Description
Technical field
The utility model relates to a kind of hot compression anchor clamps of helical line for travelling wave tube slow wave system, belongs to microwave electronic device manufacturing process field.
Background technology
In the helix line traveling wave tube slow-wave system manufacture process, all strengthen the contact strength (tightness degree of clamping) between supporting rod, helix and the shell in the method for pursuing through pyrocondensation, come further to increase its heat-sinking capability.Therefore, be necessary very much the pyrocondensation anchor clamps of slow wave system are carried out rational research and design.
The method of gripping between the helix of travelling wave tube, supporting rod and the shell three has much, and method commonly used at present has two kinds:
A kind of is after the cold method of suppressing is assembled the three; Outside shell, put three lobe stainless steel chucks of tapering and step; Again the chuck skin put with the less even molybdenum collar of the coefficient of expansion of chuck coupling with banding, still, have the stainless steel chuck of tapering and step to have only and partly received the pyrocondensation extruding with the molybdenum loop contacts; And the centre has a small half of zone not have the molybdenum hoop to live, so this part regional pyrocondensation effect is relatively poor relatively.
Another kind is that three lobe stainless steel chucks do not have tapering and step, outside it, directly puts the molybdenum ring.Afterwards assembly is put into the hydrogen stove and be heated to uniform temperature; The coefficient of expansion of the molybdenum collar is less because the stainless coefficient of expansion is big makes it produce an inside pressure to shell; Reach the purpose of hot compression; The method can't accurately be controlled the gap between the stainless steel chuck and the molybdenum collar, causes between theoretical compressed value and the reality inconsistently, and it is more undesirable to compress effect.
The collar of these two kinds of methods all is a Mo, costs an arm and a leg and carries out becoming fragile easily after the pyrocondensation several times and cracking or distortion under the extruding force effect, causes the bad control of consistency of hot compression technology.
The utility model content
The technical problem that the utility model will solve is; To the pyrocondensation technology anchor clamps in past, in use,, high temperature deformation fails to realize clamping owing to being prone to cause the slow wave system structure after the pyrocondensation; Fastness is poor, weak heat-dissipating, thermal stability are bad; In order to overcome these shortcomings, further increase the heat-sinking capability of slow wave line, just need further to improve the anchor clamps of this hot compression technology.The purpose of the utility model provides a kind of hot compression anchor clamps of helical line for travelling wave tube slow wave system.For realizing this purpose, the technical scheme that the utility model adopted is following:
The utility model is achieved in that a kind of hot compression anchor clamps of helical line for travelling wave tube slow wave system, comprises pedestal, sleeve, stainless steel round bar, briquetting, screw rod, three lobe chucks, slow wave system; It is characterized in that said pedestal is that interior sky and top are provided with the screw that is used to assemble said screw rod, said sleeve is that integral cutting forms; Be located at said pedestal inner bottom part, said briquetting bottom is tapering, is located at said base interior; With said base internal wall close-fitting, said stainless steel round bar is located on the ladder of said upper cartridge position, with the tapering close-fitting of ladder and said briquetting; Said screw rod is located on the screw of said pedestal upper part; Said three lobe chuck integral body are located at said sleeve inner, and said slow wave system is located at three lobe chuck centres, and described slow wave system, three lobe chucks, sleeve be close-fitting successively.
Further said upper cartridge position is notch cuttype, is provided with a breach in the middle of the upper part, under relaxed state, is convenient to assembling and dismantles three lobe chucks.
The material of further said sleeve is 4Cr13.
Further the material of said three lobe chucks is an electrical pure iron.
The utility model compared with prior art, beneficial effect is: the utility model changes the material of the sleeve of traditional pyrocondensation anchor clamps the material of 4Cr13 into, like this; When high temperature expanded, because the difference of the coefficient of expansion, three lobe chucks were bound round together by sleeve tightly; Because the power of screw rod exists all the time; And sleeve is all-in-one-piece, thus in the heating and cooling process three lobe chucks all integral body be under the uniform squeezing action, when the cooling after; As long as screw rod is unclamped, can easily take out chuck and slow-wave component.In the pyrocondensation process, because the effect of screw pressure is can not have the gap between sleeve and three lobe chucks, this has also been avoided the unmanageable problem in gap of traditional pyrocondensation anchor clamps fully.
The hot compression anchor clamps of a kind of helical line for travelling wave tube slow wave system that the utility model execution mode provides; Adopt integral type outer sleeve jaggy; Make no matter be high temperature or cooling; Slow wave system all can be whole by tightly compression; And owing to be to have outer screw to exert pressure in indentation, there all the time, thus avoided between traditional sleeve and three lobe metal collets because gapped and the pyrocondensation weak effect that causes and pyrocondensation amount be difficult to problem such as control, thereby the purpose that whole structure is good and precision is high of realization slow wave system deflation.
Evenly exert pressure and all-in-one-piece sleeve framework can be controlled slow wave system whole effect that receives uniform power in the pyrocondensation process well through screw rod; And owing to the disappearance in the gap that was difficult to calculate makes the pyrocondensation amount be able to accurate control in the past, thereby make the pyrocondensation uniformity of slow wave structure and reliability be able to obvious improvement.
