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] Example 1

[0024] like Figures 1 to 5 As shown, a C-axis electrode forming device for an EDM machine includes a processing table 1. An adjustment component 2 is provided at one end of the top side of the processing table 1, a fixing mechanism 3 is provided on the top side of the adjustment component 2, and a clamping component 4 is provided at the middle position of the top side of the processing table 1. The adjustment component 2 includes a base plate 21, which is fixed to one corner of the top side of the processing table 1. A spherical groove 22 is provided at the center of the top side of the base plate 21. A sphere 23 is rotatably installed inside the spherical groove 22. A top plate 24 is rotatably installed on the top side of the sphere 23. Rotation grooves 25 are provided at the four corners of the top side of the base plate 21 and the bottom side of the top plate 24. A rotating block 26 is rotatably installed inside the bottom rotation groove 25, and a connecting block 29 is rotatably installed inside the top rotation groove 25. A threaded cylinder 27 is fixed on the top side of the rotating block 26, and a threaded rod 28 is fixed on the bottom side of the connecting block 29.

[0025] Furthermore, the threaded rod 28 is rotatably mounted inside the threaded cylinder 27 via a threaded engagement. The rotating block 26 and the connecting block 29 are spherical structures. The threaded engagement provides precise transmission and enables fine control of the height and angle of the top plate 24. The spherical rotating block 26 and the connecting block 29 are adapted for multi-directional adjustment to avoid jamming during the adjustment process.

[0026] Furthermore, the base plate 21 and the top plate 24 are square structures. A detection probe 5 is provided at one end of the base plate 21. The detection probe 5 is fixed at one corner of the top side of the processing table 1. The detection probe 5 can accurately detect the electrode position, which is convenient for quick adjustment, reduces processing errors, and ensures the electrode forming accuracy.

[0027] Example 2

[0028] Improvements based on Example 1:

[0029] Furthermore, the fixing mechanism 3 includes a base 31, which is fixed at the center of the top side of the top plate 24. A limiting plate 32 is symmetrically fixed on the top side of the base 31. The base 31 provides stable support for electrode fixing, and the symmetrically arranged limiting plates 32 ensure balanced force, thereby accurately clamping the electrode body 36.

[0030] Furthermore, an adjusting rod 33 is rotatably inserted into the inner side of the limiting plate 32 via a threaded connection. One end of the adjusting rod 33 is fixed with a limiting block 34, and the limiting block 34 is rotatably connected to the clamping plate 35 to prevent the clamping plate 35 from shifting during adjustment and to improve clamping accuracy.

[0031] Furthermore, a clamping plate 35 is symmetrically slidably installed on the inner side of the base 31. The clamping plate 35 is rotatably connected to the limiting block 34. The electrode body 36 is clamped on the inner side of the clamping plate 35. The clamping plate 35 has a symmetrical sliding design, so the force is evenly distributed when clamping, avoiding deformation or displacement of the electrode body 36, and can stably clamp electrodes of different specifications.

[0032] Furthermore, the clamping assembly 4 includes a fixed platform 41, which is fixed at the middle position on the top side of the processing table 1. A fixed plate 42 is fixed at one end of the top side of the fixed platform 41, and a movable plate 43 is slidably installed on the top side of the fixed platform 41. A rectangular groove 44 is provided on the top side of the fixed platform 41. The fixed platform 41 provides a stable platform for workpiece clamping. The fixed plate 42 and the movable plate 43 cooperate to realize bidirectional clamping of the workpiece, thereby accurately clamping and fixing the workpiece in the processing position.

[0033] Furthermore, a lead screw 45 is rotatably mounted inside the rectangular groove 44. One end of the lead screw 45 passes through the fixed platform 41 and is fixed to a turntable 47. A connecting ear 46 is fixed to the bottom side of the moving plate 43. The connecting ear 46 is rotatably connected to the lead screw 45 and is slidably mounted inside the rectangular groove 44. The position of the moving plate 43 can be adjusted by the turntable 47. The rectangular groove 44 plays a guiding and limiting role for the connecting ear 46, ensuring that the moving plate 43 slides smoothly and that the positioning is accurate and the stability is strong when clamping the workpiece.

[0034] Working principle: During processing, the workpiece is placed inside the fixed platform 41 on the top side of the processing table 1, and the turntable 47 is rotated to drive the lead screw 45 to rotate. With the cooperation of the connecting lug 46, the moving plate 43 slides along the rectangular groove 44, causing the moving plate 43 to clamp and fix the workpiece in the processing position with the cooperation of the fixed plate 42. At this time, the EDM machine can process the workpiece through the electrode fixed to its C-axis. If the electrode is worn and needs to be replaced, the electrode body 36 can be placed inside the clamping plate 35, and the electrode body 36 can be clamped and fixed to the clamping plate 35 by rotating the adjusting rod 33. 5. Next, rotate the threaded rod 28 on the bottom side of the top plate 24 to adjust the electrode body 36 on the top side of the top plate 24 to the required concentricity and levelness through extension and retraction. At this time, the electrode body 36 can be processed by the electrode fixed by the C-axis of the EDM machine. During the forming process, the C-axis rotates at high speed to ensure the uniformity of the electrode. At the same time, the electrode is also in a high-speed rotation state to ensure the roundness of the processing position. After the processing is completed, the electrode body 36 is accurately installed into the EDM machine with the cooperation of the detection probe 5, and the workpiece is processed again to improve the working efficiency of the EDM machine.
