Description

Technical Field

[0001] The utility model relates to the technical field of remanufactured generators, in particular to a synchronous grinding device for the inner and outer diameters of a generator stator. Background Technique

[0002] At present, the old paint stains remaining on the inner and outer surfaces of the stator of a remanufactured generator after painting usually need to be manually polished. This processing method is time-consuming and laborious, and cannot guarantee the quality of the product. There are also devices for polishing the inner diameter of the stator, but currently, there is a lack of equipment for simultaneously grinding and cleaning the inner and outer diameters of the stator, and the grinding and cleaning efficiency urgently needs to be improved.

[0003] Publication No. CN111660191A discloses a stator inner and outer diameter cleaning device, which includes a device frame, a workpiece loading mechanism, a stator inner diameter cleaning mechanism, and a stator outer diameter cleaning mechanism. The workpiece loading mechanism includes a moving device, a stator mounting seat, and a rotary drive motor. The stator inner diameter cleaning mechanism includes a support frame, a stator pressing device, and an inner diameter cleaning device. A rotatable pressing block assembly is provided at the lower end of the stator pressing device. The stator outer diameter cleaning mechanism includes a moving support platform and an outer diameter cleaning device. After the stator is moved to the cleaning position, the pressing block assembly presses the stator, the rotary drive motor drives the stator mounting seat to rotate, the inner diameter cleaning device cleans the inner diameter of the stator, and the outer diameter cleaning device moves into place to clean the outer diameter of the stator. Although this device can simultaneously achieve inner and outer diameter grinding and cleaning, the outer diameter of the stator is only polished once, and direct fine grinding has a high cost and reduces the uniformity of the outer diameter grinding of the stator, and it cannot timely clean the metal powder generated after the grinding operation, affecting production efficiency.
