The company has developed an automatic image capturing magnetic particle flaw detector for train axles, including a dark room, in which a suspension and a magnetic particle flaw detection body are set; The magnetic particle flaw detection body includes magnetic suspension spray mechanism, open and close electromagnetic coil, linear guide rail, workpiece fixture, rotary drive mechanism and linear drive mechanism; The opening and closing electromagnetic coil is installed on the sliding block; The workpiece clamp is used to hold the workpiece, and the workpiece is sleeved in the open and close electromagnetic coil during flaw detection; The rotary drive mechanism is used to drive the workpiece to rotate, and the linear drive mechanism is used to drive the open and close electromagnetic coil to move along the linear guide rail; The suspension is provided with an image capturing mechanism arranged in a straight line, and two parallel ultraviolet illumination lines are symmetrically arranged on both sides of the straight line. The automatic image capturing magnetic particle flaw detector of the train axle provided by the invention can facilitate the operator to judge whether the workpiece has defects outside the dark room, and avoid the operator from working for a long time under the condition of ultraviolet light.
