Abstract

The invention relates to a putty applying mechanism, comprising: a mounting seat; a displacement adjusting device, wherein the displacement adjusting device is arranged on the mounting seat; a fixing bracket, the fixing bracket is arranged at the output end of the displacement adjusting device; and a first telescopic driving element, The first telescopic drive element is arranged on the fixed bracket, and the output end of the first telescopic drive element is provided with a piston; the storage bucket is arranged on the fixed bracket, and the piston is slidably arranged on the storage bucket. In the material barrel, the material storage barrel is filled with putty; the elastic coating scraper is set on a fixed bracket, the interior of the coating scraper is a hollow structure, and the coating scraper and the storage barrel are far away from each other. One end of the piston is connected; a limiting frame, the limiting frame is sleeved outside the scraping plate, and a discharge chute is formed between the limiting frame and the scraping plate; at least one universal ball, the universal ball and the scraping plate Set on the same side of the fixed bracket. The invention is applied to the field of painting technology.

Description

technical field [0001] The invention relates to the technical field of smearing, in particular to a putty smearing mechanism. Background technique [0002] At present, there are process defects such as shrinkage holes and pinholes on the surface of composite material components such as aircraft wings, tail panels, radomes, and propellers after molding, which seriously affects the spraying quality. It is necessary to apply a layer of putty filling layer before grinding to fill the shrinkage cavity. Defects such as holes and pinholes. After the putty is dry and hardened, the surface is smoothed with sandpaper, and then painted to ensure the quality of the painting. In theory, the putty layer is required to be polished off before painting, only the putty inside the shrinkage cavity and pinhole is retained, and the base layer of the original material is not damaged. At present, the putty layer at home and abroad is generally applied by hand. When applying, there are problems s...
