Description

Technical Field

[0001] This utility model relates to the field of guide rail technology, and more specifically, to a high-rigidity compact linear guide rail. Background Technology

[0002] As a core transmission component in industrial automation equipment, precision machine tools, medical devices, and electronic manufacturing equipment, linear guides directly determine the operating accuracy, load capacity, and service life of the equipment. With the increasing demands of modern industry for miniaturization, high precision, and long service life of equipment, traditional linear guides have gradually revealed various technical defects and are unable to meet the current industry development requirements.

[0003] In terms of structural compactness, the drive mechanism, lubrication mechanism and guide rail body of traditional linear guides are mostly designed independently. Each mechanism requires additional installation space and connecting parts, resulting in the entire guide rail system occupying a large amount of internal space. As automated equipment develops towards miniaturization and integration, this decentralized structural design greatly limits the space utilization of the equipment, making it difficult to adapt to the installation requirements of small precision equipment and increasing the complexity of the overall equipment design.

[0004] In terms of lubrication systems, traditional linear guides mostly use periodic manual lubrication. This method not only requires a lot of manpower, but also has problems such as inaccurate lubrication timing and difficulty in controlling the amount of lubrication: if lubrication is not timely, the frictional resistance between the slider and the high-rigidity guide rail will increase significantly, accelerating component wear; if lubrication is excessive, it will cause waste of lubricating oil, and excess lubricating oil may contaminate the internal environment of the equipment or the workpiece, affecting product quality.

[0005] Therefore, a high-rigidity, compact linear guide is proposed to address the above problems. Utility Model Content

[0006] 1. Technical problems to be solved

[0007] In view of the problems existing in the prior art, the purpose of this utility model is to provide a high-rigidity and compact linear guide rail, which can achieve a compact structure and smooth sliding function.

[0008] 2. Technical Solution

[0009] To solve the above problems, the present invention adopts the following technical solution.

[0010] A high-rigidity, compact linear guide rail includes a belt frame one, a motor fixedly connected to one side of the belt frame one, a drive wheel fixedly connected to the output end of the motor via a coupling, a drive belt meshing with the outer surface of the drive wheel, and a belt frame two meshing with the inner surface of the drive belt. A connecting rod is fixedly connected to the adjacent ends of the belt frame one and belt frame two. A guide rail structure is fixedly connected to the upper end of the connecting rod via bolts. A slider is slidably connected to the outside of the guide rail structure, and the slider is fixedly installed outside the drive belt. The guide rail structure includes a high-rigidity slide rail, with multiple mounting holes and multiple connecting holes at its upper end. Lubrication components are fixedly connected inside each of the multiple connecting holes. The lubrication components are directly integrated with the high-rigidity slide rail, eliminating the need for additional connecting parts, further reducing the overall volume of the guide rail system and improving structural compactness.

[0011] Furthermore, the lubrication assembly includes an oil tank, an electric push rod fixedly connected to the lower end of the oil tank, a piston fixedly connected to the output end of the electric push rod, the outer surface of the piston slidingly connected to the inner wall of the oil tank, an oil injection pipe fixedly connected and connected to the inner surface of the oil tank, a plug threadedly connected to the inner surface of the oil injection pipe, a photosensitive sensor installed at the upper end of the oil tank, and two output components fixedly connected and connected to the inner surface of the oil tank. The two output components are symmetrically distributed and can evenly deliver lubricating oil to different areas of the high-rigidity slide rail, ensuring comprehensive lubrication coverage.

[0012] Furthermore, the output component includes a three-way connector, the inner surface of which is fixedly connected to and connected to a one-way component, and the inner surface of which is fixedly connected to and connected to two oil outlet pipes. The outer surfaces of the two oil outlet pipes are fixedly connected to oil-absorbing strips. The oil-absorbing strips are made of porous wool felt material, which has excellent oil absorption and penetration properties, and is wear-resistant and not easy to fall off. They can absorb the lubricating oil delivered by the oil outlet pipes and then slowly and evenly penetrate to the surface of the high-rigidity slide rail through their porous structure to form a stable oil film, thus avoiding direct dripping of lubricating oil and causing waste or pollution.

