摘要
某雷达高精度的高通滤波器,结构复杂,采用常规的机械加工方法无法实现,必须将其分解成几个结构件分别加工,再将其连接成腔体。提高各部件的接触面尺寸及形位精度,设计合适的焊接结构及装配定位结构,采用真空铝钎焊的方式实现高精度连接,满足其结构设计要求。
The high - pass filter of one high - accuracy radar can not be processed with normal machining method because of the complicated structure, and the manufacture of the high - pass - filter has to be divided into several parts. Then restructure the filter after each part processed. It is important to exact the precision of the contact surface dimension of each part and the dimension of position and figure. Design for welding and the assembly position structure are also very important. The figure will not change after welded with vacuum AL- brazing. It meets the needs for structure performance.
