Abstract
The utility model relates to a split movable coil winding wall tube structure with a lower reinforced ring, which comprises a straight tube-shaped winding wall tube fixed on the lower end of a movable coil framework. The utility model is characterized in that the straight tube-shaped winding wall tube is formed by separate type butt match of a left half split wall tube gap and a right half split wall tube gap, the lower end of the winding wall tube is provided with the lower reinforced ring which are extended toward the inner side and the outer side, and the circumferential direction on the lower reinforced ring is provided with a desquamation preventing surface corresponding to an inner-outer double-layer drive coil winding. The winding wall tube is designed into split structure with the lower reinforced ring by the scheme to prevent coil winding dispersing and desquamating. Because the lower end of the novel structure drive coil winding adds a conductor wire retainer ring, namely, the lower reinforced ring, the technical difficult of easy separation and desquamation under the high frequency and high acceleration is completely overcome.
Description
Technical field
The utility model relates to the vibration test electric vibration table, is specifically related to the split type moving-coil coiling wall barrel structure of ring stiffener under a kind of air-cooled electric vibration table band.
Background technology
In the electric vibration table structure, moving-coil as the oscillating component floating support in the magnetic field that field copper provides.Say that in a sense moving-coil is the core of whole electric vibration table, its structure and performance directly influence the overall performance and the effect of electric vibration table.
Moving-coil mainly is made up of work top, skeleton and drive coil winding three parts.Because the electric current that drive coil feeds at work is very big, can cause the drive coil heating, therefore need implement to force cooling to it.In the past in the known technology, the type of cooling of drive coil in the moving-coil is had two kinds, a kind of is air-cooled, and another kind is a water-cooled.Generally speaking, air cooling way is simple in structure, and cost is low, is applicable to the middle-size and small-size electric vibration table of 6 tons of following thrusts, and the water-cooling pattern complex structure, and the cost height is applicable to the Large Electric shaking table of thrust more than 6 tons.
All be Double Layer Winding usually for air-cooled electric jigging platform moving coil, and coiling wall tube is best version in the centre of two-layer winding, sees shown in Figure 1.Because, the first, coiling wall tube is in the centre, and the leakage field induction reactance minimum of moving-coil has reduced the AC impedance of moving-coil, the output power of having saved power amplifier; The second, (promptly inside and outside armour plate structure) influences air-cooled effect to coiling wall tube on inside and outside both sides unlike coiling wall tube in the centre.So middle coiling wall barrel structure is widely used on the moving-coil structure of air-cooled electric vibration table.
But there is a serious defective for a long time in the moving-coil of this structure, is exactly easily diffusing the taking off in lower end of coil winding.Because the coiling wall tube of this structure is exactly a separate type straight cylinder (i.e. " C " type open loop type straight cylinder) that is rolled into aluminium sheet, thereby winding only depends on epoxy glue and coiling wall tube to bond together, its upper end is near moving coil framework, and the lower end does not keep off head, the direction of vibration of moving-coil is to move up and down when working because of shaking table, so moving-coil lower end winding looses easily and takes off after standing high frequency, high acceleration vibration.The quality accident that moving coil winding is loose and taken off also appears in the shaking table product of some international famous brand company even be under warranty, thereby has had a strong impact on the reliability and the life-span of moving-coil.
Summary of the invention
The utility model proposes a kind ofly with the following split type moving-coil coiling wall barrel structure of ring stiffener, its purpose is to prevent that the drive coil winding from taking place to loose in the work lower end takes off.
For achieving the above object, the technical solution adopted in the utility model is: a kind of split type moving-coil coiling wall barrel structure with following ring stiffener, comprise the straight barrel type coiling wall tube that is fixed on the moving coil framework lower end, this straight barrel type coiling wall tube is formed assembly by the split type wall tube of left and right sides two halves gap separate type, coiling wall tube lower end is provided with a following ring stiffener that extends to inside and outside both sides, and corresponding inside and outside double-deck drive coil winding lower end is being circumferentially with the anticreep face on the following ring stiffener.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described " the gap separate type is to piecing together " is meant that two halves split type wall tube in the left and right sides can not constitute closed loop to assembly the time, to avoid producing circulation because of induction at work.Therefore, straight cylinder type coiling wall tube in the past also adopts the open loop separate type.
In the such scheme, consider from processing technology that 2, following ring stiffener and split type wall tube can be structure as a whole, perhaps, following ring stiffener is fixedlyed connected with split type wall tube and is integral.Describedly fixedly connectedly comprise that welding, screwing adds splicing, rivet and connects and add splicing etc.
3, in the such scheme,, make bonding more solid and reliablely, all offer epoxide-resin glue exhaust seep through hole on described each split type wall tube in order to eliminate coiling wall tube and the bonding gas hole defect of inside and outside double-deck drive coil winding.Described exhaust seep through hole is along circumferentially and vertically evenly being provided with.
4, the characteristics of this programme are: coiling wall tube separates, split, and has ring stiffener down, and coiling wall tube in the past then is to separate, and the lower end does not keep off head (following ring stiffener).
Principle of work of the present utility model is: at above-mentioned hard nut to crack, this programme has carried out structure innovation, and coiling wall tube is designed to have the structure of ring stiffener down, takes off to stop the diffusing of coil winding.Because the lower end of the drive coil winding of new construction has increased a lead back-up ring---promptly descend ring stiffener, so overcome the technical barrier that lead easily looses and takes off fully under the high frequency high acceleration.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
1, this programme is skillfully constructed, and is simple in structure, good anti-drop effect.
2, this programme coiling wall tube adopts split-type design, is convenient to the processing and the manufacturing of moving-coil.
3, this programme helps improving the life-span and the reliability of moving-coil.
