Description

この発明は、照明を内部に取り付けたノズルに関し、その一例としてレーザ溶接装置の不活性ガスを噴射するノズル内に、光源を内蔵した照明付きノズルに関する。   The present invention relates to a nozzle having an illumination mounted therein, and as an example, relates to an illuminated nozzle having a light source built in a nozzle for injecting an inert gas of a laser welding apparatus.

従来から、溶接装置には、噴射ノズルから冷却媒体（オイルや水等）を噴出しながら冷却して溶接材を溶接しているものがあるが、溶接する部分が暗がりとなるため、溶接部分を明るく照らすためのライトを必要としている。従来の溶接装置の照明装置は、溶接トーチの近傍か、又は溶接トーチに添わせる状態で取り付けられ、溶接材の溶接部分を斜め方向や垂直方向から照明している。   Conventionally, there are welding apparatuses in which a welding medium is welded by cooling while jetting a cooling medium (oil, water, etc.) from an injection nozzle. I need a light to shine brightly. A conventional illumination device for a welding apparatus is attached in the vicinity of the welding torch or attached to the welding torch, and illuminates a welded portion of the welding material from an oblique direction or a vertical direction.

さらに、精密金属部品の溶接や小型や大型金型の修正、医療器具の溶接、センサーの溶接、シートメタル加工等の精密な溶接に用いられるレーザ溶接装置において、溶接面が酸化しないように不活性ガス（アルゴンガスやヘリウムガス、窒素ガス等）を溶接面にノズルから噴射しなら、このノズルとは別のフレキシブルなチューブの先端に設けたライトから溶接部分に光を照射しながら溶接作業を行っている。
特開２００５−１１１５５１号公報 特開２００３−３２６３６８号公報 Furthermore, in laser welding equipment used for precision welding, such as precision metal parts welding, small and large metal mold modifications, medical equipment welding, sensor welding, sheet metal processing, etc., it is inert so that the welding surface does not oxidize. If gas (argon gas, helium gas, nitrogen gas, etc.) is injected from the nozzle onto the welding surface, welding work is performed while irradiating the welding part with light from the light provided at the tip of a flexible tube different from this nozzle. ing.

しかし、前記従来の溶接装置の照明装置は、溶接作業に伴って冷却媒体の噴射ノズルと照明装置の両方を調節しなければならず、特に後者のレーザ溶接装置の場合は不活性ガスを噴射するフレキシブルなノズルとフレキシブルなチューブの照明装置とは全く別体であるので、ノズルから不活性ガスを溶接面に噴射する場合に、ノズルの先端が溶接面に向いているか否かを目視で確認しなければならない。しかも、溶接面の移動に伴って照明装置が必ずしも溶接面を的確に照射していないこともあるので、細密な溶接のために、照明装置のライトが溶接面に正確に照らすようにセットし直さなければならなかった。また、溶接に際してヒューム（煙）が発生して、その煤が照明装置に付着して時間とともに照明効率を低下させるという問題もあった。   However, the illumination device of the conventional welding apparatus must adjust both the cooling medium injection nozzle and the illumination device according to the welding operation, and in particular, in the case of the latter laser welding apparatus, the inert gas is injected. Since the flexible nozzle and the lighting device for the flexible tube are completely separate, when injecting inert gas from the nozzle onto the welding surface, visually check whether the tip of the nozzle faces the welding surface. There must be. Moreover, as the welding surface moves, the lighting device may not necessarily irradiate the welding surface accurately. For precise welding, the lighting device light must be set so that it accurately illuminates the welding surface. I had to. In addition, fumes (smoke) are generated during welding, and the soot adheres to the lighting device, and there is a problem that the lighting efficiency decreases with time.

この発明は、上記問題点を解決することを目的としてなされたものであり、溶接面を照明装置で照らせばそれと同時に、気体や液体等の流体が溶接面に的確に噴射される照明付きノズルを提供することを目的とする。   The present invention has been made for the purpose of solving the above-described problems. When a welding surface is illuminated with an illumination device, a lighted nozzle that accurately jets a fluid such as gas or liquid to the welding surface simultaneously. The purpose is to provide.

