Inner bore cleaning method and device for plastic packed motor stator

Abstract

The invention discloses an inner bore cleaning method and device for a plastic packed motor stator, which are characterized in that: the stator is compacted through a compacting device and then rotated, and burrs on an inner bore of the stator are ground by a rotary flexible grinding head to achieve the cleaning aim. In the invention, the flexible grinding head instead of an original traditional manual cleaning method is used for cleaning the inner bore of the plastic packed motor stator, therefore, the cleaning efficiency is greatly improved, the grinding force is uniform and stable when theflexible grinding head runs, and the pass percent after cleaning is high; and a dust collector is used for removing dust generated after cleaning so that the influence of dust on the health of the human body is effectively reduced, and therefore, the body health of workers is guaranteed.

Description

technical field [0001] The invention relates to a method and a device for cleaning motor parts, in particular to a method and a device for cleaning the inner hole of a plastic-encapsulated motor stator. Background technique [0002] The plastic-encapsulated motor uses plastic packaging technology to package the stator core and winding of the motor with engineering plastics, which can cancel the traditional motor stator insulation treatment process and the metal casing of ordinary motors. Due to its compact structure, high energy conversion efficiency, and excellent safety and insulation performance, plastic-encapsulated motors are widely used in various industries. Especially in the field of household appliances, it is being vigorously promoted. However, due to the difficulties in the manufacturing process, the manufacturing cost, the qualified rate of the product, and the production efficiency are limited. [0003] The plastic-sealed motor is composed of a plastic-sealed ...

AI Technical Summary

Problems solved by technology

When the plastic-sealed stator of the plastic-sealed motor is plastic-sealed, due to the injection pressure, the inner hole of the stator core will inevitably have BMC material burrs, which must be cleaned, otherwise, the gap between the plastic-sealed stator and the rotor will be affected when the plastic-sealed motor is assembled. In severe cases, it may even cause the plastic-sealed stator to rub against the rotor, which is very detrimental to the performance of the plastic-sealed motor and will affect the performance index of the plastic-sealed motor, which will reduce the efficiency of the plastic-sealed motor, increase the temperature rise, and increase the noise during operation.

At present, when cleaning the inner hole of the stator of the plastic-sealed motor, the manual cleaning method with a brush is used. This method has the following problems: 1. The cleaning efficiency is low. It takes 30 seconds to clean the inner hole of the stator of a plastic-sealed motor; 2. Due to manual cleaning Uneven strength will lead to low pass rate of cleaning; 3. There will be a lot of dust floating, which will affect the health of workers
