[0023] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0024] The first implementation method:

A spring 12 is sleeved on the surface, a fixing groove 22 is provided on the inner wall of the circular groove 6, and the upper and lower ends of the circular plate 7 are fixedly connected with fixing blocks 23 adapted to the fixing groove 22. The fixing blocks 23 can prevent the circular plate 7 from separating from the lifting seat 5. A rectangular groove 13 is provided at one end of the lifting seat 5 away from the arc plate 2, and one end of the plug-in rod 11 away from the telescopic plate 10 is fixedly connected to the inner wall of the rectangular groove 13. The end of the telescopic plate 10 away from the limit block 9 is inserted into the inside of the rectangular groove 13, the front end of the spring 12 is fixedly connected to the rear end of the telescopic plate 10, and the rear end of the spring 12 is fixedly connected to the inner wall of the rectangular groove 13.

[0026] This solution can be achieved. When in use, the tubular workpiece is placed under the limit frame 8, the limit frame 8 is rotated according to the diameter of the tubular workpiece to be fixed, and the limit frame 8 suitable for the workpiece is selected to fix the workpiece. Several limit frames 8 are provided with grooves, and the cross-sectional lengths of the grooves are different, so it can be used to fix tubular workpieces with different diameters. After selecting a suitable limit frame 8, the spring 12 pushes the telescopic plate 10, and the front end of the telescopic plate 10 is sleeved on the limit block 9 to prevent the limit block 9 from rotating, thereby preventing the circular plate 7 from rotating. After that, the hydraulic rod 4 is started to pull the lifting seat 5 to move downward, and then the limit frame 8 moves downward to clamp and fix the tubular workpiece. When the clamp is used to fix the tubular workpiece, its operation steps are simple and time-saving.

[0027] The second implementation method:

[0028] Based on the first embodiment, this embodiment adds structures such as a waste box 15 and a sponge board 16, and the rest of the parts are consistent with the first embodiment.

[0029] Figure 7-8 It is shown that a pair of pull-out slots 14 are provided at the upper end of the welding table 1, a waste box 15 is inserted inside the pull-out slot 14, a sponge board 16 is arranged above the waste box 15, a reinforcement frame 17 is fixedly connected to the surface of the sponge board 16, the lower end of the reinforcement frame 17 is fixedly connected to the upper end of the welding table 1, a pair of side ends of the waste box 15 are fixedly connected to a rectangular block 18 and a first magnetic block 20, the rectangular block 18 can be used to prevent the waste box 15 from moving upward in the pull-out slot 14, an inner wall groove 19 slidably connected to the rectangular block 18 is provided on the inner wall of the pull-out slot 14, and a second magnetic block 21 that attracts the first magnetic block 20 is fixedly connected to the inner wall of the pull-out slot 14.

[0030] This solution can be implemented. When using, when fixing a tubular workpiece, the workpiece needs to be inserted into the sponge board 16 so that the inner wall of the sponge board 16 squeezes the workpiece. Then, the workpiece needs to be rotated and pulled back and forth so that different positions on the workpiece and the inner wall of the sponge board 16 produce friction, thereby cleaning the surface of the workpiece and improving the cleanliness of the workpiece. Then, the foreign matter dropped from the workpiece is moved into the waste box 15. When a certain amount of foreign matter is collected in the waste box 15, the waste box 15 needs to be removed from the welding table 1 and the foreign matter inside it can be disposed of.

[0031] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
