Method for processing three dimensional spatial structure assembly hole of antenna housing through special drilling rig

Abstract

The invention discloses a method for processing a three dimensional spatial structure assembly hole of an antenna housing through a special drilling rig. The method for processing the three dimensional spatial structure assembly hole of the antenna housing through the special drilling rig includes that milling an outer conical molded surface, an inner conical molded surface and false bosses in sequence, wherein the angle between the outer lateral surfaces of the false bosses at the two sides is equal to the angle between the central lines of two rows of pre-processing assembly holes of the special drilling rig. The processing for the three dimensional spatial structure assembly hole of the antenna housing through the special drilling rig is realized through the false bosses, the processing difficulty is lowered, the production efficiency is improved, and the precision of the assembly hole is guaranteed; the assembly hole processing precision is high, and the product design precision requirement is completely satisfied.

Description

technical field [0001] The invention relates to a processing method of a conical inclined hole, in particular to a processing method of a three-dimensional space structure assembly hole of a special drilling tool for radome. Background technique [0002] In aerospace production, it involves a heat-resistant and wave-transparent radome. Its structure includes three-dimensional space structure assembly holes, and the outer surface is conical. There are higher size requirements and shape requirements between the three-dimensional space structure assembly holes. Require. As a key component of the aircraft fairing, the wave-transparent radome has the characteristics of small size and compact structure, which affects the flight performance of the aircraft. In order to ensure the processing accuracy of the three-dimensional space structure assembly holes of this type of radome, special drilling tools are generally used for drilling, and the processing accuracy of the holes on the ...

Problems solved by technology

In addition, since the structure of the special drilling tool is a conical surface, there is no positioning reference during the processing of the assembly hole, which adds greater difficulty to the processing of the assembly hole

For the processing of assembly holes of such three-dimensional space structures, the common method is to use a turning head or a dividing head on an ordinary CNC milling machine. This processing method is more complicated, the processing efficiency is low, and the accuracy cannot be guaranteed.

Usually through the five-axis machining center, complex coordinate calculation and high-precision equipment configuration are used for processing. Due to many factors involved, the processing accuracy is relatively low and the processing cost is high.
