[0002] The air-water dual-test device for automotive engine housings is a specialized piece of equipment used in the automotive manufacturing industry to test the sealing performance of automotive engine housings. This device comprehensively tests the sealing performance of the engine housing using both air and water testing methods to determine if there are any leaks, ensuring the engine housing functions properly during use and preventing malfunctions caused by poor sealing. It is suitable for the quality inspection stage of automotive engine housing production.

[0003] Traditional automotive engine housing inspection devices suffer from significant shortcomings in terms of ease of operation and adaptability. Most devices suffer from poorly designed clamping and transfer structures, making it inconvenient to handle engine housings, resulting in cumbersome procedures and reduced inspection efficiency. Furthermore, existing devices have fixed clamping sizes, making them unadjustable for different engine housing dimensions, thus limiting their application and restricting their scope to specific specifications. This makes it difficult to meet the demands for efficient and accurate automotive engine housing inspection. Therefore, we propose an air-water dual-inspection device for automotive engine housings. Summary of the Invention

[0004] One of the technical problems this application aims to solve is that the clamping size of existing automobile manufacturing equipment is fixed and cannot be adjusted according to different sizes of engine housings, resulting in poor adaptability and difficulty in meeting the needs of efficient and accurate detection of automobile engine housings.

[0005] To address the aforementioned technical problems, this application provides an air-water dual-inspection device for automotive engine housings, comprising a base, a placement groove on one side of the inner wall of the base, a first bracket fixedly connected to the upper outer wall of the base, a controller fixedly connected to the upper outer wall of the first bracket, an airtightness testing device connected to the lower middle of the controller, a fixed rod fixedly connected to the lower end of the controller, a worktable fixedly connected to the lower end of the fixed rod, a slide rail fixedly connected to both sides of the upper outer wall of the worktable, a second cylinder fixedly connected to the middle of the upper outer wall of the worktable, a sliding plate movably connected to the upper outer wall of the slide rail, and a sliding groove provided at the lower end of the sliding plate.

[0006] In some embodiments, a groove is provided at the lower end of the slide plate, a waterproof motor is fixedly connected to one side of the inner wall of the groove, a rotating rod is connected to the upper end of the waterproof motor, a rotating block is fixedly connected to the outer wall of the upper end of the rotating rod, a connecting rod is movably connected to both sides of the rotating block, a support plate is movably connected to the side of the connecting rod away from the rotating block, a sliding rod is movably connected to the lower end of the support plate, a side plate is fixedly connected to both sides of the sliding rod, and the lower end of the side plate is fixedly connected to the outer wall of the upper end of the slide plate.

[0007] In some embodiments, a display is connected to one outer wall of the controller, a control button is connected to one outer wall of the controller, a second bracket is fixedly connected to one side of the first bracket, a first cylinder is connected to one side of the second bracket, a support plate is connected to the lower end of the first cylinder, a water cylinder is fixedly connected to the middle of the upper outer wall of the support plate, and two limit rods are movably connected to both sides of the support plate.

[0008] In some embodiments, the support plate and the water tank are connected to the inner wall of the placement groove opened on one side of the base.

[0009] In some embodiments, the base and the controller are fixedly connected by a first bracket and a limiting rod.

[0010] In some embodiments, the slide groove at the lower end of the slide plate is slidably connected to the slide rail provided on the upper outer wall of the worktable.

[0011] In some embodiments, a second cylinder is provided near the upper outer wall of the worktable, with the lower end of a waterproof motor located on one side of the inner wall of the groove.

[0012] In some embodiments, one side of the second cylinder is fixedly connected to one side of the inner wall of the groove opened at the lower end of the slide plate.

[0013] This utility model has at least the following beneficial effects: In use, this invention excels in the convenience and adaptability of its clamping and transferring structure, which comprises a sliding plate, slide rail, second cylinder, waterproof motor, rotating rod, rotating block, connecting rod, support plate, and slide bar. Activation of the second cylinder causes the sliding plate to slide along the slide rail, facilitating the removal of the engine casing. The waterproof motor drives the rotating rod and rotating block to rotate, which in turn causes the support plate to move in opposite directions along the slide bar via the connecting rod. This allows for adjustment of the clamping size to accommodate engine casings of different dimensions, enhancing the device's practicality. Furthermore, the waterproof motor's waterproof performance ensures that it will not be affected by short circuits during watertightness testing, guaranteeing the smooth progress of the testing process. In use, the airtightness testing device and the water cylinder work together to ensure the accuracy and comprehensiveness of the detection. The airtightness testing device can test the airtightness of the engine casing, and the data is displayed on a screen. It can also pressurize air by controlling a button to detect leaks. The first cylinder drives the support plate and the water cylinder to move longitudinally, and the water in the water cylinder can immerse the engine casing. By observing the bubbles, the integrity of the casing seal can be further confirmed. The combination of these two detection methods significantly improves the accuracy of the test results. In use, this invention ensures operational stability through the combined efforts of multiple components. When the water cylinder is raised, it slides along the limiting rod between the controller and the base, ensuring stable displacement without deviation. The worktable is smaller than the water cylinder, guaranteeing that the water cylinder completely submerges the worktable and the engine casing above it when raised, providing a stable environment for water tightness testing. All components are securely connected via brackets and fixing rods, forming a reliable overall structure that ensures the stability of each step of the testing process. Attached Figure Description

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.

