Description
The present invention relates to a laser processing apparatus head formed in a laser processing apparatus and irradiating a laser beam, and more particularly, to a laser processing apparatus head having a structure in which separation, disassembly, and coupling are easy and the inside is kept clean will be.
Various machine tools are used to machine the base metal. The base material can be processed by using various kinds of machine tools such as a lathe, a milling machine, and a drilling machine, and one or more machine tools can be used to manufacture more various and suitable products. As a machine tool, not only a contact-type machining apparatus for processing a cutting edge or the like in contact with a base material, but also a non-contact type machining apparatus for irradiating and processing a high-temperature laser beam onto a base material are widely used.
The laser processing apparatus is configured to generate laser light, focus the laser light, and irradiate the laser light toward the processed surface of the base material. The laser machining apparatus has a smooth machined surface, no noise during operation, and can be finely and precisely machined, which is very useful in industrial fields. A head having an optical nozzle is formed at a portion of the laser processing apparatus facing the base material, and an optical system including a plurality of lenses is provided inside the head. Therefore, the focused laser beam can be irradiated from the optical system to the base material through the nozzle.
However, when particulate foreign substances having a small particle size or a small diameter penetrate into the inside of the head of such a laser processing apparatus, the optical system may be damaged and the normal operation of the apparatus may become difficult. Particularly, it is very difficult to shield the fine dust (fume) generated by evaporating instantaneously from the machined surface by the high-temperature laser beam while shielding the machined surface by spraying argon gas or compressed air at the time of processing the base material there is a problem.
Therefore, at least a part of the head must be separated or disassembled to clean the inside of the head from time to time. However, since the structure is difficult to separate, disassemble or reattach the head in the conventional case, maintenance and repair work can not be smoothly performed . In addition, there is a problem that fine dust or the like introduced into the inside of the head is adhered to the surface of the lens to damage the lens, or scatter the irradiated laser light, thereby significantly reducing the efficiency of the apparatus.
The technical problem to be solved by the present invention is to provide a laser processing apparatus head having a structure in which separation, disassembly, and coupling are easy and the inside is kept clean.
The technical task of the present invention is not limited to the above-mentioned tasks, and other technical subjects not mentioned can be clearly understood by those skilled in the art from the following description.
