Abstract

The handheld laser welding device comprises a workpiece containing table, a positioning rotating mechanism, an angle adjusting mechanism and a handheld laser welding machine, the angle adjusting mechanism is fixed to the top of the positioning rotating mechanism, and the handheld laser welding machine is arranged on the side of the workpiece containing table. The handheld laser welding machine comprises a laser, a transmission optical fiber, a handheld welding head and a control system, the transmission optical fiber is connected with the laser and the handheld welding head, and the control system is used for controlling the working state of the laser; the positioning rotating mechanism comprises a connecting bottom plate, a rotating piece and a positioning piece, the connecting bottom plate is used for clamping a workpiece to be welded, the rotating piece comprises an outer ring and an inner ring which can rotate relatively, the outer ring is fixed to the connecting bottom plate, and the positioning piece is arranged on the inner ring and used for positioning a connector to be welded; the angle adjusting mechanism comprises a mounting bottom plate and a welding head mounting plate, the mounting bottom plate is fixed to the top of the inner ring, the handheld welding head is arranged on the welding head mounting plate, and the included angle between the welding head mounting plate and the horizontal plane is adjustable.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and in particular relates to a handheld laser welding device. Background technique [0002] The flexibility and cost-effectiveness of handheld laser welding are high. As a new type of welding equipment, handheld laser welding devices have developed rapidly in recent years. Usually, when a hand-held laser welding device is used to weld a circular joint, the welding head needs to be fixed first, and the rotating shaft drives the workpiece to rotate with the hand-held laser welding device to complete the welding work. However, the above-mentioned welding method cannot be used when the workpiece has a long base size and the workpiece is inconvenient to rotate. Because laser welding is sensitive to the focus position, the focus position needs to be kept stable during the welding process, and the bending radius of the optical fiber generally needs to be greater than 200mm; when the workpiece...