[0013] Furthermore, the unidirectional component includes a connecting pipe, a flow pipe is fixedly connected to the inner surface of the connecting pipe, a flow plate one is fixedly connected to the inner surface of the flow pipe, a slide rod is slidably connected to the inner surface of the flow plate one, a sealing plate is fixedly connected to one side of the slide rod, a flow plate two is fixedly connected to the other side of the slide rod, and a spring is fixedly connected to the ends of the flow plate two and the flow plate one that are close to each other.

[0014] Furthermore, the connecting pipe is fixedly installed on the inner surface of the tee joint, the connecting pipe is fixedly installed on the inner surface of the oil drum, and the oil drum is fixedly installed on the inner wall of the connecting hole.

[0015] Furthermore, multiple oil-absorbing strips are respectively embedded on the upper and both sides of the high-rigidity slide rail, which is fixedly installed on the upper end of the connecting rod by bolts, and the outer surface of the high-rigidity slide rail is slidably connected to the inner surface of the slider.

[0016] 3. Beneficial Effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] (1) By setting up a lubrication system, this solution can significantly improve the stability of linear guide rail operation. The use of photosensitive sensors can achieve quantitative lubrication, which avoids the manpower consumption of manual lubrication and prevents waste and pollution caused by excessive lubrication. At the same time, it ensures that the lubricating oil can penetrate evenly to the contact surface of the high rigidity slide rail and the slider to form a stable oil film, reduce frictional resistance, effectively extend the service life of the slider and the high rigidity slide rail, improve the stability and reliability of the guide rail system operation, and reduce the failure rate of the equipment.

[0019] (2) This solution significantly reduces the overall system volume and enhances application flexibility through the integrated design of the guide rail structure and lubrication components. The lubrication components are directly installed inside the connection holes of the high-rigidity guide rail, without requiring additional equipment space. The layout is compact and the overall structure is simple, effectively improving the utilization rate of the internal space of the equipment. It can adapt to the installation needs of miniaturized and integrated modern industrial equipment and solves the problem of large space occupation caused by the dispersed structure of traditional guide rails.

[0030] Example 1:

[0031] Please see Figure 1 - Figure 5A high-rigidity, compact linear guide rail includes a belt frame 1. A motor 2 is fixedly connected to one side of the belt frame 1. The output end of the motor 2 is fixedly connected to a drive wheel via a coupling. A drive belt 3 is meshed with the outer surface of the drive wheel. A belt frame 6 is meshed with the inner surface of the drive belt 3. A connecting rod 4 is fixedly connected to the close ends of the belt frame 1 and the belt frame 6. A guide rail structure 5 is fixedly connected to the upper end of the connecting rod 4 via bolts. A slider 7 is slidably connected to the outside of the guide rail structure 5. The slider 7 is fixedly installed outside the drive belt 3. The guide rail structure 5 includes a high-rigidity slide rail 51. The high-rigidity slide rail 51 is fixedly installed to the upper end of the connecting rod 4 via bolts. The outer surface of the high-rigidity slide rail 51 is slidably connected to the inner surface of the slider 7. Multiple mounting holes 52 and multiple connecting holes 53 are opened at the upper end of the high-rigidity slide rail 51. Lubrication components 8 are fixedly connected inside each of the multiple connecting holes 53.

[0032] The high-rigidity slide rail 51 is made of GCr15 bearing steel and undergoes overall quenching and low-temperature tempering treatment. Its surface hardness can reach HRC60-62, which has extremely high rigidity and wear resistance. It can provide a sliding track for the slider 7, bear the weight of the slider 7 and the load, ensure that the slider 7 moves smoothly along a straight line, and avoid the transmission accuracy being affected by the deformation of the high-rigidity slide rail 51.

