Abstract
933,453. Lathes; machine details. H. ERNAULT-BATIGNOLLES. June 13, 1961 [July 21, 1960], No. 21370/61. Class 83 (3). A controlled fluid-pressure feed movement for the slide of a lathe or other machine has means for maintaining the feed movement proportionate to a rotating part such as the work spindle of the lathe. A lathe saddle 1 is rigidly connected to the differential piston 3 of a piston and cylinder actuator supplied with fluid pressure from a pressure source 7 and exhausting through line 14 to a reservoir 15. The actuator is controlled by a piston valve 12 which is rigidly connected to a worm 20. In addition to its sliding control movements the valve is rotated by gears 21, 22 from a gear-box shaft 27, the input drive of which is from the lathe spindle by a belt. The lathe saddle is provided with a screw or rack 46 which engages a gear 39 carried by a shaft 38 supported on a fixed part of the machine. The shaft 38 may be clutched to a shaft 36 carrying a worm gear 33 meshing with the worm 20 connected to the valve 12. The feed movement in either direction is thus controlled to " follow " the speed chosen for shaft 27. The screw 46 may be hand-rotated. The drive from the gear-box 27 is through an electromagnetically operated clutch and brake 26, 29 respectively. Electromagnetic clutch arrangement 41, 37 enables the saddle to be driven at high speed for quickreturn movements. An adjustable stop bar is provided to cut-off the feed movement at the end of predetermined strokes.
