Abstract
The utility model discloses a braze tool of a composite pipe shell slow-wave part. The braze tool of the composite pipe shell slow-wave part. The braze tool comprises a support base, a support press plate, a support pillar, a locating base, a locating press block, a press ring and a sleeve. The locating base is arranged on the support base. The support press plate is arranged on the support pillar in a sleeved mode through a fastener. The bottom of the slow-wave part is arranged on the locating base. The sleeve is connected to the slow-wave part in a sleeved mode. The press ring is arranged on the sleeve in a sleeved mode. A guide rail hole is formed in the support press plate. The locating press block penetrates through the guide rail hole to be arranged on the top of the slow-wave part. In the process of brazing, due to rising of the temperature, the stainless steel press ring and a sleeve outside the lei slow-wave part will expand due to heat. Due to the expansion coefficient of the lei sleeve is lower than that of the stainless steel press ring, expansion can still maintain certain pressure on the slow-wave part, and therefore relative positions of all parts of the slow-wave part do not change. Meanwhile, the pressure will not enable the slow-wave part to deform and in addition, a spiral line can be well clamped. The qualification rate of brazing of the slow-wave part and the radiating effect of the slow-wave part are improved.
Description
Technical field
The utility model relates to a kind of microwave device and manufactures soldering frock, in particular a kind of brazing tooling of composite pipe shell slow wave parts.
Background technology
Travelling-wave tubes is in Modern Satellite communication, satellite navigation, day by day demonstrates the effect of not replacing in as electronic jamming device, prior-warning plane, fire control radar, accurate guidance especially at military electronics equipment.Slow wave parts are vitals of travelling-wave tubes, and number of spare parts is many, weld seam is many, parts are long.Along with improving constantly of travelling-wave tubes power, heat dissipation problem has just become a difficult problem for necessary solution, has designed a kind of slow-wave structure of composite pipe shell at present in high power travelling wave tube, and this structure has effectively solved slow wave heat radiation.Slow wave brazing tooling in the past adopts briquetting or mostly with support and screw fixation method, after soldering, can guarantee good concentricity and fitted position, but this structure can not be applicable to the soldering of composite pipe shell slow-wave structure, because composite pipe shell has higher requirement to brazing quality, requirement can also be wanted to play to helix slow-wave the effect of good clamping assembling in soldering.Therefore be badly in need of having designed a set of brand-new brazing tooling for the production of composite pipe shell slow-wave structure.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of brazing tooling of composite pipe shell slow wave parts is provided, and when guaranteeing concentricity and fitted position, realizes slow wave parts are better clamped.
The utility model is achieved through the following technical solutions, the utility model comprises bracket base, support pressing plate, bracket upright post, positioning base, location briquetting, pressure ring and sleeve, described positioning base is arranged on bracket base, support pressing plate is set in bracket upright post by securing member, the bottom of slow wave parts is arranged on positioning base, jacket casing is connected on slow wave parts, pressure ring is set on sleeve, on support pressing plate, offer guide rail hole, location briquetting is arranged at the top of slow wave parts through guide rail hole.
As one of optimal way of the present utility model, described securing member is nut, and bracket upright post is provided with screw thread, and nut and bracket upright post are used in conjunction with.
As one of optimal way of the present utility model, described bracket base is provided with locating slot, and the bottom of positioning base is arranged in locating slot.
Described bracket base, support pressing plate, bracket upright post, positioning base, location briquetting, pressure ring and securing member are stainless steel and make, and described sleeve is that molybdenum is made.
The utility model has the following advantages compared to existing technology: the utility model had both guaranteed the rigging position between each parts of slow wave parts, and in the process of soldering, rising because of temperature, stainless steel pressure ring outside slow wave parts and molybdenum sleeve meeting thermal expansion, because of molybdenum sleeve lower than the coefficient of expansion of stainless steel pressure ring, so expand, remain to slow wave parts certain pressure, relative position between each part of slow wave is not changed, this pressure can not make slow wave part distortion yet and helix is well clamped simultaneously, the qualification rate of slow wave parts solderings and the radiating effect of slow wave parts have been improved.

The specific embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented take technical solutions of the utility model under prerequisite; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, Figure 2 and Figure 3, the present embodiment comprises bracket base 1, support pressing plate 2, bracket upright post 3, positioning base 5, location briquetting 9, pressure ring 7 and sleeve 8, described positioning base 5 is arranged on bracket base 1, support pressing plate 2 is set in bracket upright post 3 by securing member 4, the bottom of slow wave parts 6 is arranged on positioning base 5, sleeve 8 is socketed on slow wave parts 6, pressure ring 7 is set on sleeve 8, on support pressing plate 2, offer guide rail hole, location briquetting 9 is arranged at the top of slow wave parts 6 through guide rail hole.
The securing member 4 of the present embodiment is nut, and bracket upright post 3 is provided with screw thread, and nut and bracket upright post 3 are used in conjunction with.
The present embodiment bracket base 1 is provided with locating slot, and the bottom of positioning base 5 is arranged in locating slot.Can guarantee accurate positioning, in brazing process, can not be offset.
The bracket base 1 of the present embodiment, support pressing plate 2, bracket upright post 3, positioning base 5, location briquetting 9, pressure ring 7 and securing member 4 are 1Cr18Ni9Ti stainless steel and make, and described sleeve 8 is made for molybdenum.
The assembling process of the present embodiment is as follows:
In process at slow wave parts 6 in soldering, rising because of temperature, all can there is thermal expansion in slow wave parts 6, pressure ring 7, sleeve 8, but the thermal coefficient of expansion of sleeve 8 is less than the thermal coefficient of expansion of pressure ring 7, at brazing temperature lower sleeve 8 and pressure ring 7, can give the certain pressure of slow wave parts 6 all the time, relative position between each part of slow wave is not changed, and this pressure is also firmly fixed helix slow-wave and the supporting rod of slow wave clamping simultaneously.
