Sealing ring falling detection tool for turbocharger

Abstract

The invention discloses a sealing ring falling detection tool for a turbocharger. The detection tool comprises a middle body and an assembly formed by a turbine shaft body, and the turbine shaft bodyand a shaft hole of the middle body are assembled and connected together through an upper sealing ring and a lower sealing ring. The detection tool comprises a positioning seat used for placing the middle body, a lifting table and a detector, a cavity is formed in the middle of the positioning seat, a clamping mechanism is arranged on the lifting table, and the lifting table is used for driving the clamping mechanism to act so that the turbine shaft body can move downwards by a certain distance to expose the lower sealing ring. The detector is arranged on the outer side of the lower part of the positioning seat so as to detect the exposed lower sealing ring. During detection, the exposed length of the lower sealing ring is smaller than or equal to the height of the lower sealing ring. According to the sealing ring falling detection tool for the turbocharger, the sealing ring between the turbine shaft body and the middle body is detected so as to determine whether the sealing ring fallsor not, and then the effect of improving the maximum power of the turbocharger is guaranteed.

Description

technical field [0001] The invention relates to the field of detection tooling, in particular to a sealing ring drop detection tool for a turbocharger. Background technique [0002] In a turbocharger, the connection seal between the turbine shaft body and the intermediate body is very important for improving the maximum power of the turbocharger. However, in the traditional assembly connection between the turbine shaft body and the intermediate body shaft hole, it is easy to cause the turbine If the shaft body and the intermediate body are not matched in place, it is not conducive to the installation of the turbine shaft body and the intermediate body in the turbocharger, and it is easy to cause incomplete sealing connection and insufficient sealing. The unfavorable factors of the maximum power lead to the situation that the maximum power raised is too small. [0003] For this reason, the technical scheme of adopting upper and lower two sealing rings to realize the assembly...

AI Technical Summary

Problems solved by technology

But the problem is that in the actual assembly process, since the upper sealing ring is assembled first, there is a gap between the turbine shaft body and the shaft hole of the intermediate body, so the installation of the upper sealing ring can be guaranteed, but the lower sealing ring is in place. During the assembly process, the sealing ring may fall off, which will lead to a decrease in the performance of the turbocharger
