Multi-shaft supporting air floatation platform

The invention discloses a multi-shaft supporting air floatation platform, and belongs to the technical field of extremely-precise instrument equipment platforms. The multi-shaft supporting air floatation platform aims to solve the problems that the prior supporting platform is limited in leveling state and narrow in application range, and comprises a bearing platform, M supporting legs, M air floatation barrels and M air feet, wherein M equals 3 or 4 or 5 or 6 or 7 or 8, the bearing platform is a circular platform and is supported by the M supporting legs, and an M-edge shape is formed by the M supporting legs and M connecting points on the lower surface of the bearing platform. The tail end of each supporting leg is connected with an air floatation barrel, and the bottom end of each air floatation barrel is connected with an air foot through an air flotation ball bearing. The multi-shaft supporting air floatation platform serves as a supporting platform.
