Abstract
825,242. Grinding. MALCUS HOLMQUIST A. B. May 29, 1957 [June 15, 1956], No. 17089/57. Class 60. [Also in Group XXXV] A device for automatically controlling the distance between the grinding wheel and the counter support in centerless grinders of the kind in which the work pieces are fed substantially parallel to the axis of the grinding wheel and in which a control device is operatively connected through contacts and relays to a gauging device disposed after the grinding wheel, considered in the direction of feed of the workpieces and adapted to measure the diameter of the ground workpieces and to check such diameter with regard to maximum and minimum sizes, is characterised by a switch disposed after the grinding wheel and adapted for actuation by one of the workpieces to render effective the circuit between the gauging device and the control device only when no gap in a workpiece or between two workpieces occurs at the gauging device. A gauging device 4 gauges the diameter of workpieces 2 after they have left the grinding throat between a grinding wheel 3 and a regulating wheel (not shown) and, through a relay 12, solenoids 13, 14 and pawl and ratchet mechanism 15, 16, 19 increases or decreases the distance between the grinding and regulating wheels as necessary to correct for undersize or oversize. A normally open switch 10 in circuit with the relay normally renders it inoperative. The switch 10 is closed by engagement of a lever 11 by the workpiece 2<SP>1</SP> ahead of the workpiece 2 being gauged, and is allowed to open when the workpiece 2<SP>1</SP>. falls down the shoot. Thus the control responds only to gauging of a short length of its workpiece free from discontinuities. If the workpieces continue in a straight line, the lever 11 is spaced from the device 4 by a distance equal to the length of a workpiece.
