Abstract:
1. A laser machining head comprising: an electrically conductive sensor part; a laser machining nozzle, said laser machining nozzle being integrated with said sensor part; an electrically conductive mount configured to hold said sensor part; an outer insulation part disposed around said mount, said outer insulation part being made of electrically insulating material, and said outer insulation part at least partially enclosing said mount; a metallic inner insulation part disposed within said outer insulation part, said inner insulation part forming a radiation shield, said inner insulation part being at least partially enclosed by said outer insulation part, said inner insulation part having the form of a sleeve, and said inner insulation part being electrically insulated from all other electrically conductive parts of the laser machining head; a fixed mechanical connection between said inner insulation part and said outer insulation part; a portion of said outer insulation part enclosing said inner insulation part, said portion of said outer insulation part having a cylindrical outer surface; an effective electrical insulation configured to electrically isolate said metallic inner insulation part from electrical communication with said electrically conductive sensor part, said electrical insulation disposed between said inner insulation part and said electrically conductive sensor part; a laser machining head upper part; a modular body detachably connected to said laser machining head upper part; said modular body including said outer insulation part, said metallic inner insulation part, and said mount; and, said modular body having an insulation section between said laser machining head upper part and said mount, said insulation section including said outer insulation part and said metallic inner insulation part.
