Description

本発明は細穴放電加工機に関する。   The present invention relates to a fine hole electric discharge machine.

燃料噴射ノズルの噴射口の形状において、噴射口の出口側の内径を入り口側の内径よりも大きくすることにより、噴射燃料の微粒化又は気化効率を良くすることが知られている（例えば、特許文献１）。   In the shape of the injection port of the fuel injection nozzle, it is known to improve the atomization or vaporization efficiency of the injected fuel by making the inner diameter of the outlet side of the injection port larger than the inner diameter of the inlet side (for example, patents) Reference 1).

燃料噴射ノズル１０１の噴射口の長さと口径は燃料噴射量や噴霧特性に大きな影響を及ぼす要因である。したがって、燃料噴射ノズル１０１の噴射口の加工には、ドリル加工よりも高精度な加工ができる細穴放電加工機が多く用いられている。   The length and diameter of the injection port of the fuel injection nozzle 101 are factors that greatly affect the fuel injection amount and the spray characteristics. Therefore, a thin hole electric discharge machine that can perform machining with higher accuracy than drilling is often used for machining the injection port of the fuel injection nozzle 101.

図９は、φｄ１の大口径噴射口１０６の加工を別の細穴放電加工機（図示省略）で行った後に、内径がφｄ２の小口径噴射口１０５の加工を第２の細穴放電加工機２０４で行うという第２の加工方法の説明図である。   In FIG. 9, after processing the large-diameter injection port 106 of φd1 by another thin hole electric discharge machine (not shown), the small-diameter injection port 105 having an inner diameter of φd2 is processed by the second small hole electric discharge machine. It is explanatory drawing of the 2nd processing method performed by 204. FIG.

第２の細穴放電加工機２０４は、従来の細穴放電加工機（図示省略）に、前記ターンテーブル装置２２７に装着された前記燃料噴射ノズル１０１の先端部を撮影可能なＣＣＤカメラ２２９を設けたものであり、燃料噴射ノズル１０１の先端部を撮影して、被加工物である燃料噴射ノズル１０１の取り付け姿勢を検出して取り付け角度の補正を可能にしたものである。   The second fine hole electric discharge machine 204 is provided with a CCD camera 229 capable of photographing the tip of the fuel injection nozzle 101 mounted on the turntable device 227 in a conventional fine hole electric discharge machine (not shown).

しかしながら、細穴放電加工機２０１によって燃料噴射ノズル１０１を加工する場合、加工ヘッド２１７に設けた電極ホルダ２１９に対して、大口径噴射口１０６加工用の電極と小口径噴射口１０５加工用の電極の着脱交換が必要であり、１工程のサイクル時間が長くなるという問題がある。   However, when the fuel injection nozzle 101 is processed by the narrow hole electric discharge machine 201, the electrode for processing the large-diameter injection port 106 and the electrode for processing the small-diameter injection port 105 are compared with the electrode holder 219 provided in the processing head 217. Therefore, there is a problem that the cycle time of one process becomes long.

前記被加工物を細穴放電加工機２０１で加工する場合、１サイクルが１８５秒であり、その内訳は、加工時間が１２０秒、電極と電極ガイドの交換が６０秒、被加工物の交換が５秒であった。   When the workpiece is machined by the fine hole electric discharge machine 201, one cycle is 185 seconds, and the breakdown is that the machining time is 120 seconds, the electrode and the electrode guide are exchanged for 60 seconds, and the workpiece is exchanged. 5 seconds.

第２の加工方法の場合は、２台の細穴放電加工機への被加工物の着脱を行う必要があり、また、被加工物をＣＣＤカメラで撮影して取り付け角度を補正する必要あり、第１の加工方法と同様に１工程のサイクル時間が長くなるという問題がある。   In the case of the second machining method, it is necessary to attach / detach the workpiece to / from the two small hole electric discharge machines, and it is necessary to shoot the workpiece with a CCD camera to correct the mounting angle, Similar to the first processing method, there is a problem that the cycle time of one process becomes long.

上述の第２の加工方法の場合の１サイクルは１５５秒であり、その内訳は、加工時間が１２０秒、カメラによる取り付け角度補正２５秒、加工物の交換（２回）１０秒であった。   In the case of the second machining method described above, one cycle was 155 seconds, which consisted of a machining time of 120 seconds, a camera mounting angle correction of 25 seconds, and a workpiece exchange (twice) of 10 seconds.

