Inside-beam powder feeding laser cladding device

Abstract

The invention relates to an inside-beam powder feeding laser cladding device, and belongs to the field of laser processing. The inside-beam powder feeding laser cladding device comprises a laser headassembly, wherein the laser head assembly comprises a supporting seat and a nozzle, the supporting seat is provided with a spectroscope, two reflection focusing mirrors, and a fine adjustment device used for fixing and adjusting the inclination angle of each reflection focusing mirror, the spectroscope receives an incident light beam and reflects the incident light beam to form a reflective lightbeam, and the two reflection focusing mirrors receive the reflective light beam and convert the reflective light beam into two focused light beams with different focuses correspondingly. According tothe inside-beam powder feeding laser cladding device, the reflective light beam is received by the reflection focusing mirrors, and the reflective light beam is converted into the two focused light beams with different focuses by the reflection focusing mirrors, the two focused light beams with different focuses are used for carrying out surface treatment and laser cladding on a matrix correspondingly; and stepless adjustment is carried out on the inclination angles of the reflection focusing mirrors through the fine adjustment device, so that the rapid positioning of light spots in the advancing, retreating, cleaning and repairing processes of a carrier is realized, and the processing efficiency is improved.

Description

technical field [0001] The invention relates to a laser cladding device for internal optical powder feeding, which belongs to the field of laser processing. Background technique [0002] my country's railway operation is high-speed and heavy-duty, and rail damage is becoming more and more serious. In the traditional repair process of worn rail surface, there are problems such as low work efficiency, large waste of resources, harsh working environment, insufficient impact toughness of welding repair layer, and difficulty in guaranteeing repair quality. The laser online repair technology can well make up for the above problems, not only can reduce costs, shorten the construction period, and improve efficiency, but also the traditional process can hardly match the repair quality. [0003] Laser repair is a process of cleaning + repair. Before processing the substrate, the surface of the substrate needs to be treated to ensure the processing quality of laser cladding.

Problems solved by technology

[0002] my country's railway operation is high-speed and heavy-loaded, and rail damage is becoming more and more serious. In the traditional repair process of worn rail surface, there are problems such as low work efficiency, large waste of resources, harsh working environment, insufficient impact toughness of welding repair layer, and difficulty in guaranteeing repair quality.

The laser online repair technology can make up for the above problems very well, not only can reduce costs, shorten the construction period, and improve efficiency, but also the traditional process is difficult to match in terms of repair quality.

[0003] Laser repair is a process of cleaning + repair. Before processing the substrate, the surface of the substrate needs to be treated to ensure the processing quality of laser cladding. The current laser cladding equipment can only achieve a certain function. The substrate Surface treatment requires the use of other equipment, and the substrate often needs to be positioned multiple times during processing, which affects processing efficiency
