Abstract

A twisting assembly for wires of inductive windings that comprises a fixed frame. The assembly comprises: at least two bushings provided with respective channels and each of which defines at least one seat for at least one respective wire; at least one upper shaped portion which is provided, on at least one upper surface of at least one bushing, with a conveyance chute for the terminal front of at least one wire; at least one element for moving the at least two bushings for the rotation of at least one first bushing with respect to at least one second bushing for the temporary alignment of at least one upper shaped portion of at least one first bushing with at least one channel of at least one second bushing which is open toward the first bushing.

Claims14

Dependent claims

A wire-twisting assembly for wires inductive windings, comprising:

a fixed frame;
a carousel, rotatably supported on the fixed frame and having an axis of rotation:
a first bushing and a second bushing, each bushing being cylindrical and extending along the axis of rotation, the first and second bushings being coaxial and arranged in contiguous relation:
wherein the first bushing defines a plurality of first channels extending substantially parallel to the axis of rotation and defining respective first wire seats, each first wire seat being open toward the second bushing:
where the second bushing defines a plurality of second channels extending substantially parallel to the axis of rotation and defining respective second wire seats, each second wire seat being open toward the first bushing;
the second bushing further including a plurality of shaped portions formed on an upper surface thereof, each shaped portion defining a conveyance chute configured to guide a terminal end of at least one wire toward and into a corresponding first channel of the first bushing;
and
at least one drive element configured to rotate the first bushing and second bushing relative to one another about the axis of rotation,
wherein relative rotation between the first and second bushings selectively aligns the shaped portions of the second bushing with the first channels of the first bushing to facilitate insertion of the terminal end of the at least one wire into the first channel.

A method of twisting wires for inductive windings, comprising:

providing a fixed frame;
rotatably supporting a carousel on the fixed frame, the carousel having an axis of rotation;
providing a first cylindrical bushing and a second cylindrical bushing, the first and second bushings being coaxial and arranged in contiguous relation along the axis of rotation;
defining a plurality of first channels in the first bushing, each channel extending substantially parallel to the axis of rotation and defining a first wire seat open toward the second bushing;
defining a plurality of second channels in the second bushing, each channel extending substantially parallel to the axis of rotation and defining a second wire seat open toward the first bushing;
forming a plurality of shaped portions on an upper surface of the second bushing, each shaped portion defining a conveyance chute configured to guide a terminal end of at least one wire toward and into a corresponding first channel of the first bushing;
and
rotating at least one of the first bushing or the second bushing relative to the other of the first bushing or the second bushing about the axis of rotation to selectively align the shaped portions of the second bushing with the first channels of the first bushing, thereby facilitating insertion of the terminal end of the at least one wire into the first channel.
