The working process of this embodiment is as follows.
1) The pinion center hole 111 of the pinion 11 is fitted around the outer peripheries of the four supporting jaw outer positioning surfaces 243, and since the upper ends of the four supporting jaws 24 are close to each other and have a small size, they can be smoothly fitted, and the lower end surface of the pinion 11 is placed on the supporting jaw lower supporting surface 245.
Then, the sleeve central hole 121 of the sleeve 12 is sleeved on the periphery of the outer positioning surfaces 243 of the four supporting claws, and the upper end surface of the pinion 11 is attached to the lower end surface of the sleeve 12.
2) The inner supporting cylinder 231 drives the inner supporting head 232 to move upwards in a translation mode, the conical surface 2321 of the inner supporting head simultaneously pushes the inner supporting inclined surfaces 242 of the four supporting claws, the upper ends of the four supporting claws 24 respectively overcome the elastic pulling force of the ring spring 25 and swing around the axis of the connecting pin shaft 222 and back to the axis direction of the output shaft of the servo motor 21, the outer positioning surfaces 243 of the four supporting claws 24 simultaneously support the middle hole 111 of the pinion and the middle hole 121 of the sleeve, and the lower supporting surface 245 of the supporting claw supports the lower end surface of the pinion 11; the purpose of enabling the central line of the central hole 111 of the pinion to be coincident with the central line of the central hole 121 of the sleeve is achieved while the support is tight.

This enables the lower end surface of the pinion 11 to be closely fitted to the lower supporting surface 245 of the supporting claw, and the upper end surface of the pinion 11 to be closely fitted to the lower end surface of the sleeve 12.
4) The servo motor 21 drives the combination of the turret 22, the inner support assembly 23, the four support claws 24, the ring spring 25, the pinion 11, and the sleeve 12 to rotate. The welding gun cylinder 32 drives the welding gun 31 to translate, and a welding nozzle of the welding gun 31 is close to and welds the adjacent edges of the pinion 11 and the outer side of the sleeve 12. Generally, three or four welding points are uniformly welded to fixedly connect the pinion 11 and the sleeve 12, and then the welding is continuously performed, so that the welding deformation can be effectively reduced.
