ABSTRACT:
An indexing machine utilizes a rotating assembly for incrementally rotating a workpiece which is releasably held by a gripping mechanism adapted to rotate conjointly with the rotating assembly. The gripping mechanism is movable between a first position in which the gripping mechanism grips the workpiece and a second position in which the gripping mechanism releases the workpiece. The gripping mechanism is automatically and constantly urged towards its second position so as to facilitate the release of the workpiece from the gripping mechanism. Indexing plates, which determine the increments of rotation of the rotating assembly, are positioned at one end of the rotating assembly so that they may be quickly and easily removed. The rotating assembly includes a first member and a second member, which is mounted for reciprocating movement relative to the first member. A locking device releasably locks the second member to the first member so that the second member can rotate conjointly with the first member. When the second member is unlocked from the first member, the second member can be rotated relative to the first member.
