Abstract
The utility model relates to a non-contact type three-dimensional fluorescent magnetic powder flaw detector, which belongs to a detection technology in physics, and overcomes the defect of the existing two-dimensional flaw detector that the clamping direction needs to be changed and flaw detection needs to be carried out repeatedly for parts with complex shapes and structures.The non-contact type three-dimensional fluorescent magnetic powder flaw detector comprises a rack, a cover, a magnetic powder suspension spraying mechanism and an ultraviolet light source. In the improvement, a roller, a conveyor belt and a conveyor belt driving mechanism are arranged on the rack to form a conveying device for a part to be tested; and two vertical magnetic application coils are arranged on the rack and are sleeved on the front part and the rear part of the conveyor belt, four magnetic application coils are arranged on the periphery of the conveying belt between the two vertical magnetic application coils, two magnetic application coils are arranged in a group, and thus a magnetizer is formed. The utility model has the beneficial effects that the process of clamping the part to be tested on the flaw detector is eliminated, the operating process is simplified, the magnetizer produces a three-dimensional orthogonal magnetic field for full-range magnetization of the part, cracks on each interface and in each direction can be detected, no repeated detection is needed, and the flaw detection efficiency is greatly increased.
Description
Technical field
The invention belongs to the detection technique in the physics, be specifically related to fluorescent magnetic particle inspection machine.
Background technology
At present,, mostly be two-dimensional structure from the mode of magnetization with MPI fluorescent magnetic particles method defectoscope to magnetizable mechanical component flaw detection, promptly by the part holding electrode to the part circumferential magnetization of directly switching on, with hot-wire coil seized part is imposed longitudinal magnetization.This magnetization configuration can make than the crackle omission perpendicular to circumference trend on the plane of holding electrode line on the complex parts.For avoiding the appearance of this situation, than complicated parts, the conversion seized part to carry out secondary or detection more than twice to shape, structure in interelectrode clamping direction, be used to avoid rejected part, hide some dangers for to plant equipment.This flaw detection repeatedly that same part is carried out has strengthened the flaw detection workload, has reduced work efficiency.
Summary of the invention
The purpose of this invention is to provide a kind of non-contact 3-D fluorescent magnetic particle inspection machine, be used for magnetisable part flaw detection, overcome the deficiency that the existing two-dimensional defectoscope needs conversion clamping direction to repeat to detect a flaw to shape, baroque part.
Defectoscope of the present invention comprises frame, outer cover, magnetic suspending liquid spraying mechanism, ultraviolet source.The improvement of being done is: belt idler is installed on frame, conveying belt is installed on carrying roller, the conveying belt drive motor is installed on frame, settle belt or gear drive between drive motor and belt idler, form seized part machine upper conveyor; Vertically execute magnetic coil for two that before and after installing on the frame, are enclosed within on the conveying belt, installing two around vertically executing conveying belt between the magnetic coil at two is that one group four execute magnetic coil, two coils of every group are coaxial and be located at the not homonymy of conveying belt, the axis of two groups of coils is vertical mutually, plane, four coil places is vertical with conveying belt, forms magnetizing apparatus.More than be basic scheme of the present invention.
Occur the demagnetizing field effect for eliminating in the simple coil magnetizing district owing to magnetize the ratio relation of part three-dimensional dimension, of the present invention further improving is that the lines of magnetic induction boundling that soft magnetic material is housed in the coil around the conveying belt focuses on excellent.
The invention has the beneficial effects as follows: cancelled the clamping process of part to be checked, only needed part is placed on simply and can be placed on the conveying belt among the magnetic field, simplified operating process at defectoscope.Be enclosed within one group of coil on the conveying belt and be arranged on the magnetizing apparatus formation three-dimensional orthogonal magnetic field that conveying belt two groups of coils on every side constitute, make the comprehensive magnetization of one-pass tested complex parts, can detect the crackle of each interface, various directions, existing relatively this type of defectoscope, there is not duplicate detection, increases substantially the flaw detection work efficiency.
