Double-shaft rotating table for adjusting satellite postures

Abstract

The invention provides a double-shaft rotating table for adjusting satellite postures, which is used for the purposes of satellite assembly, test, experiment and the like. The rotating table comprises a rotating table body and a position pitching system, wherein the table body is provided with a driving wheel group so that the rotating table can flexibly move and is more convenient to use. The weight is lowered due to the adoption of the form of a slider-crank mechanism. A large portion of pressure is bore by guide rails, and the burden of a pitching pivot is lowered. Besides, a lever transmission mode is adopted, the pressure of a pitching motor and a speed reducer is largely reduced, and the bearing capability of the rotating table is improved. As a connecting rod in the slider-crank mechanism is used as the pitching system, the pitching pivot moves along an arc relatively to the table body with the variation of a pitching angle, and the arc takes the length of a crank as a radius. When the pitching angle is 0, the height of the pitching pivot is in a lowest position, so that the height of the whole equipment is lowered, and occupation space is reduced, thus facilitating storage. Transition rings are designed, different types of satellites are fit through the change of the transition rings, universality is improved, and resources are saved.

Description

technical field [0001] The invention is a satellite attitude adjustment two-axis turntable used for satellite assembly, test and experiment. Background technique [0002] The level of aerospace science and technology reflects the comprehensive strength of a country. At present, all major countries in the world are scrambling to develop into the space field. As a product of aerospace technology, various artificial satellites can not only provide convenience for human life, but also for a The military strategic position of the country is of great significance. [0003] With the continuous growth of our country's economy and the continuous improvement of comprehensive national strength, in order to safeguard the interests of the country and maintain the status of a big country, our country's demand for various satellites is also increasing. Before the satellite is launched into space, it needs to carry out assembly, joint debugging, testing and experiment work on the ground. A...

AI Technical Summary

Problems solved by technology

[0005] (1) Basically, no driving wheels are installed, the movement is not flexible, and it is very inconvenient to use

[0006] (2) The pitch shaft of the turntable is fixed relative to the table body. This structure makes the shaft bear a large pressure, which is not good for the shaft, and brings a lot of pressure to the drive unit, and the load is limited; due to this structural limitation, the The turntable is large in size, heavy in weight, and takes up a lot of space

[0007] (3) At present, with the end of the final assembly task of fixed-type satellites, the turntable will be eliminated, and the versatility is very poor, resulting in a waste of resources
