Description

Technical Field

[0001] This utility model relates to the technical field of tire testing equipment, specifically a vehicle tire testing and fixing device. Background Technology

[0002] Car tires are one of the most important components of a car. They come into direct contact with the road surface and, together with the car's suspension, mitigate the impacts the car experiences while driving, ensuring good ride comfort and smooth driving; ensuring good adhesion between the wheels and the road surface; improving the car's traction, braking, and passability; and bearing the weight of the car. The important role of tires in automobiles is increasingly recognized. During car tire testing, it is usually necessary to fix the car tires on a testing platform.

[0003] A search revealed Chinese patent publication number CN211292019U, which discloses a fixing device for automobile tire testing. This patent effectively solves the problem of difficulty in fixing automobile tires during testing, and achieves the technical effect of adjusting different engagement diameters according to different tire diameters. In addition, the tool is easy to take out during the testing process, saving the time of staff to go back and forth to retrieve the tool.

[0004] However, most common car tire testing devices currently require the tire to be placed on a testing platform for testing. However, since the bottom of the tire is in close contact with the testing platform, it is not convenient to test both the top and bottom surfaces of the tire. The tire needs to be flipped over before testing, which is a rather cumbersome operation. Utility Model Content

The output shaft of the flip motor 10 is mounted on the mounting plate 3. A rectangular through hole 4 is formed in the mounting plate 3. A transmission cavity 21 is formed inside the mounting plate 3. A first transmission slider 11 and a second transmission slider 12 are slidably mounted in the transmission cavity 21. Two first racks 18 and two second racks 19 are respectively protruding from the first transmission slider 11 and the second transmission slider 12. Two transmission gears 20 are arranged in the transmission cavity 21, and the transmission gears 20 mesh with the first racks 18 and the second racks 19 respectively. Both the first and second transmission sliders 11 and 12 extend through the transmission cavity 21 into the rectangular through hole 4. A clamping block 5 is installed at one end of each slider extending into the rectangular through hole 4. An electric telescopic rod 23 is installed on the base plate 1. A drive motor 15 is installed on the output shaft of the electric telescopic rod 23. A transmission disc 16 is installed on the output shaft of the drive motor 15.

The second transmission slider 12 is threadedly connected to the threaded rod 14 through the threaded hole 17. An arc-shaped groove 6 is opened on the clamping block 5. Multiple rotatable sliding shafts 7 are arranged at intervals along the arc-shaped groove 6.

[0025] Through the coordinated arrangement of the mounting plate 3, the first transmission slider 11, the second transmission slider 12, the clamping block 5, and the flipping motor 10, the tire can be placed between the two clamping blocks 5 during use. The servo motor 13 drives the threaded rod 14 to rotate, and through the threaded advance relationship, the transmission gear 20, the first rack 18, and the second rack 19, the first transmission slider 11 and the second transmission slider 12 can drive the two clamping blocks 5 to move closer together, clamping and fixing the tire. The sliding shaft 7 in the arc groove 6 on the clamping block 5 allows the tire to rotate while being clamped by the two clamping blocks 5. When it is necessary to inspect the bottom surface of the tire, the transmission plate 16 can be driven to descend vertically by the electric telescopic rod 23 to provide space for the tire to flip. At this time, the flipping motor 10 drives the mounting plate 3 to flip, thereby realizing the flipping of the tire bottom surface and improving the comprehensiveness of the inspection.

[0026] Specifically, in this embodiment, guide rings 8 are provided on the inner sides of both support frames 2, and two symmetrical arc-shaped guide blocks 9 are protruding from both ends of the mounting plate 3 and attached to the outer side of the guide rings 8.

[0027] By setting the guide ring 8 and the arc-shaped guide block 9, the position of the mounting plate 3 can be restricted, allowing the mounting plate 3 to rotate along the guide ring 8 via the arc-shaped guide block 9, thereby restricting the rotation path of the mounting plate 3.

[0028] Specifically, in this embodiment, the outer surfaces of multiple sliding shafts 7 are all covered with anti-slip rubber sleeves.

[0029] By setting the anti-slip rubber sleeve, the tire can easily rotate after contacting the sliding shaft 7, so that after the two clamping blocks 5 clamp and fix the tire, the clamping blocks 5 can rotate between the two clamping blocks 5.
