The first abutment block 431 overcomes the elastic force of the second reset member 432 and slides toward the support column 12. When the abutment member 41 is located directly above the connecting member, the driving cylinder 371 works to push the sliding seat 372 downward, so that the abutment member 41 moves downward and presses against the connecting member, so that the outer wall of the cone 4121 presses against the upper end of the inner wall of the connecting member to fix the pipe fitting and the connecting member. The driving motor works to drive the driving gear 322 to rotate, drive the driven gear 323 to rotate, drive the rotating column 31 to rotate, and drive the welding gun 34 to rotate, so as to realize welding of the connection between the connecting member and the pipe fitting.

[0057] When the workpiece to be processed is a plate, the mounting rod 21 is removed, and the plate to be processed is placed on the mounting frame 22.

When the abutting member 41 is located directly above the connecting member, the driving cylinder 371 works to push the sliding seat 372 downward, so that the abutting member 41 moves downward and abuts against the connecting member, so that the outer wall of the cone 4121 abuts against the upper end of the inner wall of the connecting member to fix the pipe and the connecting member, and the driving motor works to drive the driving gear 322 to rotate, drive the driven gear 323 to rotate, drive the rotating column 31 to rotate, drive the welding gun 34 to rotate, and realize welding of the connection between the connecting member and the pipe.
