ALIGNING DEVICE FOR WORKPIECES ON MACHINE TOOL TABLES

摘要

An aligning device for workpieces on machine tool tables. The aligning device has a housing having a cover plate and a lifting ram vertically movably mounted on the cover plate and protruding out of the upper surface thereof. A pressure plate is arranged within the housing and engages the lower end of the lifting ram and has a planar wedge surface at its underside. A wedge is mounted in the housing below the lifting ram and is capable of sliding transversely of the lifting ram between the pressure plate and a base plate of the housing. The wedge has at its top surface a wedge surface which is parallel to the first-mentioned wedge surface and a planar under surface parallel to the interior surface of the base plate. Roller bearings or ball bearings are arranged between the wedge surfaces and between the underside of the wedge and the interior face of the base plate. A set screw is mounted in the lateral wall of the housing and engages the wire end of the wedge and is adapted to move same transversely of the lifting ram.