上記課題を解決するためこの発明の照明付きノズルは、フレキシブルチューブの先端に、ノズルが取り付けられ、このノズル内に光源を配置してノズルの先端から光が照射すると共に、チューブからの流体がノズルから噴射するよう構成した。 In order to solve the above-mentioned problems, the illuminated nozzle of the present invention has a nozzle attached to the tip of a flexible tube, and a light source is arranged in the nozzle to irradiate light from the tip of the nozzle. It was comprised so that it might inject from.

上記構成により、溶接面を照らすと流体が正確にその溶接面に向くことになり、照明される箇所と、流体が噴射される箇所がピッタリと一致する。さらに、光源はノズル内に配置されているので、ヒューム（煙）による煤で汚れない。また、流体が流れるノズル内に光源があるので、光源が高温になっても照明熱は上がらない。   With the above configuration, when the welding surface is illuminated, the fluid is accurately directed to the welding surface, and the illuminated location and the location where the fluid is ejected are exactly the same. Furthermore, since the light source is disposed in the nozzle, it is not fouled by fume (smoke). Further, since the light source is in the nozzle through which the fluid flows, the illumination heat does not increase even when the light source becomes high temperature.

また、本発明の照明付きノズルは、ノズルの内周面に、流体が通過する切れ込みが入れられていることを特徴とする。
さらに、本発明の照明付きノズルは、光源がフレキシブルチューブ内の先端部に位置し、この光源がノズルの細管の流路の端部に嵌まり込んでいることを特徴とする。 In addition, the illuminated nozzle of the present invention is characterized in that a slit through which fluid passes is formed on the inner peripheral surface of the nozzle.
Furthermore, the illuminated nozzle of the present invention is characterized in that the light source is located at the tip of the flexible tube, and the light source is fitted into the end of the flow path of the capillary tube of the nozzle.

本発明の照明付きノズルは、光源が照らす溶接面と、ノズルからの流体の噴射先とは一致するので、溶接面を照明すれば、流体は溶接面に正確に噴射され、流体の噴出するノズルの角度を調整する必要が無いので、溶接作業や修正作業が容易であり、非常に作業効率が向上する。また、光源はノズル内に配置されているので、ヒューム（煙）による煤の影響は全く受けない。   In the illuminated nozzle of the present invention, the welding surface illuminated by the light source matches the spray destination of the fluid from the nozzle. Therefore, if the welding surface is illuminated, the fluid is accurately ejected onto the welding surface and the fluid is ejected from the nozzle. Since there is no need to adjust the angle, welding work and correction work are easy, and work efficiency is greatly improved. Further, since the light source is disposed in the nozzle, it is not affected at all by the fume (smoke).

次に、本発明の実施の形態である照明付きノズルを詳細に説明する。
図１は、本実施の形態の照明付きノズルを装備したレーザ溶接装置の斜視図、図２は本発明の照明付きノズルの平面図、図３はノズルを分解した平面図、図４は図３の部分拡大図である。 Next, the illuminated nozzle according to the embodiment of the present invention will be described in detail.
1 is a perspective view of a laser welding apparatus equipped with an illuminated nozzle according to the present embodiment, FIG. 2 is a plan view of the illuminated nozzle of the present invention, FIG. 3 is an exploded plan view, and FIG. FIG.

この実施の形態の照明付きノズル１は、可撓性を有するフレキシブルチューブ３内に、アルゴンガス、ヘリウムガス、窒素ガス等の不活性ガスを流し、ノズル４の先端から不活性ガスを噴射して溶接面の酸化を防止しつつ溶接作業や修正作業を行なう照明付きノズル１の一例である。   The illuminated nozzle 1 of this embodiment is configured to flow an inert gas such as argon gas, helium gas, nitrogen gas or the like into a flexible tube 3 having flexibility and inject the inert gas from the tip of the nozzle 4. It is an example of the nozzle 1 with illumination which performs a welding operation | work and a correction operation | work, preventing the oxidation of a welding surface.

前記フレキシブルチューブ３は、円錐台状部分５の先端に略球状の連結部６が形成された合成樹脂製のパーツ７が多数連結されており、それぞれの連結部６を円錐台状部分５の後端に気密に嵌め込んで、パーツ同士を長く連結してフレキシブルチューブ３を構成している。本発明のフレキシブルチューブ３は必ずしもこのような円錐台状のパーツ７を連結したものに限定されず、可撓性を有するチューブであればその構成は問わない。   The flexible tube 3 has a plurality of synthetic resin parts 7 each having a substantially spherical connecting portion 6 formed at the tip of the truncated cone portion 5, and the connecting portions 6 are connected to the rear of the truncated cone portion 5. The flexible tube 3 is configured by fitting the ends in an airtight manner and connecting the parts long together. The flexible tube 3 of the present invention is not necessarily limited to the one in which such truncated cone-shaped parts 7 are connected, and the configuration thereof is not limited as long as it is a flexible tube.

