Description

Technical Field

[0001] The utility model relates to the technical field of sliders, in particular to a novel slider with high efficiency lubrication. Background Art

[0002] In the field of linear transmission, linear guide devices have always been key products. At present, they have become important functional components that are indispensable in various machine tools, CNC machining centers, and precision electronic machinery. There are many ways to use linear guide pairs, such as positive installation, oblique installation, and side installation.

[0003] In the prior art, in order to reduce the friction between the slider and the linear guide and ensure the continuous sliding stability of the slider, the slider structure generally adopts a ball structure or a roller structure to reduce the friction between the slider and the guide rail. The rolling friction of the ball structure or the roller structure replaces the sliding friction between the slider and the linear guide, thereby improving the stability of the slider's movement on the linear guide and the transmission effect.

[0004] However, in actual use of the above-mentioned equipment, a slider with a ball is generally provided with a lubrication structure at the end of the slider when it is in use. By continuously providing lubricating oil to the ball, the friction of the ball during transmission between the linear guide and the slider is further reduced to avoid the ball from getting stuck. However, since the lubrication structure generally uses oil dripping to achieve oil coating on the surface of the ball, and relies on the rolling of the ball itself to achieve uniform coating, the coating effect of the lubricating oil on the surface of the ball is completely dependent on the rolling of the ball itself, which makes the coating effect of the lubricating oil poor and reduces the efficiency of the lubricating oil in lubricating the ball arranged in the slider. In view of this, we propose a new slider with high-efficiency lubrication. Utility Model Content

[0005] The purpose of the utility model is to provide a novel sliding block with high efficiency lubrication to solve the problems raised in the above background technology.

[0011] Preferably, the covering assembly is arranged near the port of the reflux chamber, and the mounting ring is arranged vertically, and the inner diameter of the silicone ring is matched with the outer diameter of the ball, so that the ball can just pass through the internal space of the silicone ring during the rolling process.

DETAILED DESCRIPTION

[0026] like Figure 1-Figure 7As shown, the utility model provides a technical solution: a new type of efficient lubrication slider, including a slider 1 and a guide rail 2 for installing the slider 1, an end cover 3 is fixedly installed at the end of the slider 1, an end face sealing sheet 4 is fixedly installed on the outer wall of the end cover 3 on the side away from the slider 1, a grease nipple 5 is fixedly installed on the inner wall of the end face sealing sheet 4, an internal sealing sheet 6 is fixedly installed on the inner surface of the slider 1, a retainer 7 is fixedly installed on the bottom inner surface of the slider 1, a bottom surface sealing sheet 8 is fixedly installed on the bottom inner surface of the slider 1, a reflux cavity 9 is opened on the inner wall of the slider 1, a ball 10 is arranged inside the reflux cavity 9, a covering component 11 is arranged inside the reflux cavity 9, and the covering component 11 includes a mounting ring 111, a movable ring 112, a silicone ring 113, a bevel 114, a small scraper 115, bristles 116 and a bending groove 117.

[0027] In one embodiment of the utility model, an annular cavity is provided on the inner wall of the reflux cavity 9, a mounting ring 111 is fixedly installed on the inner wall of the annular cavity, a movable ring 112 is movably installed on the inner wall of the mounting ring 111, a silicone ring 113 is fixedly installed on the arc-shaped inner surface of the movable ring 112, beveled edges 114 are provided on both sides of the arc-shaped inner surface of the silicone ring 113, a small scraper 115 is fixedly installed on the arc-shaped inner surface of the silicone ring 113, bristles 116 are arranged on the arc-shaped inner surface of the silicone ring 113, and a curved groove 117 is provided on the arc-shaped inner surface of the silicone ring 113.

