Abstract

A stator winding machine has a turret plate mounted for rotation about a vertical axis with stator clamp mechanisms mounted at spaced locations around its periphery for clamping stators to the turret plate with the axes of the stators coplanar with the axis of reciprocation and oscillation of the winding shuttle used to wind coils on the stators. The turret plate is repeatedly indexed in one direction about its vertical center axis to repeatedly sequentially move each of the stator clamp mechanism to a load/unload station, an optional idle station, a winding station, a coil lead terminating station, and then back to the load/unload station. Parts of the machine are quickly replaceable and other parts are programmably adjustable to accommodate different stator configurations.

Claims

1. A method for winding a stator using a stator winding machine having a turret plate mounted for rotation about a vertical axis, at least three stator clamp assemblies mounted on said turret plate at spaced locations around the periphery of said turret plate, each of said clamp assemblies including a releasable clamp mechanism for holding a stator core with its center axis extending horizontally and substantially perpendicularly with respect to said vertical axis and with the end face of said stator core most remote from said vertical axis spaced a fixed horizontal distance from said vertical axis, and a winding head having a reciprocating and oscillating wire winding needle, said method comprising the steps of:

clamping said stator to said turret plate by one of said stator clamp assemblies located at a load/unload station to thereby locate said stator with its axis extending horizontally;

rotatably indexing said turret plate to position said stator at a winding station with its axis remaining in a horizontal plane;

while said stator is located at said winding station, clamping winding forms to said stator, temporarily connecting coil start leads to wire clamps mounted on said turret plate adjacent said stator winding machine by which said stator is gripped, winding coils of wire onto said stator at said winding station by operation of said winding head, and temporarily connecting coil finish leads extending from coils wound on said stator to wire clamps mounted on said turret plate adjacent said winding machine;

thereafter rotatably indexing said turret plate to position said stator at a coil lead terminating station;

removing said coil leads from said wire clamps and connecting said coil leads to terminals on the core of said stator at said coil lead terminating station;

rotatably indexing said turret plate to position said stator at said load/unload station; and

unclamping said stator from said turret plate and removing it from said turret plate.
