In a pallet (31) for the seating of interchangeable clamping jaws (21) lockable to base jaws (4) of a chuck (1) the clamping jaws are inserted, for their retention in radially oriented, open-faced recesses (32) of the pallet (13). In the pallet, on both sides of each recess (32) one or more clamping bolts (33) are provided, each of which is arranged so as to be movable within limits and to which a pressure can be applied. By means of the bolts, the interchangeable clamping jaws (21) can be locked in a defined position in the pallet (31) and unlocked for their removal. This makes it possible to insert the interchangeable clamping jaws (21) without problems into the recesses (32) of the pallet (31) and also to remove them from the pallet without having to guide the interchangeable clamping jaws (21) laterally and without their jamming between guide surfaces. Rather, centering and fixing of the interchangeable clamping jaws (21) takes place automatically, when they are in a predetermined end position. |
