Abstract

The present invention relates to the technical field of automobile supercharger production, specifically to an automobile supercharger assembly air tightness detection device, including a base, a limit seat for supporting and limiting a turbocharger housing is fixedly installed on the upper end surface of the base, a support column located behind the limit seat is fixedly installed on the upper end surface of the base, and an alignment mechanism is arranged on the support column. An integrated operation model of alignment, external support and internal sealing is adopted to complete the air tightness detection of the turbocharger housing, and high-precision alignment of the seal and the housing is achieved. A triangular connection is used for overall locking before pressurization, and the sealing plate is fixed again from the inside. At the same time, the seal and the housing are tightly fitted by extruding the rubber convex block through internal expansion, thereby greatly improving the rigidity and stability of the entire sealing system, while ensuring that the seal is evenly stressed, effectively reducing stress concentration and gas leakage risks, thereby improving the reliability and efficiency of the detection process and the accuracy of the test results.
