Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of turbocharger component processing equipment, and more specifically, to a surface grinder for processing turbocharger components. Background Technology
[0002] A turbocharger is essentially an air compressor that increases the intake air volume by compressing air. During operation, the inertial force of the exhaust gases from the engine drives a turbine within the turbine housing. This turbine, in turn, drives a coaxial impeller, which compresses the air supplied through the air filter and forces it into the cylinders. As engine speed increases, the exhaust gas velocity and turbine speed also increase simultaneously. The impeller then compresses even more air into the cylinders. The increased air pressure and density allow for the combustion of more fuel. By increasing the amount of fuel supplied and adjusting the engine speed, the engine's output power can be increased.
[0003] In the process of turbocharger manufacturing, grinding machines are needed to process turbocharger components. Among them, the impeller is one of the key components of the turbocharger. After casting, the end face of the impeller needs to be machined to be horizontal using a grinding machine. However, some impellers are not easy to clamp and fix, and it is not easy to process multiple impellers at one time. It is also not easy to collect the waste chips raised during grinding. Therefore, we propose a surface grinder for turbocharger component processing. Utility Model Content

[0026] It should be noted that this utility model is a surface grinder for processing turbocharger parts. In use, firstly, the supporting iron plate 3 is electromagnetically attached to the electromagnetic chuck 2, and the turbocharger impeller is fitted onto the outside of the limiting post 5, so that the large outer diameter end of the impeller contacts the bottom surface of the bearing plate 4, allowing the limiting post 5 to pass through the mounting hole in the middle of the impeller. Then, the three-way solenoid valve 16 is activated to connect the output end of the air pump 14 to the hose 17. The air pump 14 is activated to introduce external air from the hose 17, air distribution pipe 18, air injection pipe 19, air guide hole 7, through hole 9, air guide groove 8, and air extraction pipe 11 into the inner cavity of the annular airbag 10. At this time, the annular airbag 10 expands, compressing and fixing the inner wall of the mounting hole in the middle of the impeller, thereby stably fixing the impeller on the bearing plate 4. Then, the grinding wheel on the grinding machine 1 is used to grind the top of the impeller, while the dust extraction fan 21 is activated simultaneously. The suction pipe 23 and the dust hood 24 generate suction. The suction of the dust hood 24 is used to draw the dust raised during grinding into the inner cavity of the dust collection bag 27. Finally, after grinding the small outer diameter end of the impeller, the three-way electric control valve 16 is activated to connect the input end of the air pump 15 to the end of the hose 17. The air pump 15 is then activated to draw away the gas in the inner cavity of the annular air bag 10, releasing the impeller from its fixation. The impeller is then flipped so that the small outer diameter end of the impeller contacts the top surface of the supporting iron plate 3. The annular air bag 10 is then used to fix the impeller again so that the large outer diameter end of the impeller can be ground.
