Therefore, EDM technology has been widely applied in mold manufacturing, aerospace, medical devices, and many other fields. Typically, this machining process is completed using specialized EDM machine tools, but existing equipment still has certain shortcomings, such as: Application CN202420606966.9, entitled "An Electrode Positioning Clamping Device for an EDM Machine," includes: a fixed base, an adjusting plate, a rotating base, a locking device, a fixing sleeve, a clamping sleeve, and a fixing rod. The adjusting plate is installed at the bottom of the fixed base by adjusting bolts, and a spherical component is provided at the center between the fixed base and the adjusting plate.

Therefore, an electrode positioning clamping device for an EDM machine is proposed to solve the above problems. Utility Model Content

[0016] Compared with existing technologies, the advantages of this utility model are as follows: Through structural design including a worm gear, limiting plate, worm wheel, and tripod, this utility model achieves precise placement and secure clamping of the electrode post; simultaneously, the inclusion of traction holes and traction wires enhances the overall stability of the tripod, effectively preventing electrode post offset and wobbling during processing, thus improving the accuracy and efficiency of electrode post processing; furthermore, the threaded hole design on the equipment plate simplifies the installation and disassembly process and improves the stability and reliability of the entire clamping equipment, allowing users to make flexible adjustments according to actual needs.

[0017] 1. When using, first fix the equipment plate to the EDM machine body with bolt assembly, then the operator holds the lower end of the electrode column and places the upper part of the electrode column on the inner end face of the tripod. 2. Then, with the other hand, control the switch to start the drive motor. The drive motor drives the worm gear to rotate clockwise, which in turn drives the worm wheel to rotate. This causes the worm wheel to drive the tripod to clamp the electrode post body in a centered manner. Furthermore, the anti-slip pads on the inner end face of the tripod increase the friction between the electrode post and the tripod, ensuring that the electrode post will not slip due to vibration during electrical discharge machining. 3. The two ends of the traction wire are fixed in the traction holes on the adjacent inner walls of the tripod to form a stable triangular structure. This design further enhances the stability of the tripod when clamping the electrode post. Attached Figure Description

The meshing transmission of worm gear 7 and worm 5 facilitates precise angle adjustment and stable clamping force; this design not only improves the positioning accuracy of the electrode post, but also ensures stability and reliability during the clamping process. A tripod 8 is welded onto the worm gear 7, and an anti-slip pad is fixedly connected to the inner end of the tripod 8 to prevent the electrode post from sliding or loosening due to vibration or external force during clamping, thereby further improving the stability and reliability of the electrode post clamping. The design of the tripod 8 increases the contact area between the clamping point and the electrode post, making the clamping more secure, while the use of the anti-slip pad effectively prevents wear on the surface of the electrode post and protects the integrity of the electrode post. Traction holes are provided on the inner end face of the tripod 8, and traction wires 9 are provided in the traction holes on the adjacent inner walls of the tripod 8. This helps to enhance the overall stability of the tripod 8, making it less likely for the electrode post to shift or shake during processing, and further improving the accuracy and efficiency of electrode post processing. A threaded hole is provided on the upper end face of the equipment plate 1, and the threaded hole is circumferentially arranged about the center of the equipment plate 1, which facilitates the fixed connection between the equipment plate 1 and the EDM machine body, improving the stability and reliability of the entire clamping equipment; at the same time, the design of the threaded hole makes the installation and disassembly process simpler and faster, allowing users to make flexible adjustments according to actual needs, thus improving the practicality and convenience of the equipment. Working principle: When in use, first fix the equipment plate 1 to the EDM machine body with bolt assembly, then the operator holds the lower end of the electrode column and places the upper part of the electrode column on the inner end face of the tripod 8. Then, with the other hand, control the switch to start the drive motor 4. The drive motor 4 drives the worm 5 to rotate clockwise, and the worm 5 drives the worm wheel 7 to rotate, which in turn drives the tripod 8 to clamp the electrode post body in a centered manner. Furthermore, the anti-slip pad on the inner end face of the tripod 8 increases the friction between the electrode post and the tripod 8, ensuring that the electrode post will not slip due to vibration during electrical discharge machining. The two ends of the traction wire 9 are fixed in the traction holes on the adjacent inner walls of the tripod 8 to form a stable triangular structure. This design further enhances the stability of the tripod 8 when clamping the electrode post.
