必要となるという欠点がある。[Problems to be solved] The processing nozzles of conventional laser processing machines are effective only for complete cutting, and in order to spray auxiliary gas during grooving and counterbore processing, the processing nozzle is effective only when cutting the machining piece in the laser emission direction. Processing powder and generated gas are blown away, and furthermore, these substances adhere to areas other than the processing area, causing problems in terms of finish. The disadvantage is that in some cases a post-processing step is required to remove them.

A set of two gas nozzles sandwiching a nozzle is used, and during laser processing, the gas nozzle located on the processing direction side that matches the processing direction is used for blowing auxiliary gas, and the other gas nozzle is located on the opposite side to the processing direction. The present invention provides a processing nozzle for a laser processing machine that uses a gas nozzle for suctioning auxiliary gas.
［実施例］
以下１本発明の実施例について図面を参照して説明する
。[Example] An example of the present invention will be described below with reference to the drawings.

図中１はレーザノズルで、集光照射するレーザ光３が通
過するに十分な大きさとされている。In the figure, reference numeral 1 denotes a laser nozzle, which is large enough for a focused laser beam 3 to pass through.

補助ガス吸引の両機能を兼備した複数個のガスノズル２
１〜２８が放射状に設けられている。Around this laser nozzle l, there are a plurality of gas nozzles 2 that have both the functions of blowing auxiliary gas and suctioning auxiliary gas.
1 to 28 are provided radially.
これらガスノズル２１〜２８は、レーザノズルｌをはさ

補助ガス吸引用となし得るようにしている。These gas nozzles 21 to 28 are two gas nozzles 21 and 22.23 and 24.25 that sandwich the laser nozzle l.
and 26, 27 and 28 are set as a pair, and during laser processing, a set of gas nozzles that coincide with the processing direction (for example, direction A in FIG. 2), for example, a gas nozzle located on the side of the 23 is used for blowing auxiliary gas, and the other gas nozzle 24 located on the opposite side to the processing direction can be used for sucking auxiliary gas.
次に作用を説明する。Next, the action will be explained.
まず、加工用レーザ発振器からのレーザ光３は集光レン
ズ４を透過し、レーザノズルｌを通過した後、加工対象
物９へ集光照射される。First, the laser beam 3 from the processing laser oscillator is transmitted through the condensing lens 4, passes through the laser nozzle l, and is then condensed and irradiated onto the workpiece 9.
今、溝入れ、ざぐり加工方向が矢印Ａ方向であった場合
、加工飛散物はレーザ光３よりも加工方向と反対方向に
吹き飛ぶ傾向にあるので、ガスノズル２３から吹き付け

飛散物を一緒に吸引する。尚、５．７は吹き出し機兼吸
引機で、この場合５は吹き出し機、７は吸引機として機
能する。Now, if the direction of grooving and counterboring is in the direction of arrow A, the machining debris tends to be blown away in the direction opposite to the machining direction rather than the laser beam 3, so the gas is blown from the gas nozzle 23 and the gas nozzle on the opposite side is Gas and flying debris are sucked together from 24. In addition, 5.7 is a blowing machine and a suction machine, and in this case, 5 functions as a blowing machine and 7 functions as a suction machine.

して作用させることを最大の特徴とする。Furthermore, when the processing direction is reversed, the roles of the blower/suction machines 5 and 7 can be changed. In order to have this function in any direction within the machining surface, the gas nozzles 21 to 28 for blowing and suction are divided around the laser nozzle l, and any pair of gas nozzles 21 to 28 can be activated by a machining direction signal. The main feature is that it can function as a spray nozzle or a suction nozzle.

A plurality of gas nozzles for both blowing auxiliary gas and suctioning auxiliary gas are provided in a radial manner, and a set of two gas nozzles sandwiching the laser nozzle is used to increase the applied F during laser processing.
A processing nozzle of a laser processing machine in which the gas nozzle located on the processing direction side of the set of gas nozzles coincides with the direction and is used for blowing auxiliary gas, and the other gas nozzle located on the opposite side to the processing direction is used for suctioning auxiliary gas. Because of that,
Not only during complete cutting, but also during grooving and counterbore processing, it is possible to prevent the work piece, processing powder, and generated gas from being blown away in the laser emission direction, and from adhering to areas other than the machined area.
This has the effect that post-processing can also be made unnecessary.
