Description

Technical Field

[0001] This utility model relates to the field of tire repair technology, specifically a tire repair fixing device. Background Technology

[0002] Tires are circular, elastic rubber products installed at the bottom of vehicles. They support the vehicle body, cushion external impacts, and ensure vehicle performance. Tires can be classified into different types according to their uses and functions. Among them, the announcement number CN 218225837 U specifically describes a self-healing tire processing, fixing, and grinding device. It includes a fixing frame, with a lifting frame fixedly installed on the top rear side of the fixing frame. The lifting frame contains a lifting mechanism, which includes a lifting screw and a lifting slider. A threaded through hole is opened at the top center of the lifting slider. The first support sleeve and the first support rod are connected by bearings, allowing the first support rod to rotate. When the second support sleeve is not in contact with the tire, the first support sleeve supports the tire and can simultaneously rotate the tire to achieve position adjustment. The pressure of the second support sleeve on the tire is removed by pulling the control handle to overcome the elastic force of the spring. The operation is simple and quick, increasing the efficiency of the device in clamping and adjusting the tire, and enhancing the device's practicality.

[0003] The above solution utilizes the cooperation between the fixing components and the auxiliary frame to clamp the inner ring of the tire and achieve the locking and fixing of the tire. However, tire repair generally requires inspection of the inner wall of the tire, so the fixing method described above has limitations. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a tire repair and fixing device that has the advantage of being able to fix and grind the inner and outer rings of the tire separately, thus avoiding the limitations of only fixing the inner cavity of the tire.

[0008] According to some embodiments, a third servo motor is fixedly connected to the top of the base plate, and a threaded post is fixedly connected to the output end of the third servo motor. The threaded post is located in the inner cavity of the connecting frame and is threadedly connected to the mounting frame. The side walls of the top plate and the fixed plate are both set to be arc-shaped.

[0009] According to some embodiments, the grinding assembly includes a connecting plate, which is fixedly installed on the top of the connecting frame.

A first bidirectional threaded rod 205 is fixedly connected to the output end of the second servo motor 204. A first connecting block 206 is threadedly connected to both side walls of the first bidirectional threaded rod 205. A top plate 207 is fixedly connected to the outer wall of the first connecting block 206. A fixing plate 208 is fixedly connected to the inner wall of the first connecting block 206.

[0023] A third servo motor 209 is fixedly connected to the top of the base plate 1. A threaded post 210 is fixedly connected to the output end of the third servo motor 209. The threaded post 210 is located in the inner cavity of the connecting frame 101 and is threadedly connected to the mounting frame 201.

[0024] Both the top plate 207 and the fixed plate 208 have curved sidewalls;

[0025] It should be noted that: the second servo motor 204 drives the first bidirectional threaded rod 205 to rotate. The threaded connection between the first bidirectional threaded rod 205 and the first connecting block 206 allows the first connecting block 206 to move simultaneously towards the middle or both ends of the fixing frame 203, which is convenient for fixing tires of different sizes. The top plate 207 can hold the inner wall of the tire, and the fixing plate 208 can clamp the outer wall of the tire, thereby fixing the tire. The third servo motor 209 drives the threaded column 210 to rotate. Since the threaded column 210 is threadedly connected to the mounting frame 201, the mounting frame 201 can move the tire up and down, which is convenient for adjusting its height. The first servo motor 202 can drive the fixing frame 203 to rotate through the first rotating shaft, thereby rotating the tire fixed by the top plate 207 or the fixing plate 208, which is convenient for the grinding component 3 to grind the damaged areas.

[0026] Reference Figures 1-4 The grinding assembly 3 includes a connecting plate 301, which is fixedly installed on the top of the connecting frame 101, and a sleeve 302 is fixedly connected to the side wall of the connecting plate 301.

[0027] A sliding column 303 is slidably connected to the inner wall of the sleeve 302, and an L-shaped column 304 is rotatably connected to the top of the sliding column 303.

[0028] An installation plate 305 is fixedly connected to the end of the L-shaped column 304. A fourth servo motor 306 is fixedly connected to the side wall of the installation plate 305. A second rotating shaft is fixedly connected to the output end of the fourth servo motor 306. A grinding wheel 307 is snapped into the end of the second rotating shaft.

[0029] It should be noted that: by driving the fourth servo motor 306, the fourth servo motor 306 drives the grinding wheel 307 to rotate through the second rotating shaft. The rotating grinding wheel 307 can grind the tire. The position of the grinding wheel 307 can be adjusted by sliding the sliding column 303 on the inner wall of the sleeve 302, and the angle of the grinding wheel 307 can be adjusted by rotating the L-shaped column 304. Both the outer and inner sides of the tire can be ground, which is simple and convenient.

[0031] The top of the second connecting block 401 is fixedly connected to a clamping plate 402, and the clamping plate 402 is set in an arc shape. The end of the sliding column 303 is threadedly connected to a threaded bolt 403, which is used to fix the L-shaped column 304.

[0032] It should be noted that by rotating the second bidirectional threaded rod 4 and utilizing the threaded connection between the second bidirectional threaded rod 4 and the second connecting block 401, the distance between the clamping plates 402 can be adjusted, which facilitates the positioning of tires of different diameters and makes it easier for the subsequent positioning assembly 2 to fix them.

[0033] Operation method: Rotate the second bidirectional threaded rod 4. Utilize the threaded connection between the second bidirectional threaded rod 4 and the second connecting block 401 to adjust the spacing between the clamping plates 402, facilitating the positioning of tires of different diameters. Drive the second servo motor 204 to rotate the first bidirectional threaded rod 205. Utilize the threaded connection between the first bidirectional threaded rod 205 and the first connecting block 206 to move the first connecting block 206 simultaneously towards the middle or both ends of the fixing frame 203, facilitating the fixing of tires of different sizes. The top plate 207 can hold the inner wall of the tire, and the fixing plate 208 can clamp the outer wall of the tire, thereby fixing the tire. Utilize the third servo motor 209 to rotate the threaded column 210. Since the threaded column 210 is threadedly connected to the mounting frame 201, the mounting frame 201 can move the tire up and down, facilitating height adjustment. The first servo motor 202 can drive the fixing frame 203 to rotate through the first rotating shaft, thereby rotating the tire fixed by the top plate 207 or the fixing plate 208 and adjusting the tire position.

[0034] By driving the fourth servo motor 306, the fourth servo motor 306 drives the grinding wheel 307 to rotate through the second rotating shaft. The rotating grinding wheel 307 can grind the tire.
