The defect axially vertical with coil.During various aircraft repair, screw, bolt and cotter diameter are usually no more than 20mm etc. and need magnetic powder
The axle class finding quantity of detection reaches thousands of, and workload is big, the cycle is long.By national military standard 2028A " Magnetic testing " requirement, for
During screw isometry class finding longitudinal magnetization, for reducing the impact on workpiece magnetizing of the coil method demagnetizing field, meet magnetic powder inspection spirit
Sensitivity, need to be placed on coil inwall on machine during magnetization after the most engaging one another for these parts again, and axial along coil
Arrangement.
But on existing magnaflux machine, coil is all the little width of major diameter, i.e. width is less with diameter ratio, such as certain
Type magnaflux coil diameter 600mm, width 120mm, coil 6 circle, coil parameter K is 9.8, and coil inwall is axially gone up at most
The total length axial workpiece less than coil 120mm width can only be placed.As a example by certain pin batch magnetic powder inspection, this pin is long
20mm, once magnetize at most can only 6, work efficiency is the lowest, and owing to coil parameter K is less, also needs to bigger during magnetization
The electric current of value.
Summary of the invention
In order to solve above-mentioned technical problem, this utility model provides a kind of axle class finding longitudinal magnetizing device.
This utility model solves its technical problem and realizes by the following technical solutions:
A kind of axle class finding longitudinal magnetizing device, including wooden rack, fixing screw, insulation clamping support stick, felt pad
Plate, coil, coil insulation fixed strip, housing screw, the middle part of described coil is the spiral type cylindrical coil that copper bar is uniformly coiled into,
Two of coil twists into the right the platy structure being parallel to each other and uses electric conductivity good with formation energising chuck, the position of energising chuck
Good copper material is made, and described insulation clamping support stick is arranged between energising chuck by fixing screw, and such structure designs
Can ensure that effective clamping of the coil two battery lead plates with magnaflux, described wooden rack is provided with the spiral shell constituted with coil
The arc groove that the lower outside profile of rotation shape cylindrical coil matches, described insulating pad is positioned at the spiral type that coil is constituted
On the lower inside wall of cylindrical coil, described insulating pad is connected by housing screw and wooden rack, and wooden rack plays supports, surely
The effect of solidus circle, described coil insulation fixed strip is along the axis direction being parallel to the spiral type cylindrical coil that coil is constituted
It is fixed on the upper outside wall of the spiral type cylindrical coil that coil is constituted, thus realizes the sizing to coil, prevent logical
After electricity, coil loosens.
The copper bar of described coil is monolayer.
The number of turn of described coil is, loop length 360mm, diameter 95mm, and coil parameter constant K is 16.
For the longitudinal magnetization of axle class finding, multiple spare parts can be joined to one another vertically, but quantity needs really
Protecting less than coil effective magnetizing length, be energized back magnetization.
Described insulating pad is arc platy structure.
The beneficial effects of the utility model are: this utility model has reasonable in design, the advantage such as easy to use, both may be used
Realizing the disposable fast-magnetic of multiple axle class finding, improve efficiency, also a saving energy resource consumption simultaneously, practicality is very
By force.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is front view of the present utility model；
Fig. 2 is top view of the present utility model；
Fig. 3 is the plan structure schematic diagram after removal coil insulation fixed strip of the present utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and beneficial effect clearer, below in conjunction with accompanying drawing, to this
The preferred embodiment of utility model is described in detail, and is described further this utility model, to facilitate technical staff to manage
Solve.
As shown in Figure 1 to Figure 3, a kind of axle class finding longitudinal magnetizing device, including wooden rack 1, fixing screw 2, insulation
Clamp standoff rod 3, insulating pad 4, coil 5, coil insulation fixed strip 6, housing screw 7, the middle part of described coil 5 is that copper bar is equal
The even spiral type cylindrical coil being coiled into, two of coil 5 twists into the right the platy structure that is parallel to each other to form energising chuck, logical
The copper material that the position of electricity chuck uses electric conductivity good is made, and described insulation clamping support stick 3 is arranged on logical by fixing screw 2
Between electricity chuck, the design of such structure can ensure that effective clamping of the coil two battery lead plates with magnaflux, described wood
Bracket 1 is provided with the arc groove that the lower outside profile of the spiral type cylindrical coil constituted with coil 5 matches, described absolutely
Edge backing plate 4 is positioned on the lower inside wall of the spiral type cylindrical coil that coil 5 is constituted, and described insulating pad 4 is by compressing spiral shell
Nail 7 is connected with wooden rack 1, and wooden rack 1 plays support, the effect of firm coil 5, and described coil insulation fixed strip 6 is along parallel
The axis direction of the spiral type cylindrical coil constituted in coil 5 is fixed on the upper of the spiral type cylindrical coil that coil 5 constituted
On lateral wall, portion, thus realize sizing to coil 5, prevent loosening of coil 5 upon power-up.
Described insulating pad 4 is arc platy structure.
The main indirect current of Magnetic testing, for reducing inductance and the impact of coil impedance, it is desirable to coil turn can not be too many,
Wire is generally big wire or copper bar monolayer coiling.The copper bar of described coil 5 is monolayer, and the number of turn of described coil 5 is 6, coil
Length 360mm, diameter 95mm, coil parameter constant K is 16.
During work, this device is sandwiched in magnetic and visits between machine two battery lead plate.For the longitudinal magnetization of axle class finding, can be by multiple
Spare part is joined to one another vertically, but quantity need to guarantee less than coil effective magnetizing length, and be energized back magnetization.
As a example by certain type magnaflux: loop length 120mm that this equipment carries, diameter 600mm, coil parameter constant
K is 9.8.The longitudinal magnetizing device that this utility model designs and produces, coil width is increased to 360mm by 120mm, diameter by
600mm is reduced to 80mm, K value and is then increased to 16.27 by 9.8, is on former machine 1.6 times of coil K value.Practical proof shows, logical
Cross external longitudinal magnetizing device of the present utility model, originally can only once magnetize certain profile shaft class finding of n quantity, nowadays may be used
Once magnetization 3n, work efficiency improves 3 times.Meanwhile, this utility model improves 1.6 times because of k value so that required magnetizing current
Value decreases 37.5%, is also effectively saved electric energy.
Finally illustrating, preferred embodiment above is only in order to illustrate the technical solution of the utility model and unrestricted, to the greatest extent
This utility model is described in detail by pipe by above preferred embodiment, but those skilled in the art should manage
Solve, in the form and details it can be made various change, without departing from this utility model claims institute
The scope limited.
