Abstract
The invention discloses a flexible magnetic yoke device. The flexible magnetic yoke device comprises a plurality of strands of steel wire ropes, a conductive coil, two ferromagnetic shoes and an interval and angle adjustment control device. The multiple strands of steel wire ropes are adopted as a flexible electromagnetic yoke, the interval and the angle between the two magnetic shoes of the flexible magnetic yoke can be freely adjusted, and thus the technological requirements of flaw detection for different magnetic shoe intervals and different coupling angles are met in magnetic powder flaw detection.
Description
Affiliated technical field
The present invention relates to a kind of the cannot-harm-detection device, particularly relate to the flexible magnetism yoke device that a kind of fracture detection by magnetic powder is used.
Background technology
General fracture detection by magnetic powder all adopts silicon steel sheet to make iron core with electromagnetic yoke and repeatedly makes and form, and the method electromagnetic conversion efficiency is high, loss is little, is difficult for adjusting but bring thus with the coupling gap of surface of the work, cannot reach optimum detection effect.
Summary of the invention
The object of the invention is to overcome the deficiency of prior art, design a kind of flexible magnetism yoke device, adopt multistrand rope to make flexible electrical yoke.
The technical solution adopted for the present invention to solve the technical problems is: a kind of flexible magnetism yoke device is provided, it is characterized in that, comprise multistrand rope, conductive coil, two ferromagnetic boots, spacing angle adjustment control device; Conductive coil is fastened outside the middle part of described multistrand rope; Two end faces of multistrand rope are fixed respectively ferromagnetic boots; By the two ends of multistrand rope to middle part bending, between the two ends of the multistrand rope after bending, install and fix a spacing angle adjustment control device, described spacing angle adjustment control device can be controlled the relative angle between spacing and the ferromagnetic boots bottom surface between the ferromagnetic boots in multistrand rope two ends after bending.
The invention has the beneficial effects as follows, a kind of flexible magnetism yoke device, adopt multistrand rope to make flexible electrical yoke, spacing and angle between two magnetic boots of flexible yoke can regulate arbitrarily, meet the defects detecting technology requirement of different magnetic boots spacing in fracture detection by magnetic powder and different coupling angles.
