Hydromechanical clamping device

摘要

A clamping device includes a base body defining at least a portion of at least one pressure chamber, which has at least one opening oriented in a direction of action. A membrane is connected with the base body in a pressure-tight manner and seals the at least one opening in the direction of action. The membrane defines a first side wall section of the pressure chamber. A movable second side wall section partially delimits the pressure chamber and a constant amount of pressure fluid is sealed in the pressure chamber. At least one mechanical actuator displaces or deforms the second side wall section in order to cause the membrane to outwardly bulge.

主权项

1. A clamping device comprising:
a base body defining at least a portion of at least one pressure chamber, the base body having at least one opening oriented in a direction of action, the at least one opening including a step oriented in the direction of action, a plate having a first surface exposed at the outside of the base body and a second surface facing into the at least one pressure chamber, the plate having a periphery on the step and being fixedly connected with the base body in a pressure-tight manner and sealing the at least one opening in the direction of action, the membrane defining a first side wall section of the pressure chamber, a movable second side wall section partially delimiting the pressure chamber, a constant amount of pressure fluid sealed in the pressure chamber, and a mechanical actuator configured to move the second side wall section towards the pressure chamber.
