Air tightness test device

Abstract

The invention relates to an air tightness test device, and a defect that an existing auto component air tightness test is carried out through a mode of manual submersion, the controllability is poor, and an observation result is no accurate is solved. The air tightness test device comprises a water tank and an inflation device connected to a component. The water tank is internally provided with a pressing piece for pressing the component to be submerged, and the upper part of the water tank is provided with a safety box cover which can be opened. The upper part of the water tank is provided with the safety box cover, the safety box cover covers the water tank to form a closed structure to play a role of protection, and an accident in the component test process is prevented. The water tank is internally provided with the pressing piece which presses the component downward to be submerged in water, thus the component is completely submerged, the inflation device inflates the component with air, the bubble condition around the component is observed, thus whether the air tightness of the component is qualified or not is determined, the pressing piece presses the component to be submerged, the controllability is good, the submerged component is stable, and shaking is not generated.

Description

technical field [0001] The invention relates to a test device, in particular to an air tightness test device for testing automobile components. Background technique [0002] All parts of the car will have airtight requirements, such as: fuel tank, radiator cover, cooling module, left / right front and rear combination lamp assembly, left / right daytime running light assembly, left / right rear fog lamp assembly, kettle, Expansion tank assembly, air conditioner high and low pressure pipe assembly, compressor exhaust hose assembly, carbon canister assembly, etc., before assembly, these parts need to pass the air tightness test, and only qualified products can be assembled for practical use. . [0003] Existing parts are tested for air tightness, which is generally carried out by air test at present. Ventilate the part, then immerse the part in water, observe the air bubbles in the water of the ventilated part, and then judge whether the airtightness is qualified. [0004] Howeve...

AI Technical Summary

Problems solved by technology

[0006] The invention solves the defects that the existing auto parts airtightness test is carried out by hand immersion, poor controllability, and inaccurate observation results, and provides an airtightness test device, which adopts pressing and immersing parts The airtightness test of components in water is realized in a unique way, with strong controllability, stable immersion of components, convenient observation and accurate results

[0007] The present invention also solves the defects that the existing air-tightness test is carried out by bare-hand immersion, which has low safety and is prone to safety accidents. There is a safety box cover on the top, and the safety box and the water tank form a closed structure to ensure the safety of the test.

[0008] The invention also solves the defect that the existing airtightness test cannot accurately control the test water depth, and provides an airtightness test device, which can accurately control the immersion depth of parts by adjusting the height of the baffle
