Description

Technical Field

[0001] The utility model belongs to the technical field of turbochargers, and in particular relates to a precision grinding and processing device for an intermediate housing of a turbocharger. 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. The turbine in turn drives the coaxial impeller, which 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. The corresponding increase in fuel volume and adjustment of the engine speed can increase the engine's output power. When the intermediate housing of the turbocharger is produced, it is often necessary to use a grinding device to grind it.

[0003] Prior art, patent application number: 202221105912.1 discloses a precision grinding device for the intermediate housing of a turbocharger. Through the setting of an adjustment groove, an electric slideway and a driven slideway, when a user uses the grinding device, the user can realize the rotation adjustment of the electric slideway and the driven slideway through the annular adjustment groove. At the same time, the electric slideway and the driven slideway can cooperate with the electric slider and the driven slider respectively to make the rotating plate rotate, thereby solving the problem of frequent disassembly of the housing assembly when processing the curved surface structure to a certain extent, thereby greatly improving the applicability of the entire grinding device. Through the setting of the sliding groove and the bonding strip, when the user uses the grinding device, the user can adjust the distance between the mounting plate and the grinding knife by controlling the position of the mounting plate inside the sliding groove. At the same time, through the setting of the bonding strip, the mounting plate can be prevented from being separated when rotating, thereby improving the service life of the entire precision grinding device to a certain extent.
