Abstract
967,170. Machine tool details. ALFRED HERBERT Ltd. Dec. 14, 1960 [Dec. 14, 1959], No. 42360/59. Headings B3B and B3T. In a machine tool, means for stopping an electrically-driven slide 5 comprises a first plunger 8 which when depressed slows the travel of the slide and a second plunger 10 which, when depressed on further movement of the slide, stops the slide. The turret slide 5 carries an adjustable stop 4 to engage an electrically-conductive plunger 3, insulating sleeves being indicated by thick-band shading. When the plunger 3 is pushed against the plunger 8 a circuit is completed by way of members 15, 14, 13, 12, 8, 3, 2 to reduce the speed of the slide. Upon further slide movement, the plunger 8 engages the plunger 10 and a second circuit is completed through members 22, 10, 8, 3, 2 to stop the slide. When the slide is returned to its initial position, a further stop depresses a plunger 25 to complete a circuit through members 2, 25, 26, 27, 10, 22 to stop the slide, there being an over-run buffer 29. In a modification, a cross-slide 31, Fig. 2, has a projection 37 which can engage adjustable nuts 34 to move a plate 43 against a plunger 44 completing a circuit through members 48, 44, 32, 32, 30 to reduce the speed of the slide. The slide movement is stopped when the plunger 44 is pushed against a block 46 to complete a further circuit. Reduction of speed may alternatively be effected by an adjustable stop 39 depressing a plunger 42, the circuit then being completed through the slide itself. On the return movement, the slide engages nuts 35 and causes a disc 55 to engage a collar 54 to complete a circuit to stop the slide, a spring 56 serving as a buffer. Low currents are used in all the circuits, amplifying means being provided if necessary for operating electric motors.
