Abstract: A fixture is provided for locating a workpiece in space including a blade having a longitudinal axis, a bottom edge, a top edge, and a plurality of through-bores. At least two of the through-bores are positioned on the blade to define a predetermined location relative to the top and bottom edges, and together with a riser, allow for the precise positioning of a locating pin, or other datum point locator, that may be attached to the blade. The blade also includes a mounting arm that is eccentrically located on a top edge. The mounting arm has a plurality of through-bores, where at least two of the through-bores define a predetermined location relative to the top edge. A locating pin, or other datum point locator is attached to the mounting arm.

Abstract: The a modular system for locating and clamping a workpiece in space is provided that includes positioning blade including a riser mount having a plurality of first mounting-bores and a plurality of first positioning-bores. A clamp mount is provided on the blade that includes a plurality of second mounting-bores and a plurality of second positioning-bores. The first positioning-bores have a predetermined positional relationship to the second positioning-bores. A locator arm is also provided on the blade, and has a plurality of third positioning-bores where the third positioning-bores comprise a predetermined position relative to the first positioning-bores and the second positioning-bores. A system for positioning and clamping a workpiece is also provided that includes in combination the foregoing positioning blade mounted on structure for elevating the workpiece, e.g., a riser, and structure for clamping the workpiece.
