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.
L'invention concerne un dispositif d'échange (30) de têtes de serrage (20) comportant plusieurs mâchoires de serrage (21), composé d'une plaque support (31) présentant un alésage (32). Des bras pivotants (33) sont disposés de manière axialement décalée par rapport à la plaque support (31), et concentrique par rapport à l'alésage (32). Lesdits bras sont articulés par l'intermédiaire d'une articulation (34) de manière à pivoter dans un plan contenant l'axe d'alésage (37). Ainsi, le mouvement de pivotement s'effectue de manière radiale par rapport à l'axe d'alésage. Lesdits bras pivotants (33) comportent des éléments de couplage (35) permettant de coupler et de détacher le dispositif d'échange (30) par rapport aux mâchoires de serrage (21) de la tête de serrage (20).
