Abstract

In order to solve the problem that high-precision simultaneous locking cannot be achieved among satellite solid-plane antenna modules, the invention provides a locker which can achieve simultaneous locking of multiple sets of antenna reflecting surfaces, compensate for errors within a certain range and ensure the precision after locking, and achieves repeated folding, high-precision unfolding andlocking of a solid-plane reflecting surface antenna. Locking of the locker in the upper direction, the lower direction, the front direction, the rear direction, the left direction and the right direction is achieved by arranging a spring bolt divided into two parts and assembled together and the pressing block in the pressing block sliding groove in the spring bolt sliding groove, errors can be compensated within a certain range, the precision after locking is guaranteed, and high-precision locking between the two solid-surface reflector antennas is further achieved.

Description

technical field [0001] The invention relates to the technical field of satellite antennas, in particular to a multi-module self-adaptive high-precision locking device. Background technique [0002] With the development of satellite technology, more attention has been paid to the design requirements of multi-band, high precision and large capacity in the design of satellite antennas, and the design of satellite antennas has gradually become more complicated. However, due to the limitations of rocket carrying capacity, economy and other factors, the antenna structure needs to be light in weight and small in size. Based on the above contradictions, modular and expandable antenna technology has emerged and developed rapidly, and has become an important way to solve the needs of satellite antennas such as large aperture, high precision, and light weight. This requires the antenna to be in a folded state when launching, and to unfold after launching to the orbit. Therefore, the a...
