Welding device with air purification function

Abstract

The invention relates to a welding device with an air purification function. The device comprises a workbench, a control box and a laser device, wherein the control box is arranged above the workbenchand fixedly connected with the workbench, the laser device is arranged at the bottom of the control box, an execution system is arranged in the control box, and a purification mechanism and an auxiliary mechanism are arranged at the bottom of the control box; the auxiliary mechanism comprises a fixed pipe, a rotating pipe, a rotating ring, a first bearing, a driving assembly and two auxiliary assemblies; each auxiliary assembly comprises a cleaning rod, a sliding block, a supporting rod, a spring and two fixed blocks; and the purification mechanism comprises a fixed bevel gear and two purification assemblies. According to the welding device with the air purification function, the function of removing impurities on a workpiece is achieved through the auxiliary mechanism, so that the welding effect is prevented from being affected by the impurities; and in addition, the air purification function is achieved through the purification mechanism.

Description

technical field [0001] The invention relates to the field of welding, in particular to a welding device with an air cleaning function. 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 heat conduction, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through heat 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 applied in the precision welding of micro and small parts. [0003] Existing laser welding machines will produce ...

AI Technical Summary

Problems solved by technology

[0003] Existing laser welding machines will produce a large amount of welding fume during use. There are high concentrations of particulate matter in the welding fume. Long-term inhalation is prone to welder's pneumoconiosis. Not only that, when there are impurities on the workpiece, it will affect the laser on the workpiece. focus, thus affecting the welding effect
