Description

Technical Field

[0001] This utility model relates to the field of tire puncture resistance testing technology, and more specifically, to a tire testing bench. Background Technology

[0002] Run-flat tires are designed to allow a vehicle to continue traveling at 80 kilometers per hour even if a tire leaks air while driving, preventing a blowout that could lead to loss of control and traffic accidents. During the tire manufacturing process, tires need to be tested using a puncture test device, which consists of a telescopic component and a puncture needle.

[0003] The announcement number CN219830637U proposes a puncture-proof and explosion-proof tire testing device. This device can fix the tire and perform puncture resistance testing; however, during the testing process, it can only perform puncture testing on one area of ​​the tire, resulting in insufficient test data. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose a tire testing bench.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A tire testing stand includes a testing platform, an inclined platform, a hydraulic cylinder, a translation and tilting assembly, a cylinder, a through hole, a fixing assembly, a fixing frame, a puncture assembly, and a spraying assembly.

[0007] The inclined platform, hydraulic cylinder, and fixed frame are all fixed on the test bench;

[0008] The translation and tilting assembly is fixed on the telescopic rod of the hydraulic cylinder;

[0009] The hollow cylinder is connected to a translation and flipping component, and symmetrical through holes are opened on the cylinder;

[0010] The fixing components are symmetrically fixed inside the cylinder and fit into the through hole;

[0011] Both the puncture assembly and the spray assembly are fixed on a frame to spray water onto the puncture site of the tire after puncture to check for leaks.

[0012] Furthermore, the fixing assembly includes a mounting rod, a first telescopic member, and an outer support fixing plate. The mounting rod is fixedly installed inside the cylinder, and the first telescopic member is symmetrically fixed on the mounting rod. The first telescopic member is connected to an outer support fixing plate that moves along the through hole and fits against the inner side of the tire body.

[0013] The above solution uses a fixing component to securely fix the tire carcass to the cylinder. Subsequently, the tire carcass rotates with the cylinder to perform puncture resistance performance tests on different parts of the tire carcass.

[0014] Furthermore, the translation and flipping assembly includes a fixed plate, a second telescopic component, a telescopic rod, a connecting plate, and a servo motor. The hydraulic cylinder is connected to the fixed plate, and the second telescopic component and the telescopic rod are horizontally fixed on the fixed plate. The second telescopic component and the telescopic rod are both connected to the connecting plate, and the servo motor is fixed on the connecting plate. The servo motor is connected to the cylinder.

[0015] The above solution uses a translation and flipping component in conjunction with a hydraulic cylinder, a cylinder, and a fixing component to enable the tire carcass to move automatically to a designated area for subsequent puncture resistance testing. After the test is completed, the tire can be automatically reloaded onto the test bench without manual intervention.

[0016] Furthermore, the spray assembly includes a suction pump and a spray pipe. The suction pump and the inclined spray pipe are fixed on the fixed frame. The input end of the suction pump is connected to a water source, and the output end of the suction pump is connected to one end of the spray pipe.

[0017] After the above method completes the puncture of a certain local area of ​​the tire carcass, the spraying component immediately sprays water onto the punctured area. After spraying water, the staff can visually check whether there is any air leakage.

[0018] Furthermore, a collection box is placed on the test table below the puncture assembly.

[0019] The above solution can collect the wastewater that flows down naturally during the spraying process through a collection box.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] Compared to existing technologies, this device can automatically puncture the tire carcass and spray water after puncture to check and understand its puncture resistance. At the same time, different areas of the tire carcass can be punctured during the test, thus making the test area more comprehensive. Furthermore, the raising and lowering of the tire does not require manual operation, thus significantly reducing labor intensity and making the tire carcass puncture resistance test process better.

[0029] The translation and flipping assembly 4 is fixed on the telescopic rod of the hydraulic cylinder 3;

[0030] The hollow cylinder 5 is connected to the translation and flipping component 4, and the cylinder 5 has symmetrical through holes 11.

[0031] The fixing component 6 is symmetrically fixed inside the cylinder 5 and cooperates with the through hole 11;

[0032] Both the puncture assembly 8 and the spray assembly 9 are fixed on the mounting frame 7 to spray water onto the puncture site of the tire after puncture to check for leaks.

