ABSTRACT:
A fixture for accurately locating a workpiece during machining operations. A table includes a plurality of frusto-conical openings arranged in a grid pattern to receive locator pins each having a frusto-conical base to seat closely in the opening in which it is inserted. The locator pins establish stops against which some parts of the workpiece are positioned. The workpiece is held against the pins by power cylinders carried on special pegs that can be inserted in the table openings. Air for operating the cylinders is made available to each opening through a valved line and a passageway extending to each opening in the table. Each peg has a passage arranged to receive the incoming fluid from the opening and to transmit the air to its cylinders to extend them against the workpiece.
