Description

technical field [0001] The invention belongs to welding equipment, in particular to an automatic welding machine for the stator auxiliary pole of an automobile starter. Background technique [0002] A plurality of auxiliary poles are evenly distributed on the inner wall of the stator housing of the automobile starter, and projection welding is used between the auxiliary poles and the stator housing during processing. At present, the stator shell and the auxiliary pole are usually welded by an ordinary resistance welding machine. When welding, the stator shell needs to be held, the stator shell is placed on the lower electrode of the resistance welding machine and pressed against the auxiliary pole, and the welding is completed through the upper electrode. After welding, manually rotate the stator housing to divide the angle equally, and then continue the welding of the next auxiliary pole. The existing problems are: 1. Due to manual rotation of the stator housing for indexi...

AI Technical Summary

Problems solved by technology

The existing problems are: 1. Due to manual rotation of the stator housing for indexing, the indexing of the stator housing is inaccurate, resulting in uneven distribution of the auxiliary poles of the stator, which directly affects the fixing of the magnetic steel in the subsequent process, resulting in waste products in the end; 2. Both the stator shell and the stator auxiliary poles rely on manual operation, the work efficiency and automation are low, and the labor intensity is high
