Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamps, and in particular to a copper electrode clamping fixture. Background Technology
[0002] In mold processing, copper electrodes are often used in electrical discharge machining (EDM) to machine the mold cavity. However, since different shapes of copper electrodes are often required for mold processing, the copper electrodes need to be machined. In traditional processes, a fixture is used to fix the copper electrode on the worktable, and a cutting tool is used to carve the electrode. After machining, the electrode is removed from the fixture and placed in a new fixture for further machining. This method can only machine one electrode at a time, requiring a fixing and removal operation for each machining cycle, which is not only complex but also time-consuming, affecting the machining efficiency. Therefore, those skilled in the art have provided a copper electrode clamping fixture to solve the problems mentioned in the background section. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a copper electrode clamping fixture that avoids the wear and tear that occurs when using bolts for fastening in traditional technologies, as well as the specificity of requiring wrenches for disassembly and assembly.

[0005] A copper electrode clamping fixture includes a base, mounting seats fixed at the four corners of the upper end of the base, and adjusting rods threaded onto the upper end of the mounting seats. An inner shell is fixedly installed inside the adjusting rod near the upper end. Limiting components are installed on both sides of the inner shell. A pressing component for pressing the two limiting components to move outward is installed at the midpoint of the inner shell above the two limiting components. A top cover is fixedly installed on the upper end of each of the adjusting rods.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Reference Figures 1-6 This utility model provides an embodiment of a copper electrode clamping fixture, including a base 4, mounting seats 3 fixed at the four corners of the upper end of the base 4, and adjusting rods 2 threadedly installed on the upper end of the mounting seats 3. An inner shell 10 is fixedly installed inside the adjusting rod 2 near the upper end. Limiting components 9 are installed on both sides inside the inner shell 10. A pressing component 6 for pressing the two limiting components 9 to move outward is installed at the midpoint of the inner shell 10, located above the two limiting components 9. A top cover 5 is fixedly installed on the upper end of the multiple adjusting rods 2. By installing the copper electrode onto the mounting seat 3 and passing it through the adjusting rod 2, and then pushing the limiting components 9 inside the adjusting rod 2 outward and then twisting the adjusting rod 2 downward to adjust the height position of the limiting components 9, the upper surface of the copper electrode is pressed, restricted, and fixed.
[0024] Reference Figure 1 The rear end face of the base 4 is hinged with a cover plate 1;
[0025] Specifically, by providing a flip-up cover 1 at the top, the cover 1 can be flipped onto the top of the base 4 after use to cover and protect the entire fixture.
[0026] Reference Figure 3 A threaded hole 8 is provided at the midpoint of the upper end face of the mounting base 3, and the lower end of the adjusting rod 2 is threaded into the threaded hole 8;
[0027] Specifically, during use, the adjusting rod 2 can be twisted to move it downwards. At this time, the height position of the limiting component 9 on the adjusting rod 2 changes, thereby changing the distance between it and the upper surface of the copper electrode to achieve the clamping and fixing effect.
[0028] Reference Figure 3 The limiting component 9 includes a connecting block 901. A limiting plate 903 is fixedly installed at the lower end of one side of the connecting block 901, and a spring 902 is fixedly installed at the upper end of one side. A connecting port 7 is opened at the upper end of both sides of the outer wall of the adjusting rod 2. The limiting plate 903 is movably installed in the connecting port 7. The connecting port 7 is in communication with the inner cavity of the inner shell 10. The end of the spring 902 away from the connecting block 901 is fixedly connected to one side of the inner wall of the inner shell 10.
[0029] Specifically, when the connecting block 901 moves under force, the lower limiting plate 903 moves together. At this time, the limiting plate 903 moves outward from inside the connecting port 7. The limiting plate 903 is exposed to the outside, thus playing an auxiliary limiting role on the upper surface of the copper electrode placed at the lower end, preventing it from sliding upward from the adjusting rod 2. The spring 902 automatically recovers and retracts after the force is applied, without the need for manual secondary adjustment.
[0030] Reference Figure 3 The upper end face of the connecting block 901 is inclined on one side, and the lower end face of the extrusion component 6 is located on the inclined cut surface;
[0031] Specifically, by utilizing the inclined cut structure designed at the upper end, when the extrusion component 6 moves downward, it will generate an extrusion pushing force on the connecting block 901, thereby causing the connecting block 901 to move laterally to one side, thus achieving the shrinking and unfolding effect of the limiting component 9.
[0032] Reference Figure 3 The extrusion assembly 6 includes a torsion bar 601, which is threaded onto the top cover 5 and passes through the lower end of the top cover 5 and is rotatably connected to the extrusion block 602 via a bearing.
[0033] Specifically, during use, the torsion bar 601 can be screwed onto the top cover 5. During the screw rotation, a downward movement is observed. Since the lower end of the torsion bar 601 is rotatably connected to the extrusion block 602, the extrusion block 602 will not rotate and will be embedded in the inner housing 10. The inner housing 10 is rectangular and the extrusion block 602 is also rectangular, so the extrusion block 602 will not rotate. Under the action of the torsion bar 601, it will move downward, ultimately realizing the function of the extrusion block 602 moving downward and pushing the limiting component 9.
[0034] Working principle: When in use, the copper electrode is placed on the mounting base 3 by passing it through the adjusting rod 2. Then, the torsion rod 601 is turned to move it downward and push the lower end of the extrusion block 602 to move downward, thereby achieving the pushing and extruding effect on the limiting component 9.
[0035] Secondly, during the pushing process of the extrusion block 602, the inclined cut structure designed on the upper end of the connecting block 901 causes it to move laterally to one side. When the connecting block 901 is moved by force, it will drive the lower limiting plate 903 to move together. At this time, the limiting plate 903 will move outward from the inside of the connecting port 7. At this time, the limiting plate 903 is exposed to the outside, thus playing an auxiliary limiting effect on the upper surface of the copper electrode placed at the lower end, preventing it from sliding upward from the adjusting rod 2. The function of the spring 902 is to automatically recover and retract after the force is applied, without the need for manual secondary adjustment.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing 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. 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.
