When the gas layer is thick enough, the gas buoyancy supports the air-floating slider 11 and makes it levitate on the guide rail body 1. When the air-floating slider 11 is close to the end of the first buffer 15, the first buffer 15 absorbs the impact of the air-floating slider 11 when it slides. By adjusting the sliding length of the air-floating slider 11 in the guide rail body 1, it can adapt to different working scenes and needs. Whether a longer stroke or a shorter stroke is required, it can be flexibly adjusted, which can effectively reduce unnecessary idle stroke during the sliding process of the air-floating slider 11, and can buffer the air-floating slider 11 according to the sliding stroke of the air-floating slider 11. It can effectively reduce the overshoot of the air-floating slider 11 when it reaches the target position, thereby effectively positioning the air-floating slider 11 accurately, and reducing the impact and vibration caused by the contact between the air-floating slider 11 and the positioning plate 12 through the first buffer 15, effectively reducing the problem of wear or damage to the surface of the air-floating slider 11 caused by the impact force, and effectively improving the overall stability and reliability.

[0024] like Figure 2As shown, a hollow groove 2 is opened in the middle of the positioning plate 12; an air intake pipe 21 is fixedly connected to the side wall of the positioning plate 12; the air intake pipe 21 is fixedly connected near the top of the positioning plate 12; the end of the air intake pipe 21 is arranged at a position corresponding to the hollow groove 2; two first exhaust pipes 22 are fixedly connected to the side wall of the positioning plate 12; the first exhaust pipe 22 is fixedly connected to one end near the first buffer 15; when working, the end of the air intake pipe 21 is connected to one end of the air pump, so that the airflow passes through the air intake pipe 21 into the hollow groove 2, and then enters the first exhaust pipe 22 The air is discharged from the end. When the air-floating slider 11 approaches, the air flow blows toward the surface of the air-floating slider 11. The air flow is discharged from the side of the air-floating slider 11 through the first exhaust pipe 22. This can effectively improve the positioning accuracy of the air-floating slider 11, effectively reduce the problem of the air-floating slider 11 being offset by external disturbances during high-speed movement, effectively reduce the large impact of the air-floating slider 11 when it stops or changes direction, and can generate a force in the opposite direction of the impact force, thereby effectively reducing the impact and vibration of the air-floating slider 11 on the first buffer 15.

[0025] like Figure 1 , Figure 2 , Figure 3 As shown, the side wall of the positioning plate 12 is fixed with two springs 3; the two springs 3 are fixed at the corresponding positions of the hollow groove 2; the spring 3 is fixed to the outside of the corresponding hollow groove 2; the end of the spring 3 is fixed with a second exhaust pipe 31; the second exhaust pipe 31 slides in the middle of the hollow groove 2; the first exhaust pipe 22 has two first exhaust holes 32 in the middle; the second exhaust pipe 31 has two second exhaust holes 33 in the middle; the second exhaust pipe 31 has two guide tubes 34 fixed to the middle of the second exhaust pipe 31; the two guide tubes 34 are fixed at the corresponding positions of the second exhaust holes 33; during operation, when the air-floating slider 11 approaches the end of the hollow groove 2, the side wall first fits with the end of the second exhaust pipe 31, and when the air-floating slider 11 continues to move, the second exhaust pipe 31 The spring 3 slides inside the first exhaust pipe 22. During the movement of the second exhaust pipe 31, the spring 3 is elastically contracted by the pressure of the second exhaust pipe 31. At this time, the first exhaust hole 32 overlaps with the second exhaust hole 33, and the air flow is discharged into the guide pipe 34 through the first exhaust hole 32 and the second exhaust hole 33. The air flow is discharged from the end of the guide pipe 34. The direction of the air flow can be changed by fitting the air floating slider 11 with the end of the second exhaust pipe 31. The air flow is blown to the surface of the guide rail body 1, which can effectively reduce the accumulation of tiny particles and dust on the surface of the guide rail body 1, effectively reduce the interference of impurities and tiny particles on the movement of the air floating slider 11, effectively reduce the problems of inaccurate positioning or increased friction, and effectively maintain the surface of the guide rail body 1 to increase the stability of working operation.

[0026] like Figure 2 and Figure 4As shown, two grooves 4 are provided in the middle of the positioning plate 12; the two grooves 4 are provided at the bottom of the hollow groove 2; a pulley 41 is rotatably connected to the middle of the groove 4; during operation, when the positioning plate 12 is adjusted in position in the middle of the guide rail body 1 and moves, the middle of the pulley 41 fits with the top of the guide rail body 1, so that when the positioning plate 12 moves, the pulley 41 rotates inside the groove 4 along with the positioning plate 12, and the pulley 41 can effectively reduce the wear of the positioning plate 12 when it moves in the middle of the guide rail body 1, and effectively reduce the direct pressure of the pulley 41 on the surface of the guide rail body 1 during the movement of the guide rail body 1, which may cause damage to the guide rail body 1, and effectively make the positioning plate 12 move more smoothly in the middle of the guide rail body 1, effectively reduce the resistance generated when the positioning plate 12 moves, make the positioning plate 12 more stable during the movement, and effectively increase the service life of the positioning plate 12 and the guide rail body 1.

