Description

Technical Field

[0001] This utility model relates to the field of linear guide technology, and in particular to a high-speed, low-noise linear guide. Background Technology

[0002] Linear guides, as core components for achieving linear reciprocating motion in mechanical equipment, are widely used in machine tool processing, electronic manufacturing equipment, automated production lines, and many other fields. As industrial production continues to advance towards higher speeds and greater precision, even more stringent challenges are being placed on the performance of linear guides.

[0003] There are many problems in the traditional design and application of linear guides that urgently need improvement.

[0004] The existing technology has the following shortcomings:

[0005] 1) On the one hand, when the linear guide is running at high speed, the friction between the guide and the slider and the collision of the rolling elements in the cycle process will generate a lot of noise. This noise not only interferes with the working environment and causes fatigue and discomfort to the operators, but may also affect the normal operation of the surrounding precision instruments.

[0006] 2) Under high-speed conditions, due to factors such as increased friction and uneven lubrication, the guide rail is prone to wear, which in turn affects its operating accuracy and service life. Taking machine tool processing as an example, after long-term high-speed operation, the wear of traditional linear guide rails will reduce the positioning accuracy of the tool during the processing, resulting in increased dimensional deviation of the machined parts and an increase in scrap rate. Utility Model Content

[0007] This invention provides a high-speed, low-noise linear guide rail that achieves automatic lubrication by utilizing the movement of the lower sliding frame, thereby reducing sliding friction, decreasing noise, and improving operational stability. Furthermore, its optimized structure, convenient installation, and small space occupation overcome the shortcomings of traditional guide rails and address the problems mentioned in the background section.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a high-speed, low-noise linear guide rail, including a working base, a sliding table fixedly connected to the top of the working base, an oil injection device slidably connected to the outer surface of the sliding table, the oil injection device including an oil storage tank, an oil injection nozzle fixedly connected to the top of the oil storage tank, an oil injection nozzle fixedly connected to the outer surface of the oil storage tank, and an oil delivery pipe fixedly connected to one end of the oil injection nozzle.

[0009] Preferably, the bottom of the oil pipeline is fixedly connected to an oil separator, the bottom of the oil separator is a rotating column, the outer wall of the rotating column is fixedly connected to a rotating shaft, and the outer wall of the rotating shaft is rotatably connected to a silent pulley.

[0010] Preferably, the outer wall of the silent pulley is provided with an oil outlet hole.

[0011] Preferably, the outer wall of the sliding platform is slidably fitted with a lower sliding frame.

[0012] Preferably, an oil injection system protection frame is fixedly connected to the top of the lower sliding frame.

[0013] Preferably, the outer surface of the lower sliding frame is fixedly connected to the outer surface of the oil storage tank.

[0014] Preferably, the outer wall of the silent pulley and the outer wall of the sliding table are rotated and fitted together.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, an external power drives the sliding component to move, causing the oil storage component to move synchronously. The lubricating oil is delivered through a pipeline and led by the distribution component to the rotating component. When the rotating component is running, the lubricating oil is evenly coated on the sliding surface to achieve lubrication of the sliding component. Through precise lubrication, friction between sliding components is greatly reduced, noise generation is reduced, and a quiet equipment operating environment is created. This solves the problem that the accuracy and lifespan of traditional guide rails are affected under high-speed conditions. The stable support structure combined with uniform lubrication ensures that the sliding components are subjected to balanced forces, reduces wear and running deviation, improves the running stability of the guide rail, and extends its service life. It changes the traditional situation of untimely lubrication and complex structure. It uses sliding power to automatically complete the lubrication delivery, simplifies the structure, and at the same time, the protective components ensure the stability of the lubrication system and ensure long-term efficient operation.

