Rapid hole returning device and method for narrow space of radar radome

Abstract

The invention belongs to the field of radar radome machining, and specifically relates to a rapid hole returning device and method for a narrow space of a radar radome. The inner space of a radar radome product is narrow, a male die is adopted for forming, drilling cannot be conducted from inside to outside, and the hole returning precision of drilling from outside to inside is low. The hole returning device comprises a reference rod fixedly installed on the end portion of a sliding rail and a calibration rod installed on the sliding rail in a sliding mode, the reference rod and the calibration rod are perpendicular to the sliding rail, two stages of telescopic rods and a pressing screw rod are installed on each of the reference rod and the calibration rod, the pressing screw rods are opposite, and a reference pen is inwards installed on the outer end portion of the corresponding telescopic rod of the reference rod. An elastic line drawing pen is inwards installed on the outer end portion of the corresponding telescopic rod of the calibration rod. By adjusting the extension length of the reference pen and the telescopic rods on the calibration rod, a calibration column can penetrate through a sleeve of the reference pen and a sleeve of the elastic line drawing pen at the same time and be positioned, and therefore inner and outer hole site alignment is achieved. The problem that holes cannot be formed or the hole forming precision is low in the assembling and manufacturing process of the radar radome is solved.

Description

technical field [0001] The invention belongs to the field of radome processing, and in particular relates to a fast hole-returning device and method used in a narrow space of a radome. Background technique [0002] see figure 1 , at the position of the inner lower edge of the radome 25, metal connectors usually need to be installed, including the middle connector 26 including lock seats, pin seats and / or angle pieces, etc. and inner ring 27, for connecting the radome 25 to the aircraft The body is connected. Middle connectors 26 such as lock seat, pin seat and / or angle piece are positioned between inner ring 27 and radome 25, after inner ring 27 is installed on the lower surface of middle connector 26, the connecting hole on the middle connector 26 is closed. The inner ring 27 is completely covered and invisible from one side of the outer surface of the inner ring, so tools such as ordinary air drills and angle air drills cannot be used to accurately drill holes from the o...
