Center hole, positioning core axle is set in cylindrical positioning spigot groove, is connected positioning core axle with circular lower bolster with connecting bolt
Together, and alignment pin is worn and be connected between circular lower bolster and positioning core axle；
Second step, the annular lower bolster of setting on the circular lower bolster on the outside of cylindrical positioning spigot groove, in annular underlay
Laminating stator punched laminations on plate, set annular upper padding plate in stator punched laminations, and annular pressure is set on annular upper padding plate
Plate, fixing bolt sequentially passes through circular lower bolster, positioning core axle and annular pressing plate and nut links together；Center hole on lathe
It is inside and outside circle concentricity benchmark of the whole laminating stator punched laminations in lamination process with center hole under lathe；
3rd step, the frock that second step is completed and laminating stator punched laminations carry out center hole on welding sequence, lathe
It is inside and outside circle concentricity benchmark of the whole laminating stator punched laminations in welding process with center hole under lathe；
4th step, the frock and laminating stator punched laminations completed to the 3rd step pushed up on cylindrical turning process, lathe
Center hole is inside and outside circle concentricity benchmark of the whole laminating stator punched laminations in turning process under pointed orifice and lathe.
The present invention effectively solve ultra-thin yoke stator core manufacturing process be easily deformed, iron core internal-external circle concentricity 0.05
The problem of millimeter difficulty or ease ensure.Backing plate uses insulation board, prevents in iron core welding process, pressing plate welds together with iron core, nothing
Method is separated, and positioning core axle is fixed, it is ensured that iron core internal-external circle concentricity and skewed slot slope, just using split type with bolt, alignment pin
When subsequently mandrel is torn open, iron core can be extruded using press-fit approach, can be accurately positioned again.
