Description

Technical Field

[0001] The utility model relates to the field of linear guide rails, in particular to a linear guide rail which is easy to lubricate. Background Art

[0002] Linear guides can support and guide moving parts so that they can perform precise linear motion along a predetermined trajectory, which ensures the accuracy of the direction and position of motion and reduces motion errors and vibrations. In machine tools and other equipment, linear guides are a key high-precision mechanical component and are widely used in various automated machinery and equipment, such as CNC machine tools, industrial robots, etc. They play a vital role in ensuring the processing accuracy, running smoothness, stability and efficiency of the equipment. During the use of the linear guide, friction will occur between the linear guide and the slider, so the linear guide needs to be lubricated regularly to ensure the stability of the linear guide.

[0003] After searching, Chinese patent announcement number: CN218235837 U discloses a linear guide rail that is easy to lubricate. By setting a connecting block, a connecting rod, an oil pot, a pot cover, a positioning groove, a shell, a positioning assembly and a control assembly for coordinated use, the control rod is pressed to the left, and the control rod drives the baffle to stretch the tension spring. At the same time, the control rod drives the control column to move to the left, and the control column drives the control plate to move downward through the control groove. This solves the problem that lubrication treatment is required after the friction between the slider and the slide rail of the existing linear guide rail increases, and the original linear guide rail lacks a method for lubricating the slider and the slide rail, resulting in the linear guide rail being inconvenient to use.

[0004] In the above technical solution, the lubricating oil in the oil pot is transferred to the guide rail for lubrication through the connecting block and the connecting rod. However, a certain amount of dust will inevitably adhere to the surface of the guide rail during use. If the dust is not cleaned before lubrication, the dust will come into contact with the lubricating oil and condense into clumps and accumulate on the surface of the guide rail, which reduces the lubrication effect and is not conducive to the stability of the guide rail in subsequent use. Therefore, a linear guide rail that is easy to lubricate is proposed to solve the above problem. Utility Model Content

A Velcro hook surface 307 is fixedly connected to the surface of the rotating rod 305, and a Velcro velvet surface 308 is provided on the side of the Velcro hook surface 307 away from the rotating rod 305. The number of rotating rods 305 is equal to that of the moving block 302, and a group of Velcro hook surfaces 307, Velcro velvet surfaces 308 and sponges 309 are provided on both sides of each group of rotating rods 305. The Velcro hook surfaces 307 and the Velcro velvet surfaces 308 are adhered to each other, and the side walls of the Velcro velvet surfaces 308 are fixedly connected to the sponges 309.

[0037] Reference Figure 1-Figure 3The surface of the slider 2 is fixedly connected with an oil storage shell 312 by bolts, and an oil inlet pipe and a sealing cover are provided on the top of the oil storage shell 312. The sealing cover is threadedly connected to the oil inlet pipe. The sealing cover is removed and the lubricating oil can be poured into the interior of the oil storage shell 312 through the oil inlet pipe. The oil storage shell 312 can be made of plastic material to reduce the weight of the oil storage shell 312 itself and thus reduce the burden on the slider 2 when sliding. An avoidance groove 313 is provided on the surface of the oil storage shell 312, and an air bag 311 is provided inside the avoidance groove 313. The inner wall of the air bag 311 is fixedly connected with a telescopic hose 310.

The airbag 311 is made of soft rubber material, and an elastic part is arranged inside to help the airbag 311 to automatically reset for secondary extraction of lubricating oil. A one-way valve is arranged on the pipeline connected to the airbag 311 and the oil storage shell 312. The one-way valve allows the pipeline to only extract the lubricating oil inside the oil storage shell 312, and does not allow the lubricating oil to flow back into the oil storage shell 312.

[0039] Reference Figure 6The surface of the sponge 309 is provided with a disassembly structure 4, which includes a threaded tube 401. The inner wall of the threaded tube 401 at one end away from the sponge 309 is threadedly connected to the outer wall of the telescopic hose 310. The telescopic hose 310 is turned over so that the telescopic hose 310 is gradually separated from the threaded tube 401, which is convenient for disconnecting the sponge 309 from the telescopic hose 310.

The support column 402 is connected to the outer wall of the sponge 309, and the end of the support column 402 away from the rotating rod 305 is rotatably connected to the outer wall of the slider 2. The forward rotation of the rotating rod 305 can drive the support column 402 to rotate on the moving block 302. The reverse rotation of the rotating rod 305 cannot rotate on the moving block 302, and the external thread of the rotating rod 305 is gradually separated from the internal thread of the support column 402 until the rotating rod 305 is completely separated from the support column 402, so as to facilitate the disassembly and assembly of the rotating rod 305 as a whole from the moving block 302.

[0040] Working principle: when lubrication is required between the slider 2 and the guide rail 1, the operator first moves the slider 2 back and forth on the guide rail 1 with his hands, so that the sponges 309 close to the left and right sides of the guide rail 1 wipe the surface of the guide rail 1 to prevent dust from adhering to the surface of the guide rail 1. After the dust is wiped off by the sponges 309 on the left and right sides, the rotating knobs 306 are manually turned in turn, and the rotating rod 305 is rotated 90 degrees forward, so that the two groups of sponges 309 facing outward are in contact with the surface of the guide rail 1 in turn. At this time, the telescopic hose 310 will stretch and deform, and then press the airbag 311 in turn. After the airbag 311 is stressed, the extracted lubricating oil will be transported to the sponge 309 through the telescopic hose 310. After the sponge 309 is soaked with the lubricating oil, the slider 2 is moved again, so that the sponge 309 lubricates the contact position between the guide rail 1 and the slider 2. After the four sets of sponges 309 are used for a long time, the hand applies force to the rotating knob 306 in turn to move it away from the guide rail 1. At this time, the moving block 302 will drive the rotating rod 305 to slide inside the groove 301, so that the rotating rod 305 is away from the guide rail 1. At this time, the Velcro velvet surface 308 is torn off the Velcro hook surface 307, and then the telescopic hose 310 is rotated to separate it from the threaded tube 401, and the sponge 309 is removed for easy cleaning or replacement, thereby ensuring the lubrication effect on the guide rail 1. Finally, the rotating rod 305 is manually reversed to make the rotating rod 305 detach from the support column 402, and then the oil storage shell 312 is removed by bolts, so that the lubrication structure 3 can be quickly disassembled and assembled from the slider 2, so that the weight of the slider 2 can be reduced when the guide rail 1 and the slider 2 are disassembled as a whole, reducing the difficulty of operation for the staff.