本発明は上述の如き問題を解決するために成されたものであり、本発明の課題は、大口径部と小口径部からなる多数の噴射口を有する燃料噴射ノズルの如き被加工物の加工においても、電極の着脱交換が不必要であって１工程のサイクル時間が短かく、かつ、一台の機械で加工できる細穴放電加工機を提供することである。   The present invention has been made to solve the above-described problems, and an object of the present invention is to process a workpiece such as a fuel injection nozzle having a large number of injection ports including a large-diameter portion and a small-diameter portion. However, it is necessary to provide a small hole electric discharge machine that does not require electrode replacement and replacement, has a short cycle time for one process, and can be processed by a single machine.

上述の課題を解決する手段として請求項１に記載の細穴放電加工機は、Ｚ軸に平行な軸心を回転中心とするＡ軸と、該Ａ軸に直交する軸心を回転中心とするＢ軸とを有する被加工物固定載置用のターンテーブルを備えた細穴放電加工機において、棒状電極の下端部をガイドする電極ガイドをＷ軸方向に昇降位置決め自在に設けた第１Ｗ軸キャリッジと第２Ｗ軸キャリッジとを一体的にＸ軸方向とＹ軸方向とへ移動位置決め自在に設け、前記第１Ｗ軸キャリッジに前記棒状電極を前記ターンテーブル上の被加工物に対して昇降位置決め自在の第１加工ヘッドを設けると共に、前記第２Ｗ軸キャリッジに前記ターンテーブル上の被加工物に対して昇降位置決め自在の第２加工ヘッドを設け設けたことを特徴とするものである。   As a means for solving the above-mentioned problem, the thin hole electric discharge machine according to claim 1 has an A axis centering on an axis parallel to the Z axis and an axis orthogonal to the A axis as a center of rotation. A first W-axis carriage provided with an electrode guide for guiding a lower end portion of a rod-like electrode so as to be movable up and down in the W-axis direction in a thin hole electric discharge machine having a turntable for placing and fixing a workpiece having a B-axis And the second W-axis carriage are integrally provided so as to be movable and positionable in the X-axis direction and the Y-axis direction, and the rod-shaped electrode can be vertically positioned with respect to the workpiece on the turntable on the first W-axis carriage. A first machining head is provided, and a second machining head is provided on the second W-axis carriage so as to be movable up and down with respect to the workpiece on the turntable.

請求項２に記載の細穴放電加工機は、請求項１に記載の細穴放電加工機において、前記棒状電極に加工液を供給する加工液供給手段と棒状電極回転駆動手段とを前記第１および第２加工ヘッドのそれぞれに設けたことを特徴とするものである。   The fine hole electric discharge machine according to claim 2 is the fine hole electric discharge machine according to claim 1, wherein a machining liquid supply means for supplying a machining liquid to the rod-shaped electrode and a rod-shaped electrode rotation driving means are arranged in the first shape. And the second machining head.

本発明によれば、同軸で穴径が異なる段付き穴加工の場合でも、一台の細穴放電加工機で電極交換を行わずに加工ができるので高精度の加工が可能となり、かつまた被加工物の着脱が１回で加工が完了するので加工時間を大幅に短縮することができる。   According to the present invention, even in the case of stepped hole machining with coaxial and different hole diameters, machining can be performed without replacing the electrodes with a single fine hole electric discharge machine, so that high-precision machining is possible, and moreover, Since the processing is completed in one attachment / detachment of the workpiece, the processing time can be greatly shortened.

また、一台の細穴放電加工機で製品加工が完了するので、中間加工製品のストックが不要となるため無駄な搬送行程が不要となり生産能率が向上する。さらに、複数の細穴放電加工機を使用する必要がないので省スペースとなる。これにより、結果的に加工製品の原価低減に寄与することができる。   In addition, since product processing is completed with a single small-hole electric discharge machine, the stock of intermediate processed products is not required, so unnecessary transport steps are not required, and the production efficiency is improved. Furthermore, since it is not necessary to use a plurality of fine hole electric discharge machines, space is saved. Thereby, it can contribute to the cost reduction of a processed product as a result.
