Tooth profile correction device and method

Abstract

The invention discloses a tooth profile correction device which comprises a flattop chisel, groove-shaped bars used for protecting tooth bottoms, a wedge-shaped block used for correcting distorted tooth profiles, an L-shaped baffle block used for correcting tooth profiles of too large fan openings, and a door-shaped protective device used for being mounted on the outer sides of normal teeth in a sleeving manner. The device can be combined for correcting teeth with abnormal tooth profile problems such as tooth profiles of distorted ends and tooth profiles of too large end fan openings, so that quick correction for abnormal tooth profiles is achieved, the rework period can be shortened, the cost is reduced, high reliability of an iron core product is met, and market requirements are quickly responded. The invention also discloses a tooth profile correction method. Through the combination use of the tooth profile correction device, damage to normal teeth during the correction process is effectively avoided, and correction and repair for abnormal tooth profiles are simply and effectively realized.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a tooth profile correction device. In addition, the invention also relates to a tooth shape correction method. Background technique [0002] In order to meet the reliability of the operation of the motor after assembly, the tooth shape of the motor stator core is required to meet the standard. [0003] However, in the actual production process, there may be problems such as bending of the teeth of the single-piece stator core punching piece, and damage to the teeth of the notch during the pressing process of the core, resulting in defects such as abnormal teeth of the stator core and excessive fanning. Moreover, the range of these defects is small, and there is no need to dismantle and repair the stacked iron core. However, if the above defects are not dealt with, it may cause problems such as difficulty in inserting wires, easy damage to the insulation at the end of the winding...

Problems solved by technology

[0003] However, in the actual production process, there may be problems such as bending of the teeth of the single-piece stator core punching piece, and damage to the teeth of the notch during the pressing process of the core, resulting in defects such as abnormal teeth of the stator core and excessive fanning. And the range of these defects is small, and there is no need to dismantle and repair the stacked iron core

However, if the above defects are not dealt with, it may cause problems such as difficulty in inserting wires, easy damage to the insulation at the end of the winding, and noise during operation, which will affect the production quality of the stator core and reduce the reliability of the motor operation.
