As shown in fig. 1 to 8, the workpiece holding device of the present invention includes: the device comprises a shell 1, an x-direction clamping assembly 2, a y-direction clamping assembly 3, a z-direction clamping assembly 4 and a telescopic assembly, wherein the x-direction clamping assembly 2 is arranged on the shell 1 and used for clamping a workpiece in the x direction, the y-direction clamping assembly 3 is arranged on the shell 1 and used for clamping the workpiece in the y direction, and the z-direction clamping assembly 4 is arranged in the shell 1 and used for clamping the workpiece in the z direction; the telescopic assembly can release clamping forces applied to the workpiece in the x direction, the y direction and the z direction. In other words, the workpiece clamping device can clamp the workpiece in the directions of x, y and z, and can effectively ensure the clamping and positioning precision of the workpiece when the workpiece is turned over and rotated, so that the dispensing precision is improved. And the workpiece clamping device can be opened in the directions of x, y and z simultaneously through the telescopic assembly, so that the clamping efficiency of the workpiece is improved.
For example, the workpiece of the present embodiment is a base, which is a structural member in a camera. The base is, for example, ring-shaped, and the outer side surface of the base has four surfaces, which are respectively denoted as a surface, B surface, C surface, and D surface. The inner ring (the position opposite to the A surface) of the base is provided with a clamping surface E. In the dispensing operation, dispensing is required to be sequentially performed on the surface A, the surface B, the surface C and the surface D. That is, when dispensing is performed on the base, the base needs to be rotated so that different dispensing surfaces face the dispensing mechanism. Before starting dispensing, the base is fed (i.e., the base is placed on the workpiece clamping device), and the clamp needs to be kept in a horizontal position during feeding. Because the glue dispensing head moves downwards to dispense glue on the surface of the workpiece, and the glue dispensing position of the base is arranged on the side surface of the base, after the workpiece is fed, the side surface of the base is required to be rightly pointed. Therefore, in operation, the workpiece holding device needs to be subjected to rollover and rotation operations. If the workpiece clamping device does not have good clamping force, the workpiece can fall off the workpiece clamping device or shift in position during rollover and rotation, so that the operation is affected.
Specifically, the x-direction clamping assembly 2 includes: the x-direction fixing block 21, the x-direction clamping block 22 and the x-direction moving unit 23, the x-direction fixing block 21 is fixed on the upper end surface of the housing 1, the x-direction clamping block 22 penetrates the upper end surface of the housing 1, the x-direction moving unit 23 is arranged in the housing 1, and the x-direction moving unit 23 is connected with the x-direction clamping block 22. The x-direction fixing block 21 is disposed opposite to the x-direction clamping block 22. The x-direction moving unit 23 includes: the movable block 231 and the ejector rod 232, the movable block 231 is arranged inside the shell 1 in a penetrating way along the x direction, the ejector rod 232 is arranged inside the shell 1 in a penetrating way along the y direction, and one end of the movable block 231 is connected with the x-direction clamping block 22. The moving block 231 is provided with a cam 233, and the cam 233 is positioned on one side of the ejector rod 232; an abutment surface 2321 is provided on a side of the plunger 232 adjacent to the cam 233. One end of the moving block 231 is provided with a connecting screw 234, the other end of the moving block 231 is provided with a first elastic member 235, and the x-direction clamping block 22 is connected with the connecting screw 234.
That is, the x-direction fixing block 21 is fixed, and the x-direction clamping block 22 is movable in the x-direction. The ram 232 is movable in the housing 1, and when the ram 232 is not subjected to external pushing force, the abutment surface 2321 of the ram 232 is not in contact with the cam 233, and at this time, the x-direction clamping block 22 is in a state of clamping the workpiece. When the jack 232 receives an external pushing force, the abutment surface 2321 of the jack 232 contacts the cam 233, and then the cam 233 moves in a direction approaching the x-direction fixed block 21 as the jack 232 moves in the y-direction, and the cam 233 and the moving block 231 are fixed, so that the moving block 231 moves in a direction approaching the x-direction fixed block 21. When the moving block 231 moves, the x-direction clamping block 22 is also driven to move in a direction approaching the x-direction fixing block 21, and at this time, the first elastic member 235 is compressed. When the external pushing force of the ejector pin 232 is removed, the moving block 231 is pushed to move away from the x-direction fixed block 21 under the action of the first elastic member 235, and the x-direction clamping block 22 is reset.
