Abstract
The invention relates to a static pressure air flotation unit and a processing method based on pouring molding, which belong to the field of static pressure air flotation. The invention solves the problems of poor gap passage capacity of the small-hole throttling air flotation unit, eddy current interference, and low structural strength when the integral porous air flotation unit is used as a static pressure air flotation working surface, and the environment is polluted by falling powder. The static pressure air flotation unit includes a lower opening shell and an air supply interface; the lower opening shell is filled with a pouring body, and the lower end surface of the lower opening shell is flush with the lower surface of the pouring body, and N fine pores are densely distributed in the pouring body, and There is also an air guide hole on the pouring body, the air guide hole is connected with the fine air hole, one end of the air supply interface is set in the air guide hole, and the other end protrudes to the outside of the lower opening shell, and the air supply interface communicates with the fine air hole in the casting body . The present invention is mainly used to realize static pressure air flotation.
Description
technical field [0001] The invention belongs to the field of static pressure air flotation. Background technique [0002] As a kind of gas lubrication technology, hydrostatic air flotation technology is widely used in the fields of precision servo, high-precision transmission and precision instruments. Static pressure air flotation technology is usually applied between two parts that move relatively. Through the principle of small hole throttling, a high-pressure air film is formed between the two parts, and the two parts that are relatively moving are separated by the air film. , to achieve non-contact relative movement. Therefore, when the static pressure air flotation technology is used, except for the gas viscous damping, it can be considered that there is no friction between the relative moving parts, and the precise motion control of the relative moving parts can be realized through a weak control force. [0003] Generally, small hole throttling technology or porous ...
