Fixing the inner wall of the tubular workpiece can ensure the stability of the position of the tubular workpiece during welding, which helps to avoid the problem of weld offset or uneven quality caused by the unstable position of the tubular workpiece during welding, thereby improving the overall welding quality.

[0029] A load-bearing spring 12 is arranged between the load-bearing plate 10 and the load-bearing rod 11, and the load-bearing spring 12 can drive the load-bearing rod 11 to reset. A stabilizing groove 19 is opened on the surface of the support plate 9, and the end of the L-shaped rod 17 close to the displacement device 8 is set as an inclined surface.

[0030] A No. 1 spring is arranged between the stabilizing rod 15 and the slide plate 16, and the No. 1 spring can drive the slide plate 16 to reset.

After the L-shaped rod 17 is out of contact with the U-shaped plate 13, the two slides 16 move toward each other under the elastic force of spring No. 1. The two slides 16 move toward each other, driving the two L-shaped rods 17 to move toward each other. The two L-shaped rods 17 move toward each other and drive the two arc panels 18 to move toward each other and reset to be out of contact with the inner wall of the tubular workpiece, thereby facilitating the removal of the tubular workpiece.

The No. 2 spring can drive the detection plate 213 to reset.

[0037] When the present embodiment is working, the two L-shaped rods 17 move away from each other and contact the auxiliary rod 202 and squeeze the auxiliary rod 202. The auxiliary rod 202 moves downward under the pressure of the L-shaped rod 17. The auxiliary rod 202 squeezes the return spring 205.

The spring is squeezed by the rotating rod 203 to deform and accumulate force. After the two L-shaped rods 17 move toward each other and break away from the contact with the auxiliary rod 202, the auxiliary rod 202 moves upward and resets under the action of the reset spring 205. The auxiliary rod 202 moves upward and resets to break away from the contact with the lifting plate 204. After the lifting plate 204 breaks away from the contact with the auxiliary rod 202, the rotating rod 203 rotates downward under the elastic force of the spring. The rotating rod 203 rotates downward to drive the lifting plate 204 to rotate downward and reset. The lifting plate 204 rotates and resets to hit the hollow block 206 to generate vibration.

[0038] The lifting plate 204 is squeezed by the auxiliary rod 202 so that the end of the lifting plate 204 away from the tubular workpiece rotates downward, and the end of the lifting plate 204 away from the tubular workpiece rotates downward to contact the detection rod 214 and squeeze the detection rod 214. The detection rod 214 moves downward under the pressure of the end of the lifting plate 204 away from the tubular workpiece. The downward movement of the detection rod 214 drives the detection plate 213 to move downward. The detection plate 213 moves downward to squeeze the liquid inside the detection frame 212. The liquid inside the detection frame 212 is squeezed. The liquid squeezed to the detection plate 213 enters the limit frame 215 through the hose, and the liquid entering the limit frame 215 squeezes the limit plate 216. The limit plate 216 moves downward due to the squeeze of the liquid entering the limit frame 215. The limit plate 216 moves downward, driving the limit rod 217 to move downward.
