摘要： The invention relates to a chuck (1) for a machine tool for machining a tubular workpiece which rotates about a rotational axis (4) that coincides with the centre of the chuck, comprising at least two chucking slides (7a, b, c) that are designed to be positionable radially with respect to the rotational axis (4) in order to release and chuck the workpiece, are arranged on the end side of and in a manner distributed uniformly around the circumference of a chuck head plate (2), and bear chucking jaws (8a, b, c). The operating characteristics for the central and/or balancing chucking of a tube are improved when each chucking slide (7a, b, c) is assigned firstly transverse slides (9a, b, c) which are provided tangentially to the rotational axis (4) in the head plate (2), are acted upon by an adjusting means and have a slide block (11) formed as a rack (12) on a longitudinal side, and secondly separate toothed wheels (19a, b, c) which mesh with the racks (12), wherein each chucking slide (7a, b, c) is provided on its underside with a driving claw (17) which, in order to deflect the movement of the transverse slide (9a, b, c) in an adjusting movement, extending at right angles to the rotational axis (4), of the chucking slide (7a, b, c), is in engagement with a slot-like guide groove (16) provided in the slide block (11) of the transverse slide (9a, b, c), and wherein the toothed wheels (19a, b, c) are assigned a coupling pinion (20) that can be engaged and disengaged axially with respect to the rotational axis.

摘要： A work grip device which is installed to a tool turret, and a transfer method of a work in an inner portion of a lathe turning machine using the grip device are provided without arranging a drive source in the work grip device, and an electric wiring and a hydraulic pressure piping to a turret which moves and index rotates. The work grip device is provided with an opening and closing jaws which are driven so as to be opened and closed on the basis of a rotation of a tool motor. A holder of the work grip device is provided with an input shaft which is connected to a tool drive shaft within a turret head by the same structure as a rotary tool at a time of being attached to the tool turret, and is provided with a motion converting mechanism converting a forward and reverse rotation of the input shaft into an opening and closing motion of the opening and closing jaws of the grip device which is provided in the holder.
