ABSTRACT:
An apparatus for locating a workpiece on a processing surface includes a first locator arm assembly, a second locator arm assembly, and a pivotal member. The first locator arm assembly includes a first surface disposed for lateral movement and mating engagement with a first portion of the workpiece. The second locator arm assembly includes a second surface disposed for lateral movement parallel to the first surface, the second surface further for mating engagement with a second, opposite side, portion of the workpiece. Lastly, pivotal member is disposed for pivotal movement about a pivot point and symmetrically coupled, with a zero tolerance buildup, between the first locator arm assembly and the second locator arm assembly for inducing an equal but opposite lateral movement in the first and second mating engagement surfaces of the first and second locator arm assemblies, respectively, whereby the workpiece is accurately located on the processing surface between respective first and second mating engagement surfaces as the surfaces are moved towards one another.
