is detected first, and then the contour degree is detected, so that the flatness affects the overall spatial position of the base plate 1 more, and the contour degree is detected by detecting the outer edge wall of the object 4 more, thereby affecting the relative positions of the base plate 1 and the object 4 in the horizontal direction more. When the profile is not qualified, it cannot be directly determined whether the abnormality of the positioning pin 41 is directly caused by the abnormality of the profile, and thus when the profile is not qualified, the defect part has the surface to be detected corresponding to the first profile detecting member 22, and the positioning pin 41 of the object to be detected may be present.
The above is only a preferred embodiment of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
