Clamping head arrangement

Abstract

The invention relates to a clamping head arrangement, in particular for clamping a drill rod element, having a plurality of clamping jaw elements, each of which has a clamping surface which is designed in particular for clamping contact with a contact side of the drill rod element, and a main body with guide tracks, along which the clamping jaw elements are displaceably mounted, wherein the guide tracks are angled to a centre axis of the clamping head arrangement, so that displacement of the clamping jaw elements along the guide tracks causes axial and radial displacement of the clamping jaw elements with respect to the centre axis. According to the invention it is provided that the clamping jaw elements are each designed with a cylindrical or partially cylindrical guide body, and that the guide tracks in the main body are formed as partially cylindrical guide channels, in each of which a clamping jaw element with the cylindrical or partially cylindrical guide body is displaceably mounted.
