Description

Technical Field

[0001] This utility model relates to the field of rust removal machine technology, and more specifically, to a rust removal wheel fixing structure that helps extend service life. Background Technology

[0002] Because the rust removal wheels of rust removal machines need to move up and down frequently during operation, the existing rust removal wheels on rust removal machines are fixed in a way that involves creating a groove on the machine body, installing a slider in the groove, fixing the wheel axle seat to the slider, and then rotating the wheel axle of the rust removal wheel onto the wheel axle seat. This structure results in poor slider clearance during use, which leads to increased clearance due to wear during up-and-down movement. This causes the rust removal wheel to wobble more during operation, easily damages the bearings, and makes it difficult to replace worn sliders. Therefore, the existing rust removal wheel fixing structure needs to be improved. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a rust removal wheel fixing structure that helps to extend the service life, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rust-removing wheel fixing structure that helps extend service life, comprising a wheel axle seat, a linear guide rail respectively provided on both sides of the wheel axle seat, a slider of the linear guide rail being fixedly connected to the wheel axle seat, a fixing seat fixed at both ends of the linear guide rail, the fixing seat being used to fix it to the body of the rust removal machine, and a dust cover being fitted on the guide rail body on both the upper and lower sides of the slider of each linear guide rail; an air blowing module is installed on both the upper and lower sides of the wheel axle seat, the air outlet of the air blowing module being connected to the inside of the dust cover, so that the air blowing module can blow gas into the dust cover.

[0005] As a preferred technical solution of this utility model, the air blowing module includes a cylinder, a piston, an air inlet pipe, and an air outlet pipe. A cylinder is respectively provided on the upper and lower sides of the wheel axle seat. The cylinders are all fixed on the wheel axle seat and are correspondingly arranged with the wheel axle of the rust removal wheel. The outer ends of the cylinders are all sealed. A piston is coaxially telescopically installed inside the cylinder. The piston is connected to the wheel axle of the rust removal wheel through a transmission mechanism. The cylinder is provided with an air inlet pipe and an air outlet pipe. The air outlet pipe is connected to the inside of the corrugated dust cover through a flexible hose. A check valve is built into both the air inlet pipe and the air outlet pipe.

[0006] As a preferred technical solution of this utility model, the transmission mechanism includes a magnet and several magnetic blocks. Each piston has a magnet embedded in it. A rotating cylinder is also rotatably mounted on the wheel axle seat. The rotating cylinder is coaxially arranged with the wheel axle of the rust removal wheel. Several magnetic blocks are fixed circumferentially on the outer surface of the rotating cylinder. The magnet and the magnetic blocks attract each other.

[0007] As a preferred embodiment of this utility model, a rubber sleeve is coaxially fixed inside the rotating drum.

[0008] As a preferred embodiment of this invention, the magnet is elongated.

[0009] As a preferred embodiment of this utility model, a filter is installed on the air inlet of the air inlet pipe.

[0010] As a preferred embodiment of this utility model, the linear guide is an optical axis linear guide.

[0011] As a preferred embodiment of this utility model, the dust cover is a rubber corrugated dust cover tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] By changing the slider structure to a sliding structure composed of two linear guide rails, the clearance fit is better, the rust removal wheel wobbles less when working, the bearing is less likely to be damaged, the replacement frequency is reduced, the rust removal wheel wobble is reduced, and the service life is significantly increased.

[0014] By installing a dust cover on the main body of the linear guide, the impact of dust on the main body of the guide can be greatly reduced, thus reducing the wear of the linear guide.

[0015] It also features an air-blowing module. This module uses the power generated by the rotation of the rust-removing wheel axle to drive the piston in the cylinder of the air-blowing module to reciprocate, continuously introducing external air into the dust cover. This accelerates the circulation of air between the dust cover and the outside environment, allowing the heat generated on the guide rail body to dissipate to the outside in a timely manner. This prevents the guide rail from overheating due to the presence of the dust cover, thus improving the lifespan of the linear guide rail. Attached Figure Description

[0020] 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.

