Complex curved surface integrity defect detection device and method

The invention belongs to the technical field of product detection, and particularly relates to a complex curved surface integrity defect detection device and method.The complex curved surface integrity defect detection device comprises a detection equipment rack and a curved surface part, and a first mechanical arm and a second mechanical arm are arranged on the two sides of the interior of the detection equipment rack correspondingly; a spraying mechanism used for spraying magnetic fluid containing fluorescent liquid to the surface of the curved surface part is assembled at the top of the interior of the detection equipment rack, and a welding seam tracking and magnetizing mechanism used for guiding the magnetic fluid to go deep into the surface defect of the curved surface part is assembled at the output tail end of the second mechanical arm. A liquid falling groove is formed in the surface of the detection equipment rack in an embedded mode, visual detection equipment is arranged at one end of the back of
