Abstract
837,262. Trueing grinding wheels. HACK, K. July 16, 1958 [Aug. 14, 1957], No. 22743/58. Class 60. Apparatus for trueing the grinding discs 4, 4a of a spring-end grinding machine comprises members 24, 24a associated with trueing tools 3, 3a for sensing the amount of wear thereof, and means automatically operated from the measurement values of the sensing members for an adjustment of the trueing tools and at least one of the grinding discs corresponding to the amount of wear. The trueing tools consist of wheels 3, 3a carried on a support 1 which can be vertically moved in one direction or the other to bring the respective trueing wheel into operative position by a hydraulic piston-and-cylinder device 5, 6, the cylinder of which has its ends selectively connected to a pump 10 by a switch 9 : in an alternative arrangement, the wheels may be independently adjustable on the support. The sensing members 24, 24a, which may be mechanical, electrical or photo-electrical, are carried at one end of levers 26, 26a, pivoted to the support 1 and having their other ends arranged to contact adjustable stops 14, 15 on a rod 16 resiliently supported by springs 17, 18 ; fine adjustment means 20 are provided on the stops. When the switch 9 is moved to the position shown, fluid pressure is applied to the device 5 to move the trueing wheel 3a to its operative position until the lever 26a contacts the stop 15 to displace the rod 16 against the springs, a fork switch 19 thus being moved to close a valve 13, preferably a conical valve, to arrest the piston 5 and maintain the wheel in its operative position. As the trueing wheel wears, the sensing member 24a is displaced and the end of the lever 26a moves away from the stop 15, the rod then moving under the pressure of the springs 17, 18 to cause the switch 19 to open the valve 13 and the device 5, 6 actuated to adjust the wheel 3a until the lever 26a again abuts the stop 15. A similar arrangement for the lower trueing wheel 3 is effected by the member 24, lever 26 and stop 14 when the switch 9 is in its other position. A further sensing member 27, which may be mechanical, electrical or optical, is spring-loaded or weighted into contact with the trueing wheel 3a and is carried on a lever 28 which, when the wheel wears, is tilted to actuate a switch 30 controlling the supply of hydraulic fluid from a pump 31 to a piston-and-cylinder device 33, 36 ; pressure to one side or the other of the piston moves the disc 4a and the bearing 29 for the lever until the disc is aligned with the trueing wheel. A similar arrangement may be provided for the lower disc 4 but preferably this disc with the driving motor 37 remains stationary, and the workpiece guide 21 and the rod 16 with the stops 14, 15 which are connected by rods 22, 23 adjusted by the apparatus or by hand or remote control. The hydraulic system may be replaced by an electrical, mechanical or electro-magnetic arrangement. The period of trueing may be automatically determined by an apparatus measuring or sensing the workpieces.
