[0002] Metal welding is a common process used to connect metal parts together. Common welding methods include arc welding, gas shielded welding, laser welding, etc. When welding circular tube-like metal parts, they are usually placed upright on a welding workbench. At this time, in order to ensure the stability of the circular tube-like metal parts during welding, a clamp is used to clamp and fix the circular tube-like metal parts.

[0036] Reference Figure 2 The clamping mechanism 5 includes a guide block 501, a connecting sleeve 502, a connecting plate 503 and an arc-shaped clamping plate 504. The guide block 501 is arranged in the guide groove 4, and the upper and lower ends of the guide block 501 both pass through the guide groove 4. The connecting sleeve 502 is arranged at the upper end of the guide block 501. The connecting plate 503 is plugged and arranged inside the connecting sleeve 502, and the top end of the connecting plate 503 passes through the inside of the connecting sleeve 502. A groove 8 is opened on one side of the connecting plate 503. The arc-shaped clamping plate 504 is arranged on one side of the connecting plate 503 for clamping and fixing the metal parts.

[0037] By adopting the above technical solution, when the guide block 501 moves, it can drive the connecting sleeve 502 to move, and the movement of the connecting sleeve 502 can drive the arc clamping plate 504 on the connecting plate 503 to move, so that the circular tube-like metal parts can be clamped by the arc clamping plate 504.

[0038] Reference Figure 3 and Figure 4 The positioning mechanism 6 includes a spring 601, a limit block 602 and a positioning head 603. The spring 601 is arranged inside the groove 8, the limit block 602 is slidably arranged in the groove 8, and one end of the limit block 602 is connected to the spring 601. The positioning head 603 is arranged at the end of the limit block 602 away from the spring 601, and the end of the positioning head 603 away from the limit block 602 passes through the groove 8; one side of the connecting sleeve 502 is provided with a plurality of positioning holes 9 used in conjunction with the positioning head 603, and one end of the positioning head 603 is plugged into the corresponding positioning holes 9.

[0039] By adopting the above technical solution, the positioning head 603 is pressed to be inserted into different positioning holes 9, so that the use height of the arc clamping plate 504 can be adjusted, which facilitates stable clamping of different positions of circular tube-like metal parts.

[0040] Reference Figure 2The adjustment mechanism 7 includes an electric push rod 701, a disc 702 and three connecting rods 703. The electric push rod 701 is arranged at the upper end of the base 3, the disc 702 is arranged at the upper end of the electric push rod 701, and the three connecting rods 703 are all hinged at the upper end of the disc 702, and the top end of the connecting rod 703 is hinged to the bottom end of the guide block 501, which is used to drive the guide block 501 to move.

[0041] By adopting the above technical solution, the electric push rod 701 drives the disc 702 to move, and the movement of the disc 702 can drive the connecting rod 703 to rotate. The rotation of the connecting rod 703 can push the three guide blocks 501 to move synchronously, so that the circular tube-like metal parts can be quickly clamped and the circular tube-like metal parts can be located in the center position on the processing table 2.

[0042] Reference Figure 1 A guide rod 10 is disposed inside the guide groove 4 , and the guide block 501 is slidably connected to the guide rod 10 .

[0043] By adopting the above technical solution, the connecting sleeve 502 is slidably connected to the guide rod 10, so that the arc-shaped clamping plate 504 is more stable when moving.

[0044] Working principle: When the utility model is in use, the electrical components in the present application are all connected to an external power supply and a control switch. When the circular tube-like metal parts are clamped and fixed, they are placed on the upper end of the processing table 2, and then the electric push rod 701 works to drive the disc 702 to move. The movement of the disc 702 can drive the connecting rod 703 to rotate. The rotation of the connecting rod 703 can push the guide block 501 to slide on the guide rod 10. The guide block 501 slides through the connecting sleeve 502 and the connecting plate 503 to drive the arc clamping plate 504 to move. Then, the circular tube-like metal parts can be quickly clamped by the three arc clamping plates 504 that move simultaneously. The circular tube-like metal parts can be held and located in the center position on the processing table 2, which greatly improves the efficiency of clamping and fixing the circular tube-like metal parts. At the same time, by pressing the positioning head 603 to move it out of the positioning hole 9, the limiting fixation of the connecting plate 503 is cancelled, and then the connecting plate 503 can be pulled to move to a suitable position. At this time, the elastic force of the spring 601 can make the spring 601 reinserted into the corresponding positioning hole 9 to limit and fix the connecting plate 503, so that the use height of the arc clamping plate 504 can be adjusted, thereby facilitating the stable clamping of the circular tube-like metal parts at different positions.

[0045] When the utility model is in use, it can not only quickly clamp the circular tube-like metal parts, but also make the circular tube-like metal parts be located in the center position on the processing table 2, and at the same time, the clamping position of the circular tube-like metal parts can be adjusted, making it more convenient to weld the circular tube-like metal parts.
