Abstract A workpiece orienting device comprising means for supporting a randomly oriented workpiece, having an eccentric portion to be ground to size for selective engagement with a pair of work centers, a pair of work centers, means for forcefully engaging a supported workpiece with the work centers, motor means for rotatably driving at least one of the work centers, an orienting finger selectively located to be radially aligned with the eccentric portion of a supported workpiece and displaceable from a retracted remote position to an advanced position, the advanced position being selectively located so that the eccentric portion of the rotating workpiece will strike the orienting finger at a predetermined peripheral location, means for advancing the orienting finger from the retracted position to the advanced position, means for sensing when the orienting finger can be advanced from the retracted position to the advanced position without abutting against the eccentric portion and for actuating the advancing means, and means for maintaining the orienting finger at the advanced position whereby rotation of the rotating workpiece will be halted when the eccentric portion strikes the orienting finger thereby establishing a predetermined workpiece orientation.
A workpiece orienting device comprising means for supporting a randomly oriented workpiece, having an eccentric portion to be ground to size, for selective engagement with a pair of work centers, a pair of work centers, means for forcefully engaging a supported workpiece with said work centers, motor means for rotatably driving at least one of said work centers, orienting means selectively located to be radially aligned with the eccentric portion of a supported workpiece and displaceable from a retracted remote position to an advanced position, said advanced position being selectively located so that the eccentric portion of the rotating workpiece will strike said orienting means at a predetermined location, means for advancing said orienting means from said retracted position to said advanced position, means for sensing when said orienting means can be advanced from said retracted position to said advanced position without abutting against the eccentric portion, and for actuating said advancing means, means for maintaining said orienting means at said advanced position whereby rotation of the rotating workpiece will be halted when the eccentric portion engages said orienting means thereby establishing a predetermined workpiece orientation.
