摘要: 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.

摘要: In a press, a platen has opposed fluid, preferably hydraulically, actuated clamp blocks thereon. Each block functions to register with an open-ended slot in a tool mount plate and upon translation of the block to enter an offset slot section in a clamped or locked relationship. The offset slot sections are opposed one another, wedge-shaped, and complementary to block configuration. The tool mount plate can be quickly and conveniently attached and aligned or removed from the platen as needed.
