1,226,237. Grinding; work-holders. MICROMATIC HONE CORP. 7 March, 1969 [12 June, 1968], No. 12163/69. Headings B3B and B3D. A work-holding fixture comprises an elongated tubular body 20, an annular resilient member 28 within the body, an annular collet 30 secured within and abutting the inner surface of the annular resilient member, and means 60 for delivering fluid pressure into the tubular body to move the resilient member against the outer surface of the collet to move the collet into gripping relationship with a workpiece. The tubular body may be held on the bed 12 of a honing, abrading or boring machine and is adjustable on the bed by a pair of cams 18. The inner surface of the body 20 is formed with a recess 22 defining top and bottom shoulders 24, 26 against which the annular resilient member 28 is held by locators 38, 50. The latter also axially locate the collet 30 and have projections 36, 42 engaging recesses 31, 33 in the collet. Slots 32, 34 extend from the recesses to form panels 35 in the collet which grip a workpiece when fluid pressure is supplied through a pipe 60 to the recess 22 to urge the resilient member 28 against the collet. The workpiece is removed from the collet by an ejector 52. |
