    摘要： A compact oldham-type floating reamer holder with holder and reamer portions which transfer torque therebetween via a floating member. The floating reamer holder includes an elastic element which axially biases the holder and reamer portions. In an operative position, the floating reamer holder is configured to automatically enable angular misalignment, parallel misalignment and axial translation between the holder and reamer portion axes. In a non-operative position, the reamer portion axis is co-aligned with the holder portion axis. And the elastic element at least partially overlaps the reamer portion.

    摘要： The invention relates to a chuck (1) for a machine tool for machining a tubular workpiece (26) which rotates about a rotational axis 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 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, and bear chucking jaws (8a, b, c). Such a chuck is intended to be created with improved operating characteristics and extension to all chucking functions. To this end, for the external central chucking of a tube (26), there are provided centring slides (27a, b, c) which can be disengaged from the chuck head plate with a forward inclination towards the end of the tube to be machined and centre the tube by means of chucking claws (29) which are arranged at the front, free end of centring slide rods (28), said centring slides (27a, b, c) engaging via a toothed rod section (34) into a toothing (35) of a drive means assigned to each centring slide, and meshing for their part, on a toothing side (37) parallel to the side with the toothing, with a central toothed wheel (33) arranged concentrically with the rotational axis, wherein the central toothed wheel (33) synchronizes the movements of all the centring slides (27a, b, c).

    摘要： A rotary tool holder (20) includes a shank (58) having a flange (66), a tapered outer surface (64), and front and rear contact portions (60). The tapered outer surface (64) corresponds to the tapered bore of a spindle, and flexible circular cantilevers (70, 103) are provided at one or both contact portions such that a free end (76, 105) of the cantilevers expands radially due to centrifugal force to maintain contact with the tapered bore (53). The shank (58) can be formed from an inner member (113) and a sleeve (115) disposed thereover, in which portions of the sleeve (115) form the circular cantilevers. The circular cantilevers (256) can also be formed by a cavity (260) created in the shank (253). Alternatively, instead of circular cantilevers (256), the shank of the tool holder can have a taper which is optimized for a certain speed, wherein the taper of the shank (403) has a first taper at rest and a different taper (Φ2) at a desired speed.

    摘要： Disclosed is a chuck (11) that can be provided with three clamping jaws (13) which are guided in a non-torsional manner within inclined guiding members running at an angle from the longitudinal central axis. Said clamping jaws (13) are fixed to guiding means (19a) that are guided within the inclined guiding members (16, 17). The guiding means (19a) are configured as hollow cylinders and are provided with a connecting bar (22a), one end (23a) of which is connected to the hollow cylinder (19a) while the other end (24a) thereof is connected to a chuck piston (29), both ends (23a, 24a) being fixed in a rigid manner. The connecting bar (22a) is deformable or bendable in a radial direction such that said connecting bar (22a) can transmit power in a compensating manner from the chuck piston (29) to the guiding means (19a) and the clamping jaws (13) also during a relative movement thereof in a radial direction.

    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).
