Technical Field

[0001] This utility model belongs to the field of equipment testing technology, specifically relating to a leak detection tool. Background Technology

[0002] In the manufacturing process of industrial control equipment, these devices often integrate multiple functions. Among them, the sealing performance of the equipment housing is a crucial indicator for ensuring the long-term stable operation of the equipment. Leaks in the housing can affect the normal operation of internal electronic components, thereby reducing the reliability and lifespan of the equipment.

[0003] Leak testing of equipment housings is generally performed using tooling. Most existing tooling uses manual sealing, which is prone to problems such as incomplete sealing of the leak testing ports and unstable inflation pressure. Manual sealing also suffers from low testing efficiency. Furthermore, the structure of existing tooling is relatively fixed, making it difficult to adapt to different specifications of equipment housings, and the testing operation is complex, which can easily lead to poor testing accuracy.

[0004] Therefore, existing leak detection equipment is insufficient to meet the demands of modern automated production for efficient and high-precision detection. Utility Model Content

[0039] The present invention will be further described in detail below with reference to experimental examples and specific embodiments. However, this should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0040] Example 1 To address the problems of inadequate sealing of the leak test port, complex operation, low testing efficiency, and difficulty in adapting to different specifications of equipment housings caused by existing tooling, this embodiment 1 provides a leak test tooling that can effectively improve the testing efficiency of housing airtightness.

[0041] like Figure 1 As shown, the leak testing fixture provided in this embodiment 1 includes a frame body, a test adjustment component, and a leak testing execution component.

[0042] In use, the product is carried inside the frame body, and air is injected into the leak detection port of the product through the leak detection execution component. The product carried inside the frame body can be the housing of industrial control equipment, etc. The test adjustment component can move the leak detection execution component away from or closer to the leak detection port of the product, thus enabling this embodiment 1 to adaptively adjust the position of the leak detection execution component according to the actual position of the product's leak detection port. This allows this embodiment 1 to adapt to leak detection of housings of different sizes. Furthermore, by adaptively adjusting the leak detection execution component according to the position of the product's leak detection port, this embodiment 1 can solve the problem of incomplete sealing caused by mismatch between the product's leak detection port and the leak detection execution component. This embodiment 1 is easy to operate and can effectively improve testing efficiency.

[0043] In this embodiment 1, the frame body serves as the load-bearing element of the product and forms the basis for leak testing. Preferably, the frame body includes a first fixing block 1, a first side strip 2, a second fixing block 3, and a second side strip 4 connected end to end. The first fixing block 1, the first side strip 2, the second fixing block 3, and the second side strip 4 constitute the frame body of the testing fixture, providing a basic installation and positioning for the product. The entire frame body structure is simple and easy to manufacture.

[0044] Furthermore, the first fixing block 1, the first side strip 2, the second fixing block 3, and the second side strip 4 are all detachably connected, which can further improve the adaptability to products of different sizes, effectively solve the problem of the limited use environment of existing tooling, and expand the scope of tooling application.

[0045] In this embodiment 1, the leak detection execution component includes an inflation head 6, which has an inflation interface for connecting to an external device and an inflation nozzle for connecting to the product's leak detection port.

[0046] In this embodiment 1, the inflation interface and inflation nozzle on the inflation head 6 can effectively ensure that the leak detection execution component has the function of inflating the leak detection port of the product.

[0047] In this embodiment 1, the test adjustment component is installed on the outside of the first fixed block 1 via the adjustment seat 9. The test adjustment component includes an adjustment screw 7. One end of the adjustment screw 7 passes through the first fixed block 1 and is connected to the inflation head 6 of the leak detection execution component. The adjustment screw 7 is threadedly connected to the first fixed block 1.

[0048] The threaded connection effectively ensures that the test adjustment component can move the leak detection execution component closer to or away from the leak detection port of the product, which is a preferred embodiment of this Example 1.

[0049] More preferably, the axis of the adjusting screw 7 is the same as the axis of the product leak detection port, thereby effectively ensuring the efficiency of the test adjustment component when adjusting the position of the leak detection execution component.

[0051] When a product has multiple ports, in this embodiment 1, non-leakage testing ports can be sealed with plugs 5, and leak testing ports can be tested by inflating with air heads 6. During testing, gas at a specific pressure, such as dry air, is injected into the leak testing ports of the product through the air heads 6. The sealing performance is determined by detecting the amount of gas leakage, and the product's qualification is determined based on the leakage amount. Plugs 5 are used to seal ports on the product that do not require leak testing, thus ensuring that the leak testing gas flows only along a designated path.

[0052] The test adjustment assembly also includes a limit block 8, which is fitted onto the adjustment screw 7 to limit the thread stroke of the adjustment screw 7. The combination of the adjustment screw 7 and the limit block 8 enables a precise and controllable adjustment mechanism. The adjustment screw 7 can rotate within the adjustment seat 9 to achieve fine-tuning of its position, while the limit block 8 simultaneously limits the adjustment stroke. This ensures accurate docking between the test adjustment assembly and the test product, while also preventing over-adjustment that could damage the tooling or product, thus improving leak detection accuracy and safety.

[0054] The second step is to adjust the position of the plug 5 by adjusting the adjusting screw 7 and use the limiting block 8 to prevent over-adjustment, so that the plug 5 seals the port on the product that does not require air inflation for leak testing, ensuring a tight seal.

[0055] The third step is to adjust the position of the inflation head 9 by adjusting the adjusting screw 7, and use the limit block 8 to prevent over-adjustment, so that the inflation head 9 is precisely connected to the inflation port of the product.

[0056] The fourth step is to connect the external inflation device to the inflation head 9 and inflate the product with the set pressure, such as 0.5MPa dry air according to the product standard, and maintain the pressure for a certain period of 30 seconds.

[0057] The fifth step is to use a gas leak detector to check for gas leaks around the product. If the leakage is within the standard allowable range, such as less than 5 mL / min, the casing is deemed to be airtight; otherwise, it is deemed to be unqualified.

[0101] The fifth step is to use a gas leak detector to check for gas leaks around the product. If the leakage is within the standard allowable range, such as less than 5 mL / min, the casing is deemed to be airtight; otherwise, it is deemed to be unqualified.

[0102] This embodiment 3 can solve the problems caused by the existing tooling, such as poor sealing of the housing leak test port, complicated operation, low testing efficiency, and difficulty in adapting to housings of different specifications, and can effectively improve the testing efficiency of housing airtightness.

[0103] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
