Description

Technical Field

[0001] This utility model relates to the field of guide rail technology, and in particular to silent aluminum profile guide rails. Background Technology

[0002] In current industrial production and various mechanical equipment applications, guide rails, as a key guiding component, are widely used in machine tools, automated production lines, office furniture drawers, and many other fields. Their performance directly affects the overall operational efficiency of the equipment. Traditional aluminum profile guide rails have inherent defects in the mating structure of the slider and groove. For example, the aluminum profile silent guide rail shown in patent publication number CN222254706U, while having some rationality in its structural design, still generates considerable noise and friction during actual use due to the sliding contact between the slider and groove. In high-precision machining equipment, this noise not only interferes with the working environment but may also affect the machining accuracy; in furniture drawer applications, noise reduces the user experience. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a silent aluminum profile guide rail. The specific technical solution is as follows:

[0004] The silent aluminum profile guide rail includes a fixed slide rail and a movable slide rail. The movable slide rail is fitted onto the surface of the fixed slide rail. The outer side of the fixed slide rail has several grooves, and the inner wall of the movable slide rail has several slide bars that fit the grooves. A sound-absorbing layer made of high-polymer elastic material is fixedly connected to the surface of the groove. The groove has multiple through slots along its circumference. One end of each through slot passes through the sound-absorbing layer, and the other end of each through slot has an adapter slot. A roller is rotatably installed in the through slot. One end of the roller contacts the slide bar, and the other end of the roller is located in the adapter slot.

[0005] Preferably, the slider has an inner groove in a vacuum state, and multiple partitions are fixedly connected inside the inner groove. The partitions divide the inner side into multiple independent spaces to achieve a silent effect.

[0006] Preferably, the cross-sectional area of ​​the slider is semi-circular, and the sound-silencing layer is arc-shaped and adapted to the slider.

[0007] The polymeric elastic material is either polyurethane elastomer or silicone rubber.

[0008] The beneficial effects of this utility model are:

[0009] 1. By setting a sound-absorbing layer made of polyurethane elastomer or silicone rubber on the surface of the slide rail, the vibration and impact force generated by the sliding of the slide bar can be effectively absorbed, reducing noise generation. At the same time, the vacuum groove and baffle structure inside the slide bar prevents sound transmission and resonance, and the roller converts sliding friction into rolling friction, which also reduces friction noise. This achieves a comprehensive silent effect, providing a quiet operation guarantee for noise-sensitive working environments and equipment.

[0010] 2. The rolling design of the rollers within the through groove greatly reduces the friction between the slide bar and the slide groove, reduces heat generated by friction and component wear, extends the service life of the guide rail, reduces equipment maintenance costs and replacement frequency, and improves the overall stability and reliability of the equipment operation.

[0011] 3. Through the close cooperation between the fixed and movable slide rails, the adaptation between the slide bar and the sound-absorbing layer, and the stable rotation of the rollers, the smoothness and accuracy of the movable slide rail's movement relative to the fixed slide rail are ensured. This is beneficial to improving the operating accuracy and work efficiency of the equipment and is of great significance in application scenarios such as high-precision processing equipment.

[0012] 4. The semi-circular design of the slider and the tight fit of the arc-shaped sound-absorbing layer make the contact more uniform and reasonable. This not only helps to reduce noise and wear, but also enhances the stability of the overall guide rail structure, prevents component displacement or deformation caused by uneven force, and ensures long-term stable operation of the equipment.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Example

[0019] Please refer to Figures 1-3This silent aluminum profile guide rail mainly consists of a fixed slide rail 1 and a movable slide rail 2. The movable slide rail 2 is tightly fitted onto the surface of the fixed slide rail 1 to ensure relative stability during movement. Several grooves 6 are evenly distributed along the length of the outer side of the fixed slide rail 1. The size and shape of these grooves 6 are precisely designed to ensure accurate fit with the slide strips 3 on the inner wall of the movable slide rail 2.

[0020] This application features a sound-absorbing layer 5 securely fixed to the surface of the slide rail 6. This sound-absorbing layer 5 is made of a high-performance polymer elastic material, specifically polyurethane elastomer or silicone rubber. Polyurethane elastomer possesses excellent elastic recovery, wear resistance, and tear resistance, maintaining good cushioning performance during long-term use; silicone rubber exhibits excellent high-temperature resistance, aging resistance, and chemical stability, adapting to various working environments. The thickness of the sound-absorbing layer 5 has been carefully calculated and experimentally verified to effectively absorb the vibration and impact generated during the sliding of the slide bar 3, without compromising the overall structural strength and assembly accuracy of the guide rail due to excessive thickness.

