    摘要： © A chuck especially for a machine tool that operates in a universal manner as a two, three or four jaw chuck. The chuck (10) comprises four jaws (25) arranged in diametrically opposed pairs on the front face (12) of the chuck (10). The chuck (10) including drive pinions (36, 37) that drive a scroll (39, 239) that co-axially carries a differential gear train including a pair of differential gears (50, 51) one driving one pair of jaws (25) and the other driving the other pair whereby the differential gear train apportions the drive between the pair of jaws so that one pair may move independently of the other pair.

    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： The invention relates to a clamping device (01) for use on a lathe, comprising a plurality of basic clamping supports (06), which can be moved in a stellar formation in relation to an axis of rotation and on each of which a clamping jaw (11) for clamping workpieces can be attached, wherein the basic clamping supports (06) can be adjusted simultaneously by means of an adjusting drive (21, 36) of the clamping device (01). According to the invention, at least two basic clamping supports (06) are coupled directly or indirectly to one another by means of an outer rocker (15), wherein, at least in the middle of the adjusting path, a limited inward movement of a basic clamping support (06a, 06c, or 06b, 06d) leads to a pivoting of the outer rocker (15a, 15c) and an outward movement of the other coupled basic clamping support (06b, 06d, or 06a, 06c).

    摘要： An equalizing chuck assembly (10) for heavy duty application includes a chucking assembly having a plurality of rocker arms (18) operably connected to an actuator (14) by a plurality of toggle links (60). Jaw members (20) are disposed on one end of the rocker arms (18) and a counterweight (22) is disposed on an opposite end of the rocker arms (18). The equalizing chuck assembly (10) utilizes a plurality of equalizing plates (52) interconnected between the actuator (14) and the rocker arm (18) to provide a degree of adjustment to accommodate eccentricities within the workpiece to be held by the chucking assembly (10).
