    Abstract: A hydraulic chuck assembly for a tool machine includes first and second valve units disposed to control flow of pressurized fluids into a cylindrical chamber so as to move an annular piston to thereby move a taper socket along a spindle axis. Each valve unit includes a ball movable along a valve axis radial to the spindle axis such that the ball can be further forced to abut firmly against a valve seat during a high-speed rotation. Oil leakage can be prevented to ensure firm engagement of a workpiece with a collet head.

    Abstract: A collet chuck includes a tubular body and a rotating shaft assembly that is journalled within the tubular body and that defines a frustoconical recess therewithin. A belt pulley is sleeved fixedly on the rotating shaft assembly. A collet is disposed operably within the recess in the rotating shaft assembly, and is adapted to hold a rod-shaped workpiece therewithin. A movable member is mounted axially and movably within the tubular body for movement in tightening and loosening directions. A front oil chamber is formed in the tubular body, and is located immediately in front of the movable member. A rear oil chamber is formed in the tubular body, and is located immediately behind the movable member. A first oil passage is formed in the tubular body and is in fluid communication with the front oil chamber so that hydraulic oil can be fed thereinto, thereby moving the movable member within the tubular body in the tightening direction so as to compress the collet. A second oil passage is formed in the tubular body and is in fluid communication with the rear oil chamber so that hydraulic oil can be fed to thereinto, thereby moving the movable member within the tubular body in the loosening direction so as to release the collet.

    Abstract: A hydromechanical chuck intended to be mounted, with one end thereof, in a machine, such as a drilling machine, milling machine, lathe machine etc. and, with the opposite end thereof to releasably hold a shaft tool like a drill, a milling tool, a rotary saw blade, or a rotary grinding roll. The hydromechanical chuck is formed as a cone coupling chuck comprising a inner sleeve which can change is radial dimensions and has a central bore for receiving the shaft of a shaft tool. The inner sleeve is adapted for being radially compressed against the tool shaft. The hydromechanical chuck has a solid outer sleeve which is axially displaceable on the inner sleeve. The inner sleeve and outer sleeve are formed with a matching cone surface, which, upon a displacement of the outer sleeve on the inner sleeve, provides a radial compression of the inner sleeve. The chuck is formed with a hydraulic clamp pressure chamber comprising a hydraulic pressure medium which, upon pressurization, displaces the outer sleeve on the inner sleeve, thereby connecting the tool. A pressure release chamber releases the joint between the chuck and the tool.

    Abstract: A collet arrangement comprises a collet having a taper at its work-piece receiving segmented head. The collet is axially fixed relative to a chuck body by means of a screwed bush. The latter is locked axially to the chuck body by being trapped under the heads of bolts, and is locked against rotation by means of a pin. The chuck body is secured to the machine spindle. A tapered sleeve is slidable between the chuck body and the collet and is secured to a draw tube by bolts, an actuating plate and an adaptor ring. These bolts freely slide through the chuck body and can thus move the tapered sleeve in an axial direction relative to the collet so that their respective tapers cause the collet segments to grip and release the work piece. Unlike the normal draw back type of collet arrangement, the collet itself is therefore axially fixed.

    Abstract: In an automatic screw machine two spindles are mounted coaxially one within the other and are keyed together for rotation in unison in the indexing head of the machine. The inner spindle has a collet on one end thereof; the outer spindle is shiftable axially relative to the inner spindle between collet opening and closing positions. A spring, which surrounds the inner spindle at one end thereof, urges a washer on the inner spindle against one end of the outer spindle normally to urge the outer spindle resiliently into a collet closing position. A hydraulic cylinder, which surrounds the outer spindle at the side of washer remote from the spring, contains a piston which is engaged at one side with the washer and at its opposite side communicates with a fluid pressure chamber. To open the collet pressure is applied to the fluid in the chamber, thereby causing the piston to compress the spring and to permit the outer spindle to move to a collet opening position.

    Abstract: Advancing mechanism for a series of fixtures having collets for workpieces are actuated by a fluid actuated double-acting cylinder to lock and unlock the collet. A driven rotatable table has a plurality of equally spaced fixtures mounted thereon which are advanced seriatim to a plurality of machining stations where work is performed thereon. Each advancement moves a fixture to the unloading and loading station where the collet is released, the finished workpiece removed and a workpiece to be machined placed within the collet. The double-acting cylinder was actuated by the fluid to release the collet and after a workpiece was placed therein a reversal of the fluid clamped the collet in secured position. The collet is locked and unlocked by the operation of a transverse pin in a sloping slot in a sleeve which is advanced over the collet to move the sections of the head into clamped position to hold the workpiece. The table is driven to advance the collets the distance the fixtures are spaced apart and are accurately located by a shot pin which enters a hole in the table. Thereafter a dwell time is provided during which work is performed on the workpieces located at each of the stations. Any number of stations may be provided depending upon the number of machining operations to be performed.

    Abstract: A fluid operated chuck includes drive means having an annular groove formed therein. A fluid actuated collet engaging means engages an associated collet. A novel segmented collet includes a plurality of separate spaced portions having a tapered outer surface which cooperates with a tapered surface on the collet engaging means. Each of these collet portions has a radially outwardly extending flange at the inner end thereof which fits within the annular groove in the drive means for retaining the segmented collet in position. A generally cylindrical longitudinally split inner collet fits snugly within the segmented collet. A locating ring can also be disposed within the segmented collet, this locating ring having a central threaded hole formed therein. Pin means may also be provided between the collet portions for maintaining them in operative spaced relationship to one another. These pins can be carried by the drive means or the locating ring. A modified form of chuck includes a pair of pistons one of which is slidable upon the other, the pistons being movable in opposite directions to operate an associated collet. Fluid is introduced around the pistons to form a fluid bearing for the pistons and further to urge the pistons away from one another.
