Description

Technical Field

[0001] This utility model relates to the field of water pressure testing technology, specifically a water pressure testing device for testing the sealing performance of automotive parts. Background Technology

[0002] It is mainly used to check the sealing performance of automotive parts under water pressure to ensure that they can effectively prevent water from entering, preventing corrosion or damage in actual use. This device simulates the water environment that automotive parts may encounter in daily use and conducts pressure tests to detect their waterproof performance.

[0003] During hydrostatic testing of components, the components are prone to swaying and becoming unstable due to the water pressure environment. Failure to clamp and position them properly can interfere with the hydrostatic sealing of the components, affecting the accuracy of the test data. This data deviation may lead to unqualified components being mistakenly judged as qualified, ultimately resulting in leaks, insufficient pressure resistance, and other problems in actual use, creating potential safety hazards. Utility Model Content

[0006] A test bucket is fixed to the top of the operating table. The top of the test bucket is rotatably connected to a sealing cover via a hinge. The inner cavity of the test bucket is provided with a clamping assembly for stable testing. The clamping assembly includes clamping plates and cylinders. Two clamping plates are disposed in the inner cavity of the test bucket. One side of the clamping plate is fixedly connected to the cylinder, and one side of the cylinder is fixedly connected to the inner wall of the test bucket.

[0007] Preferably, both sides of the clamping plate are connected to sliding sleeves, and the inner cavity of the sliding sleeve is fitted with a stabilizing rod, and both sides of the stabilizing rod are fixedly connected to the inner wall of the test barrel.

[0008] Preferably, a buffer spring is fixedly connected to one side of each clamping plate, and a buffer plate is fixedly connected to one side of each buffer spring. One side of the buffer plate is in close contact with the automotive parts.

[0009] Preferably, an inflation gauge is fixedly connected to one side of the positioning plate, an inflation pipe is connected to one side of the inflation gauge via a flange, and one side of the inflation pipe is placed inside the test barrel.

[0012] Preferably, a light is fixedly connected to the bottom of one side of the positioning plate to facilitate observation of the internal state of the test barrel.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention, through the design of the clamping assembly, allows for the relative movement of the clamping plate by a cylinder after the automotive parts are placed inside the test chamber.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figures 1-5 As shown, a hydrostatic testing device for testing the sealing performance of automotive parts includes an operating platform 1 and a positioning plate 2 mounted on one side of the top of the operating platform 1, and further includes:

[0023] The test bucket 3 is fixed to the top of the operating table 1. The top of the test bucket 3 is rotatably connected to the sealing cover 4 via a hinge. The inner cavity of the test bucket 3 is provided with a clamping assembly 5 for stable testing. The clamping assembly 5 includes a clamping plate 501 and a cylinder 502. The two clamping plates 501 are set in the inner cavity of the test bucket 3. One side of the clamping plate 501 is fixedly connected to the cylinder 502, and one side of the cylinder 502 is fixedly connected to the inner wall of the test bucket 3.

[0024] Both sides of the clamping plate 501 are connected to sliding sleeves 503. A stabilizing rod 504 is fitted inside the sliding sleeve 503. Both sides of the stabilizing rod 504 are fixedly connected to the inner wall of the test barrel 3. A buffer spring 505 is fixedly connected to one side of the clamping plate 501. A buffer plate 506 is fixedly connected to one side of the buffer spring 505. One side of the buffer plate 506 is in close contact with the automotive parts. An inflation gauge 6 is fixedly connected to one side of the positioning plate 2. An inflation pipe 7 is connected to one side of the inflation gauge 6 via a flange. One side of the inflation pipe 7 is placed inside the test barrel 3. An observation gauge 8 for displaying the pressure inside the test barrel 3 is fixedly connected to one side of the positioning plate 2. A sealing ring 9 is fixedly connected to the top of the test barrel 3, and the surface of the sealing ring 9 is in contact with the sealing cap 4. First, a specified amount of water is injected into the test barrel 3. Because the test barrel 3 is made of transparent material, it is easy to observe the status of the internal automotive parts in real time. After placing the automotive parts into the inner cavity of the test barrel 3, the start... The cylinder 502 extends and retracts, causing the clamping plate 501 to move relative to it. Simultaneously, the sliding sleeve 503 slides smoothly along the surface of the stabilizer bar 504, ensuring stable clamping. As the clamping plate 501 moves, the buffer plate 506 first contacts the automotive parts, forming an elastic buffer clamp with the buffer spring 505. This not only securely fixes the parts but also prevents damage caused by excessive clamping force. After clamping and positioning, the sealing cover 4 is closed by the hinge, ensuring a tight fit with the sealing ring 9 and enhancing the sealing performance of the test barrel 3. Then, the inflation gauge 6 is activated, and gas is delivered to the inner cavity of the test barrel 3 through the inflation pipe 7, creating a stable air pressure inside the barrel. This is used to test the water pressure sealing performance of the automotive parts. During the test, the air pressure value inside the barrel is displayed in real time by the gauge 8, effectively preventing damage to the test barrel 3 due to excessive air pressure. This system achieves precise clamping and positioning of automotive parts and ensures the smooth progress of the water pressure sealing test, guaranteeing accurate and reliable test results.

[0025] A light 10 is fixedly connected to the bottom of one side of the positioning plate 2 to facilitate observation of the internal state of the test barrel 3; the light 10 can be used to illuminate the inside of the test barrel 3 and improve the observation effect of the automotive parts inside the test barrel 3.

[0026] Working principle: First, a specified amount of water is injected into the test tank 3. Since the test tank 3 is made of transparent material, it is easy to observe the condition of the internal automotive parts in real time. After the automotive parts are placed into the inner cavity of the test tank 3, the cylinder 502 is activated. Its extension and retraction movement causes the clamping plate 501 to move relative to the test tank. At the same time, the sliding sleeve 503 slides smoothly along the surface of the stabilizer bar 504 to ensure stable clamping. As the clamping plate 501 moves, the buffer plate 506 contacts the automotive parts first, and together with the buffer spring 505, it forms an elastic buffer clamping, which can both firmly fix the parts and prevent excessive clamping force. To prevent damage, after clamping and positioning, the sealing cover 4 is closed with the hinge to ensure a tight fit with the sealing ring 9, enhancing the sealing performance of the test barrel 3. Then, the inflation gauge 6 is activated, and gas is delivered to the inner cavity of the test barrel 3 through the inflation pipe 7 to create a stable air pressure inside the barrel. This is used to test the water pressure sealing performance of automotive parts. During the test, the air pressure value inside the barrel is displayed in real time by the gauge 8, which can effectively prevent damage to the test barrel 3 due to excessive air pressure. This method can achieve precise clamping and positioning of automotive parts and ensure the smooth progress of the water pressure sealing test, ensuring accurate and reliable test results.
