Description of the invention: [Technical field of the invention] The present invention relates to the technical field of electrical discharge machining, in particular to a fixture plate and an electrode holder for obtaining a program processing origin, and the positioning method thereof is more excellent. Precision. [Prior Art] The basic principle of electric discharge machining is a thermal processing method that uses electrical energy to convert into heat of a workpiece to rapidly melt the workpiece. During the electrical discharge machining, the machining fluid generates a transient arc discharge phenomenon in the gap between the electrode and the working pole, which in turn generates a heat effect on the workpiece, and at the same time, the liquid undergoes a gasification explosion due to the discharge pressure and heat, and the workpiece is melted at this time. In part, the phenomenon of liquid vaporization is slid into the machining fluid, and the workpiece is caused by the discharge to produce a discharge mark. Thus, the desired shape can be processed, and the electric discharge machine (EDM). Electrical Discharge L] is a machine tool that uses metal erosion to destroy metal. Nowadays, in order to improve production automation, it is necessary to process several workpieces at the same time. 7 'Requires setting; t each processing origin'.

Although the pre-existing case is arranged on the jig plate, the electrode holder has the advantage of convenient calculation design and processing origin. , ", However, in practice, the accuracy is achieved because the front electrode of the cited case corresponds to a positioning groove with a cross-shaped profile of ~ ° and ten, and the area of the "slot and rail" of the fixture plate is positioned concave. The tolerance between the slot and the positioning convex is very small. It is often "accurate, so the groove and the condition are different from each other." The electrode holder needs to be repeatedly placed in other positions of the fixture plate, and the screw is moved to move the electrode.

SUMMARY OF THE INVENTION The present inventors have made research and development in view of the above-mentioned § < screaming', and therefore the main object of the present invention is to provide a recording and processing fixture for recording, which is mainly based on a relatively simple technical method. You have made the electrode holder and the fixture board a high-precision, low-profile (1) 1549 wear configuration. The technical means used in the present invention are: an electric discharge machining fixture comprising an electrode fixture plate and a plurality of electrode holders disposed on the electrode fixture plate, wherein: the electrode treatment a surface having a surface opposite to the surface of the groove, and a groove having a groove shape is formed on the surface, and a guide surface of the small groove is formed on the inner side of the groove, that is, two directions of the groove The spacing of the guiding faces is gradually increasing along the vertical south;
β亥電極座為方形立體座狀，於面向該電極治具板該表 面之該面，延伸四對定位腳，該四對定位腳呈十字分配， 兩對在同一水平線上’另外兩對是在垂直線上，每一對定 位腳由兩凸腳組成，該兩&腳外側的距離恰可容許進入配 位槽内，而該凸腳每相應接觸該導向面呈斜弧面。 因此依據本發明的技術手⑨，本發明㈣的功能效益 特點簡要說明如下所列： 本么明主要係在相對電極治具板為小的電極座 上，形成突出的定位腳，利用定位腳面積小，以及定位腳 中的凸腳具斜弧面’因此具有些許金屬撓性，冑以凸腳的 斜弧面一經碰觸配位槽内側的導向面時，一方面藉斜弧面 與導向面接觸面小，另一方面利用凸腳的金屬撓性而有彈 性移動，因此這種彈性配合的手段得以抵消配位槽與定位 腳本身加工的誤差度，確保定位腳與配位槽形成接觸但不 會過度磨損’得以長久性地保持良好配合精度，以確保電 極座結合於電極治具板的加工原點位置精準自然保障電 1331549 極自動化加工產品之精準性。 2、本發明在電極治具板形成大面積的配位槽，狭小 的定位腳形成於小塊體的電極座，所以加工較能簡單容易 地達成良好精度。此乃大面積的電極治具板加工尺寸大的 配位槽，加工精度較易掌握，同理，電極座體積小，所以 各對定位腳形成的距離短’戶斤以要保持彼此的垂直度較容 易掌控，因此製造較以往更為簡單。The β-hai electrode holder has a square-shaped seat shape, and on the surface facing the surface of the electrode fixture board, four pairs of positioning legs are extended, the four pairs of positioning feet are distributed by the cross, and the two pairs are on the same horizontal line. On the vertical line, each pair of positioning legs is composed of two convex legs, and the distance between the outer sides of the two & feet is allowed to enter into the matching groove, and the convex legs are inclined to each other with the guiding surface. Therefore, according to the technical hand 9 of the present invention, the functional benefit characteristics of the invention (4) are briefly described as follows: The main reason is that the opposite electrode fixture plate is a small electrode holder, and a protruding positioning leg is formed, and the positioning foot area is utilized. Small, and the convex foot in the positioning foot has a beveled surface, so it has a certain degree of metal flexibility. When the inclined arc surface of the convex foot touches the guiding surface on the inner side of the matching groove, the inclined surface and the guiding surface are used on the one hand. The contact surface is small, and on the other hand, the metal of the protruding foot is elastic and elastically moved. Therefore, the elastic matching means can offset the error of the processing of the positioning groove and the positioning script body, and ensure that the positioning leg forms contact with the positioning groove but It will not be excessively worn out, and it will be able to maintain good matching precision for a long time, so as to ensure the precise position of the electrode holder combined with the processing origin of the electrode fixture board to ensure the accuracy of the 1331549 extremely automated processing products. 2. The present invention forms a large-area coordination groove in the electrode fixture plate, and the narrow positioning leg is formed on the electrode holder of the small block, so that the processing can be easily and easily achieved with good precision. This is a large-area electrode fixture plate processing large size of the coordination groove, the processing accuracy is easier to grasp, the same reason, the electrode holder is small, so the distance formed by each pair of positioning feet is short, to keep each other's verticality It's easier to control, so manufacturing is easier than ever.

The taper is formed by the two opposite guide faces (ΐ2ι) of each of the coordinate grooves (12) being gradually increased along the vertical height. The electrode holder (20) is a square-shaped seat for arranging on the electrode 1331549 • plate (10), wherein the electrode holder (20) faces the surface (u) of the electrode fixture plate (1) The face is extended by four pairs of positioning feet (21), the four pairs of positioning feet (21) are distributed by the cross, the two pairs are on the same horizontal line, the other two pairs are on the vertical line, and each pair of positioning feet (21) is made up of two convex The foot (22) is composed, and the distance between the outer sides of the two convex legs (22) is allowed to enter the matching groove (12). The respective convex legs (22) are long rails, facing the surface of the electrode fixture plate (10.). (11) is a free end, and each of the convex legs (22), as shown in the second figure, has a small arc-shaped oblique curved surface (221) corresponding to the guiding surface (121), due to the formed oblique curved surface ( 221), so the root (222) of the protruding leg (22) and the body is thicker than the oblique arc surface (221), and the corresponding electrode hole (14) of the electrode holder (2) is internally threaded.
