Description

TECHNICAL FIELD

[0001] The utility model relates to handheld laser welding machine technical field, concretely is a handheld laser welding machine. BACKGROUND

[0002] In the modern industrial manufacturing and processing field, laser welding technology has been very widely applied because of its high precision, high efficiency, low deformation and many other advantages. As an important member of laser welding equipment, handheld laser welding machine provides convenience for many small welding operations and local welding of complex structural parts, and is favored by the majority of production enterprises.

[0003] There are some problems to be solved in the use scene of the traditional handheld laser welding machine, for example, during the work gap, the operator can only place the handheld laser welding machine randomly around the workbench. Since the gun head part is usually equipped with a wire feeding mechanism, its structure is relatively delicate and has high precision requirements. Such random placement can easily cause the wire feeding mechanism to deform due to external force compression, collision and other factors. Once the wire feeding mechanism deforms, the wire feeding stability and uniformity in the subsequent welding process will be seriously affected, thereby reducing the welding quality, and even may frequently cause welding failure, increasing maintenance cost and downtime.

[0004] Therefore, we propose a handheld laser welding machine to solve the problems mentioned above. UTILITY MODEL CONTENTS
