Abstract

1360123 Adjustable ecceritrics WERKZEUGMASCHINENKOMBINAT "7 OKTOBER" BERLIN VEB 8 May 1972 21380/72 Heading F2K [Also in Division B3] A means for imparting variable stroke to the reciprocating tool slide of a machine tool, e.g. in a grinding machine, comprises a shaft 5, driven by an infinitely variable speed motor (not shown) through pulley 7 and having a helical thread on which an eccentric nut 1 is mounted. About this nut 1 is an external eccentric 2, affixed to a wheel 3 which has teeth engaging with teeth on a member 4 which rotates with shaft 5. The shaft 5 is movable axially in one direction by a piston 10, and in the other by a piston 9. Axial movement of the shaft 5 causes nut 1 to rotate by virtue of the helical thread, relative to both the shaft and the external eccentric 2, varying the eccentricity of the combination of eccentrics as sensed by one end (roller 15) of a lever 14 whose other end controls movement of the tool slide 20 (permanently biased by piston 12). The lever is pivoted in a housing 13 which can be rocked (on bearings 26, 28) about the axis of shaft 5 by a cam 17 which in changing the pivot position alters the range of movement of the tool slide 20. The piston 9, which is adjustable through a screw 8 to control the maximum eccentricity is permanently biased towards the zero eccentricity position of the device, so that this is attained whenever no pressure fluid is supplied to piston 10.
