TECHNICAL FIELD

[0001] The application belongs to the technical field of sealing detection of automobile water tanks, and specifically relates to a water detection machine. BACKGROUND

[0002] The automobile water tank, also known as a coolant tank, is an important component of the automobile cooling system. Its main function is to store and circulate engine coolant, helping to regulate engine temperature and prevent overheating. Sealing detection of the automobile water tank is an important step to ensure the normal operation of the vehicle cooling system, which can prevent coolant leakage and thus protect the engine from overheating damage.

[0003] Under normal circumstances, compressed air needs to be injected into the automobile water tank during detection, and a set pressure needs to be applied. The automobile water tank is placed in a water tank, and whether bubbles are emitted from the product is observed. However, due to the effect of buoyancy, the automobile water tank will float up in the water tank, and the operator needs to continuously press to ensure that the automobile water tank is completely immersed in the water tank.

[0004] In order to solve this problem, CN106595970A discloses a gas tightness testing device, which solves the defects of poor operability and inaccurate observation results of the existing automobile part gas tightness test by manual immersion.

However, the specific connection method of the pressure cover is not disclosed in the above technical solution. For the pressure cover disclosed in the above technical solution, although the product can be prevented from floating up, the product still needs to be manually pressed into the water tank during installation. During detection, the product needs to be connected to the external air supply equipment, compressed air needs to be injected into the product and stabilized, the rod-shaped structure cannot well adapt to the structure of the surface of the product and the air supply pipeline connected to the product, and the rod-shaped pressure cover and the product are in hard contact, which causes damage to the product.
