Description

Technical Field

[0001] This utility model relates to the field of guide rail device technology, and in particular to an air-floating platform guide rail. Background Technology

[0002] An air-bearing platform is a technology platform that uses gas (usually compressed air or vacuum) to form an extremely thin air film between moving parts and the support surface, thereby achieving contactless, low-friction, and high-precision motion. Because marble has good rigidity and stability, it can provide high-precision guidance and support for the air-bearing platform. The rectangular air-bearing guide rail of the air-bearing platform is made of a whole piece of marble. At the same time, marble has high hardness and good wear resistance, which can maintain the accuracy of the guide rail for a long time. In addition, its internal structure is stable and does not easily generate internal stress. Therefore, it is not easy to deform during use and can maintain high-precision performance for a long time.

[0003] In practical use, the existing rectangular marble air-bearing guide rails cannot be spliced ​​with external fastening structures when used with U-shaped air-bearing sliders. Otherwise, it would affect the movement of the air-bearing sliders, resulting in the inability to adjust the length of the rectangular marble air-bearing guide rails when used with U-shaped air-bearing sliders. If the two guide rails are fixed by gluing, they cannot be quickly disassembled, which limits the use of the air-bearing platform. Therefore, a new air-bearing platform guide rail is proposed to solve the above problems. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-2 This utility model provides an embodiment of an air-floating platform guide rail, including a marble guide rail body 1. A splicing groove 2 is provided on the left side surface of the marble guide rail body 1, and a screw 3 is provided inside the splicing groove 2. A limiting cavity 4 is provided inside the marble guide rail body 1, and a limiting block 5 is slidably connected inside the limiting cavity 4. The limiting block 5 can move linearly in the left and right directions inside the limiting cavity 4. At the same time, the marble material used for the marble guide rail body 1 has fine crystalline particles, a dense structure, and a small coefficient of linear expansion. It is less affected by temperature changes and can maintain high precision over a wide temperature range, which can reduce the influence of temperature on the movement of the limiting block 5. The right end of the screw 3 passes through the marble guide rail body 1 and is fixedly connected to the left side surface of the limiting block 5. When the screw 3 moves, it can drive the limiting block 5 to move synchronously.

[0031] Reference Figures 2-4A circular plate 6 is rotatably connected to the right side surface of the marble guide rail body 1. A circular hole 7 is opened on the outer wall surface of the circular plate 6. There are several circular holes 7, which are arranged in a ring array on the outer wall surface of the circular plate 6. The operator can insert a straight rod into the circular hole 7 and then rotate the straight rod to drive the circular plate 6 to rotate. A threaded cylinder 8 is fixedly connected to the right side surface of the circular plate 6. When the circular plate 6 rotates, it can drive the threaded cylinder 8 to rotate synchronously. The size and position of the screw 3 are adapted to the threaded cylinder 8. A tension spring 9 is fixedly connected to the right inner wall surface of the splicing groove 2.

[0032] A connecting unit 10 is provided on the left side of the tension spring 9. The connecting unit 10 includes a T-shaped block 101, which is fixedly connected to the left end of the tension spring 9. A fixing block 102 is fixedly connected to the right side surface of the marble guide rail body 1. A T-shaped groove 103 is provided on the upper surface of the fixing block 102. The right end of the T-shaped groove 103 passes through the fixing block 102. The size of the T-shaped groove 103 is adapted to the size of the T-shaped block 101. The T-shaped block 101 can be inserted into the interior of the T-shaped groove 103 and maintain the connection with the tension spring 9. When the two marble guide rail bodies 1 are spliced ​​and slid together, when the T-shaped block 101 is inserted into the interior of the T-shaped groove 103, the tension spring 9 is always in a stretched state, thereby generating elastic potential energy, which can pull the marble guide rail bodies 1 on both sides, so that the marble guide rail bodies 1 on both sides come closer to each other.

[0033] When splicing multiple marble guide rail bodies 1, the left side surface of the leftmost marble guide rail body 1 does not need to have a splicing groove 2 or other structures. Similarly, the right end of the rightmost marble guide rail body 1 does not need to have a circular plate 6 or other structures, so as to avoid affecting the installation of the spliced ​​marble guide rail body 1 group.

[0034] Reference Figures 2-3 A guide rod 11 is fixedly connected to the right side surface of the marble guide rail body 1, and a guide hole 12 is opened on the left side surface of the marble guide rail body 1. The size and position of the guide rod 11 are adapted to the guide hole 12. When splicing two marble guide rail bodies 1, the guide rod 11 can be inserted into the guide hole 12 to guide and limit the mutual movement between the two marble guide rail bodies 1, thereby further improving the splicing accuracy.

[0035] Working principle: When splicing two marble guide rail bodies 1, both marble guide rail bodies 1 can be placed on a horizontal surface first, and then initially aligned. Next, push the two marble guide rail bodies 1 closer together, so that the guide rod 11 is inserted into the guide hole 12 to guide and limit the splicing, and the screw 3 and threaded cylinder 8 are quickly aligned. When the screw 3 and threaded cylinder 8 come into contact, a straight rod can be inserted into the round hole 7 to continuously rotate the round plate 6, so that the screw 3 rotates into the threaded cylinder 8. When it starts to rotate, the screw 3 will drive the limiting block 5 to move to the left. After the screw 3 completely fills the inside of the threaded cylinder 8, the limiting block 5 will move to the left end of the limiting cavity 4. At this time, through the connection and cooperation of the round plate 6, threaded cylinder 8, screw 3 and limiting block 5, the splicing point between the two marble guide rail bodies 1 can be limited, improving the connection strength. At the same time, it can prevent the two marble guide rail bodies 1 from separating during installation, disassembly or use.

[0036] Then, the T-shaped block 101 is pulled out of the splicing groove 2 by the hook and inserted into the T-shaped groove 103. At this time, the tension spring 9 is stretched to generate elastic potential energy. Finally, it pushes the two marble guide rail bodies 1 to come closer together to complete the splicing and extend the service length of the guide rail. When the two marble guide rail bodies 1 are put together, the tension spring 9 is still in a stretched state to generate elastic potential energy, which can pull the marble guide rail bodies 1 on both sides, making the fit between the two marble guide rail bodies 1 tighter and avoiding cracks that would affect the movement of the air-floating slider. The structure is simple and easy to operate. At the same time, the guide rod 11 can distribute the pressure borne by the whole composed of the circular plate 6, threaded cylinder 8, screw 3 and limiting block 5 when the guide rail is used in the air, which can extend the service life of the structure.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
