ザビーム用のカバー装置。 Two retractable screw covers are installed in the laser beam path between the fixed part and the movable part in a laser processing machine.
The two screw covers are installed in series, and both ends of one screw cover are fitted into the cylindrical part of the fixed part and the cylindrical part of the coupling member, and both ends of the other screw cover are fitted into the cylindrical part of the movable part and the cylindrical part of the coupling member. In the laser beam cover device, the coupling member is attached to a holder that is movable along a guide rail installed parallel to the direction of expansion and contraction of the screw cover, in which the two screw covers are wound around each other. 1. A cover device for a laser beam, characterized in that a coupling member is rotatably supported on a holder so as to be rotatable about an axis parallel to an expansion/contraction direction of a screw cover.
