Description

technical field [0001] The invention relates to the field of motor manufacturing, in particular to process equipment for removing surface burrs and aluminum chips during the manufacturing process of motor rotors. Background technique [0002] The asynchronous motor consists of two parts, the stator and the rotor. The rotor is a cast aluminum part (ie, iron core) including silicon steel sheets. During the production process, the cylindrical surface of the die-cast aluminum rotor needs to be turned. Aluminum filings will enter the rotor core and produce burrs (aluminum whiskers) on the rotor surface. These aluminum filings and burrs must be removed before assembly to reduce the core loss and load stray loss of the motor rotor. Otherwise, the performance of the magnetic field and the efficiency of the motor will be reduced. [0003] The patent document with the application number 200410093271.2 discloses a "motor rotor surface pickling treatment process". The steps of the proc...

Problems solved by technology

[0004]1. Since the hydrochloric acid solution is applied to the surface of the rotor at normal temperature for acid treatment, the hydrochloric acid solution will interact with the aluminum filings in the rotor core at normal or low temperature. And the chemical reaction of surface burrs is slow, which affects the pickling effect

[0005]2. Since the rotor enters the drying process after pickling, the residual hydrochloric acid solution on the surface of the rotor cannot be effectively treated, and the residual hydrochloric acid solution will corrode the rotor. Not only affect the performance of the motor, but also affect the service life of the rotor
