Tool holder for machine tools and tool system for machine tools

摘要

The invention provides a tool support for machine tools comprising a base unit, a holding member arranged on the base unit and two supporting surfaces extending at an acute angle to one another arranged on the holding member for supporting a tool holder in first and second supporting areas. A clamping device acts on a clamping member of the tool holder such that the tool holder acts upon the supporting surfaces with the two supporting areas. The clamping element may be mounted in the holding member for rotation about an axis and bear a wedge surface movable around the axis for acting on the clamping member. The wedge surface of the clamping element may engage over the clamping member proceeding from an insert position during the rotation of the clamping element in a first direction of rotation and displace the clamping member increasingly in the clamping direction.
