Abstract

PURPOSE:To directly lead a working gas up to a work point and to improve a responding speed together with a light-weighing by providing the floating nozzle which can move in the vertical direction for a work on the tip of a work nozzle. CONSTITUTION:A floating nozzle 6 is fitted by engaging with the opening part of a nozzle main body 1 slidably up and down to a work nozzle 1 in order to directly lead a working gas to the work point of a work 2 and projected to the external part. While under working by a laser beam machine the tip of the floating nozzle 6 is always brought into contact with the work 2 and can follow up even for the abrupt unevenness of the work. The working gas under working can be led to the work point with good efficiency and the workability can be improved. Since the floating nozzle 6 can slide lightly up and down for the nozzle 1 the manoeuverability in the vertical direction to the work is improved as well.

In addition to guiding the beam toward the workpiece 2, it also serves as an optical path for the processing laser beam. The processing nozzle l performs processing at a certain distance from the workpiece in order to avoid collision with the workpiece 2 or to optically measure the distance between the workpiece and the tip of the nozzle.

題かあった。(The problem that the invention aims to solve) In the processing nozzle of the laser processing machine as described above, the distance from the object to be processed (workpiece) is large, and it is necessary to consider the nozzle shape with sufficient consideration for the flow of processing gas. In addition, when moving the nozzle vertically to the workpiece, the most common method was to move it using an fttt structure that included the laser lens system and cooling system. There was a problem with equality.

It is possible to directly guide the processing gas to the processing point, is light in weight, has improved response speed, and has the advantage of reducing the processing point force). The purpose of the present invention is to obtain a nozzle that has less influence on the outside by blocking emitted light from the nozzle. A floating nozzle is provided at the tip of the nozzle that can move perpendicularly to the workpiece. [Operation] The floating nozzle in this invention comes into contact with the workpiece during processing and is pushed up, so that the workpiece is not affected by the processing nozzle force. )
At a distance, the floating nozzle moves towards the workpiece under gas pressure, thus always guiding the gas directly to the processing point.

元の影響を少なくする。Also, by blocking the light emitted by the workpiece being processed, the original influence on the outside is reduced.

In FIG. 2, 4 is a lens system for focusing the processing laser beam, 5 is a cooling system for cooling the lens thread 4, and a processing nozzle 1 for guiding the processing gas to the workpiece 2.
Connected to the il. 6 is a floating nozzle that is fitted into the nozzle 1 so as to be slidable up and down and protrudes to the outside to guide the processing gas directly to the processing point of the workpiece; its upper end portion 6a engages with the opening of the nozzle body 1; It is fitted together.

に導くことができ、従ってガスの消費も少なくできる。Next, the operation will be explained. During processing with the laser processing machine, the tip of the floating nozzle 6 is always in contact with the workpiece 2,
It can also follow sudden irregularities on the workpiece. Note that relatively gentle unevenness can be handled by controlling the axis of the processing machine main body. Due to these effects, processing gas during processing can be efficiently guided to the processing point, and gas consumption can therefore be reduced.

への影響も軽減できる。In addition, since the floating nozzle covers the processing point, it blocks the intense light generated during processing, which protects the human body and has no effect on devices that use light to measure the position between the processing machine and the workpiece. It can be reduced.

いるシステムへの影響も少なくなる。As described above, according to the present invention, since the floating nozzle is provided at the tip of the processing nozzle, gas can be guided directly to the processing point, thereby improving workability. Since the floating nozzle is light, it can improve the movement in the direction perpendicular to the workpiece, and the nozzle can also block the light emitted from the workpiece during processing, so it does not affect the system that optically measures the nozzle gap etc. It becomes less.
