[0002] A reducer is an independent component consisting of a gear transmission, a worm transmission, or a gear-worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It matches the speed and transmits torque between the prime mover and the working machine or the actuator. Currently, there are some motor shafts that include a hollow section and a connecting section. The hollow section and the connecting section need to be manufactured separately, and then the connecting section and the hollow section are coaxially welded and fixed. The current welding device has a poor degree of automation and relies on manual operation, resulting in a waste of manpower.

[0003] For example, publication number CN201921457451.2 discloses "A Motor Shaft Welding Mechanism", in which the hollow section of the input shaft is clamped and fixed by a pneumatic clamp, and then driven forward by the second cylinder.

[0004] The hollow section of the input shaft is clamped and fixed in place by the pneumatic clamp, and the translation adjustment effect of the input shaft is relatively general. The input shaft usually needs to be placed flat at a certain height during welding to facilitate the stability of the welding assembly, and the input shaft needs to be translated and adjusted from time to time to facilitate the input shaft welding process, which affects the welding efficiency of the input shaft.
