The flip-out two-axis turntable based on the electric push rod

Abstract

The invention discloses a novel two-axis turntable based on an electric push rod. System, one end of the sinking reversing frame is hinged on the support platform, and is fixedly connected with the upper telescopic end of the electric push rod, the lower end of the electric push rod is fixed at an inclination angle with the supporting platform, and the upper part of the sinking reversing frame is provided with a slewing system The slewing system is mechanically connected with an adapter for supporting and fixing the satellite and can drive it to turn. The anti-overturning device is hingedly connected to one end of the support platform that flips out the satellite to prevent the satellite from overturning when it is turned out of the support platform. Compared with the prior art, the present invention uses an electric push rod device to realize the eversion of the two-axis turntable, provides technical guarantee for the deployment test of the landing buffer mechanism, and satisfies the assembly operation requirements for the deployment test of the buffer mechanism.

Description

technical field [0001] The invention belongs to the field of spacecraft attitude adjustment tooling, and in particular relates to an eversion-type two-axis turntable using an electric push rod to realize the adjustment of the attitude of the spacecraft. Background technique [0002] The dry weight of a certain satellite is about 1350Kg. During the test of the landing buffer mechanism, the satellite needs to be tilted from a vertical state to a certain angle, and then rotate around the satellite axis. In this process, the attitude adjustment of the existing satellite products is completed with the help of a two-axis turntable, and the satellite carried by the turntable can realize 0-90° flip and 0-360° rotation, and perform satellite attitude in these two directions control. [0003] At present, the two-axis turntable used in the field of domestic spacecraft assembly completes the turning action through the structure of the screw slide rail. The structure is shown in the sch...

AI Technical Summary

Problems solved by technology

Among them, the screw slide rail structure realizes the flipping of the satellites on the two-axis turntable through the crank slider mechanism. The maximum orbiting diameter of the satellite product is about 4m, and the maximum orbiting diameter of this satellite is nearly 5m, so the structure can no longer meet the diameter requirement of the star orbiting

In addition, the traditional screw-slider mechanism is used to carry the satellite on the turntable. Due to the structural characteristics, the satellite body is all placed on the turntable. After the turntable carries the satellite, it is bound to be raised as a whole, which is difficult to meet the requirements of convenient assembly and operation.
