Abstract

This fixture permits electrical discharge machining electrodes which are bent or otherwise misshapen to be adjustably aligned with the primary axis of the tool central shaft while also providing a vent for the machining waste products. The threading electrode 10 with its extension 10A for threading by electrical discharge is threaded into the lower frame 11. This frame 11 has a ball extension 11A which coacts with a spherical socket 12A in a next higher level frame 12 to form a ball and socket joint. Tilt-adjusted screws 13 secure the ball in socket and, by differential tightening, permit the lower frame 11 to be tilted with respect to frame 12. The second frame 12 is secured to a double-flanged third frame 14 by the screws 13 which fit in enlarged holes in frame 14 so as to permit eccentric movement between frames 12 and 14.

Misalignment Correction Fixture for Electric Discharge Machinery Tools

This fixture permits electrical discharge machining electrodes which are bent or otherwise misshapen to be adjustably aligned with the primary axis of the tool central shaft while also providing a vent for the machining waste products. The threading electrode 10 with its extension 10A for threading by electrical discharge is threaded into the lower frame 11. This frame 11 has a ball extension 11A which coacts with a spherical socket 12A in a next higher level frame 12 to form a ball and socket joint. Tilt-adjusted screws 13 secure the ball in socket and, by differential tightening, permit the lower frame 11 to be tilted with respect to frame
12. The second frame 12 is secured to a double-flanged third frame 14 by the screws 13 which fit in enlarged holes in frame 14 so as to permit eccentric movement between frames 12 and 14. The frame 12 is hat-shaped with an upstanding cylindrical portion extending into an enlarged bore in the double- flanged frame 14, which frame has radially extending screws 15 for moving the frame 12, bottom frame 11, and tool 10 eccentrically with respect to frame 14. Frame 14 is integral with frame 16 which has the internal bore 16A to receive the grooved cylinder 17 with "O" ring seals therebetween. A flushing port 16B communicates with the bore 16 and cylinder 17 into which the tubular tool 10 is secured. By this fixture, any misalignment of the tool 10 can be correct...
