The invention discloses an automatic
crawling device for
magnetic powder detection by cross
magnet yoke method. The device comprises a fixing frame, a flaw
detector, a spraying mechanism, a driving mechanism and a control box, the flaw
detector and the control box are fixedly connected to the upper surface of the fixing frame, the spraying mechanism is fixedly connected to the left end and the right end of the fixing frame respectively, and the driving mechanism is arranged at the bottom of the fixing frame, a guide sliding sleeve is fixedly connected to the left side of the fixing frame, the spraying mechanism comprises a pump body, a box body and an atomizing
nozzle, and the driving mechanism comprises guide rods, guide racks, driving gears and
servo motors which are distributed on the two sides of the fixing frame. The driving mechanism and the spraying mechanism are fixedly connected to the surface of the fixing frame, the
servo motors and the pump body are controlled in cooperation with a
numerical control box, the fixing frame can conveniently and automatically move along the guide rods, magnetic suspension can be automatically and evenly sprayed, the number of participants in the detection process is reduced, the requirement on the operation experience of detection personnel in the detection process is reduced, and the detection precision is greatly improved.
