Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a device for detecting the surface wear of motor vehicle tires. Background Technology

[0002] Tires are circular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. They are usually mounted on metal rims, support the vehicle body, buffer external impacts, make contact with the road surface, and ensure the vehicle's driving performance.

[0003] Chinese utility model patent CN219573819U discloses a device for detecting tire wear. This device uses an air pump to suction dust and impurities adhering to the tire's outer surface, removing these impurities and improving the accuracy of subsequent inspections. However, this device has certain drawbacks in practical use. For example, it does not limit the rotation of the tire, causing the tire to shift or wobble and failing to maintain a stable rotation. Furthermore, relying solely on the air pump suction method cannot effectively remove some impurities stuck in the tire's gaps. Both of these issues affect the accuracy of subsequent inspections. Therefore, this paper proposes a device for detecting the surface wear of motor vehicle tires to address these problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, the rotation of the threaded rod drives multiple sets of fixed blocks to simultaneously abut against the inner wall of the tire, ensuring that the tire remains stable and centered during rotation and preventing displacement or shaking caused by centrifugal force or external force. In conjunction with the cleaning brush, stubborn impurities in the tire crevices can be removed, preventing them from affecting the accuracy of subsequent inspections.

Multiple sets of through holes are opened on the outer wall of the connecting plate, all communicating with the air pump's air inlet. A base is rotatably connected to the upper end of the workbench. The testing instrument is installed at the edge of the workbench's end face. A sliding groove is opened on the upper end of the workbench, and a slider is slidably connected within the groove. Two sets of sliding rods are slidably connected to the outer wall of the slider, and a cleaning brush is connected to the ends of both sets of sliding rods. Multiple sets of side plates are fixedly connected to the circumference of the base's end face. Connecting rods are slidably connected to the outer walls of the multiple sets of side plates, and fixed blocks are fixedly connected to the ends of the connecting rods. A threaded rod is rotatably connected to the base's end face, and a sliding mechanism that synchronously drives multiple sets of fixed blocks is installed on the outer wall of the threaded rod.

[0008] Preferably, the sliding mechanism includes a slide block threadedly connected to a threaded section of a threaded rod. The outer wall of the slide block is rotatably connected to multiple sets of connecting rods, and the number of connecting rods is the same as the number of connecting rods. The positions of the multiple sets of connecting rods correspond one-to-one with the positions of the multiple sets of connecting rods, and their ends are rotatably connected to the corresponding connecting rods.

[0009] Preferably, the inner wall of the chute is rotatably connected to a threaded rod II, and the slider is threadedly connected to the threaded section of the threaded rod II.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a device for detecting the surface wear of motor vehicle tires, which has the following beneficial effects:

[0015] 1. This utility model uses the rotation of the threaded rod to drive multiple sets of fixed blocks to synchronously abut against the inner wall of the tire, ensuring that the tire remains stable and centered during rotation, avoiding deviation or shaking caused by centrifugal force or external force. With the cleaning brush, it can remove stubborn impurities in the tire crevices, providing a reliable rotational basis for subsequent testing and improving the accuracy of the data collected by the testing instrument.

[0016] 2. This utility model avoids the limitations of traditional single air pump adsorption by using a coordinated design of air pump and cleaning brush. The air pump removes surface dust and loose impurities, while the cleaning brush adapts to the tire surface through the elastic force of the spring. The cleaning brush automatically feeds when it encounters the concave area of ​​the tire and automatically moves outward when it encounters the convex area, ensuring the uniformity of cleaning force and avoiding damage to the tire due to excessive pressure or incomplete cleaning due to insufficient pressure.

[0022] This utility model provides a technical solution:

[0023] Reference Figure 1-3 A vehicle tire surface wear detection device includes a workbench 1 and a detector 5. An air pump 3 and a connecting plate 2 are fixedly connected to the upper end of the workbench 1. Multiple sets of through holes are opened on the outer wall of the connecting plate 2, and all of them are connected to the air inlet of the air pump 3. A base 4 is rotatably connected to the upper end of the workbench 1. The detector 5 is installed at the edge of the end face of the workbench 1. A slide groove 13 is opened at the upper end of the workbench 1. A slider 16 is slidably connected in the slide groove 13. Two sets of slide rods 17 are slidably connected to the outer wall of the slider 16. The ends of the two sets of slide rods 17 are connected to a cleaning brush 18. Multiple sets of side plates 6 are fixedly connected to the circumference of the end face of the base 4. A connecting rod 7 is slidably connected to the outer wall of the multiple sets of side plates 6, and a fixing block 8 is fixedly connected to the end of the connecting rod 7. A threaded rod 9 is rotatably connected to the end face of the base 4. A sliding mechanism that synchronously drives the multiple sets of fixing blocks 8 to slide is installed on the outer wall of the threaded rod 9.

