Abstract

Изобретение относитс к антенной технике. Цель изобретени - повышение точности параболитической панели 1 и уменьшение габаритов стенда. При работе стенда каретка 8 вместе с размещенными на ней панелью 1 и ножевыми шаблонами 12 перемещаетс вдоль линии, а параболический ножевой шаблон 2 скользит по кромкам 13 шаблонов 12 и перемещаетс вертикально. Его выпукла рабоча кромка 3 образует над панелью 1 участок поверхности параболоида вращени - теоретической поверхности рефлектора. При механической обработке поверхности панели 1 на шаблоне 2 закреплена фреза с возможностью перемещени вдоль кромки 3. При контроле поверхности готовой панели 1 на шаблоне 2 установлен измеритель зазора между кромкой 3 и поверхностью панели 1. Перемещение рабочего инструмента по поверхности параболоида вращени обеспечиваетс путем взаимодействи плоских и взаимно перпендикул рных шаблонов 2 и 12, которое основано на свойстве параболоида вращени образовывать в каждом сечении плоскостью, параллельной его оси, исходную параболу. Даны ил.выполнени стенда дл изготовлени и контрол параболической панели как с вогнутой, так и с выпуклой поверхностью. 2 ил.The invention relates to antenna technology. The purpose of the invention is to improve the accuracy of the parabolic panel 1 and reduce the dimensions of the stand. When the stand is in operation, the carriage 8 together with the panel 1 and the knife templates 12 placed on it, moves along the line, and the parabolic knife template 2 slides along the edges 13 of the templates 12 and moves vertically. Its convex working edge 3 forms above the panel 1 a section of the surface of a paraboloid of rotation — the theoretical surface of the reflector. When machining the surface of panel 1, a milling cutter is fixed on template 2 and can be moved along edge 3. When monitoring the surface of finished panel 1, gauge 2 has a gap meter between edge 3 and surface of panel 1. The working tool moves along the surface of a paraboloid of rotation by mutually perpendicular patterns 2 and 12, which is based on the property of a paraboloid of rotation to form in each section a plane parallel to its axis, the original parabola. A performance test bench for the manufacture and control of a parabolic panel with both a concave and convex surface is given. 2 Il.
