[0023] When in use, the C-shaped clamping frame 12 can accommodate parts of various shapes, and the combination of the first threaded rod 16 driven by the motor 13 and the clamping plate 15 can achieve precise clamping of the parts, which not only ensures the stability and accuracy of the clamping, but also enables the clamp to adapt to a wider variety of part shapes. The addition of rubber pads further enhances the adaptability of the clamp to parts of different shapes. The rubber pads can fill the gap between the clamp and the part, improve the tightness and stability of the clamping, and avoid damage to the surface of the part.

[0024] The moving assembly also includes a driving motor 18 and a second threaded rod 19. The base of the driving motor 18 is fixedly mounted on the side wall of the workbench 1. The output shaft of the driving motor 18 is fixedly connected to one end of the second threaded rod 19. The other end of the second threaded rod 19 is fixedly mounted on an inner wall of one side of the moving groove 21 through a bearing. The bottom end of the moving block 20 is threadedly connected to the second threaded rod 19. Through the operation of the driving motor 18, the rotation of the second threaded rod 19 can be precisely controlled, thereby driving the moving block 20 to move in the moving groove 21. By rotating the second threaded rod 19, the moving distance and position of the moving block 20 can be precisely controlled, thereby achieving precise clamping of automotive parts at different positions.

[0025] A support assembly is provided at the top end of the moving block 20 and the bottom end of the second moving seat 22, and the support assembly includes a first electric push rod 6 and a limit rod 7. The base of the first electric push rod 6 is fixedly installed inside the top end of the moving block 20, and the output shaft of the first electric push rod 6 passes through the bottom end of the second moving seat 22 and extends to the inside of the bottom end of the second moving seat 22. Limiting grooves are provided on both sides of the top end of the moving block 20 and both sides of the bottom end of the second moving seat 22, and both ends of the limit rod 7 are placed in the limit grooves. The setting of the first electric push rod 6 enables the second moving seat 22 to move up and down, thereby adjusting the height of the clamping assembly. The two ends of the limit rod 7 are respectively placed in the limit grooves of the moving block 20 and the second moving seat 22, which effectively prevents the second moving seat 22 from deflecting or shaking during the movement, thereby ensuring the accuracy and stability of the clamping assembly.

[0026] A through groove is provided in the middle of the top of the workbench 1, a filter plate 8 is placed above the through groove, and a collecting box 2 is installed inside the through groove. By arranging the through groove and the filter plate 8 on the workbench 1, waste residue and smoke can fall into the collecting box 2 below through the filter plate 8, thereby realizing the centralized collection and treatment of waste residue and smoke.

[0027] A handle 3 is fixedly installed on the outside of the collecting box 2, and a collecting chamber 17 is opened inside the collecting box 2. Waste slag and smoke generated during the welding process can fall into the collecting chamber 17 through the filter plate 8, thereby achieving effective collection of waste slag and smoke. The design of the handle 3 makes it easier to open and close the collecting box 2.

[0028] A fixed seat 4 is fixedly installed on the other side surface of the workbench 1, and a first movable seat 5 is arranged on the top of the fixed seat 4. The top of the fixed seat 4 and the bottom of the first movable seat 5 are provided with the same supporting assembly. The cooperation of the first electric push rod 6 and the limit rod 7 ensures the stability and accuracy of the first movable seat 5 during the movement. Since the first movable seat 5 and the second movable seat 22 can move and adjust the height independently, this makes it possible to more accurately position and fix the components during the welding process, thereby improving the accuracy and consistency of welding.

[0029] A fixing plate 9 is fixedly installed on one side of the first movable seat 5, a spring seat 10 is fixedly connected to one side of the fixing plate 9, and a placement plate 11 is fixedly connected to one end of the spring seat 10. The placement plate 11 is set in an L shape. During the welding process, due to the influence of welding stress and deformation, automobile parts sometimes have slight displacements. The existence of the spring seat 10 can absorb these displacements to a certain extent, reduce the damage of welding stress to the fixture and parts, and also protect the quality of the welded joint.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