この実施の形態の照明付きノズル１の先端部に、光源８としてＬＥＤ（発光ダイオード）が配置されている。ただし、光源８はＬＥＤに限定されるものでなく、通常の小型電球やレーザ光線、光ファイバー等であってもよく、その種類は問わない。このＬＥＤの光源８に電気を通電するための電線９がフレキシブルチューブ３内に配置されている。そして、フレキシブルチューブ３内の適当な箇所から外部に出て、電源に接続されている。なお、電線部分の孔１０からも不活性ガスが漏れないように、シール剤等で完全に塞いでいる。   An LED (light emitting diode) is disposed as the light source 8 at the tip of the illuminated nozzle 1 of this embodiment. However, the light source 8 is not limited to the LED, and may be a normal small light bulb, a laser beam, an optical fiber, or the like, and the kind thereof is not limited. An electric wire 9 for supplying electricity to the light source 8 of the LED is disposed in the flexible tube 3. And it comes out from the suitable location in the flexible tube 3, and is connected to the power supply. In addition, it is completely sealed with a sealant or the like so that the inert gas does not leak from the hole 10 in the electric wire portion.

フレキシブルチューブ３の先端には、ノズル４が気密に嵌め込まれている。このノズル４は金属製（例えば、真鍮で内面はクロムメッキを施す）であって、筒状の後端部１８が前記球状の連結部６に嵌め込まれている。ノズル４の先端部は細管１１であって不活性ガスが噴射できるように流路１２を備える。図５はノズル４の後端からノズル４内を見た状態を示したものであるが、円形の中央部がノズル４の細管１１の流路１２であり、その外周に花びら状に切れ込み１３が入れられており、不活性ガスが光源８のＬＥＤに邪魔されることなくこの切れ込み１３部分を通過してノズル４の先端から噴射できるように構成されている。   A nozzle 4 is fitted airtightly at the tip of the flexible tube 3. The nozzle 4 is made of metal (for example, brass and the inner surface is chrome-plated), and a cylindrical rear end portion 18 is fitted into the spherical connecting portion 6. The tip of the nozzle 4 is a thin tube 11 and is provided with a flow path 12 so that an inert gas can be injected. FIG. 5 shows a state in which the inside of the nozzle 4 is viewed from the rear end of the nozzle 4. The circular center portion is the flow path 12 of the thin tube 11 of the nozzle 4, and a petal-like cut 13 is formed on the outer periphery thereof. The inert gas can be injected from the tip of the nozzle 4 through the cut portion 13 without being obstructed by the LED of the light source 8.

図１は、前記照明付きノズル１をレーザ溶接装置２に取り付けた状態を示したものである。このレーザ溶接装置２はレーザヘッド１４を備え、レーザ光照射部１５は溶接作業のために適した位置にポジショニングすることが可能である。   FIG. 1 shows a state in which the illuminated nozzle 1 is attached to a laser welding apparatus 2. The laser welding apparatus 2 includes a laser head 14, and the laser beam irradiation unit 15 can be positioned at a position suitable for welding work.

次に、上記照明付きノズルの使用状態について説明する。
一般的には、このレーザ溶接装置２は、種々の細密な溶接や加工に使用できるが、特に金型などの修正作業に使用して従来の金型の製作に比べて大幅な時間短縮が図られている。作業に際しては、図示していないが、作業テーブル上にチャックを載置し、そのチャック上に金型等のワーク１６を固定する。そして、照明付きノズル１の光源８を点灯すると共に、不活性ガスをノズル４の先端から噴射しながら作業を行なう。図６は作業中の溶接面の拡大図である。 Next, the use state of the illuminated nozzle will be described.
In general, the laser welding apparatus 2 can be used for various fine welding and processing. However, the laser welding apparatus 2 can be used for repairing a mold or the like, and can greatly reduce the time compared to the conventional mold manufacturing. It has been. In the work, although not shown, a chuck is placed on a work table, and a work 16 such as a mold is fixed on the chuck. Then, the light source 8 of the illuminated nozzle 1 is turned on, and the work is performed while injecting an inert gas from the tip of the nozzle 4. FIG. 6 is an enlarged view of the welding surface in operation.

