Embodiment Construction
[0037] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0038] Such as figure 1 As shown, the present invention is a pneumatic guide rail, which includes a guide rail 2 and a sliding bracket installed on the guide rail 2 , and the sliding bracket includes a supporter in contact with the guide rail 2 . A support block is fixed by screws in the support groove 1, and the support block includes an upper plate 3 and a lower plate 4, and the upper plate 3 and the lower plate 4 are arranged in a linear array with semicircular grooves in cross section. Groove, the corresponding two grooves between the upper plate 3 and the lower plate 4 form a rotating groove 7, and the upper plate 3 and the lower plate 4 are fixedly conn...

The invention relates to a pneumatic guide rail. The guide rail comprises a guide rail body and a sliding bracket installed on the guide rail body, the sliding bracket comprises a supporting device making contact with the guide rail body, and the supporting device comprises a supporting block. The guide rail is characterized in that the supporting device comprises the supporting block, multiple cylindrical rotating grooves in a linear array are formed in the supporting block, roller pin rollers are embedded in the rotating grooves, an opening A is formed in the top of each rotating groove, the roller pin rollers make contact with a rack plate through the openings A, an opening B is formed in the bottom of each rotating groove, the openings B of all the rotating grooves are connected with an air source through an air guide channel, an air guide gap is formed between each roller pin roller and the inner wall of the corresponding rotating groove, and under the combined action of the air source pressure and the rack plate, the roller pin rollers are suspended in the middles of the rotating grooves. The supporting device is supported by the roller pin rollers driven by air flow, under the driving of the air flow, the friction force of the roller pin rollers is approximate to zero, and the roller pin rollers have high sliding smoothness.
Description
technical field [0001] The invention relates to a pneumatic guide rail, which belongs to the guide rail mechanism of precision processing machinery. Background technique [0002] As a supporting device for directional movement, guide rail is widely used in various machine tool fields; [0003] Guide rails are generally divided into dry grinding type, ball type, and high-pressure gas or liquid suspension support type in direct contact with the sliding surface; [0004] Among them, the dry grinding type guide rail mainly reduces the friction between the guide rail surfaces by setting grease or lubricating oil between the two guide rail surfaces, so as to realize the sliding of the guide rail mechanism. Once the bearing capacity of the guide rail mechanism is too high, it will be damaged. The thickness of the oil film is reduced, the friction is increased, the sliding efficiency of the guide rail is reduced, and the sliding smoothness of the guide rail is affected, thereby aff...
