Mounting and centering device of rocket body

Abstract

The invention provides a mounting and centering device of a rocket body. The mounting and centering device comprises a rocket clamping and fixing mechanism and a rocket fixing end mechanism, wherein the rocket clamping and fixing mechanism is adjacent with the rocket fixing end mechanism; the rocket fixing end mechanism comprises a six-dimensional parallel mechanism, a front end rocket centering mechanism and a tail end rocket fixing mechanism; one end of the six-dimensional parallel mechanism is hinged to the tail end rocket fixing mechanism, and the other end of the six-dimensional parallel mechanism is hinged to the front end rocket centering mechanism. The mounting and centering device has the characteristics that by adopting the six-dimensional parallel mechanism, the rocket body can be quickly positioned and mounted in the mounting process; the six-dimensional parallel mechanism has the advantages of high rigidity, high speed, strong carrying capability, small error, high precision, good power property, easy control and the like.

Description

technical field [0001] The invention relates to a centering assembly of a rocket, in particular to an installation and centering device for a rocket body. Background technique [0002] With the rapid development of my country's aerospace industry, the aerospace manufacturing industry has ushered in a period of opportunity for leapfrog development. As an important link in spacecraft manufacturing, spacecraft assembly determines the production capacity of spacecraft. Today, various spacecraft emerge in endlessly.

[0003] After searching the prior art, it is found that the application number is 201410387922.2, and the name is rocket body. The automatic positioning and centering device has the following disadvantages: 1. The device cannot adjust the angle of the rocket body axis, and is only limited to the alignment of the axis; 2. The structure of the rocket load-bearing frame of the device is too thin, which is prone to strength damage; 3. The rocket is fixed behind the device without additional fixing devices, which is prone to cause sliding and rotation, which reduces the efficiency of installation and adjustment; 4. The device is in the The misalignment of the space axis cannot be assembled effectively
