[0028] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0029] See Figures 1-7 As shown, a guide rail maintenance structure for a linear module includes an oil trough 11, a cover plate 2, and a felt 3.

[0030] Specifically, the oil trough 11 is set on the slide table 1 of the linear module, and the cover plate 2 is set on the slide table 1 and covers the opening of the oil trough 11. An oil storage cavity 10 for storing oil and loading felt 3 is formed between the oil trough 11 and the cover plate 2. The inner wall of the slide table 1 has a window 101 that passes through the oil trough 11. The felt 3 is loaded into the oil storage cavity 10, and the felt 3 partially passes through the window 101 to extend out of the inner wall of the slide table 1 and contact the beam rail on the linear module. The felt 3 moves back and forth on the beam rail with the slide table 1 to apply lubricant to the beam rail, so that the felt can better clean and maintain the surface of the beam rail, and make the roller 13 on the slide table 1 more lubricated and less frictional, thereby making the slide table 1 move more smoothly and with higher precision on the beam rail. The slide table 1 or the cover plate 2 is provided with an oil injection hole 21 that passes through the oil storage cavity 10. In other words, this utility model directly opens the oil tank 11 on the slide table 1 of the linear module, and inserts the felt 3 into the oil tank 11. Finally, a cover plate 2 with an oil injection hole 21 is installed on the slide table 1. Its structure is simpler and uses fewer parts. After the cover plate 2 covers the oil tank 11, it forms an oil storage cavity 10 for storing oil and loading the felt 3. The cover plate 2 also presses against the felt 3 so that the felt 3 partially passes through the window 101 and extends out of the inner wall of the slide table 1, so that the felt 3 can partially contact the beam rail to apply lubricating oil to the beam rail, so that the felt can better clean and maintain the rail surface of the beam rail. In practical use, the operator injects lubricating oil into the oil storage chamber 10 by inserting an oil injector (such as a syringe) through the oil injection hole 21 on the cover plate 2. The felt 3 located in the oil storage chamber 10 absorbs the lubricating oil, and the oil storage chamber 10 stores a certain amount of lubricating oil to ensure that the felt 3 is constantly lubricated without the need for frequent individual lubrication of the felt 3. This reduces the lubrication cycle and the number of lubrications, which can greatly reduce the intensity of manual labor. Even in poor working conditions, because the oil storage chamber 10 stores a certain amount of lubricating oil, it is not necessary to lubricate / refill the felt in a short period of time. This allows the felt to better clean and maintain the rail surface of the beam rail, making it more convenient to use and solving the problem of frequent lubrication of the felt 3.

[0031] In this embodiment, the oil trough 11 is opened inward along the outer side of the slide table 1. The slide table 1 is equipped with a plurality of rollers 13 that cooperate with the beam rail, and the outer side of the slide table 1 is also provided with a plurality of installation and maintenance holes 14 for exposing the rollers. The cover plate 2 also covers the installation and maintenance holes 14 for exposing the rollers, thus achieving a multi-purpose function.

[0032] The cover plate 2 is provided with an oil injection hole 21 extending through its front and rear ends. A plug 22 for sealing the oil injection hole 21 and a spring 23 for pressing against the plug 22 to provide elastic force are provided on the rear side of the cover plate 2. Under the elastic force of the spring 23, the plug 22 blocks the rear opening of the oil injection hole 21. This invention uses the spring 23 and the plug 22 in cooperation to seal the oil injection hole 21, forming a one-way valve structure, which is simpler in structure and uses fewer parts. In practical use, the operator inserts an oil injector (such as a syringe) into the oil injection hole 21 on the cover plate 2 and pushes the plug 22 to compress the spring 23, causing the plug 22 to leave the oil injection hole 21. At this time, the oil injector can inject lubricating oil into the oil storage chamber 10 to achieve the purpose of oil injection. When the oil injector is pulled out, the spring 23 drives the plug 22 to return to its original position and provides elastic force to the plug 22. Under the elastic force of the spring 23, the plug 22 blocks the rear opening of the oil injection hole 21, thereby sealing the oil injection hole 21 and preventing lubricating oil from leaking out of the oil injection hole 21, thus achieving the effect of preventing oil leakage.

