ABSTRACT:
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.
