An umbrella-shaped antenna metal mesh surface holding sewing device

Abstract

The invention discloses an umbrella-shaped antenna metal mesh face maintaining and sewing device, and relates to the technical field of antenna mechanisms. The umbrella-shaped antenna metal mesh facemaintaining and sewing device includes a first supporting piece, a second supporting piece, a first simulation rib, a second simulation rib, a first transverse beam, a second transverse beam, a thirdtransverse beam, a fourth transverse beam and a fifth transverse beam; the first simulation rib and the second simulation rib are arranged to form an included angle, the first transverse beam, the second transverse beam, the third transverse beam, the fourth transverse beam and the fifth transverse beam are fixedly mounted between the first simulation rib and the second simulation rib in sequence,and the first transverse beam is fixedly mounted at the included angle end of the first simulation rib and the second simulation rib; and the fifth transverse beam is fixedly mounted at the includedangle end of the first simulation rib and the second simulation rib, a first supporting piece is fixedly and vertically mounted at the bottom end of the first transverse beam, and the second supporting piece is fixedly and vertically mounted at the bottom end of the fourth transverse beam. According to the umbrella-shaped antenna metal mesh face maintaining and sewing device, the mesh face tensionis uniform, the shape difference of the mesh face of each sector is low, and the mesh face tension of the mesh face after sewing is within the reasonable range of the designed mesh face tension.

Description

technical field [0001] The invention relates to the technical field of antenna mechanisms, in particular to an umbrella-shaped antenna metal mesh surface holding sewing device. Background technique [0002] Since the umbrella-shaped deployable antenna has good electrical performance, it requires high mesh surface accuracy and good tension uniformity; it has a wide range of applications in the field of antennas. [0003] However, in the traditional sewing process of the umbrella-shaped expandable antenna, the method of manual hand sewing is basically used; this method has great disadvantages, as follows: [0004] (1) Uneven mesh surface tension; [0005] (2) There are large differences in the shape of the mesh surface of each sector; [0006] (3) After the mesh surface is sewn, the mesh surface tension is not within the reasonable range of the designed mesh surface tension. Contents of the invention [0007] The purpose of the present invention is to overcome the above-m...
