Abstract

The invention belongs to the technical field of cylinder cover detection equipment, and provides a cylinder cover dry-type air tightness detection device. The device comprises a rack, a roller way conveying line driven by a driving device is arranged on the rack, and a guide slideway and a sensor for realizing cylinder cover position detection are arranged on the roller way conveying line; a positioning stop block driven by a first cylinder and a lower sealing plate driven by a hydraulic cylinder are arranged at the bottom of the rack; an upper sealing plate is installed at the top of the rack, the two ends of the upper sealing plate are provided with side sealing plates which are driven by a second air cylinder respectively, the clamping faces of the lower sealing plate, the upper sealingplate and the side sealing plates are provided with sealing rings corresponding to cylinder cover holes in position, and the clamping face of the sealing plate on one side is provided with an air tightness detection hole communicated with an air supply device. And an air tightness detector is further mounted at the top of the rack. According to the invention, automatic airtightness detection of the cylinder cover can be realized, the detection efficiency and the detection precision are greatly improved, the leakage amount can be detected, and the tedious process of treatment after immersion of a test piece 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-type air tightness detection device. Background technique [0002] The cylinder head is a box-shaped part with a complex structure. It is processed with intake and exhaust valve seat holes, valve guide holes, spark plug installation holes (gasoline engine) or fuel injector installation holes, etc. There are also water jackets, The intake and exhaust passages and the combustion chamber or part of the 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 action of high-temperature and high-pressure gas. It is a key component. Its structure is relatively complex and requires high precision. Processing The process is complicated, and its processing quality directly affects...
