US 5,845,553 A · Stator lamination jig system

Abstract

The invention is a stator lamination jig system which comprises a centrally located spindle and a support for a stator lamination having a plurality of holes therein. The support is rotatively-mounted on the spindle for driving the lamination during a notching operation. A plate is included to secure the lamination on the support and a non-rotatable ejector is located below the support which has a lowered position and a raised position. An ejection cylinder is seated upon the ejector which is shaped and positioned to extend through holes in the support. The invention also comprises a cylinder connected to the ejector for driving the ejector. When the cylinder is actuated upwards, the ejector is in a raised position which urges the ejection cylinder through the holes in the support to cause the lamination to be released from the jig.

Dependent claims

A method of automatically securing and releasing stator laminations from a jig comprising the steps of:

placing a stator lamination on a substantially circular drive plate of said jig, said drive plate including plurality of through holes arranged about an outer periphery thereof, each of said holes receiving an ejection plug therethrough;
securing said lamination with a hold-down plate;
incrementally rotating said drive plate with an indexing motor, such that said ejection plugs side over a stationary ejection plate;
subsequent to each of said incremental rotations, forming a notch on said lamination;
removing said hold-down plate from engagement with said lamination;
and
displacing said ejection plate upwardly to urge said plurality of ejection plugs upwardly through said holes, thereby causing said lamination to become disengaged from said drive plate.
