Abstract
The utility model discloses an anti-deformation clamp for planar antenna brazing. The anti-deformation clamp comprises a fixing component, a pressing plate and a plurality of spring screw components. The fixing component is used for placing an assembled to-be-brazed planar antenna. The pressing plate is placed on the upper surface of the to-be-brazed planar antenna. The shape of the pressing plate is matched with that of the to-be-brazed planar antenna. The spring screw components are disposed on the fixing component and used for tightly pressing tightening points on the pressing plate to allow the pressing plate to be tightly pressed and attached to the upper surface of the to-be-brazed planar antenna. Thermal expansion difference between the clamp and the planar antenna can be controlled and eliminated by adjusting compression amount of a high-temperature spring at high temperature to reduce deformation after brazing, and accordingly deformation resistance of the brazed planar antenna is achieved, and high-quality one-step brazing of the planar antenna can be completed efficiently and precisely.
Description
Technical field
The utility model relates to a kind of anti-deformation fixture, is specifically related to a kind of anti-deformation fixture of complicated plate aerial soldering of structure that is applied to.
Background technology
Common wall waveguide battle array and feed waveguide welding fabrication that plate aerial is comprised of the thick radiation cover plate of 0.8～1mm, dividing plate, base plate etc.Such antenna structure is complicated, is made of multilayer, both at home and abroad this product is shaped with digital control processing usually at present, adopts several welding manners such as salt bath weldering, vacuum brazing to carry out integral solder after the assembling.There is series of problems in the manufacture method of this plate aerial of prior art in manufacturing process, especially the combination brazing process of antenna.Because waveguide is as the microwave transmission passage, it has very strict sectional dimension, the requirement of form and position tolerance, the brazed seam of not burn-oning and the buckling deformation in cross section more can not be arranged, improper phase place and the standing wave that all can affect plate aerial of any processing is so seem particularly important to the Deformation control in the brazing process.
The material of plate aerial adopts aluminium alloy, and the anchor clamps that are used for the dull and stereotyped electric wire of fixed clamp in brazing process then generally adopt stainless steel material to make.Because the linear expansion coefficient of aluminium alloy and stainless steel material has a long way to go, the aluminium alloy average coefficient of linear expansion is 25 * 10
-6/ K, and the stainless steel average coefficient of linear expansion is 18 * 10
-6/ K.So huge linear expansion coefficient difference very easily causes the distortion of antenna in the situation of high temperature.
Described soldering anti-deformation fixture for plate aerial can adopt following two kinds of structures to realize in the prior art.The first is to use the imposed deformation anchor clamps of screw in compression formula, and as shown in Figure 1, these anchor clamps comprise: upper mounted plate 4, bottom plate 5, pressing plate 7 and some pinching screws 10.Be fixedly connected with nut 3 by double-screw bolt 2 between wherein said upper mounted plate 4 and the bottom plate 5.The plate aerial to be brazed 6 that assembles is placed on the end face of bottom plate 5 with this as datum level, and described pressing plate 7 is placed on the upper surface of plate aerial 6, and the shape of this pressing plate 7 is the designs that match of the upper surface shape according to plate aerial 6.Further according to the upper surface shape of described plate aerial 6 and the shape of pressing plate 7, determine screw in compression point position, and the corresponding position on upper mounted plate 4 installs some pinching screws 10, compresses the comparatively complicated every aspect of plate aerial 6 upper surfaces by tightening described pinching screw 10.
But in brazing process, adopt the clamp plate aerial of said structure, have the following disadvantages and limit.At first, because the formation number of plies of plate aerial is more, existence distortion in various degree after each layer parts are finished by digital control processing, adopt the imposed deformation anchor clamps of screw in compression formula without any the elastic space of regulating, extremely difficult the assurance simultaneously of each pinching screw fitted to the compression of plate aerial upper surface.Secondly, because under high-temperature condition, the expansion of plate aerial is very serious, the subregion can produce moderate finite deformation, and the subregion can produce the situation of rosin joint, therefore will directly cause the brazing quality of plate aerial to be guaranteed.
The second anti-deformation fixture of the prior art is the structure that adopts the weight compression formula, and as shown in Figure 2, it comprises bottom plate 5 and deadweight briquetting 7.The plate aerial to be brazed 6 that assembles is placed on the end face of bottom plate 5 with this as datum level, described deadweight briquetting 7 is placed on the upper surface of plate aerial 6, the shape of this deadweight briquetting 7 is the designs that match of the upper surface shape according to plate aerial 6, is used for directly compressing the comparatively every aspect of complexity of plate aerial 6 upper surfaces.
Although the anchor clamps of described employing weight compression formula can avoid the first to adopt the defective of the imposed deformation anchor clamps of screw in compression formula, it still exists following shortcoming and restriction.At first, the anchor clamps of this weight compression formula are only applicable to the comparatively plate aerial of simple flat of surface structure, and for the comparatively complicated plate aerial of surface structure, the anchor clamps of weight compression formula are in fit on difficulty comparatively, and it is unsatisfactory to cause compressing effect.Secondly, because the anchor clamps of weight compression formula are comparatively responsive for vibrations, in the brazing process of plate aerial, slight vibrations namely can have influence on welding quality.The 3rd, because the deadweight briquetting is set, therefore the weight and volume of whole anchor clamps is larger, has prolonged the time of welding procedure; And in stove, take than large space, reduced the batch of product, cause production efficiency obviously to reduce.
