Integrated fluid hydrostatic pressure nut main driving type lead screw pair linear feeding unit

The invention discloses an integrated fluid hydrostatic pressure nut main driving type lead screw pair linear feeding unit. According to the technical scheme, the integrated fluid hydrostatic pressurenut main driving type lead screw pair linear feeding unit comprises a hydrostatic pressure lead screw and a fluid hydrostatic pressure guide rail which are parallel to one another, a nut assembly isaxially installed on the hydrostatic pressure lead screw, and a hollow motor is installed on one side of the nut assembly. The nut assembly is installed below a workbench through a supporting frame, and the workbench is detachably connected with the fluid hydrostatic pressure guide rail. The outer side of the supporting frame is coated with an oil collecting plate to form an oil collecting space.The hydrostatic pressure lead screw is installed above a base, and the base is provided with a plurality of oil discharging grooves used for discharging oil for the fluid hydrostatic pressure guide rail and the oil collecting p
