ABSTRACT:
An apparatus is disclosed which facilitates rapid insertion, removal and exchange of a fixture in situations where it must be securely attached to a support surface before or after removal from such surface. The fixture has a plurality of studs extending outwardly therefrom which guide the fixture tool through channels in a support surface and into placement in respective slots of T-slot clamps which are moved by fluid pressure to the open position, the fixture transferred, and the fluid pressure released to effect clamping. The present invention can be used in a high production manufacturing system such as a press or molding operation and is particularly useful in thermoforming operations.