[0027] like Figure 1 As shown, two telescopic rods 5 are fixedly connected to the top of the positioning plate 12; the two telescopic rods 5 are arranged opposite to each other; the ends of the telescopic rods 5 are fixedly connected to the second buffer 51; when working, the telescopic rods 5 are stretched to adjust the height position of the second buffer 51, and when the air-floating slider 11 is close to the end of the first buffer 15 and makes contact, the end of the second buffer 51 simultaneously contacts one side of the equipment on the air-floating slider 11, and the height of the second buffer 51 is adjusted by the telescopic rod 5. The equipment can be effectively buffered by adjusting the height of the second buffer 51, and the equipment on the air-floating slider 11 can be effectively reduced. When the equipment moves at high speed or stops suddenly, the equipment is subjected to a large impact or gravity displacement, which effectively reduces the deviation of the equipment position and reduces the problem of decreased accuracy caused by the gravity displacement of the equipment. The second buffer 51 can effectively absorb and disperse the vibration and jitter generated by the equipment during movement, thereby improving the stability of working operation.

[0028] like Figure 1 and Figure 4 As shown, two sponge blocks 6 are fixedly connected to the middle part of the positioning plate 12; the two sponge blocks 6 are arranged opposite to each other; the sponge block 6 is arranged inside the slide groove 10; during operation, when the positioning plate 12 slides in the middle part of the guide rail body 1, the sponge block 6 slides simultaneously with the positioning plate 12, and the inside of the slide groove 10 is cleaned by the sliding of the sponge block 6. The sponge block 6 has good adsorption and softness, which can effectively remove tiny particles in the inside of the slide groove 10, effectively reduce dust and impurities in the slide groove 10, and effectively reduce the normal operation efficiency of the air floating slider 11 caused by untimely cleaning of dust and impurities. In addition, the soft performance of the sponge block 6 reduces scratches or damages caused by cleaning the inside of the slide groove 10, and effectively increases the performance of the guide rail body 1.

[0029] like Figure 1 and Figure 2As shown, an elastic pad 7 is installed at the end of the first buffer 15; the elastic pad 7 is fixedly connected to the end of the first buffer 15; during operation, when the air-floating slider 11 approaches the end of the first buffer 15, the elastic pad 7 contacts the surface of the air-floating slider 11, and the elastic pad 7 can effectively reduce the direct contact between the air-floating slider 11 and the end of the first buffer 15 during movement or positioning, and effectively reduce the impact and vibration generated when the air-floating slider 11 contacts the first buffer 15 when it moves quickly, which can effectively reduce the problem of damage to the air-floating slider 11 caused by impact, and effectively improve the stability of the air-floating slider 11 during operation.

[0030] The smaller the air film, the better the straightness, the slider will not have horizontal displacement, and the load-bearing capacity will be greater.

[0031] During operation, the positioning plate 12 is slid to the specified position in the middle of the guide rail body 1, and then the two groups of second exhaust pipes 31 on both sides of the positioning plate 12 are screwed to make the rubber pad 14 fit with the side wall of the guide rail body 1, and the positioning plate 12 is fixed by bolts 13 to control the injection and discharge of gas. When the gas layer is thick enough, the gas buoyancy supports the air-floating slider 11 and makes it suspend on the guide rail body 1. When the air-floating slider 11 approaches the end of the first buffer 15, the first buffer 15 absorbs the impact of the air-floating slider 11 when it slides, and the end of the air intake pipe 21 is connected to one end of the air pump, so that the air flow enters the hollow groove 2 through the air intake pipe 21, and the air flow enters the first exhaust pipe 22 and is discharged from the end. When the air-floating slider 11 approaches, the air flow blows to the surface of the air-floating slider 11. When the air-floating slider 11 approaches the end of the hollow groove 2, the side wall first fits with the end of the second exhaust pipe 31. When the air-floating slider 11 continues to move, the second exhaust pipe 31 slides inside the first exhaust pipe 22, and the second exhaust pipe 31 bounces during the movement. The spring 3 is elastically contracted by the pressure of the second exhaust pipe 31. At this time, the first exhaust hole 32 overlaps the second exhaust hole 33, and the air flow is discharged into the guide tube 34 through the first exhaust hole 32 and the second exhaust hole 33. The air flow is discharged from the end of the guide tube 34. When the positioning plate 12 adjusts its position in the middle of the guide rail body 1 and moves, the middle of the pulley 41 fits with the top of the guide rail body 1, so that when the positioning plate 12 moves, the pulley 41 rotates inside the groove 4 with the positioning plate 12, stretching the telescopic rod 5 and adjusting the height position of the second buffer 51. When the air-floating slider 11 contacts the end of the first buffer 15, the end of the second buffer 51 contacts the side of the device on the air-floating slider 11 at the same time. When the positioning plate 12 slides in the middle of the guide rail body 1, the sponge block 6 slides simultaneously with the positioning plate 12, and the inside of the slide groove 10 is cleaned by sliding the sponge block 6. When the air-floating slider 11 approaches the end of the first buffer 15, it contacts the surface of the air-floating slider 11 through the elastic pad 7.
