Abstract: A changer device for a clamping head having a base and pivoting elements pivotably articulated on the base and which in each case possess at least one engagement portion for impinging clamping jaws of the clamping head with a force. The changer device has a coupling transmission which per pivoting element possesses at least one coupling tab attached so as to be pivotably movable on the respective pivoting element. The changer device has a handle which for the purpose of simultaneous repositioning of the pivoting elements in relation to the base is movable in a relative manner. The handle is locationally fixed in relation to one of the coupling tabs such that a pivoting movement of the handle directly causes pivoting of the coupling tab and indirectly causes pivoting of the further coupling tab such that a pivoting movement of the pivoting elements and the engagement portions is caused.

Abstract: A replacement device for clamping heads comprises a plurality of clamping jaws and is provided with pivoting parts, which are pivotably mounted on a carrier. The pivoting parts extend essentially in the axial direction of the device and can engage in holes on the clamping jaws. A radially active force applying device pushes the pivoting parts outwards, causing the clamping jaws connected thereto to be pressed together. In this way, the clamping head can be used in a housing or a machine-tool.

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.

Abstract: 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.
