Abstract

A method of engaging wire ends of a stator assembly. The method involves advancing multiple fingers radially inwardly toward the wire ends, and rotating the fingers. The fingers have protrusions that engage the wire ends. A tooling assembly for engaging the wire ends has a first plate, a second plate, and has the fingers. The first plate has slots, and the second plate has teeth. The fingers have pins that ride in the slots of the first plate, and the fingers have teeth that mesh with the teeth of the second plate.

First claim

What is claimed is:

1. A tooling assembly for engaging wire ends of a stator assembly, the tooling assembly comprising:
a first plate having a plurality of slots residing therein;
a second plate having a set of first teeth thereon; and
a plurality of fingers engageable with the wire ends of the stator assembly, the plurality of fingers having a plurality of pins rideable in the plurality of slots of the first plate upon revolution of the first plate, the plurality of fingers having a set of second teeth meshable with the set of first teeth of the second plate upon revolution of the second plate.

2. The tooling assembly as set forth in claim 1 , wherein the plurality of slots are arcuate and, upon revolution of the first plate, the plurality of fingers advances in a radial direction toward the wire ends of the stator assembly.

3. The tooling assembly as set forth in claim 1 , wherein, upon revolution of the second plate, the plurality of fingers rotates for engaging the wire ends of the stator assembly.

4. The tooling assembly as set forth in claim 1 , wherein the plurality of fingers has protrusions that crowd pairs of wire ends of the stator assembly upon revolution of the second plate.

5. The tooling assembly as set forth in claim 1 , further comprising a first actuator interconnected with the first plate for revolving the first plate.

6. The tooling assembly as set forth in claim 1 , further comprising a second actuator interconnected with the second plate for revolving the second plate.

7. The tooling assembly as set forth in claim 1 , wherein, amid use of the tooling assembly, the plurality of fingers engages all of the wire ends of the stator assembly concurrently.

8. The tooling assembly as set forth in claim 1 , wherein, amid use of the tooling assembly, the plurality of fingers engages the wire ends of the stator assembly without movement of the plurality of fingers in a z-axis relative to the stator assembly.

9. A tooling assembly for engaging wire ends of a stator assembly, the tooling assembly comprising:
a first plate having a plurality of slots residing therein;
a second plate having a set of first teeth thereon;
a first actuator interconnected with the first plate for revolving the first plate;
a second actuator interconnected with the second plate for revolving the second plate;
a plurality of fingers engageable with the wire ends of the stator assembly, the plurality of fingers having protrusions and having a plurality of pins rideable in the plurality of slots of the first plate upon revolution of the first plate, the plurality of fingers having a set of second teeth meshable with the set of first teeth of the second plate upon revolution of the second plate, wherein the plurality of slots are arcuate and, upon revolution of the first plate, the plurality of fingers advances in a radial direction toward the wire ends of the stator assembly,
wherein, upon revolution of the second plate, the plurality of fingers rotates for engaging the wire ends of the stator assembly and the protrusions crowd pairs of wire ends of the stator assembly upon revolution of the second plate, and
wherein, amid use of the tooling assembly, the plurality of fingers engages all of the wire ends of the stator assembly concurrently without movement of the plurality of fingers in a z-axis relative to the stator assembly.
