High-precision mass center adjusting system suitable for on-orbit satellite

The high-precision mass center adjusting system comprises a first mass center adjusting mechanism, a second mass center adjusting mechanism, a third mass center adjusting mechanism, a fourth mass center adjusting mechanism, a fifth mass center adjusting mechanism and a sixth mass center adjusting mechanism, and the satellite in each degree-of-freedom direction can use two mass center adjusting mechanisms to work; and a mass block is arranged in each mass center adjusting mechanism, and the mass blocks are mounted on the sliding guide rails. The system has the advantages that the mass center adjusting mechanism system is arranged, and the sliding lead screw is controlled to adjust the position of the mass block on the sliding guide rail, so that high-precision mass center adjustment of an on-orbit satellite is achieved. 本发明公开了一种适用于在轨卫星的高精度质心调节系统，包括质心调节机构一、质心调节机构二、质心调节机构三、质心调节机构四、质心调节机构五、质心调节机构六，每个自由度方向卫星可以使用两个质心调节机构工作；每个质心调节机构内部设置一个质量块，质量块安装在滑动导轨上。本发明优点在于通过配置质心调节机构系统，并控制滑动丝杠来调节质量块在滑动导轨的位置，以实现在轨卫星的高精度质心调节。