For example, the ejector pin 232 is further provided with a through hole 2322, the through hole 2322 is provided with a pin 24, and the pin 24 penetrates through the through hole 2322 from top to bottom. The engagement of the through-hole 2322 and the pin 24 can prevent the ejector pin 232 from coming out of the housing 1 due to excessive external thrust or erroneous operation.
Specifically, the y-direction clamping assembly 3 includes: the device comprises a y-direction fixing block 31, a y-direction clamping block 32 and a rotating shaft 33, wherein the rotating shaft 33 penetrates through the shell 1 along the x direction, the y-direction fixing block 31 is fixed on the upper end face of the shell 1, the y-direction clamping block 32 is rotatably connected with the rotating shaft 33, and the upper end of the y-direction clamping block 32 penetrates through the upper end face of the shell 1. The y-direction clamping assembly 3 further comprises: the third elastic member 34, the third elastic member 34 is located in the outer casing 1, and the third elastic member 34 abuts against the lower end of the y-direction clamping block 32. In other words, the y-clamp block 32 is rotatable about the rotation axis 33, the y-clamp block 31 is stationary, and the y-clamp block 32 is in a state of being tensioned against the workpiece when the y-clamp block 32 is not subjected to external thrust. When the y-direction clamp block 32 receives an external pushing force, the y-direction clamp block 32 can rotate around the rotation shaft 33, and is switched to a release state.
For example, the y-clamp block 32 includes: the y-direction clamping portion 321, the y-direction abutting portion 322 and the y-direction connecting portion 323, wherein the y-direction clamping portion 321 is fixedly connected with the upper end of the y-direction connecting portion 323, the y-direction abutting portion 322 is fixedly connected with the lower end of the y-direction connecting portion 323, and the y-direction connecting portion 323 is rotatably connected with the rotating shaft 33. The y-direction clamping portion 321 is disposed opposite to the y-direction fixing block 31, the third elastic member 34 is in contact with the y-direction abutting portion 322, and a side of the y-direction abutting portion 322 away from the third elastic member 34 is an inclined surface. When the inclined surface of the y-direction abutting portion 322 receives an external pushing force, the third elastic member 34 is compressed, and the y-direction connecting portion 323 rotates around the rotation shaft 33, so that the y-direction clamping portion 321 moves in a direction approaching the y-direction fixing block 31. At this time, the y-direction clamp assembly 3 is in a released state. When the external pushing force is removed, the y-direction clamping block 32 is reset under the action of the third elastic member 34.
Specifically, the z-direction clamping assembly 4 includes: the clamping rod 41 and the second elastic piece 42, the clamping rod 41 is connected with the rotating shaft 33 in a rotating mode, the upper end of the clamping rod 41 penetrates through the upper end face of the shell 1, the second elastic piece 42 is located inside the shell 1, and the second elastic piece 42 abuts against the lower end of the clamping rod 41. The clamp lever 41 includes: the z-direction pressing portion 411, the z-direction abutting portion 412, and the z-direction connecting portion 413, wherein the z-direction pressing portion 411 is fixedly connected to an upper end of the z-direction connecting portion 413, and the z-direction abutting portion 412 is fixedly connected to a lower end of the z-direction connecting portion 413. For example, the number of the clamping bars 41 is two, and the number of the second elastic members 42 matches the number of the clamping bars 41. The second elastic member 42 abuts against one side of the z-direction abutting portion 412, and one side of the z-direction abutting portion 412 away from the second elastic member 42 is an inclined surface. The z-direction pressing portion 411 is configured to press against the clamping surface E of the workpiece, and the z-direction pressing portion 411 cooperates with the upper end surface of the housing 1 to clamp the workpiece in the z-direction.
When the z-direction pressing portion 411 receives external pushing force, the clamping lever 41 rotates around the rotation shaft 33, at this time, the workpiece may be placed on the upper end surface of the housing 1, after the workpiece is placed, the external pushing force is removed, and the z-direction pressing portion 411 is reset under the action of the second elastic member 42 to press the workpiece.
