Description
Technical field
The utility model belongs to microwave device and makes the field, specially refers to a kind of millimere-wave band coupled-cavity TWT slow wave system soldering moulds of industrial equipment.
Background technology
Travelling-wave tubes is in modern satellite communication, satellite navigation, bringing into play huge effect especially in military electronics such as electronic jamming device, prior-warning plane, fire control radar, accurate guidance.Coupled-cavity TWT is the all-metal construction device, and the slow wave system parts are vitals of travelling-wave tubes, and number of spare parts is many, weld seam is many, parts are long.When soldering, should guarantee good concentricity and fitted position, guarantee vacuum-tightness again.Therefore, high especially to the brazing quality requirement, and the moulds of industrial equipment of soldering are preconditions that guarantees to obtain high-quality soldering.For millimeter wave traveling wave tube, coupler size and drift tube diameter are read all very little, be difficult to guarantee good concentricity when soldering, and this are the whether qualified keys of decision millimeter wave traveling wave tube parameter.Present soldering moulds of industrial equipment adopt briquetting mostly or with support and screw fixation method, can't satisfy the requirement of the high concentricity of millimeter wave traveling wave tube slow-wave system, therefore must adopt more accurate soldering moulds of industrial equipment.
Summary of the invention
Technical problem to be solved in the utility model is, at the deficiencies in the prior art, a kind of soldering moulds of industrial equipment of millimeter wave coupled-cavity TWT slow wave system are provided, do not change, can not be out of shape with the relative position that reaches each part in the slow wave system parts that both can guarantee to assemble, and can guarantee the concentricity that slow wave system is good.The purpose of this utility model is to provide a kind of millimeter wave traveling wave tube slow-wave system soldering moulds of industrial equipment.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of millimeter wave traveling wave tube slow-wave system soldering moulds of industrial equipment comprise the base, the base plate that are positioned at bottom, erect the soldering support that columns assemblies, pressing plate, briquetting on it are formed; It is characterized in that, include two-layer buffer stopper up and down between described base and the pressing plate, keep the space of placing slow wave system to be brazed up and down between the buffer stopper in advance.By constraint buffer stopper of three root posts between base and the briquetting and slow wave system parts, thereby better guarantee the concentricity that slow wave system is good; Described pressing plate center is provided with a pair of mesopore, and briquetting applies certain pressure from pressing plate mesopore is passed equably to slow wave system, thereby better guarantees the sealing of soldering slow wave system.
In the millimeter wave traveling wave tube slow-wave system soldering moulds of industrial equipment, described column divides three kinds, is respectively vertical columns, location column, assembling column, on the column of location spacer is housed.The material of column and spacer is the molybdenum material.
Described buffer stopper is identical with the outside dimension of slow wave system parts, and there is passage at the buffer stopper center, and the side has locating slot.
Have three locating holes on the described base, and between vertical columns and the location column for being slidingly matched, be that win cooperates with the assembling column.
The soldering frock of millimeter wave coupled-cavity TWT slow wave system, owing to adopted said structure, compared with prior art: both guaranteed the rigging position between the slow wave part, and in the process of soldering, the rising of Yin Wendu, slow wave and base all can expand, wherein at horizontal direction, the swell increment of base and slow wave is suitable, and the Mo column does not expand substantially, thereby the slow wave part is not changed in the lateral attitude, well guaranteed the concentricity of slow wave system; At longitudinal direction, the expansion of slow wave system is upwards backed down briquetting, but the briquetting that slides exert pressure can for all the time slow wave system uniformly, makes that the weldquality of slow wave system is more reliable after the soldering.So the frock that adopts this form can improve the brazing quality of millimeter wave slow wave system greatly.This method also can be applied in the soldering of other parts simultaneously.

The specific embodiment
Referring to figs. 1 through Fig. 8, the soldering moulds of industrial equipment of representing a kind of millimeter wave coupled-cavity TWT slow wave system, comprise by base 1, base plate 2, erect the location columns assemblies 3 on it, the vertical columns of forming by molybdenum column 9 and spacer 10 4, assembling column 5, pressing plate 7, the soldering support that briquetting 8 is formed, at base 1, place two-layer buffer stopper 6 up and down successively between pressing plate 7 and three columns, keep the space of slow wave system to be brazed up and down between the two-layer buffer stopper in advance, when carrying out soldering with buffer stopper 6 and slow wave system to be brazed, align with the spacer 10 of location on the column by buffer stopper locating slot 15, press briquetting 8, ensure to slow wave system and evenly apply certain pressure.
Described base 1 is provided with center, three 12, three holes of equally distributed locating hole and forms that round size is put into the back with three root posts and the slow wave part is tangent is as the criterion, and as shown in Figure 2, has the screwed hole 13 that is connected with locating hole in the base side; Have passage 14 and locating slot 15 on the bolster 6; Location column 3 is made up of molybdenum column 9 and spacer 10, and by screw hole 11 both is fixed; The local size that the bottom of assembling column 5 cooperates with base 1 is done little, more helps the parts assembling; Have the screw hole 17 that three locating holes 16, through hole 18 and side communicate with locating hole on the pressing plate 7; A step is done to abdicate spacer 10 position occupied in the side of briquetting 8, more helps the slip of briquetting 8 between column.
During assembling, at first base 1 and base plate 2 are fixed by screw rod 21; Vertical columns 4 and location column 3 are put into the locating hole 12 of base 1, and the position of adjusting spacer 10 fixes vertical columns 4 and locatees column 3 with screw rod 19; Put into bolster 6, slow wave part 22, bolster 6 successively, guarantee that locating slot and spacer are to it, as shown in Figure 2; Put into assembling column 5, and fix with screw rod 19; Cover pressing plate 7, fix with screw rod 20 again; From through hole 18, insert briquetting 8, finish whole assembling process.
In the brazing process of slow wave system, the rising of Yin Wendu, slow wave system parts 22 and base 1 can thermal expansions.Wherein at horizontal direction, the swell increment of base and slow wave is suitable, and the Mo column does not expand substantially, thereby the slow wave system parts are not changed in the lateral attitude, has well guaranteed the concentricity of slow wave system; At longitudinal direction, the expansion of slow wave system is upwards backed down briquetting, but the briquetting that slides exerts pressure can for all the time slow wave system uniformly, makes that the weldquality of slow wave system is more reliable.So the frock that adopts this form can improve the brazing quality of millimeter wave slow wave system greatly.
