Embodiment Construction

[0011] The structure and working principle of the T-shaped guide rail will be described below in conjunction with the accompanying drawings. Example 1, see figure 1 , where 1 is the granite bed, 2 is the left pressure plate, 3 is the cast iron sliding plate, 4 is the flow controller group, 5 is the horizontal static pressure block, 6 is the vertical static pressure block, and 7 is the right pressure plate. Among them, the horizontal static block see figure 2 As shown, the X axis is installed horizontally, and the quantity is 2 in total. Vertical static pressure block, installed vertically in X-axis, 3 pieces on one side, 6 pieces in total.

[0012] Working principle: Through the flow controller group 4, a certain pressure of lubricating oil is input into the static pressure chambers of the guide rails (the sliding plate 3 guide rail mating surface), forming a bearing oil film with a certain bearing capacity, floating the moving guide rails, and realizing guide rail pairing ...

Abstract

The invention discloses a T-shaped hydrostatic guide rail for a precision finishing machine tool, which belongs to the field of advanced manufacturing and is a structural improvement on the traditional hydrostatic guide rail. In respect of materials, the machine tool body is made of granite, and a slide carriage is made of cast iron; in respect of the structural form, a specific T-shaped guide rail form is adopted, i.e. the machine tool body is provided with a T-shaped guide rail groove matched with a moving guide rail; in respect of hydrostatic control, a flow controller group conveys lubricating oil to each static pressure cavity on the guide rail; static pressure blocks are mounted in the horizontal direction and vertical direction respectively; and the adjustment of the oil film thickness between guide rails is realized by adjusting the static pressure blocks. The hydrostatic guide rail adopting the T-shaped structure has high rigidity, high guide ratio and high precision.

Description

technical field [0001] The invention belongs to the field of advanced manufacturing, and is an improvement to the structure of the traditional hydrostatic guide rail for precision machining machine tools. The application of the improved guide rail structure can realize the high rigidity, high guide ratio and high precision of the motion of the guide rail pair. Background technique [0002] Hydrostatic guideway, as a form of guideway widely used in precision ultra-precision machine tools, its working principle is as follows: lubricating oil with a certain pressure is input into the oil chamber on the guideway surface through the oil hole to form a bearing The pressure will float the moving guide rail, so that a bearing oil film is formed between the two guide rails, and the friction between the guide rail surfaces is in a state of pure liquid. Its main features are: [0003] 1) The guide rail pairs are separated by an oil film, the sliding resistance only comes from the flu...
