Description
本發明有關於一種用於放電加工的電極治具，特別是一種將放電尖點設置在拉桿軸心(平行於Z軸)的電極治具，使得放電加工機帶動電極治具以拉桿的軸心進行轉動時，放電尖點依然會位在拉桿的軸心上，使得放電尖點不會改變X、Y、Z三軸方向的座標位置。 The present invention relates to an electrode jig for electric discharge machining, in particular to an electrode jig with the discharge tip set on the axis of the tie rod (parallel to the Z axis), so that the electric discharge machine drives the electrode jig to the axis of the tie rod. When rotating, the discharge cusp will still be located on the axis of the pull rod, so that the discharge cusp will not change the coordinate position of the X, Y, and Z axes.
傳統的物件加工技術因應不同的加工需求而有如：車床、銑床、磨床、鑽床、搪床等各種不同型式的金屬加工機，讓金屬加工機對被加工物進行切削，使得被加工物能達到預設的形狀大小，而隨著科技技術不斷地精進，被加工物的尺寸大小被要求到精密等級，導致傳統的物件加工技術已經無法符合現在的需求。 The traditional object processing technology is based on different processing needs, such as: lathes, milling machines, grinding machines, drilling machines, boring machines and other different types of metal processing machines. With the continuous improvement of science and technology, the size of the processed object is required to be at a precision level, resulting in the traditional object processing technology can no longer meet the current needs.
然而，放電加工法(Electro Discharge Machining，EDM)是一種目前常見的精密加工方法，其中，放電加工法是一種高能量密度的熱加工法，而放電加工法是利用放電加工機的電極與被加工物之間的介電流體產生放電作用，讓放電加工機對被加工物進行火花蝕刻，使被加工物透過火花蝕刻而產生的高溫來達到預設的形狀大小，進而被加工物的尺寸大小能達到精密的需求。 However, electric discharge machining (Electro Discharge Machining, EDM) is a common precision machining method at present. Among them, EDM is a high energy density thermal machining method, and EDM is to use the electrode of the electric discharge machine and the workpiece to be processed. The dielectric fluid between the objects produces a discharge effect, so that the electric discharge machine can perform spark etching on the workpiece, so that the workpiece can reach the preset shape and size through the high temperature generated by the spark etching, and then the size of the workpiece can be meet precise requirements.
請參閱圖1所示，為放電加工機常使用的習知電極治具10，其中，習知電極治具10主要由一拉桿11、一承載座體12以及一電極棒13所構成，拉桿11具有一組裝於放電加工機20的桿件111以及一能選擇組卸於拉桿11的鎖固件
112，桿件111的軸心設有一平行於Z軸的縱向軸線111a，而鎖固件112沿著縱向軸線111a而排列於桿件111，此外，承載座體12連接於鎖固件112，使得鎖固件112位在承載座體12與拉桿11之間，而電極棒13的局部區段連接於承載座體12以設為一固定部131，則電極棒13的剩餘區段設為一傾斜於固定部131的放電部132，如圖所示，放電部132於遠離固定部131的一端具有一放電尖點132a，而放電尖點132a橫向間隔排列於縱向軸線111a，使得放電尖點132a沒有設置在縱向軸線111a上。

於放電加工機20具體應用時，放電加工機20因應被加工物的尺寸大小而帶動習知電極治具10以縱向軸線111a為軸心進行轉動，讓電極棒13的放電尖點132a會繞著縱向軸線111a進行移動，使得放電尖點132a會改變橫軸(X軸與Y軸)方向的座標位置，其中，一旦放電尖點132a的橫軸方向座標位置被改變，放電加工機20就必須先花費時間計算放電尖點132a目前的座標位置，而後放電加工機20才能帶動習知電極治具10進行移動，讓放電尖點132a移動至加工位置，使得放電加工機20才能對被加工物進行放電加工，藉此，放電加工機20對被加工物進行放電加工的作業時間就會被拉長，相對無法提高產能。

