Axle Arrangement for Mounting a Tool or a Workpiece and Method for Operating the Axle Arrangement

Axle arrangement for mounting a tool or a workpiece comprising:

• a base body;
• a receiving unit supported by means of a swivel bearing assembly on the base body so as to be rotatable about a longitudinal axis (L), the receiving unit including a receiving sleeve with a receiving opening;
• a gripper actuating element that can be slid in the receiving sleeve along the longitudinal axis (L), the gripper actuating element having on one end, a gripper unit for the tool or the workpiece, said gripper unit being arranged at least in part in the receiving opening;
• a pretension unit that is disposed to generate a pretension force acting in longitudinal direction parallel to the longitudinal axis (L) between the gripper unit and the receiving unit in order to force the gripper unit into a clamping position;
• an actuatable release unit that is disposed to slide the gripper actuating element with the gripper unit counter the pretension force of the pretension unit relative to the receiving sleeve in order to move the gripper unit out of the clamping position into a release position;
• and
• a support unit that is arranged on the base body and that includes an auxiliary bearing and an actuating unit for switching the support unit between a support state and a rest state, wherein the actuating unit is disposed to generate a pressing force in the support state and press the auxiliary bearing against the receiving sleeve.
