The terms "first", "second", etc. in the specification and claims of the present invention or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order.
[0018] Reference to "embodiments" in the present invention means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it mutually exclusive, independent, or alternative to other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present invention may be combined with other embodiments.
[0019] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.
[0020] like Figure 1-3 As shown, an air-floating slide rail module includes a slider 1 and a guide rail 2. The slider 1 is limitedly connected to the guide rail 2. The slider 1 can slide on the guide rail 2, and the slider 1 and the guide rail 2 are matched with each other. A plurality of air outlet holes 3 are provided on the side wall of the guide rail 2 that matches the slider 1. The guide rail 2 is provided with an air inlet hole 4 and a gas channel 5. The air inlet hole 4 is used to connect to an external air source, and the gas channel 5 is connected to the air inlet hole 4 and the air outlet hole 3 respectively. During operation, the air inlet hole 4 is connected to an external high-pressure air source, and the high-pressure gas flows into the gas channel 5 through the air inlet hole 4, and then flows into the air outlet hole 3 through the gas channel 5, and flows out through the air outlet hole 3 and blows toward the slider 1, thereby forming a layer of air film between the matching surfaces of the guide rail 2 and the slider 1, so that the guide rail 2 and the slider 1 will not be in direct contact, reducing the wear of the slider 1 during the sliding process, and extending the service life; it can effectively avoid the problem of inaccurate guidance due to wear, so that it can meet the high-precision and high-standard processing requirements.
[0021] The side walls of the guide rail 2 and the slider 1 are provided with a plurality of limit connection holes 6, which are provided to facilitate the installation of the air-floating slide rail module. Specifically, when the air-floating slide rail module is installed on a certain automation equipment, the slider 1 and the guide rail 2 can be installed on the equipment by screwing screws into the limit connection holes 6.
[0022] Porous ceramic blocks 7 are respectively installed on the air outlet holes 3, and the porous ceramic blocks 7 extend to the mating surfaces of the guide rail 2 and the slider 1. In order to form a stable air film on the mating surface between the guide rail 2 and the slider 1, it is necessary to open enough air outlet holes 3 on the side walls where the guide rail 2 and the slider 1 are matched, and the smaller the aperture of the air outlet holes 3, the better. The porous ceramic blocks 7 have the characteristics of high porosity and high strength. By blocking the air outlet holes 3 with porous ceramic blocks 7, the processing difficulty can be reduced. There is no need to open many air outlet holes 3 or air outlet holes with very small apertures. By installing porous ceramic blocks 7 on the air outlet holes 3, a stable air film can be formed on the mating surface of the guide rail 2 and the slider 1 during operation.
[0023] In this embodiment, a V-shaped inclined surface 8 is provided on the side of the guide rail 2 close to the slider 1, and the air outlet 3 is symmetrically arranged on the two side walls of the V-shaped inclined surface 8. A V-shaped groove 9 adapted to the V-shaped inclined surface 8 is provided on the side of the slider 1 close to the guide rail 2. Through the cooperation of the V-shaped inclined surface 8 and the V-shaped groove 9, the slider 1 and the guide rail 2 can be fixed by clamping, thereby improving the stability of the structure. In other embodiments, the matching surface of the guide rail 2 and the slider 1 can also be any other shape that can achieve clamping and limiting, such as: C-shaped, T-shaped, dovetail groove shape or I-shaped, etc.
[0024] An air intake connector 10 is provided on the air intake hole 4, and an air pipe 11 is installed on the air intake connector 10. The air pipe 11 is connected to an external high-pressure air source. During operation, the external air source transports the high-pressure gas to the air intake connector 10 through the air pipe 11, and then injects the high-pressure gas into the gas channel 5 in the guide rail 2 through the air intake connector 10, and then blows it out through the porous ceramic block 7, thereby forming a layer of air film between the V-shaped slope 8 and the V-shaped slide groove 9.
[0025] In order to improve the stability of the air film, in the present embodiment, air inlet holes 4 are respectively provided at both ends of the guide rail 2, so that during operation, both ends of the guide rail 2 can take in air at the same time, thereby improving the air intake efficiency, thereby enhancing the stability of the air film formed between the V-shaped slope 8 and the V-shaped slide groove 9, and ensuring the clearance sliding fit between the slider 1 and the guide rail 2.
[0026] The air-floating slide rail module can be used on any device that requires sliding fit, thereby improving the fit between the moving parts and the guide parts, reducing friction, and effectively extending the service life, making it suitable for high-precision and high-standard processing requirements.
[0027] The above-mentioned specific implementation mode is a preferred implementation mode of the present utility model, and is not intended to limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to the specific implementation mode. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
