Abstract

The invention discloses a main reflector interchange structure of a satellite communication earth station antenna and a technology for the main reflector interchange structure. The main reflector interchange structure comprises an overall antenna head, wherein the overall antenna head comprises main reflector panels, a center body, radiation beams, truss pull rods, connection plates and installation holes. According to the technical main points, the radiation beams are surrounded by the truss pull rods, are connected with and arranged on the center body through bolts and locating taper pins, are arranged at equal intervals and surround the center body for a circle; a center surface formed by various support lugs of the radiation beams and the center shaft of the center body are on the same surface; molded drilling is adopted by all installation holes in the main reflector panels, the center body and the radiation beams, so that the consistency of the installation holes and the precision of hole sites and hole diameters are ensured; the main reflector panels are formed by mold drawing and are assembled, riveted and molded by adopting a tooling clamp, the radiation beams are molded, processed and produced by adopting a setting mold, and the truss pull rods are processed and produced by adopting the setting mold, so that main reflector interchange is achieved through improvement of these processes.

Description

Technical field [0001] The invention relates to the technical field of satellite communication, in particular to an interchange structure of the main reflection surface of a satellite communication earth station antenna and its process. Background technique [0002] In the manufacturing process of satellite communication antenna manufacturers, the accuracy of the main reflecting surface of the antenna is regarded as the top priority of product quality. The accuracy of the main reflection surface of the split-lobe assembled satellite communication antenna is mainly guaranteed by the difference of the root mean square value of the measurement surface. The root mean square value difference of the single-lobe main reflector must be controlled to not less than 0.03mm, and the root mean square value difference of the final assembly must be controlled to not less than 0.05mm to ensure that the radio frequency index of the antenna meets the network access requirements of the satellite co...
