Abstract
It is an object of the present invention to provide a hydraulic-free automatic swiveling turret apparatus which can easily ensure a swiveling function that is smooth and superior in terms of durability using a simple construction without any need to install a hydraulic pressure reducing mechanism requiring complicated design and control. The present invention provides an automatic swiveling turret apparatus for a machine tool comprising a wedge mechanism (13) which is constructed so that a resistance reducing member (9) that reduces the sliding frictional resistance during swiveling of the turret (3) is disposed on the inside surface part of the sliding movement gap (7) that abuts when the anchoring and fastening of the clutch device (4) are released by causing the sliding of the turret (3) in the axial direction as a result of allowing the inflow of air into the clutch release pressure chamber (6), and in which the turret (3) in a working position that does not allow swiveling, which is anchored and fastened by the clutch device (4), is anchored in a wedged fashion and held as a result of return sliding.
