[0001] The present application relates to the technical field of turbocharger production, and in particular to a press-in device for a turbocharger compression shell air nozzle. Background Art

[0002] A turbocharger is a type of air compressor that increases the amount of air intake by compressing air. The inertial force of the exhaust gas discharged by the engine pushes the turbine in the turbine chamber, and the turbine drives the impeller coaxially connected to it to rotate. The impeller presses the air delivered by the air filter duct and pressurizes it into the cylinder. When the engine speed increases, the exhaust gas discharge speed increases synchronously with the turbine speed, and more air enters the cylinder under the compression of the impeller, so the output power of the engine increases. The compression shell is a common workpiece in industrial production. The alloy raw materials are proportioned, smelted, refined, deslagging and cast. It is usually necessary to open an exhaust hole on the formed compression shell and install a corresponding L-shaped air nozzle on the exhaust hole.
