Wedge removal saw apparatus for a dynamoelectric machine

A wedge removal saw apparatus for a dynamoelectric machine, said machine comprising a stator core including a plurality of thin metallic laminations stacked to form said stator core, said stator core having a plurality of slots therethrough spaced at equal intervals around the inner diameter of the core, winding coil means positioned in said slot, each of said slots at one end thereof proximate the inner diameter of said stator core forming an air gap for magnetic flux, said stator core along opposite sides of each of said slots proximate said air gap end having a groove of predetermined shape positioned a predetermined distance from said air gap end of each of said slots, a plurality of relatively thin non-metallic wedges engageable in said grooves for maintaining said winding coil means in position in said slots, said apparatus comprising:

• (a) circular saw means for sawing each of said non-metallic wedges into a plurality of wedge sections, said saw means including a base member means affixed to said saw means;
• (b) guide means for supporting and guiding said circular saw means along said wedges, said guide means comprising guide rod means, support means for supporting said guide rod means;
• said support means comprising channel member means of predetermined size, said channel member means having a central member and lip members positioned on opposite sides thereof forming a channel of predetermined size on the bottom portion of said channel member means, clamp means for clamping said support means to said stator core grooves, said clamp means comprises groove engagement means housed substantially within said channel of said channel member means, said groove engagement means comprises a fixed groove engagement member mounted to said channel member means proximate one of said lip members, said fixed groove engagement member having a pair of first groove engagement jaw members, each of said first jaw members having a first groove engagement portion shaped to engage a first of said groove, on one of said opposite sides of one of said slots, and first groove engagement jaw members positioned a predetermined distance from said saw blade so as to engage said first groove of one of said slots next to another of said slots containing said wedge means to be sawed, said base means riding on said guide rod means;
• and
• (c) power supply means for providing power to said circular saw means, whereby when said guide means is positioned such that said clamp means may engage the stator core grooves in one of said slots next to another of said slots containing wedges to be sawed, when said saw means is energized and said wedges are sawed, a plurality of wedge sections are removed from said grooves of said other slot.
