Abstract: Pressing device for the relative axial displacement of two mutually coaxial parts that can only be displaced towards one another by using a high pressing power, for example collet chucks or clamping sleeves, into corresponding holes in tool or collet chuck holders. The device has a housing (7) consisting of two at least partially separable shells, which can be placed coaxially around the parts to be pressed. In the closed state, the housing has coaxial annular contacting edges (19, 20) for engaging with one of the parts to be pressed. In the inner chamber (21) of the housing there is an axially displaceable pressing plate (22) with an annular contacting edge (23) for engaging with the second part to be pressed. The press plate is displaced by a number of pressure cylinders (13, 14) arranged in a ring at equal angular distances between the housing and the press plate.

Abstract: A true length collet chuck assembly is adapted to receive and actuate a quick change, segmented collet having a flange extending radially outwardly from the outer surface of the collet adjacent a rear face of the collet. The collet chuck assembly comprises a chuck body having a longitudinally extending bore defined by an inwardly facing, cylindrical surface on the chuck body. The inwardly facing, cylindrical surface on the chuck body defines a circumferential groove for receiving the radially outwardly extending flange on the collet to thereby restrain the collet against axial movement relative to the chuck body. A collet closing sleeve, disposed within the chuck body and axially displaceable relative thereto, has an outwardly flaring interior surface adapted to engage an outwardly flaring surface on the collet. Axial displacement of the closing sleeve relative to the chuck body in one direction compresses the quick change collet to grip a workpiece and axial displacement of the closing sleeve in the other direction allows the quick change collet to expand and release the workpiece. A collet actuator is disposed within the chuck body and is adapted to be coupled to an actuator driver for axially displacing the collet actuator relative to the chuck body. The collet actuator is releasably coupled to the rear portion of the closing sleeve. Axial displacement of the collet actuator by means of the actuator driver correspondingly displaces the closing sleeve whereby the collet is compressed or allowed to expand.

Abstract: A holding chuck has a clamping device for firmly holding the tire-wheel in the position aligned with a center axis of a holding chuck. Chatter-suppressing dampers are disposed on an intermediate plate fitted around the chuck. The dampers are disposed on circles concentric with the center axis of the holding chuck. Each of the dampers has a damping rod extending in the direction parallel to the center axis and abutting a rim of the wheel. A damper cover is disposed between the rim of the wheel and the dampers and fastened to the holding chuck. The damper cover has slot holes disposed on a circle concentric with the center axis of the chuck which allow the damping rods of the dampers disposed on only one of the concentric circles to extend therethrough and abut the rim of the wheel.

Abstract: A tool holder includes a body, a collet, and a collet mover. The body is formed to include a collet chamber and a collet-mover chamber arranged to communicate wit the collet chamber. The collet includes a tool-gripping surface arranged to define a tool-receiving chamber adapted to receive a machine tool therein. The collet is mounted for movement in the collet chamber along a central axis of the body between a tool-grip position to cause the tool-gripping surface to move radially inwardly toward the central axis to grip the machine tool in the tool-receiving chamber and a tool-release position to cause the tool-gripping surface to move radially outwardly away from the central axis to release the machine tool. The collet mover is positioned to lie in the collet-mover chamber and is coupled to the collet to draw the collet along the central axis to the tool-grip position.

Abstract: A collet nut has a nut member for threaded engagement with threads on a collet holder. A sleeve member is rotationally coupled to the nut member in a first tightening mode of the collet nut. An annular ring is rotationally coupled to the sleeve member and rotationally coupled to the nut member in the first tightening mode. Facing ramped bearing surfaces are defined between opposing faces of the annular ring and the nut member and bearing devices, such as balls, are disposed between the opposite faces. In the first tightening mode, the nut member and the annular ring rotate as a unit. In a second tightening mode, the annular ring rotates relative to the nut member so that opposing high sections of the ramped bearing surfaces are brought rotationally closer thereby forcing the annular ring axially away from the nut member which imparts an additional axial force to a collet engaging member of the collet nut.
