Motor rotor casting processing technology

Abstract

The invention relates to a motor rotor casting processing technology, a motor rotor casting processing device is used, the motor rotor casting processing device comprises a bottom plate, a movable supporting mechanism and a polishing and painting mechanism, the device is characterized in that a sliding groove is formed in the middle of the upper end face of the bottom plate, a movable supporting mechanism is installed in the sliding groove in a sliding fit mode, and a polishing and paint brushing mechanism is arranged above the movable supporting mechanism and installed on the upper end face of the bottom plate. The problems that an existing device cannot conduct grinding and insulating treatment on a motor rotor at the same time, time and manpower are wasted, the machining efficiency of the motor rotor is low, and the effect is poor can be solved, and the problems that the existing device cannot conduct reciprocating grinding on the surface of the motor rotor, the grinding effect is poor, the smoothness of the surface of the motor rotor is affected, and the insulation effect of the motor rotor and the use safety of the motor are influenced due to the fact that insulation paint cannot be uniformly coated on the motor rotor are solved.

Description

technical field [0001] The invention relates to the technical field of motor rotors, and specifically proposes a casting process for motor rotors. Background technique [0002] Motors play a very important role in life and production, and are currently used in many fields. In layman's terms, the motor rotor is the rotating part of the motor, and it is also the rotating part of the motor. The motor consists of two parts, the rotor and the stator, which are used to realize the conversion of electrical energy and mechanical energy and mechanical energy and electrical energy. Most of the existing motor rotors are molded by casting, that is, metal inserts are put into the mold, and then BMC plastic is injected into the mold to be heated and molded. The surface of the motor rotor manufactured in this way will have burrs, which will affect the smoothness of the motor rotor surface. To prevent the coils from flying out when the motor is rotating, and to prevent the motor load from...

AI Technical Summary

Problems solved by technology

Most of the existing motor rotors are molded by casting, that is, metal inserts are put into the mold, and then BMC plastic is injected into the mold to be heated and molded. The surface of the motor rotor manufactured in this way will have burrs, which will affect the smoothness of the motor rotor surface. To prevent the coils from flying out when the motor is rotating, and to prevent the motor load from heating, it is necessary to apply insulating varnish to the motor rotor silicon steel sheet for insulation treatment to increase the leakage protection of the motor and improve the safety performance of the motor during use

[0003] When insulating the motor rotor, according to the needs, it is necessary to perform surface burr grinding on the casted motor rotor to increase the smoothness of the motor rotor surface and improve the insulation treatment effect of the motor rotor: the existing motor rotor casting processing device has the following defects : 1. The existing motor rotor casting processing device cannot perform grinding and insulation treatment on the motor rotor at the same time, and equipment needs to be replaced, which wastes time and manpower, resulting in low processing efficiency and poor effect on the motor rotor; 2. Existing motor rotor casting processing The device cannot reciprocally grind the surface of the motor rotor, the grinding effect is poor, which affects the smoothness of the motor rotor surface, and the insulating paint cannot be evenly painted on the motor rotor, which affects the insulation effect of the motor rotor and the safety of the motor during use
