Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0022] As Figures 1-4 shown, the present utility model provides a technical solution: a wheel positioning device for wheel detection, including a base 1. Two rollers 2 are movably connected to the top of the base 1. The two rollers 2 are arranged left and right. A vertical plate 10 is fixedly connected to the rear side of the base 1. Diagonal braces 11 are fixedly connected between the left and right sides of the vertical plate 10 and the bottom plate. And a support rod 8 is movably connected to the front side of the vertical plate 10. The two rollers 2 and the support rod 8 are distributed in an equilateral triangle. Two clamping plates 9 are arranged on the support rod 8 in a front and rear distribution, and the two clamping plates 9 are locked on the support rod 8. A groove is opened on the base 1. A first motor 18 is fixedly connected in the groove, and a roller 3 is fixedly connected to the output end of the first motor 18. The groove is located between the two rollers 2.

[0023] According to the overall structure of the device, during use, loosen the clamping plate 9, place the wheel on the two rollers 2, and make the bottom of the wheel fit with the roller 3, so that the support rod 8 passes through the center of the wheel hub, and make the two clamping plates 9 distributed on the front and rear sides of the wheel, and tighten the two clamping plates 9 to clamp and fix the wheel, so as to position the wheel, prevent the wheel from rotating, facilitate the detection, and the clamping plate 9 can be loosened, start the first motor 18, the first motor 18 drives the roller 3 to rotate, and drives the wheel to rotate through friction, so as to facilitate the selection of different detection points.

[0024] AsFigure 3 As shown, on both sides of the top of the base 1 located on the left and right sides of the groove, there are sliding connections with moving seats 4. Two rollers 2 are respectively movably connected to the tops of the two moving seats 4. A motor is fixedly connected to the top of the base 1, and the output end of the motor is in transmission connection with the moving seat 4. Threaded holes are opened on both moving seats 4, and first screws 7 are threadedly connected in the threaded holes. The thread directions of the two first screws 7 are opposite, and the two first screws 7 are fixedly connected between them and fixedly connected to the output end of the second motor 6.

[0025] By driving the two first screws 7 to rotate through the second motor 6, and making the two moving seats 4 move away from each other or move relatively through the two screws with opposite thread directions, the distance between the rollers 2 can be adjusted.

[0026] As Figure 4 shown, a chute is opened on the front side of the vertical plate 10. A second screw 12 is movably connected in the chute. A movable block 15 is threadedly connected to the second screw 12, and the movable block 15 is fixedly connected to the movable plate 16. A support rod 8 is fixedly connected to the movable plate 16. A gear column 17 is provided near the bottom in the chute. The bottom end of the second screw 12 penetrates through the gear column 17. A rack 14 is fixedly connected to the right moving seat 4, and the rack 14 meshes with the gear column 17.

[0027] Through the transmission of the gear column 17 and the rack 14, when the moving seat 4 moves, it drives the second screw 12 to rotate, so that the movable block 15 moves up and down, and drives the support rod 8 to move up and down, thereby adjusting the height of the support rod 8. Cooperating with the adjustment of the distance between the rollers 2, it is convenient for wheels of different sizes to be applicable. At the same time, through the transmission of the gear column 17 and the rack 14, the support rod 8 and the rollers 2 move synchronously, making the adjustment of the applicable size of the device more convenient.

[0028] As Figure 2 shown, cylinders 13 are provided on both the left and right sides of the vertical plate 10. The two cylinders 13 are fixedly connected to the rear side of the movable plate 16. The telescopic ends of the two cylinders 13 are fixedly connected with support plates, and the support plates are in close contact with the vertical plate 10.

[0029] By extending the cylinders 13 on both sides, the fixing plates are closely attached to both sides of the vertical plate 10, thereby fixing the movable plate 16 and the support rod 8, improving the support strength of the support rod 8 and reducing the load on the support rod 8.

[0030] As Figure 3 、 4 shown, two front and rear distributed slide rails 5 are fixedly connected to the top of the base 1. The moving seat 4 is slidably connected to the slide rails 5. The rear clamping plate 9 is fixedly connected to the support rod 8. A through hole is opened on the front clamping plate 9. The support rod 8 passes through the through hole, and a circular ring 19 is threadedly connected to the end of the support rod 8. External threads are opened at the end of the support rod 8, and internal threads matching the external threads are opened in the circular ring 19.

[0031] The moving seat 4 is supported by the slide rail 5, facilitating the smooth movement of the moving seat 4. The front splint 9 can be removed through the perforation, facilitating the placement and removal of the wheel. By turning the ring 19, the threaded connection between the ring 19 and the support rod 8 causes the ring 19 to move inward, pushing the splint 9 against the wheel, thereby clamping the wheel and fastening it.

[0032] Working principle: When in use, connect the device to an external power supply. Rotate the ring 19 to loosen the splint 9, remove the front splint 9, place the wheel on the two rollers 2, and ensure that the bottom of the wheel is in contact with the roller 3. Pass the support rod 8 through the center of the wheel hub, and install the front splint 9. Turn the ring 19 to fasten the two splints 9 to clamp and fix the wheel, thereby positioning the wheel to prevent it from rotating, facilitating the detection process. Also, the ring 19 can be rotated to loosen the splint 9, and the first motor 18 is started. The first motor 18 drives the roller 3 to rotate, driving the wheel to rotate through friction, facilitating the selection of different detection points. When detecting wheels of different sizes, start the second motor 6. The second motor 6 drives the first screw rod 7 to rotate, adjusting the distance between the two rollers 2, and drives the second screw rod 12 to rotate through the gear column 17 and the rack 14, adjusting the height of the support rod 8, so that the device can meet the use of wheels of different sizes.
