ABSTRACT:
A fixturing device, usable with various fixturing components as a universal modular fixturing system, has a slot and a shaft, the slot and the shaft intersecting and having a common plane of symmetry, the fixturing device having a plurality of transverse bores intersecting the slot and the shaft, perpendicular to the plane of symmetry. The fixturing device is used according to one or more of three clamping techniques. The first clamping technique is back-clamping in which a workpiece having a threaded recess is clamped by a bolt from the back of the slot. The second clamping technique is relocatable clamping in which a clamp support supporting a clamp clamping a workpiece is displaceable along the shaft. The third technique is lever-arm clamping in which a lever arm, pivotally mounted on a pin located in one of the transverse bores, is rotated to clamp a workpiece. The fixturing device also has an array of threaded recesses for attaching a fixturing component, an array of accurately positioned bores for locating a fixturing component and a groove for aligning a fixturing component.
