Seal ring drop detection tooling for turbochargers

Abstract

The invention discloses a sealing ring drop detection tool for a turbocharger, which includes an intermediate body and a component formed by a turbine shaft body, and the turbine shaft body and the shaft hole of the intermediate body are assembled and connected by two upper and lower sealing rings Together, the detection tool includes a positioning seat for placing the intermediate, a lifting platform and a detector. There is a cavity in the middle of the positioning seat, and a clamping mechanism is provided on the lifting platform. The lifting platform is used to drive the clamping mechanism to move Move the turbine shaft downward for a certain distance to realize the exposure of the lower sealing ring; the detector is set outside the lower part of the positioning seat to realize the detection of the exposed lower sealing ring; when detecting, the exposed length of the lower sealing ring is less than or equal to the lower sealing ring The height of the ring. The invention provides a sealing ring for a turbocharger that detects the sealing ring between the turbine shaft body and the intermediate body to determine whether the sealing ring is dropped, thereby ensuring the effect of increasing the maximum power of the turbocharger Drop detection tooling.

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
