ABSTRACT:
We are dealing with a mechanism for clamping a second machine part 4 which is supported movably with respect to a first machine part 2. A clamping bar 28, which extends in the direction of movement is arranged on the second machine part 4, on which clamping bar can be clamped a clamping member 32 which is supported freely movably in directions transverse to the direction of movement of the first machine part, but otherwise clearance free. Since the clamping member 22 is as a whole freely movable in directions transverse to the direction of movement, no reactive forces whatsoever are created in the direction of movement during the clamping operation.
The inventive clamping mechanism is preferably used in feed-movable spindle sleeves (tail spindles) in order to assure a secure clamping in an axial direction and in a peripheral direction, without producing forces which act transversely to the spindle axis.
