Abstract

The invention discloses an II-type gas static pressure guide rail for horizontal use. Guide rail fixing stations are arranged on brackets at two ends; six air flotation blocks in triplet are symmetrically fixed at the upper end, the left end and the right end of an II-type workbench respectively; the air flotation blocks are matched with the upper surface, the left side and the right side of the guide rail fixing stations respectively to form the II-type gas static pressure guide rail for horizontal use; grating rulers are arranged at the central positions of the lower surfaces of the guide rail fixing stations; one end of a ball screw is connected with a motor arranged on one bracket through a coupling, and the other end of the ball screw is connected with the other bracket; and a guide rail workbench and the ball screw are connected through two groups of metallic flexible connectors in pairs. The II-type gas static pressure guide rail of the design has the advantages of high moving precision, low vibration and convenience for processing and assembly, and is applicable in the ultra-precise gas static pressure guide rail field.

Description

technical field [0001] The invention relates to a gas static pressure guide rail, in particular to a Π-type gas static pressure guide rail for horizontal use. Background technique [0002] With the vigorous development of the equipment manufacturing industry, microelectronic equipment, ultra-precision machine tools and instrument technology have become the core technology of international business competition, and are currently the focus and hot issues that various scientific research institutions are competing to study. Among them, the guide rail is one of the basic core technologies in the field of ultra-precision measurement. Due to the advantages of low friction, smooth movement, high precision and almost no thermal deformation, gas hydrostatic lubrication has become an important research object in the field of ultra-precision machining and measurement. . [0003] The traditional aerostatic guideway designs mainly include square, trapezoidal, and triangular forms. Among...