[0033] Mounting hole 52 is opened at the upper end of high rigidity slide rail 51. The inner wall of the hole is chamfered and the material is the same as that of high rigidity slide rail 51. This makes it easy to fix the entire guide rail system with bolts to ensure the installation stability of the guide rail system in the equipment, and also facilitates disassembly and maintenance in the future.

[0034] The connecting hole 53 is also opened on the upper end of the high-rigidity slide rail 51. The hole diameter matches the outer diameter of the oil tank 81. The inner wall of the hole is smooth and the material is the same as that of the high-rigidity slide rail 51. It can provide an installation position for the lubrication component 8 and fix the oil tank 81 on the high-rigidity slide rail 51, realizing the integrated design of the lubrication component 8 and the guide rail, reducing space occupation.

[0035] This solution starts the motor 2, which drives the drive wheel to rotate clockwise or counterclockwise according to the displacement direction requirement. At this time, the drive belt 3 will start to move horizontally under the friction of the drive wheel. At the same time, the inner surface of the drive belt 3 meshes with the belt frame 6. The belt frame 1 and the belt frame 6 are fixedly connected by the connecting rod 4 to form a stable support frame, ensuring that the drive belt 3 always remains taut during the movement and does not deviate or slip. The slider 7 can slide precisely in a straight line along the high-rigidity slide rail 51 under the drive of the drive belt 3. The load connected to the slider 7 will then complete the linear displacement. When the slider 7 slides along the high-rigidity slide rail 51, when it passes the lubrication component 8, the lubrication component 8 will seep out lubricating oil to lubricate the contact surface between the slider 7 and the high-rigidity slide rail 51, so as to ensure the smooth sliding of the slider 7.

[0036] Please see Figure 2 - Figure 5 The lubrication assembly 8 includes an oil tank 81, which is fixedly installed on the inner wall of the connection hole 53. An electric push rod 82 is fixedly connected to the lower end of the oil tank 81. A piston 83 is fixedly connected to the output end of the electric push rod 82. The outer surface of the piston 83 is slidably connected to the inner wall of the oil tank 81. An oil injection pipe 84 is fixedly connected to and communicates with the inner surface of the oil tank 81. A plug 85 is threadedly connected to the inner surface of the oil injection pipe 84. A photosensitive sensor 86 is provided at the upper end of the oil tank 81. Two output assemblies 9 are fixedly connected to and communicate with the inner surface of the oil tank 81.

[0037] The electric push rod 82 uses a DC servo motor inside, which has high control precision and can push the piston 83 to move inside the oil tank 81, squeeze the lubricating oil, and control the amount and timing of the lubricating oil discharge.

[0038] Piston 83 is made of oil-resistant polyurethane material with a smooth surface and a very small gap with the inner wall of oil tank 81, which has excellent sealing performance. It can squeeze the lubricating oil in oil tank 81 under the drive of electric push rod 82, generate pressure to make the lubricating oil flow to output component 9, and at the same time prevent the lubricating oil from leaking from the gap between piston 83 and the inner wall of oil tank 81.

[0039] The housing of the photosensitive sensor 86 is made of ABS plastic. It integrates a photoresistor, signal processing circuit and wire interface, and has good anti-interference performance. It can control the start and stop of the electric push rod 82 by sensing the light intensity.

[0040] The output component 9 includes a three-way connector 91, a one-way component 92 is fixedly connected and communicated to the inner surface of the three-way connector 91, two oil outlet pipes 93 are fixedly connected and communicated to the inner surface of the three-way connector 91, and oil suction strips 94 are fixedly connected to the outer surfaces of the two oil outlet pipes 93. Multiple oil suction strips 94 are respectively embedded on the upper side and both sides of the high rigidity slide rail 51.

[0041] The one-way component 92 includes a connecting pipe 921, which is fixedly installed on the inner surface of the tee connector 91 and the inner surface of the oil drum 81. A flow pipe 922 is fixedly connected to the inner surface of the connecting pipe 921. A flow plate 923 is fixedly connected to the inner surface of the flow pipe 922. A slide rod 924 is slidably connected to the inner surface of the flow plate 923. A sealing plate 925 is fixedly connected to one side of the slide rod 924, and a flow plate 926 is fixedly connected to the other side of the slide rod 924. A spring 927 is fixedly connected to the ends of the flow plate 926 and the flow plate 923 that are close to each other.

