Embodiment Construction

[0038] During the installation of the solar wing, it is necessary to press each piece of the solar wing on the side plate of the satellite through the pressing rod 4, such as figure 2 As shown, the three sections of the solar wing are compressed on the side of the satellite body, and the compression nut 5 provides a certain pre-tightening force for the compression rod 4 through threaded connection, and the pre-tightening force of the compression rod 4 needs to be precisely controlled at a reasonable In the range. When the compression nut 5 is manually tightened, though the pretightening force can be controlled within a certain range by controlling the number of tightening turns. However, due to the friction between the compression nut 5 and the surface of the workpiece to be pressed, it greatly affects the size of the preload force of the compression rod 4 . Therefore, it is difficult to precisely control the pretightening force within a reasonable range by manually turning ...

Abstract

The invention relates to a device for automatically pre-tightening a solar wing pressing rod. The device comprises a pressing rod clamping mechanism, a stretching mechanism, a nut tightening mechanismand a rechargeable battery, wherein one end of the pressing rod clamping mechanism is used for clamping an external pressing rod, and the other end of the pressing rod clamping mechanism is fixedly connected with the stretching mechanism; the stretching mechanism stretches the pressing rod clamping mechanism towards the outer side of a satellite side plate along an axis of the external pressing rod, so that the pressing rod has pre-tightening force; the nut tightening mechanism is used for tightening a pressing nut on the pressing rod to press and fix a solar wing on the satellite side plate.The device provided by the invention can completely realize the automation of stretching the pressing rod and tightening the tightening nut and avoid the influence of human factors on the control accuracy of the pre-tightening force control to a maximum extent.

Description

technical field [0001] The invention relates to a device for automatic preloading of a solar wing pressing rod, in particular to a device that can automatically provide preloading force during the pressing operation of a solar wing of a spacecraft, and belongs to the technical field of precision assembly and adjustment of a space expandable mechanism . Background technique [0002] At present, in the process of installing the solar wing, each solar wing panel needs to be pressed against the side wall of the satellite through a compression rod and a compression nut. In order to ensure that the solar wing is reliably pressed against the side wall of the star during launch, the preload of the compression rod needs to be accurately controlled within a reasonable range. The existing compression scheme is to use two lengthened compression wrenches, wherein the first compression wrench is inserted into the end of the compression rod, and the second compression wrench is inserted i...
