The welding assembly 13 is an existing equipment and will not be described in detail here. A reduction motor 14 fixedly connected to the base 1 is provided on the right side of the lifting and adjusting assembly 12, and the reduction motor 14 is used to move and rotate the welded cylinder, which is beneficial for welding the inside of the cylinder.

The clamping telescopic rod 204 points to the gear ring 2 A clamping plate 205 is fixed to one end of the axis of 02, and the clamping plate 205 is arc-shaped, which is convenient for the clamping plate 205 to contact with the outer wall of the cylinder to achieve clamping and fixing of the cylinder.
