Description
Technical Field
[0001] This utility model relates to the field of air-bearing guide rail technology, specifically a silicon carbide ceramic triangular beam air-bearing guide rail. Background Technology
[0002] In the fields of precision manufacturing and high-end equipment, the requirements for the precision, stability, and reliability of moving parts are constantly increasing. With the development of technology, triangular beam air-bearing guides have emerged. These guides utilize gas as a lubricant to form an air film between the guide rail and the slider, achieving contactless motion, effectively reducing friction and wear, and improving motion precision and stability. Silicon carbide ceramics possess excellent properties such as ultra-high hardness, high strength, low coefficient of thermal expansion, and good thermal and chemical stability. Applying SiC ceramics to triangular beam air-bearing guides can fully leverage their material advantages, significantly improving the rigidity, precision retention, and resistance to environmental interference of the air-bearing guides, meeting the growing demand for precision moving parts in modern high-end equipment manufacturing. Therefore, silicon carbide ceramic triangular beam air-bearing guides have gradually become a research and application hotspot.
[0003] Existing silicon carbide ceramic triangular beam air-bearing guides are widely used, but the height of existing devices is usually not adjustable or requires manual adjustment, which is quite troublesome. Furthermore, the level adjustment of the air-bearing guide is not convenient enough, and if the air-bearing guide is tilted, the slider will be difficult to move. Therefore, to address the above problems, a silicon carbide ceramic triangular beam air-bearing guide is proposed. Utility Model Content
[0004] The purpose of this invention is to provide a silicon carbide ceramic triangular beam air-bearing guide rail to solve the problems mentioned in the background art, such as the cumbersome height adjustment and inconvenient level adjustment of the existing devices.

[0009] Preferably, a bubble level is fixedly connected to both the front and rear sides and the left and right ends of the fixed plate. A vertically arranged fixed ball rod is fixedly connected to one side of the bottom end of the fixed plate. A fixed ball seat is rotatably connected to the outer bottom of the fixed ball rod. A connecting plate is fixedly connected to the bottom end of the fixed plate on one side of the fixed ball rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. In this utility model, by setting an air inlet three-way valve, one-way valve, telescopic hose, conduit, lifting assembly, fixed cylinder, piston, limit block, lifting rod, exhaust valve and fixed plate, when the height of the device needs to be adjusted, the air pump is started, the outside air enters the inside of the fixed cylinder, the piston moves upward and drives the air float guide rail body to move upward until the air float guide rail body moves to the appropriate height. After the device is used, the exhaust valve is opened to discharge the air inside the fixed cylinder, and the air float guide rail body descends accordingly. The design of the lifting assembly and its connecting components makes the height adjustment of the air float guide rail body more convenient and improves work efficiency.
[0013] 2. In this utility model, the air-bearing guide rail body is leveled by using a bubble level, a fixed ball rod, a fixed ball seat, a connecting plate, a threaded ball rod, an adjusting ball seat, and a hand-tightening nut.

[0023] Please see Figure 1-5 This utility model provides a technical solution:
[0024] A silicon carbide ceramic triangular beam air-bearing guide rail includes an air-bearing guide rail body 1 and a slider 2 disposed at the top of the air-bearing guide rail body 1. One end of the air-bearing guide rail body 1 is fixedly connected to an air inlet three-way valve 3 communicating with the air-bearing guide rail body 1. One end of the air outlet of the air inlet three-way valve 3 is fixedly connected to a one-way valve 4 communicating with the air inlet three-way valve 3. The bottom end of the one-way valve 4 is fixedly connected to a telescopic hose 5 communicating with the one-way valve 4. The bottom end of the telescopic hose 5 is fixedly connected to a conduit 6 communicating with the telescopic hose 5. Multiple sets of lifting components 7 are installed on the outside of the conduit 6. The end of the conduit 6 away from the telescopic hose 5 is fixedly connected to an exhaust valve 8 communicating with the conduit 6. A fixing plate 9 is installed at the bottom end of the lifting components 7. The lifting components 7 include a fixing cylinder 71 fixedly connected to the top of the fixing plate 9. A piston 72 is disposed inside the fixing cylinder 71, tightly fitting against the inside of the fixing cylinder 71. A limit block 73 is fixedly connected to the bottom end of the piston 72, and a limit block 73 is fixedly connected to the top end of the piston 72. A vertically arranged lifting rod 74 passes through and is slidably connected to a fixed cylinder 71. The top end of the lifting rod 74 is fixedly connected to the bottom end of the air-bearing guide rail body 1. A conduit 6 is fixedly connected to the outside of the fixed cylinder 71 and passes through it. Through the provided air inlet three-way valve 3, one-way valve 4, telescopic hose 5, conduit 6, lifting assembly 7, fixed cylinder 71, piston 72, limit block 73, lifting rod 74, exhaust valve 8, and fixed plate 9, when the height of the device needs to be adjusted, the air pump is started, and outside air enters the inside of the fixed cylinder 71. The piston 72 moves upward, driving the air-bearing guide rail body 1 to move upward until the air-bearing guide rail body 1 reaches the appropriate height. After the device is used, the exhaust valve 8 is opened to discharge the air inside the fixed cylinder 71, and the air-bearing guide rail body 1 descends accordingly. The design of the lifting assembly 7 and its connecting components makes the height adjustment of the air-bearing guide rail body 1 more convenient and improves work efficiency.
