Description

Technical Field

[0001] The utility model relates to the technical field of turbochargers, and in particular to a turbocharger camber polishing device. Background Art

[0002] A turbocharger is actually an air compressor that increases the intake volume by compressing air. It uses the inertial force of the exhaust gas discharged by the engine to drive the turbine in the turbine chamber, and the turbine drives the coaxial impeller. The impeller presses the air sent from the air filter pipe to pressurize it into the cylinder. When the engine speed increases, the exhaust gas discharge speed and the turbine speed also increase synchronously, and the impeller compresses more air into the cylinder. The increase in air pressure and density can burn more fuel, increase the fuel volume and adjust the engine speed accordingly, and increase the engine's output power. When processing the turbocharger housing, it needs to be polished.

[0004] However, the above patents still have the following shortcomings: it is not convenient to grind the outer curved surface of the turbocharger housing, and the practicality is poor; and the waste chips generated by polishing are relatively loose, and the waste chips generated by polishing are easy to be lifted up, and it is not convenient to effectively collect the waste chips by relying on the chip collecting plate. For this reason, we propose a turbocharger curved surface polishing device. Utility Model Content
