Hydrostatic support head and hydrostatic support device for mirror-image milling for aircraft skin

The invention discloses a hydrostatic support head for mirror-image milling for an aircraft skin. The support head comprises a support part and a connection part connected with the lower end of the support part, wherein the upper surface of the support part is provided with one or more liquid grooves, one or more air grooves and pressure measurement holes as many as the liquid grooves; and a flow channel I communicating with the liquid grooves, a flow channel II communicating with the air grooves, and a pressure measurement flow channel communicating with the pressure measurement holes are arranged in the support head. The invention further discloses a hydrostatic support device for mirror-image milling for an aircraft skin. Compared with the prior art, the hydrostatic support head and the hydrostatic support device, which are disclosed by the invention, have the advantages of being high in skin machining accuracy, high in machining quality, high in machining stability, simple in structure, easy to realize, and the like.