[0025] Bubble levels 10 are fixedly connected to the front and rear sides and left and right ends of the fixed plate 9. A vertically set fixed ball rod 11 is fixedly connected to one side of the bottom end of the fixed plate 9. A fixed ball seat 12 is rotatably connected to the outer bottom of the fixed ball rod 11. A connecting plate 13 is fixedly connected to the bottom end of the fixed plate 9 on one side of the fixed ball rod 11. A vertically set threaded ball rod 14 that penetrates the connecting plate 13 is symmetrically set on the inner side of the connecting plate 13. An adjusting ball seat 15 is rotatably connected to the outer bottom of the threaded ball rod 14. A hand-tightening nut 16 is threadedly connected to the outer side of the threaded ball rod 14. The fixed ball seat 12 and the adjusting ball seat 15 are the same in shape and size. The hand-tightening nut 16 is set at the bottom of the connecting plate 13. By using the bubble level 10, fixed ball rod 11, fixed ball seat 12, connecting plate 13, threaded ball rod 14, adjusting ball seat 15 and hand-tightening nut 16, the air-bearing guide rail body 1 is leveled. By rotating the hand-tightening nut 16 under the connecting plate 13, the air-bearing guide rail body 1 begins to tilt forward and backward or left and right until the bubble level 10 located on the front and back sides and left and right ends of the fixed plate 9 is in a horizontal state, thus completing the leveling of the air-bearing guide rail body 1. This design makes the leveling of the air-bearing guide rail body 1 more convenient and ensures that the air-bearing guide rail body 1 can be used normally.
[0026] Workflow: Before use, power on the equipment and connect the external control device. Connect the air pump to the air inlet of the three-way valve 3. Adjust the three-way valve 3 to connect the air pump to the one-way valve 4. Then start the air pump. The air pump draws outside air into the inside of the fixed cylinder 71 through the one-way valve 4, the telescopic hose 5, and the conduit 6. The increased pressure inside the fixed cylinder 71 causes the piston 72 to move upward. The lifting rod 74 slides inside the fixed cylinder 71, driving the air-bearing guide rail body 1 upward until it reaches the appropriate height. The one-way valve 4 is designed to maintain the fixed position. The air pressure inside cylinder 71 maintains the height of the air-bearing guide rail body 1. Next, the air-bearing guide rail body 1 is leveled. The hand-tightening nut 16 below the connecting plate 13 is rotated to cause the air-bearing guide rail body 1 to tilt left and right. The fixed ball rod 11 rotates inside the fixed ball seat 12, and the threaded ball rod 14 rotates inside the adjusting ball seat 15, until the bubble level 10 located on both sides of the fixed plate 9 is horizontal. Next, the hand-tightening nut 16 on the outside of the single threaded ball rod 14 is rotated to cause the air-bearing guide rail body 1 to tilt back and forth. The fixed ball rod 11 rotates inside the fixed ball seat 12. Rotating inwards, the threaded ball rod 14 rotates inside the adjusting ball seat 15 until the bubble level 10 located at both ends of the fixed plate 9 is in a horizontal state, thus completing the leveling of the air-bearing guide rail body 1. This design makes the leveling of the air-bearing guide rail body 1 more convenient and ensures that the air-bearing guide rail body 1 can be used normally. Next, adjust the air inlet three-way valve 3 to connect the air pump with the air-bearing guide rail body 1, and then start the air pump. At this time, air enters the inside of the air-bearing guide rail body 1 and is discharged through multiple small holes on the air-bearing guide rail body 1, forming a gap between the air-bearing guide rail body 1 and the slider 2. Once the air film is formed, slider 2 can move normally. After the device is used, the air pump is turned off and the exhaust valve 8 is opened. The air inside the fixed cylinder 71 is discharged through the exhaust valve 8. The piston 72 moves downward until the bottom end of the limit block 73 contacts the bottom end of the inner side of the fixed cylinder 71. The air-floating guide rail body 1 can then be reset. The design of the limit block 73 allows the piston 72 to maintain a distance from the bottom end of the inner side of the fixed cylinder 71, thus not affecting the gas entering the inner side of the fixed cylinder 71. The design of the lifting component 7 and its connecting components makes the height adjustment of the air-floating guide rail body 1 more convenient and improves work efficiency.
