2. Description of the Related Art Recently, laser processing devices that use laser beams for welding, cutting, drilling, trimming, and the like are increasingly being used. In such processing devices, lenses are mainly used to focus the laser beam. Lenses with different characteristics such as focal length are selected and used depending on the processing purpose. Furthermore, since the lens may be contaminated or damaged by spatter, fume, etc. generated from the workpiece during laser processing, it is often necessary to inspect the lens surface. Therefore, it is necessary to attach and detach the lens from the processing head quite frequently, but in the past, the work of attaching and detaching the lens of this type of laser processing equipment was often difficult, as can be seen from the structure of the conventional processing head shown in Fig. 3. It had the disadvantage of requiring time and effort.

策とはなり得ていない。 To address these problems, Japanese Patent Application Laid-open No. 58-112685
In this issue, as shown in Fig. 4, a plurality of processing heads consisting of a lens 1, a lens holder 2, and a processing nozzle 5 whose positions have been adjusted are provided movably with respect to a laser beam protection tube 3, so that lenses can be processed quickly. It makes exchange possible. However, the number of lenses that can be prepared using this method is not very large, and lens inspection requires the same effort and time as before, so it is not a sufficient solution. .

The problem to be solved by the present invention is that in a laser processing machine that uses a laser beam, the work of attaching and detaching the condenser lens, which is often necessary for inspection and replacement, requires a lot of time and effort, including position adjustment after installation. The problem is that it is time consuming and troublesome.

The present invention provides a processing head for facilitating the work of attaching and detaching the lens, which comprises:
The gist of this is that in a laser processing head that uses a condensing lens, there is a lens insertion port that allows the lens with a primary holder to be attached and removed from the side, and a position-defining port that allows the lens to be positioned. A storage holder having a guide and a holding mechanism for ensuring the fixation of the lens with the primary holder is fixed between the protection tube for the laser beam incident on the lens and the adjustment mechanism of the processing nozzle. It is located in a processing head for a laser processing machine.

FIG. 1 shows the configuration of a laser processing head according to the present invention. As shown in FIG. 1, the lens can be attached or removed without disconnecting the connection between the storage holder 6 and the protection tube 3 or the connection between the storage holder 6 and the position adjustment mechanism 4 of the processing nozzle 5, using the lens insertion port provided on the side of the storage holder. It takes place through 7.

FIG. 2 is a diagram showing a specific example of a lens with a primary holder and a storage holder of a laser processing head according to the present invention. The lens 1 is prepared by being attached to the primary holder 2. Therefore, all replacement lenses are also provided with a primary holder 2 of the same size. Reference numeral 8 denotes a guide for defining the position of the primary holder 2 within the storage holder 6, and it fits into a recess 8' provided inside the storage holder 6. 9 is a handle for attaching and detaching the primary holder to the storage holder. After inserting the lens 1 with the primary holder 2 into the storage holder 6 and aligning it, attach the primary holder holder 10 using a thumbscrew or the like.
The primary holder 2 is fixed by. Reference numeral 11 denotes an O-ring for the packing that is preset inside the storage holder 6, and is used to connect the primary holder 2 and the storage holder 6.
Prevent assist gas, etc. from leaking from the connection with the Reference numeral 12 denotes an elastic sealing material that prevents assist gas and the like from leaking from the connection between the storage holder 6 and the position adjustment mechanism 4.

なえる。 Adjustment of the position of the processing nozzle after the lens is attached can also be achieved by slight fine adjustment by the position adjustment mechanism 4, since the position of the lens within the storage holder 6 is almost reproduced by the guides 7 and 8. If you want to take out the lens, you can easily do so by simply loosening the primary holder presser 10 and holding the handle 9 of the primary holder 2.
