In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0022] The utility model provides a clamp that can be used for parts of different shapes, including a workbench 5, a clamping drive unit is provided at the center of the workbench 5, and the clamping drive unit moves left and right on the workbench 5 under the action of a moving unit, and the moving unit includes a moving screw seat 9 arranged at the bottom of the clamping drive unit, a screw 12 is screwed in the moving screw seat 9, both ends of the screw 12 are rotatably connected to a support frame 6 installed at the bottom of the workbench 5, and one end of the screw 12 passes through the support frame 6 and is connected to a moving motor 13. The rotation of the moving motor drives the screw to rotate, so that the moving screw seat drives the clamping drive unit to move, thereby realizing the movement of the clamping drive unit on the workbench. The clamping drive unit can move left and right on the workbench under the action of the moving unit, providing a flexible clamping position selection to accommodate parts of different sizes and shapes.

[0023] The clamping drive unit includes a clamping platform 11, on which a driving block 18 is provided which can be raised and lowered. A driving hole 20 is provided at the center of the driving block 18. The driving hole 20 is provided corresponding to a driving sleeve 21 installed on the clamping platform 11. A driving rod 19 provided with a driving cylinder runs through the driving sleeve 21. The driving rod 19 is provided in the driving hole 20 and connected to the driving block 18. A sliding block 8 is provided at the bottom of the pushing fixture 16. The sliding block 8 is connected to a sliding groove 7 on the clamping platform 11. A transverse spring 8 connected to the sliding block 8 is provided in the sliding groove 7. When the driving block moves downward under the action of the driving cylinder, the pushing fixture is driven to move outward. When the driving block moves upward under the action of the driving cylinder, the pushing fixture is reset under the action of the transverse spring. The automation is high and no excessive human intervention is required.

[0024] One or both ends of the driving block 18 are driving surfaces inclined inward, and the driving surface corresponds to the driven surface of the pushing fixture 16. The pushing fixture 16 is slidably mounted on the clamping table 11, and the pushing fixture 16 is arranged corresponding to the positioning fixture 14 located on the workbench 5. A dust cover 17 is provided at the upper end of the driving block 18. The dust cover is provided at the upper end of the driving block to effectively prevent the erosion of debris and coolant during the processing process, thereby extending the service life.

[0025] Both sides of the driving block 18 are driving surfaces, that is, both ends of the driving block 18 are provided with a pushing fixture 16, one of the pushing fixtures 16 corresponds to the positioning fixture 14 fixedly set on the workbench 5, and the other pushing fixture 16 corresponds to the positioning fixture 14 movably installed on the workbench 5. The positioning fixture 14 movably installed on the workbench 5 is slidably installed in the fixture sliding groove on the workbench 5, and the rear end of the positioning fixture 14 is provided with a positioning screw 2, and the positioning screw 2 is screwed in the driving sleeve 3, and the driving sleeve 3 is connected to the fixture driving motor 4. Under the action of the fixture driving motor, the driving sleeve is driven to rotate, and the rotation of the driving sleeve drives the positioning screw in and out of the driving sleeve, thereby driving the positioning fixture to move on the workbench.

[0026] The clamping ends of the pushing fixture 16 and the positioning fixture 14 are both provided with a plurality of clamping components 23, the rear end of the clamping component 23 is a T-shaped connector 22, the T-shaped connector 22 is rotatably disposed in the T-shaped slot of the pushing fixture 16 or the positioning fixture 14, the clamping component 23 is semicircular, and the arc end of the clamping component 23 is rotatably embedded in the pushing fixture or the positioning fixture. The clamping component is designed to be semicircular, and the arc end is rotatably embedded in the pushing fixture or the positioning fixture, providing a variety of clamping shape options to adapt to parts with different contours.

[0027] The clamping end of the clamping assembly 23 is provided with a plurality of clamping heads 24, and the rear end of the clamping head 24 is provided with a T-shaped connector, which is rotatably arranged in the T-shaped slot of the clamping assembly. The clamping head 24 is semicircular, and the arc end of the clamping head 24 is rotatably embedded in the clamping assembly 23, and the clamping end of the clamping head 24 is provided with clamping teeth. The clamping head is designed to be semicircular, and the clamping end is provided with clamping teeth, which provides a stronger clamping force and a better clamping effect, and is suitable for fine processing and parts with complex shapes.

[0028] When in use, first adjust the position of the clamping drive unit and the positioning fixture at the other end to adapt to workpieces of different sizes. The distance between the two ends of the clamping drive unit and the positioning fixture is 1-5cm greater than the width of the workpiece, which is convenient for placing and taking the workpiece. At the same time, it can also enable the clamping drive unit to clamp the workpiece in the driving mode. After the position is adjusted, the workpiece is placed in a suitable position, and the driving block moves down, driving the push fixture to slide horizontally, shortening the distance between the positioning fixture and achieving clamping of the workpiece.

[0029] The setting of the pushing fixture and the positioning fixture of the utility model can be quickly adjusted to be suitable for parts of various shapes and sizes, and the operation process is simple. At the same time, the fixture can clamp from multiple directions, which improves the stability of the parts and ensures the accuracy of the processing process. It is especially suitable for parts with irregular shapes or complex geometric features.
