Structure Design and Analysis of Two-Dimensional Aerostatic Motion Platform Based on Box Plate

Abstract

In the current study of two-dimensional aerostatic motion platform, there are problems such as poor uniaxial motion straightness, poor two axis verticality accuracy and small bearing capacity. In this study, a two-dimensional aerostatic motion platform with precision box plate as its structural reference was designed. It is designed with integral aerostatic guideways, and all components are based on precise granite box plate. It uses the high planeness, parallelism and perpendicularity of the precise granite box plate itself to ensure the linear accuracy of the moving guide and the perpendicularity between the two moving guides. And the aerostatic motion platform is driven by linear motor, which eliminates the error caused by traditional mechanical transmission. This two-dimensional air floating platform features high stability, high motion straightness, easy installation and maintenance, and can be widely used in precision machining and precision measurement.
