Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to an oil pan leak testing device. Background Technology

[0002] The oil pan is the lower part of the crankcase, also known as the lower crankcase. It is located at the bottom of the engine and serves as the outer shell of the crankcase, isolating its interior from the outside world to prevent dust, impurities, and other contaminants from entering the engine and ensuring a clean environment for the engine's internal components.

[0003] As a key component of the engine, the oil pan's sealing performance directly affects the engine's normal operation and service life. The use of an oil pan leak tester is mainly to ensure the oil pan's sealing performance. Compared with traditional methods such as visual inspection and applying soapy water, professional leak testers can detect minute leaks and meet the engine's stringent sealing requirements.

[0004] In the prior art, an oil pan leak testing device has the problem that oil pans usually come in various models, each with different dimensions and interface positions, requiring different molds. When changing the mold, bolts need to be disassembled and positioning components adjusted manually, resulting in excessively long replacement times and affecting production efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an oil pan leak testing device, which aims to solve the problem in the prior art that manual disassembly is required when changing different molds, resulting in excessive time consumption for each change and affecting production efficiency.

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figure 1 and Figure 2 This utility model provides an embodiment of an oil pan leak testing device, comprising a support block 1, an air supply pipe 2 slidably connected to the inner wall of the support block 1, a chuck 3 fixedly connected to the outer wall of the air supply pipe 2, the outer wall of the chuck 3 slidably connected to the inner wall of the support block 1, a sliding plate 4 rotatably connected to the outer wall of the chuck 3, the outer wall of the sliding plate 4 slidably connected to the inner wall of the support block 1, a tension spring 5 fixedly connected to the upper surface of the sliding plate 4, the top end of the tension spring 5 fixedly connected to the inner wall of the support block 1, and a fixing post 6 fixedly connected to the upper surface of the sliding plate 4. A rotating rod 7 is rotatably connected to the outer wall of the fixed column 6. A clamping block 8 is rotatably connected to the outer wall of the rotating rod 7. The outer wall of the clamping block 8 is slidably connected to the inner wall of the support block 1. A rotating rod 9 is rotatably connected to the outer wall of the clamping block 8. The outer wall of the rotating rod 9 is fixedly connected to the inner wall of the support block 1. A flipping assembly is provided on the outer wall of the support block 1. The flipping assembly includes a limiting block 10. The inner wall of the limiting block 10 is fixedly connected to the outer wall of the support block 1. A rotating shaft 11 is provided on the inner wall of the limiting block 10. A housing 12 is fixedly connected to the outer wall of the rotating shaft 11.

[0027] Specifically, when a pressure leak test is required on the oil pan, the oil pan mold can be installed on the upper surface of the support block 1. This allows the oil pan mold to push the air supply pipe 2 to slide against the inner wall of the support block 1. Simultaneously, the air supply pipe 2 pushes the chuck 3 to slide, causing the sliding plate 4 to slide synchronously against the inner wall of the support block 1, ensuring stable sliding of the air supply pipe 2. Rotating the bottom end of the air supply pipe 2 will cause the chuck 3 to lock onto the support block 1, enabling the sliding plate 4 to achieve a self-locking effect. The sliding plate 4 pulls the fixed column 6 to slide, causing the fixed column 6 to pull the rotating rod 7 to rotate synchronously. The rotating rod 7 then pulls the clamping block 8 to rotate against the inner wall of the support block 1, allowing the clamping block 8 to quickly clamp the oil pan mold and prevent leaks. When the bottom shell is pressurized, the oil pan mold shakes, causing air leakage. By rotating the clamping block 8 on the inner wall of the rotating rod 9, and fixing the rotating rod 9 on the inner wall of the support block 1, the clamping block 8 can be prevented from falling off. By installing the support block 1 on the inner wall of the limiting block 10, the limiting block 10 will drive the rotating shaft 11 to rotate on the inner wall of the outer shell 12, allowing the limiting block 10 to drive the support block 1 to flip. The air supply pipe 2 can deliver gas, so that the support block 1 can drive the oil pan to perform underwater leak testing. The support block 1 can quickly replace different oil pan molds to perform leak testing on the oil pan, thereby shortening the mold changeover time and improving production efficiency.

[0028] Reference Figure 1 , Figure 3 and Figure 4 A motor 13 is fixedly connected to the upper surface of the outer casing 12. A turntable 14 is fixedly installed at the output end of the motor 13. The outer wall of the turntable 14 is rotatably connected to the inner wall of the outer casing 12. A swing rod 15 is rotatably connected to the outer wall of the turntable 14. A connecting post 16 is fixedly connected to the inner wall of the swing rod 15. A slider 18 is rotatably connected to the bottom end of the connecting post 16. A slide bar 19 is slidably connected to the outer wall of the slider 18. The lower surface of the slide bar 19 is fixedly connected to the outer wall of the outer casing 12.

[0029] Specifically, after the oil pan is installed, the motor 13 fixed on the upper surface of the outer casing 12 drives the turntable 14 to rotate on the inner wall of the outer casing 12, so that the turntable 14 can stably pull the four sets of swing rods 15 to rotate. The connecting column 16 is driven to slide, so that the connecting column 16 drives the telescopic rod 17 and the slider 18 to slide synchronously. The slider 18 slides on the outer wall of the slide bar 19, and the slide bar 19 is fixed on the outer wall of the outer casing 12, so that the swing rod 15 can slide in a guiding manner while the telescopic rod 17 can slide in conjunction.

