Abstract
A stator manufacturing apparatus is equipped with spindles as twisting and bending jigs, an inner guide having a first supply flow path and a suction flow path formed in the interior thereof, and an outer guide having a second supply flow path formed in the interior thereof. Further, the spindles have receiving members in which insertion recesses are formed. Through holes are formed in the receiving members, and the receiving members are formed with lateral holes therein which allow the interiors of the insertion recesses to communicate with each other.
Claims10
A stator manufacturing method for obtaining a stator by twisting and bending coil segments in which first straight portions and second straight portions of the coil segments are inserted into slots formed along a circumferential direction of a stator core, comprising the steps of:
- inserting ends of the first straight portions or the second straight portions, which are exposed from the slots, into insertion recesses formed respectively in a plurality of twisting and bending jigs, and thereafter, twisting and bending the coil segments by rotating the twisting and bending jigs;
- and
- separating the ends of the first straight portions or the second straight portions away from the insertion recesses, and thereafter, simultaneously suctioning interiors of all of the insertion recesses.
A stator manufacturing apparatus configured to obtain a stator by twisting and bending coil segments in which first straight portions and second straight portions of the coil segments are inserted into slots formed along a circumferential direction of a stator core, comprising:
- a plurality of twisting and bending jigs configured to be rotated, and having receiving members in which insertion recesses are formed, ends of the first straight portions or the second straight portions, which are exposed from the slots, being inserted into the insertion recesses;
- and
- a suction unit configured to suction interiors of the Insertion recesses;
- wherein the receiving members of the twisting and bending jigs are arranged concentrically, and the suction unit is configured to simultaneously suction the interiors of all of the insertion recesses.