That is, the x-direction clamping assembly 2, the y-direction clamping assembly 3 and the z-direction clamping assembly 4 of the present invention are all in a clamping state when no external pushing force is applied; the x-direction clamping assembly 2, the y-direction clamping assembly 3, and the z-direction clamping assembly 4 can be simultaneously opened (i.e., released from clamping) when the external pushing force is engaged. Therefore, the workpiece can be easily and rapidly clamped, and the clamping efficiency is improved. And the workpiece can be positioned in the directions of x, y and z, so that the position of the workpiece in the rollover and rotation processes is prevented from being deviated, and the positioning accuracy of the workpiece is improved.
Specifically, an assembly port 11 is formed on one side of the housing 1. The y-direction abutting portion 322 and the z-direction abutting portion 412 are both located in the fitting opening 11. The telescoping assembly includes: the telescopic driving piece 5, the first push block 6 and the second push block 7, the telescopic driving piece 5 is located on one side of the shell 1, which is provided with the assembly opening 11, the first push block 6 and the second push block 7 are fixed at the telescopic end of the telescopic driving piece 5, and the position of the first push block 6 corresponds to the assembly opening 11. When the telescopic driving piece 5 stretches out, the first pushing block 6 and the second pushing block 7 can be driven to move towards the direction close to the shell 1 at the same time, the first pushing block 6 can be inserted into the assembly opening 11, and thrust is applied to the y-direction abutting part 322 and the z-direction abutting part 412 at the same time; the second pushing block 7 can push against the ejector pin 232, and apply pushing force to the ejector pin 232.
For example, the first pushing block 6 includes a first connection portion 61 and a first pushing portion 62, the first connection portion 61 is fixedly connected to the first pushing portion 62, and the first connection portion 61 is fixedly connected to the telescopic end of the telescopic driving member 5. The second push block 7 includes: the second connecting portion 71 and the second pushing portion 72, the second connecting portion 71 and the second pushing portion 72 are fixedly connected, and the second connecting portion 71 and the telescopic end of the telescopic driving member 5 are fixedly connected. The second pushing portion 72 penetrates the first connecting portion 61, and the second pushing portion 72 is located above the first pushing portion 62. Since the y-direction abutting portion 322 and the z-direction abutting portion 412 are located farther inward in the fitting port 11, the first pushing portion 62 is closer to the fitting port 11 than the second pushing portion 72. Thus, when the telescopic driving piece 5 extends, the first pushing portion 62 abuts against the y-direction abutting portion 322 and the z-direction abutting portion 412, and the second pushing portion 72 abuts against the ejector pin 232, and the two actions are performed simultaneously (not sequentially), so that only one action can be realized to simultaneously open the x-direction clamping assembly 2, the y-direction clamping assembly 3 and the z-direction clamping assembly 4, and convenience and rapidness can be realized.
According to the invention, through the structural improvement of the workpiece clamping device, on one hand, three clamping assemblies can be effectively opened by one key, so that the workpiece can be conveniently taken and placed; on the other hand, the positioning precision of the workpiece and the stability of the workpiece in the rotating process can be effectively improved.

The first pushing block 6 and the second pushing block 7 are driven to move towards the direction approaching to the shell 1 by the telescopic driving piece 5, when the first pushing block 6 applies pressure to the y-direction abutting part 322 and the z-direction abutting part 412, the y-direction clamping part 321 and the z-direction pressing part 411 simultaneously move towards the direction approaching to the y-direction fixed block 31, and at the moment, the y-direction clamping assembly 3 and the z-direction clamping assembly 4 are in an open state; when the second pushing block 7 applies pressure to the push rod 232, the push rod 232 pushes the moving block 231 to move along the x direction, so that the x-direction clamping block 22 moves towards the x-direction fixing block 21, and at this time, the x-direction clamping assembly 2 is in an open state.
When the workpiece is placed, the telescopic driving piece 5 drives the first pushing block 6 and the second pushing block 7 to retract; at this time, the x-direction clamping block 22 is reset by the first elastic member 235; the z-direction pressing part 411 is reset under the action of the second elastic member 42, and the y-direction clamping part 321 is reset under the action of the third elastic member 34; at this time, the x-direction clamping assembly 2, the y-direction clamping assembly 3, and the z-direction clamping assembly 4 can clamp the workpiece in three directions of x, y, and z.
