ABSTRACT:
A pair of opposed plungers slideably arranged in a bore on a work-holding fixture have their confronting end faces inclined to the axis thereof in spaced apart relation. A key is disposed between the confronting ends of the plungers. The fixture is designed so that when a workpiece is placed thereon it depresses one of the plungers. Thereafter the other plunger is moved toward the key to shift the key laterally into engagement with the inclined end face of the depressed plunger. The end face of the latter is inclined at a wedge locking angle. Additional means having a wedge locking angle are provided to prevent movement of the second plunger in a direction away from the key.
