Description

Technical Field

[0001] The utility model relates to the technical field of turbochargers, and particularly to a grinding wheel grinding device for a turbocharger housing. Background Technique

[0002] A turbocharger is actually an air compressor that increases the intake air volume by compressing air. It uses the inertia of the exhaust gas discharged from the engine to push the turbine in the turbine chamber, and the turbine drives the coaxial impeller. The impeller pressurizes the air sent from the air filter pipeline and makes it enter the cylinder after pressurization. When the engine speed increases, the exhaust gas discharge speed and the turbine speed increase synchronously, and the impeller compresses more air into the cylinder. The increase in air pressure and density allows more fuel to be burned, correspondingly increasing the fuel quantity and adjusting the engine speed, thereby increasing the output power of the engine. During the processing of the turbocharger housing, a grinding wheel machine is required to perform grinding processing on it.

[0003] After retrieval, the utility model patent with the publication number of CN207255905U discloses a processing device for producing a turbocharger compressor housing, including a processing housing. A support device and a grinding device are arranged in the processing housing. The support device includes a chassis seat and a motor. The motor is fixedly arranged at the bottom of the processing housing, and the output shaft of the motor is provided with a chassis seat. A plurality of support seats are arranged on the chassis seat. A screw rod with an external thread is arranged on the chassis seat. One end of the screw rod with an external thread is fixedly arranged on the chassis seat, and a plurality of pressing blocks are movably arranged on the screw rod with an external thread. The grinding device includes a grinding frame. The grinding frame is slidably arranged in the processing housing, and a grinding wheel sheet seat is slidably arranged on the grinding frame. A grinding wheel machine is arranged on the grinding wheel sheet seat. This patent has the advantages of being able to effectively clamp during the processing of the turbocharger compressor housing, being compatible with the processing of turbocharger compressor housings of different sizes, and being convenient and fast to adjust during use.

[0004] However, the above patent has the following deficiencies: The position of the grinding wheel machine on the grinding frame is fixed, which is not convenient for contacting different positions of the turbocharger compressor housing, thus affecting the grinding process. And waste chips will be generated during grinding. If not collected, it is easy to accumulate in the inner cavity of the processing housing, which is not convenient for further cleaning. For this reason, we propose a grinding wheel grinding device for a turbocharger housing. Content of the Utility Model
