Description

Technical Field

[0001] The utility model relates to the technical field of motor accessories, in particular to a rotor pole shoe processing and positioning device. Background Art

[0002] The rotor pole shoes are parts of the rotor in the generator for winding and positioning coils. Multiple rotor pole shoes are fixed outside each rotor, and coils are wound between the rotor pole shoes. The outer surface of the rotor pole shoes is an arc surface. In order to ensure that the outer surfaces of all assembled rotor pole shoes are on the same circle, the rotor and the rotor pole shoes are usually assembled, and then the arc surfaces of all rotor pole shoes are processed by lathe clamping, so that the arc surfaces of all rotor pole shoes are located in the same circle.

[0003] At present, some positioning devices clamp the rotor through a chuck and then process the rotor pole shoe. This positioning method only clamps one side of the rotor surface and cannot clamp the other side. The rotor is prone to deviation during rotation processing, resulting in errors in the processing of the rotor pole shoe. The clamping effect of this method is not stable enough.

[0004] At the same time, metal particle impurities will be generated during the processing of the rotor pole shoes. If they are not cleaned, the workers will inhale too much metal impurities, causing the metal content in the body to exceed a certain concentration, which will have many effects on the human body. In addition, the metal impurities will be blown away by the wind and will have a certain impact on the surrounding environment. Utility Model Content
