Abstract

The invention relates to a leak detecting device of an automotive brake liquid storage pot and a leak detecting method of the leak detecting device, and belongs to the technical field of hydraulic container leak detection testing. The leak detecting device comprises a base, a support, a leak detecting clamp, the liquid storage pot, a pressing structure, a sealing and blocking structure and a testing structure. A liquid level sensor fixing hole is transversely formed in the middle of a lower body, two bottom oil outlets are formed in the lower portion of the lower body, and two oil outlet choke plugs are arranged at the positions, corresponding to the two bottom oil outlets of the liquid storage pot, of the leak detecting clamp. The leak detecting device further comprises a plug pin fixing structure and an identification structure, the plug pin fixing structure is arranged behind the liquid storage pot and comprises a side fixing air cylinder and a plug pin, the plug pin is arranged at the front end of the side fixing air cylinder and arranged opposite to the liquid level sensor fixing hole, and when the side fixing air cylinder moves, the plug pin can be connected with the liquid level sensor fixing hole in an inserting mode after moving forwards. The leak detecting device of the automotive brake liquid storage pot further comprises the leak detecting method. The leak detecting device of the automotive brake liquid storage pot and the leak detecting method of the leak detecting device have the advantages that leak detection does not exist, the yield of products is improved, and the potential quality hazard of an automobile brake failure caused by the products is avoided.

Description

technical field [0001] The invention relates to a leak detection device and a leak detection method for a liquid storage tank, in particular to a leak detection device and a leak detection method for an automobile brake liquid storage tank, and belongs to the technical field of hydraulic container leak detection testing. Background technique [0002] Automobile brake fluid storage tank is one of the important components of automobile vacuum booster braking system. The brake pedal converts mechanical energy into hydraulic energy through the push rod and master cylinder piston, so that the hydraulic energy is transmitted to the brake through the pipeline. Wheel cylinder, so that the master cylinder brake fluid flows into the wheel cylinder under a certain pressure, and the piston of the two-wheel cylinder pushes the brake shoe to rotate around the support pin, and the upper end is separated to both sides and pressed against the inner part of the brake drum with its friction pla...
