3D Laser head optical axis distance adjustment device of metal 3D printer

摘要

In the present invention, the optical axis distance of the laser beam irradiated from the laser head, that is, the size of the laser beam irradiated to the focus point of the object to be processed can be adjusted simply and quickly without cumbersome or inconvenience. The optical axis distance adjusting device may include a barrel member provided to be elevating from the nozzle body of the nozzle unit so that the optical axis distance adjustment of the laser beam can be easily performed without change; And it provides a laser head optical axis distance adjusting device of a metal 3D printer comprising a; and an adjustment fixing unit provided to fix the elevation of the barrel member provided to be elevating in the nozzle body after adjusting the elevation. Accordingly, the optical axis distance of the laser beam can be quickly adjusted according to the processing conditions of the object to be processed, so that the processing can be performed quickly within a short time, and the effect of maximizing the operational efficiency resulting therefrom.
