Description

Technical Field

[0001] The utility model relates to the technical field of magnetic particle flaw detection, in particular to an automatic magnetic suspension spraying device for magnetic particle detection. Background Art

[0002] Magnetic particle inspection relies on magnetic powder gathering in the leakage magnetic field to form magnetic traces to show defects. The degree of magnetic traces is not only related to the nature of the defect, the degree of magnetization, the method of applying the magnetic powder and the surface state of the workpiece, but also to the properties of the magnetic powder itself, such as magnetism, particle size, shape, density, activity and recognition. The magnetic suspension, which is made by mixing magnetic powder and dispersant in a certain proportion, is sprayed on the surface of the magnetized workpiece to detect the defects of the workpiece.

[0003] At present, magnetic suspension spraying cannot achieve a comprehensive spraying effect in one go. It requires multiple flipping and changing of angles to achieve a comprehensive effect. In addition, most of the processes require workers to operate, which increases the labor of the staff and reduces the spraying efficiency of the magnetic suspension. Utility Model Content

An adjusting screw 64 is horizontally sleeved in the spring 63. The outer end of the adjusting screw 64 penetrates the threaded groove and is connected to the side end of the horizontal frame 61 by rotation and extends to the outside. The adjusting screw 64 is rotated at the side end of the horizontal frame 61, so that the inner end of the adjusting screw 64 always ensures that the end face of the clamping plate 62 is in contact with the adjusting screw under the elastic expansion and contraction of the spring 63. 64 are abutted against each other, thereby realizing the movement of two relatively distributed clamping plates 62 toward or away from each other, meeting the clamping operation requirements of workpieces of various specifications. A motor support seat 7 is installed on the outer end surface of one side bracket 3, and a rotating motor 8 is installed on the motor support seat 7. The output shaft of the rotating motor 8 is fixedly connected with a bolt on one side end of the horizontal roller 5. The horizontal roller 5 connected to the end of its output shaft is driven by the rotating motor 8 to rotate on the inner wall of the horizontal cylinder 4.
