Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to an improved swing head mechanism. Background Art

[0002] The welding oscillating head is a device used to increase the width of a single weld during the welding process. It is mainly used for wider welds, such as groove welds and fillet welds. When the welding gun is wider, if the welding gun does not swing, the width of the single weld will be narrower, and defects such as high in the middle and low on both sides may occur. In order to solve this problem, the welding oscillating head can make the welding gun swing back and forth along the width of the weld during welding, so as to achieve the ideal weld shape and quality. Working principle of welding oscillating head The welding oscillating head usually consists of a mechanical oscillating mechanism and an electrical control system. The welding gun is installed on the slide of the welding oscillator, and the swing parameters are set and adjusted by the controller to control the swing of the welding gun. Due to changes in factors such as workpiece material, weld width, welding current, welding voltage, welding speed, etc., the speed during welding will also change. The welding oscillator needs to be able to adjust the swing width and swing speed, and some also need to adjust the dwell time at both ends.

[0003] During the laser welding process, the internal temperature of the welding swing head is too high, which will cause the focusing mirror and the lower protective lens inside the installation chamber to deform due to excessive temperature, affecting the welding work. At the same time, the parts inside the installation chamber will also be deformed due to excessive temperature, making it impossible to install the focusing mirror and the lower protective lens.
