Description
Technical Field
[0001] This utility model belongs to the field of mold clamping technology, and specifically relates to a practical electrode clamp. Background Technology
[0002] CNC milling machines, also known as Computer Numerical Control (CNC) milling machines, are a type of CNC machine tool with powerful machining capabilities. As mechanical products become increasingly precise and complex, and demands are frequently changing, especially for mechanical parts required in fields such as aerospace, shipbuilding, and military, which have high precision requirements, complex shapes, and small batch sizes, CNC milling machines are widely used.
[0003] An electrical discharge machine (EDM) is a machining tool primarily used for electrical discharge machining. It is widely used in the manufacture of various metal molds and mechanical equipment. It is a special machining method that utilizes the electro-erosion effect generated by pulsed discharge between two electrodes immersed in a working fluid to remove conductive materials; it is also known as electrical discharge machining or electro-erosion machining.
[0004] CNC milling machines are limited by tool interference and material hardness. Although EDM machines have a slow processing speed, they can overcome the hardness limitations. Some electrode products still need to be processed by EDM machines after being processed on CNC milling machines. However, existing electrode clamps have many defects, such as inaccurate positioning, inconvenient installation, and inability to be clamped on both types of equipment at the same time, which affects production efficiency.
[0005] Therefore, there is an urgent need for an electrode fixture that can be mounted on both a CNC milling machine and a discharge machine. Utility Model Content
[0006] To address the problems existing in the prior art, this utility model provides a practical electrode fixture that can quickly switch and accurately position electrode fixtures, and can be adapted to both CNC milling machines and EDM machines.
[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: A practical electrode clamp includes a base, a first guide rail, a second guide rail, a first lead screw, a first clamping block, a second lead screw, a second clamping block, and a fixing rod. The base has a pair of clamping sidewalls forming a 90° angle. The first guide rail and the second guide rail are respectively arranged along the clamping sidewalls. The first lead screw is connected to the first clamping block. The first clamping block slides back and forth along the first guide rail to clamp the electrode in the X direction. The second lead screw is connected to the second clamping block. The second clamping block slides back and forth along the second guide rail to clamp the electrode in the Y direction. The fixing rod is detachably arranged at the bottom of the base.
[0008] Furthermore, guide rail mounting grooves are respectively provided along the two clamping sidewalls on the base plate, and the first guide rail and the second guide rail are detachably installed in the guide rail mounting grooves.
[0009] Furthermore, both the first and second guide rails are T-shaped, and the bottoms of both the first and second clamping blocks are provided with grooves that are adapted to the T-shape.
[0010] Furthermore, the ends of the first lead screw and the second lead screw are provided with mounting slots, and the corresponding first clamping block and the second clamping block are respectively provided with lead screw mounting holes. After the ends of the first lead screw and the second lead screw are respectively inserted into the lead screw mounting holes of the first clamping block and the second clamping block, they are fixed by screws inserted into the mounting slots from the side of the first clamping block and the second clamping block.
[0011] Furthermore, both the first and second lead screws are provided with threads, and the base is also provided with a detachable lead screw mounting sidewall. The lead screw mounting sidewall is provided with a matching threaded hole, and the first and second lead screws are detachably connected to the base by passing through the lead screw mounting sidewall respectively.
[0012] Compared with the prior art, the present invention has the following beneficial effects: This utility model discloses a practical electrode clamp that is suitable for electrodes of different sizes. It achieves precise positioning through clamping in the X-square and Y-direction directions. It has a simple structure, is easy to process and install. Furthermore, depending on the work section, the clamp can be quickly switched between CNC milling machines and EDM machines via a fixing rod, which greatly improves work efficiency and is suitable for large-scale promotion.

[0019] like Figures 1-2 As shown, a practical electrode clamp includes a base 2, a first guide rail 3, a first lead screw 4, a first clamping block 5, a second guide rail 6, a second lead screw 7, a second clamping block 8, and a fixing rod 9.
