[0002] At present, the turbocharger is a key technology in modern automobile engines. It increases the air pressure and density entering the engine by utilizing the energy of the exhaust gas discharged from the engine, thereby improving the power output and fuel efficiency of the engine. The turbocharger mainly consists of two parts: a turbine and a compressor. The turbine part includes a turbine and a nozzle ring, and the compressor part includes an impeller, a housing, and a seal. The working principle of the turbocharger is to convert the energy of the exhaust gas into the rotational power of the turbine, which in turn drives the impeller to compress the air and deliver the compressed air into the engine cylinder.

[0003] The shapes of existing worm wheel turbocharger housings are diverse. Especially for cylindrical worm wheel turbochargers, the overall shape requirements are more stringent. In order to ensure the sealing and tightness of the installation, runout detection needs to be performed on both the inside and outside of the worm wheel housing. Usually, the runout detection is carried out on a lathe, but the installation is cumbersome, which is likely to cause surface damage to the turbocharger housing, unable to guarantee the product quality, and there is no corresponding detection device for independent detection.
