Composite closed type static pressure guiding rail workstation

Abstract

The invention discloses a working platform for a composite closed type hydrostatic guide rail. An axial supporting device comprises an axial upper thrust plate fixedly connected with a turntable; the lower part of the axial upper thrust plate is provided with an axial hydrostatic support fixedly connected with a lathe bed; the lower part of the axial hydrostatic support is provided with an axial lower thrust plate fixedly connected with the axial upper thrust plate; the lower part of the axial upper thrust plate is provided with a guide rail soft belt layer which is connected with the axial hydrostatic support; and oil cavities are arranged between the soft belt layer and the axial hydrostatic support, and between the axial hydrostatic support and the axial lower thrust plate respectively. A radial supporting device comprises a radial bearing liner fixedly connected with the turntable; the outside of the radial bearing liner is connected with a radial hydrostatic support; and an oil cavity is arranged between the radial bearing liner and the radial hydrostatic support. A driving device is a motor, and the oil cavity is communicated with an oil supply system through a restrictor. The working platform is suitable to serve as a rotary working platform for a digital control machine tool with complex functions.

Description

technical field [0001] The invention relates to a static pressure guide rail workbench, in particular to a composite closed static pressure guide rail workbench. Background technique [0002] With the rapid development of CNC machine tool technology, the requirements for worktables required by CNC machine tools are getting higher and higher, and the demand for large workbenches is also increasing, with higher precision requirements and better reliability. , and requires environmental protection and low energy consumption. Generally speaking, the support of the workbench has the following types: The traditional sliding guide rail workbench relies on the metal sliding guide rail surface as the rotating support, and the friction coefficient of the metal sliding guide rail surface is relatively high, so the driving power is required to be large, it will generate heat, and cannot rotate at a high speed. , high energy consumption; the traditional rolling bearing table, the precis...

Generally speaking, the support of the workbench has the following types: The traditional sliding guide rail workbench relies on the metal sliding guide rail surface as the rotating support, and the friction coefficient of the metal sliding guide rail surface is relatively high, so the driving power is required to be large, it will generate heat, and cannot rotate at a high speed. , high energy consumption; the traditional rolling bearing table, the precision can not reach a very high state, and the bearing wear will lose the rotation accuracy, and the price of large bearings is relatively expensive; the traditional static pressure table has relatively high requirements on the environment, and there is oil leakage phenomenon, will pollute the environment, and has specific requirements for use, and does not have compound functions. However, CNC machine tools, especially large-scale CNC machine tools, are developing in the direction of compound processing, which requires workbenches with compound function guide rails.
