Description

A hydraulic cylinder push type machine tool static pressure guide rail workbench

technical field

The utility model belongs to the technical field of machinery and relates to a machine tool, in particular to a static pressure guide rail workbench of a hydraulic cylinder push type machine tool.

Background technique

However, all parts with high precision requirements and finer surface roughness requirements generally need to be final processed by cutting methods on machine tools. Machine tools play an important role in the modernization of the national economy. A workbench is necessary to process parts, and now many machine tools have adopted hydrostatic guide rails to carry the workbench. For the open hydrostatic guideway, the pressure oil enters each oil chamber of the guideway through the restrictor to make the moving parts float, the surface of the guideway is separated by the oil film, and the oil in the oil chamber continuously flows back to the oil tank through the oil sealing edge. When the moving guide rail is displaced downward by the external load, the gap between the guide rails becomes smaller, which increases the oil return resistance and increases the oil pressure in the oil chamber to balance the external load. The processing technology of the open static pressure guide rail is simple, and the operation is also more convenient. The workbench is basically driven by a ball screw, and its processing is complicated, its disassembly is cumbersome, and its processing cost is also relatively high.
