波导管与法兰盘钎焊时,传统的方法是将波导管与法兰盘搭接处在铣床上铣出直口,法兰盘靠直口定位然后进行钎接,或不通过铣床加工,借助工夹具来保证其装配尺寸,但用上述两种方法进行显得即不经济,又复杂化。我厂生产的波导馈源器件有长2500、1600两种,由于法兰盘与波导管为间隙配合钎焊,间隙为单面0.1mm定右,而且有严格的垂商度要求,通过试验,对以上两种定位方法进行了改进,见图所示结构。即先在波导管接头处用直角尺划线(保证其露出长度及垂直度。)然后在四角处用小凿子打出豁口,如图所示。法兰盘的装配要靠紧四角豁口出现的肩台,然后钎接。钎焊后的波导 Waveguide and flange brazing, the traditional method is to take the waveguide and flange lap at the milling machine milling straight mouth, flange straight mouth positioning and then brazing, or not through the milling machine, With the fixture to ensure the size of its assembly, but the above two methods are uneconomical and complicated. I produced the waveguide feed device has a long 2500,1600 two, due to the flange and the waveguide with the gap with brazing, clearance for the single side of 0.1mm right, and there is a strict vertical business requirements, through the test, The above two positioning methods have been improved, as shown in the figure structure. That is, first at the waveguide joints with a rectangular ruler (to ensure that the exposed length and verticality.) And then use a small chisel in the four corners play a gap, as shown. Flange assembly depends on the tight shoulder appears shoulder, and then brazing. Brazed waveguide
