Composite material radome arc flange interface hole machining clamp and machining method

The invention discloses a composite radome arc-shaped flange interface hole machining clamp and method. The composite radome arc-shaped flange interface hole machining clamp comprises a drilling clamp and a special countersinking tool. The drilling clamp is composed of a positioning plate used for positioning during drilling and a drilling sleeve used for position guiding in the drilling process, the thickness of the positioning plate is 3 mm, an antenna housing is arranged on the top of the positioning plate, and the appearance of the positioning plate is matched with an oval pit in the bottom of the antenna housing. A drilled hole is positioned and guided through the drilling clamp, accurate drilling is conducted on an arc-shaped flange interface of the radome according to the required position, then the guide part of the special countersinking tool is inserted into the drilled hole, the countersinking tool guide column part is used for limiting and guiding, and the countersinking tool body blade part is us
