Bearing rotor flaw detector

The invention relates to the technical field of bearing rotor detection, and particularly discloses a bearing rotor diagnostic machine which comprises a base, a machine table is fixedly mounted at the top of the base, a rack is fixedly mounted at the top of the machine table, a detection device is fixedly mounted at the rear end of the inner side of the rack, and a positioning device is fixedly mounted on the front side of the top of the rack. According to the device, two different detection methods of the magnetic sensor and ultrasonic detection are combined, the bearing and rotor parts can be comprehensively and comprehensively detected on different layers, the detection comprehensiveness and accuracy are improved, the magnetic sensor is mainly used for detecting surface defects and cracks, the ultrasonic detection is mainly used for detecting internal defects, and the detection accuracy is improved. The two are combined for use and can complement each other, the detection reliability and accuracy are impro
