Description

Technical Field

[0001] The invention relates to the technical field of guide rails, and in particular to a linear guide rail with dustproof and anti-corrosion structural functions. Background Art

[0002] Linear guides, also known as linear rails, slides, linear guides, and linear slides, are used in high-precision or high-speed linear reciprocating motion situations. They can bear a certain torque and can achieve high-precision linear motion under high load conditions.

[0003] At present, when the slider moves along the slide rail, it will cause lateral deviation of one side of the linear guide rail by squeezing and the other side by stretching, resulting in over-positioning. This puts very high requirements on the mechanism and installation. If the object has a large stroke and the equipment is too heavy, the structure of the linear guide rail fixed on all sides will be too bulky and large in size. If the rigidity of the surrounding structure is poor, it will easily get stuck and cause an accident.

[0004] In order to solve the problems raised in the above-mentioned technology, for example, application number CN201921554961.1 discloses a linear guide rail with precision adjustment function, comprising a main slide rail, an outer wall at the top of the main slide rail is provided with a mounting hole, and the main slide rail is fixedly mounted on a workbench through the mounting hole and the cooperation of fixing bolts, and auxiliary guide rails fixed to the workbench are arranged on both sides of the main slide rail, and the two auxiliary guide rails have the same structure, and slide grooves are arranged on the outer walls on both sides of the main slide rail, and the slide groove structures on both sides of the main slide rail are the same, and a slider that can slide along the main slide rail is sleeved on the outside of the main slide rail through the slide groove, and the adjustment mechanism arranged at the bottom of the slider cooperates with the auxiliary guide rails on both sides of the main slide rail. When the slider moves along the slide rail, the sliding precision of the slider on the main slide rail is guaranteed, the extrusion of the main slide rail by the slider is avoided, the cooperation precision between the slider and the main slide rail is improved, and the jamming situation is not easy to occur. However, the device still has the following defects: After long-term use of this device, the surface of the guide rail is easily corroded, which aggravates the friction between the guide block and the guide rail, causing problems with the movement of the guide block, poor quality of the guide rail, and a short service life, which is not conducive to use.

[0005] In order to solve the problems raised in the above-mentioned technology, for example, application number CN202220713725.5 discloses an anti-corrosion linear guide rail, including a guide rail body, a rolling groove is arranged inside the guide rail body, a ball is slidably connected inside the rolling groove, an oil groove is arranged inside the guide rail body, oil storage cotton is placed in the oil groove, an oil filling groove is arranged inside the oil storage cotton, and a sealing ring is arranged at the right end of the oil groove. In this scheme, a ball is arranged inside the guide rail, which can reduce the friction between the guide block and the guide rail. At the same time, an oil storage cotton is arranged inside the guide rail to store lubricating oil. When the ball rotates, the surface is covered with lubricating oil to play a lubricating role, thereby making the guide block move more smoothly, and the lubricating oil has the effect of reducing the probability of corrosion of the guide rail. In addition, an anti-corrosion layer is arranged on the surface of the guide rail, which can effectively prevent corrosion on the surface of the guide rail, and has the effect of ensuring the quality of the guide rail and extending the service life of the guide rail. However, the device still has the following defects: Since linear guides are mostly used in mechanical production working environments, dust and impurities often enter the guides and sliders. After long-term use, dust is easy to accumulate, which can easily cause damage to the guides and internal wear of the sliders, thereby shortening the service life of the guides. Summary of the invention

[0006] The purpose of the present invention is to solve the problems in the prior art and to propose a linear guide rail with dust-proof and anti-corrosion structural functions, which can be dust-removed and lubricated to avoid dust accumulation and damage to the guide rail.

[0007] To achieve the above-mentioned objectives, the present invention proposes a linear guide rail with dust-proof structure and anti-corrosion structure functions, comprising a guide rail body, a slider, an extension block, a dust-proof structure, an anti-corrosion structure, a motor, a drive shaft, a turntable and bristles, the guide rail body being slidably connected with a slider, four extension blocks being integrally arranged above the slider, the four extension blocks being symmetrically distributed on both sides above the slider in groups of two, each extension block being provided with a dust-proof structure, and anti-corrosion structures being symmetrically arranged on both sides below the slider, the dust-proof structure comprising a motor, a drive shaft, a turntable and bristles, the motor being installed on the top of the extension block by bolts, the output end of the motor passing through the bottom of the extension block and being rotatably connected with a drive shaft, the end of the drive shaft being rotatably connected with a turntable, bristles being pasted under the turntable, and the bristles being in contact with the upper surface of the guide rail body.

[0017] Beneficial effects of the present invention: 1. The present invention can prevent dust accumulation through the cooperation of the dust-proof structure and the dust scraper. When the slider slides back and forth on the guide rail body, the motor is started by an external controller, the motor drives the driving shaft to rotate, the driving shaft drives the turntable to rotate, the turntable drives the brush bristles to rotate, and then the dust on the upper surface of the guide rail body is cleaned, and the accumulation of dust and impurities on the guide rail body is avoided. At the same time, the dust scraper on the slider can scrape the dust with the movement of the slider, and scrape the dust into the dust collecting groove, so as to further clean the dust and impurities, and the sticky dust stickers on both sides of the fixed block can adhere to the dust on both sides of the guide rail body, so as to perform all-round dust removal, thereby achieving the effect of dust prevention, extending the service life of the guide rail, and solving the problem that dust is easy to accumulate after long-term use, which easily causes damage to the guide rail and wear inside the slider, thereby shortening the service life of the guide rail. 2. The present invention can lubricate the inside of the guide rail and the slider by cooperating with the anti-corrosion structure and the oil filling hole. By pouring the lubricating oil into the oil filling hole, the lubricating oil can flow into the oil filling channel through the oil filling hole, and flow from the oil filling channel to the inside of the guide rail and the slider. At the same time, as the slider slides back and forth on the guide rail body, the scraper on the fixed block can scrape the lubricating oil, thereby ensuring that the lubricating oil can be evenly applied to the inside of the guide rail and the slider, avoiding corrosion of the structure after long-term use, and further extending the service life of the guide rail.
