Description

Technical Field

[0001] This utility model relates to the field of flow calibration technology, and in particular to a linear guide rail with self-lubricating effect. Background Technology

[0002] Linear guides, also known as linear guides or linear slides, are mechanical transmission components used to guide and support moving parts, enabling them to move with high precision and low friction along a specific straight line. Linear guides are typically manufactured with high precision, enabling high-precision positioning and linear motion of moving parts. The structure of linear guides is relatively simple, and there are various installation methods. They can usually be installed by bolt connection or by the cooperation of sliders and guide rail slots.

[0003] In existing technologies, during the sliding process of the slider of a linear guide, the steel ball will rub against the linear rolling slider, so lubricating oil needs to be added to reduce the frictional loss between the steel ball and the linear rolling slider.

[0004] An existing patent (publication number: CN219388435U) discloses a linear guide rail with a good lubrication system. The automatic lubrication system uses a compression component to squeeze the upper end of a sponge, thereby squeezing out lubricating oil from the sponge. The lubricating oil slowly drips into a vertical pipe, gradually dripping onto a rolling steel ball, evenly covering the ball and thus lubricating the entire ball and improving the lubrication effect. By pushing a cylinder, the sponge can be automatically and repeatedly squeezed, increasing the degree of automation.

[0005] To address the aforementioned issues, while existing patents have proposed solutions that can effectively lubricate the sponge by using a cylinder to compress it, the lubricant is located inside the slider, resulting in a small storage space. Consequently, the lubricant needs to be replenished frequently, making the process somewhat cumbersome. Summary of the Invention

[0006] The purpose of this invention is to provide a linear guide rail with a self-lubricating effect, which enables the linear guide rail to achieve a self-lubricating effect, while increasing the storage space for lubricating oil through the storage cavity, thus avoiding the troublesome need to frequently add lubricating oil, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a linear guide rail with self-lubricating effect, including a top plate, an mounting block fixedly installed at the bottom end of the top plate, and a base plate fixedly installed at the bottom end of the mounting block. A slider is slidably connected to the outer wall of the top plate, and an oil injection hole is opened on one side of the top of the top plate. A storage cavity is opened at the top of the inner part of the mounting block, and a flow groove is opened on one side of the storage cavity. A lubrication mechanism is provided at the lower part of the inner part of the mounting block.

[0008] The lubrication mechanism includes an abutting roller that extends through one side of the axial outer wall of the slider, and a first spring is embedded at one end of the slider. A lubrication cavity is provided inside the lower part of the mounting block, and a through hole is provided on one side of the lubrication cavity.

[0009] Preferably, a sliding plate is slidably connected inside the lubrication cavity, and a sponge block is embedded on one side of the sliding plate inside the lubrication cavity.

[0010] Preferably, an oil outlet hole is provided on the other side of the interior of the lubrication cavity, and a second spring is embedded on one side of the through hole inside the lubrication cavity.

[0011] Preferably, the lubrication cavity is connected to the storage cavity, and the lubrication cavity and the sliding plate form a sliding structure.

[0012] Preferably, a limiting block is fixedly installed on the outer wall of the sliding plate, and a conveying mechanism is provided inside the lubrication cavity at the position corresponding to the limiting block.

[0013] Preferably, a limiting groove is provided on both sides of the inside of the lubrication cavity corresponding to the position of the limiting block, and a vertical groove is provided at the bottom of the inside of the lubrication cavity.

[0014] Preferably, a transverse groove is provided on one side of the vertical groove at the bottom of the lubrication cavity, and a conveying groove is provided on the other side of the transverse groove at the bottom of the lubrication cavity.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, multiple storage cavities are interconnected through a flow channel. Under the pressure of the contact roller, the sliding plate moves and presses the sponge block, allowing the lubricating oil to pass through the oil outlet hole. This enables the linear guide to achieve a self-lubricating effect. At the same time, the storage cavities increase the lubricating oil storage space, avoiding the inconvenience of frequently adding lubricating oil.

[0017] 2. This utility model connects the vertical and horizontal grooves. When the limiting block moves with the sliding plate, a pushing pressure is generated inside the vertical groove, which allows excess lubricating oil to pass through the conveying groove, further improving the self-lubricating function and enhancing the lubrication effect when the slider slides.

[0027] 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.

