Automatic rocket tube section assembling system based on planar 3-PRR parallel structures

Abstract

The invention provides an automatic rocket tube section assembling system based on planar 3-PRR parallel structures, frame chassis assemblies are perpendicular to rails, and pulleys are arranged at the two ends of the frame chassis assemblies correspondingly, placed on the rails, and slide along the rails; three PRR structures are arranged on the frame chassis assemblies in the direction of the frame chassis assemblies, namely the direction perpendicular to the rails, and the PRR structures are characterized in that branch chain driving motors are controlled by corresponding control cabinets to drive corresponding pinions to rotate, then big gear wheels meshed with the pinions are driven to rotate and drive push rods to move up and down in the vertical direction, one ends of connecting rods are rotationally connected with the push rods correspondingly, the other ends of the connecting rods are connected with the bottoms of rocket body arc-shaped brackets correspndingly, and the connecting rods are driven by the push rods to rotate the rocket body arc-shaped brackets; a rocket body hoop is arranged on the inner side surface of each rocket body arc-shaped bracket and used for encircling a rocket body; among the three connecting rods in each of the three PRR structures, two are arranged in parallel, and the other is arranged in axial symmetry with the parallel direction; Every twoframe chassis assemblies are used for supporting the two ends of each rocket tube section correspondingly.

Description

technical field [0001] The patent of the present invention relates to a mechanical device in the field of rocket assembly and manufacturing, especially an automatic attitude adjustment assembly system with a flat 3-PRR configuration. Background technique [0002] The rocket body of a launch vehicle is made up of multiple splicing segments. During the segment assembly process, the poses of the front and rear docking segments need to be adjusted to ensure the completion of the assembly. The attitude of the assembly section of the existing rocket assembly system is basically completed through manual assembly and driving adjustment. The assembly workload is large and the attitude adjustment ability is limited. The assembly quality depends on the experience of the assembly technicians, and the assembly efficiency is low and the assembly quality is reliable. Sexuality and other issues. Therefore, by developing an automatic attitude adjustment assembly system for launch vehicles, ...