[0042] The sealing plate 925 is made of oil-resistant nitrile rubber with a smooth surface. It fits tightly against one side of the flow pipe 922 and can seal one end of the flow pipe 922 under the elastic force of the spring 927 to prevent lubricating oil from flowing back from the tee joint 91 to the oil tank 81, ensuring the one-way flow of the lubrication system. At the same time, it can also prevent lubricating oil from flowing from the oil tank 81 to the tee joint 91 when the electric push rod 82 stops working.

[0043] The oil-absorbing strip 94 is made of porous wool felt, which has excellent oil absorption and penetration properties. It is also wear-resistant and not easy to fall off. It can absorb the lubricating oil delivered by the oil pipe 93 and slowly and evenly penetrate the lubricating oil to the contact surface of the high-rigidity slide rail 51 and the slider 7 through its own porous structure, forming a stable oil film and reducing friction and wear.

[0044] This solution uses a photosensitive sensor 86 to detect light to release lubricating oil. Whenever the slider 7 slides above a lubrication component 8, it blocks the connection hole 53 at its installation position. At this time, the photosensitive sensor 86 detects the disappearance of the light source and sends an extension command to the electric push rod 82. The push rod of the electric push rod 82 extends and pushes the piston 83 to slide upward along the inner wall of the oil tank 81, squeezing the lubricating oil stored in the oil tank 81, so that the lubricating oil generates a certain pressure and flows to the one-way component 92 connected to the top of the oil tank 81.

[0045] The lubricating oil first enters the connecting pipe 921 of the one-way component 92, then flows into the interior of the flow pipe 922 through the second flow plate 926, and after passing through the first flow plate 923, it pushes the sealing plate 925 away from the port of the flow pipe 922, so that the lubricating oil can smoothly enter the tee connector 91 from the connecting pipe 921. At this time, the spring 927 is in a compressed state.

[0046] The three-way connector 91 evenly distributes the lubricating oil to two oil outlet pipes 93. The oil outlet pipes 93 deliver the lubricating oil to the oil suction strips 94 embedded on the upper and both sides of the high-rigidity slide rail 51. After the oil suction strips 94 absorb the lubricating oil through their porous structure, they slowly and evenly penetrate the lubricating oil to the contact surface between the high-rigidity slide rail 51 and the slider 7, forming a thin oil film between them. This significantly reduces the sliding friction coefficient, reduces component wear, and improves the smoothness of the slider 7's sliding.

[0047] When the slider 7 passes the lubrication assembly 8, the connection hole 53 is not blocked, the photosensitive sensor 86 senses the light source again, causing the electric push rod 82 to stop working and maintain its extension. The pressure in the oil tank 81 decreases accordingly, the spring 927 restores its elastic deformation, pushes the second flow plate 926 to move away from the first flow plate 923, and drives the sealing plate 925 to re-seal the port of the flow pipe 922 through the slide rod 924, preventing the lubricating oil in the tee joint 91 and the oil outlet pipe 93 from flowing back into the oil tank 81.

[0048] Since multiple connecting holes 53 are evenly distributed on the high-rigidity slide rail 51, the slider 7 will continuously pass through each lubrication component 8 during the sliding process. Each lubrication component 8 will automatically release oil after being blocked by the slider 7, and stop releasing oil after the slider 7 slides away, so that the slider 7 can be replenished with lubricating oil at any time during the whole process, making the sliding smoother.

[0049] It should be noted that the motor 2, photosensitive sensor 86, and electric push rod 82 in this utility model are powered by a power supply and controlled by a controller.

