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 mechanisms 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. The programmably adjustable parts include a lead pull assembly having wire grippers mounted on carriages driven in respectively opposite directions along planes that a perpendicular to the axis of reciprocation and oscillation of the winding shuttle by a programmably controlled drive motor. Air actuators on carriage are used to pivot the wire grippers and to control the vertical spacing of the wire grippers.
