摘要： A fluid-actuated workholding apparatus that includes a base member that has a longitudinally extending slot and a fixed jaw attached thereto. The apparatus further includes first and second movable jaw members that are operably supported on the base member for movement towards and away from the fixed jaw member along the longitudinally extending slot. A clamping assembly is operably supported within the longitudinally extending slot and serves to define a fluid receiving cavity for receiving a pressurized fluid therein. The clamping assembly communicates with the first and second movable jaw members such that when a predetermined amount of pressurized fluid is admitted to the receiving cavity, the first and second movable jaw members are caused to move away from the fixed jaw member. The clamping assembly also includes means for biasing the first and second movable jaw members towards the fixed jaw member when the pressurized fluid is removed from the receiving cavity to enable a first workpiece to be clamped between the first movable jaw member and the fixed jaw member under a compressive force and a second workpiece to be clamped between the second movable jaw member and the fixed jaw member under the same compressive force.

The workpiece chucking device comprises a diaphragm 14 having chucking claws 35 in the front of a base 12 which will rotate along with a spindle 11 of a machine tool, a piston which will be moved back and forth by switching fluid fed into a hollow chamber 15 of the base, a cylindrical member 21 inserted in a center of the piston and held to the base, first balls 24 fitted into even-numbered ones of a plurality of transmitting holes formed in the cylindrical member, as well as second balls fitted into odd-numbered ones of the transmitting holes, and a recessed fitting portion 29 provided in an outer circumferential surface of a slider 26 which is inserted into the cylindrical member and connected to the diaphragm so that parts of circumferential surfaces of the first and second balls will be fitted into the recessed fitting portion 29. The slider will retreat only when the first balls are pushed into the recessed fitting portion by a first tapered portion of the piston, while the slider will be advanced when only the second balls are pushed into the recessed fitting portion by a second tapered portion of the piston.

摘要： A work spindle for a machine tool. The work spindle has a spindle guard tube, a clamping arrangement, a clamping force generator, which is arranged on the spindle guard tube and operates the clamping arrangement, and which has at least one first cylinder chamber enclosed by a first cylinder housing and a first piston, in such a way that a large band width of different clamping forces may be generated simply. The clamping force generator has a second cylinder chamber enclosed by a second cylinder housing and a second piston. Additionally, for operation of the clamping arrangement, both cylinder chambers are always subjected to a pressurized medium. Furthermore, to generate different clamping forces, the clamping force generator is switchable over from a first working mode, in which at least the first piston operates the clamping arrangement, into a second working mode, in which at least the second piston operates the clamping arrangement.

摘要： A chuck drive system, especially for a rotating clamping device of a machine tool, includes a rotating chuck cylinder, a stationary frame positioned adjacent the chuck cylinder, and a piston which subdivides the cylinder into two pressure chambers and is formed with a piston rod having one end rotatably supported in the stationary frame. Fluid under pressure is supplied to the pressure chambers, whereby check valves are positioned in the passageways to the pressure chambers to maintain the fluid pressure in the pressure chambers. In order to monitor the fluid pressure in the pressure chambers, a pressure monitoring unit is provided which includes pressure sensors that are respectively assigned to the pressure chambers for determining the fluid pressure in the pressure chambers separately and independently from one another. The pressure sensors form electrical output signals commensurate with the fluid pressure in the pressure chambers, with the monitoring unit deriving from the output signals an analog differential pressure signal to determine the actual actuation force applied upon the piston.

摘要： A vacuum pod system for supporting a workpiece. A work table is provided with a shouldered opening formed therein in communication with a vacuum source. A pod is provided having a first longitudinal portion of a first outside diameter which seats on the shoulder in the opening, and a second longitudinal portion for supporting the workpiece, the second portion having a second outside diameter unequal to the first diameter. A passageway extends through the pod for providing communication between the first and second portions so that when the workpiece is supported on the second portion, a vacuum generated by the vacuum source creates a suction force which secures the workpiece to the pod.

摘要： An actuator has a cylinder centered on an axis and a piston axially displaceable in the cylinder, defining therein axially opposite front and rear compartments, and having an axially rearwardly projecting stem. A distributor is axially fixed but rotatable about the axis on the stem offset from the cylinder. The piston and distributor are formed with passages for pressurizing and depressurizing the compartments. At least one control element is fixed on the distributor offset from the cylinder. A sleeve coaxially surrounds the piston stem and forms a rear abutment against which the piston engages in a rearmost position of the piston. Formations on the cylinder and on the sleeve can axially displace the sleeve on the cylinder and fix the sleeve on the cylinder in any of a multiplicity of axially offset positions thereon. Respective front and rear control members extending axially rearward from front and rear bearings on the cylinder and sleeve are engageable with the control element to operate same.

摘要： Workpiece chucking apparatus includes a chuck body mounting a first plurality of prepositioning lock-up fingers and a second plurality of gripping fingers. The lock-up fingers are biased together radially outwardly or inwardly into engagement with a peripheral wall of a workpiece to initially locate and support the wall of the workpiece in a centered position with respect to a central axis of the chucking apparatus. An inflatable bladder flexes the remaining gripping fingers into gripping engagement with the peripheral wall to further radially support the wall in preparation for machining, without disturbing the prepositioning of the workpiece.
