Abstract

The invention relates to airtightness detection equipment for an engine cylinder block, in particular to a sounding body leak detection device, which comprises a frame, a sealing mechanism, an air intake mechanism, an air pump and a detection mechanism, wherein the sealing mechanism comprises an upper sealing cover, a lower sealing box and a compression cylinder, the lower sealing box is a box body which can accommodate the cylinder block and with an opening at the upper end, the lower sealing box is fixed on the frame, the upper sealing cover is in the shape of circular truncated cone with a large upper part and a small lower part, the lower end surface of the upper sealing cover is connected with an opening at the upper end of a cavity of the cylinder block in a sealed manner, the other end of an air intake pipe is communicated with an inner cavity, a pressure release valve is communicated with the inner cavity, the detection mechanism comprises a sounding body, a sounding cavity and a sounding port are formed in the sounding body, the sounding cavity is communicated with an outer cavity of the lower sealing box and the sounding port, and the sounding port is provided with a sounding reed. The sounding body leak detection device is an efficient airtightness detection device provided for solving the problem that the efficiency of the existing cylinder block airtightness detection is too low.

Description

technical field [0001] The invention relates to an air tightness testing device for an engine cylinder block, in particular to a leak testing device for a sounding body. Background technique [0002] The engine cylinder block is an essential part in the structure of the engine, and its production has also entered the era of mass production. Engine cylinders are molded by casting and then machined to form products. Defects such as air shrinkage cavities and cracks sometimes occur during the casting process. These defects easily lead to problems such as oil leakage and oil leakage, which seriously affect the performance of the engine; the most common problems are the lack of engine power and high fuel consumption. Therefore, in the manufacturing process of the cylinder block, the air tightness of the cylinder block must be tested. [0003] The current air tightness test is usually carried out manually, that is, the closed engine cylinder is immersed in water, the cylindrical...
