Changer device for clamping heads

A changer device for clamping heads, the changer device comprising the following features:

• the changer device is configured for inserting a clamping head into a chuck and/or for removing the clamping head from the chuck, wherein the clamping head has a plurality of clamping jaws which are repositionable relative to one another in a radial direction, the changer device forcibly acting on the clamping jaws to displace the clamping jaws towards or away from one another in the radial direction;
• the changer device comprises a base;
• the changer device comprises a plurality of pivoting elements which are articulated so as to be pivotable on the base, each pivoting element comprising at least one engagement portion for forcibly acting on the clamping jaws;
• the changer device comprises a coupling transmission, the coupling transmission comprising at least one coupling tab for each said pivoting element, each coupling tab being attached so as to be pivotably movable on the respective pivoting element, wherein the pivoting elements in terms of movement thereof in relation to the base are coupled by way of the coupling tabs;
• the changer device comprises a handle which is movable for a purpose of simultaneous repositioning of the pivoting elements in relation to the base;
• and
• the handle is configured so as to be locationally fixed in relation to one of the coupling tabs such that a pivoting movement of the handle directly causes pivoting of said one coupling tab and indirectly causes pivoting of at least one further coupling tab such that a pivoting movement of the pivoting elements and of the engagement portions thereof is caused.
