Turbocharger middle shell airtightness tester

The invention relates to the technical field of airtightness testers, in particular to a turbocharger middle shell airtightness tester which comprises an operation table base, a control panel is fixedly connected to the right side surface of the operation table base, a mounting base is arranged at the top end of the operation table base, and a first gear is arranged on the upper surface of the operation table base. The bottom end of the first gear is fixedly connected with a first limiting shaft, and the first limiting shaft is installed in the operation table base. And the motor body is mounted at the bottom end of the first limiting shaft. According to the invention, the air tightness problem of the middle shell of the turbocharger can be accurately seen after the installed air bag is bulged, so that the targeted detection can be realized, the unqualified position can be quickly and accurately found out, and the problem that the air tightness cannot be adaptively and accurately detected in the past is solve
