DEVICE FOR CLAMPING A WORKPIECE ALONG A ROTATABLY DRIVEN LONGITUDINAL AXIS

摘要

The device is constructed with a tensioning spindle ( 12 ), a counter-holder ( 14 ) and a carrier ( 30 ), at least the tensioning spindle ( 12 ) being mounted such that it is rotatable about the longitudinal axis, and the carrier ( 14 ) being fixed to the tensioning spindle ( 12 ) and, when the workpiece ( 50 ) is clamped between the tensioning spindle ( 12 ) and the counter-holder ( 14 ), being capable of being brought into engagement with the workpiece ( 50 ) in such a way that it transmits a rotary movement of the tensioning spindle ( 12 ) to the workpiece ( 50 ). The device furthermore provides for the carrier to have a spring element ( 30 ) which can be coupled to the workpiece ( 50 ) under prestress to transmit a torque.
