Abstract: An indexing apparatus for selectively indexing a payload about an axis. The apparatus includes a housing that supports an indexable support table. A second retainer is provided on the indexable support table that is adapted to selectively axially engage a first retainer on the housing to lock the indexable support table in any one of a plurality of selected rotational positions about the axis. The apparatus also includes an axial displacement member that is movably supported within the housing to selectively engage the indexable support table while the indexable support table is locked in any one of the preselected rotational positions. Thereafter, the axial displacement member biases the indexable support table in a first axial direction out of the locked position and applies a rotational force to the indexable support table to rotate it a desired amount about the axis.

Abstract: 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.
