Abstract

The invention provides a large-diameter inflation warp-direction rib antenna detecting device, and belongs to the field of detecting tools. The large-diameter inflation warp-direction rib antenna detecting device resolves the problem that an existing large-diameter inflation warp-direction rib antenna is inconvenient to detect. The large-diameter inflation warp-direction rib antenna detecting device comprises a base, a stand column, a sleeve, a precise bearing pack, a truss, supports, a sliding rail, a sliding block and a telescopic rod; the base is horizontally arranged; the stand column is arranged on the base and perpendicular to the base; the lower end of the stand column is sleeved with the sleeve and fixedly connected with the sleeve, and a plurality of right-triangle reinforcing boards are arranged on the periphery of the sleeve; the precise bearing pack is connected with the stand column and the truss which is perpendicular to the stand column; the two supports are correspondingly arranged between the outer ends of two sides and the midpoints of the two sides; the sliding rail is fixedly connected above the truss, and the direction of the sliding rail and the direction of the truss are consistent; the sliding block is arranged inside the sliding rail; the lower end of the telescopic rod is fixedly connected with the upper end of the sliding block, and the upper end of the telescopic rod is tapered. The large-diameter inflation warp-direction rib antenna detecting device is used for detecting the precision degree of the paraboloid of the large-diameter inflation warp-direction rib antenna.

Description

technical field [0001] The invention belongs to the field of detection tools, and in particular relates to a detection device for large-diameter air-filled meridional rib antennas. Background technique [0002] The accuracy of the paraboloid of the satellite antenna determines the accuracy of the focusing signal. The inflatable meridional rib antenna is a kind of satellite antenna. Since the outer ends of the ribs are connected by soft connections, the shape of the ribs in the production process And the position is easy to change, especially the long ribs of the large-diameter inflatable meridional rib antenna, the change is more obvious, making the parabola inaccurate, so the ribs must be repeatedly inspected and trimmed before they can be put into use . The current detection method is an optical detection method. The detection is completed through multiple processes such as pasting multiple photosensitive targets, taking multiple photos, and complex calculations. The dete...
