Airplane surface paint stripping and grinding device based on pressure intensity control

Abstract

The invention discloses an airplane surface paint stripping and grinding device based on pressure intensity control and relates to the technical field of grinding equipment. The airplane surface paintstripping and grinding device based on pressure intensity control comprises a grinding unit, a telescopic limiting unit, at least three thin-film switches and a curved surface adaptation unit, wherein the grinding unit comprises a rotating assembly arranged in a lower shell, a ball spline shaft coaxially assembled with the rotating assembly and a grinding assembly at the lowest end; the driving end of the telescopic limiting assembly is coaxially assembled with the upper end of the ball spline shaft; the at least three thin-film switches are arranged at the grinding end of the grinding assembly; and the curved surface adaptation unit comprises a curved surface adaptation assembly movably connected with the lower shell and a guide assembly connected fixedly. According to the technical scheme of the airplane surface paint stripping and grinding device based on pressure intensity control, disclosed by the invention, the thin-film switches are mounted on a grinding head, and the effectivecontact area is measured in real time; and through combination with cylinder pressure, the pressure intensity of the grinding surface is controlled. The airplane surface paint stripping and grindingdevice based on pressure intensity control has the advantages of being controllable in pressure intensity of the grinding surface, wide in application range, good in grinding effect, simple in structure and low in cost.

Description

technical field [0001] The disclosure of the present invention relates to the technical field of grinding equipment, in particular to a pressure control-based aircraft surface paint stripping and grinding device. Background technique [0002] As an important process in aircraft overhaul, the paint stripping of aircraft skin is still mostly manually polished. Manual grinding is time-consuming, labor-intensive, inefficient, poor in consistency, and a large amount of dust is harmful to human health. The development of economical and efficient skin grinding equipment can improve the grinding accuracy and the consistency of the grinding effect for the grinding itself, and make the surface roughness of the ground surface lower after grinding; for the workers, it can reduce labor intensity and improve Improve the working environment and shorten maintenance man-hours; for maintenance companies, it can shorten the aircraft parking time, improve the mechanization degree and economic ...

AI Technical Summary

Problems solved by technology

[0003] Because the surface of the aircraft is mostly a curved surface, the shape changes greatly, and the grinding accuracy is relatively high. Once the grinding is excessive, the entire skin of the aircraft may be damaged. Therefore, it is difficult and demanding to design an automatic paint removal and grinding equipment for the aircraft skin.
