Method for removing paint layer on inner wall surface of cylindrical component

Abstract

The invention relates to a method for removing a paint layer on an inner wall surface of a cylindrical component. The method comprises the following steps that working parameters of a laser generatorare set, and the laser generator is driven to stretch into the cylindrical component by means of an actuating mechanism; the laser generator is controlled to output indication light, and a posture ofthe laser generator is adjusted, so that the indication light can be aligned with a preset cleaning starting point; and the actuating mechanism is started and the laser generator is driven to move, the laser generator is controlled to output laser, and laser scanning is performed on the paint layer on the inner wall surface of the cylindrical component to complete removal of the paint layer on theinner wall surface of the cylindrical component. The method can solve the problem that white paint is low in light absorptivity and thus difficult to remove, a coating on the inner wall surface is accurately removed, a process is simple and easy to operate, an environment cannot be polluted, meanwhile, automatic operation is convenient to achieve, only the coating on the inner wall surface of thecylindrical component is removed, a metal part of the cylindrical component cannot be damaged, an cleaning effect is good, and no coating is left.

Description

technical field [0001] The invention relates to the technical field of laser cleaning, in particular to a method for removing a paint layer on the inner wall surface of a cylindrical component. Background technique [0002] After World War II, all countries attached great importance to military development. Now, the missile launcher has become an indispensable military weapon for all countries. The barrel component is an important part of the tactical missile, which can be used for the storage, transportation and launch of certain military weapons. At present, most of the cylindrical components are high-temperature-resistant composite materials, which can be used many times. [0003] The paint layer on the surface of the cylindrical member is mostly white paint with a thickness of 0.4-1mm, which is drag-reducing, wear-resistant, high-temperature, high-humidity and corrosion-resistant, and it is difficult to remove it by conventional means. After being used for a period of...

Problems solved by technology

One of the cleaning methods commonly used in China is to use traditional manual grinding. This method is inefficient, time-consuming, low-precision, and is likely to cause potential material damage, etc., and has certain risks.

Another cleaning method is mechanical paint removal, which will cause mechanical damage; sandblasting paint removal has high requirements on the factory environment and will damage the surrounding devices
