[0022] Please see Figures 1-4 This utility model provides a technical solution:
[0023] A liquid filling device for an EDM machine includes a liquid filling device body 1 and a liquid storage tank 2. The liquid storage tank 2 is fixedly connected to the top of the liquid filling device body 1. A connecting pipe 3 is fixedly connected to the top of the liquid storage tank 2. A connecting groove 4 is opened at the top of the connecting pipe 3. A sealing ring 5 is provided inside the connecting groove 4. A connecting ring 6 located inside the connecting groove 4 is fixedly connected to the top of the sealing ring 5. A first filter screen 7 is fixedly connected to the top of the connecting ring 6. A fixing shell 8 is threadedly connected to the outside of the connecting pipe 3. A fixing ring 9 is fixedly connected to the outside of the fixing shell 8. A magnetic ring 10 is magnetically connected to the top of the fixing ring 9. A fixing cover 11 located at the top of the fixing ring 9 is fixedly connected to the top of the magnetic ring 10. A support ring 12 is fixedly connected to the inside of the fixing shell 8. A second filter screen 13 is provided between the support ring 12 and the fixing cover 11. A rotating shaft 14 is connected to the inside of the second filter screen 13. A cleaning brush 15 located at the top of the first filter screen 7 and the second filter screen 13 is fixedly connected to the outside of the rotating shaft 14. A handle 16 is fixedly connected to the top of the rotating shaft 14.
[0024] The inner shape of the connecting groove 4 matches the shape of the sealing ring 5 and the connecting ring 6 combined together, and the inner size of the connecting groove 4 matches the size of the sealing ring 5 and the connecting ring 6 combined together. The connecting groove 4, the sealing ring 5 and the connecting ring 6 can effectively prevent the dielectric liquid from entering the storage tank 2 directly without passing through the first filter screen 7, thus affecting the purity of the dielectric liquid. The outer shape of the second filter screen 13 matches the inner shape of the fixed shell 8, and the outer diameter of the second filter screen 13 matches the inner diameter of the fixed shell 8, so as to ensure that the second filter screen 13 and the fixed shell 8 fit together perfectly and can be accurately locked into the fixed shell 8. The diameter of the fixed ring 9 matches the diameter of the magnet ring 10, and the diameter of the fixed cover 11 is larger than the diameter of the magnet ring 10 and the fixed ring 9, which is conducive to gripping the fixed cover 11 and making it easier to exert force. The bottom end of the upper cleaning brush 15 is in contact with the top end of the second filter screen 13, and the bottom end of the lower cleaning brush 15 is in contact with the top end of the first filter screen 7.
[0025] Workflow: When using a liquid-feeding device for an EDM machine, the entire device is powered externally. The dielectric liquid is poured into the fixed housing 8 through the opening above the fixed cover 11. First, the dielectric liquid is filtered through the second filter screen 13. Then, the dielectric liquid passing through the second filter screen 13 undergoes a second filtration through the first filter screen 7. The second filter screen 13 reduces the filtration pressure on the first filter screen 7, while also reducing impurities and making the dielectric liquid purer. The connecting groove 4, connecting ring 6, and sealing ring 5 provide a seal between the first filter screen 7 and the connecting pipe 3, preventing the dielectric liquid from bypassing the first filter screen 7 and directly entering the storage tank 2, thus preventing impurities from damaging the liquid-feeding device body 1. Finally, the dielectric liquid is stored in the storage tank 2. The liquid-feeding device body 1 draws the dielectric liquid from the storage tank 2 to power the EDM machine. The handle 16 allows easy rotation of the rotating shaft 14 and cleaning brush 15. The cleaning brush 15 cleans the first filter screen 7 and the second filter screen 13, extending the lifespan of the first filter screen 7 and the second filter screen 13 to some extent. The replacement cycle of the second filter screen 13 is shortened, reducing the frequency of replacement. When the filter structure needs to be replaced, simply pull up the fixing cover 11 to separate it from the fixing shell 8. Remove the cleaning brush 15 and the second filter screen 13 together for replacement. By rotating the fixing shell 8, it can be separated from the connecting pipe 3. Then, the first filter screen 7 can be easily pulled out for replacement without disassembling the liquid adding device body 1, which is more convenient. Then, insert the connecting ring 6 and sealing ring 5 below the new first filter screen 7 into the connecting groove 4. Then, fix the first filter screen 7 by connecting the fixing shell 8 and the connecting pipe 3. Next, put the second filter screen 13, the rotating shaft 14, and the cleaning brush 15 directly into the fixing shell 8. The second filter screen 13 is supported by the support ring 12. Then, the fixing cover 11 is snapped onto the top of the fixing shell 8. The fixing cover 11 and the fixing ring 9 are magnetically connected by the set magnetic ring 10. The second filter screen 13 is fixed by fixing the fixing cover 11 and the support ring 12. The above operations can quickly complete the disassembly and installation of the filter structure.
