Abstract
A coil insertion guide device includes a positioning jig that positions a stator core; and a guide member that is provided in the positioning jig so as to be able to contact an end face of the stator core in an axial direction. A coil inserted into the slots along the radial direction of the stator core is guided by the guide members. The guide member includes a guide groove. The guide groove includes, on a side close to the end face of the stator core, a cuff support groove that houses and supports a cuff of one of the insulating members that protrudes from the end face of the stator core, and on a side far from the end face, a coil guide groove that protrudes toward an inside of the slot more than the cuff support groove and contacts the coil to guide movement of the coil.
Claims5
A coil insertion guide device, comprising:
- a positioning jig that positions a stator core comprising a plurality of slots each having an opening that opens inward in a radial direction of the stator core and insulating members being respectively inserted into the slots;
- and
- the positioning jig comprising guide members provided in the positioning jig so as to be able to contact an end face of the stator core in an axial direction of the stator core,
- wherein the guide members are configured to guide a coil as portions of the coil are inserted into the slots along the radial direction of the stator core, and
- the guide members each comprising a guide groove,
- the guide grooves each comprising, on a side of the guide members close to the end face of the stator core, a cuff support groove that communicates with one of the slots and houses and supports a cuff of one of the insulating members that protrudes from the end face of the stator core, and on a side of the guide members far from the end face, a coil guide groove that protrudes toward an inside of the slot more than the cuff support groove and contacts the coil to guide movement of the coil along the radial direction of the stator core as the portions of the coil are inserted into the slots.
A coil insertion guide method that guides movement of a coil inserted along a radial direction of a stator core into a plurality of slots of the stator core into which insulating members are respectively inserted, the slots each having an opening that opens inward in the radial direction of the stator core, the method comprising:
- positioning a stator core using a positioning jig;
- contacting guide members of the positioning jig with an end face of the stator core in an axial direction of the stator core, the guide members each comprising a guide groove comprising, on a side of the guide members close to the end face, a cuff support groove that communicates with one of the slots and houses and supports a cuff of one of the insulating members that protrudes from the end face, and on a side of the guide members far from the end face, a coil guide groove that protrudes toward an inside of the slot more than the cuff support groove and contacts the coil to guide the movement of the coil along the radial direction of the stator core as portions of the coil are inserted into the slots;
- and
- supporting the cuffs of the insulating members by the cuff support groove, and guiding by the coil guide grooves the movement of the portions of the coil as the portions are inserted into the slots of the stator core along the radial direction of the stator core.
