Description

Air tightness detection device for turbocharger shell Technical Field The utility model relates to the technical field of turbocharger shells, in particular to an air tightness detection device for a turbocharger shell. Background Turbochargers are actually air compressors that increase the amount of intake air by compressing the air. The method mainly uses the inertia of the exhaust gas discharged by the engine to drive the turbine in the turbine chamber, the turbine drives the coaxial impeller, the impeller presses the air sent by the air filter pipeline to boost the air into the air, however, when the turbocharger shell is reproduced, the air tightness detection is usually needed to detect whether the turbocharger shell is qualified or not, however, the existing airtight detection device is single in structure, is inconvenient to detach the turbocharger shell rapidly, reduces detection efficiency, does not have a limiting function during detection, causes detection errors, and is designed for the problem. The utility model provides a turbocharger housing gas tightness detection device, including transparent material's shell body, install lower end cap and last end cap that sets up in opposite directions in the shell body inner chamber, the axis of lower end cap and last end cap is the collineation setting, one side of lower end cap and last end cap is equipped with two side plugs, the inside of lower end cap, go up end cap and side plug all is equipped with the recess, the gasket that plays the sealing function is installed respectively to the inside of recess, lower end cap fixed mounting is at the top of hollow shaft, the inner chamber of hollow shaft is linked together with the recess of lower end cap, go up the end cap and install the head at vertical pneumatic cylinder, install gas pressure sensor in the recess of last end cap. The air tightness detection device provided by the utility model can realize automatic positioning and firm compaction of the turbocharger shell in the air tightness detection process, and the air leakage position of the shell can be conveniently judged.