[0028] This utility model provides a technical solution:

[0029] Please see Figures 1 to 6A self-lubricating linear guide rail includes a top plate 1, a mounting block 2 fixedly mounted on the bottom end of the top plate 1, a bottom plate 3 fixedly mounted on the bottom end of the mounting block 2, a slider 4 slidably connected to the outer wall of the top plate 1, an oil injection hole 5 opened on one side of the top of the top plate 1, a storage cavity 6 opened at the top of the inner part of the mounting block 2, a flow groove 7 opened on one side of the storage cavity 6, and a lubrication mechanism 8 arranged at the lower part of the inner part of the mounting block 2; the lubrication mechanism 8 includes an abutment roller 801, the abutment roller 801 protruding through one side of the axial outer wall of the slider 4, and the abutment roller 801 located at one end of the slider 4. The mounting block 2 has a lubrication cavity 803 at its lower part, with a first spring 802 embedded inside. A through hole 804 is provided on one side of the lubrication cavity 803. A sliding plate 805 is slidably connected inside the lubrication cavity 803. A sponge block 806 is embedded on one side of the sliding plate 805 inside the lubrication cavity 803. An oil outlet hole 807 is provided on the other side of the lubrication cavity 803. A second spring 808 is embedded on one side of the through hole 804 inside the lubrication cavity 803. The lubrication cavity 803 communicates with the storage cavity 6. The lubrication cavity 803 and the sliding plate 805 form a sliding structure.

[0030] By adopting the above technical solution, the top plate 1, mounting block 2, and bottom plate 3 are integrated to form the guide rail body. The slider 4 slides along the guide rail body, injecting lubricating oil into the storage cavity 6 through the oil injection hole 5. The storage cavities 6 are interconnected through the flow groove 7, thus accommodating a large amount of lubricating oil and avoiding the inconvenience of frequent replenishment. The lubricating oil flows through the through hole of the storage cavity 6 to the lubrication cavity 803 and is absorbed by the sponge block 806. When the slider 4 moves, the abutment roller 801 moves along with it until it passes through the corresponding through hole 804 under the push of the first spring 802, pressing the sliding plate 8. 05 Pressing the sponge block 806 allows lubricating oil to pass through the oil outlet 807. The through hole 804 and the oil outlet 807 are alternately opened on both sides of the outer wall of the mounting block 2, so as to fully provide self-lubrication to both sides of the guide rail body, avoiding the troublesome need for workers to apply lubricating oil, and achieving an automated effect. The contact roller 801 easily follows the slider 4 to roll away from the through hole 804, and then the second spring 808 elastically contracts to reset the sliding plate 805. Three sets of first springs 802 are set and one set of second springs 808 are set. The pushing force is sufficient to make the second spring 808 contract.

[0031] Specifically, such as Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, a limiting block 9 is fixedly installed on the outer wall of the sliding plate 805. A conveying mechanism 10 is provided inside the lubrication cavity 803 at the position corresponding to the limiting block 9. Limiting grooves 1001 are opened on both sides of the lubrication cavity 803 at the position corresponding to the limiting block 9. A vertical groove 1002 is opened at the bottom of the lubrication cavity 803. A horizontal groove 1003 is opened on one side of the vertical groove 1002 at the bottom of the lubrication cavity 803. A conveying groove 1004 is opened on the other side of the horizontal groove 1003 at the bottom of the lubrication cavity 803.

[0032] By adopting the above technical solution, the sliding plate 805 first slides along the limiting groove 1001 and the vertical groove 1002 through the limiting block 9, which can improve the stability of the sliding plate 805 during the sliding process and avoid deviation and skew, which would cause insufficient pressure on the pressing sponge block 806. When the squeezed lubricating oil does not pass through the oil outlet 807, part of it is reabsorbed into the sponge block 806, and part of it enters the vertical groove 1002. During the displacement process of the limiting block 9, pressure is generated, which allows the lubricating oil to enter the horizontal groove 1003 through the vertical groove 1002 for collection, and then flow through the conveying groove 1004 and out of the mounting block 2, which can further play a self-lubricating role on the outer wall of the guide rail body and improve the overall lubrication effect.

[0033] Working principle: The top plate 1, mounting block 2, and bottom plate 3 form the guide rail body. The slider 4 slides along the guide rail body. The oil injection hole 5 on the top plate 1 facilitates the injection of lubricating oil into the storage cavity 6 on the mounting block 2. The multiple storage cavities 6 are connected through the flow groove 7. The through hole at the bottom of the storage cavity 6 facilitates the flow of lubricating oil into the lubrication cavity 803, where it is adsorbed by the sponge block 806. The outer wall of the mounting block 2 has through holes 804 equidistantly arranged on the left and right sides. When the slider 4 slides and abuts against the roller 801 corresponding to the through hole 804, the first spring 802 pushes the sliding plate 805 to move, squeezing the sponge block 806, thereby allowing the lubricating oil to be concentrated. Oil outlet 807 protrudes, allowing lubricating oil to be present on both sides of the outer wall of the guide rail body for self-lubrication. The contact roller 801 facilitates rotation, disengaging from the through hole 804 and allowing the slider 4 to continue moving. The sliding plate 805 loses pressure and is reset by the second spring 808. When the sliding plate 805 moves, it slides stably in the limiting groove 1001 and vertical groove 1002 via the limiting block 9 to prevent deviation. When excess lubricating oil is squeezed out, it enters the vertical groove 1002. The displacement of the limiting block 9 generates pressure, which enters the horizontal groove 1003 and flows out of the lubrication cavity 803 via the conveying groove 1004, adhering to the guide rail body to further improve the self-lubrication effect.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
