Clamping element for clamping workpieces in a flexible position

Abstract

A clamping element is provided for clamping workpieces in a flexible position with hydraulically actuated clamping jaws, which can be moved to the workpiece and can be fixed by a clamping insert (2; 30) guided in a housing (1; 29). The clamping insert is provided with an internally located piston (3), which is guided slidingly. Clamping jaws (20; 31) as well as a clamping lever (11), which is connected to the piston via a connecting rod (8) in an articulated manner, are associated with the clamping insert. The clamping operation moves the piston upward and presses the clamping lever onto the workpiece (25). The resistance originating from the workpiece brings about the stopping of the clamping lever and at the same time continues to raise the clamping insert, as a result of which the clamping jaws come into contact with the workpiece under the workpiece and firmly connect the workpiece to the clamping insert.
