New description: [New technical field] This creation is a technical field involved in electrical discharge machining, especially the electrode holder # for connecting electrodes. [Prior Art] The principle of electric discharge machining is basically a hot processing method that uses electric energy to convert into a workpiece and heats the workpiece. During electrical discharge machining, the transitional arc discharge phenomenon occurs in the gap between the electrode and the working pole in the liquid to generate heat effect on the workpiece. At the same time, the liquid in the process is subjected to vaporization explosion due to discharge pressure and heat, and the workpiece is melted at this time. The molten part is melted into the working fluid accompanying the liquid vaporization phenomenon, and the workpiece is caused to discharge by the action of the discharge. Thus, the desired shape can be processed, and the electric discharge machine (EDM) can be completed. Electrical Discharge Machine] is a machine tool that uses metal corrosion to destroy metal. The electric discharge machine is connected to the processing head with the electrodes, so that the electrode collet is provided at the end of the main shaft to connect the electric 35, and the workpiece is placed on the table having the opposite polarity to the electrode. . The electrode holder is generally as shown in the fifth figure; wherein the center side (10) of the electrode head (10) is provided with a center column (62), and the four end angles of the page side (10) opposite to the center column (62) Each unit forms a protruding extension column (63) 'Main (63) grinding and adding jade to form a top surface (631) of good horizontality so that the center column (62) of the electrode holder (6〇) protrudes into the clamp The clamping hole (70) of the seat (^) is transversely disposed with the bolt (72) for abutting against the central column (62) of the cooling hole (Π), and the bottom side of the clamping seat (7〇) corresponds to each of the protruding columns (μ), 3 M384076 is also provided with a face (73), and the face (73) is also ground to maintain a good level, and the contact with the stud (63) is flat without shaking. However, because the electrode is missing (6〇) The top side (61) is in close contact with the surface of the surface. If any of the top sides (6 i ) are worn or due to processing errors, it will be limited to the studs (63) and the electrode holder. (6〇) One-piece forming 'So the frontal surface (61) is poorly worn, the entire electrode holder (60) must be scrapped, and the entire electrode is discarded (6〇) for scrapping, The material cost is actually a lot of loss. [New content] In view of the above problems, the creator further studies and develops. Therefore, the main purpose of this creation is to provide an electrode chuck structure, which mainly changes the structure of the electrode chuck. The contact with the clamp seat is designed as a detachable and replaceable structure, so that the entire electrode chuck is not scrapped in part. In order to achieve the above purpose, the technical means used in this creation is to provide # The electrode chuck structure has a detachable positioning post at each of its end corners, wherein the positioning post includes two ends, one end is a control end, and the other end is a connection end, the manipulation The central portion of the top surface of the top surface is horizontally abutted; whereby the positioning post is damaged and can be individually disassembled and replaced. - the connecting end of the positioning post is externally threaded, and the top side of the electrode holder is provided with an internal thread corresponding to the clamping post. The keyhole' is screwed into the joint. ^ Therefore, according to the technical means of this creation, the brief description of the functions that can be obtained by this creation is as follows: Column, this main creation It is to change the electrode holder to contact against the holder. It is set to be independently disassembled and replaced. The connection at one end of the positioning post 4 M384076 end screw is combined with the locking hole of the electrode holder, the positive needle and the position post The top is provided with a grinding-and-welding area for the contact of the holder. The melon crime is caused by the wear of the positioning column or the damage of the positioning column. ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ 1′′ to loosen the connecting end of the positioning post as early as possible to make it out of the electrode holder, you can change the red, j谀 install another – new positioning column, so it is different from the conventionally formed blade electrode holder Master, this creation does not need scrapped electrode chucks to save unnecessary materials and bamboo long electrode chuck processing costs, providing a more consistent effect. In addition, this creation can use the same material for the position column. "Replace different materials, and you can select different material requirements according to the occasion to suit the purpose. [Embodiment] This creation is an electrode chuck structure. Please refer to the first figure. The basic shape of the electrode holder (ίο) of this creation is the same as the conventional structure, and has a top side (11); the characteristics of this creation are A detachable positioning post (20) is disposed at each of the four end corners of the top side (丨丨). Please refer to the first and second figures. The positioning post (2〇) of this creation contains two ends, one end is a polygonal column-shaped control end (21), and the other end is a male threaded connection ^&(22) 'The central area of the top surface of the control end (21) is a well-welded area with good precision (2 3 )' and the top side (丨丨) of the electrode holder (1 〇) is shown in the first and third figures. Corresponding to the positioning post (2〇) setting - the internal thread locking hole (24); whereby each positioning post (20) is screwed to the locking hole (24) by its connecting end (22), and the connecting end (22) is Fine-tune the height up and down along the keyhole (24) to ensure that the positioning posts (2〇) on the electrode holder (10) are at the same height as the contact area (23) and the control end of the positioning post (20) ( 21) is exposed on the top side (11) of the electrode holder (10). Thus, as shown in the first and second figures, the top side of the electrode holder (1 〇) (11) 5 M384076 is centered after the center column (12) is set. The electrode holder (10) is extended into the holder with the center column (12). The clamping hole (71) of the seat (70) is placed transversely with the bolt (72) against the outer side of the center column (12), and the abutting surface (73) of the bottom side of the clamping seat (10) is thus attached to the abutting area ( 23) Contact flatness is indeed the configuration of the electrode holder (1〇) and the holder (7〇). This feature is characterized in that one of the positioning posts (20) is longitudinally attached to the area (23) 'over-wearing' or one of the positioning posts (20) is damaged, as long as the loosening rotation • turn the positioning column (2〇) The control end (21) 'disconnects the connecting end (22) from the locking hole (24), and then replaces the new positioning post (20), re-threading the position of the locking hole (24) 'completely unnecessary As is conventional, it is necessary to scrap and discard the electrode holder (10). This creation is also shown in the fourth figure. The shape of the positioning post (2 〇) can be changed. The control end (21) of the clamp column (20) is a hexagonal column, but he can be the control end (31) set to four. The columnar positioning column (3〇), or the positioning column (40) of the cylindrical steering end (41), and the positioning column (2〇) (3〇) (4〇) can also be made of different materials, such as plasticity. Materials, or metal materials with better wear resistance, etc. Regardless of the shape of the positioning post (20) (30) (40), an abutment zone (3 3) (43) is formed on the top side. The above embodiments are merely illustrative of the techniques of the present invention and their effects, and are not intended to limit the present invention. Anyone who is familiar with the technology can modify or change the above embodiments without violating the technical principles and spirit of the creation. Therefore, the scope of protection of this creation should be as follows. Column. 6
