Exchange device for grip heads comprising a plurality of clamping jaws

摘要

The invention relates to an exchange device (30) for grip heads (20) comprising a plurality of clamping jaws (21), consisting of a carrier plate (31) having a borehole (32). Pivoting arms (33) are axially staggered in relation to the carrier plate (31) and are concentrically arranged in relation to the borehole (32). Said pivoting arms are articulated by means of a joint (34) in such a way that they can be pivoted in a plane containing the axis (37) of the borehole. The pivoting movement is thus carried out radially in relation to the axis of the borehole. Coupling elements (35) are arranged on the pivoting arms (33), by which means the exchange device (30) can be coupled to the clamping jaws (21) of the grip head (20) and detached from the same.
