Automatic crawling device for magnetic powder detection by cross magnet yoke method

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to an automatic crawling device for cross-yoke magnetic powder detection. Background technique [0002] Magnetic particle testing is the most effective means to detect surface and near-surface defects of ferromagnetic materials, and in magnetic particle testing, the cross yoke method is the most commonly used testing method. The crossed yoke method can detect very small defects, because the direction of the magnetic field is perpendicular to the direction of defect extension in each cycle of the magnetization cycle, so one-time magnetization can detect defects in any direction on the workpiece surface, and the detection efficiency is high. [0003] At present, in the existing technology, many people are required to cooperate in the process of cross-yoke magnetic particle detection. Due to the existence of large human factors, it is easy to lead to low detection accuracy, a...
