摘要： An indexable workholding apparatus. The apparatus has a column member with at least one pair of workholding jaws operably attached thereto. The column member is rotatably and axially supported on a shaft member that is operably attached to an indexing assembly. The indexing assembly is constructed to axially displace the column along a longitudinal axis to a disengaged position upon the initial application of a rotary force to the shaft member. When in the disengaged position, the column can be selectively rotated about the axis by the further application of rotary force to the shaft member so that the column may be positioned in a predetermined angular position. A damping apparatus is attached to the shaft member and column for damping the return axial and rotary motion of the column and shaft member when the application of rotary force is discontinued. The indexing apparatus further includes a device for locking the article in a plurality of predetermined angular positions when the application of rotational force to the indexing assembly is discontinued.

摘要： A rotary indexing mechanism for indexing a shaft or shaft mounted member in precise rotary increments and with precise end-of-movement positioning includes a reciprocable rack and pinion mechanism coupled to a rotatably mounted shaft. The pinion is coupled to the shaft through a one-way clutch so that movement of the rack in a first direction is coupled through the clutch to cause a corresponding rotation of the shaft with the clutch uncoupling the shaft during movement of the rack in the opposite direction. A first stop member(s) is carried by the shaft for movement along a path that orbits the shaft axis. A second stop member is carried by the rack along a linear path that intersects the orbit of the first stop member. As the rack rotates the shaft through a rotary increment, the rack-carried second member is positioned in the orbit of the first stop member with the two members engaging to halt further rotary movement. The rotary indexing mechanism allows successive rotary increments with precise end-of-movement positioning determined by the two interengaging members. In the preferred embodiment, one or both of the members is adjustable to provide various end-of-movement positions.

摘要： A workpiece indexing assembly which causes incremental rotation of a turntable from one work station position to another being actuated by a linearly translating driver. The mechanism includes an indexing hub having a number of radially spaced notches, a one-way clutch dog, a locking pawl and a driving dog. Upon retraction of the driver the driving dog becomes disengaged from one notch and is rotated until engagement occurs with another notch. Retraction also causes disengagement of the locking pawl. Rotation of the table is prevented during retraction by the one-way clutch. Upon extension of the actuator, the one-way clutch allows rotation. When the next work station position is reached, the locking pawl and the one-way clutch are reseated into hub notches. The driver is connected to the driving dog by a link featuring overcenter travel to insure firm locking of the turntable at a work station position.

摘要： In processing apparatus, especially fruit processing machinery, incorporating two functional subassemblies with movements which are synchronous with respect to one another, there is provided a fail safe indexing mechanism which prevents operation of one or the other of such subassemblies should for any reasons apparatus operational sequencing or synchronization be interrupted. The fail safe means utilizes a ratchet having a locking means to prevent over-travel thereof. In addition, a signalling means is associated with the locking means which allows operation of one subassembly only during a limited period of each machine cycle, provided all assemblies and sub-assemblies are in their normal location for that period of the timing cycle.

摘要： A rotatable turret for bringing any selected one of a plurality of tool holders into operative position relative to a workpiece, is characterized in that the turret can be rotated in either direction so that it need follow only the shortest path between the location of the old tool holder and the location of the new tool holder when changing from tool to tool. For this purpose, the turret has a rotatable hub with a plurality of blocks on its periphery slidable relative thereto in directions parallel to the axis of rotation, into and out of slots on a fixed member, the location of the slots corresponding to the operative locations of the tool holders. The blocks are all secured to the keeper ring of an annular electromagnet, whose strength is sufficient to retain the keeper ring attracted when the blocks are out of the slots, but whose strength is insufficient to retain the keeper ring when the blocks are in the slots. Springs act between the hub and the blocks to urge the blocks into the slots; and cam surfaces on the fixed member cam the blocks out of the slots against the action of the springs in one direction of rotation of the hub. A driving ring for the hub has abutment surfaces that contact the hub only in that one direction of rotation; whereas the same driving ring has abutment surfaces that contact only the blocks in the other direction of rotation, and then only when the blocks are withdrawn from the slots.

摘要： In an apparatus for manipulating workpieces in an electron beam drilling machine, workpieces are mounted on rotatable disks which in turn are mounted on a housing which is rotatable and translatable. Each disk, as a fixture holding the workpiece, is unlocked, rotated, and locked in a new position by the motion of a single driving member and associated elements. The single driving members associated with each workpiece indexing assembly are driven through a system of gears from a single central shaft which passes through the vacuum chamber wall to externally mounted actuators and controls.

摘要： A rotary index table wherein a detent oscillating about the table axis of rotation is translated radially inwardly during indexing and retracted radially outwardly during the return stroke of the detent, both actions being accomplished through a positive acting toggle link arrangement. The positive detent engagement with the table during indexing prevents table overtravel, and a locking detent is utilized to produce final table orientation. The table also includes expansible chamber motor means axially translating the table into a frictional locking engagement with its base.