[0021] like Figures 1 to 3 As shown, this utility model provides a rust-removing wheel fixing structure that helps extend service life. It includes a wheel axle seat 2, with a linear guide rail 1 on each side of the wheel axle seat 2. The sliders of the linear guide rail 1 are fixedly connected to the wheel axle seat 2. A fixing seat is fixed to each end of the linear guide rail 1, and the fixing seats are used to fix it to the body of the rust-removing machine. A dust cover 4 is fitted on the upper and lower sides of the guide rail body of each linear guide rail 1 slider. An air blowing module is installed on the upper and lower sides of the wheel axle seat 2, and the air outlet of the air blowing module is connected to the inside of the dust cover 4, allowing the air blowing module to blow gas into the dust cover 4. Although the dust cover 4 is not completely sealed, it still hinders heat exchange between the guide rail body and the outside air, potentially causing the guide rail body to overheat during operation. This leads to linear expansion of the material of the linear guide rail 1, causing changes in the guide rail's dimensions. This results in geometric deviations in the guide rail, reducing its working accuracy and stability. Increased temperature also causes the lubricant in the linear guide rail 1 to thin, increasing friction between the guide rail and the slider. This reduces the smoothness of the guide rail's movement, increases power consumption, and may even cause abnormal noises; high temperatures can lead to a decrease in the guide rail's thermal conductivity. When heat cannot be dissipated in time, the guide rail temperature rises, potentially causing problems such as thermal expansion, deformation, and lubricant failure. Under high-temperature environments, the hardness and wear resistance of the guide rail material may decrease, leading to accelerated wear on the guide rail surface and consequently affecting its service life. To address this, an air-blowing module is installed. This module blows air into the dust cover 4, and the blown air is discharged through the gaps at both ends of the dust cover 4, thereby accelerating heat exchange between the guide rail body and the outside air, achieving cooling of the guide rail body. The linear guide rail 1 is an optical axis linear guide rail 1. The dust cover 4 is a rubber corrugated dustproof tube.

[0022] The air blowing module includes a cylinder 5, a piston 6, an inlet pipe 9, and an outlet pipe 10. A cylinder 5 is located on each of the upper and lower sides of the axle seat 2, and both cylinders 5 are fixed to the axle seat 2. The cylinders 5 correspond to the axle of the rust-removing wheel, and their outer ends are sealed. A piston 6 is coaxially and telescopically mounted inside the cylinder 5, and the piston 6 is connected to the axle of the rust-removing wheel via a transmission mechanism. The cylinder 5 is equipped with the inlet pipe 9 and the outlet pipe 10. The outlet pipe 10 is connected to the inside of the corrugated dust cover 4 via a flexible hose 11. Both the inlet pipe 9 and the outlet pipe 10 have built-in check valves. The check valve in the outlet pipe 10 prevents gas from entering the cylinder 5 from the dust cover 4, and the check valve in the inlet pipe 9 prevents gas from flowing out of the cylinder 5 through the dust cover. A filter is installed at the inlet of the inlet pipe 9 to prevent external dust from being sucked into the cylinder 5.

[0023] The transmission mechanism includes a magnet 7 and several magnetic blocks 8. Each piston 6 has a magnet 7 embedded in it. A rotating cylinder 3 is rotatably mounted on the axle seat 2. The rotating cylinder 3 is coaxially arranged with the axle of the rust-removing wheel. Several magnetic blocks 8 are fixed circumferentially on the outer surface of the rotating cylinder 3, and the magnet 7 and magnetic blocks 8 attract each other. In use, after the rust-removing wheel spindle is mounted on the axle seat 2, the rotating cylinder 3 is tightly fitted onto the spindle. When the spindle rotates, it also drives the rotating cylinder 3 to rotate. The rotating cylinder 3 causes the multiple magnetic blocks 8 and two magnet 8 to intermittently interact magnetically, allowing each piston 6 to reciprocate under the drive of the magnet 8. This continuously draws in external gas through the air inlet pipe 9 and discharges it into the dust cover 4 through the air outlet pipe 10. A rubber sleeve is coaxially fixed inside the rotating cylinder 3. The rubber sleeve increases the friction between the rotating cylinder 3 and the rust-removing wheel spindle, allowing the spindle to drive the rotating cylinder 3 to rotate. The magnet 7 is elongated.

[0024] In use, the axle of the rust-removing wheel is installed in the axle seat 2. Because the slider structure is changed to a sliding structure composed of two linear guides 1, the clearance fit is better, the rust-removing wheel wobbles less during operation, the bearings are less prone to damage, reducing replacement frequency, and the rust-removing wheel wobble is reduced, significantly extending its lifespan. Furthermore, by installing a dust cover 4 on the main body of the linear guide 1, the impact of dust on the guide body is greatly reduced, decreasing wear on the linear guide 1. Additionally, an air-blowing module is included. This module utilizes the power generated by the rotation of the rust-removing wheel axle to drive the piston 6 in the cylinder 5 of the air-blowing module to reciprocate via magnetic transmission, continuously introducing external gas into the dust cover 4. This accelerates the circulation of gas within the dust cover 4 with the outside environment, allowing the heat generated on the guide body to dissipate to the outside in a timely manner, preventing the guide body from overheating due to the presence of the dust cover 4, and further extending the lifespan of the linear guide 1.
