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. Stator winding apparatus for winding field coils onto pole pieces of a stator located at a winding station using wires supplied from sources of wire under tension, said apparatus comprising:

a winding head assembly located adjacent said winding station that winds coils of wire on the stator at said winding station;

two pairs of winding forms for guiding the wires wound into coils wound on the stator at the winding station;

a pair of winding form-loading mechanisms that move said winding forms toward and away from one another at said winding station; and

a pair of programmably adjustable form lock assemblies adjacent said winding station that lock said winding forms to the stator located at said winding station and, after the winding operation is completed, unlock said winding forms from the same stator while said stator is still located at said winding station.

2. Stator winding apparatus for winding field coils onto pole pieces of a stator located at a winding station using wires supplied from sources of wire under tension, said apparatus comprising:

a winding head assembly located adjacent said winding station that winds coils of wire on the stator at said winding station;

two pairs of winding forms for guiding the wires wound into coils wound on the stator at the winding station;

a pair of winding form-loading mechanisms that move said winding forms toward and away from one another at said winding station; and

a pair of programmably adjustable form lock assemblies adjacent said winding station that lock said winding forms to the stator located at said winding station and, after the winding operation is completed, unlock said winding forms from the same stator while said stator is still located at said winding station, each of said pair of programmably adjustable form lock assemblies comprising a pair of parallel, vertically movable form locking blades adapted to straddle a stator at said winding station, a movable carriage, means mounting one of said form locking blades on said carriage, and a motor for moving said carriage and thereby said one of said form locking blades horizontally toward and away from the other of said form locking blades.

3. A stator winding apparatus for winding field coils onto pole pieces of a stator located at a winding station using wires supplied from sources of wire under tension, said apparatus comprising:

a winding head assembly located adjacent said winding station that winds coils of wire on the stator at said winding station;

two pairs of winding forms for guiding the wires wound into coils wound on the stator at the winding station;

a pair of winding form-loading mechanisms that move said winding forms toward and away from one another at said winding station, one of said pair of winding form-loading mechanisms comprising a carriage mounted for movement toward and away from said winding station, a horizontal post extending from said carriage toward said winding head, clamp means mounted on said carriage for releasably clamping a pair of said winding forms to said horizontal post, and means for moving said carriage with said winding forms clamped thereto toward said winding head and positioning said last mentioned winding forms in the bore of a stator to be wound; and

a pair of form lock assemblies adjacent said winding station that lock said winding forms to the stator located at said winding station and, after the winding operation is completed, unlock said winding forms from the same stator while said stator is still located as said winding station.

4. The apparatus of claim 3 wherein said clamp means comprises a pair of air actuators having piston rods engageable with said last mentioned winding forms.

5. Stator winding apparatus for winding field coils onto pole pieces of a stator located at a winding station using wires supplied from sources of wire under tension, said apparatus comprising:

a winding head assembly located adjacent said winding station that winds coils of wire on the stator at said winding station;

two pairs of winding forms for guiding the wires wound into coils wound on the stator at the winding station;

a pair of winding form-loading mechanisms that move said winding forms toward and away from one another at said winding station; and

a pair of form lock assemblies adjacent said winding station that lock said winding forms to the stator located at said winding station and, after the winding operation is completed, unlock said winding forms from the same stator while said stator is still located at said winding station, each of said form lock assemblies including a user-operable adjustment mechanism that, without disassembly, adjusts the associated form lock assembly to permit said winding forms to be locked to stators having substantially different stack heights.

6. The apparatus of claim 5 wherein the adjustment mechanism of each of said form lock assemblies includes a user-operable drive motor.

7. The apparatus of claim 6 wherein the drive motor of each adjustment mechanism is a programmably-controllable drive motor.

8. Stator winding apparatus for winding field coils onto pole pieces of a stator located at a winding station using wires supplied from sources of wire under tension, said apparatus comprising:

a winding head assembly located adjacent said winding station that winds coils of wire on the stator at said winding station;

two pairs of winding forms for guiding the wires wound into coils wound on the stator at the winding station;

a pair of winding form-loading mechanisms that move said winding forms toward and away from one another at said winding station; and

a pair of adjustable form lock assemblies adjacent said winding station that lock said winding forms to the stator located at said winding station and, after the winding operation is completed, unlock said winding forms from the same stator while said stator is still located at said winding station, wherein each of said form lock assemblies is adjusted by use of a user-operable, programmably-controllable drive motor.

9. The apparatus of claim 8 wherein, for each of said pair of adjustable form lock assemblies, said form lock assembly comprises a pair of parallel, movable form locking blades adapted to straddle a stator at said winding station, a movable carriage on which one of said form locking blades is mounted, and wherein the drive motor used to adjust said form lock assembly moves said carriage and thereby said one of said form locking blades toward and away from the other of said form locking blades.
