Description

Chain clamp magazine

The present invention relates to a chain-type clamp library, and more particularly to a chain-type clamp library that can place multiple tools through a clamp chain, and allows the tools to change position as the clamp chain moves, so that the tools can be easily accessed.

For example, Chinese patent publication number CN210703799U "A servo corner tool magazine mechanism" discloses a servo corner tool magazine mechanism, wherein the corner reducer is connected to the output shaft of the servo motor, and the output shaft of the corner reducer is connected to a rotating fixed plate, and the bottom of the rotating fixed plate is fixedly sleeved with a fan-shaped rotating plate, and a plurality of tool holders are installed at the edge of the fan-shaped rotating plate. The servo motor is the power source. The servo motor rotates and increases the torque through the angle reducer to transmit the power to the rotating fixed plate. The rotation angle of the servo motor will be transmitted to the tool holder. The tool holder where the tool handle is to be placed is rotated to the tool change point. After the spindle moves to the tool change point and the tool handle is placed on the tool holder, the servo motor rotates the tool handle to be installed on the spindle to the tool change point through the fan-shaped rotating plate. The spindle grabs the required tool handle to complete the tool change.

However, the above-mentioned previous case is to rotate the tool holder where the tool holder is to be placed to the tool change point, and then the spindle moves to the tool change point to place the tool holder on the tool holder. The servo motor rotates the tool holder to be installed on the spindle to the tool change point through the fan-shaped rotating plate, and the spindle grabs the required tool holder to complete the tool change. However, as the types of tool holders increase, the circumference of the fan-shaped rotating plate must be enlarged to place more tool holders. The enlargement of the circumference of the fan-shaped rotating plate will inevitably cause the diameter to increase and occupy space. In the limited working space, it is not possible to install a too large fan-shaped rotating plate, so that part of the tool holder is arranged on another tool magazine mechanism, and the workpiece to be processed must be moved to another processing machine for further processing. This situation also applies to the robot arm (similar to the servo motor in the previous case) and the tool connected to the robot arm (similar to the tool holder in the previous case), and there is room for improvement in use.

Therefore, the inventor proposes a chain-type clamping magazine for placing a plurality of tools, comprising: a clamping seat having a cover and a seat, the seat having a track and a drive disk, the drive disk having a plurality of drive teeth; a clamping chain located on the track and movable along the track, the clamping chain having a plurality of clamps and a plurality of connecting parts, the clamping The clamps are arranged along the track, and every two adjacent clamps are respectively connected to the two ends of the connector, and the connection between the clamp and the connector can pivot; a motor is connected to the drive disk, and when the motor is started, the drive disk is driven to rotate. When the drive disk rotates, the drive gear pushes the clamp chain to move the clamp chain along the track.

Furthermore, the clamp includes a clamping member, an assembly member and a first roller, the clamping member clamps the tool, the clamping member is connected to the assembly member, the assembly member is connected to the first roller, and the first roller rolls along the track.

Furthermore, the track is mainly composed of a first ring wall, a second ring wall and the base body. The first ring wall and the second ring wall are locked on the base body in parallel at intervals, and the track is formed between the first ring wall and the second ring wall.

Furthermore, the clamps are arranged at equal intervals along the track.

Furthermore, the cover is fixed to the base by screws.

Furthermore, the assembly is fixed to the clamping member by screws.

Furthermore, the connecting member is fixed to the assembly member by screws.

Furthermore, the assembly is connected to a second roller, and the second roller rolls on the first annular wall.

Furthermore, the base is connected to a bracket.

Furthermore, the bracket is mounted on a work table.

Based on the above technical features, the following effects can be achieved:

1. The clamp chain of the present invention is equipped with multiple tools. When the clamp chain moves on the clamp seat, the tools on the clamp chain will move with the clamp chain, so that each tool on the clamp chain can move with the clamp chain to a position that is convenient for removal.

2. The clamp chain of the present invention moves on the track through the first roller and the second roller, thereby reducing the resistance during movement, making the movement smoother, and at the same time avoiding direct friction between the clamp chain and the track during movement, thereby increasing the service life of the clamp chain.

3. The present invention can be used in conjunction with a robotic arm. The clamp chain can be used to move the tool to the range of motion of the robotic arm so that the robotic arm and the tool can be assembled. When there are many types of tools, the clamp chain can be extended beyond the range of motion of the robotic arm without affecting the assembly of the robotic arm and the tool.

4. The present invention can be used with multiple robotic arms at the same time. Multiple robotic arms are distributed in the moving range of the clamp chain, so that the range of movement of each robotic arm partially overlaps with the moving range of the tool. That is, each robotic arm can be assembled with the tool on the clamp chain to present the appearance of a workstation, and multiple robotic arms can share tools to reduce the configuration cost.

Combining the above technical features, the main functions of the chain-type clamp library of the present invention will be clearly presented in the following embodiments.