[0033] Furthermore, the other end of the spring 23 that contacts the plug 22 contacts the felt 3 to provide elasticity to the felt 3. That is to say, the plug 22 and the felt 3 in this utility model share a spring 23, which can reduce the number of parts and make the assembly structure more compact. The spring 23 provides elasticity to both the plug 22 and the felt 3. Under the elastic force of the spring 23, the plug 22 blocks the oil injection hole 21 to seal the oil injection hole 21, and under the elastic force of the spring 23, the felt 3 partially passes through the window 101 to extend outside the inner wall of the slide table 1, so that it forms elastic contact with the beam rail rather than rigid contact in the later stage, so that the felt 3 is stably attached to the beam rail, so that the lubricating oil can be better coated on the beam rail, and the felt can better clean and maintain the rail surface of the beam rail.

[0034] The felt 3 is provided with a positioning groove 31, and the other end of the spring 23 that contacts the plug 22 is embedded in the positioning groove 31, so that the spring 23 can provide a stable elastic force to the felt 3.

[0035] The plug 22 is a spherical ball, such as a steel ball or glass bead. A blocking groove 211 is provided at the rear end opening of the oil filling hole 21. The spherical ball is embedded in the blocking groove 211 to block the oil filling hole 21, and the spherical ball can move back and forth within the blocking groove 211. Because the plug 22 is housed in the blocking groove 211, it allows the plug 22 to better seal the rear end opening of the oil filling hole 21.

[0036] In order to ensure that the spring 23 can be stably installed on the rear side of the cover plate 2, the following design is also made: a positioning cylinder 24 is provided on the rear side of the cover plate 2. The through hole 241 of the positioning cylinder 24 is connected to the rear opening of the oil injection hole 21 and the oil storage chamber 10. The plug body 22 is inserted into the through hole 241 of the plug body 22. One end of the spring 23 is sleeved in the positioning cylinder 24, and the spring 23 partially extends into the through hole 241 to press the plug body 22. Its assembly structure is simple, so that the spring 23 is stably installed on the rear side of the cover plate 2.

[0037] More specifically, the positioning cylinder 24 is also provided with a groove 242 that passes through its upper and lower surfaces and the through hole 241; one end of the spring 23 is also formed with a spring arm 231, which is placed in the middle of one end of the spring 23 and is also embedded in the groove 242, and contacts the rear end of the plug 22 to form a forward elastic force on the plug 22. Its assembly structure is stable and can also make the spring 23 more stably positioned on the periphery of the positioning cylinder 24.

[0038] The spring 23 is a tower-shaped spring with one end larger than the other. The positioning cylinder 24 is also a frustum-shaped cylinder with one end larger than the other. This makes assembly easier and allows the spring 23 to be positioned more stably around the positioning cylinder 24.

[0039] In this embodiment, there are two oil tanks 11, which are respectively located at both ends of the outer side of the slide table 1; the cover plate 2 is fixed to the outer side of the slide table 1 and covers both oil tanks 11 at the same time.

[0040] The slide 1 has a stepped groove 12 on its outer side. The cover plate 2 is embedded in the stepped groove 12 to achieve positioning and is locked with screws 15. Its assembly structure is simple and easy to install.

[0041] In summary, this utility model directly places the oil trough 11 on the slide table 1 of the linear module, and inserts the felt 3 into the oil trough 11. Finally, a cover plate 2 with an oil injection hole 21 is installed on the slide table 1. The structure is simpler and uses fewer parts. After the cover plate 2 covers the oil trough 11, it forms an oil storage cavity 10 for storing oil and loading the felt 3. The cover plate 2 also presses against the felt 3 so that the felt 3 partially passes through the window 101 and extends out of the inner wall of the slide table 1, so that the felt 3 can partially contact the beam rail to apply lubricating oil to the beam rail, so that the felt can better clean and maintain the surface of the beam rail. In practical use, the operator injects lubricating oil into the oil storage chamber 10 by inserting an oil injector (such as a syringe) through the oil injection hole 21 on the cover plate 2. The felt 3 located in the oil storage chamber 10 absorbs the lubricating oil, and the oil storage chamber 10 stores a certain amount of lubricating oil to ensure that the felt 3 is constantly lubricated without the need for frequent individual lubrication of the felt 3. This reduces the lubrication cycle and the number of lubrications, which can greatly reduce the intensity of manual labor. Even in poor working conditions, because the oil storage chamber 10 stores a certain amount of lubricating oil, it is not necessary to lubricate / refill the felt in a short period of time. This allows the felt to better clean and maintain the rail surface of the beam rail, making it more convenient to use and solving the problem of frequent lubrication of the felt 3.
