ABSTRACT:
A modular fixturing system is provided, whose typical use is holding each of a series of similar workpieces, such as rough castings, during machining. It is conventional to support such workpieces during machining on permanent fixtures, specially designed for each type and size of workpiece, each such fixture utilizing two or more locating pins through parallel bores in the workpiece. In the present invention, locating pins are not part of any permanent fixture; instead, using a fixturing plate drilled with bores at modular intervals, the present adaptors are secured at any required spacing, and locating pins of desired diameter are mounted in them. One of the adaptors, referred to as "fixed", is mounted directly to one of the modular bores of the fixturing plate. The other adaptor to be used will be one whose position is slidably adjustable along linearly aligned slots in its base. Diamond-shaped locating pins may be used in either type of adaptor, provisions being made for their securement at desired angularity.
