LASER OPTIC HEAD Russian patent published in 2018 - IPC B23K26/14 B23K26/64 B23K26/70 

FIELD: physics.

SUBSTANCE: laser optic head comprises an outer fixed body (1) and an inner movable body (3) with a nozzle (4). The body (3) is moved by means of a rack (6) mounted on the inner movable body (3) and a pinion shaft (5) mounted on the mechanism bracket (16). The mechanism (16) is fixed to the outer fixed body (1) and is connected to an electric drive. In the lower part of the outer fixed body (1), a capacitive sensor (8) is installed to set and control the size between the nozzle cut and the workpiece (9). At the nozzle outlet, there is a removable nozzle (7) with a narrowing-expanding channel at the outlet. For modes of cutting, welding, punching the holes, a removable nozzle (7) is used, which has a diameter in a narrow section of 0.2±0.02 mm and an expansion angle of 30°. For the mode of cutting metal of 20 mm to 40 mm, a removable nozzle (7) is used which has a diameter in a narrow section of 0.5±0.02 mm and an expansion angle of 15°.

EFFECT: increased accuracy of processing, economy and versatility of the head.
