Description

Technical Field

[0001] This utility model relates to the technical field of air leakage detection equipment, specifically a rapid air leakage detection device for products. Background Technology

[0002] Die casting, a precision casting technology that uses high pressure to inject molten metal into a mold cavity at high speed and solidify it, occupies a core position in many key fields such as automobile manufacturing, electronic equipment, and aerospace due to its advantages of high efficiency, high precision, and ability to form complex structural parts. For die-cast products with sealing requirements, their sealing performance directly affects the overall performance and safety of the equipment; therefore, rigorous sealing tests are required before leaving the factory.

[0003] Currently, the industry commonly uses specialized airtightness testing equipment to test the sealing performance of die-cast parts. However, this equipment can only detect leaks in die-cast products; it cannot accurately pinpoint the leak location. Since leaks in die-cast parts are often small, appearing as tiny cracks or pores that are difficult to detect with the naked eye, subsequent repairs are inconvenient and challenging. Therefore, we provide a rapid leak detection device to address these issues. Utility Model Content

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.

[0023] Please see Figures 1-5 In this embodiment of the present invention, a rapid product leakage detection device includes a base plate 1. Frames 11 are fixedly connected to both sides of the upper surface of the base plate 1. Sliding crossbars 6 are fixedly connected between the two sides of the frames 11. A clamping mechanism for clamping products is provided between the two sliding crossbars 6. The clamping mechanism includes clamping plates 7, which are respectively disposed between the two ends of the two sliding crossbars 6. Sliding sleeves 22 are fixedly connected to the lower ends of both sides of the clamping plates 7, and the sliding sleeves 22 are slidably connected to the sliding crossbars 6. A clamping mechanism is fixedly connected to the lower ends of the opposite sides of the two clamping plates 7. The support bar 21 is provided on the frame 11, and a pushing assembly for moving the clamping plate 7 is provided on each of the frame 11. The pushing assembly includes two cylinders 12, which are respectively fixedly connected to the frame 11 at both ends of the sliding crossbar 6 by support plates. The output end of the cylinder 12 is fixedly connected to the clamping plate 7. When clamping the product, the product is placed between the two clamping plates 7, and then the cylinder 12 pushes the clamping plate 7, so that the two sliding plates 9 are close to each other. The support bar 21 can support the edge of the product, and thus can cooperate with the clamping plate 7 to achieve clamping and fixing of the product.

[0024] Two sliding rods 8 are fixedly connected at the upper end of the frame 11, and a sliding plate 9 is slidably connected between the two sliding rods 8. A fixed rigid tube 16 is fixedly connected to the lower end of the sliding plate 9, and several nozzles 18 are connected to the lower end of the fixed rigid tube 16. An L-shaped handle 17 is fixedly connected to one side of the sliding plate 9, and a rubber sleeve is wrapped around the vertical rod of the L-shaped handle 17. The L-shaped handle 17 can be used to pull the sliding plate 9 along the sliding rods 8 during use, thereby covering the surface of the product with foam water.

[0025] The base plate 1 is provided with a liquid supply mechanism for conveying foam water into the fixed rigid pipe 16. The liquid supply mechanism includes a water tank 14, which is fixedly connected to one side of the base plate 1. The upper end of the water tank 14 is provided with an inlet 15. The water tank 14 is provided with a water conveying assembly for conveying foam water into the fixed rigid pipe 16. The water conveying assembly includes a water pump 13, which is fixedly connected to one side of the upper end of the water tank 14. The input end of the water pump 13 is connected to the bottom of the water tank 14, and the output end of the water pump 13 is connected to a flexible water pipe 10. The end of the flexible water pipe 10 away from the water pump 13 is connected to the fixed rigid pipe 16. When working, the water pump 13 starts to pump the foam water in the water tank 14 to the flexible water pipe 10, and then to the fixed rigid pipe 16 through the flexible water pipe 10, and sprayed out from the nozzle 18. The inlet 15 facilitates the addition of foam water into the water tank 14.

[0026] One side of the frame 11 is also provided with an air blowing assembly for blowing air onto the product; the air blowing assembly includes a connecting end pipe 23, which is fixedly connected to the frame 11 on one side of the base plate 1. One end of the connecting end pipe 23 is provided with an air inlet 5, and the other end of the connecting end pipe 23 is connected to a flexible air tube 4. The end of the flexible air tube 4 away from the connecting end pipe 23 is connected to an L-shaped rigid air tube 3. The end of the L-shaped rigid air tube 3 near the flexible air tube 4 is fixedly connected to a handle 20. A manual valve 19 is connected to the air tube 3 near the handle 20. During operation, the air inlet 5 is first connected to the air compressor, which provides compressed air. The compressed air enters the L-shaped rigid air tube 3 through the flexible air tube 4 and then sprays out from the L-shaped rigid air tube 3. When detecting product leaks, the L-shaped rigid air tube 3 can be moved at the bottom of the product by holding the handle 20 and blowing air at different locations to find the leaks. The manual valve 19 can control the opening and closing of the L-shaped rigid air tube 3.

[0027] A collection tray 2 is placed on the base plate 1 below the sliding crossbar 6. The collection tray 2 can collect the foam water dripping from the product, preventing the foam water from flowing to the ground and affecting the site environment.

[0028] The working principle of this utility model is as follows: When in use, first connect the air inlet 5 to the air compressor, and the air compressor provides compressed air. During testing, place the product between the two clamping plates 7. The cylinder 12 pushes the clamping plates 7, so that the two sliding plates 9 are close to each other. The set support strip 21 can support the edge of the product, and thus cooperate with the clamping plates 7 to clamp and fix the product. Then, the water pump 13 starts to pump the foam water in the water tank 14 to the soft water pipe 10, and then through the soft water pipe 10 to the fixed hard pipe 16, and spray it out from the nozzle 18. At the same time, pull the L-shaped handle 17 to move the sliding plate 9 along the sliding rod 8, so that the foam water can cover the surface of the product. Then, hold the handle 20 and open the manual valve 19. Compressed air is sprayed out from the L-shaped hard air pipe 3. At the same time, control the L-shaped hard air pipe 3 to move on the lower end face of the product. When there is a leak, the gas will blow out through the leak. The blown gas forms bubbles on the foam water on the upper surface of the product, so that the leak can be detected quickly.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Although this specification describes embodiments, not every embodiment contains only one technical solution. This method of description is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
