Laser welding equipment and using method thereof

Abstract

The invention discloses laser welding equipment, and relates to the technical field of welding. The laser welding equipment comprises a workbench, a first vertical plate, a first supporting plate and a first motor, a first screw rod is fixedly connected to the output end of the first motor, a first moving plate is connected to the outer wall of the first screw rod in a threaded mode, and a laser welding gun is arranged at the bottom of the first moving plate; a second supporting plate is arranged on the surface of the workbench, a first air cylinder is installed on the surface of the second supporting plate, a concave plate is fixedly connected to the output end of the first air cylinder, a first clamping plate and a second clamping plate are fixedly connected to the surface of the concave plate, and a first fixing plate and a second fixing plate are fixedly connected to the surface of the second supporting plate; and the first air cylinder is started to enable the first clamping plate and the second clamping plate to make contact with the other two sides of a workpiece, all faces of the workpiece can be conveniently clamped, the phenomenon that the welding quality is affected due to loosening in the welding process is avoided, the first motor is started to drive the laser welding gun to move, and therefore the workpiece can be conveniently welded.

Description

technical field [0001] The present invention relates to the field of welding technology, and more specifically, relates to a laser welding device and its usage method. 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. It is mainly used for welding thin-walled materials and low-speed welding. The welding process is of heat conduction type, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the interior through heat conduction. By controlling the laser pulse Parameters such as the width, energy, peak power and repetition frequency of the workpiece are melted to 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 welding d...

Problems solved by technology

[0003] Existing welding devices often need to use fixtures to clamp the workpiece during the welding process, but the existing fixtures have complex structures and are inconvenient to use. At the same time, most of them are manually operated throughout the process, which reduces the welding efficiency and also affects the welding quality. At the same time, it increases the risk of welding process and reduces the safety performance of welding.
