  • Focusing head of a laser beam provided with a focusing lens for a machine for working metal and non-metal parts
    Patent number: 5837965
    Abstract: A focusing head of a laser beam provided with a focusing lens for a machine for working parts comprises an extractable lens-holding frame that supports the focusing lens, a supporting and centering bracket wherein the lens-holding frame is mounted in a disengageable manner, a spring in engagement with the supporting and centering bracket to urge the lens-holding frame in abutment against a stop socket. In that way the lens-holding frame is disengageable from the supporting and centering bracket by an action of compression of the spring and it can be extracted and reassembled in the focusing head without modifying centering and positioning of the focal spot of the lens.
