[0002] Seals are materials or parts that prevent fluids or solid particles from leaking between adjacent joint surfaces and prevent external impurities such as dust and moisture from invading parts inside machinery and equipment. They are usually in the shape of a ring.

[0003] In the field of modern industrial manufacturing, seals are a key component, and their sealing performance is crucial to ensure the normal operation of the entire equipment. In order to ensure that the seals can meet the expected sealing effect after production, sealing performance testing has become an indispensable process. At present, there are many seal detection devices on the market, which aim to improve detection efficiency and accuracy.

[0004] Among them, the rubber seal air tightness detection device with application number CN202020842871.9 adopts the combination of conical plug-in piles and conical detection grooves to perform air tightness detection on the seals, and ensures the convenience of taking the seals to avoid getting stuck in the detection equipment.

[0005] However, although this detection device has improved the detection efficiency to a certain extent, it still has some shortcomings. In actual operation, after each sample is detected, it is necessary to stop the machine to clamp and install the next sample to be tested before the next test can be carried out. This testing method is inefficient and wastes a lot of time. Utility Model Content

[0035] Please see attached Figure 1-Figure 5 As shown, the utility model provides a rubber seal sealing detection device, including a housing 1, a circular base 2 is rotatably connected inside the housing 1, a controller 6 is installed on the front of the housing 1, and also includes:

[0036] The electric push rod 3 is fixedly connected to the top surface of the housing 1 by a bracket, and a pressing block 4 is fixedly installed at the telescopic end of the electric push rod 3;

[0037] A detection mechanism 5, the detection mechanism 5 is arranged on the circular base 2;

[0038] Among them, the detection mechanism 5 includes a water storage tank 51, which is arranged in a ring-shaped distribution on the circular base 2, and a slide groove is arranged on the inner wall of the water storage tank 51, a support part 53 is arranged in the water storage tank 51, a water storage tank 52 is arranged at the center of the circular base 2, and a through groove for connecting the water storage tank 51 and the water storage tank 52 is arranged on the top surface of the circular base 2, an air transmission part 54 is arranged at the lower end of the circular base 2, and a driving part 55 is arranged in the shell 1 for driving the circular base 2 to rotate.

[0039] In this embodiment, first, the rubber seal to be tested is securely placed on the support part 53 to ensure that it is placed firmly. Then, the electric push rod 3 is controlled to extend so that it pushes the pressing block 4 to press tightly on the seal to ensure the accuracy of the test. Next, the air delivery part 54 injects air to test the sealing performance of the seal. The driving part 55 can be used to drive the circular base 2 to rotate to achieve continuous and comprehensive testing.

[0040] During the detection process, if the support part 53 is pressed down into the water storage tank 51, if the water in the water storage tank 51 overflows, it will flow into the water storage tank 52 according to the designed through-channel path, thereby effectively preventing water leakage and ensuring the cleanliness and safety of the detection environment.

[0041] In a preferred embodiment, please refer to Figure 3-Figure 5 The support portion 53 includes a slider 531, which is slidably connected in a slide groove on the inner wall of the water storage tank 51. A hollow rod 532 is fixedly connected at the center of the slider 531, and an air inlet hole is opened in a ring-shaped manner at the lower end of the hollow rod 532. A support block 533 is fixedly connected to the upper end of the hollow rod 532. A spring 534 is fixedly connected to the bottom surface of the slider 531, and the other end of the spring 534 is fixedly connected to the bottom surface of the inner cavity of the water storage tank 51.

[0042] In this embodiment, in order to ensure that the air tightness test of the rubber seal is accurate and reliable, firstly, a proper amount of clean water needs to be injected into the water storage tank 51. Then, the seal to be tested is properly placed in the groove on the support block 533, and the electric push rod 3 is extended to drive the pressing block 4 to move downward until the pressing block 4 and the support block 533 together firmly clamp the seal.

[0043] Under the continuous extension of the electric push rod 3, the support block 533 is pressed down, and the hollow rod 532 is driven to move down synchronously. At this time, the slider 531 will slide down along the preset slide groove in the water storage tank 51, and the spring 534 will be squeezed. When the lower end of the hollow rod 532 enters the gas pipe 541, the gas can enter the interior through the air inlet hole at the lower end of the hollow rod 532, and then go up along the hollow rod 532 and enter the cavity formed between the pressing block 4 and the support block 533.

[0044] Next, please refer to Figure 2-Figure 4 The air delivery part 54 includes an air delivery pipe 541, which is connected to the lower end of the water storage tank 51, and the lower end of the hollow rod 532 is piston-plugged into the air delivery pipe 541, the lower end of the air delivery pipe 541 is connected to an air storage disk 542, and the lower end of the air storage disk 542 is rotatably connected to an air intake pipe 543 through a sealed bearing, and an air pump 544 is fixedly installed on the bottom surface of the shell 1, and the exhaust end of the air pump 544 is connected to the air intake pipe 543.

