Abstract
A work piece holding mechanism which provides multi position part holding capability to automatically sequentially hold and present a work pieces in multiple orientations for work thereon. The work piece holding mechanism includes two rotatable clamp means for clamping the work piece therebetween. Rotation of at least one of the rotary clamps is driven by a rotary drive mechanism, preferably a rotary air cylinder. The rotary air cylinder is provided with at least one fixed rotational stop. In addition, the rotary air cylinder may be provided with one or more actuatable intermediate stops. Rotation of the work piece can be accomplished by driving the rotary air cylinder to a predetermined position against either a fixed stop or an actuatable stop. Each of such stop positions results in a different orientation of the work piece and thus a different work plane on which the robot can operate. Loading of the work piece into the holding mechanism can be performed automatically by the robot with the robot controller also commanding the opposing clamps of the work holder to engage the work piece. Similarly, removal of the work piece from the holding mechanism can be automatically performed…
