Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of engine, especially a cylinder cover air tightness detection device. BACKGROUND

[0002] The engine cylinder cover is an important part of the engine, located at the top of the engine, connected with the cylinder body. The main function of the cylinder cover is to fix the valve, oil valve and spark plug and other parts, and provide necessary structural support for them. At the same time, the cylinder cover is usually provided with cooling water channel and fuel injection port, etc. in order to cool and fuel supply for the engine. If the cylinder cover is not sealed well, it will cause gas leakage, so that air and fuel leak from where they should not enter or escape, resulting in incomplete combustion and energy waste. Through air tightness detection, these problems can be found and repaired in time, so as to improve the combustion efficiency of the engine.

[0003] Through the search, the Chinese patent with publication number CN219015570U discloses an engine cylinder cover airway air tightness detection device. After the production of the engine cylinder cover is completed, the weight is heavy, and the engine cylinder cover needs to be lifted to the inside of the air tightness detection device manually, which is easy to cause the air tightness detection device to be unable to align with the engine cylinder cover, so as to cause gas leakage. Therefore, the engine cylinder cover is placed into the top of the belt transmission structure through the cylinder cover support structure, and then the belt transmission structure drives the engine cylinder cover to move to the top of the cylinder cover support structure. The cylinder cover structure pushes the engine cylinder cover to move upward and adhere to the inflation structure. The inflation structure inflates the airway in the engine cylinder cover. The air pressure detector detects the air pressure in the airway to determine the sealing strength of the inside of the engine cylinder cover.

[0004] When the above-mentioned cylinder cover tightness is detected, the cylinder cover is moved to the top of the support structure. In the prior art, when the connecting pipeline of the air tightness detector is connected with the reserved hole on the top surface of the engine cylinder cover, because only the connecting pipeline is inserted into the inside of the reserved hole, the connection between the connecting pipeline and the reserved hole is not tight, which causes the connecting pipeline to fall off from the reserved hole during the air tightness detection inflation process due to the slight vibration force generated during inflation, thereby reducing the quality and precision of the air tightness detection of the engine cylinder cover and reducing the detection efficiency.
