Description

Technical Field

[0001] The utility model relates to the technical field of automobile radiator detection, in particular to an automobile radiator leak-proof detection platform. Background Art

[0002] The car radiator water chamber needs to be tested for air tightness before being assembled to the radiator to prevent air holes in the radiator water chamber during processing, which may cause water leakage in the radiator water chamber. It is usually tested using a leak detection bench.

[0003] For example, a car radiator water chamber sealing detection device with the authorization announcement number CN220084260U is disclosed. The above document sets a baffle and a movable push plate at the side ends of the placement plate respectively. The interaction between the baffle and the push plate enables the radiator water chamber placed on the placement plate to be fixed, thereby preventing the radiator water chamber from floating up when immersed in water, resulting in the radiator water chamber not being fully immersed in water. However, after the existing leak-proof detection bench has completed the air-tightness detection of the car radiator, personnel are required to separate the car radiator after the detection from the connecting end of the air compressor, and at the same time, the car radiator needs to be disassembled from the leak-proof detection bench so that the undetected car radiator can be placed on the leak-proof detection bench and connected. During this process, the air compressor needs to be turned off. At the same time, the time consumed in the process of separating and installing the car radiator is relatively long, and the continuity during the air-tightness detection of the car radiator is relatively poor, resulting in low efficiency in the air-tightness detection of the car radiator.

[0004] At the same time, when the leak-proof test bench in the above-mentioned document is fixing the car radiator, due to the lack of a buffer structure between the contact surface of the fixing plate and the car radiator, the fixing plate exerts a large force on the car radiator when it moves toward the car radiator to fix it, which can easily cause the car radiator to deform and be damaged.
