Aluminum alloy rotor machining device for main machine of screw compressor

The utility model discloses an aluminum alloy rotor processing device for a main engine of a screw compressor, which relates to the technical field of rotor processing equipment, and is characterized by comprising a base provided with a fixing block for fixing a rotor and a polishing structure for processing and polishing the rotor, the fixing block is provided with a vibration reduction structure used for weakening vibration of the drill. The machining device further comprises a power source used for driving the rotor to rotate. According to the device, the motor and the machining structure are separated, vibration caused by the motor can be greatly weakened, meanwhile, the vibration reduction structure is arranged between the motor and the rotor, vibration transmitted to the rotor by the motor is further weakened, the grinding quality is improved, and the grinding structure of the device can be suitable for rotors of different sizes; and the practicability of the device is improved. 本实用新型公开了一种螺杆压缩机主机用铝合金转子加
