摘要： Advancing mechanism for a series of fixtures having collets for workpieces are actuated by a fluid actuated double-acting cylinder to lock and unlock the collet. A driven rotatable table has a plurality of equally spaced fixtures mounted thereon which are advanced seriatim to a plurality of machining stations where work is performed thereon. Each advancement moves a fixture to the unloading and loading station where the collet is released, the finished workpiece removed and a workpiece to be machined placed within the collet. The double-acting cylinder was actuated by the fluid to release the collet and after a workpiece was placed therein a reversal of the fluid clamped the collet in secured position. The collet is locked and unlocked by the operation of a transverse pin in a sloping slot in a sleeve which is advanced over the collet to move the sections of the head into clamped position to hold the workpiece. The table is driven to advance the collets the distance the fixtures are spaced apart and are accurately located by a shot pin which enters a hole in the table. Thereafter a dwell time is provided during which work is performed on the workpieces located at each of the stations. Any number of stations may be provided depending upon the number of machining operations to be performed.

摘要： An apparatus for gripping the interior surface of an annular opening in a workpiece includes a baseplate and a set of elements circularly arranged and coaxial with a shaft or stud extending through and perpendicular to the baseplate. The elements are circumferentially spaced apart and are slidable radially of the shaft.Each element has a pair of aligned curved slots opening respectively to the opposite circumferential ends thereof. Biasing springs are secured to the baseplate and positioned thereon to extend from a slot in one element to the adjacent slot in the adjacent element. These biasing springs bear against the side surfaces of adjacent slots for biasing the elements radially inwardly to a contracted position. An actuating member which is in the shape of a camming disc, is movable relative to the baseplate and cooperates with the elements to move them radially outwardly so that they engage and grip the interior surface of the opening in the workpiece.

摘要： A core 4 is mounted on a machine tool for indexable rotation about an axis 2A, so as to bring respective cassettes 10 into position where they can be operated on by tools held in the machine tool spindle 6. The cassettes 10 may hold workpieces 14,14A for machining. After machining, the workpiece 14A is measured by a probe 20 held in the machine tool spindle 6. A pre-calibrated artifact 26 held on another cassette 10 is then indexed into the same position as previously occupied by the workpiece 14A, and comparative measurements are made of the artifact. The accuracy of these comparative measurements is increased because the artifact 26 resides on the machine tool in the same thermal environment as the workpiece during the machining, and because the measurements are made in the same position within the working volume of the machine tool, so that the same regions of the machine tool's measurement scales are utilized.

摘要： A rotary turret numerically controlled punch press is provided with a discharge station at 90.degree. from a punching station. A part is clamped in the turret, separated from a larger workpiece and then rotated with the turret to the discharge station. A transfer arm is slaved to the NC punch press and engages the part at an exact attitude and position relative to a reference point on the part and transfers the part to a rotary chuck. The part is placed in the chuck at an exact attitude and with the reference point at the axis of rotation of the chuck.Four rotary chucks are provided on a rotary turret contouring apparatus. The turret is rotated 90.degree. to position the part at a cutting station.A band saw is provided with rotary guides for changing the angle of the saw. While the part is rotated and linearly translated toward and away from the saw by the contouring apparatus, the saw cuts a peripheral shape on the part with the blade changing its angular attitude where necessary. An air cushion support holds the edge of the part at the saw blade.After cutting, the contouring turret is rotated another 90.degree. bringing the part to a deburring station. The motion of the part at the deburring and cutting stations is identical for simultaneous cutting and deburring. Next the turret is rotated another 90.degree. and the deburred part is engaged by a second transfer arm to remove the part and locate it for subsequent treatment.

摘要： A bar holder arrangement for holding bar stock material to be fed to an automatic machine tool comprises a frame and an elongated bar holder mounted in the frame. The bar holder includes an elongated member and a plurality of lever members which are mounted on the elongated member for pivotal movement between a gripping position and an open position, each lever member has at least one upstanding gripping member disposed on at least one end thereof. The lever members are pivotally disposed at different locations with respect to each other along the elongated member so that an upstanding gripping member of one lever member cooperates with an upstanding gripping member located at the end of the next adjacent lever member. Means are provided for pivoting the lever members between the gripping position and the open position. When the lever members are in the open position, a length of bar stock material may be dropped into the bar holder. The lever members are then pivoted to the gripping position so that the upstanding gripping members define a receiving means which holds the length of bar stock material in place. The arrangement may include a plurality of bar holders mounted in a reel formed by multi-armed spiders and a plurality of elongated members. The reel is rotatably mounted in the frame structure.

摘要： A manipulator (26) for controlling force and position of a retained device (22) is disclosed. Various construction details are disclosed that provide a manipulator (26) which is back driveable and which provides planar control of both force and position of the device relative to an object being worked on. In a particular embodiment, the manipulator (26) includes an actuator assembly (46) having two pairs of voice coils (58, 59), a housing (56) gimbaled to a frame (45) and engaged with the actuator assembly (46) through a universal joint (54), and a tool (22) retained in a distal end of the housing (56). Excitation of the voice coils (58, 59) produces a planar force on the joint (54). Movement of the joint (54) results in pivoting of the housing (56) about the gimbal (76) and spherical motion of the device. In a further embodiment, the manipulator (26) includes a body (57) gimbaled to the housing (56) and a plurality of force transducers (82) disposed about the body (57) and between the body (57) and housing (56). Forces on the device may be measured by the response of the transducers (82). In another embodiment, the manipulator (26) includes a plurality of position sensors (114, 116) disposed about the gimbal (76) and between the housing (56) and frame (45). The plurality of position sensors (114, 116) respond to pivoting motion of the housing (56) such that the position of the device (22) may be monitored.

摘要： An index table comprising a base, a main plate mounted on the base, a drive wheel mounted for rotation on one side of the main plate about a first axis transverse to the main plate, a work plate on the other side of the main plate rotatably mounted about a second transverse axis spaced from the first transverse axis, and a segment wheel mounted on the one side of said main plate and fixed with relation to the work plate. Circumferentially spaced segment drivers are mounted on the drive wheel and are adapted to engage circumferentially spaced slots on the segment wheel to intermittently drive the segment wheel and in turn the work plate. A yoke plate is mounted on the one side of the main plate for movement radially with respect to the drive wheel and the segment wheel. As the drive wheel rotates, each segment driver engages the yoke plate and moves the yoke plate relative to the segment wheel. As the yoke plate is moved radially outwardly and inwardly, it swings arms pivoted to the main plate, moving pins on the arms into and out of engagement with the sides of a pair of adjacent spaced slots on the segment wheel to unlock and lock the work plate in position. Movement of the yoke plate also functions to operate oil pistons that supply lubrication to the index table.
