The clamping driving table 2 is fixedly connected with the lathe bed 1, a driving three-jaw chuck 8 is arranged on the clamping driving table, the driving three-jaw chuck 8 is axially parallel and is arranged in a pivoting mode, and the driving three-jaw chuck 8 is connected with a power source 7. The power source 7 comprises a driving motor 21 and a gearbox 22, wherein the driving motor 21 is fixedly arranged on the lathe bed 1 and is in transmission connection with the driving three-jaw chuck 8 through the gearbox 22. The driving motor 21 drives the driving chuck to rotate slowly after being decelerated by the gearbox 22, so that the peripheral surface of the stator core is exposed in sequence.

The linear guide rail pair 4 is horizontally and fixedly arranged on the lathe bed 1 and is parallel to the axis of the driving three-jaw chuck 8. The linear guide pair 4 comprises a slide block, the slide block is connected with the clamping mounting plate 9 in a sliding mode, and the slide block can be locked through a top thread 20. The fixed centre gripping revolving stage 3 that is equipped with on the centre gripping mounting panel 9, the top of centre gripping revolving stage 3 is equipped with axle bed 23, is equipped with the rotation axis in the axle bed 23, and the rotation axis is close to the one end of centre gripping drive table 2 sets up driven three-jaw chuck 10. The driven three-jaw disc and the driving three-jaw disc are coaxially arranged. Because this scheme is fixed the inner wall of motor stator core consequently chooses for use the internal stay formula to be the three-jaw chuck, the difference of the three-jaw chuck of internal stay formula and external stay then lies in that what install on it is the internal stay jack catch.

The polished gantry 5 is arranged in parallel with the linear guide rail pair 4 in a cross beam manner, a horizontal moving module 11 moving along the long axis of the cross beam is arranged on the polished gantry 5, a lifting moving module 12 is fixedly arranged on a moving component 16 of the horizontal moving module 11, and the polisher 6 is fixedly arranged on the moving component 16 of the lifting moving module 12. The horizontal moving module 11 and the lifting moving module 12 are linear modules of lead screw guide rails, taking the horizontal moving module 11 as an example, a lead screw nut pair 13 is pivotally arranged on a beam of the polishing gantry 5, and the lead screw nut pair 13 is in transmission connection with a stepping motor 15; the slide rail sliding table pair 14 is fixedly arranged on a cross beam of the grinding gantry 5 and is parallel to the screw rod nut pair 13; the moving assembly 16 is a square plate, and is fixedly connected with the sliding table of the sliding table pair 14 and the nut of the lead screw nut pair 13.
