摘要： The invention relates to an indexing chuck (1), comprising a chuck body (2), in which an accommodating opening (3) is incorporated; comprising a pivoting ring (5) inserted in the accommodating opening (3) of the chuck body (2), on which pivoting ring at least three clamping jaws (6) that can be advanced radially perpendicularly to the longitudinal axis (4) of the chuck body (2) are supported; comprising an advancing device (8), which is inserted into the pivoting ring (5) and by means of which the clamping jaws (6) can be moved synchronously; comprising two pivot pins (11, 12), which are supported in the chuck body (2) and which form a pivot axis (13), wherein the advancing device (8) of the at least three clamping jaws (6) is formed by a synchronizing ring (33), which is supported so as to be movable parallel to the longitudinal axis (4) of the chuck body (2) in the pivoting ring (5), a driving surface (36) extending at an angle to the longitudinal axis (4) of the chuck body (2) is fastened to the synchronizing ring (33) in the region of the respective clamping jaw (6), and a contact surface (37) is provided on the respective clamping jaw (6), which contact surface interacts with the driving surface (36) of the synchronizing ring (33) in such a way that the clamping jaws (6) are moved radially out of the pivoting ring (5).
