Description

[0001] The present invention relates to the field of antenna cover processing, and in particular to a device for integrated processing of inner and outer surfaces of a special-shaped antenna cover and a method for using the device. Background Art

[0002] The radome is a barrier that protects the seeker echo antenna from the influence of the external environment during high-speed flight. Its processing quality directly affects the guidance accuracy of the missile and improves the aerodynamic performance of the missile. Currently, special-shaped (non-rotating) ceramic radomes are commonly used in missiles.

[0003] Traditional special-shaped ceramic radomes are typical difficult-to-process complex components. They have no clear processing datum features. The internal woven fiber layer is easily damaged during processing, and the electrical thickness of each part of the radome wall must be consistent, so high requirements are placed on the uniformity of the wall thickness. As a result, it is extremely difficult to process special-shaped ceramic radomes. Currently, three-axis or five-axis linkage machine tools are mainly used for processing, but the processing requirements are high. When ordinary machine tools are used for processing, the processing datum of the special-shaped ceramic radome cannot be kept unchanged during processing, so high processing accuracy cannot be achieved.

[0004] How to process special-shaped ceramic antenna cover blanks without the need for three-axis linkage automated machine tools, keep the processing datum unchanged during the process, and achieve high processing accuracy has become an urgent problem in this field. Summary of the invention
