Nozzle presetter for laser machining tool of laser beam machine

摘要

The invention provides a nozzle presetter for laser machining tool of laser beam machine for externally making position adjustments of nozzles for laser machining tools mounted on a laser beam machine.;A nozzle presetter 900 has a base 910, and a support portion 912 is mounted on an upper part of the base 910 to removably support a laser machining tool 60. An alternative beam source 920 is mounted at the center position in an upper part of the support portion 912. A target member 930 is removably mounted on a nozzle mounting member 660 of the laser machining tool 60 via mounting means 654. The target member 930 has a photoreceptor 940 mounted just under a center hole 932. The photoreceptor. 940 senses the quantity of light reaching the photoreceptor through the center hole 932 of the target member 930. The operator changes the axial position of the nozzle mounting member 660 using four adjustment screws 670. When a collected beam passes through the center hole 932 of the target member 930, output voltage of the photoreceptor 940 rises. When the operator is notified to that effect, he/she completes the adjustment.
