Changer device for clamping heads

A changer device for a clamping head, the changer device being configured for inserting the clamping head into a clamping chuck and/or for removing the clamping head from the clamping chuck, wherein the clamping head has a plurality of clamping jaws which can be mutually displaced in a radial direction and which can be mutually subjected to force by the changer device toward one another or away from one another in the radial direction, the changer device comprising:

• a base;
• a plurality of adjusting elements which are movably attached to the base in a pivotable and/or translatory manner and which in each case have at least one engagement portion for application of force onto the plurality of clamping jaws;
• and
• a drive member which is rotatably movable about a central axis relative to the base;
• the drive member being coupled by gear mechanism to the plurality of adjusting elements so that by a rotational movement of the drive member the plurality of adjusting elements can be jointly moved toward one another or away from one another;
• wherein the gear mechanism has a sliding sleeve which is attached to the base in a manner which is translatory movable but fixed in terms of rotation and which is coupled to the drive member by a treaded drive;
• and
• wherein the sliding sleeve is coupled to the plurality of adjusting elements.
