Method for terminating leads of plural wires in dynamo electric machine core

摘要

Method and Apparatus are provided for automatically disposing plural wires along predetermined trajectories, wherein the plural wires extend from coils wound in slots of dynamoelectric machine cores. Plural wires forming leads are located in predetermined positions and caused to extend along predetermined directions by means of manipulating equipment and tooling which operates automatically. In addition, the equipment and tooling cause the plural wires to become twisted and cut to form portions for connection to terminals. The tooling is provided with reference surfaces and seats which are used to bend the plural wires along the predetermined trajectories and to provide a position constraint for the portions becoming twisted. Apparatus can be provided for positioning portions of a plurality of restraining members in the spacing existing between the bridges of the coils and the end faces of a dynamo electric machine core.

主权项

1. A method for terminating leads of coils of dynamo electric machine cores, each respective lead being formed from respective plural wires, the method comprising:
manipulating the plural wires of a respective one of the leads to dispose the plural wires of the respective one of the leads along a respective predetermined trajectory in relation to a core of the dynamo electric machine cores; receiving the plural wires of the respective one of the leads in a respective seat positioned in a respective predetermined location along the respective trajectory; bending the plural wires of the respective one of the leads adjacent an entrance of the respective seat for redirecting the wires along a respective predetermined direction extending from the respective predetermined location; holding a first length of the plural wires of the respective one of the leads extending beyond the respective seat in the respective predetermined direction; rotating the first length to twist the plural wires of the respective one of the leads being held along the respective predetermined direction; and translating the first length being held to maintain a pull on a further portion of the plural wires of the respective one of the leads against a respective reference surface adjacent an entrance of the respective seat during twisting of the plural wires of the respective one of the leads.