[0045] In this embodiment, during the detection process, the air pump 544 needs to be started to input air into the air storage disk 542 through the air inlet pipe 543, and then the air storage disk 542 transports the air to the air delivery pipe 541. For the hollow rod 532 that has been pressed down, the air inlet hole at the lower end will allow air to enter; while for the hollow rod 532 that has not been pressed down, the air inlet hole at the lower end is effectively blocked to prevent air from entering.

[0046] Secondly, please refer to Figure 5 The driving unit 55 includes a motor 551, which is fixedly installed in the housing 1. The upper end of the output shaft of the motor 551 is fixedly connected to a small gear 552, and the outer wall of the circular base 2 is fixedly sleeved with a large gear 553.

[0047] In this embodiment, through the design of the driving part 55, the starting motor 551 can drive the small gear 552 to rotate, and then the small gear 552 and the large gear 553 are meshed and driven to realize the rotation of the circular base 2. The motor 551 is designed to be an intermittent rotation mode, rotating sixty degrees each time, ensuring that a support block 533 is located just below the pressing block 4 during each inspection. This design allows the staff to conveniently take and place the seals in other support blocks 533 while inspecting one seal, thereby improving the inspection efficiency.

[0048] In a preferred embodiment, please refer to Figure 1-Figure 4 The controller 6 is electrically connected to the electric push rod 3 , the motor 551 and the air pump 544 .

[0049] In this embodiment, the controller 6 is responsible for coordinating and controlling the operation of the electric push rod 3, the motor 551 and the air pump 544. Through precise electrical connections, the controller 6 can obtain the working status of these components in real time and accurately control them according to preset programs or external instructions.

[0050] Under the command of the controller 6, the electric push rod 3 can be extended and retracted at a predetermined speed and stroke, thereby driving the relevant mechanical structure to complete a specific action. The motor 551 controls the speed and direction through the controller 6. The air pump 544 is also precisely controlled by the controller 6. By adjusting the working parameters of the air pump 544, such as air pressure and flow, the controller 6 can achieve precise control of the performance of the pneumatic system.

[0051] In summary, through the electrical connection between the controller 6 and the electric push rod 3, the motor 551 and the air pump 544, the entire system can achieve an efficient and stable working state and meet the needs of different application scenarios.

[0052] Next, please refer to Figure 4-Figure 5 A T-shaped ring groove is provided on the support block 533 .

[0053] In this embodiment, the T-shaped ring groove provided on the support block 533 improves the convenience of taking the seal. In actual operation, the staff can easily put the seal into or take it out of the T-shaped ring groove without worrying about it getting stuck inside the detection equipment, which greatly improves work efficiency.

[0054] In addition, the design of the T-ring groove effectively prevents the seal from shifting or falling off during use, ensuring the stability of the sealing effect.

[0055] The working principle of the utility model is:

[0056] To ensure that the air tightness test of the rubber seal is accurate and reliable, firstly, a proper amount of clean water needs to be injected into the water storage tank 51. Then, the seal to be tested is properly placed in the groove on the support block 533, and the electric push rod 3 is extended to drive the pressing block 4 to move downward until the pressing block 4 and the support block 533 together firmly clamp the seal.

[0057] Under the continuous extension of the electric push rod 3, the support block 533 is pressed down, and the hollow rod 532 is driven to move down synchronously. At this time, the slider 531 will slide down along the preset slide groove in the water storage tank 51, and the spring 534 will be squeezed. When the lower end of the hollow rod 532 enters the gas pipe 541, the gas can enter the interior through the air inlet hole at the lower end of the hollow rod 532, and then go up along the hollow rod 532 and enter the cavity formed between the pressing block 4 and the support block 533.

[0058] During the test, the air pump 544 needs to be started to input air into the air storage disk 542 through the air inlet pipe 543, and then the air storage disk 542 transports the air to the air delivery pipe 541. For the hollow rod 532 that has been pressed down, the air inlet hole at the lower end will allow air to enter; while for the hollow rod 532 that has not been pressed down, the air inlet hole at the lower end is effectively blocked to prevent air from entering.

[0059] In addition, through the design of the driving part 55, the starting motor 551 can drive the small gear 552 to rotate, and then the small gear 552 and the large gear 553 are meshed and driven to realize the rotation of the circular base 2. The motor 551 is designed to be an intermittent rotation mode, rotating sixty degrees each time, ensuring that a support block 533 is located just below the pressing block 4 during each inspection. This design allows the staff to conveniently take and place the seals in other support blocks 533 while inspecting one seal, thereby improving the inspection efficiency.

[0060] Through the above steps, the air tightness of the rubber seal can be accurately judged. If bubbles appear in the water storage tank 51, it indicates that the sealing performance of the seal is poor; on the contrary, if no bubbles are generated, it proves that the sealing performance of the seal is good. After the test is completed, the electric push rod 3 is controlled to shorten, so that the pressure block 4 can move up. At this time, the spring 534 gradually returns to its original state and drives the support block 533 to move up and reset, preparing for the next test.

[0061] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
