Abstract

1. Оптическая лазерная головка, содержащая наружное и внутреннее газовые сопла с каналами для подвода активного и защитного газов, установленные концентрично и с зазором, фокусирующую линзу, размещенную во внутреннем сопле, и сквозные отверстия, выполненные на боковой поверхности внутреннего сопла, отличающаяся тем, что внутреннее сопло выполнено по типу сопла Лаваля, а фокусирующая линза размещена во внутреннем сопле с обеспечением базирования своей цилиндрической поверхностью по цилиндрической поверхности внутреннего сопла с возможностью перемещения вдоль оси, при этом канал для подвода активного газа к внутреннему соплу расположен между фокусирующей линзой и соплом Лаваля, а сквозные отверстия во внутреннем сопле расположены над линзой.2. Оптическая лазерная головка по п. 1, отличающаяся тем, что она снабжена фиксаторами с возможностью ограничения движения фокусирующей линзы вдоль оси, расположенными ниже сквозных отверстий и выше нижнего канала подвода технологического газа.1. An optical laser head comprising an outer and inner gas nozzle with channels for supplying active and protective gases, mounted concentrically and with a gap, a focusing lens placed in the inner nozzle, and through holes made on the side surface of the inner nozzle, characterized in that the inner nozzle is made like a Laval nozzle, and the focusing lens is placed in the inner nozzle with the provision of basing its cylindrical surface on the cylindrical surface of the inner nozzle with while moving along the axis, the channel for supplying active gas to the inner nozzle is located between the focusing lens and the Laval nozzle, and through holes in the inner nozzle are located above the lens. 2. The optical laser head according to claim 1, characterized in that it is equipped with clamps with the possibility of restricting the movement of the focusing lens along the axis, located below the through holes and above the lower channel for supplying process gas.
