Attitude adjustment assembly system and attitude adjustment method for docking of rocket components

Abstract

The invention provides a posture adjustment assembly system used for butt joint of components of a rocket. The posture adjustment assembly system comprises a posture adjustment system, a test system and a controller, wherein the posture adjustment system comprises first guide rails, beams and guide rail wheels, the guide rail wheels can move along the first guide rails through a horizontal moving mechanism, the posture adjustment system further comprises two posture adjustment devices arranged in parallel, each posture adjustment device is transversely arranged on the upper sides of the two first guide rails and is connected with the top faces of the beams, and each posture adjustment device comprises a supporting beam, a lifting table, a bracket support and an arc-shaped bracket. A posture adjustment method of the posture adjustment assembly system used for butt joint of the components of the rocket includes six steps. The posture adjustment system comprises the two posture adjustment devices, and the test system comprises an optical measurement device, measurement points located at the end of a rocket body and a processor. When only one single posture adjustment device is combined with the first guide rails, the guide rail wheels and the horizontal moving mechanism, four-freedom-degree posture adjustment can be achieved; when the two posture adjustment devices are used in cooperation with each other, six-freedom-degree posture adjustment can be achieved, and the two posture adjustment devices are independent, do not interfere with each other during six-freedom-degree adjustment and are matched with each other during adjustment.

Description

technical field [0001] The invention belongs to the field of mechanical assembly, and in particular relates to an attitude adjustment assembly system and an attitude adjustment method for rocket component docking. Background technique [0002] In the field of domestic aerospace manufacturing, the docking assembly of rocket sections still follows the manual operation and special tooling of the rocket body segmented assembly method decades ago, and the assembly coordination and section attitude adjustment rely on human vision and manual operation, respectively. The main process is: the rocket sections to be docked are placed on the docking frame respectively, and there is usually a circle of connecting holes and connecting pins on the docking end surface between two adjacent parts. Several workers push one part slowly close to the other part. Observe the positioning pins and holes, manually adjust the pose of the corresponding sections, and connect the sections after the posit...

AI Technical Summary

Problems solved by technology

The attitude adjustment assembly system can better solve the shortcomings of poor synchronization of operations in the docking of rocket sections, the inability to quantify the detection and adjustment of section attitudes, and the low degree of equipment integration; reduce the number of repeated trial assemblies and human factors in the assembly process. Assembly errors, etc., greatly improving the quality and accuracy of rocket segment docking