[0028] Furthermore, the end face of the guide rail 2 is arranged in an "I" shape, and the side grooves of the guide rail 2 are provided with flat surfaces to facilitate the movement of the ball 10. At the same time, a groove adapted to the guide rail 2 is provided at the bottom of the slider 1 to facilitate the slider 1 to move linearly on the guide rail 2, ensuring that there is sufficient contact area between the two to avoid the slider 1 not being able to obtain sufficient supporting force and affecting the transportation capacity of the linear transmission. In addition, there are two groups of end covers 3, and the two groups of end covers 3 are symmetrically arranged with the vertical central axis of the slider 1 as the symmetry axis, so that the grease nozzles 5 corresponding to the two groups of end covers 3 can be on the slider. The front and rear ends of the block 1 are provided with lubricating oil to ensure that the slider 1 can maintain high lubrication and movement performance during the round trip of linear motion. Specifically, there are two groups of retainers 7, and the two groups of retainers 7 are respectively arranged on the upper and lower sides of the bottom groove of the slider 1, and there are two groups of reflux chambers 9 to provide sufficient contact area between the slider 1 and the guide rail 2 to ensure that the slider 1 is stably stressed on the guide rail 2 and improve the stability of the device operation. At the same time, there are several groups of balls 10, and the several groups of balls 10 are evenly distributed inside the reflux chamber 9.

[0029] In addition, the covering component 11 is arranged near the port of the reflux chamber 9, and the mounting ring 111 is arranged vertically. Specifically, the inner diameter of the silicone ring 113 is adapted to the outer diameter of the ball 10, so that the ball 10 can just pass through the internal space of the silicone ring 113 during the rolling process, thereby avoiding the ball 10 from getting stuck or detaching near the covering component 11. At the same time, an annular groove adapted to the size of the movable ring 112 is opened on the arc-shaped inner wall of the mounting ring 111 to facilitate the movable ring 112 to move freely in the annular groove. Furthermore, the silicone ring 113 itself is made of silicone material, so that it is easy to deform and better adapt to the spherical outer surface of the ball 10. Specifically, the number of curved grooves 117 is arranged in several groups, and several groups of curved grooves 117 are evenly distributed on the arc-shaped inner surface of the silicone ring 113 in a circular array, thereby dividing the arc-shaped inner surface of the silicone ring 113 into a plurality of small intervals, and the bristles 116 and the small scraper 115 are both arranged in the small intervals.

[0030] In the embodiment of the utility model, the curved groove 117 is set to be S-shaped, so as to prolong the retention time of the lubricating oil passing through the silicone ring 113, so that the silicone ring 113 can not only scrape the lubricating oil attached to the outer surface of the ball 10, but also play a certain accumulation effect, avoid the waste of lubricating oil, and provide lubricating oil for the next group of moving balls 10, improve the stability of the ball 10 running in the reflux chamber 9, and then ensure the stability of the operation between the slider 1 and the guide rail 2. Further, the small scraper 115 is set to be curved, and the small scraper 115 itself is made of silicone. Specifically, the brush The bristles 116 are arranged in a linear pattern within the small intervals on the curved inner surface of the silicone ring 113, and the small scraper 115 is arranged in the gap between two adjacent rows of bristles 116. Thus, the inclined small scraper 115 can not only scrape and cover the lubricating oil attached to the surface of the moving ball 10, but also cause the ball 10 to drive the movable ring 112 to rotate slightly during operation due to its inclined shape, thereby improving the effect of the bristles 116 on leveling the lubricating oil on the surface of the ball 10, so that the surface of the ball 10 can be lubricated, thereby ensuring the stable operation of the ball 10 and the slider 1.

[0031] In the utility model, when in use, when the slider 1 makes a linear motion along the outer surface of the guide rail 2, it is connected to the grease nipple 5 through an external device, and oil is continuously supplied to the connection between the slider 1 and the guide rail 2, thereby reducing the friction of the ball 10 and improving the stability of the slider 1 moving on the guide rail 2. At the same time, by providing a covering component 11 and cooperating with a plurality of small scrapers 115 inclinedly arranged on the arc-shaped inner surface of the silicone ring 113, the ball 10 can be scraped and leveled by the small scrapers 115 during the movement, thereby making the lubricating oil coated on the surface of the ball 10 more uniform, ensuring the overall lubricity of the ball 10 and avoiding excessive lubricating oil in a certain place affecting the normal operation of the slider 1. At the same time, the inclined small scrapers 115 can also promote the rolling of the ball 10 to drive the rotation of the movable ring 112, thereby improving the leveling effect of the bristles 116 on the lubricating oil on the surface of the ball 10, so that the surface of the ball 10 can be lubricated, ensuring the stable operation of the ball 10 and the slider 1.

[0032] 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 depart from the spirit of the present invention are within the scope of protection of the present invention.
