摘要： The invention relates to a workholder (10) for holding a workpiece to be processed in a machine tool, which workholder (10) is in the form of a annular body (12) having a central through hole (14), said annular body (12) having at least one weakened area (18, 20; 34, 36, 38, 40; 50, 52, 54, 56) obtained by material removal, as well as at least one pressure chamber (22; 42, 44; 58, 60) assigned to said at least one weakened area (18, 20; 34, 36, 38, 40; 50, 52, 54, 56) that can be charged with a pressurized fluid. Said at least one weakened area (18, 20; 34, 36, 38, 40; 50, 52, 54, 56) is dimensioned and arranged so as to cause said annular body (12) to be elastically deformable in an axial and/or a radial direction (a, r). As a result, with pressure acting on said pressure chamber (22; 42, 44; 58, 60), said annular body (12) can then be deformed elastically in a well-defined manner in an axial and/or a radial direction (a, r).

摘要： A method of alignably supporting an eccentric work piece for rotary movements uses a work piece holder that supports the work piece in alignment during rotary operations. A plurality of cooperating aligning members mounted along the rotary axis of a rotary unit, provides pivoting movements relative to the rotary axis while bearing the work piece. These pivoting movements of the aligning members enable the work piece to be aligned during rotary operations.

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.

摘要： A lever-operated jaw chuck adaptable for compensating and centering actions through minor modification, and hence useful for bar work, chucking work and shaft work. A central axial passageway extends through the chuck for receiving either a worklocating center or a guide for a jaw-lever actuator. The jawlever actuator is an annular cam within the chuck that surrounds, is carried by, and moves axially with a reciprocable tubular operator. A circumferential gap between the operator and actuator permits transverse floating movement of the actuator and hence, a compensating chuck action. The gap is unobstructed in a forward direction, toward the face of the chuck, to receive the removable guide. Placement of the guide within the gap between the operator and actuator prevents transverse floating movement of the actuator without regard to the angular position or circumferential location of the guide within the gap. The actuator guide is constructed to permit a workpiece to pass through the central passageway of the chuck.

摘要： A chuck having a set of centering jaws and a set of compensating jaws, two axially movable plungers operatively connected with the jaws of the respective sets, with the plunger for the compensating jaws including a ball member with a universally movable socket member thereon for compensating action of the associated jaws, and fluid-operated mechanism operative to move the plungers for closure of the centering jaws on work before the compensating jaws close thereon, and for applying full workgripping force to the jaws only when all jaws are in engagement with work. The compensating jaws are convertible into centering jaws by releasably locking the socket member to the ball member against movement from a neutral position in which the converted jaws are held centered on the chuck axis.
