Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings, but this is only exemplary and not intended to limit the protection scope of the present invention.

[0036] Such as figure 1 As shown, the whole process of satellite structure docking based on laser level calibration is as follows:

[0037] 1) Check that the pod body 4 and the satellite fixed cabin body 7 are respectively parked on their respective racks, and the final assembly work before docking has been completed, and the conditions for docking are met;

[0038] 2) Paste three to four size scale references 5 at the position of the docking surface of the pod body 4 and the satellite fixed cabin body 7; Towards the laser level 3, the sticking position of the scale reference of the satellite fixed cabin body 7 is to face the laser level 6, so that the horizontal laser synchronous projection of the laser level is advisable;

[0039] 3) Set the laser level 6 t...

Abstract

The invention discloses a satellite cabin hoisting and docking method based on correction of a laser level. The method comprises the following steps of measuring and monitoring the levelness of a satellite cabin docking surface and a rack car docking surface by means of the laser level; moving a lifting point to the position above the center of gravity of a hung object to make sure that the docking surface below the hung object is parallel to the natural horizontal plane by means of guidance of a tilt angle sensor of an automatic balance crane and the laser level; and finally, docking the hungcabin and a parking cabin in a horizontal plane determined by common reference of the laser level. The method disclosed by the invention improves the docking and assembling efficiency of a satellitestructure, controls the quantified docking indexes, and meets the posture demand in docking the satellite structure.

Description

technical field [0001] The invention belongs to the technical field of satellite assembly, and specifically relates to a method for hoisting and docking a satellite cabin by using an automatic level adjustment spreader, a laser level and a lifting platform. Parking and stable docking requirements meet the high-precision assembly requirements of large-scale satellite structures in the hoisting state. Background technique [0002] With the development trend of large-scale satellite products, compact layout, and quantitative quality control, the quality control and process index quantification work requirements in the process of docking and final assembly of satellite cabins are becoming more and more important. The cabin docking precision control system is required to realize the satellite docking process. Attitude adjustment in order to meet the precision control requirements during the docking process of the satellite cabin. [0003] At present, in order to meet the high-pr...
