This equipment is designed according to the requirements for magnetic particle inspection of locomotive bearing rings. It is a fixed and semi-automatic equipment. The continuous composite magnetization method is adopted, and the beat is controlled by a programmable controller to detect defects such as cracks and slag inclusion caused by forging, quenching and grinding, fatigue and the like on the inner and outer rings of the bus bearing, the outer ring surface of the truck bearing and the near surface. The equipment adopts the rod penetrating method and the U-shaped yoke method to carry out omnidirectional composite magnetization on the workpiece. When the workpiece is magnetized, it does not contact with the workpiece, which belongs to non-contact type. The equipment can complete the processes of rod threading, spraying, magnetizing, rotating observation, demagnetization and the like by once feeding, and can be operated manually or automatically according to work requirements, thus being convenient to use. It has the characteristics of simple operation, high flaw detection efficiency, safety, reliability, low labor intensity of workers, etc.
