Coating device for aircraft fuselage surface machining

Abstract

The invention discloses a coating device for aircraft fuselage surface machining, and belongs to the technical field of spraying equipment. The coating device comprises a transverse moving mechanism, a vertical lifting mechanism and an adjustable equidistant spraying mechanism, wherein the transverse moving mechanism is slidably connected into two U-shaped plates, base plates are welded to the two ends of the two U-shaped plates together, a paint liquid box is installed on the transverse moving mechanism, a spraying pump is installed on the paint liquid box, and an input port of the spraying pump is communicated with the bottom of the paint liquid box through a liquid pumping pipe; the vertical lifting mechanism is fixedly connected to the transverse moving mechanism and is driven by the transverse moving mechanism to move transversely; and the adjustable equidistant spraying mechanism is fixedly connected to the top of the vertical lifting mechanism and is driven by the vertical lifting mechanism to form longitudinal lifting action. The problem that the coating thickness is inconsistent due to manual spraying is solved, the device can adapt to aircraft fuselages with various curved surfaces in different shapes, the adjustability is high, the spraying limitation is smaller, automatic spraying operation is achieved, the spraying efficiency is high, and the using effect is better.

Description

technical field [0001] The invention belongs to the technical field of spraying equipment, and in particular relates to a coating device for aircraft fuselage surface processing. Background technique [0002] Aircraft refers to a power plant with one or more engines to generate forward thrust or pull, and the fixed wings of the fuselage to generate lift. Aircraft that are heavier than air and fly in the atmosphere. Aircraft can be divided into military aircraft and aircraft according to their purposes. There are two types of civil aircraft. Military aircraft refers to aircraft used in various military fields, while civil aircraft generally refers to aircraft for all non-military purposes, such as passenger aircraft, cargo aircraft, agricultural aircraft, sports aircraft, ambulance aircraft, and experimental research aircraft.

AI Technical Summary

Problems solved by technology

[0003] At present, after the aircraft is produced, it needs to spray the fuselage, but the existing spraying method is generally manually spraying with a hand-held spray gun, because manual spraying will cause the distance between the spray gun and the aircraft fuselage to be uncontrollable, resulting in poor quality of spraying. The coating thickness is inconsistent, and when spraying equipment is used for spraying operations, because the outer wall of the aircraft fuselage is a curved surface, the problem of inconsistent coating thickness will also occur during spraying, and the efficiency of manual spraying is low, and the aircraft fuselage is relatively high. Need to use auxiliary equipment to complete the spraying operation, spraying is inconvenient, a large amount of harmful gas will be generated during spraying, and it will also affect the health of the staff
