Description

Technical Field

[0001] This utility model relates to the field of tire retreading technology, and in particular to an adjustable tire retreading clamping device. Background Technology

[0002] Tire retreading is the process of repairing and refining tires that have been worn or damaged for other reasons and lost their performance, so that they can be used again. Tires that have been retreaded are not as strong and safe as new tires. They are generally only installed on the rear tires of a vehicle alongside new tires and are not suitable for use on the front tires.

[0003] A search revealed that Chinese Patent No. CN216770932U discloses a double-sided clamping device for motorcycle tire inspection, comprising a base, a support frame A, and a support frame B. The support frame A is fixedly installed on the top of the base, and the support frame B is fixedly installed in the middle of the bottom of the support frame A. Clamping mechanisms are provided at both ends of the outer side of the support frame A, and a leakage detection mechanism is provided at the bottom of the support frame B. The clamping mechanism consists of a servo motor, an electric telescopic rod, a support plate B, a guide rod, a clamping plate, a tire, and an air inlet.

[0004] In actual use, this patent has the following drawbacks:

[0005] During the process of clamping the tire with the double-sided clamping device, an electric telescopic rod is used to drive the clamping plate to clamp the tire on both sides. Different tires have different sizes for different purposes. If the clamping distance of the electric telescopic rod to the tire is too long, the tire may be damaged. If the clamping distance of the electric telescopic rod to the tire is too short, the tire clamping may be unstable, thus reducing the clamping effect of the double-sided clamping device on the tire.

The adjusting gear 8 is rotatably installed in the movable frame 5. The clamping plate 9 is fixedly installed on one side of the movable plate 6.

[0028] The clamping component 3 allows workers to easily adjust the distance between the moving frame 5 and the clamping plate 9 according to actual needs, thereby preventing the clamping plate 9 from clamping the tire with too much or too little force, which could damage the tire or cause unstable clamping. This increases the retreading clamping effect of the clamping equipment.

[0029] Reference Figure 3 In this embodiment, the annular frame 10 is fixedly installed on the front side of the movable frame 5, and the rotating shaft 11 is rotatably installed on the front side of the movable frame 5.

[0030] The arc-shaped clamping plate 12 is slidably installed inside the annular frame 10, and the bidirectional threaded rod 13 is rotatably installed inside the annular frame 10. The bidirectional threaded rod 13 is threadedly connected to the arc-shaped clamping plate 12.

[0031] The arc-shaped clamping plate 12 can limit and fix the adjusting gear 8 through the rotating shaft 11, thereby improving the stability of the clamping device when clamping tires for retreading.

[0032] The first knob 14 is rotatably mounted on one side of the annular frame 10. The first knob 14 is connected to the bidirectional threaded rod 13. The second knob 15 is fixedly mounted on the front side of the rotating shaft 11. The hydraulic cylinder 26 is fixedly mounted on the top of the support plate 4. The movable frame 5 is connected to the output end of the hydraulic cylinder 26.

[0033] Reference Figure 4 In this embodiment, a linkage component 17 for synchronously adjusting the rotation angle of the gear 8 is provided on the rear side of the movable frame 5. The linkage component 17 includes a linkage frame 18, a fixing plate 19, a connecting rod 20, a first bevel gear 21, a second bevel gear 22, a first square plate 23, and a second square plate 24. The linkage frame 18 is slidably installed in the support frame 2.

[0034] The linkage component 17 enables the adjusting gear 8 to rotate synchronously, thereby improving the stability and accuracy of the moving plate 6 during movement.

[0035] The fixed plate 19 is fixedly installed between the linkage frame 18 and the movable frame 5. The connecting rod 20 is rotatably installed between the linkage frame 18 and the movable frame 5. The first bevel gear 21 is rotatably installed inside the linkage frame 18. The second bevel gear 22 is rotatably installed inside the linkage frame 18. The connecting rod 20 is connected to the first bevel gear 21 and the connecting rod 20 is connected to the adjusting gear 8.

[0036] The first square plate 23 is rotatably mounted on one side of the linkage frame 18. The first square plate 23 is connected to the second bevel gear 22. A square groove 25 is provided on one side of the first square plate 23. The second square plate 24 is slidably mounted in the square groove 25. The second square plate 24 is connected to the second bevel gear 22.

[0037] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0038] When using a clamping device to clamp a tire for retreading, first turn the second knob 15 as needed. The second knob 15 drives the adjusting gear 8 to rotate via the rotating shaft 11. The adjusting gear 8 rotates via the connecting rod 20, the first bevel gear 21, and the second bevel gear 22. The second bevel gear 22 drives another second bevel gear 22 to rotate via the first square plate 23 and the second square plate 24. This causes the connecting rod 20 to drive another adjusting gear 8 to rotate. The adjusting gear 8 drives the moving plate 6 to move via the rack 7. Move the clamping plate 9 to adjust the distance between the clamping plate 9 and the moving frame 5. After the distance between the clamping plate 9 and the moving frame 5 is adjusted, refer to the above operation. Hold the first knob 14 to move the arc-shaped clamping plate 12 through the bidirectional threaded rod 13, so that the arc-shaped clamping plate 12 clamps and limits the rotating shaft 11. Place the tire between the clamping plates 9 and start the hydraulic cylinder 26 to fully extend it. The hydraulic cylinder 26 moves the clamping plate 9 through the moving frame 5 and the moving plate 6, so that the clamping plate 9 clamps the tire.
