Abstract

The invention relates to an adjusting mechanism of a precise air-floatation operating platform. The adjusting mechanism of the precise air-floatation operating platform comprises a bearing cap (1), a base (2), a rotary disk (3), a stepped shaft (4) and the like, wherein the base (2) is arranged on a loading platform, the rotary disk (3) is arranged on the stepped shaft (3), and the bearing cap (1) is arranged on the base (2) through a screw nail. An H-type closed type air-floatation guide rail structure is applied to the precise air-floatation operating platform. The H-shaped closed type air-floatation guide rail comprises two Y-axis moving modules and an X-axis moving module. The symmetrical structure has a better dynamics performance and achieves high-precision location and moving of the operating platform.

Description

technical field [0001] The invention relates to a sliding guide rail, in particular to a high-precision air-floating workbench adjustment mechanism driven by a linear motor Background technique [0002] The guide rails generally used in engineering are mainly divided into three types: sliding type, rolling type and static pressure type. The sliding friction between the moving pairs of the sliding guide rail is usually made of cast iron. Due to the large difference in the dynamic and static friction coefficients of the cast iron, it is easy to crawl, and it is easy to bite and wear, so the service life is not long, so Sliding guide rails are rarely used in the design of high-precision workbenches. The rolling guide rail adopts steel balls and rollers as the rolling bodies, and the difference between the dynamic and static friction coefficients is very small. At the same time, it has a small friction coefficient and will not cause crawling. However, due to the point contact ...
