Description

Technical Field

[0001] The utility model belongs to the technical field of air-floating guide rails, in particular to a multi-axial air-floating motion guide rail device. Background Art

[0002] The air bearing guide is a guide based on the dynamic and static pressure effects of gas, which can achieve smooth movement without friction and vibration.

[0003] An air-floating guide rail is usually composed of a guide rail and a gas supply system. The working principle of the air-floating guide rail is to use the buoyancy of the gas to support the slider, so that the slider can suspend and move on the guide rail. When the gas is compressed and injected into the guide rail, a gas layer will be formed between the guide rail and the slider. This gas layer will generate buoyancy, allowing the slider to suspend and move on the guide rail. In the existing air-floating guide rail technology, the gas is blown onto the guide rail through a single air hole set on the slider to make the slider suspend. When the air-floating guide rail uses a single air hole, an air hammer phenomenon may occur, affecting the smooth operation of the air-floating guide rail.

[0004] To this end, the utility model provides a multi-axial air-floating motion guide rail device. Utility Model Content
