Abstract
Abstract A winding head assembly for a stator core winding machine having a turn table for supporting a number of stator cores and tooling rings for rotating the stator core relative to the turn table, the tooling rings including pivotably mounted fingers positioned between the slots in the stator core, the winding head assembly including a winding head and a spindle drive mechanism, the winding head being supported by the spindle drive mechanism for reciprocating and oscillating movement through the center of the stator core, the winding head includes a needle positioned to move through the slots of the stator core and a cam mounted for movement with and relative to the winding head a distance different than the distance of movement of the winding head, the cam being operatively connected to the needle to move the needle transversely of the winding head through an arcuate path in its movement through the slots of the stator core, the spindle drive mechanism including a dual coaxially mounted spindle, one of the spindles being connected to the winding head and the other connected to the cam, and an offset cam block for simultaneously moving said spindles through strokes of different lengths.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
138 words
In a stator core winding machine, a winding head assembly comprising a winding head having a needle mounted for transverse movement relative to the direction of motion of the winding head, a cam plate defining an arcuate groove mounted in the winding head for movement relative thereto, means operatively connecting said needle to said cam plate to follow the path of motion defined by said groove, means for linearly moving said winding head in oppositely directed strokes, said linearly moving means including means for moving said cam plate relative to said winding head to produce transverse movement of said needle through an arcuate path defined by said groove during each stroke of linear movement of said winding head, and means for rotating said winding head near the end of each stroke of linear movement of said winding head.
Claim 2
Dependent Claim
138 words
In a stator core winding machine, a winding head assembly comprising a winding head having a needle mounted for transverse movement relative to the direction of motion of the winding head, a cam plate defining an arcuate groove mounted in the winding head for movement relative thereto, means operatively connecting said needle to said cam plate to follow the path of motion defined by said groove, means for linearly moving said winding head in oppositely directed strokes, said linearly moving means including means for moving said cam plate relative to said winding head to produce transverse movement of said needle through an arcuate path defined by said groove during each stroke of linear movement of said winding head, and means for rotating said winding head near the end of each stroke of linear movement of said winding head.
Claim 3
Dependent Claim
54 words
