Abstract
The invention provides a device for actuating a clamping tool means by fluid pressure and for monitoring the fluid pressure, which comprises a carrier for a workpiece and the clamping tool means, a first mounting element on the carrier, a second mounting element, and means for detachably coupling the second mounting element to the first mounting element. A pressure fluid conduit system is connected to a fluid pressure generator and includes a first fluid pressure conduit in the first mounting element, a second fluid pressure conduit in the second mounting element, detachable connections between the first and second fluid pressure conduits, the detachable connection in the first fluid pressure conduit including a check valve retaining the fluid pressure in the first fluid pressure conduit when the second fluid pressure conduit is detached, and a third fluid pressure conduit connecting the first fluid pressure conduit to the clamping tool means. A push-button switch including a switching element is in direct communication with the first fluid pressure conduit and is responsive to a predetermined decrease in the fluid pressure retained therein, and a pressure signal generator is opera…