[0050] It should be noted that the specific installation methods, circuit connection methods, and control methods of the motor 2, photosensitive sensor 86, and electric push rod 82 in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0051] Working principle:

[0052] When using the linear guide, start the motor 2. The output end of the motor 2 can drive the drive wheel to rotate clockwise or counterclockwise according to the displacement direction requirements through the coupling. At this time, the drive belt 3 starts to move in the horizontal direction under the friction of the drive wheel. At the same time, the inner surface of the drive belt 3 meshes with the belt frame 6. The belt frame 1 and the belt frame 6 are fixedly connected by the connecting rod 4 to form a stable support frame, ensuring that the drive belt 3 always remains taut during the movement and does not deviate or slip.

[0053] When the drive belt 3 moves, the slider 7 moves synchronously. The slider 7 is in sliding engagement with the high-rigidity slide rail 51 of the guide rail structure 5. The high-rigidity slide rail 51 is firmly fixed to the upper end of the connecting rod 4 by bolts. Therefore, the slider 7 can slide precisely in a straight line along the high-rigidity slide rail 51 under the drive of the drive belt 3, and the load connected to the slider 7 will complete the linear displacement accordingly. According to actual needs, the speed of the motor 2 can be changed by adjusting the input current of the motor 2, thereby adjusting the rotation speed of the drive wheel, and finally achieving precise control of the slider 7's moving speed to meet the displacement speed requirements of different equipment.

[0054] During the operation of slider 7, lubrication component 8 will automatically perform lubrication work: whenever slider 7 slides above a lubrication component 8, it will block the connection hole 53 of its installation position. At this time, photosensitive sensor 86 senses the disappearance of the light source and sends an extension command to electric push rod 82. The push rod of electric push rod 82 extends and pushes piston 83 to slide upward along the inner wall of oil tank 81, squeezing the lubricating oil stored in oil tank 81, so that the lubricating oil generates a certain pressure and flows to the one-way component 92 connected to the top of oil tank 81.

[0055] The lubricating oil first enters the connecting pipe 921 of the one-way component 92, then flows into the interior of the flow pipe 922 through the second flow plate 926, and after passing through the first flow plate 923, it pushes the sealing plate 925 away from the port of the flow pipe 922, so that the lubricating oil can smoothly enter the tee connector 91 from the connecting pipe 921. At this time, the spring 927 is in a compressed state.

[0056] The three-way connector 91 evenly distributes the lubricating oil to two oil outlet pipes 93. The oil outlet pipes 93 deliver the lubricating oil to the oil suction strips 94 embedded on the upper and both sides of the high-rigidity slide rail 51. After the oil suction strips 94 absorb the lubricating oil through their porous structure, they slowly and evenly penetrate the lubricating oil to the contact surface between the high-rigidity slide rail 51 and the slider 7, forming a thin oil film between them. This significantly reduces the sliding friction coefficient, reduces component wear, and improves the smoothness of the slider 7's sliding.

[0057] When the slider 7 passes the lubrication assembly 8, the connection hole 53 will not be blocked, the photosensitive sensor 86 will sense the light source again, causing the electric push rod 82 to stop working and maintain its extension. The pressure in the oil tank 81 will decrease accordingly, the spring 927 will restore its elastic deformation, push the second flow plate 926 to move away from the first flow plate 923, and drive the sealing plate 925 to re-seal the port of the flow pipe 922 through the slide rod 924, preventing the lubricating oil in the tee joint 91 and the oil outlet pipe 93 from flowing back into the oil tank 81. Since multiple connecting holes 53 are evenly distributed on the high-rigidity slide rail 51, the slider 7 will continuously pass through each lubrication component 8 during the sliding process. Each lubrication component 8 will automatically release oil after being blocked by the slider 7, and stop releasing oil after the slider 7 slides away. This allows the slider 7 to be replenished with lubricating oil at any time during the entire process, making the sliding smoother. During use, the plug 85 can be unscrewed periodically, and an appropriate amount of lubricating oil can be added to the oil tank 81 through the oil injection pipe 84. After adding, the plug 85 should be tightened again.

[0058] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
