Description

A slider assembly for a linear guide rail Technical Field

[0001] This utility model relates to the field of linear slider technology, specifically a slider assembly for linear slide rails. Background Technology

[0002] Linear guides can be divided into three types: roller linear guides, cylindrical linear guides, and ball linear guides. They are used to support and guide moving parts to perform reciprocating linear motion in a given direction. According to the nature of friction, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides, etc. Linear guides are also called linear rails, slide rails, or linear guides. A slider is a component in a linear slide rail that can slide in a certain direction or angle and is one of the essential components of a linear slide rail.

[0003] When a linear guide is in operation, lubricating oil is usually applied to the outer wall of the linear guide to lubricate the connection between the linear guide and the linear slider. However, dust and other impurities in the air can easily adhere to the lubricating oil, causing them to enter the linear bearing inside the linear slider. This can lead to wear on the linear bearing and affect the service life of the linear guide and the slider. Existing slider assemblies generally have dust covers at the ends to prevent dust from entering the device. However, because the connection between the dust cover and the linear guide is relatively tight, the lubrication effect is not good. To improve the service life, a slider assembly for linear guides is proposed. Technical issues

[0004] The purpose of this invention is to provide a slider assembly for linear guideways in order to solve the problem of short service life. Technical solutions

[0005] To achieve the above objectives, the present invention provides the following technical solution: a slider assembly for a linear guide rail, comprising a linear slider and an oil reservoir, wherein the two ends of the linear slider are symmetrically provided with lubrication mechanisms for lubricating the linear guide rail;

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 4. In this embodiment of the present invention, a slider assembly for a linear guide rail includes a linear slider 1 and an oil reservoir 2. The two ends of the linear slider 1 are symmetrically provided with lubrication mechanisms 3 for lubricating the linear guide rail. The lubrication mechanism 3 includes a lubrication sleeve 301, an end cap 302, an oil scraper sleeve 303, and a lubricating cotton 304. The lubrication sleeve 301 is installed at one end of the linear slider 1, and the end cap 302 is threaded to the end of the lubrication sleeve 301 away from the linear slider 1. The end cap 302 has a through hole formed inside. The oil scraper sleeve 303 is bonded to one end of the inner wall of the end cap 302. The lubricating cotton 304 is snapped and fixed inside the lubrication sleeve 301 and extends into the oil reservoir 2. A linear bearing is installed inside the linear slider 1 by means of a retaining ring. The vertical cross-section of the oil reservoir 2 is convex. The top of the oil reservoir 2 has an oil injection hole.

[0023] In this embodiment: During the sliding motion of the linear slider 1 along the outer wall of the linear guide rail via the linear bearing, the lubricating cotton 304 applies lubricating oil to the outer wall of the linear guide rail, further reducing the sliding wear between the linear slider 1 and the linear guide rail. At the same time, the bottom end of the lubricating cotton 304 extends into the oil reservoir 2, allowing the oil reservoir 2 to supply lubricating oil to the lubricating cotton 304. During the sliding motion of the linear slider 1, the scraper sleeve 303 scrapes and cleans the lubricating oil applied to the outer wall of the linear guide rail, collecting the lubricating oil inside the lubricating sleeve 301. Through the coordinated use of the above parts, during the sliding motion of the linear slider 1, the scraper sleeve 303 scrapes and cleans the lubricating oil applied to the outer wall of the linear guide rail, and cleans dust and other impurities from the outer wall of the linear guide rail, collecting the lubricating oil inside the lubricating sleeve 301. This separates the lubricating oil from the dust, effectively preventing dust and other impurities from adhering to the lubricating oil and entering the linear bearing inside the linear slider 1, thereby preventing dust and other impurities from causing wear on the linear bearing and greatly improving the service life of the guide rail and slider.

[0024] Please refer to Figures 1, 3 and 4. The lubrication mechanism 3 also includes a partition 305 and a soft rubber sleeve 306. The partition 305 is symmetrically installed at both ends of the lubrication cotton 304 inside the lubrication sleeve 301. The soft rubber sleeve 306 is fitted onto the lower outer wall of the lubrication cotton 304.

[0025] In this embodiment: the upper part of the lubricating cotton 304 is limited and installed inside the lubricating sleeve 301 by the partition 305, and the soft rubber sleeve 306 makes a soft connection between the lubricating sleeve 301 and the oil reservoir 2, and the soft rubber sleeve 306 protects the lower outer wall of the lubricating cotton 304.

[0026] Please refer to Figures 1, 2 and 3. The outer walls of the linear slider 1 are provided with connecting grooves 4 that match the outer walls of the lubrication sleeve 301. The outer walls of the lubrication sleeve 301 are symmetrically welded with first connecting ears 5, and the outer walls of the oil reservoir 2 are symmetrically welded with second connecting ears 6.

[0027] In this embodiment: by inserting one end of the lubrication sleeve 301 into the connecting groove 4, two lubrication sleeves 301 are symmetrically installed at both ends of the linear slider 1. A first bolt is used to pass through the two first connecting ears 5 and the second connecting ears 6 on one side of the outer wall of the linear slider 1. A first nut is threaded onto the outer wall of the first bolt, so that the two first connecting ears 5 and the second connecting ears 6 on the outer wall of the linear slider 1 are connected and fixed. Then, a second bolt is used to pass through the two first connecting ears 5 and lock them in place. Similarly, the two first connecting ears 5 and the second connecting ears 6 on the other side of the outer wall of the linear slider 1 are connected and fixed, thereby fixing the two lubrication sleeves 301 and the oil reservoir 2 to the outer wall of the linear slider 1.

[0028] Please refer to Figures 1 and 4. The bottom end of the lubrication sleeve 301 is formed with a bottom hole for the lubricating cotton 304 to pass through to the outside of the lubrication sleeve 301. The top ends of the oil reservoir 2 are symmetrically formed with top holes. The top end of the soft rubber sleeve 306 is bonded and fixed to the bottom end of the lubrication sleeve 301, and the bottom end of the soft rubber sleeve 306 is bonded and fixed to the top end of the oil reservoir 2.

[0029] In this embodiment: by setting a bottom hole and a top hole, the lubricating cotton 304 passes through the inside of the lubricating sleeve 301 into the inside of the oil storage tank 2, so that the lubricating oil stored in the oil storage tank 2 is guided through the bottom end of the lubricating cotton 304 to the top end of the lubricating cotton 304, thereby the lubricating cotton 304 coats the outer wall of the linear slide rail with oil, so that the linear bearing is lubricated when it comes into contact with the linear slide rail.

[0030] Please refer to Figure 4 for details. The outer wall of the partition 305 has several through holes arranged at equal angles.

[0031] In this embodiment: after the oil scraper sleeve 303 scrapes off the lubricant from the outer wall of the linear slide rail, the lubricant is guided into the lubricating sleeve 301. By opening a through hole, the lubricant can flow through the through hole and pass through the partition 305, so that the lubricant can be absorbed into the lubricating cotton 304 again for application.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
