Airplane paint fading and spraying motion platform based on macro-micro parallel mechanism

Abstract

The invention discloses an airplane paint fading and spraying motion platform based on a macro-micro parallel mechanism. The motion platform comprises four supporting stand columns, an upper portion platform supporting plate, a movable platform, a spraying gun, a first motion branched chain, a second motion branched chain, six steel cables, four visual sensors, a lower portion platform supporting plate and a controller. The airplane paint fading and spraying motion platform based on the macro-micro parallel mechanism has the following beneficial effects that the movable platform and the spraying gun are controlled by means of the first motion branched chain and the second motion branched chain which are in parallel, so that the spraying gun can achieve rotation in two degrees of freedom, namely pitching and yawing regardless of the pose of the platform, and the consistency and homogeneity of a paint spraying process are guaranteed; the profile of the surface of a fuselage is obtained through the visual sensors to guarantee that the spraying gun can perform automatic spraying at a fixed distance, and the cost can be lowered; and meanwhile, the spraying thicknesses of all paint vehicle layers are uniform, the time is accurate, and an oil paint air drying phenomenon caused by an excessively low speed and wet edges caused by an excessively high speed can be avoided.

Description

technical field [0001] The invention belongs to the technical field of civil aviation equipment, and in particular relates to a motion platform for paint removal and spraying of aircraft based on a macro-micro parallel mechanism. Background technique [0002] Under normal circumstances, an airliner needs to be painted and maintained every five years on average. Coupled with factors such as frequent mergers in the aviation industry, the repainting cycle of airliners is generally shorter. Moreover, it is necessary not only to ensure the quality of painting, but also to ensure the efficiency of painting, so as not to affect the normal operation of airlines. Therefore, higher requirements are put forward for airliner painting companies. At present, many institutions are working on shortening the painting cycle of the whole aircraft and the research on the parking time of aircraft painting. In 2013, a professional aircraft painting company in Dubai redesigned and painted the out...

AI Technical Summary

Problems solved by technology

[0003] At present, the global aircraft painting industry is mainly based on manual painting, and the painting work faces several major problems: ①The continuous working time of the whole machine painting is long, and the efficiency of manual painting is low

②The painting of a complete aircraft requires a team of 30 people with professional knowledge. The training cycle of the complete aircraft painting technology is usually 3-5 years, and the cost is huge

During the painting process, it is easy to have uneven paint on both sides of the fuselage, resulting in an imbalance of the aircraft

④ There is a fixed time limit for each layer of paint spraying, so it is difficult to grasp the painting time
