ABSTRACT

A clamping device for holding, for example a work piece in a machine tool, has
a housing with a cylindrical bore and a clamping piston with a dead-end cavity
axially slidable in the housing. A clamping lever extends through a
ball-bushing with an inner end into the dead-end cavity of the piston and with
an outer end carrying a clamping head out of the housing. The inner piston end
has a first slanted surface that cooperates with a correspondingly slanted
second surface rigidly held in the cavity of the piston. A guide and stop pin
also rigidly mounted in the piston cavity cooperates with a recess in the
clamping lever to guide an axial movement of the lever relative to the piston
and to facilitate a pivoting movement of the lever about the center of the
ball-bushing, but simultaneously preventing or stopping a relative rotation
between the piston and the lever. Such a structure can be adjusted to apply
the clamping force in any direction in a plane extending perpendicularly to
the longitudinal axis of the clamping device.
