    摘要： A chuck assembly of the type adapted to be mounted on a spindle of a machine tool including adjusting means for accurately aligning the central axis around which the work engaging jaws are disposed with the longitudinal axis of rotation of the machine tool spindle on which the chuck assembly is mounted. The work engaging jaws are of a composite construction, each including a main section and an insert section which is replaceable and which includes a first work engaging abutment for substantially rigidly engaging a piece of work and a second abutment axially spaced from the first abutment for yieldably engaging a piece of work and serving as a steady rest.

    摘要： A chuck provided with two sets of opposed work holding jaws having axially oppositely angularly inclined rocker arm portions pivotable in swivel mountings to clamp and release the jaws, and means for pivotally actuating the arm portions of the jaws including a reciprocable actuator, two sets of longitudinally shiftable actuator bars-one for each set of jaws-carried by the actuator, and circumferentially adjustable wedge members also carried by the actuator at the ends of the bars, each actuator bar being associated with a respective work holding jaw and operatively connected to the rocker arm portion thereof so that movement of the actuator in one direction pivots the two sets of rocker arms in opposite directions to move the two sets of jaws in opposition to each other to engage the workpiece with a pinch action, the connecting means and particularly the actuator bars and the wedge members operating, shifting and adjusting automatically under clamping pressure to centralize the surface of the workpiece engaged by one set of jaws in the chuck, to compensate for eccentricity or out-of-roundness of the surface engaged by the other set of jaws, and to equalize or otherwise selectively distribute clamping pressure among the jaws.

    摘要： A sturdy, compact jaw assembly for work holding chucks and the like having a master jaw and a top jaw thereon, the latter being connected by suitable fastening screws to a T-nut mounted for sliding adjustment in a T-slot provided in the master jaw, and wherein work clamping and holding forces on the face of the top jaw are sustained jointly by a cross-key on and integral with the T-nut and an adjusting screw in the master jaw behind and bearing on the T-nut.