[0017] Example 1: Please refer to Figure 1-4This utility model provides a technical solution: a dual air and water inspection device for an automobile engine housing, including a base 1, a placement groove 2 on one side of the inner wall of the base 1, a first bracket 3 fixedly connected to the upper outer wall of the base 1, a controller 4 fixedly connected to the upper outer wall of the first bracket 3, an airtightness testing device 26 connected to the lower middle of the controller 4, a fixing rod 12 fixedly connected to the lower end of the controller 4, a worktable 13 fixedly connected to the lower end of the fixing rod 12, a slide rail 14 fixedly connected to both sides of the upper outer wall of the worktable 13, a second cylinder 15 fixedly connected to the middle of the upper outer wall of the worktable 13, a sliding plate 16 movably connected to the upper outer wall of the slide rail 14, a sliding groove 17 opened at the lower end of the sliding plate 16, and the sliding groove 17 at the lower end of the sliding plate 16 connecting with the slide rail 16 on the upper outer wall of the worktable 13. 4. Sliding connection: A groove 18 is provided at the lower end of the slide plate 16. One side of the second cylinder 15 is fixedly connected to one side of the inner wall of the groove 18 at the lower end of the slide plate 16. A waterproof motor 19 is fixedly connected to one side of the inner wall of the groove 18. The lower end of the waterproof motor 19 is close to the second cylinder 15 located on the upper outer wall of the worktable 13. A rotating rod 20 is connected to the upper end of the waterproof motor 19. A rotating block 21 is fixedly connected to the upper outer wall of the rotating rod 20. A connecting rod 22 is movably connected to both sides of the rotating block 21. A carrying plate 23 is movably connected to the side of the connecting rod 22 away from the rotating block 21. A sliding rod 24 is movably connected to the lower end of the carrying plate 23. A side plate 25 is fixedly connected to both sides of the sliding rod 24. The lower end of the side plate 25 is fixedly connected to the upper outer wall of the slide plate 16.

[0018] In this embodiment, a base 1 is designed with a placement groove 2 on one side of its inner wall. A controller 4 is fixedly connected to the upper outer wall of the base 1 via a first bracket 3. A workbench 13 is fixedly connected to the lower end of the controller 4 via a fixing rod 12. The lower end of the workbench 13 is connected to the upper end of the water tank 10, and its size is smaller than that of the water tank 10. Therefore, when the water tank 10 is raised, it can be submerged for water tightness testing. A slide rail 14 is fixedly connected to the upper end of the workbench 13. A slide plate 16 is slidably connected to the outer wall of the slide rail 14 via a sliding groove 17. A second cylinder 15 is fixedly connected to the middle of the upper outer wall of the workbench 13. A groove 18 is provided on one side of the lower end of the slide plate 16. A waterproof motor 19 is fixedly connected to one side of the inner wall of the groove 18. The waterproof motor 19 is located on one side of the upper end of the second cylinder 15. One side of the second cylinder 15 is fixedly connected to one side of the inner wall of the groove 18 at the lower end of the slide plate 16. Therefore, when the second cylinder 15 is started, i.e. The slide plate 16 can be offset on one side of the outer wall of the slide rail 14, allowing the engine housing to be removed. The waterproof motor 19 is a waterproof motor, which will not be affected by short circuits during water tightness testing. The upper end of the waterproof motor 19 is equipped with a rotating rod 20, which extends to one side of the upper outer wall of the slide plate 16 and is fixedly connected to a rotating block 21. The two sides of the rotating block 21 are movably connected to the support plate 23 via connecting rods 22. The lower end of the support plate 23 is equipped with a sliding rod 24, which is fixedly connected to the upper outer wall of the slide plate 16 via a side plate 25. Therefore, when the waterproof motor 19 is started, it drives the rotating rod 20 to rotate, which in turn causes the rotating block 21 to offset. This causes the support plate 23 to offset on one side of the outer wall of the sliding rod 24 via the connecting rods 22, so that the two support plates 23 move towards each other. This allows for size adjustment to accommodate engine housings of different sizes, making the device practical.

[0019] Example 2: Please refer to Figure 1-2 A display 5 is connected to one side of the outer wall of the controller 4, and a control button 6 is connected to one side of the outer wall of the controller 4. A second bracket 7 is fixedly connected to one side of the first bracket 3, and a first cylinder 8 is connected to one side of the second bracket 7. A support plate 9 is connected to the lower end of the first cylinder 8, and a water cylinder 10 is fixedly connected to the middle of the upper outer wall of the support plate 9. The support plate 9 and the water cylinder 10 are connected to the inner wall of the placement groove 2 opened on one side of the base 1. Two limit rods 11 are movably connected to both sides of the support plate 9. The base 1 and the controller 4 are fixedly connected through the first bracket 3 and the limit rods 11.

[0020] In this embodiment, a display 5 and a control button 6 are connected to one side of the controller 4, and an airtightness detection device 26 is provided at the lower end of the controller 4. Therefore, the airtightness detection device 26 can perform airtightness detection on the engine housing. The data displayed by the detection will be shown on the display 5. Air can be pressurized by the control button 6 to detect whether there is a leak in the engine housing. A second bracket 7 is fixedly connected to the side wall of the first bracket 3. A first cylinder 8 is connected to one side of the second bracket 7. A support plate 9 is fixedly connected to the lower end of the first cylinder 8, and a water cylinder 10 is fixedly connected to the middle of the upper end of the support plate 9. Therefore, the first cylinder 8 can drive the support plate 9 and the water cylinder 10 to move longitudinally. The water cylinder 10 can be filled with water. Therefore, when the engine housing is submerged in the water cylinder 10, bubbles can be observed to further confirm the sealing integrity of the housing. When the water cylinder 10 is lifted, it will slide on one side of the outer wall of the limiting rod 11 provided between the controller 4 and the base 1 to ensure the stability of the water cylinder 10's offset and prevent offset from occurring.
