摘要： A chuck is described. The chuck may include: a plurality of chuck jaws. Each chuck jaw is radially movable toward and way from a chuck axis, and each chuck jaw including: two substantially coplanar surfaces perpendicular to a chuck jaw axis and substantially parallel to the chuck axis; a ridge located between the two substantially coplanar surfaces; and two troughs, one trough located between the ridge and one of the substantially coplanar surface and the other trough located between the ridge and the other coplanar surface. A chuck jaw and method of configuring a chuck are also described.

摘要： The invention has been developed to solve the drawbacks of the conventional chuck construction, and it is an object of the invention to provide a compact chuck construction, by omitting the axial movement parts, which are inevitable in the conventional chuck construction. A chuck body 10 comprising an axially movable plunger 30 and a jaw 20, in which said jaw 20 having master jaw body 24 obliquely arranged with respect to the axis, said plunger 30 having a bush 41 which act as a wedge, and a driving means 50 at the rear end of the master jaw body 24, said wedge means 40 having a structure of canceling a moment applied to the jaw 20 as a result of clamping and the driving means 50 providing a reactant force to the master jaw body 24 for canceling drawing force applied to the plunger 30.

摘要： A chuck having the function of pulling in work is constructed so that the function possessed by an axially movable chuck body portion is superceded by an immovable body portion, a plunger and an urging means, thereby dispensing with the movable chuck body portion. That is, it is a chuck of a construction in which, of the functions of the conventional movable body portion, the guide function of controlling the movement of the jaw axially and circumferentially of the chuck shaft is superseded by a fixed body portion (10) and an urging means (50) for pressing the jaw (20) forwardly of the chuck, while the radial movement of the jaw for gripping the work is effected by a wedge means (40), and the rotational moment of the jaw produced as a reaction to the work holding force is supported by the wedge means (40) cooperating with part of a plunger (30) or the plunger and the cylinder section (16) of the front of the chuck body main body.

摘要： A chuck (30) having a body (54) formed with a bore (60) having a fixed clamp segment (134) and a movable clamp segment (166) located in radial opposition. A pair of ribs (142) on fixed segment (134) and a single rib (172) on movable segment (166) extend radially inward and cooperate to clamp a shank (42). A sleeve (78) is positioned about body (54) and is movable axially relative thereto. A camming section (88) formed on an interior wall of sleeve (78) is captured between a head (124) of a pin (122) and a detent ring (132) to latch sleeve (78) in an unclamped mode. When shank (42) is inserted into bore (60), the forward end of the shank (42) engages pin (122) to move head (124) against camming section (88) which, in turn, moves section (88) past the detent ring (132). Thus, the sleeve (78) is unlatched and moved forward to compress a plurality of rollers (196) against fixed segment (134) and movable segment (166) to place sleeve (78) in a clamped mode, clamping shank (42).

摘要： A chuck (30) with a generally cylindrical body (34) has a gripping mechanism (36) that is actuatable to a closed position in which the gripping mechanism (36) retains a tool with respect to the body (34). An annular nut (66) has a threaded portion (68) in threaded engagement with the gripping mechanism (36) so that rotation of the nut (66) in a closing direction actuates the gripping mechanism (36) to a closed position and rotation of the nut (66) in an opening direction, opposite the closing direction, actuates the gripping mechanism (36) to an open position. One of the nut (66) and the gripping mechanism (36) includes a rotational stop (78) which, when the gripping mechanism (36) reaches a predetermined position while being actuated by rotation of the nut (66) in the opening direction, abuts the other of the nut (66) and the gripping mechanism (36) in a rotational direction with respect to the axis (52) of the body (34) to oppose further rotation of the nut (66).

摘要： Each of master jaws (17) has a middle spherical part guided for sliding movement by a spherical guide surface (16) formed in a chuck body (2), a round back end part (19) extended slidably through a spherical bearing member (12) supported on a support member (10) attached to a middle part of a driving member (5). Each master jaw (17) is provided with a through hole (26) extending between the front and the back end thereof and a sliding member (30) is inserted in the through hole of the master jaw (17) through the front end of the same so as to come into sliding contact with a stopper (36) attached to a chuck body (2). Therefore, the state of sliding contact between the sliding member (30) and the stopper (36) can be adjusted on the side of the front part of the chuck and work for adjusting the state of sliding contact can be easily achieved.
