摘要： A workholding apparatus includes a body, and a workholding sleeve composed of metal and carried by the body. A fluid chamber receives a fluid between the body and the workholding sleeve. Under fluid pressure, the sleeve is radially displaceable and recoverable to a high degree. For example, when displaced under fluid pressure, the sleeve experiences substantially complete and repeatable strain recovery of at least about 2% of its overall cross-sectional area. Preferably, the sleeve is composed of Nitinol.

摘要： A work holder assembly for use in clamping a workpiece being machined. A chuck includes a fixed sleeve about which is mounted a rotatable collet. A plurality of individual clamps extend from circumferential spaced locations associated with the collet. The clamps each include a first spring biased and linear traveling component actuating a second radially traveling and adjustable component into engagement with annular disposed locations of the workpiece. Each the clamps exhibits a wedge shape at an interface between the linear and radial components, both in order to minimize clamping forces and to prevent backdriving of the clamps by the tooling. A fluid pressure extends through a location in the chuck, the collet further having a fluid delivery component in communication with the fluid supply and which is in contact with workpiece engaging locations, to overcome the spring bias of said pin in a fluid actuated release condition.

摘要： A group of fixtures for thin-walled shell/cylindrical components (10) while they are being machined internally and externally, has a mounting base (1) having mounting holes, positioning pins and clamps to locate one end of the thin-walled component. A supporting arbour or cylinder (5) is fixed in the base. A circular lid (12) is fixed to the supporting arbour or cylinder and has a wedged step to locate the other end of the cylindrical component for internal and external machining, or the major open end of shell component for internal machining. A pair of modified vehicle wheel inner tubes (8) are disposed around the supporting arbour or cylinder. A multi-layered sacrificial liner (7) surrounds the pressure element and is adapted to fit between it and the thin-walled components. When properly inflated according to the design and validation procedure, the fixture adaptively holds the thin-walled components for machining, with sufficient supporting rigidity and dynamic stability, so as to maintain the machining precision and surface finish to an acceptable engineering standard. Furthermore, a reasonable and practical design and validation procedure is supplied, easily adapted to different sized thin-walled shell/cylindrical components.

摘要： A method of dialing a workpiece having an axis into a chuck includes providing a chuck assembly having a plurality of independent hydraulically controlled jaws distributed about a central axis, each jaw having first and second hydraulic chambers. The method further includes the steps of inserting a portion of the workpiece into the chuck assembly, pumping hydraulic fluid uniformly into each of the first chambers until the jaws are substantially touching the perimeter of the workpiece, and adjusting one or more of the jaws to align the axis of the workpiece with the central axis of the chuck assembly by pumping hydraulic fluid into at least one of the chambers of at least one of the jaws. The method also includes the step of pumping hydraulic fluid uniformly into each of the first chambers until the jaws are clamped around the perimeter of the workpiece at a predetermined pressure.

摘要： A power chuck assembly has a lathe spindle extending along and rotatable about an axis and having axially opposite front and rear ends. An axially displaceable actuator rod extends at the axis through the spindle and has front and rear rod ends at the respective spindle ends. This rod is rotatable about the axis between two angularly offset end positions. A coupling head secured to the front spindle end has a plurality of bolts displaceable radially between inner and outer positions. A chuck provided with an axially rearwardly projecting annular flange engageable over the head is formed with at least one radially but not axially open recess in which the bolts are engageable in the outer positions thereof. Actuators are connected to the bolts for displacing them from the inner to the outer positions so that, when the chuck is fitted over the coupling head, the bolts engage in the recess and axially lock the chuck on the coupling head. An actuating element is axially displaceable in the chuck for gripping and releasing a workpiece, normally by radially displacing jaws on the chunk. Interengageable coupling formations on the front rod end and on the actuating element are axially engageable with each other for axially coupling the rod to the element in one angular end position of the spindle and axially unengageable with each other in the other angular end position for axially decoupling the rod and element. A linear actuator is connected between the rear spindle and rod ends for relatively axially displacing the spindle and rod and thereby axially displacing the actuating element of a chuck engaged on the head.

摘要： A chucking device in which a chuck body has aligned opposed jaws reciprocable toward and away from each other on a common axis and rotatable on the axis. Respective actuators are provided for the jaws to effect the reciprocation of the jaws on the axis. One jaw locks to the chuck body in an outermost position while the actuator therefor develops a greater thrust than the actuator for the other jaw.

摘要： A rock drilling apparatus for rotary drilling has a chuck which is axially movable by means of a double-acting, pressure fluid actuated feed motor. It has also a stationary chuck. The movable chuck grips a drill string when supplied with pressure fluid; the stationary chuck grips the drill string when relieved of pressure fluid. During inserting or withdrawing of the drill string, the supply conduits of the chucks are connected to either of the supply conduits of the feed motor so that, automatically, the chucks operates concordantly with the feed motor.