[0021] Multiple through slots 50 are evenly arranged along the circumference of the slide groove 6. One end of each through slot 50 is connected to the surface of the sound-absorbing layer 5, and the other end extends to the adapter slot 100. Inside each through slot 50, a freely rotating roller 4 is cleverly installed. One end of the roller 4 maintains a tight and smooth contact with the slide bar 3. When the slide bar 3 moves within the slide groove 6, its movement smoothly drives the roller 4 to roll within the through slot 50. The other end of the roller 4 is precisely located in the adapter slot 100, which provides stable support and limit for the roller 4, ensuring that the roller 4 maintains the correct position and posture during rotation. This efficiently converts the sliding friction between the slide bar 3 and the slide groove 6 into rolling friction, greatly reducing friction, heat and wear caused by friction, and further reducing noise generation.

[0022] To further enhance the noise reduction effect, the slider 3 is designed with a vacuum-sealed inner groove 300. In a vacuum environment, sound propagation is greatly hindered, effectively reducing the outward transmission of noise generated by the slider 3 due to vibration. Multiple partitions 31 are reliably connected inside the inner groove 300 by welding or bonding, dividing the inner groove 300 into multiple independent spaces. Each independent space can independently suppress sound resonance and propagation, avoiding the amplification of overall structural noise caused by local vibration, thus further optimizing the noise reduction performance from the internal structure.

[0023] Furthermore, the cross-sectional area of ​​the slider 3 is semi-circular. This design ensures a more uniform contact area and a more reasonable distribution of contact pressure when the slider 3 is in contact with the curved sound-absorbing layer 5. During sliding, it can better adapt to different stress conditions, reducing noise and wear caused by localized stress concentration. It also improves the sealing performance between the slider 3 and the sound-absorbing layer 5, preventing dust and debris from entering the guide rail and maintaining the cleanliness and operational stability of the guide rail.

[0024] In the actual manufacturing process, high-strength aluminum alloy material is first selected, and the fixed slide rail 1 and the movable slide rail 2 are made through a precision extrusion molding process. For the fixed slide rail 1, when machining the slide groove 6, high-precision CNC machining equipment is used to ensure that the dimensional tolerance of the slide groove 6 is controlled within a very small range, and the surface roughness reaches the mirror level, so as to ensure that the slide bar 3 can slide smoothly and stably in it.

[0025] When installing the sound-absorbing layer 5, the polyurethane elastomer or silicone rubber material is first molded into a prefabricated part that perfectly matches the shape of the slide groove 6 according to a specific mold. Then, it is tightly bonded to the surface of the slide groove 6 using a special adhesive. During the bonding process, the amount of adhesive used and the uniformity of application are strictly controlled to ensure that there are no air bubbles or gaps between the sound-absorbing layer 5 and the slide groove 6, forming a strong integrated structure.

[0026] The through groove 50 is also machined using CNC machining technology to ensure that its diameter, depth, and axial accuracy meet design requirements. The roller 4 is made of high-precision stainless steel or engineering plastic and is installed within the through groove 50 using a precise assembly process. During installation, the axial clearance and radial runout of the roller 4 are rigorously tested and adjusted to ensure good contact between the roller 4 and the slide bar 3, allowing for flexible rotation.

[0027] When manufacturing the slider 3, a special vacuum casting process is first used to form an inner groove 300 with an internal vacuum state. Then, the pre-processed partition 31 is fixed to the inner groove 300 by welding or high-strength adhesive. When processing the semi-circular shape of the slider 3, precision machining equipment is used to ensure its surface roughness and dimensional accuracy, so that it can achieve a tight and stable fit with the arc-shaped sound-absorbing layer 5.

[0028] When the device drives the movable slide rail 2 to move linearly relative to the fixed slide rail 1, the slide bar 3 on the inner wall of the movable slide rail 2 moves within the groove 6 of the fixed slide rail 1. Because the slide bar 3 is in close contact with the roller 4, the movement of the slide bar 3 causes the roller 4 to roll quickly and smoothly within the through groove 50. In this process, the sliding friction between the slide bar 3 and the groove 6 is effectively converted into rolling friction of the roller 4, greatly reducing friction, heat generated by friction, and wear, thereby reducing noise.

[0029] Meanwhile, the sound-absorbing layer 5 utilizes the excellent properties of its high-polymer elastic material to efficiently absorb and buffer the vibration and impact generated by the slider 3 during sliding. When the slider 3 vibrates, the vibration energy is transferred to the sound-absorbing layer 5 through contact with it. The elastic structure of the sound-absorbing layer 5 can quickly disperse and dissipate this energy, avoiding the accumulation and transmission of vibration energy, and further reducing noise.

[0030] The vacuum groove 300 and partition 31 inside the slider 3 effectively prevent sound propagation and resonance from the inside. In a vacuum environment, sound cannot travel through the air, and the partition 31 divides the groove 300 into multiple independent spaces, avoiding the amplification of overall structural noise caused by local vibration. This ensures that the noise generated by the slider 3 itself is confined to the inside to the maximum extent and does not propagate outward, thus achieving an all-around silent effect.

[0031] In summary, this utility model, through its unique structural design and material selection, effectively solves the noise and friction problems of existing aluminum profile guide rails during the sliding process from multiple aspects, significantly improving the performance and service life of the guide rails, and providing an efficient, reliable, and silent guide rail solution for various mechanical equipment and furniture industries.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
