PURPOSE:To make an additional shaft device for a laser robot compact by jointly using hollow guide bars of an emitting head for both moving/guiding means and an asist gas supply pipeline. CONSTITUTION:In the additional shaft device, adjusting/moving means (Ma, 70, 72) for bringing a laser emitting head 50 into focus at the point to be irradiated with laser beam in the direction of a prescribed axial line are provided and also guiding motion is stabilized by forming a guiding means for guiding the movement of the emitting head 50 by the vertical structure of plural hollow guiding bars 30. The hollow guiding bars 30 are jointly used for both the moving/guiding means for the laser emitting head 50 and the asist gas supply pipeline. In this way, the additional shaft device for laser robot can be made compact. |