[0017] 2. In this utility model, the linear guide rail has wide applicability in practical applications. Its compact structural design makes it suitable not only for precision equipment with limited space, but also for scenarios with stringent space layout requirements such as automated production lines and industrial robotic arms. Thanks to its convenient installation and stable performance, it can be quickly integrated into existing systems, improving the overall operating efficiency and reliability of the equipment, and helping industrial production develop towards high speed, high precision, and low noise.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Please see attached Figure 1 -Appendix Figure 4 As shown, this utility model provides a technical solution: Figure 1As shown, the high-speed, low-noise linear guide structure of this embodiment includes a working base 1. A sliding platform 2 is fixedly connected to the top of the working base 1. An oil injection device 3 is slidably connected to the outer surface of the sliding platform 2. The oil injection device 3 includes an oil storage tank 301. An oil injection nozzle 302 is fixedly connected to the top of the oil storage tank 301 and to the outer surface of the oil storage tank 301. One end of the oil injection nozzle 302 is fixedly connected to an oil delivery pipe 303. The fixed connection of the sliding platform 2 to the top of the working base 1 provides a stable foundation support for the entire linear guide system. The working base 1 can stably support the sliding platform 2 and other components running on it, ensuring that the sliding platform 2 will not shift or shake during operation. This creates favorable conditions for the smooth sliding of the lower sliding frame 4 and the precise operation of the entire linear guide, which is beneficial to improving the stability and accuracy of the equipment operation. The oil injection device is slidably connected to the outer surface of the sliding platform 2. 3. This allows the oil injection device 3 to move synchronously on the sliding platform 2 as the lower sliding frame 4 moves. This connection method ensures that the oil injection device 3 lubricates the sliding platform 2 in real time. No matter where the lower sliding frame 4 is on the sliding platform 2, the timely supply of lubricating oil can be guaranteed, effectively reducing the friction between the sliding platform 2 and the lower sliding frame 4, reducing wear and noise, and extending the service life of the linear guide rail. The top of the oil storage tank 301 is fixedly connected to the oil injection nozzle 302, and the outer surface of the oil storage tank 301 is also fixedly connected to the oil injection nozzle 302. This design allows the lubricating oil in the oil storage tank 301 to be conveniently drawn out from multiple directions. The oil injection nozzle 302 on the top can be used to inject lubricating oil into the oil delivery pipe 303 to provide an oil source for the entire oil injection system; the oil injection nozzle 302 on the outer surface can replenish the oil storage tank 301 when needed, ensuring that there is always enough lubricating oil in the oil storage tank 301 to maintain the continuous operation of the oil injection system.

[0026] like Figure 1As shown, the bottom of the oil supply pipe 303 is fixedly connected to the oil distributor 304. The bottom of the oil distributor 304 has a rotating column 305, and the outer wall of the rotating column 305 is fixedly connected to a rotating shaft 306. A silent pulley 307 is rotatably connected to the outer wall of the rotating shaft 306. One end of the oil nozzle 302 is fixedly connected to the oil supply pipe 303, realizing the directional delivery of lubricating oil from the oil storage tank 301 to the oil distributor 304. The oil supply pipe 303 can stably and efficiently guide the lubricating oil to the oil distributor 304, ensuring the sealing of the lubricating oil delivery process, preventing lubricating oil leakage, and ensuring the normal operation of the entire oil injection system. The bottom of the oil supply pipe 303 is fixedly connected to the oil distributor 304, which can evenly distribute the lubricating oil delivered by the oil supply pipe 303 to each rotating column 305. This connection method ensures that the lubricating oil can evenly cover the sliding table surface 2. The different positions of the sliding frame 4 ensure that all parts are fully lubricated during the sliding process, further reducing the coefficient of friction, reducing local wear and noise differences caused by uneven lubrication, and improving the smoothness and consistency of the linear guide rail operation. The bottom of the oil connector 304 is connected to the rotating column 305. When the oil connector 304 distributes the lubricating oil, the rotating column 305 can rotate with the movement of the sliding frame 4, transmitting the lubricating oil to the rotating shaft 306 and the silent pulley 307. This connection method cleverly utilizes the moving power of the sliding frame 4 to realize the automatic delivery and application of lubricating oil without the need for an additional power device, simplifying the structure and improving energy utilization efficiency. The outer wall of the rotating column 305 is fixedly connected to the rotating shaft 306. The rotation of the rotating column 305 can drive the rotating shaft 306 to rotate synchronously, thereby driving the silent pulley 307 to rotate.

[0027] Please see attached Figure 1 -Appendix Figure 4 As shown, the outer wall of the silent pulley 307 is provided with an oil outlet hole 308. This connection method ensures the effective transmission of power, so that the silent pulley 307 can rotate and roll stably on the outer wall of the sliding table 2, ensuring that the lubricating oil can be evenly carried out from the oil outlet hole 308 and applied to the surface of the sliding table 2.

