Description

Technical Field

[0001] The utility model relates to the field of devices for grinding or polishing, and particularly to a device for grinding the outer surface of a circular stator. Background Art

[0002] In the field of motor manufacturing, especially for those motor types with a circular stator structure and a large number of coils, a series of unique challenges are faced during their design and manufacturing processes. Among them, the insulation protection problem between stator coils is particularly crucial. Since such motors usually contain a large number of closely arranged copper wire coils, not only does the insulation protection level between the coils need to reach a high standard to prevent electrical breakdown or short circuit, but also the stability and durability of the coils during the operation of the motor need to be ensured. However, in traditional manufacturing processes, it is often difficult to perfectly achieve the insulation protection between coils, especially in a circular stator structure where the coils are dense and the shape is complex.

[0003] Furthermore, although the stator coils made of copper wire have excellent electrical conductivity, their physical properties determine that they are prone to deformation under external forces, which directly affects the overall performance and service life of the motor. To enhance the stability of the coils and improve the insulation effect, the industry generally adopts the method of dipping in paint, that is, using varnish (a commonly used motor insulation paint) to dip the stator as a whole. Varnish can effectively penetrate into the coil gaps to form a solid insulation layer, and at the same time play a role in fixing the coils and protecting the circuit from external environmental erosion.

[0004] However, after the stator is dipped in paint and dried, an irregular varnish film often remains on its outer surface. This film not only affects the cleanliness of the stator appearance, but more importantly, it makes the outer diameter size of the stator irregular and difficult to directly and smoothly fit into the pre-designed motor stator housing. To solve this problem, the traditional method is to manually grind the outer surface of the stator to remove the excess varnish residue and reach the required outer diameter size standard.

[0005] However, the above method has significant drawbacks: one is low efficiency, time-consuming and laborious; the other is the poor working environment, and long-term contact with chemical substances such as varnish may have an adverse impact on the physical health of operators. In view of the above background, it is particularly important to develop an efficient and automated device for grinding the outer surface of a circular stator. Summary of the Utility Model
