Electric conductor insertion apparatus
An insertion apparatus includes a conductor guide member that guides a prescribed region of an electric conductor to a slot of a stator core, and a support body that supports the conductor guide member. In this configuration, the conductor guide member can float in an axial direction of the stator core.
1. An electric conductor insertion apparatus that inserts a prescribed region of an electric conductor into a slot of a stator core in which a plurality of the slots are formed, where each slot includes diameter-direction edges extending along a diameter direction of the stator core and circumferential-direction edges extending in a circumferential direction of the stator core and has insulating paper arranged therein, the electric conductor insertion apparatus comprising:
a conductor guide member that guides the prescribed region of the electric conductor into the slot; and
a support body that supports the conductor guide member and is configured to be positioned so that the conductor guide member is on the slot, wherein
the conductor guide member is provided in a manner to be floatable in an axial direction of the stator core when the conductor guide member is positioned on the slot such that a friction force between the electric conductor and the conductor guide member moves the conductor guide member in the axial direction of the stator core and into the slot.
2. The electric conductor insertion apparatus according to claim 1 , comprising:
a holding member that holds the support body, wherein
the support body is supported in a floating manner relative to the holding member by an elastic member that elastically biases the support body away from the holding member.
3. The electric conductor insertion apparatus according to claim 2 , comprising:
support body guide members that guide the support body when the support body supported in the floating manner is displaced.
4. The electric conductor insertion apparatus according to claim 3 , wherein
the support body guide members are housed in insertion holes formed in the support body.
5. The electric conductor insertion apparatus according to claim 1 , further comprising:
a second support body, wherein
the second support body supports a second conductor guide member that guides the electric conductor into the slot.
6. The electric conductor insertion apparatus according to claim 5 , wherein
the second support body is provided with a first engagement portion,
the support body is provided with a second engagement portion that engages with the first engagement portion, and
the electric conductor insertion apparatus comprises an actuator that displaces, in an integrated manner, the second support body and the support body, which are connected to each other by engaging the second engagement portion with the first engagement portion.
7. The electric conductor insertion apparatus according to claim 6 , wherein
the first engagement portion and the second engagement portion engage with each other in a state where there is a gap therebetween.
8. The electric conductor insertion apparatus according to claim 5 , wherein
the second conductor guide member includes a region that guides the electric conductor along the circumferential-direction edges of the slot.
9. The electric conductor insertion apparatus according to claim 1 , wherein
the conductor guide member includes a region that guides the electric conductor along the diameter-direction edges of the slot.
10. The electric conductor insertion apparatus according to claim 9 , wherein
the conductor guide member includes two regions,
one of the regions faces one slot of the plurality of slots, and
the remaining one region faces another slot of the plurality of slots that is adjacent to the one slot of the plurality of slots.
