The magnetic source of the utility model is formed by that a permanent magnet is inlaid in the middle part of a magnetic conductor, and the outer sleeve of the magnetic source is provided with a lifting handle and symmetrically provided with pincers shaped pole shoes. The side port of the outer sleeve is fixedly provided with a steering wheel with a rotary handle, and a recess on the end part of the steering wheel is matched with the magnetic source. The rotary disk and the lifting handle are connected by a spring and the handle, and thus, a portable single-hand flaw detector for the permanent magnetic powder which is suitable for high-altitude, underground and field site detection is formed.
Description
The utility model relates to a kind of industrial nondestructive testing instrument, particularly utilizes permanent magnetic field that detected workpiece is carried out magnetized magnetic powder inspection instrument field.
Magnetic powder inspection is one of conventional method of Non-Destructive Testing, and electromagnetic type and magneto are arranged.Electromagnetic type equipment heaviness promptly will have power supply, and the live wire traction is very inconvenient again, is unsuitable for field work.Magneto does not need power supply, and volume is little, and is in light weight easy to carry.The magneto magnetic powder flaw detector operation of using at present is easy not enough, kind is single, can not be applicable to the complicated workpiece flaw detection in various working environments and surface with as: No. 89221644.1, Chinese patent, the October 10 nineteen ninety day for announcing, exercise question: magneto magnetic powder flaw detector, it is by Nd-Fe-B permanent magnet, magnetic conductive cover, and yoke and magnetic conductive round roller are formed.On magnetic conductive round roller, two magnetic conductive covers are arranged by the binding of magnetic conduction connecting piece, be fixed with the non-magnetic conduction bar of relative twice body on the magnetic conductive cover, rotating Nd-Fe-B permanent magnet is housed in the magnetic conductive cover, the bottom of body is fixed with two arc-shaped guide rails, yoke is plugged on the guide rail, adjust distance and the position of yoke on guide rail between two magnetic conductive covers during use, hold magnetic conductive round roller.Two yokes are closely contacted with workpiece, turn knob and make permanent magnet pole vertical with workpiece, then workpiece is applied in a very strong permanent magnetic field, press the conventional method flaw detection of magnetic flaw detection then, flaw detection finishes, with 90 ° of knob, then the external magnetic field of workpiece disappears, and takes off workpiece.This utility model can not detect the surface of the work complicated shape, and it is closely to contact with workpiece with two yokes in addition, simultaneously can not realize one-handed performance, and two yokes are on the workpiece on the same surface level when being difficult for realizing detecting.
The purpose of this utility model is to overcome the weak point of above-mentioned prior art, in order to realize the instrument one-handed performance, be suitable for the high-altitude, underground, field condition detects, for the ease of detecting a flaw on the workplace that carries out multiple complexity, with be easy to carry about with one and move, thereby providing a kind of is embedded in magnetic conductor middle part by block permanent magnet and forms magnetic source, its outside cover one magnetic conductor overcoat, put two symmetric windows outward and be embedded in non-magnetizer, fix a handle in the overcoat side, two pole shoes that have moving boots inject a non-magnet material steering wheel that has swing handle in the overcoat side ports, and steering wheel has a groove and magnetic source to match; Swing handle connects with handgrip, and handgrip is connected on the handle, and spring is associated between handle and the handgrip, the one-handed performance type permanent magnetic powder defectoscope of composition.
The utility model mainly is made up of steering wheel, spring, the handle of magnetic source, the overcoat that has two pole shoes, moving boots, band swing handle.Be elaborated below in conjunction with accompanying drawing, Fig. 1 is an one-handed performance type permanent magnetic powder defectoscope structural representation.