金型１６にレーザを当てながら、不具合な箇所を修正する。不活性ガスを高温となる溶接面に噴射しながら作業をすれば、金型表面の酸化を防止でき表面の荒れを防止できる。その際、顕微鏡１７を覗きながらの作業になるが、従来は不活性ガスを噴射するノズルと照明用のライトとは別体であったので、不活性ガスのノズルとライトは別々に溶接面に位置合わせをしなければならなかった。   While applying the laser to the mold 16, the defective part is corrected. If the operation is performed while injecting the inert gas onto the high-temperature welding surface, the mold surface can be prevented from being oxidized and the surface can be prevented from being rough. At that time, the work is performed while looking through the microscope 17. However, since the nozzle for injecting the inert gas and the light for illumination are conventionally separate, the nozzle and the light for the inert gas are separately provided on the welding surface. I had to align it.

本実施の形態の照明付きノズル１は、光源８が照らす先とノズル４からの不活性ガスの噴射先とが一致するので、溶接面を光源８で照らせばノズルは必ず溶接面に向いている。このため、照明の位置を合わせたり、不活性ガスの噴出する角度を目視で調整する必要が無いので、溶接作業や修正作業が容易となり、作業効率が向上する。   In the illuminated nozzle 1 according to the present embodiment, the tip illuminated by the light source 8 and the jet destination of the inert gas from the nozzle 4 coincide with each other. . For this reason, since it is not necessary to adjust the position of illumination or to visually adjust the angle at which the inert gas is ejected, welding work and correction work are facilitated, and work efficiency is improved.

さらに、光源８はノズル１内に配置されて不活性ガスが表面を流れているので、溶接作業により発生するヒューム（煙）による煤で汚れない。また、不活性ガスが流れるノズル４内に光源８があるので、高温となる光源８を用いても照明熱は上がらない。   Further, since the light source 8 is disposed in the nozzle 1 and the inert gas flows on the surface, the light source 8 is not fouled by fumes (smoke) generated by the welding operation. Further, since the light source 8 is provided in the nozzle 4 through which the inert gas flows, the illumination heat does not rise even when the light source 8 having a high temperature is used.

他の実施の形態
上記では、レーザ溶接装置２に本発明の照明付きノズル１を使用した例を説明したが、本発明は、ノズル４内に不活性ガスを流すものに限定されるものではなく、その他に、トーチ式の溶接装置において、オイルや水を冷却媒体とするノズルであっても適用できる。 Other Embodiments In the above, the example in which the illuminated nozzle 1 of the present invention is used in the laser welding apparatus 2 has been described. However, the present invention is not limited to the flow of an inert gas into the nozzle 4. In addition, in a torch type welding apparatus, even a nozzle using oil or water as a cooling medium can be applied.

即ち、フレキシブルチューブの先端のノズル内に、絶縁を施した光源（ＴＥＤ，ライト等）を内装して、不活性ガスの代わりに流体物である水やオイルをノズルから噴射できるようにすればよい。溶接面を冷却するために噴射する冷却媒体の噴射位置と光源からの光の照明位置が一致するので、作業効率が向上することは前記と同様である。   In other words, an insulated light source (TED, light, etc.) is provided in the nozzle at the tip of the flexible tube so that water or oil, which is a fluid, can be ejected from the nozzle instead of the inert gas. . Since the injection position of the cooling medium that is injected to cool the welding surface matches the illumination position of the light from the light source, the working efficiency is improved as described above.

なお、前記フレキシブルチューブ３は、円錐台状部分５の先端に略球状の連結部６が形成された合成樹脂製のパーツ７を多数連結したが、本発明のチューブ３はゴム製のホースに網組み線を被覆したようなものでもよい。   The flexible tube 3 has a large number of synthetic resin parts 7 each having a substantially spherical connecting portion 6 formed at the tip of the truncated cone portion 5, but the tube 3 of the present invention is connected to a rubber hose. It may be one that covers the braided wire.

また、前記フレキシブルチューブとして、針金の埋め込まれた合成ゴム製のチューブのようなものであってもよい。用途に応じて材質は選択すればよい。   The flexible tube may be a synthetic rubber tube embedded with a wire. What is necessary is just to select a material according to a use.
