Abstract
This utility model discloses a rapid off-axis laser-assisted focusing device for laser additive manufacturing, including a unit box, a connecting shaft disposed at the bottom of the unit box, and a welding head disposed at the bottom of the connecting shaft; a connecting assembly including a movable arm and a connecting ring disposed on one side of the movable arm; and an adjusting assembly including a rotating shaft and a movable plate in contact with the outer wall of the rotating shaft. By rotating the handle to align the reference line with the corresponding scale line, the movable arm and the laser-assisted focusing device can be rotated to the corresponding angle, and the laser-assisted focusing device can then emit a secondary laser with a specific defocus amount. When adjusting the main laser emitted from the welding head, it is only necessary to ensure that the focal point of the main laser coincides with the focal point of the secondary laser to quickly and accurately ensure that the main laser is maintained at the specified defocus amount.