[0030] Reference Figures 3-5A telescopic rod 17 is rotatably connected to the top of the connecting column 16. A limit rod 20 is provided on the inner wall of the telescopic rod 17. The outer wall of the limit rod 20 is slidably connected to the inner wall of the limit block 10. A right-angle block 21 is engaged with the outer wall of the limit rod 20. The outer wall of the right-angle block 21 is slidably connected to the outer wall of the limit block 10. A spring 22 is provided on the inner wall of the right-angle block 21. A locking block 23 is fixedly connected to the outer wall of the spring 22. The outer wall of the locking block 23 is slidably connected to the inner wall of the right-angle block 21. The outer wall of the locking block 23 is engaged with the outer wall of the limit rod 20. An adjusting block 24 is rotatably connected to the inner wall of the right-angle block 21.

[0031] Specifically, the telescopic rod 17 drives the limiting rod 20 to slide on the inner wall of the limiting block 10. The sliding of the limiting rod 20 on the inner wall of the telescopic rod 17 allows the limiting rod 20 to extend and retract while simultaneously ensuring the stable rotation of the limiting block 10. The limiting rod 20 drives the right-angle block 21 to slide on the outer wall of the limiting block 10. This ensures that during mechanical air pressure leak testing or underwater air inflation leak testing, the right-angle block 21 will abut against the limiting block 10, preventing it from shifting. When the position of the right-angle block 21 needs adjustment, pushing the right-angle block 21 to slide on the outer wall of the limiting rod 20 will cause the limiting rod 20 to push the locking block 23 to slide on the right-angle block 21. The inner wall of the right-angle block 21 is compressed with spring 22. When the right-angle block 21 slides to the appropriate position, spring 22 will push the locking block 23 to lock the limit rod 20, so that the right-angle block 21 can achieve a self-locking effect. When the swing rod 15 pulls the telescopic rod 17 to center, the right-angle block 21 will drive the adjusting block 24 to center synchronously. The adjusting block 24 rotates on the inner wall of the right-angle block 21, so that the adjusting block 24 can adapt to different oil pans for centering and clamping. The right-angle block 21 can quickly center and clamp different types of oil pans, so that the oil pans can quickly switch between mechanical air pressure leak testing and underwater air pressure leak testing, so that the equipment can adapt to different testing methods.

[0032] Working principle: When this device is needed for mechanical air pressure leak testing, first install the oil pan mold onto the upper surface of the support block 1, and let the air supply pipe 2 push the chuck 3 to slide. When the chuck 3 slides to the appropriate position, rotate the air supply pipe 2 so that the chuck 3 can lock the support block 1 to achieve a self-locking effect. The chuck 3 drives the slide plate 4 to slide, so that the slide plate 4 pulls the fixed column 6 and the tension spring 5. The tension spring 5 is fixed to the inner wall of the support block 1, which can achieve the effect of providing power for the slide plate 4 to reset. The fixed column 6 drives the rotating rod 7 to rotate, so that the rotating rod 7 drives the clamping block 8 to rotate. The clamping block 8 rotates on the inner wall of the rotating rod 9, and the rotating rod 9 is fixed to the inner wall of the support block 1, which can achieve a stable centering and clamping effect for the clamping block 8. At this time, install the oil pan outside the oil pan mold, and then start the motor 13 to drive the adjusting block 24 to clamp the oil pan. This device enables stable leak testing of the oil pan. During underwater leak testing, rotating the limiting block 10 causes the support block 1 to rotate synchronously. The limiting block 10 then drives the rotating shaft 11 to rotate on the inner wall of the outer casing 12, allowing the device to achieve stable rotation. By pulling the limiting rod 20 to slide on the inner wall of the telescopic rod 17, and pulling the right-angle block 21 to the bottom of the limiting rod 20 and abutting against the limiting block 10, the limiting block 10 can be prevented from shifting. The spring 22 installed on the inner wall of the right-angle block 21 pushes the locking block 23 to lock the limiting rod 20, preventing the right-angle block 21 from falling off. At this time, the motor 13 is started to drive the turntable 14 to rotate, causing the turntable 14 to drive the swing rod 15 to rotate while simultaneously causing the connecting column 16 to slide. The connecting column 16 drives the telescopic rod 17 and the slider 18 to slide synchronously. The slider 18 slides on the inner wall of the slide bar 19, which allows the telescopic rod 17 to achieve a stable sliding effect. The telescopic rod 17 pulls the limiting rod 20 to center, so that the limiting rod 20 drives the right-angle block 21 to center and simultaneously drives the adjusting block 24 to center and clamp. This allows the adjusting block 24 to quickly clamp different oil pans. This device can not only quickly change different oil pan molds to conduct leak tests on the oil pans, thereby shortening the mold change time and improving production efficiency, but also quickly center and clamp different types of oil pans, allowing the oil pans to be quickly switched between mechanical air pressure leak tests and underwater air pressure leak tests, so that the equipment can adapt to different testing methods.
