Problems solved by technology

[0003] After the cylinder head is manufactured, the airtightness of the cylinder head needs to be tested. The existing airtightness detection method is to use a blower to blow out the powder and adhere to the inner wall of the cylinder head, and then inject water into the cylinder head hole. Leakage detection, and then quickly and intuitively judge whether there is a leak in the cylinder head by observing the color change of the inner wall of the cylinder head, and the specific location of the leak. The cost is high, and the powder is sprayed into the inner wall of the cylinder head, and it is difficult to clean the powder on the inner wall of the cylinder head later, and this detection method can only judge whether there is a leak point in the cylinder head and the specific location of the leak point, and cannot judge the leakage of the cylinder head Leakage

Abstract

The invention relates to the technical field of cylinder cover detection, in particular to a cylinder cover leakage visual detection device which comprises a bottom supporting plate, a guide supporting frame, a cylinder cover sealing limiting component, a cylinder cover leakage detection component and the like. A guide supporting frame is fixedly installed on the top face of the bottom supporting plate, the air cylinder cover sealing limiting component is arranged on the guide supporting frame, and an air cylinder cover leakage detecting component is fixedly installed on the top face of the bottom supporting plate. High-pressure gas is conveyed into the cylinder cover, so that the high-pressure gas pushes all the movable pipes and the rolling balls to move upwards, a worker can judge whether the cylinder cover leaks gas or not by observing whether the height positions of the rolling balls are consistent or not, then the gas tightness of the cylinder cover is judged, and meanwhile the specific position of a leakage point can be deduced according to the position of the rolling ball.

Description

technical field [0001] The invention relates to the technical field of cylinder head detection, in particular to a visual detection device for cylinder head leakage. Background technique [0002] The engine cylinder head, cylinder liner and piston together form the combustion chamber of the diesel engine, which is one of the parts of the diesel engine that withstands high temperature and high pressure working conditions. The inner cavity of the cylinder head is arranged with intake ports, exhaust ports, intake valves, exhaust Doors, fuel injectors, etc., the cylinder head is often in contact with high-temperature and high-pressure gas, so the bottom surface of the cylinder head needs to bear a large heat load and high-pressure gas pressure generated by fuel combustion. When the engine is working, the cooling water installed in the cylinder head The cavity communicates with the cooling water hole of the cylinder block, and the combustion chamber is cooled by the cooling water...
