Problems solved by technology

Although the above invention patent applications use laser technology to clean the surface of objects, it is difficult to clean special parts such as small or miniature metal cylindrical inner walls, because the cylindrical metal inner wall is difficult to operate and observe during the cleaning process. It has always been a difficult point in laser rust removal

Embodiment Construction

[0021] Such as figure 1 The shown laser derusting device comprises a laser controller 1, a laser 2, an acoustic sensor 11, a workbench controller 9, a workbench 8, a central controller 10 and a derusting head 12; the derusting head 12 is fixed on the light pipe 4, Its light outlet is perpendicular to the surface of the metal part 7 placed on the workbench 8, and a total reflection mirror 5 with a 45-degree angle is installed at the corner of the light guide 4; 13 Input the detection signal into the central controller 10; the central controller 10 is connected with the laser controller 1 and the workbench controller 9 through signal lines.

[0022] The working method of the laser descaling device is to put the metal piece 7 on the workbench 8, move the derusting head 12 to the position where the metal 7 to be derusted starts to be derusted, and adjust the distance between the derusting head 12 and the metal piece 7 , so that the output laser is focused on the surface of the me...

Abstract

The invention discloses a laser rust-removing device, which comprises a central controller, a laser, a working table controller, a working table, an acoustic sensor and a rust-removing head. The laser is guided into the cylindrical rust-removing head through a light guide pipe; a light outlet is vertical to the cylindrical metal inner wall; and the automatic control and precise positioning in the laser rust-removing process are realized by combining the acoustic sensor, the central controller and the working table. The laser rust-removing device solves the problem of removing rust on the cylindrical metal inner wall and other special surfaces.

Description

technical field [0001] The invention relates to a laser descaling device, in particular to a laser descaling device for special surfaces such as cylindrical metal inner walls. Background technique [0002] In metal production, engineering construction, shipbuilding and other industries closely related to the use of metal, effectively removing the metal rust layer has always been a difficult problem that everyone has paid attention to. Especially on some special surfaces such as the inner wall of steel pipes, it is more difficult to remove rust. However, in many engineering applications, these special surfaces are one of the key factors determining the service life of devices or equipment. Traditional derusting methods include mechanical derusting method, chemical derusting method, sand blasting derusting method, high-pressure water jet derusting method, etc. Because the chemical derusting method will cause damage to the metal and easily affect the environment, etc.; the hi...
