Abstract

The invention discloses a gas lubrication and friction damping composition type high-rigidity and high-stability two-dimensional adjusting workbench and belongs to the technical field of precise instruments and machines. An X-direction gas floatation sliding plate is configured between a base and a Y-direction gas floatation sliding plate; a supporting gas film is formed between a gas flotation working face x5 on the X-direction gas flotation sliding plate and a gas flotation working face y3 on the Y-direction gas floatation sliding plate to support the Y-direction gas flotation sliding plate; a supporting gas film is formed between a gas flotation working face z on the base and gas flotation working faces x3 and x4 on the X-direction gas floatation sliding plate to support the X-direction gas flotation sliding plate; guide rails A and B parallel to each other are fixedly mounted on the gas flotation working face z of the base; guide rails C and D parallel to each other are fixedly mounted on the X-direction gas flotation sliding plate; a friction damping unit E1 is in contact fit with the guide rail A and the guide rail B; a friction damping unit E2 is in contact fit with the guide rail C and the guide rail D. The invention provides a precise plane two-dimensional adjusting device with high rigidity and high positioning stability.

Description

technical field [0001] The invention belongs to the technical field of precision instruments and machinery, and in particular relates to a gas lubrication and friction damping compound type two-dimensional adjustment workbench with high rigidity and high stability. Background technique [0002] In recent years, as the advanced equipment manufacturing industry is gradually developing towards precision and ultra-precision, especially the continuous improvement of aero-engine performance, the precision requirements for engine processing and assembly are getting higher and higher, especially when pursuing a higher thrust-to-weight ratio. , the impact of engine vibration, noise and other factors on performance due to assembly errors has gradually become prominent. This poses a severe challenge to the performance of the engine's test equipment, and thus has higher requirements for the performance of the adjustment and positioning workbench used. [0003] In 2000, the friction dri...
