ABSTRACT:
An exchange device for grip heads comprising a plurality of clamping jaws, consisting of a carrier plate having a borehole. Pivoting arms are axially staggered in relation to the carrier plate and are concentrically arranged in relation to the borehole. The pivoting arms are articulated by a joint in such a way that they can be pivoted in a plane containing the axis of the borehole. The pivoting movement is thus carried out radially in relation to the axis of the borehole. Coupling elements are arranged on the pivoting arms, by which the exchange device can be coupled to the clamping jaws of the grip head and detached from the same.
