Walking device based on air floatation sliding

The invention relates to the technical field of precision trusses, and especially relates to a walking device based on air floatation sliding. The technical scheme adopted by the device is as follows:the device comprises X-axis cast iron supporting and stabilizing frames which are spliced in the left-right direction to form a combination, the lower ends of every two adjacent X-axis cast iron supporting and stabilizing frames are combined together through a splicing and combining supporting connecting piece, an X-axis granite guide rail body is arranged at the upper ends of the X-axis cast iron supporting and stabilizing frames, an X-axis body sliding structure assembly capable of sliding in the length direction is assembled on the X-axis granite guide rail body, and a linear motor rotor structure is arranged on the front face of the X-axis body sliding structure assembly. The device has the following advantages: a brand-new structural design is adopted, the problems of incoherent movement, low repeated positi
