1,174,350. Winding and inserting stator coils. WESTINGHOUSE ELECTRIC CORP. 31 Aug., 1967 [23 Sept., 1966], No. 39904/67. Heading B3A. A stator-coil winding and transfer arrangement comprises at least one coil form 32-35 having a winding position and a transfer position, means 24 for winding at least one coil on a coil form, and a transferring device for receiving the wound coils from the coil forms, which device comprises elongated fingers 6 spaced parallel to each other along a circle, and the or each coil form, in the coil transferring position, being in direct coil transfer relation to the coil transferring device. An assembly 16, which includes a cluster of the coil forms, is supported on bars 18, 19 extending through a housing 20 and each coil form is offered up in turn to the winding mechanism 24. The number of coil forms depends on the number of poles in the dynamoelectric machine for which the coils are intended. Each coil form has straight surface portion (9) to shape the sections 9a and it may be collapsed by moving either of sections 1 or 2 relative to the other Fig. 5 (not shown). When the coils have been wound, a rod 49 is actuated by an air cylinder 60 to pivot the coil forms about pins 31 by pivoted links 50-53. The assembly 16 is then swung over into alignment with the comb structure 12 with the fingers 6 thereof in registry with openings 5 in the coil forms. A lever 4 is actuated to collapse the coil form and the coils are slipped into the spaces 7 between the fingers 6. The coils are then transferred from the comb 12 to a stator core 72 by wedges. The levers 4 may be provided with cam surfaces which engage stationary cam surfaces disposed in the path of movement of the levers so as to actuate the levers during movement of the coil forms under the action of the air cylinder 60. |
