  • Patent number: 4609002
    Abstract: An automatic set-up system is provided for setting up on a pallet work to be machined by a flexible manufacturing system automatic machine tool. The pallet has a support plate and a jig plate which overlies the support plate on which the work is placed. The support plate, the jig plate and the work are sequentially conveyed by a convey unit on a setting table. The relative positions of the support plate and the jig plate, and of the jig plate and the work are usually held constant by the engagement of positioning recesses and positioning pins. Even if the position of the jig plate or the work conveyed by the convey unit deviates from a predetermined position, a float base and a support plate (the float base, the support plate, and the jig plate) are floated by means of air bearing pads. The horizontal movement of these components can be readily controlled, so that positioning pins can be easily fitted in the positioning recesses.
