Air floating component based on porous material and platform

Abstract

The invention provides an air floating component based on a porous material and a platform. The air floating component comprises an air chamber upper cover, a pipeline joint, an air chamber shell and a porous module, wherein the air chamber upper cover is connected to the upper end of the air chamber shell; the porous module is arranged at the inner side of the air chamber shell; the porous module is connected to the inner wall surface of the air chamber shell to form an air cavity between the porous module and the air chamber upper cover; the pipeline joint is communicated with the air cavity through the air chamber upper cover; and the porous module is provided with multiple guide holes communicated with the upper surface and the lower surface of the porous module. A porous material is adopted to manufacture a throttle part, serving as the air flowing component, of the porous module, so that the noise under high-pressure and high-speed airflows can be eliminated, the silence of working environment is guaranteed, and the bearing capacity of the air floating component and the air floating stability are enhanced.

Description

technical field [0001] The invention relates to an air flotation component, in particular to an air flotation component and a platform based on porous materials. Background technique [0002] With the development of gas lubrication technology, the air flotation platform is widely used in occasions and tests that need to offset gravity due to its low friction, high cleanliness, long life, and high motion accuracy. However, the air flotation platform has noise during use. The shortcomings of large size and low load limit its use in occasions that require a quiet working environment and high load. [0003] Traditional air-floating platforms generally adopt technologies such as small hole throttling, annular throttling or slit throttling. They are characterized by simple processing technology, but when the air supply pressure changes, it is easy to produce whistling phenomenon and the sound is sharp. , and the carrying capacity also fluctuates, it is not suitable for use in a q...
