Slider type hydrostatic guideway series with the same installation dimensions as the linear roller guideway

Abstract

The invention discloses a sliding block type static pressure guide rail series having the same installation size with a pin roller linear guide rail, and belongs to the field of standard parts of a machine tool. The sliding block type static pressure guide rail series comprises a special-shaped guide rail installed on a machine body, a quantitative dividing block (or a constant pressure type throttling block) installed on a movable sliding board, a static pressure sliding block, an oil drainage block (or a throttling block) and a sealing framework. An oil dividing block (or a throttling block) is installed at one end of a sliding block to divide pressure oil; the oil drainage block is installed at the other end of the sliding block to collect static pressure return oil to an oil absorption pump; the sealing framework is installed among the oil dividing block (or the throttling block), the oil drainage block and the sliding block, and used for sealing the static pressure sliding block and the guide rail; the pressure oil is communicated with the oil absorption pump through the oil drainage block to form a closed type pressure oil recovery system, and the state that pressure oil of a traditional static pressure guide rail is drained outwards in an opened mode is changed. The use and installation size of the sliding block type static pressure guide rail series is the same as that of the pin roller linear rolling guide rail developed in recent ten years, an integrated series product is formed, and conditions are created for upgrading various mechanical guide rails.

Description

Technical field [0001] The invention relates to the field of standard parts and components used in various machine tools, especially high-precision and heavy-duty machine tools, and is especially related to a standardized, serialized, and universal static pressure guide rail. Background technique [0002] The roller linear guide (slider type) developed in the past ten years has been widely used in medium and large high-precision machine tools. This guide has formed a standardized, serialized and generalized product, but this kind of guide has inherent defects. The linear motion of the rolling elements is poor in vibration absorption, and there is a difference between static friction resistance and dynamic friction resistance, which affects the accuracy of the machine tool to a certain extent, especially on the machine tool with large cutting force changes and frequent speed changes. degree. Therefore, many machine tool manufacturers are designing and manufacturing hydrostatic gu...

Problems solved by technology

However, due to the self-manufacturing of machine tool factories, there are various structural forms, which cannot be standardized, and the performance varies greatly, which seriously hinders the promotion and improvement of static pressure technology, and affects the improvement of my country's machine tool level to some extent.