[0028] Please see attached Figure 1 -Appendix Figure 4 As shown, the lower sliding frame 4 is slidably attached to the outer wall of the sliding table 2, providing good lubrication conditions for the sliding of the lower sliding frame 4. The outer wall of the rotating shaft 306 is rotatably connected to a silent pulley 307, which allows the silent pulley 307 to rotate flexibly around the rotating shaft 306. The silent pulley 307 adopts a special design, which can reduce the friction and noise between itself and the rotating shaft 306 during rotation. At the same time, an oil outlet hole 308 is opened on its outer wall, which can evenly apply lubricating oil to the surface of the sliding table 2, reduce the friction and noise between the lower sliding frame 4 and the sliding table 2, and achieve high-speed and low-noise operation.

[0029] Please see attached Figure 1 -Appendix Figure 4 As shown, the top of the lower sliding frame 4 is fixedly connected to the oil injection system protection frame 41, and the lower sliding frame 4 is slidably attached to the outer wall of the sliding table 2. This sliding attachment connection realizes the basic function of the linear guide rail, that is, the lower sliding frame 4 can slide linearly on the sliding table 2. Through the lubrication of the sliding table 2 by the oil injection device 3, the frictional resistance between the two is greatly reduced, so that the lower sliding frame 4 can achieve high-speed and stable sliding, meeting the equipment's requirements for high-speed operation of the linear guide rail.

[0030] Please see attached Figure 1 -Appendix Figure 4 As shown, the outer surface of the lower sliding frame 4 is fixedly connected to the outer surface of the oil storage tank 301. The top of the lower sliding frame 4 is fixedly connected to the oil injection system protection frame 41. The oil injection system protection frame 41 can effectively protect the oil injection device 3. It can prevent external debris such as dust and debris from entering the oil injection device 3, avoid damage to the internal structure of the oil injection device 3, and ensure that the oil injection device 3 can stably and continuously provide lubrication for the linear guide rail, ensuring that the linear guide rail can operate stably at high speed and low noise for a long time. The outer surface of the lower sliding frame 4 is fixedly connected to the outer surface of the oil storage tank 301, so that the oil storage tank 301 can move with the movement of the lower sliding frame 4. This connection method ensures that the oil injection device 3 can always follow the position change of the lower sliding frame 4 and lubricate the contact area between the lower sliding frame 4 and the sliding table 2 in real time, ensuring that the linear guide rail can be fully lubricated and protected throughout the entire operation. The outer wall of the silent pulley 307 rotates and fits against the outer wall of the sliding table 2.

[0031] Please see attached Figure 1 -Appendix Figure 4 As shown, the outer wall of the silent pulley 307 and the outer wall of the sliding table 2 rotate in contact. During rotation, the silent pulley 307 can carry lubricating oil from the oil outlet 308 and evenly apply it to the surface of the sliding table 2. This rotating contact connection method realizes the automatic application of lubricating oil. At the same time, the low noise characteristics of the silent pulley 307 itself also help reduce the noise generated during the operation of the entire linear guide, providing a strong guarantee for achieving high-speed, low-noise operation.

[0032] Working principle: When the linear guide rail starts working, the external drive device such as the motor acts on the lower sliding frame 4, causing it to slide along the sliding table 2. Since the lower sliding frame 4 is fixedly connected to the oil storage tank 301, this sliding action will drive the entire oil injection device 3 to move synchronously. The oil storage tank 301 stores lubricating oil, which enters the oil delivery pipe 303 through the oil injection nozzle 302 fixedly connected to the top. The oil delivery pipe 303 guides the lubricating oil to the oil distributor 304, which evenly distributes the lubricating oil so that it can flow to the rotating column 305. The rotating column 305 rotates with the movement of the lower sliding frame 4, and the rotating shaft 306 fixedly connected to the outer wall of the rotating column 305 drives the silent pulley 307 to rotate together. The moving, silent pulley 307 rotates and rolls against the outer wall of the sliding table 2. Its outer wall has an oil outlet 308. During rotation, lubricating oil is carried out from the oil outlet 308 and evenly coated on the surface of the sliding table 2. Thus, when the lower sliding frame 4 slides, the lubrication between it and the sliding table 2 greatly reduces the coefficient of friction, thereby reducing noise generated by friction. This also facilitates high-speed operation. The oil injection system protection frame 41 is fixed to the top of the lower sliding frame 4, protecting the oil injection device 3 from damage caused by external debris. This ensures that the entire oil injection system can stably and continuously provide lubrication to the linear guide rail, guaranteeing long-term stable operation of the linear guide rail at high speed and low noise.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
