Abstract
A coil assembly machine for automatic loading of stator cores for dynamoelectric machines, automatic winding insertion, high speed wedge manufacture, automatic wedge insertion, and automatic core removal from the machine is provided in a construction of relatively low cost and high productivity. The machine is designed to operate in conjunction with conventional coil winding devices and improves manufacturing efficiency at relatively low cost. In the preferred embodiment, a four position arrangement is employed. Each position includes an upper tooling assembly of an axial insertion machine. An operator places wound coils on the upper axial insertion tooling. The upper insertion tooling then rotates to a stator core placement position, where the core is placed on the tooling and wedges are positioned for placement in the core. Thereafter, the core and winding move to an insertion position where the coils are inserted axially and wedges are placed in slots of the stator core. The now winding loaded core rotates to a removal position, where the winding/core combination is removed from the machine. Operations are controlled so the various processes occur in a predetermined timed relationship.
