Method for assembling special-shaped curved radome cover body and connecting ring

Abstract

The invention discloses a method for assembling a special-shaped curved radome cover body and a connecting ring. The method comprises the following steps: 1) matching the connecting ring with a milling: fixing the connecting ring on an assembly fixture and positioning, matching a milling according to the actual size of the inner curved surface of the cover body, and machining the outer curved surface of the connecting ring, in which the cover body and the connecting ring are subjected to trial assembly until the outer curved surface of the connecting ring meets the fit clearance requirements;2) radome assembly: uniformly brushing and applying an adhesive onto the assembly surface of the outer curved surface of the connecting ring and the inner curved surface of the cover body, lifting thecover body with a cover body spreader, aligning an open end of the cover body with the connecting ring, slowly loading the cover body onto the connecting ring, and then fixing the cover body and positioning to fit the cover body in place. By adopting the method, not only is the assembly precision of the cover body and the connecting ring is ensured, but also the difficulty of matching milling andmachining on the assembly surface of the cover body and the connecting ring is reduced.

Description

technical field [0001] The invention relates to an assembly method of an antenna cover body and a connecting ring, in particular to an assembly method of a special-shaped curved surface antenna cover body and a connecting ring. Background technique [0002] In aerospace production, there is a heat-resistant, wave-transparent radome, which is Ω-shaped in shape and has a three-dimensional space structure, and its structure includes a cover body and a connecting ring. As a key component of missile radar fairing, the wave-transparent radome has the characteristics of large size and complex shape and structure. The connecting ring is a metal part, and the cover body is a non-metallic part. The connecting ring is assembled at the outlet end of the cover body to form a radome. Usually, the assembly surface of the connecting ring and the cover body is assembled by bonding with an adhesive, and the connecting ring and the cover body are assembled into a radome. After the radome, the...

However, for the special-shaped curved surface radome, the assembly surface of the cover body and the connecting ring are both special-shaped curved surfaces, and the special-shaped curved surface has no geometric center of rotation. Due to the lack of self-centering function, it is difficult to ensure the alignment between the cover body and the connecting ring during assembly. Coaxiality requirements; In addition, the assembly surface of the cover body and the connecting ring can only be milled to ensure accuracy, and it is difficult to ensure the matching accuracy between the special-shaped curved surfaces, which makes the cover body and the special-shaped curved surface radome and Connecting ring assembly poses many challenges
