Claims

[Scope of utility model registration request]

Two hollow arms through which the laser beam passes are interconnected in a flexible manner within the same plane by a hollow hinge in which each hollow hinge member connected to the end of each arm is rotatably connected by a hinge bin. , and a mirror that reflects a laser beam sent from one of the arms to the other arm is disposed inside the hollow hinge and is supported by the hinge bin, and a hinge pin of the hollow hinge is disposed inside the hollow hinge. a first gear relatively rotatably supported by a hinge pin; and a second gear meshed with the first gear and relatively rotatably supported by a fixed shaft fixed to one of the hinge members. The planetary gear mechanism is composed of a third gear integrally provided with the second gear, and a fourth gear fixed to the hinge pin and meshed with the third gear, and has a reduction ratio of 1/2. attached, and
A joint device for a laser processing machine, wherein a worm shaft rotatably supported by the other hinge member is engaged with the first gear of the planetary gear mechanism.
