Description

Technical Field

[0001] The utility model relates to the technical field of linear guide rails, in particular to a high-speed precision roller linear guide rail. Background Art

[0002] Linear guides are generally divided into roller linear guides and ball linear guides. Ball linear guides are mainly used in mechanical structures with relatively high precision requirements. The moving elements and fixed elements of the linear guide use rolling steel balls as connecting materials, while roller linear guides are mainly used in automated machinery.

[0003] The utility model patent application document with publication number "CN215928131U" discloses a high-speed precision roller linear guide, which is mainly composed of a track and a slider. This technical solution sets up a high-speed precision roller linear guide, which uses steel balls and guide rails whose outer surfaces are precisely ground and hardened. When the slider slides on the rail, the original sliding friction is changed to rolling friction, which greatly reduces the original friction coefficient and resistance between the two, and greatly reduces the gap between the two groups, thereby improving mechanical efficiency and making the movement process more high-speed and precise.

[0004] The high-speed precision roller linear guide disclosed in the above document has the following defects: in the prior art, the slider slides on the surface of the slide rail, and the movement of the slider drives the object to move. During the long-term use of the slider and the slide rail, the surface of the slide rail is very easy to absorb dust. The dust is absorbed in the gaps of the slide rail, which is inconvenient to clean and may affect the normal use of the slider on the slide rail.

[0005] It can be seen from this that the existing high-speed precision roller linear guide does not have a structure for cleaning dust, and it is necessary to improve the existing deficiencies and provide a high-speed precision roller linear guide. Utility Model Content

[0006] The purpose of the utility model is to provide a high-speed precision roller linear guide to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0008] The utility model is a high-speed precision roller linear guide rail, comprising a slide rail and a slider, the slider being slidably connected to the outer surface of the slide rail, the slider comprising a connecting block, both ends of the connecting block being provided with end covers, the upper surface of the end cover being provided with a placement block, the placement block being mounted on the upper surface of the end cover by bolts, a cleaning assembly being provided inside the end cover, an oil storage tank being provided inside the connecting block, a cover plate being provided on the upper surface of the oil storage tank, the cover plate being mounted on the outer surface of the end cover by bolts, a connecting piece being provided on the inner surface of the oil storage tank, a roller being rotatably connected to the interior of the connecting piece, and an oil inlet hole being provided on the upper surface of the cover plate.

[0009] Furthermore, an oil storage sponge is provided inside the oil storage tank.

[0010] Furthermore, the cleaning assembly includes a frame, a cleaning block is arranged inside the frame, an outer surface of the cleaning block is provided with a mounting groove, an inner top of the frame is provided with a mounting block, the mounting block is fitted and installed inside the mounting groove, and the inner surface of the cleaning block is provided with bristles.

[0011] Furthermore, a first limit block is provided on the outer surface of the frame, and the frame is mounted in cooperation with the inside of the end cover. A slide groove is provided on the outer surface of the first limit block, a baffle is installed at one end of the slide groove, a slide is slidably connected to the inside of the slide groove, a spring is provided at one end of the slide groove, and the other end of the spring is mounted on the inner surface of the slide groove. A second limit block is provided at the other end of the slide, and one end of the second limit block passes through the baffle and extends outward.

[0012] Furthermore, a limiting groove is provided on the inner surface of the end cover, and a first limiting block is installed inside the limiting groove. A mounting hole is provided on the outer surface of the end cover, and one end of the mounting hole extends to the inside of the limiting groove, and a second limiting block is installed inside the mounting hole.

[0013] Furthermore, one end of the second limiting block is provided with an inclined surface.

[0014] The utility model has the following beneficial effects:

[0015] (1) The cleaning block provided in the present invention can clean the outer surface of the slide rail to prevent dust from affecting the normal use of the slider on the slide rail. At the same time, by squeezing the second limit block, the second limit block is gradually separated from the inside of the installation groove. At the same time, the slide moves in the slide groove and the spring gradually contracts. When the second limit block is completely separated from the installation hole, the slide block can be slid to one side to separate the first limit block from the inside of the limit groove, thereby completing the separation of the end cover and the frame, and then facilitating the replacement of the cleaning block in the frame, thereby achieving a better practical effect.

