Description
Technical field
The utility model relates to a kind of microwave electronic device anchor clamps, in particular, relates to a kind of anchor clamps of novel helix TWT collector chamber end cap.
Background technology
In electron tube, the common structural material mainly comprises copper, nickel and alloy material thereof etc.These metal materials are the main materials that constitute electron tube, and the quality of these materials and the correctness that is used directly affect the mechanical strength and the vacuum-tightness of electron tube.
To electron tube; What the air-tightness of weld seam required obviously will to compare mechanical strength requires even more importantly, and for the collector chamber end-cap assembly that we use now, what its main material adopted is copper-nickel alloy and ferrous metal thereof; It is very extensive that these two kinds of metal materials are used in electron tube; And soldering processes also are more common, but there is bigger hidden danger in the quality of soldering processes always, therefore; For improving the brazing quality of parts, will carry out darker research and improvement to the structure and the brazing jig of chamber end cap.
In CW TWT; The chamber end cap of collector mainly comprises the disc of pure iron material, the chamber end cap sleeve of copper-nickel alloy material and electron gun end cap sleeve, and used scolder is an oxygen-free copper; But generally; The temperature that oxygen-free copper melts in the hydrogen stove is 1083 ℃, and according to different soldering requirements, we can do the adjustment of a little necessity to this temperature.For example the application discusses the chamber end cap parts of research, if then can't reach satisfied brazing quality according to normal soldering processes, thus will be to the material of parts, the research of making amendment of brazing temperature and brazing jig.
Copper-nickel alloy has higher mechanical properties, has good corrosion resistance and hot-working character simultaneously, and conductance is low, and is nonmagnetic.Pure iron is the more active metal of chemical property, is prone to oxidized formation stable oxide---FeO and Fe at normal temperatures
2O
3So we usually can carry out electroless nickel layer or copper layer on the surface of ferrous metal, to prevent the iron oxidation.Coating can also let the scolder can be better wetting and trickling.In original technology, the effect of each soldering is not fine, though the oxygen-free copper scolder has trickling preferably not have real " thoroughly " trickling on the surface of metal material, does not promptly trickle fully and comes to the reverse side of metal parts.
Fig. 1 is the structural representation of traditional travelling-wave tubes collector chamber end cap anchor clamps; As shown in Figure 1: traditional travelling-wave tubes collector chamber end cap anchor clamps all comprise disc 1, chamber end cap sleeve 2 and electron gun end cap sleeve 3; The inwall of anchor clamps itself is thicker; And have only a ventilation mouth, be easy to cause inner parts, cause scolder can't infiltrate into reverse side because of being heated inhomogeneous or being heated inadequately.
Fig. 2 is the structural representation of traditional improved travelling-wave tubes collector chamber end cap anchor clamps; As shown in Figure 2: as on the basis of travelling-wave tubes collector chamber end cap anchor clamps shown in Figure 1, increased traditional briquetting 7, but traditional briquetting 7 still to be to have only a ventilation mouth; Remainder all seals; Be difficult to guarantee that anchor clamps are heated evenly fully, and processing technology is complicated, cost of manufacture is high.
Summary of the invention
Be to solve the deficiency of prior art, the purpose of the utility model is to provide a kind of and makes that the component exposed area is big, the brazing jig of helix TWT collector chamber end cap fully is heated evenly.
For achieving the above object, the utility model is to realize through following technical scheme:
The brazing jig of a kind of helix TWT collector chamber end cap; Comprise disc, chamber end cap sleeve and electron gun end cap sleeve; Also comprise briquetting and pressure ring, said briquetting is arranged at said electron gun end cap sleeve top, and said pressure ring in the form of a ring; Be arranged at the top of described disc, and be socketed on the periphery of described electron gun end cap sleeve.
In order to make the more tight and consumption of reducing friction of contact between pressure ring and the disc, between described pressure ring and described disc, also be provided with the ceramic whiteware gasket ring.
Be pressed on the described electron gun end cap sleeve for briquetting is overlapped more stably, the bottom of described briquetting is provided with a groove, and the top of described electron gun end cap sleeve extend in the described groove.
Further, the material of described briquetting and pressure ring is for can cut down material chromium plating.
In addition, the material of described disc is the copper facing of pure iron material surface, and the thickness of described disc (1) copper coating layer is the 12-15 micron.
The beneficial effect of the utility model is: the described anchor clamps of the utility model are exposed in the hydrogen stove parts itself, make it to be heated evenly fully, to reach satisfied brazing quality, bury air-tightness hidden danger when reducing next step parts soldering; In addition, the described anchor clamps processing technology of the utility model is simple, and cost of manufacture is low, and very strong practicality is arranged.
