ABSTRACT:
A support for sensing the proper positioning of a workpiece and holding the workpiece for a machining operation in response to the proper positioning includes elements for sensing the position of the workpiece at a plurality of locations on the workpiece and a power drive mechanism for operating a clamp to secure the workpiece in the proper position. The sensing elements are connected in series to a power source and are actuated by engagement with predetermined locations on the workpiece when the workpiece is in the proper position. The clamp includes clamp arms which swing laterally away from seats for the workpiece as the clamp arms are moved forward to release one workpiece and accept another.
