Bearing roller magnetic particle flaw detector

The utility model relates to the technical field of magnetic particle inspection, and discloses a bearing roller magnetic particle inspection machine which comprises a rack, a groove body is arranged on the top side of the rack, a rotary driving device is arranged in the groove body, a driving chain wheel is fixedly installed on a motor shaft of the rotary driving device, and a bearing roller is arranged on the driving chain wheel. And a driven chain wheel is rotationally arranged on the other side in the groove body. When the conveying device is used, a workpiece is located between the two corresponding sets of supporting turning rollers, meanwhile, the chain belts operate to convey bearing rollers, when the chain belts operate, the second chain belt located in the middle of the groove body can be driven, then the second chain belt drives the driving wheel, the driving wheel exerts acting force on the supporting head, and therefore the workpiece is driven to rotate.
