Description

Technical Field

[0001] The utility model relates to a guide anti-collision tooling for a motor stator, belonging to the technical field of motors. Background Art

[0002] With the development of new energy vehicles, motors, as the main power components of automobiles, have higher and higher requirements for motor matching accuracy. The stator is one of the most critical components of the motor. Before processing the stoppers and end faces at both ends of the stator, the stator needs to be hoisted and inserted into the expansion tire. The expansion tire tightens the inner diameter of the stator core. The wire package inside the stator may first collide with the end face of the expansion tooling, causing the wire package inside the stator to deform and be damaged, resulting in significant losses. The step in the stator processing process where the wire package is most likely to be damaged is when the stator is about to be inserted into the expansion tire. Without the assistance of tooling, the operator relies on the naked eye to control it, and cannot achieve safe and effective control of the process. There is a risk of damaging the wire package, causing the motor to burn out. Therefore, a new solution is needed to solve this problem. Utility Model Content
