  • Locking mechanisms in a laser nozzle holder
    Patent number: 11975407
    Abstract: A nozzle holder for a laser processing head of a laser processing system is provided. The nozzle holder includes a substantially cylindrical hollow body shaped to matingly engage a laser nozzle. The hollow body defines a longitudinal axis extending therethrough and a plurality of apertures dispersing around a circumference of the hollow body. The nozzle holder also includes a plurality of pawls configured to operably engage the laser nozzle within the hollow body by extending through the plurality of apertures of the hollow body. The nozzle holder further includes a sleeve substantially surrounding the hollow body and the plurality of pawls. The sleeve includes a pawl retractor that is movable along the longitudinal axis to physically displace the plurality of pawls axially and radially relative to the longitudinal axis for disengagement of the plurality of pawls from the laser nozzle.
