Abstract
The utility model relates to a sliding block type hydrostatic guide rail identical to a pin roller linear guide rail in installation dimension and belongs to the field of machine tool standard components. The sliding block type hydrostatic guide rail identical to the pin roller linear guide rail in installation dimension comprises a specially-shaped guide rail body installed on a machine body. A quantitative type oil distributing block (or a constant-pressure type throttling block), a hydrostatic sliding block, an oil discharging block (or a throttling block) and sealing frames are installed on a movable sliding board. The quantitative type oil distributing block (or the constant-pressure type throttling block) is installed at one end of the hydrostatic sliding block so that pressure oil can be distributed and the oil discharging block is installed at the other end of the hydrostatic sliding block so that hydrostatic return oil can be collected to an oil suction pump. The sealing frames are installed between the quantitative type oil distributing block (or the constant-pressure type throttling block), the oil discharging block and the hydrostatic sliding block, so that the hydrostatic sliding block and the guide rail body are sealed. The pressure oil is communicated with the oil suction pump through the oil discharging block, so that a pressure oil closed recovery system is formed. The state that pressure oil of a traditional hydrostatic guide rail is discharged outside in an open mode is changed. The installation dimension of the sliding block type hydrostatic guide rail is identical to that of the pin roller linear guide rail developed in the recent ten years, so that a complete series of products are formed and conditions are created for renewal and upgrading of various mechanical guide rails.
