Description

Technical Field

[0001] This utility model relates to the field of testing device technology, specifically to a testing device for automotive O-rings. Background Technology

[0002] As a critical seal in automobiles (such as engine oil seals, transmission seals, and brake line connectors), the sealing performance of O-rings directly determines the reliability of the system. If the seal fails, it can lead to serious consequences such as lubricant leakage causing engine wear, coolant loss leading to overheating, and insufficient brake pressure endangering driving safety. According to statistics, about 15% of engine failures in the automotive industry are directly related to seal failure, and seal testing is the last line of defense to avoid such problems.

[0003] O-rings are indispensable sealing elements in automobile manufacturing, widely used in core components such as engines, transmissions, braking systems, fuel systems, and cooling systems. Therefore, conventional dimensional inspections, such as outer diameter and wire diameter, and appearance inspections, such as cracks and burrs, can only detect obvious defects but cannot simulate the sealing effect under actual working conditions. For example, an O-ring may not have cracks on its surface but may still leak due to uneven hardness. However, by conducting air tightness tests or pressure decay tests, the leakage rate of O-rings under high pressure conditions can be directly measured to ensure that they will not fail in actual use.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 As shown, an O-ring testing device for automobiles includes a base plate 1 and a fixed tank 2. The fixed tank 2 is installed on the top of the base plate 1, and a conveying component 3 is provided on the top of the base plate 1.

[0021] The fixed tank 2 can be used to temporarily store pressurized media, such as air, and the conveying component 3 can be used to transport the pressurized media in the fixed tank 2 to the fixed plate 4, thereby increasing the pressure in the internal cavity when the limiting plate 8 and the fixed plate 4 are closed.

[0022] A fixing plate 4 is set on the top of the base plate 1. A fixing frame 5 is fixedly connected to the top of the fixing plate 4, and a driving component 6 is provided on the outside of the fixing frame 5.

[0023] The fixing plate 4 can provide a fulcrum for the installation of the fixing frame 5, the fixing frame 5 can provide a fulcrum for the installation of the driving component 6, and the driving component 6 can drive the connecting frame 7 to move vertically, thereby facilitating the compression of the limiting plate 8 and increasing the sealing performance when the limiting plate 8 and the fixing plate 4 are closed.

[0024] The connecting bracket 7 is located on the outside of the driving component 6, and the limiting plate 8 is located above the fixing plate 4.

[0025] The connecting frame 7 can easily compress the limiting plate 8, and the limiting plate 8 can easily cooperate with the fixing plate 4 to form a detection cavity.

[0026] The mounting groove 10 is formed on the inner wall of the fixing plate 4, and the O-ring body 9 is installed on the inner wall of the mounting groove 10.

[0027] Mounting slot 10 provides space for the inspection of O-ring body 9.

[0028] The inner wall of the fixed tank 2 is connected to a fixed pipe 11, and a valve 12 is installed on the outside of the fixed pipe 11.

[0029] The use of the fixed pipe 11 and the valve 12 together facilitates the replenishment of the pressurized medium inside the fixed tank 2, thereby reducing the time spent when replacing the fixed tank 2.

[0030] A support frame 13 for supporting the fixed plate 4 is fixedly connected to the top of the base plate 1, and a pressure sensor 14 is installed on the outside of the fixed plate 4.

[0031] The support frame 13 can connect the base plate 1 and the fixing plate 4, thereby facilitating the installation of the fixed tank 2 and the conveying component 3. The pressure sensor 14 can detect the pressure in the cavity inside the limiting plate 8 and the fixing plate 4, thereby detecting the sealing performance of the O-ring body 9 based on the pressure level in the cavity. The pressure sensor 14 is existing technology. The pressure sensor 14 is a core device used to measure the pressure of gas or liquid. It comes in various types, such as mechanical and electronic. Its working principle is based on mechanical, electrical, or optical effects. The core components are a Bourdon tube, a connecting rod, and a pointer. Pressure causes the Bourdon tube to deform, and the pointer is driven to rotate through the connecting rod to indicate the pressure value. Further details are omitted here.

[0032] A fixing rod 15 is fixedly connected to the top of the fixing plate 4, and the outer side of the fixing rod 15 is slidably connected to the inner wall of the limiting plate 8. A limiting spring 16 for supporting the limiting plate 8 is provided on the outer side of the fixing rod 15.

[0033] The fixing rod 15 can assist the limiting plate 8 in sliding, so as to facilitate the use of the limiting spring 16 to lift the limiting plate 8 after the test is completed, thereby facilitating the removal of the O-ring body 9.

[0034] A support plate 17 is fixedly connected to the outside of the fixed frame 5. A limit rod 18 is fixedly connected to the top of the support plate 17. The end of the limit rod 18 away from the support plate 17 is fixedly connected to the outside of the fixed frame 5. The outside of the limit rod 18 is slidably connected to the inner wall of the connecting frame 7.

[0035] The limiting rod 18 can assist the connecting frame 7 in sliding, and the support plate 17 can support the limiting rod 18, thereby increasing the stability of the connecting frame 7 when sliding.

[0036] The conveying component 3 includes a booster pump 31 installed on the top of the base plate 1. The air inlet of the booster pump 31 is connected to the inner wall of the fixed tank 2. The air outlet of the booster pump 31 is connected to a conveying pipe 32. The end of the conveying pipe 32 away from the booster pump 31 is connected to the inner wall of the fixed plate 4.

[0037] The booster pump 31 can deliver the pressurized medium inside the fixed tank 2 to the cavity formed by the limiting plate 8 and the fixed plate 4 through the delivery pipe 32, thereby increasing the pressure inside the cavity and facilitating the testing of the sealing performance of the O-ring body 9. The booster pump 31 is existing technology. Through mechanical drive or gas dynamics principle, it converts the input low-pressure gas into high-pressure gas. After the output gas enters the pump body, it is accelerated by the impeller or vortex disk. The high-speed gas is decelerated in the diffuser, and the pressure increases. The gas is compressed through multiple stages, and the pressure gradually increases. This will not be elaborated further here.

[0038] The driving component 6 includes a motor 61 mounted on the top of the fixed frame 5. The output end of the motor 61 is fixedly connected to a screw 62, and the outer side of the screw 62 is rotatably connected to the inner wall of the fixed frame 5. The outer side of the screw 62 is threadedly connected to the inner wall of the connecting frame 7.

[0039] The motor 61 can drive the screw 62 to rotate, and the screw 62 can drive the connecting frame 7 to move vertically. The vertical movement of the connecting frame 7 presses the limiting plate 8 until it fits against the fixing plate 4, thereby forming a cavity during testing.

[0040] Working principle: First, place the O-ring body 9 into the mounting groove 10. After installation, start the motor 61. The motor 61 drives the screw 62 to rotate. The screw 62 drives the connecting frame 7 to move vertically. The vertical movement of the connecting frame 7 can squeeze the limiting plate 8 until it fits against the fixing plate 4, thus forming a cavity for testing. At this time, start the booster pump 31. The booster pump 31 delivers the pressurized medium in the fixing tank 2 into the cavity. At this time, you can observe the value displayed by the pressure sensor 14. If the pressure in the cavity increases relatively slowly, it means the sealing effect is poor. If it rises steadily, the sealing effect is good.
