Method for electroplating radiation ring assembly for motor and automatic clamping and positioning mechanism used by method

Abstract

The invention provides a method for electroplating a radiation ring assembly for a motor and an automatic clamping and positioning mechanism used by the method. The automatic clamping and positioning mechanism used by electroplating the radiation ring assembly for the motor comprises a bottom plate, an elastic support plate, an adjustment locking nut and a shaft; the elastic support plate is arranged on the bottom plate and consists of a plurality of equant support feet; each support foot corresponds to each magnetic shoe of the radiation ring assembly; a positioning hole is formed in the bottom plate and the elastic support plate respectively and is in threaded connection with the lower part of the shaft; and a positioning hole is formed in the center of a positioning pressing plate and is in threaded connection with the upper part of the shaft. The invention also provides the method for electroplating the radiation ring assembly for the motor; and the radiation ring assembly for the motor is positioned by using the automatic clamping and positioning mechanism. The automatic clamping and positioning mechanism has the advantages that the whole radiation ring assembly for the motor can be electroplated by the automatic clamping and positioning mechanism, and the using requirement of the motor under the high-temperature and high-humidity environment is met.

Description

technical field [0001] The invention relates to an electroplating method for a radiation ring assembly for a motor, in particular to a radiation ring assembly applied to a high-speed motor. Background technique [0002] At present, most of the rare earth permanent magnet radiation rings used in motors are an integral ring. The biggest drawback of the motor made of this integral ring is that the eddy current phenomenon that occurs during the working process of the motor will bring high pressure to the motor. The temperature will affect the working parameters of the motor, damage the motor components, and greatly reduce the service life of the motor; in addition, limited by the current domestic technical level, the overall radiation ring is still in the research and test stage in terms of large size and high performance, and cannot meet All motor field requirements. For this reason, it appears that the entire radiation ring is divided into several magnetic tiles, and then the...

Problems solved by technology

However, due to the high-temperature and high-humidity environmental requirements brought about by the high-power motor, this spliced ​​magnetic ring assembly has very strict protection requirements for the surface, otherwise the magnetic ring will be rapidly oxidized and corroded, which greatly affects shortened motor life

And because the magnetic tiles are insulated and non-conductive, it is difficult to achieve the overall electroplating protection of the radiation ring component products

[0003] One of the existing electroplating methods for motor radiation ring components is: electroplating each piece of magnetic tile first and then splicing. Although this meets the anti-corrosion requirements, the radiation ring formed only by splicing has low dimensional accuracy. Because the reprocessing will remove the coating together, the high-precision technical requirements of the inner and outer diameters and coaxiality of the product can no longer be achieved through machining, so that after the product is assembled, the air gap of the motor will eventually be affected. For ultra-high-speed motors running at high speed The vibration and noise generated during the operation are relatively large, which greatly reduces the service life of the motor; the second method of electroplating the motor radiation ring components is: use the spray paint process to spray paint on the spliced ​​radiation ring components as a whole, but the paint needs The bonding force between the paint and the substrate of the radiation ring assembly can only be achieved after a long time of high-temperature baking. The high temperature baking will greatly reduce the bonding strength of the glue, which will lead to the cracking of the radiation ring components
