Patent GB-479179-A (GB)
Title: A device for dressing grinding wheels with shouldered profile
IPC: B24B53/08
Filed: 1937-05-18
Abstract: 479,179. Trueing grinding-wheels FORTUNA-WERKE SPEZIALMASCHINENFABRIK AKT.-GES.. and DANNER. H. May 18, 1937, No. 13814. [Class 60] In a device for dressing shouldered profile grinding-wheels having a dressing tool operated hydraulically, the tool is guided by a fixed template associated with a control rail connected to a slide carrying the tool, the rail effecting interruption of the supply of pressure fluid to the hydraulic means for moving the slide when a guide pin provided on the tool holder reaches a shoulder of the template. The dressing diamond is mounted in a holder 2 adapted to be moved in guides 14 radially relatively to the wheel by means of a rack and pinion drive 18. The guides 14 are formed in a slide 7 which is movable axially along the wheel in guides 6 by means of a fluid operated piston 5 and rod 9. The position of the tool radially of the wheel is controlled by means of a guide pin 20 carried by an arm 21 of the holder 2 and resting on a template 19 secured to the frame 1 of the device. Pressure fluid is supplied to the cylinder 4 through a rotary control valve 13 operated by a lever 25 having a manually operable arm 26 and a shorter arm adapted to be operated by a rod 32. One end of the rod is formed as a tooth 35 and is normally pressed by a spring 34 against a guide rail 22 carried by the slide 7 in which it is accurately adjustable by a screw so that at the instant the guide pin 20 reaches a shoulder of the template, the tooth 35 enters a notch such as 23 in the rail. The rod then rotates the valve 13 to cut off the fluid supply and so stops the axial traverse of the tool which is then fed radially of the wheel by the rack and pinion device 18 until the pin 20 again rests on the template. The axial traverse is restarted by operating the arm 26. In order to maintain a constant traversing speed of the tool over the grinding wheel profile, the actual axial speed must be reduced while the tool is on a frustoconical part of the surface. This is effected by means of a notch 39 in the guide rail of such a depth as to cause the valve to reduce but not to cut off the fluid supply. A reversing valve 12 may be operated manually or automatically by means of abutments on the slide 7.
