Intelligent laser welding machine based on numerical control technology

Abstract

The invention discloses an intelligent laser welding machine based on a numerical control technology, and relates to the field of intelligent laser welding machines, the intelligent laser welding machine comprises a laser welding machine body, and the laser welding machine body is provided with a protective cover for protecting the outside of the laser welding machine; the guiding feeding and discharging assembly can allow the to-be-welded metal piece to automatically enter the protection cover for laser welding of the laser welding machine, the metal piece is automatically discharged after welding is completed, the continuity of laser welding and feeding and discharging is guaranteed, the metal piece is located in the protection cover during welding, and the welding efficiency is improved. Metal chippings and harmful gas generated by welding cannot diffuse to the outside of the protective cover to form pollution, a collecting groove used for collecting the metal chippings generated in the process of laser welding of the to-be-welded metal piece is further formed in the bottom of the welding cavity, and the harmful gas is sucked in the metal chipping collecting process in a concentrated mode. And harmful gas is intensively sucked and then is secondarily filtered to be conveyed into the welding cavity again.

Description

technical field [0001] The invention relates to the field of intelligent laser welding machines, in particular to an intelligent laser welding machine based on numerical control technology. Background technique [0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. 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 of thermal conduction type, that is, the surface of the workpiece is heated by laser radiation, and the surface heat diffuses to the interior through thermal conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse and other parameters to melt the workpiece and form a specific molten pool. Due to its unique advantages, it has been successfully used in the precision welding of micro a...
