Armature support pallets are provided with support assemblies which have parts that cooperate with structural features of the armature assembly they carry to maintain the rotary orientation there

Armature support pallet

The operation of a flier-type armature winding machine is monitored to detect if a tang connection is missed and for interrupting the operation of the machine in such event. Differences in wire usage between those cases in which a tang connection is successfully made and those cases in which a tang connection is missed are detected and, if the differences are substantial, the operation of the armature winding machine is terminated. The monitoring is done with a shaft encoder and an add-subtract counter by which is computed the degrees of forward and reverse rotation of a guide pulley over or around which the wire is coursed. In a modification, up and down movements of a dancer pulley are monitored to provide an indication of wire usage.

Method and apparatus for monitoring and controlling an armature winding

A plurality of commutators are inserted into a commutator supply tube in end-to-end, tang-oriented relationship to form a row of commutators mutually aligned along a common axis. The ends of the supply tube may be at least partly covered during transport and handling. The commutator-filled tube is oriented on a horizontal axis in axial alignment with a commutator-receiving nest. A first commutator in the tube is inserted into the nest by pushing on the opposite end of the row. The nest is moved into alignment with a placing ram and the commutator pushed into the ram nosepiece after which the ram is operated to press the commutator onto an armature shaft. The process is repeatedly carried out until all of the commutators are removed from the tube. The process may also include a commutator tang forming step and a tang ejection capability. An empty tube is replaced successively by other tubes filled with commutators so that the process can be repeatedly carried out over an indefinite period of time. An intermittently-operated conveyor having tube-receiving seats is used to convey the tubes to the area of the commutator placing machine. A commutator feed plate having plural commutator-receiving nests is provided that intermittently rotates through a limited angle about a horizontal axis to successively move the nests from station-to-station. Open windows in the feed plate provide space for operation of the ram.

Commutator handling apparatus

For winding a field coil onto a two pole stator core of the type having pole pieces with coil support extensions with outwardly extending coil retaining fingers, two pairs of winding forms are removably supported on carriages manipulated to mount the winding forms on the coil support extensions before winding a stator and to remove the winding forms after winding. During winding, the winding forms are clamped to the coil support extensions by spring-biased latch mechanisms interconnecting the opposite pairs of winding forms. Each latch mechanism includes a rotatable latch member which, in one embodiment, is rotatable about an axis that is generally parallel to the longitudinal axis of the stator being wound or, in another embodiment, is rotatable about an axis generally perpendicular to the longitudinal axis of the stator being wound.

Commutator handling method and apparatus

Connection of stator coil lead wires to terminals with channels is accomplished using an industrial robot and tooling for guiding the lead wires into the terminal channels and for crimping the lead wire to the terminals before the wires are severed. Also, lead wire placing assemblies are provided with hooks at each end of a stator being wound for holding the start wires away from the stator pole pieces.

Stator coil winding and lead termination method and apparatus

The insulating coating on the portion of a conductor wire to be fused to a terminal is evaporated prior to the fusing operation by the use of a focused inductive heater, such as an ultrasonic or laser beam, focused on the portion of the wire from which the insulating coating is to be removed. Following removal of the insulating coating in this manner, the terminal and the conductor wire are fused together by application of heat and pressure thereto. The invention is described for use in connecting armature coil lead wires to commutators having bars with tangs.

Process for terminating insulated conductor wires

An armature core subassembly and a commutator to be assembled thereon are each centered on a common axis and rotated relative to one another until a desired angular alignment is obtained between a side edge of a commutator bar and the armature core slots. This orientation is maintained while the commutator is advanced to and pressed onto the armature shaft. A commutator placing machine is described in which a tang-oriented commutator is loaded into the nosepiece of a ram assembly and the ram assembly is rotated by a stepper motor until an edge of a commutator bar is detected at a predetermined location by an optical edge detector. Prior machines for tang-orientation and orientation by insulating gaps between commutator bars are also described.

Armature assembly method

Armature assembly apparatus

Both the inner commutator shield assembly and the outer commutator shield assembly of a flier-type armature winding machine include quick release means by which armature-specific tooling parts may be quickly removed and replaced by other armature-specific tooling. The armature rotator assembly has a modular collet assembly which may be removed simply by manually removing a pair of connectors and replaced by another modular collet assembly. By employing these assemblies, an entire tooling changeover can be effected by one relatively unskilled in tooling set-up techniques in a few minutes without the use of tools.

Armature winding machine with quick-change tooling

The mounting plate of a winding form assembly for a flier-type armature winder has a split hub with an axial bore clamped to a bearing at the end of the flier spindle. The mounting plate has spaced segments defined by splits. A clamp screw has a head confined in a bore in the split hub so that, upon loosening the screw, it causes the plate segments to be forced apart, thereby increasing the size of the axial bore so that the plate may easily be removed from the bearing.

Winding form assembly

Wire trimmer blades having sharp edges are located at the forward end of the inner commutator shield of an armature winding machine. Clamps gripping the start and finish wires of the armature are moved to cause the wire segments gripped by the clamps to be stretched and then severed at the sharp edges.

Armature winding method and apparatus

A winding form of the type used with flier-type winding machines and of the type comprising a chuck body and a pair of side plates for guiding wire onto a dynamoelectric core to be wound has one or both side plates yieldably and pivotally mounted on the chuck body. The yieldably mounted side plates may be used for tightly winding coils or for preventing snagging of the wire on the core.

Winding form

A double flier armature winding machine is provided with two wire trimming assemblies, one for each flier, each having a trimming head with a sharp edge against which a lead wire is severed by abruptly moving a wire clamp gripped to the lead wire in a direction to cause the wire to be stretched over the sharp edge.