First, please refer to the first and second figures, which illustrate the structure of the embodiment of the present invention, including a clamp seat 1, a motor 3 and a bracket 4. The clamp base 1 includes an upper cover 11 and a lower base 12. The cover 11 and the base 12 are locked by screws A. A motor 3 and a bracket 4 are connected to the bottom of the base 12. When the cover 11 and the base 12 are disassembled, a circular track 121 and a drive plate 122 can be seen in the base 12. The track 121 has a clamp chain 2, and the clamp chain 2 can move along the track 121. The drive plate 122 has a plurality of drive teeth 123. The drive plate 122 is connected to the motor 3. When the motor 3 is started, the drive plate can be driven by the motor 3. 122 rotates, and when the driving disk 122 rotates, the driving tooth 123 will push the clamp chain 2, so that the clamp chain 2 moves along the track 121. The cover 11 restricts the clamp chain 2 from moving on the track 121 of the base 12. Please refer to the second figure A. The track 121 of this embodiment is composed of the first ring wall 124, the second ring wall 125 and the base 12, wherein the first ring wall 124 and the second ring wall 125 are locked on the base 12 in parallel at intervals, and the track 121 is formed between the first ring wall 124 and the second ring wall 125.

Please refer to the second and third figures for further explanation of the structure of the clamp chain 2. As mentioned above, the clamp chain 2 includes a plurality of clamps 21 and a plurality of connectors 22. Each clamp 21 is arranged on the track 121 at equal intervals, and every two adjacent clamps 21 are respectively connected to the two ends of the connector 22, wherein the connection between the clamp 21 and the connector 22 can be pivoted to form the clamp chain 2. The clamp 21 of this embodiment includes a clamping member 211, an assembly member 212, two first rollers 213 and two second rollers 214, wherein the clamping member 211 and the assembly member 212 are fixed by screws A, and the left and right ends of the assembly member 212 are respectively connected to a connecting member 22, and the assembly member 212 and the two connecting members 22 are also fixed by screws A. It is worth mentioning that the connector 22 and the assembly 212 can pivot around the screw A. The purpose of the pivoting is to allow the clamp chain 2 to move along the track 121. Since part of the track 121 is curved, the clamp chain 2 needs to change its overall shape along the track 121 when moving. Therefore, the overall shape of the clamp chain 2 can be changed according to the shape of the track 121 by the pivotable connector 22 and the assembly 212. Please refer to the second figure and the third figure for reference. The two first rollers 213 and the two second rollers 214 are fixed on the clamp 21, wherein the two first rollers 213 are fixed on the assembly 212 in a vertical direction, and the two second rollers 214 are fixed on the clamp 21 in a horizontal direction, and the two second rollers 214 are arranged on opposite sides of the clamping notch of the clamp 21. The clamp 21 is moved by the first rollers 213 rolling in the track 121 and the second rollers 214 rolling on the first annular wall 124. The two second rollers 214 are arranged between the two first rollers 213 and the clamping notch of the clamp 21 in the normal direction of the track 121, thereby reducing the resistance of the clamp chain 2 during movement, making the movement smoother and avoiding direct friction between the clamp chain 2 and the track 121 during movement, thereby shortening the service life of the clamp chain 2. With the above arrangement, when the clamp 211 moves on the track 121, the weight of the clamp 211 (and the clamped tool) is applied to the first annular wall 124 via the two second rollers 214. The weight of the clamping member 211 (and the clamped tool) can be borne by the first annular wall 124 through the second roller 214. The two aforementioned first rollers 213 are only used to move in the track 121 to guide the direction of the clamping member 211. The first rollers 213 do not need to bear the weight of the clamping member 211 (and the clamped tool).

Please refer to the fourth to sixth figures for explaining the actual use of the embodiment of the present invention. In actual use, the clamp 21 on the clamp chain 2 clamps different types of tools B. The tool B of this embodiment is taken as an example of the tool B used by the robot arm. When the motor 3 is started to rotate the drive disk 122, it can be seen that the drive tooth 123 is between the two clamps 21. When the drive disk 122 rotates, the drive tooth 123 pushes the clamp 21, and then the entire clamp chain 2 moves along the track 121. As a result, the tool B on the clamp chain 2 moves along the track 121 with the clamp chain 2, so that each tool B on the clamp chain 2 can be moved to a position that is convenient for removal through the clamp chain 2.

Please refer to Figures 7 to 9 for the description of the present invention when used in conjunction with a robot C. Figures 7 and 8 show the use of a chain-type fixture library in conjunction with a robot C, which is fixed to a work table 5 via a bracket 4, and the robot C is located near the chain-type fixture library. The fixture chain 2 allows different types of tools B to move within a moving range D, and the range E of the robot C overlaps with the moving range D of the tool B, so that the robot C and the tool B can be assembled. When there are many types of tools B, the fixture chain 2 can be extended outward according to the use requirements without affecting the assembly of the robot C and the tool B. Figure 9 shows a chain-type fixture library used with multiple robotic arms C. Multiple robotic arms C are distributed around the fixture chain 2 so that the range of motion E of each robotic arm C partially overlaps with the range of motion D of the tool B. This means that each robotic arm C can be assembled with the tool B on the fixture chain 2 to present a workstation. Multiple robotic arms C can share the tool B to reduce the configuration cost of the workstation.

Combined with the description of the above embodiments, the operation, use and effects of the present invention can be fully understood. However, the above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of implementation of the present invention. That is, simple equivalent changes and modifications made according to the scope of the patent application and the content of the invention description are all within the scope of the present invention.
