告されている（特開昭６１−１４９４号公報）。When cutting a workpiece using a laser beam machine, the processing head may collide with the workpiece, causing damage to the processing head. Ninthly, a technique has been reported that prevents damage by detecting the dimensions of a machining head relative to a workpiece using a sensor or the like (Japanese Unexamined Patent Publication No. 1494/1983).

ることのできるレーザ加工機の加工へラドに屑する。However, conventional laser processing machines only prevent the processing head from colliding with the workpiece and being damaged by detecting the dimension formed between the tip of the processing head and the workpiece as described above. No countermeasures have been taken against damage caused by the machining head moving laterally and colliding with the protrusion 1c of the workpiece or the like.゛The present invention has been made to solve the above-mentioned problems, and it provides a laser that can minimize damage to the processing head even if the processing head moves laterally and collides with some protrusion. A large amount of waste is generated by the processing machine.

FIG. 2 is a cross-sectional view in the axial direction of the processing head showing the operation of processing a workpiece by the processing head of the laser beam machine. Processing head (
1), a laser beam (2) from a laser processing machine oscillator (not shown) is guided and emitted along the axis of the processing head (1). The processing head (1) includes a cylinder (3) and a nozzle (4) attached to the lower end of the nuclear cylinder (3), and a condenser lens (6) is installed slightly above the joint between these two. ing. Of course, the condensing lens (5) condenses the halo laser beam (2) and converts the laser beam (2) into a high-energy laser beam into the workpiece (6).
)K to carry out predetermined processing, and its optical axis is aligned with the axis of the processing head (1).

) is formed, and if the nozzle (4) moves laterally and collides with a protrusion (6a) like fc shown in the figure, the stress at that time will be concentrated in the groove (4a). ing. Further, a hole (4b) is formed slightly above the groove (4), and assist gas is introduced from a pipe (not shown) connected to the hole (4b).

。However, as mentioned above, the processing head (1)
When the nozzle (4) collides with the nozzle (4a), the impact force is concentrated on the # (4a) and sometimes the nozzle (4) breaks through the groove (4a). At this time, the laser processing machine stops, but since the nozzle (4) is made to break easily, the transmission of collision force to the laser processing machine is relaxed, preventing damage such as distortion of the optical system of the laser processing machine. This can be prevented.
折ｍ後ｒｃ、ノズル（４）のみを安価に取替えることが
できメンテナンス上有利である。After folding, only the rc and nozzle (4) can be replaced at low cost, which is advantageous in terms of maintenance.
