Abstract

The invention belongs to the technical field of cylinder head detection equipment, and provides a cylinder head dry air tightness detection device, comprising a frame, a roller conveying line driven by a driving device is arranged on the frame, and a guide is provided on the roller conveying line A slideway and a sensor for detecting the position of the cylinder head; the bottom of the frame is provided with a positioning block driven by a first cylinder and a lower sealing plate driven by a hydraulic cylinder; an upper sealing plate is installed on the top of the frame, and both ends of the upper sealing plate are respectively There is a side sealing plate driven by the second cylinder, the clamping surfaces of the lower sealing plate, the upper sealing plate and the side sealing plate are all provided with sealing rings corresponding to the positions of the cylinder head holes, and the clamping surface of one of the sealing plates is The upper part is provided with an air tightness detection hole which is communicated with the air supply device, and an air tightness detector is also installed on the top of the rack. The invention can realize the automatic air tightness detection of the cylinder head, not only the detection efficiency and detection accuracy are greatly improved, but also the size of the leakage can be detected, and the tedious process of post-treatment of the test piece after soaking in water is omitted.

Description

technical field [0001] The invention relates to the technical field of cylinder head detection equipment, in particular to a cylinder head dry air tightness detection device. Background technique [0002] The cylinder head is a box-shaped part with a complex structure. It is machined with inlet and exhaust valve seat holes, valve guide holes, spark plug installation holes (gasoline engine) or injector installation holes, etc. Intake and exhaust port and combustion chamber or part of combustion chamber. The cylinder head is the installation base of the valve mechanism and the sealing cover of the cylinder. Its function is to seal the cylinder, form a combustion space with the piston, and withstand the effect of high temperature and high pressure gas. It is a key component. The process is complex, and its processing quality directly affects the overall performance of the engine. [0003] After the cylinder head is processed, the air-tightness test of the cooling water cavity...
