CN-122001167-A - Stator manufacturing apparatus

Abstract

The invention provides a technology capable of continuously manufacturing a plurality of stators with different coil end lengths without changing the shape of a base. The stator manufacturing apparatus includes a lifter, and a base placed on the lifter. The base is capable of holding a workpiece. The base includes a base body having a substantially cylindrical shape, and a plurality of extending pieces extending radially from a lower end of an outer peripheral surface of the base body. The lifter includes a lifter body supported in a substantially cylindrical shape so as to be rotatable horizontally, and a plurality of 1 st base holding portions and a plurality of 2 nd base holding portions extending radially from an outer peripheral surface of the lifter body. The 2 nd base holding portions are disposed on the outer peripheral surface of the lifter body at positions spaced apart from the 1 st base holding portions by a predetermined interval on the outer peripheral surface of the lifter body. The plurality of 1 st base holding portions have a different height from the plurality of 2 nd base holding portions.
