Abstract

PURPOSE:To provide a working machine which can set always exactly and easily a focal length by enabling the adjustment of the relative vertical position of a ring which is connected to a lifting plate on the main unit of the working machine, holds the lifting plate and contacts rollingly with a work and a laser torch. CONSTITUTION:A work W fixed on a table 3 by a clamp 5 is set in such a way that the work can be moved as required by a moving device 4. A lifting plate 18 of which the driving force is decreased by a balancing weight 24 is lowered from a position 18' to 18. A case 12 fixed thereto and a fixing part 28 are both lowered. The bottom end of a torch 2 connected to the case 12 and a ring 31 connected via an adjusting device consisting of the part 28, shaft, body 30 are also lowered. The spherical bodies at the bottom ends of the stoppers 33 on the bottom surface thereof stop by contacting rollingly with the work W. The spacing between the bottom end of the spherical bodies and the bottom end of the torch 2 facing the work W penetrating through the central part of the ring 31 is freely adjustable by operating the knob 32 of the above-described adjusting device.
