The horizontal air floating members 31 are arranged on the bottom horizontal side wall of the measuring slider 21, and the horizontal air floating members 31 are arranged horizontally with the top wall of the slide rail 11. The horizontal air floating members 31 comprise horizontal air floating plates 311 arranged on the bottom wall of the measuring slider 21 opposite to the top wall of the slide rail 11, the horizontal air floating plates 311 are arranged in multiple and fixed by fixing bolts, the multiple horizontal air floating plates 311 are provided with uniformly distributed horizontal air floating holes 312, and the horizontal air floating members 31 further comprise horizontal air floating pipes 313 communicating the horizontal air floating holes 312. One side of the base 1 is provided with an air floating machine for providing air floating gas, and the multiple horizontal air floating pipes 313 are connected to the air floating machine through pipelines, so that the air floating machine introduces gas into the horizontal air floating pipes 313, the gas flows to the horizontal air floating holes 312 through the horizontal air floating pipes 313, and the gas sprayed in the horizontal air floating holes 312 is sprayed on the top wall of the slide rail 11, so that the whole measuring slider 21 is suspended above the slide rail 11 under the pushing of the gas, and in the process of pushing the measuring slider 21, since the bottom of the measuring slider 21 is not in contact with the top of the slide rail 11, there is no abrasion phenomenon, so that the overall measurement accuracy of the whole measuring machine is guaranteed.

[0035] Reference Figures 2 to 4 , the vertical air floating members 32 comprise air floating nozzles 321 arranged on the side wall of the inner groove 22, the air floating nozzles 321 are provided with mounting holes 329 for the air floating nozzles 321 to pass through on the side wall of the measuring slider 21, the air floating nozzles 321 comprise piston air blocks 324 and vertical air floating plates 322, the piston air blocks 324 are arranged in the mounting holes 329, the piston air blocks 324 are integrally formed with the vertical air floating plates 322, and the side wall of the vertical air floating plates 322 is provided with multiple uniformly distributed vertical air floating holes 323, and the vertical air floating members 32 further comprise vertical air floating pipes for connecting the air floating machine, the vertical air floating pipes are connected to the air floating machine through pipelines, so that the gas flows into the piston air blocks 324 through the vertical air floating pipes, and then the gas is sprayed from the vertical air floating holes 323 arranged on the vertical air floating plates 322, so that the stability of the whole measuring slider 21 on the slide rail 11 is improved, and the slide rail 11 can only move along the length direction of the slide rail 11.
