# Clamping device for securing a first component, such as a tool, to a second component

## 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.
