Magnetic field will occur distortion, form part magnetic flux leakage workpiece surface and generate stray field, so as to attract magnetic powder (more by
Magnetic flaw detection ink provide) formed fault location magnetism powder accumulation --- magnetic trace under appropriate illumination condition, shows defective locations and shape
Shape is observed and is explained to the accumulation of these magnetic powders, is achieved that magnetic powder inspection.Existing magnetic powder inspection, magnetic flaw detection ink are general
It is sprayed by the way of spray on workpiece, but for some workpiece in irregular shape, magnetic flaw detection ink clamping is inconvenient, spray
Uneven to workpiece surface, causing flaw detection, there are blind areas.CN106404894 discloses a kind of facility of magnetic powder inspection, and magnetic powder is visited
Hinder machine, including rack, controller and magnetic flaw detection ink storage box, controller connection magnetization probe are provided in the rack
And degaussion coil, the surrounding of the magnetic flaw detection ink storage box are provided with guide rod, lifting support is through the guide rod and passes through liter
It drops driving device to be mounted in the magnetic flaw detection ink storage box, web plate is provided on the lifting support.But flaw detection it is all-round to
Magnetic field generation device is even more important, it is necessary to have this magnetic field and ensure that comparable magnetic field intensity just can visited important part
It can be seen the defects of all directions when hindering, shown because only that could understand in the crackle vertical with magnetic direction.
Utility model content：
It is all-round to magnetic field generation device that the purpose of this utility model is to provide a kind of flaw detection of magnaflux, for any shape
The workpiece of shape can cause magnetic flaw detection ink uniform fold that can be exposed in workpiece surface and the defects of making all directions on workpiece,
Improve the comprehensive and accurate property of flaw detection.
The purpose of this utility model is realized by following technical solution：Flaw detection with all-round to magnetic field generation device, including
Work durm, first coil, the second coil and tertiary coil, the second coil and tertiary coil are orthogonal, and the second coil is nested in
In three-winding, the inner space of the second coil and tertiary coil accommodates work durm and enters；Doorframe is prepared into the second internal coil
Shape can simultaneously be turned to is embedded in the inner wall of work durm with horizontal direction with the conplane position of tertiary coil, first coil.Doorframe
The position of central shaft up and down of second coil of shape is equipped with stent and axis pin, and the second coil can be rotated around axis pin.
The first coil is two groups of parallel coils, is embedded in the upper-lower position of work durm；Work durm equipped with track
Upper slip.
The all-round course of work to magnetic field generation device of detecting a flaw is as follows：First coil, the second coil and tertiary coil connect
The power supply of high current, work durm are magnetic flaw detection ink spraying box or magnetic flaw detection ink storage box, and rotating the second coil of doorframe shape makes the second coil
When parallel with tertiary coil, work durm along track is pushed into the inner space of the second coil and tertiary coil, rotates doorframe shape
Second coil makes the second coil be powered with tertiary coil and adds magnetic field, and workpiece to be detected a flaw is in work durm, magnetic flaw detection ink spray or magnetic flaw detection ink
It is imaged and is observed in magnetic field after submergence.Second coil with tertiary coil there are gap can be installed and hang workpiece again
Carrier chain (carrier chain is compact, and the structure detachably to install) does not influence the disengaging of workpiece.
Advantageous effect：The full Circumferential field of flaw detection that the utility model generates so that workpiece is all in three-dimensional full Circumferential field
It is middle receive observation and flaw detection so that magnetic flaw detection ink uniform fold receives flaw detection in workpiece surface, improve flaw detection accuracy and comprehensively
Property.
Description of the drawings：
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the cross-sectional view of Fig. 1.
In figure：Work durm 1, first coil 2, the second coil 4 and tertiary coil 3, the second coil central axe position are equipped with stent 7
Hole 7 is collected with axis pin 8, track 6, magnetic flaw detection ink spray.
Specific embodiment：
In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate.It should be understood that following specific embodiments
It is merely to illustrate the utility model rather than limitation the scope of the utility model.
Embodiment 1：
As shown in Figure 1：The second coil and tertiary coil are orthogonal (at work) when electric can provide magnetic field work, and second
Coil is nested in tertiary coil, and the second coil, the area of tertiary coil are close and the inside of the second coil and tertiary coil is empty
Between accommodate work durm enter；The second coil in being nested in is prepared into doorframe shape and can turn to conplane with tertiary coil
During position, first coil is with the inner wall of horizontal direction insertion work durm.The position of central shaft up and down of second coil of doorframe shape is equipped with
Stent and axis pin, the second coil can be rotated around axis pin.First, second coil and tertiary coil are able to that high current is allowed to lead to
The coil crossed；The all-round course of work to magnetic field generation device of magnetic powder inspection flaw detection of the present embodiment is as follows：First coil, second
Coil and tertiary coil connect the power supply of high current, and work durm is magnetic flaw detection ink spraying box or magnetic flaw detection ink storage box, rotates doorframe shape
When second coil makes the second coil parallel with tertiary coil, work durm is pushed into the inside of the second coil and tertiary coil along track
Space, rotating the second coil of doorframe shape makes the second coil and tertiary coil energization plus magnetic field, and workpiece to be detected a flaw is in work durm, magnetic
It is imaged and is observed in magnetic field after suspension spray or magnetic flaw detection ink submergence.Second coil and tertiary coil can be with there are gap
Or else the disengaging of workpiece is influenced.For stent 7 with axis pin 8 using 304 stainless steels, this is non-magnetic metal.
The course of work：Workpiece to be detected a flaw is sprayed into magnetcisuspension in the utility model device and under the premise of existing for magnetic field
Liquid is detected a flaw, and workpiece passes through anti-magnetized coil demagnetization again after flaw detection.
