Then, the clamping plate 11 is driven by a hydraulic rod 13 to slide in an auxiliary groove 12 and move towards the electromagnet 10, so as to further clamp the workpiece. In the processing process, the driving motor 5 is started, the output end drives the screw rod 6 to rotate, the movable sleeve 7 moves linearly in the sliding groove 4 because the screw rod 6 is threadedly connected to the movable sleeve 7, the mounting block 8 and the heat dissipation fan 9 below the movable sleeve 7 also move, the heat dissipation fan 9 cools the metal workpiece in processing, and the mounting block 8 and the heat dissipation fan 9 can reciprocate, so that the workpiece can be cooled at different positions.

[0029] The movable sleeve 7 is slidingly connected to the inside of the sliding groove 4, the upper surface of the clamping table 1 is provided with the auxiliary groove 12, the clamping plate 11 is slidingly connected to the inside of the auxiliary groove 12, the movable sleeve 7 slides in the sliding groove 4, the movement track of the movable sleeve 7 is limited, so that the movable sleeve 7 can only move linearly along the sliding groove 4, and stable movement under the driving of the screw rod 6 is ensured. The clamping plate 11 slides in the auxiliary groove 12, the auxiliary groove 12 provides a guide for the movement of the clamping plate 11, so that the clamping plate 11 can accurately move towards the electromagnet 10 to clamp the workpiece.

[0030] The surface of the clamping plate 11 is fixedly connected with the hydraulic rod 13, the hydraulic rod 13 is fixedly connected to the inner wall of the auxiliary groove 12, when the workpiece needs to be clamped, the hydraulic rod 13 is elongated or shortened to drive the clamping plate 11 fixedly connected thereto to slide in the auxiliary groove 12, so that the clamping action on the workpiece is realized.

[0031] The lower surface of the clamping table 1 is fixedly connected with a horizontal frame plate 14, and the lower surface of the horizontal frame plate 14 is fixedly connected with a rotating disc 15.

[0032] The lower surface of the rotating disc 15 is fixedly connected with movable supporting rods 16 at four corners, and the surface of the movable supporting rods 16 is rotatably connected with a base 17, when the angle of the clamping table 1 needs to be adjusted, the rotating disc 15 is rotated in the base 17 through the movable supporting rods 16, so as to change the angle of the clamping table 1. The servo motor 19 is started, the extension shaft 20 of the output end drives the rotating disc 15 to rotate, and automatic angle adjustment is realized.

[0033] The surface of the base 17 is provided with a circular sliding groove 18, and the movable supporting rod 16 is rotationally connected to the inside of the circular sliding groove 18. The circular sliding groove 18 provides a track restriction for the rotation of the movable supporting rod 16. When the movable supporting rod 16 rotates in the circular sliding groove 18, the movement track of the movable supporting rod 16 is restricted in a circular range, thereby ensuring the rotation stability of the rotating disc 15.

[0034] The surface of the base 17 is fixedly connected with a servo motor 19, the output end of the servo motor 19 is fixedly connected with an extension shaft 20, and the extension shaft 20 is fixedly connected to the lower surface of the rotating disc 15.

[0035] In the embodiment of the present application, the implementation principle of the clamp for metal processing is as follows: the personnel places the metal workpiece to be processed on the clamping table 1, at this time, the electromagnet 10 is in an energized state, the magnetism of the electromagnet 10 is used to preliminarily adsorb and position the metal workpiece, and the workpiece is fixed at an approximate position on the clamping table 1. The operator starts the hydraulic rod 13 connected with the clamping plate 11, and the hydraulic rod 13 starts to elongate or shorten. Since the hydraulic rod 13 is fixed to the inner wall of the auxiliary groove 12, and the clamping plate 11 is slidingly connected to the inside of the auxiliary groove 12, the hydraulic rod 13 drives the clamping plate 11 to slide in the auxiliary groove 12 towards the electromagnet 10. When the clamping plate 11 closely contacts the workpiece and reaches a suitable clamping degree, the action of the hydraulic rod 13 is stopped, so as to ensure that the workpiece is firmly clamped on the clamping table 1 and prevent shaking in the subsequent processing. After the workpiece processing starts, the operator starts the driving motor 5 on the upper surface of the top plate 3. The output end of the driving motor 5 drives the screw rod 6 to rotate. Since the screw rod 6 is threadedly connected with the movable sleeve 7, and the movable sleeve 7 is slidingly connected to the inside of the sliding groove 4, the movable sleeve 7 moves linearly in the sliding groove 4. With the movement of the movable sleeve 7, the mounting block 8 and the cooling fan 9 fixedly connected to the lower surface of the movable sleeve 7 also move. The cooling fan 9 cools the metal workpiece in processing. The operator observes the surface temperature of the workpiece during processing. If local overheating is found, the speed or movement direction of the driving motor 5 can be adjusted as needed, so that the mounting block 8 and the cooling fan 9 can cool different positions of the workpiece, so as to ensure that the surface temperature of the workpiece is within a reasonable range and overheating is avoided. When the processing angle of the workpiece needs to be adjusted, the operator starts the servo motor 19 on the surface of the base 17. The extension shaft 20 of the output end of the servo motor 19 starts to rotate. Since the extension shaft 20 is fixedly connected to the lower surface of the rotating disc 15, the rotating disc 15 rotates. The movable supporting rods 16 at the four corners of the lower surface of the rotating disc 15 rotate in the circular sliding groove 18 of the base 17, thereby ensuring the rotation stability of the rotating disc 15.