請參閱圖3、圖4與圖5所示，電極棒34設有一呈現圓柱狀的固定部341以及一從固定部341延伸形成的放電部342，而放電部342於遠離固定部341的端部設為一放電尖點342a，其中，電極棒34從安裝洞324d的安裝入口324f穿入至安裝洞324d的內部，使得電極棒34以一傾斜於上述縱向軸線的***方向D穿入至安裝洞324d的內部，於此實施例中，***方向D垂直於電極連接部324的第一斜面324a，使得第一斜面324a的法線方向平行於***方向D，接下來，電極棒34的放電部342透過安裝洞324d的安裝出口324e而穿出於安裝洞324d的外部，進而放
電部342朝向校正規33的校正部333進行移動以讓放電部342的放電尖點342a能接觸於校正部333的校正面333a，當放電尖點342a接觸於的校正面333a時，放電尖點332a沿著於縱向軸線311a而排列於拉桿31的下方位置，而放電尖點342a還定位於桿件311的縱向軸線311a上，使得縱向軸線311a於重疊放電尖點342a的位置設為一固定點311b，同時，放電尖點342a沿著縱向軸線311a而縱向間隔排列於受測部325的受測面325b，使得放電尖點342a的高度位置不同於受測面325b，進而放電尖點342a與受測面325b之間的縱向距離保持在一固定長度L。

如圖所示，當放電部342的放電尖點342a能接觸於校正部333的校正面333a時，電極棒34傾斜於縱向軸線311，其中，電極棒34的固定部341位於承載座體32的安裝洞324d內部以連接於承載座體的電極連接部324，而電極棒34的放電部342位在安裝洞324d的外部，並且，整個放電部342位在縱向軸線311a與安裝洞324d之間。請參閱圖3與圖10所示，承載座體32的鎖固洞324g內部設有一定位栓35，而定位栓35鎖固於鎖固洞324g，並且，定位栓35的端面碰觸於電極棒34的固定部341，讓電極棒34連接於承載座體32的電極連接部324，進而因為定位栓35的端面碰觸於固定部341而防止固定部341脫離於安裝洞324d，然而，電極棒34透過定位栓35連接於電極連接部324僅方便說明之用，亦如圖11所示，承載座體32的電極連接部324還設有一連通於安裝洞324d的輔助鎖固洞324h，而鎖固洞324g與輔助鎖固洞324h兩者分別位在安裝洞324d的相對兩側，其中，輔助鎖固洞324h內部設有一平行於定位栓35的輔助定位栓36，而輔助定位栓36鎖固於輔助鎖固洞324h，並且，輔助定位栓36的端面碰觸於電極棒34的固定部341，讓固定部341同時被定位栓35與輔助定位栓36接觸以防止脫離於安裝洞324d。

請參閱圖12所示，於放電加工的電極治具30配合放電加工機40使用時，先將校正規33卸除於承載座體32的電極連接部324，接下來，拉桿31連接於放電加工機40，而放電加工機40因應被加工物的尺寸大小而帶動電極治具30以縱向軸線311a為軸心進行轉動，當電極治具30以縱向軸線311a進行轉動時，電極棒34的放電尖點342a依然會位在縱向軸線311a上，使得放電尖點342a於X、Y、Z三軸方向的座標位置不會因為轉動而被改變，進而當放電加工機40帶動電極治具30進行轉動之後，放電加工機40就能省去計算放電尖點342a目前座標位置的時間，而讓放電加工機40能直接帶動放電尖點342a移動至加工位置來對被加工物進行放電加工，致使能縮短放電加工機40對被加工物進行放電加工的作業時間。
Please refer to FIG. 12 , when the
請參閱圖13所示，放電加工機40長時間對被加工物進行放電加工會導致電極棒34磨損，進而需要將電極棒34更換為一替換電極棒37，當要將電極棒34更換為替換電極棒37時，先將定位栓35鬆脫於承載座體32的鎖固洞324g，使得定位栓35的端面沒有碰觸於電極棒34的固定部341，進而電極棒34能分離於承載座體32的安裝洞324d，接下來，將替換電極棒37從安裝洞324d的安裝入口324f穿入至安裝洞324d的內部，使得替換電極棒37的局部區段透過安裝洞324d的安裝出口324e而穿出於安裝洞324d的外部，進而替換電極棒37能朝向校正規33的校正部333進行移動以位在替換電極棒37端部的一替換放電尖點371能接觸於校正部333的校正面333a，當替換放電尖點371接觸於的校正面333a時，替換放電尖點371位在縱向軸線311a上以重疊於固定點311b，使得替換放電尖點371與受測面325b之間的縱向距離依然保持在固定長度L。
