Armature winding apparatus

An armature winding apparatus comprising a collet unit having on an outer circumferential portion, an outer shield movable for a predetermined distance in a direction of a central axis of the collet unit and an inner shield rotatable at a predetermined angle around the collet unit central axis, flyers for feeding and winding wires on slots of an armature core supported by said collet unit to have an armature core central axis conform with the collet unit central axis and to be able to perform indexing rotation by the collet unit, while rotating, to form coils in succession, a mechanism for looping wires at both end portions of the coils around hooks of an armature commutator, and cutting devices for severing coil leads at a start and a finish of winding of the coil,

• wherein said cutting devices have cutter mounting members attached to said outer shield to be displaceable within a plane including the collet unit central axis and move with the outer shield in the direction of the collet unit central axis, and cutters provided at tip end portions of the cutter mounting members to be able to advance to and retreat from the collet unit central axis,
• said cutter mounting members of said cutting device have cutter ingress means for making said cutter get into the armature core side at a hook root portion of the armature commutator by rotating said inner shield a predetermined angle around the collet unit central axis, and
• said cutter ingress means comprises adjustment screws screwed into said cutter mounting members to be able to advance and retreat in a direction to intersect the collet unit central axis perpendicularly, cam surfaces, which are provided at an outer circumferential portion of said inner shield and are able to be engaged with the adjustment screws, and biasing means for pressing the adjustment screws against the cam surfaces.
