Abstract
Abstract A coil assembly apparatus for axially inserting prewound coils and wedges in the slots of the stator core for an electric motor has the tooling normally associated with transfer winding and bore wedge insertion attached to a platform that is in turn hinge mounted to the machine frame. The platform is moveable from closed, operating, position to open position by a hydraulic cylinder or the like. A hydraulically activated ram transmits power to the tooling through a separable connector. In the open, raised position of the platform, the tooling attached to the underside of the hinged platform is disconnected from the ram, accessible to operator or maintenance personnel, and readily manipulatable.

Claim 2
Dependent Claim
69 words
A coil assembly apparatus, which comprises: an enclosure; a mounting platform hingedly mounted to said enclosure; means for axially inserting a prewound coil into the core of a dynamoelectric machine mounted to said platform; means for power driving said axially inserting means operatively connected to said axially inserting means; means for rotating said hingedly mounted platform; and means for detachably connecting said axially inserting means and said power-driving means.
Claim 3
Dependent Claim
136 words
The apparatus of claim 1 wherein said means for detachably connecting said axially inserting means and said power-driving means comprises an open-mouth socket having an inner wall and an outer wall with a slot opening at the open mouth of the socket, and a shaft with a disc head projecting radially therefrom to define an annular shoulder therewith, said head being of a diameter greater than the width of the slot and the shaft being of a diameter less than the width of the slot, said socket being operatively connected to one of said power-driving means and said axially inserTing means and said shaft and head being operatively connected to the other of said power-driving means and said axially inserting means, and means for maintaining the orientation of said socket with its mouth towards said head.
Claim 4
Dependent Claim
155 words
The coil assembly apparatus of claim 1 wherein said rotating means is adapted to move said hingedly mounted platform between at least a first and a second position; said axially inserting means comprises an upper tooling assembly and a lower tooling assembly mounted to said hingedly mounted platform; and said enclosure has a front panel with at least an opening in it large enough to admit said lower tooling assembly, said lower tooling assembly being positioned on the platform with respect to the hinge axis of the platform and to the front panel so as to enable said lower tooling assembly to move through said opening when said platform is moved between said first and second positions, said lower tooling assembly being contained within said enclosure at one of said first and second positions and said lower tooling assembly being outside the confines of said enclosure at the other of said first and second positions.
Claim 5
Dependent Claim
32 words
The apparatus of claim 3 wherein said rotating means comprises a hydraulic actuator, mounted on said enclosure, said actuator being operatively connected to move said platform between said first and second position.
Claim 6
Dependent Claim
102 words
A coil assembly apparatus, which comprises: an enclosure; a mounting platform rotatably mounted of said enclosure; means for axially inserting a prewound coil into the core of a dynamoelectric machine, said means comprising a first assembly mounted above said platform and a second assembly mounted below said platform; means for providing said axially inserting means; means for rotating said platform between closed and open positions, said second assembly being exposed externally of said enclosure in said open position, and said second assembly being within said enclosure in said closed position; and means for detachably connecting said second assembly to said powering means.
Claim 7
Dependent Claim
102 words
A coil assembly apparatus, which comprises: an enclosure; a mounting platform rotatably mounted of said enclosure; means for axially inserting a prewound coil into the core of a dynamoelectric machine, said means comprising a first assembly mounted above said platform and a second assembly mounted below said platform; means for providing said axially inserting means; means for rotating said platform between closed and open positions, said second assembly being exposed externally of said enclosure in said open position, and said second assembly being within said enclosure in said closed position; and means for detachably connecting said second assembly to said powering means.
Claim 8
Dependent Claim
75 words
The apparatus of claim 5 wherein said means for detachably connecting said second assembly to said powering means comprises a socket having an opening therein and a shaft with a disc head projecting radially therefrom, adapted for detachably mounting to said socket, said socket being operatively connected to one of said powering means and said second assembly, said shaft and head being operatively connected to the other of said powering means and said second assembly.
Claim 9
Dependent Claim