[0020] Specifically, the base 2 includes a base plate 2-1, clamping sidewalls 2-2, and screw mounting sidewalls 2-3. The clamping sidewalls 2-2 are a pair, which are fixed perpendicularly to each other on the base plate 2-1, forming a 90° angle, and serving as reference sides for clamping in the X and Y directions, respectively. The base plate 2-1 is provided with guide rail mounting grooves 2-4 along the two clamping sidewalls, which are used to install the first guide rail 3 and the second guide rail 6, respectively. The base 2 is also provided with screw mounting sidewalls 2-3, which are a pair, and are respectively set at the ends of the guide rail mounting grooves 2-4 through the sidewall mounting grooves.
[0021] The first lead screw 4 and the second lead screw 7 have the same structure. Both have a rotating handle at one end for easy operation, and a thread in the middle for threaded connection with the lead screw mounting side wall 2-3. The other end has a mounting groove for installation and fixing with the first clamping block 5 and the second clamping block 8. The lead screw mounting side wall 2-3 has a matching threaded hole.
[0022] The first clamping block 5 and the second clamping block 8 are slidably mounted on the first guide rail 3 and the second guide rail 6, respectively. The first guide rail 3 and the second guide rail 6 are both T-shaped and are installed in the guide rail mounting grooves 2-4, respectively. The first clamping block 5 and the second clamping block 8 have the same structure and are provided with a lead screw mounting hole in the center, which is used to install the first lead screw 4 and the second lead screw 7, respectively. After the mounting slots of the first lead screw 4 and the second lead screw 7 are inserted into the lead screw mounting hole, screws are inserted into the mounting slots from both sides of the first clamping block 5 and the second clamping block 8 to fix the first clamping block 5 and the first lead screw 4, the second clamping block 8 and the second lead screw 7. The bottom of the first clamping block 5 and the second clamping block 8 are provided with grooves that are adapted to the T-shape, and can slide on the first guide rail 3 and the second guide rail 6, respectively.
[0023] In fact, the first guide rail 3, the first lead screw 4 and the first clamping block 5 achieve clamping of the electrode 1 from the X direction, while the second guide rail 6, the second lead screw 7 and the second clamping block 8 achieve clamping of the electrode 1 from the Y direction. Combined with the two clamping sidewalls 2-2, the electrode clamping and fixing of the electrode 1 is achieved.
[0024] The first guide rail 3, the first lead screw 4, the first clamping block 5, the second guide rail 6, the second lead screw 7, and the second clamping block 8 are all designed to be detachable in order to facilitate maintenance and replacement of parts.
[0025] The fixing rod 9 is detachably installed at the bottom of the base 2, and its end is threaded. The bottom of the base 2 is provided with a matching threaded hole. When the electrode fixture needs to be installed on a CNC milling machine as a CNC machining fixture, the fixing rod 9 can be removed. When the electrode fixture needs to be installed on an EDM machine as an EDM machining fixture, the fixing rod 9 can be installed and fixed to the chuck seat of the EDM machine. Through a simple structure, it is convenient to lock and quickly switch, realizing the adaptation of two machine tools.
[0026] The working process of the practical electrode clamp described in this embodiment: The electrode fixture is clamped on the worktable of the CNC milling machine's electromagnet and straightened with a dial indicator. The center bar of the electrode fixture is leveled to find the center of the electrode fixture, ensuring the perpendicularity and center point of the copper electrode to be installed later. The copper electrode is installed, and the first lead screw 4 and the second lead screw 7 push the first clamping block 5 and the second clamping block 8 to clamp from the X and Y directions respectively, forming a single-sided reference for precise positioning in the X and Y directions, which serves as a reference for the subsequent copper electrode processing. This eliminates the need for the three processes of straightening, leveling, and centering before workpiece processing, and the processing program can be entered directly. After processing is completed, the electrode fixture is removed, the fixing rod (4) is installed, and the fixture is quickly switched to a discharge machining fixture suitable for the discharge machine.
[0027] Insert the fixing rod (4) into the chuck seat of the discharge machine and lock it. Use a dial indicator to calibrate it and level the electrode fixture to ensure the verticality and center point of the copper electrode before processing.
[0028] The electrode clamp can quickly and accurately clamp and fix the electrode, greatly improving clamping efficiency. Furthermore, by installing and removing the fixing rod, it can lock and quickly switch between CNC milling machines and EDM machines, achieving compatibility between the two machine tools.
[0029] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
