[0026] like Figure 1-Figure 7 As shown, the utility model provides a technical solution: a linear guide slider with good stability, including a slider body 1, slide grooves 2 are opened on both sides of the slider body 1, and a cleaning mechanism 3 for improving the stability of the slider body 1 is arranged on the slider body 1. The cleaning mechanism 3 is provided with two groups, and the two groups of cleaning mechanisms 3 are respectively located on both sides of the slider body 1. By setting up two groups of cleaning mechanisms 3, the slider can clean impurities on the linear guide while moving, thereby avoiding metal powder from getting stuck in the connection between the slider body 1 and the linear guide, affecting the stability of the movement of the slider body 1.
[0027] The cleaning mechanism 3 comprises a triangular cover 31, a rotating shaft 32, a brush 33, a scraper 34, a spring 35, a rubber wheel 36, a cam groove 37 and a slide rod 38; the triangular cover 31 is slidably connected to the inner wall of the slide groove 2, and two sets of scrapers 34 are fixedly installed at the bottom of the triangular cover 31. When the slider body 1 moves on the linear guide rail, the two sets of scrapers 34 located at the bottom of the triangular cover 31 will push away larger impurities on the linear guide rail, and make the impurities fit on the inclined surface of the scraper 34 and move toward the two sides of the linear guide rail, so that the impurities can be discharged to the two sides of the linear guide rail. A spring 35 is fixedly installed at the bottom of the triangular cover 31, and one end of the spring 35 away from the triangular cover 31 is fixedly installed on the inner wall of the slide groove 2. When the slider body 1 is installed on the linear guide rail, the triangular cover 31 can be pulled downward by the elasticity of the spring 35, so that the triangular cover 31 can drive the bottom of the scraper 34 to fit on the upper surface of the linear guide rail, and the rotating shaft 32 is rotatably connected to the inner wall of the triangular cover 31. The outer wall of the rotating shaft 32 is fixedly installed with a rubber wheel 36, and the bottom of the rubber wheel 36 is flush with the bottom of the scraper 34. When the slider body 1 moves on the linear guide, it will drive the rubber wheel 36 to roll on the surface of the linear guide, and then the rubber wheel 36 drives the rotating shaft 32 to rotate. A cam groove 37 is opened on the rotating shaft 32, and the brush 33 is slidably connected to the inner wall of the triangular cover 31, and the brush 33 penetrates the triangular cover 31. Through the lateral reciprocating movement of the brush 33, some fine metal powder on the linear guide can be swept to both sides of the linear guide, so that the metal powder is discharged from the linear guide to prevent the metal powder from getting stuck in the connection between the slider body 1 and the linear guide. A sliding rod 38 is fixedly installed on the side wall of the brush 33, and the end of the sliding rod 38 away from the brush 33 is in contact with the inner wall of the cam groove 37. The rotation of the rotating shaft 32 cooperates with the cam groove 37 to reciprocate the sliding rod 38, so that the sliding rod 38 drives the brush 33 to move laterally reciprocatingly on the inner wall of the triangular cover 31.
[0028] The brush 33 is provided with an auxiliary mechanism 4 for improving the cleaning effect. By providing the auxiliary mechanism 4, the linear guide rail cleaned by the brush 33 can be wiped, thereby further improving the cleaning effect of impurities. The auxiliary mechanism 4 includes an L-rod 41, a cross plate 42, and a sponge 43; the L-rod 41 is fixedly installed on the side wall of the brush 33, and the cross plate 42 is fixedly installed on the bottom of the L-rod 41. When the brush 33 reciprocates laterally, the sponge 43 can be driven to reciprocate synchronously in cooperation with the L-rod 41 and the cross plate 42. The sponge 43 is fixedly installed on the lower surface of the cross plate 42. The reciprocating movement of the sponge 43 can wipe the linear guide rail cleaned by the brush 33, thereby further improving the cleaning effect of impurities.
[0029] Working principle: When the slider body 1 is installed on the linear guide, the elasticity of the spring 35 can pull the triangular cover 31 downward, so that the triangular cover 31 can drive the bottom of the scraper 34 to fit the upper surface of the linear guide. At the same time, the rubber wheel 36 will also fit the upper surface of the linear guide. When the slider body 1 moves on the linear guide, the two groups of scrapers 34 at the bottom of the triangular cover 31 will push away the larger impurities on the linear guide, and make the impurities fit on the inclined surface of the scraper 34 and move to both sides of the linear guide, so that the impurities can be discharged to both sides of the linear guide. When the slider body 1 moves on the linear guide, The rubber wheel 36 will be driven to roll against the surface of the linear guide rail, and then the rubber wheel 36 will drive the rotating shaft 32 to rotate. The rotation of the rotating shaft 32 and the cam groove 37 can reciprocate and squeeze the slide bar 38, and then the slide bar 38 drives the brush 33 to move back and forth laterally on the inner wall of the triangular cover 31. The lateral reciprocating movement of the brush 33 can sweep some fine metal powder on the linear guide rail to both sides of the linear guide rail, so that the metal powder is discharged from the linear guide rail, avoiding the metal powder from getting stuck in the connection between the slider body 1 and the linear guide rail, which can not only improve the stability of the slider body 1 during operation, but also improve the service life of the slider body 1.
[0030] While the brush 33 moves back and forth laterally, it cooperates with the L rod 41 and the cross plate 42 to drive the sponge 43 to move back and forth synchronously. The reciprocating movement of the sponge 43 can wipe the linear guide rail cleaned by the brush 33, further improving the cleaning effect of impurities, and effectively preventing small metal impurities from entering the connection between the slider body 1 and the linear guide rail.
[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
