A lathe chuck for aluminum alloy hubs, which includes a pull rod shaft, a positioning unit fixing seat, a protective cover and a hollow shaft sleeve, wherein the upper cover and the chuck body are connected together by screws, forming a chuck main body; a mounting hole is formed in the bottom of the chuck body, so that the chuck is mounted on a machine tool; the positioning pins are mounted between the upper cover and the chuck body by screws; the pull rod shaft, a annular pressing plate and a tensioning plate are connected together by screws; the tensioning plate and the positioning pins form sliding fit by copper sleeves, and the positioning unit fixing seat, the protective cover and the hollow shaft sleeve are arranged together by screws to form a combination; the spring, the sliding blocks and the cuneiform taper sleeve are mounted in the combination.

A tool holding system for a rotary power tool is configured to clamp around a working tool when the working tool is inserted in the tool holding system. The tool holding system includes a sleeve having a frustroconical inner surface portion, a collet having frustoconical outer surface portion complementary to the inner surface portion, a spring mount operably connected to a motor for rotation by the motor, and a spring. The spring includes a first end portion operably connected to the collet to bias the collet toward a first position whereat the outer surface portion engages the inner surface portion, and a second end portion rotationally fixed with respect to the spring mount.

A tool holder, particularly a hand-held power tool holder, is provided for an oscillating and/or rotational drive of at least one insertion tool. The tool holder includes at least one holder-side fastening element that is provided at least substantially for a coupling with the at least one insertion tool. The tool holder also includes at least one bearing unit provided for movably mounting the at least one holder-side fastening element in a movement at least partially deviating from an axial direction. The movement at least partially deviating from the axial direction of the at least one fastening element is provided at least substantially for creating a fastening force in the axial direction.

A device for processing wafer-shaped articles comprises a rotary chuck having a series of pins adapted to hold a wafer shaped article on the rotary chuck. Each of the pins comprises a cylindrical body and a projecting gripping portion formed integrally therewith. The cylindrical body and gripping portion are made from a ceramic material. The gripping portion comprises cylindrical surfaces having a common generatrix with surfaces of the cylindrical body.

A device for supporting and gripping containers (1,1a), comprising a base (10;110;210) which defines an upper surface (15;115,215) supporting a container (1;1a); devices (20;120;220) for gripping the container (1,1a), associated with the said base (10;110;210); and devices (30;130;230) for actuating the devices (30;130;230) for gripping the container (1,1a).

A chuck device for holding a plate material workpiece supplied to a machine tool without deforming the workpiece is provided. A housing has a workpiece contact surface arranged to face workpiece holding claws, and when holding of a workpiece is released, a plurality of rods integrally swings so that the workpiece holding claws are moved away from the workpiece contact surface of the housing and moved away from each other, and when holding the workpiece, after the plurality of rods integrally swing so that the workpiece holding claws are brought close to the workpiece contact surface of the housing and brought close to each other, the plurality of rods moves integrally in parallel with the forward/backward moving direction of a drive body to bring the workpiece holding claws into contact with the workpiece.
