Laser welding device for high-strength steel structure assembly

Abstract

The laser welding device comprises a laser welding device body, a collecting box is arranged on the lower right side of the laser welding device body, a connecting rod is fixedly installed at the upper end of the collecting box, the upper side of the connecting rod is slidably connected with a supporting plate in a penetrating mode, the left end of the supporting plate is fixedly connected with the laser welding device body, and the connecting rod is sleeved with a first spring; the upper end and the lower end of the first spring are fixedly connected with the supporting plate and the collecting box correspondingly, a cleaning roller is rotationally connected to the upper side of the right end of the collecting box, the lower end of the cleaning roller and the lower end of the collecting box are located on the same horizontal line, a scraping plate is arranged on the lower left side of the cleaning roller, the right end of the scraping plate is attached to the cleaning roller, and a magnetic rotating plate is arranged on the lower side of the scraping plate. The collecting box is arranged to collect impurities scraped off by the scraper conveniently, the impurities are prevented from falling on the surface of the steel structure again, the telescopic rod and the second spring are arranged to enable the right end of the scraper to be attached to the surface of the cleaning roller conveniently, and the scraping quality of the scraper is ensured.

Description

technical field [0001] The invention relates to the technical field of laser welding devices, in particular to a laser welding device for high-strength steel structure components. Background technique [0002] Laser welding is a method of welding using the heat generated by bombarding the weldment with a focused laser beam as the energy source. Due to the optical properties of laser such as refraction and focusing, laser welding is very suitable for welding of micro parts and parts with poor accessibility. Laser welding also has the characteristics of low heat input, small welding deformation, and is not affected by electromagnetic fields. Laser welding is one of the important aspects of the application of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is heat conduction, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the i...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem in the prior art that a large amount of impurities are easy to drop on the surface of the steel structure to be welded. If it is directly welded, it will have a certain impact on the welding quality of the steel structure. Laser welding device for high-strength steel structural components