[0033] Further refinements of the embodiments of this utility model, such as... Figure 1 As shown, the fixing component 6 includes a mounting rod 10, a first telescopic member 12, and an outer support fixing plate 13. The mounting rod 10 is fixed inside the cylinder 5. The first telescopic member 12 is symmetrically fixed on the mounting rod 10. The first telescopic member 12 is connected to the outer support fixing plate 13, which moves along the through hole 11 and fits against the inner side of the tire body.

[0034] Further refinements of the embodiments of this utility model, such as... Figure 1 and Figure 2As shown, the translation and flipping assembly 4 includes a fixed plate 14, a second telescopic member 15, a telescopic rod 16, a connecting plate 17, and a servo motor 18. The hydraulic cylinder 3 is connected to the fixed plate 14. The second telescopic member 15 and the telescopic rod 16 are horizontally fixed on the fixed plate 14. The second telescopic member 15 and the telescopic rod 16 are both connected to the connecting plate 17. The servo motor 18 is fixed on the connecting plate 17 and is connected to the cylinder 5.

[0035] Further refinements of the embodiments of this utility model, such as... Figure 1 and Figure 2 As shown, the spray assembly 9 includes a suction pump 19 and a spray pipe 20. The suction pump 19 and the inclined spray pipe 20 are fixed on the mounting bracket 7. The input end of the suction pump 19 is connected to a water source (not shown in the figure), and the output end of the suction pump 19 is connected to one end of the spray pipe 20.

[0036] In a further refinement of the embodiment of this utility model, a collection box is placed on the test table 1 below the puncture assembly 8. The collection box is not shown in the figure.

[0037] It should be noted that the hydraulic cylinder 3, the first telescopic component 12, the second telescopic component 15, the servo motor 18, the puncture assembly 8, and the suction pump 19 are all electrically connected to the controller, which is not labeled in the figure.

[0038] The working process of this utility model is as follows:

[0039] First, a fully inflated tire is rolled from the inclined platform 2 onto the test platform 1 (improving ease of operation). Initially, the height of the cylinder 5 is adjusted by the hydraulic cylinder 3 so that the center hole of the tire is aligned with and in front of the cylinder 5 after placement. Then, the translation and flipping assembly 4 drives the cylinder 5 to move horizontally through the center hole of the tire. After the cylinder 5 passes through the center hole of the tire, the controller controls the first telescopic member 12 to move, thereby driving the outer support fixing plates 13 on both sides to move outward along the through hole 11. The tire can then be firmly fixed on the cylinder 5. After fixing, the controller controls the hydraulic cylinder 3 to work, thereby driving the tire to rise to the preset height and move horizontally to the designated area below the puncture assembly 8.

[0040] Then the controller controls the puncture component 8 to work and complete the puncture of a local area of ​​the tire body. After the puncture is completed, the puncture component 8 moves away from the puncture site of the tire body. At the same time, the controller controls the suction pump 19 to work and spray water onto the puncture site. Then, the person can check with their eyes whether there is any air leakage at the puncture site.

[0041] After a partial puncture of the tire body is completed, the controller controls the servo motor 18 to work, thereby driving the cylinder 5 to rotate. The tire body also rotates to a fixed angle. Then, a new local area can be replaced and the puncture and water spraying process can be repeated.

[0042] In summary, by repeating the above process, different parts of the tire carcass can be automatically switched for puncture operations, thereby more comprehensively testing the tire's puncture resistance. After the puncture resistance test is completed, the tire carcass will be brought back into contact with the test bench 1 under the action of the hydraulic cylinder 3 and the translation and flipping component 4. Finally, after the fixation between the cylinder 5 and the tire carcass is released, the tire carcass can be unloaded.

[0043] Compared to existing technologies, this device can automatically puncture the tire carcass and spray water after puncture to check and understand its puncture resistance. At the same time, different areas of the tire carcass can be punctured during the test, thus making the test area more comprehensive. Furthermore, the raising and lowering of the tire does not require manual operation, thus significantly reducing labor intensity and making the tire carcass puncture resistance test process better.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
