The inner wall of the movable groove 401 is symmetrically slidably connected to a movable seat 402. The outer wall of the movable seat 402 is rotatably connected to a rotating disk 403. The outer walls of the two rotating disks 403 are respectively provided with connecting grooves 404 for the cylinder 1 and the end 2 to connect and enter.

[0038] In this embodiment: the cylinder 1 and the end 2 are respectively connected into the connecting grooves 404 on the two rotating disks 403, and then the first motor 405 is started. The first motor 405 drives the movable seat 402 to slide in the movable groove 401, and the two movable seats 402 move closer to each other, thereby driving the cylinder 1 and the end 2 to contact, so that the end 2 fits tightly to one end of the cylinder 1 and maintains a coaxial setting. The welding gun 604 is driven to move and contact the connection between the cylinder 1 and the end 2 through the cooperation of the parts in the welding mechanism 6, and then the second motor 407 is started.
