Abstract
1,069,174. Grinding. MICROMATIC HONE CORPORATION. Oct. 11, 1965 [Dec. 23,1 964], No. 42939/65. Heading B3D. Apparatus for finishing parallel faces of a workpiece rotatable about an axis perpendicular to the faces comprises: (a) a housing mounted for reciprocation in a plane perpendicular to the axis, the housing including at least one pair of parallel spaced longitudinally extending guide surfaces; (b) a pair of abrasive stones carried by the housing for movement therewith; and (c) means carried by the housing and movable along the guide surfaces for moving the stones into engagement with a workpiece face. The disc 14, Fig. 1, of a disc brake is supported between fixtures, one of which is rotatably supported by an adjustable hand wheel 16 and the other is carried by the shaft of an electric motor 18 serving to rotate the disc. Two opposing pairs of abrasive tool assemblies are mounted in a tool housing 23 vertically reciprocated on a fixed frame 13 by an hydraulic cylinder 15. Each tool assembly comprises an abrasive stone 33 fixed to a holder 35, Fig. 3 (not shown). Each holder has longitudinally spaced tapered rear faces 37 engaging tapered faces 39 on a plate 41 slidable in a groove in the tool housing. To advance the stone into contact with the workpiece, pressure fluid is admitted through inlet 51 and acts on a piston 43 to move the plate 41 downwards. To remove the plate 41 upwards, pressure fluid is admitted through inlet 63 and acts on a piston 55, the stone being retracted from the workpiece by leaf springs 65. In operation, the workpiece is mounted between the fixtures and the motor 18 actuated to rotate the workpiece. With the stones retracted the tool housing 23 is lowered. The stones are advanced into contact with the workpieces and the housing reciprocated rapidly to produce a random surface grain structure or slowly to produce a concentric surface grain structure. The operation may be terminated by a timer or by a gauging device. In a modification. Fig. 7 (not shown), the tool housing 23 is reciprocated through a connecting rod 75 by a crank-pin 77 on a disc 73 driven by a variable speed motor. The workpiece 14 is raised into finishing position by a lift 83 hydraulically or otherwise actuated, and having a concavity 85 to cradle the workpiece. One fixture 87 is reciprocable by a fluid motor 89 or a hand wheel and has a tapered end portion 91 engaging a central opening 93 in the workpiece to raise it clear of the lift and press it into engagement with the other fixture. The workpieces may be handled automatically.