[0016] (2) The utility model can inject lubricating oil into the oil storage tank through the oil inlet hole, so that the lubricating oil soaks the oil storage sponge. When the oil storage sponge is completely soaked, the injection of lubricating oil is stopped. During the rolling process of the roller, the outer surface of the roller will contact the oil storage sponge, so that the lubricating oil in the oil storage sponge is coated on the outer surface of the roller to lubricate the roller. The lubricating oil can reduce the friction resistance between the roller and the slide rail, thereby extending the service life of the roller and the slide rail.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] When the slider 2 moves on the slide rail 1, the slide rail 1 can be cleaned by the provided cleaning component 3 to prevent dust from affecting the normal use of the slider 2 on the slide rail 1;

[0029] An oil storage sponge 4 is provided inside the oil storage tank 204;

[0030] Before use, lubricating oil can be injected into the oil reservoir 204 through the oil inlet hole so that the lubricating oil soaks the oil storage sponge 4. When the oil storage sponge 4 is completely soaked, the injection of lubricating oil is stopped. During the rolling process of the roller 206, the outer surface of the roller 206 comes into contact with the oil storage sponge 4, so that the lubricating oil in the oil storage sponge 4 is coated on the outer surface of the roller 206, lubricating the roller 206. The lubricating oil can reduce the friction resistance between the roller 206 and the slide rail 1, thereby extending the service life of the roller 206 and the slide rail 1.

[0031] The cleaning assembly 3 includes a frame 301, a cleaning block 302 is disposed inside the frame 301, a mounting groove 303 is provided on the outer surface of the cleaning block 302, a mounting block 304 is provided on the inner top of the frame 301, the mounting block 304 is mounted inside the mounting groove 303, and bristles are provided on the inner surface of the cleaning block 302;

[0032] When the slider 2 moves on the slide rail 1, the push frame 301 and the cleaning block 302 move on the slide rail 1, so that the bristles of the cleaning block 302 clean the outer surface of the slide rail 1;

[0033] A first stopper 305 is provided on the outer surface of the frame 301, which is mounted in conjunction with the interior of the end cover 202. A sliding groove is provided on the outer surface of the first stopper 305, one end of which is mounted with a baffle 306. A slide plate 307 is slidably connected to the interior of the slide plate. A spring 308 is provided at one end of the slide plate 307, the other end of which is mounted on the inner surface of the slide plate. A second stopper 309 is provided at the other end of the slide plate 307, one end of which passes through the baffle 306 and extends outward.

[0034] The inner surface of the end cover 202 defines a limiting groove 207, and a first limiting block 305 is mounted in the limiting groove 207. The outer surface of the end cover 202 defines a mounting hole 208, and one end of the mounting hole 208 extends into the limiting groove 207. A second limiting block 309 is mounted in the mounting hole 208.

[0035] One end of the second limiting block 309 is provided with an inclined surface;

[0036] When the cleaning block 302 needs to be replaced, the second limiting block 309 is squeezed to gradually disengage from the inside of the mounting hole 208. At the same time, the slide plate 307 moves in the slide groove and the spring 308 gradually contracts. When the second limiting block 309 is completely disengaged from the mounting hole 208, the slide block 2 can be slid to one side to disengage the first limiting block 305 from the inside of the limiting groove 207, thereby completing the separation of the end cover 202 and the frame 301. By pulling the frame 301 upward, the cleaning block 302 is removed from the slide rail 1, and then the cleaning block 302 is pulled downward to separate the frame 301 and the cleaning block 302. Then, the new cleaning block 302 is placed directly under the frame 301, and the cleaning block 302 is pushed upward so that the mounting block 304 is fitted and installed in the mounting groove 303, completing the installation of the frame 301 and the cleaning block 302. After that, the frame 301 is installed on the slide rail 1, and the cleaning block 302 is cooperated and installed on the outer surface of the slide rail 1 by pushing the slider 2, and the frame 301 is cooperated and installed inside the end cover 202 by pushing the slider 2. At the same time, the first limit block 305 is cooperated and installed inside the limit groove 207. When the second limit block 309 contacts the outer surface of the limit groove 207, due to the outer surface of the second limit block 309 having an inclined surface, the second limit block 309 will push the slide plate 307 inward, so that the slide plate 307 moves toward the inside of the slide groove. At the same time, the spring 308 gradually contracts. When the second limit block 309 is located on one side of the mounting hole 208, the spring 308 restores its elasticity and pushes the slide plate 307 to reset, so that the second limit block 309 is cooperated and installed inside the mounting hole 208, thereby completing the fixed installation of the cleaning component 3 and the slider 2.
