Description
Technical field
The present invention relates to a kind of magnafluxs, more particularly, to a kind of universal contact of non-destructive testing magnaflux.
Background technique
Magnetic powder inspection is one of the main method of Surface testing in conventional nondestructive inspection, predominantly detects ferrimagnet table
Face and near surface flaw, steel construction piece, all kinds of metal parts of special equipment and power plant non-destructive testing in all play it is important
Effect.When detecting various complicated metal parts, part detects position and there is limitation, and yoke method magnetic powder inspection is in detection process
In, in addition to the more smooth workpiece in the surfaces such as bulk container and pipeline, there is a situation where that contact is limited or contacts undesirable.Using magnetic yoke
During contact method magnetic powder inspection, contact and component contact directly affect detection sensitivity, therefore in the detection process, detection spirit
The problem of sensitivity Shortcomings, need to be verified by Calibration Piece for Sensitivity, however existing Calibration Piece for Sensitivity contact effect is still not
It is ideal.
Summary of the invention
Simple, design that it is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of structures
The exquisite universal contact of non-destructive testing magnaflux with stronger practicability and operability, to improve the reality of detection
Sensitivity and detection effect.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of universal contact of non-destructive testing magnaflux, including sequentially connected the upper, middle and lower, it is described
The upper and lower are the magnetic part of sheet stepped construction, and middle layer is entity structure, and the upper and lower include living
Dynamic part is fixedly connected with coupling part, described coupling part one end with middle layer, the laminated structure of the coupling part other end and
The laminated structure intersecting of movable part, and be rotatablely connected by shaft, in use, the movable part top on upper layer and magnetic powder
The movable part of the connection of defectoscope main body, lower layer is used for and face contact to be detected.
The movable part end of the lower layer is machined with chamfering.
The shaft is bolt, and one end of bolt is connected with goat's horn nut.
The connection integrated with middle layer of described coupling part one end.
The shaft of the upper and lower is mutually perpendicular to.
The middle layer is ferritic stainless steel.
Compared with prior art, the invention has the following advantages that
(1) the upper and lower in three-decker can be rotated, and expand the applicable scene of yoke method magnetic powder inspection.
(2) the movable part end of lower layer is machined with chamfering, i.e. chamfered edge is handled, and convenient for the detection of corner connection component, improves inspection
The case where during survey with detection faces poor contact, improves the sensitivity and applicable scene of Magnetic testing, makes test result more
It is accurate and reliable to add.
(3) shaft is bolt, and one end of bolt is connected with goat's horn nut, and goat's horn nut is adjusted by rotation elastic, adaptation difference
Sensitivity.
(4) structure is simple, deft design, low cost.
(5) shaft of the upper and lower is mutually perpendicular to, and forms universal adjustment.

Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention
Premised on implemented, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to
Following embodiments.
Embodiment
As shown in figs. 2 to 4, the universal contact of a kind of non-destructive testing magnaflux, including sequentially connected upper layer 1, in
Layer 2 and lower layer 3, upper layer 1 and lower layer 3 are the magnetic part of sheet stepped construction, and middle layer 2 is entity structure, upper layer 1 and lower layer
3 include movable part 4 and coupling part 5, and 5 one end of coupling part is fixedly connected with middle layer 2, the piece of 5 other end of coupling part
The laminated structure intersecting of shape structure and movable part 4, and being rotatablely connected by shaft 6, shaft 6 are bolt, the one of bolt
End is connected with goat's horn nut, can carry out elastic adjusting.The shaft 6 of upper layer 1 and lower layer 3 is mutually perpendicular to.The flat member of lower layer 3 uses
Screw is fixed.
Lower part magnetic yoke contact bottom end uses front and back chamfered edge design, that is, is machined with chamfering, guarantees detection corner structure component and narrow
Contact well protrudes into and contacts when small space.
The connection integrated with middle layer 2 of 5 one end of coupling part.
Middle layer 2 is ferritic stainless steel.
As shown in Figure 1, in use, testing in the case where guaranteeing Plant in good condition its lifting force, to determine its symbol
Standardization requirement, and wettability verification is carried out before Magnetic testing, appropriate tune is carried out to the goat's horn bolt of top and the bottom later
Section, keeping its elastic is suitable for while substantially adjusting contact in advance, makes bottom surface and the detection faces keeping parallelism of contact lower layer 3, when detection
Magnaflux is held, light rancour contact adjusts integral contact freely in both direction, makes entire contact bottom surface fitting detection
Face.Contact is well contacted with detection faces, is the important leverage of Magnetic testing sensitivity.
