[0025] The fixing mechanism can fix the part to be welded, which is placed at the center of the turntable 2, so that the turntable 2 can drive the part to be welded to rotate when it rotates.

[0026] A three-jaw chuck 3 is located directly above the center of the turntable 2 and is capable of reciprocating vertically. The three-jaw chuck 3 is driven by a cylinder assembly, and the cylinder assembly is rotatably connected to the three-jaw chuck 3.

[0027] The three-jaw chuck 3 can clamp the workpiece to be welded and then bring it close to the workpiece to be welded fixed on the turntable 2 through the cylinder assembly, so that the two workpieces to be welded are in close contact. When the turntable 2 rotates, the friction generated by the pressure makes the two workpieces to be welded rotate synchronously.

[0028] The welding machine 4 is located on the operating table 1 and faces the center of the turntable 2. The welding machine 4 is capable of reciprocating in the vertical direction through the transmission assembly.

[0029] When the workpiece to be welded rotates, the welding machine 4 can be used to perform circumferential welding on the welding position. By controlling the rotating speed of the workpiece placing turntable 2 through the PLC, the welding speed and quality can be guaranteed, thereby replacing manual welding, saving labor costs, improving work efficiency, and further improving the practicability.

[0032] When the bidirectional screw rod 21 rotates, the nut seat 22 can be driven to move, thereby realizing the purpose of moving close to or away from each other. When the nut seat 22 moves close to each other, the contact piece 24 can be driven to move close to each other through the extension piece 23, thereby realizing the fixation and positioning of the workpiece to be welded by the contact piece 24 tightly adhering to the workpiece to be welded.

[0033] Further, a slot is formed in the workpiece placing turntable 2 for the extension piece 23 to move towards the center of the workpiece placing turntable 2, and the contact piece 24 is an elastic piece.