[0024] Furthermore, by rotating the threaded rod 9, multiple sets of fixing blocks 8 can be simultaneously controlled to move towards the inner wall of the tire, ensuring that the tire remains stably centered during rotation and preventing deviation or wobbling. Simultaneously, the movement of the sliding rod 17 during tire rotation ensures that the cleaning brush 18 remains in contact with the tire surface gaps. It should be noted that the connection method, installation means, and technical functions of the detector 5 are all mature technologies and are irrelevant to the design purpose of this solution; therefore, they will not be described in detail.

[0025] The sliding mechanism includes a slide block 21 threadedly connected to the threaded section of the threaded rod 9. Multiple sets of connecting rods 12 are rotatably connected to the outer wall of the slide block 21, and the number is the same as the number of multiple sets of connecting rods 7. The positions of the multiple sets of connecting rods 12 correspond one-to-one with the positions of the multiple sets of connecting rods 7, and the ends are rotatably connected to the corresponding connecting rods 7.

[0026] Furthermore, the rotational connection between the slide block 21 and the connecting rod 12 converts the rotational motion of the threaded rod 9 into the linear movement of multiple sets of connecting rods 7, thereby achieving synchronous and symmetrical clamping of the fixed block 8.

[0027] The inner wall of the slide 13 is rotatably connected to a threaded rod 14, and the slider 16 is threadedly connected to the threaded section of the threaded rod 14.

[0028] Furthermore, the movement of the cleaning brush 18 along the groove 13 can be precisely controlled by rotating the threaded rod 14, thus allowing for flexible adjustment according to the tire size.

[0029] A limiting rod 10 is fixedly connected to the end face of the base 4. The slide block 21 is slidably connected to the outer wall of the limiting rod 10. A rotating block 11 is fixedly connected to the end of the threaded rod 9. The ends of the two sets of slide rods 17 are fixedly connected to the limiting blocks 19, and the radius of the limiting blocks 19 is larger than that of the slide rods 17. A spring 20 is sleeved on the outer wall of the slide rods 17. The two ends of the spring 20 are fixedly connected to the limiting blocks 19 and the slider 16 respectively. The outer walls on both sides of the slider 16 are in contact with the inner wall of the slide groove 13.

[0030] Specifically, the elastic design of the spring 20 enables the slide bar 17 to have adaptive adjustment capabilities. When there are uneven surfaces on the tire, the cleaning brush 18 can float up and down with the tire contour to maintain a constant contact pressure, avoiding damage to the tire due to excessive pressure or incomplete cleaning due to insufficient pressure.

[0031] The worktable 1 is rotatably connected to a rotating rod 15, which is coaxially and fixedly connected to the threaded rod 14. The bottom surface of the worktable 1 is fixedly connected to a drive motor, and the output shaft is coaxially and fixedly connected to the base 4.

[0032] In practical use, the working principle of this utility model is as follows:

[0033] The operator first places the tire on the base 4 and manually controls the threaded rod 9 to rotate through the rotating block 11. The threaded rod 9 drives the slide 21 to move axially along the limit rod 10. The slide 21 pushes the connecting rod 7 to slide towards the edge of the tire through multiple sets of connecting rods 12, so that the fixing block 8 simultaneously abuts against the inner wall of the tire, ensuring that the tire is stably centered during rotation and avoiding deviation or shaking caused by centrifugal force or external force, thus providing a stable rotational foundation for subsequent testing.

[0034] After the tire is secured, the operator starts the drive motor, which drives the base 4 to rotate the tire at a constant speed. Simultaneously, the air pump 3 on the workbench 1 uses negative pressure to adsorb dust and loose impurities from the tire surface through the through-hole of the connecting plate 2. At the same time, the operator rotates the threaded rod 14 via the rotating rod 15, driving the slider 16 to move horizontally along the groove 13, causing the cleaning brush 18 to adhere to the tire's outer wall. With the elastic force of the spring 20, the tire continues to rotate during the cleaning process, and the cleaning brush 18 gradually covers the tire surface as the slider 16 moves. It automatically feeds into concave areas and moves outwards from convex areas to ensure uniform cleaning force. After cleaning, the air pump 3 stops working, and the detector 5 starts to perform high-precision detection of the tire surface wear.

[0035] After the inspection is completed, rotate the threaded rod 9 in the opposite direction to release the clamping block 8 on the tire, and the operator can easily remove the tire.

[0036] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
