[0001] This application relates to the technical field of automobile tire leak detection devices, and in particular to a leak detection device for automobile tire production. Background Technology

[0002] After automobile tires are manufactured, in order to ensure the quality control of the products, it is necessary to test the air tightness of the tires through testing equipment to avoid the tires leaking air after leaving the factory.

[0031] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0032] This application discloses a leak detection device for automobile tire production. For example... Figure 1 As shown, the device includes a rectangular frame 10 and a tire body 13. The rectangular frame 10 is fixedly installed on the ground, and the tire body 13 is located in the middle of the cavity of the rectangular frame 10. A limiting component for clamping the tire body 13 is provided in the cavity of the rectangular frame 10. The limiting component includes a first limiting unit 14 and a second limiting unit 18. A water tank 11 and a first hydraulic cylinder 12 are also provided at the bottom of the cavity of the rectangular frame 10.

The tire body 13 is located between the first clamping plate 21 and the second clamping plate. An air intake component is provided on one side of the first limiting unit 14. The air intake component includes an air pipe 15 and a valve 17. A second hydraulic cylinder 16 is provided on one side of the second limiting unit 18. A rotating component is also provided between the first limiting unit 14 and the rectangular frame 10. The rotating component includes a flywheel ring gear 25 and a gear 26.

[0033] By setting a first limiting unit 14 and a second limiting unit 18 in the cavity of the rectangular frame 10, and cooperating with the second hydraulic cylinder 16, the tire body 13 is clamped between the first limiting unit 14 and the second limiting unit 18. An air pump is also set on one side of the rectangular frame 10. The air pump, together with the air intake assembly, sends air into the cavity of the tire body 13 through the air pipe 15. When the first hydraulic cylinder 12 is working, it lifts the water tank 11 upward, and the bottom of the outer wall of the tire body 13 is immersed in the cavity of the water tank 11. By setting a rotating assembly to drive the first limiting unit 14, the second limiting unit 18 and the tire body 13 to rotate as a whole, the air tightness of the tire body 13 is detected. This device is simple to operate and highly practical.

[0034] Please see Figure 2 The first hydraulic cylinder 12 is fixedly installed at the bottom of the cavity of the rectangular frame 10. The telescopic end of the first hydraulic cylinder 12 is fixedly connected to the water tank 11. The water tank 11 is filled with water and is located below the tire body 13.

[0035] The first hydraulic cylinder 12 is fixedly installed at the bottom of the cavity of the rectangular frame 10. The telescopic end of the first hydraulic cylinder 12 is fixedly connected to the water tank 11. The water tank 11 is filled with water. When the first hydraulic cylinder 12 works, it lifts the water tank 11 upward, and the bottom of the outer wall of the tire body 13 is immersed in the water tank 11.

[0036] Please see Figure 3 A cylindrical tube 19 is fixedly installed on the inner wall of one side of the rectangular frame 10. The end of the cylindrical tube 19 away from the rectangular frame 10 is movably connected to the first clamping plate 21 through a sealed bearing. The first hanging ring 22 is fixedly installed on the end of the first clamping plate 21 away from the cylindrical tube 19. The second hydraulic cylinder 16 is fixedly installed on the outer wall of one side of the rectangular frame 10. The telescopic end of the second hydraulic cylinder 16 movably passes through the rectangular frame 10 and is movably connected to the second clamping plate through a bearing. The second hanging ring is fixedly installed on the side of the second clamping plate away from the second hydraulic cylinder 16.

[0037] One end of the cylindrical tube 19 is fixedly installed inside the cavity of the rectangular frame 10, and the other end of the cylindrical tube 19 is movably connected to the first clamping plate 21. The second hydraulic cylinder 16 is fixedly installed on one side of the outer wall of the rectangular frame 10. The telescopic end of the second hydraulic cylinder 16 moves through the rectangular frame 10 and is movably connected to the second clamping plate through a bearing. Thus, after the tire body 13 is clamped, the tire body 13, the first clamping plate 21 and the second clamping plate can rotate synchronously.

[0038] Please see Figure 4A circular hole 23 is provided through the center of the first clamping plate 21. The air pipe 15 is fixedly inserted through the rectangular frame 10 and the cylindrical pipe 19 and communicates with the circular hole 23. The valve 17 is fixedly installed on the outer wall of the air pipe 15. The rotating assembly also includes a servo motor 20 fixedly installed on the inner wall of the rectangular frame 10. The output shaft of the servo motor 20 is fixedly connected to the rotating shaft 27.

[0039] By opening a circular hole 23 through the center of the first clamping plate 21, the air pipe 15 is fixedly inserted through the rectangular frame 10 and the cylindrical tube 19 and communicates with the circular hole 23, and the air pipe 15 is used to inflate the cavity of the tire body 13.

[0040] Please see Figure 5 The flywheel ring gear 25 is fixedly installed on the outer wall of the first clamping plate 21. The end of the rotating shaft 27 away from the servo motor 20 is fixedly connected to the gear 26. The gear 26 is movably meshed with the flywheel ring gear 25. A protective ring 24 is also fixedly installed on the outer wall of the first clamping plate 21. The protective ring 24 is located outside the flywheel ring gear 25 and the gear 26.

[0041] When the tire body 13 is rotated, the servo motor 20 drives the rotating shaft 27 to rotate. The rotating shaft 27 is fixedly connected to the gear 26. The flywheel ring gear 25 is fixedly installed on the outer wall of the first clamping plate 21. The gear 26 and the flywheel ring gear 25 are movably meshed. Thus, the rotation of the gear 26 drives the flywheel ring gear 25, the first clamping plate 21, the tire body 13 and the second clamping plate to rotate synchronously. The outer wall of the tire body 13 rotates in the cavity of the water tank 11 to detect whether there is any air leakage.

[0042] The implementation principle of the leak detection device for automobile tire production according to this application embodiment is as follows: A first limiting unit 14 and a second limiting unit 18 are set within the cavity of a rectangular frame 10. A second hydraulic cylinder 16, in conjunction with these, clamps the tire body 13 between the first limiting unit 14 and the second limiting unit 18. An air pump is also provided on one side of the rectangular frame 10. The air pump, in conjunction with an air intake assembly, delivers air into the cavity of the tire body 13 through an air pipe 15. When the first hydraulic cylinder 12 is working, it lifts the water tank 11 upwards, thus lowering the outer wall surface of the tire body 13. The end is immersed in the water tank 11 cavity. When the tire body 13 is rotated, the servo motor 20 drives the rotating shaft 27 to rotate. The rotating shaft 27 is fixedly connected to the gear 26. The flywheel gear ring 25 is fixedly installed on the outer wall of the first clamping plate 21. The gear 26 and the flywheel gear ring 25 are movably meshed. Thus, the rotation of the gear 26 drives the flywheel gear ring 25, the first clamping plate 21, the tire body 13 and the second clamping plate to rotate synchronously. The outer wall of the tire body 13 rotates in the water tank 11 cavity to detect whether there is any air leakage. This device is simple to operate and highly practical.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
