AXIALSPANNFUTTER

摘要

In an adjustable chuck arrangement a carrier is axially displaceable within a bell-shaped base and restraining elements are hinged to the carrier and extend outwardly through openings in a supporting plate attached to the base. When the carrier is displaced axially relative to the base, the restraining elements are also displaced in the axial direction. Further, the surfaces of the restraining elements, where they pass through the supporting plate, are shaped so that as they move axially they contact the surfaces of the openings in the supporting plate and pivot about their hinged connections. Clamping devices secure the restraining elements to the carrier and provide the hinged connections for the elements. The position of the clamping devices in the carrier can be reversed through 180 DEG for adjusting the location of the restraining elements relative to the axis of the chuck.
