A coupling is installed between the output end of the motor 11 and the lead screw 12. One end of the lead screw 12 rotates on the mounting frame 4. A threaded block 13 is welded to the bottom of the moving frame 5. The threaded block 13 is threaded to the outer peripheral wall of the lead screw 12. Two guide rails 14 are welded to the moving frame 5. The guide rail 9 is perpendicular to the guide rail 14. A slider 15 for sliding on the guide rail 14 is welded to the bottom of the moving pile 6. A motor 16 is installed on the moving frame 5 by bolts. The motor 16 is located below the moving pile 6. The output end of the motor 16 is rotatably connected to the lead screw 17. A coupling is installed between the output end of the motor 16 and the lead screw 17. The axial direction of the lead screw 12 is perpendicular to the axial direction of the lead screw 17. A threaded block 18 is welded to the bottom of the moving pile 6. The threaded block 18 is threaded to the outer peripheral wall of the lead screw 17.

[0021] Two vertically arranged mounting strips 19 are welded to the inner top wall of the movable pile 6. The movable pile 6 is hollow inside, with an opening on the side near the connecting arm 7. A guide rail 20 is welded to the mounting strips 19. A movable plate 21 is welded to the side of the connecting arm 7 near the movable pile 6. A slider 22 that slides on the guide rail 20 is welded to the movable plate 21. A lead screw 23 is connected to the inside of the movable pile 6 via a motor 3. Both the guide rail 20 and the lead screw 23 are vertically arranged. A threaded block 24 is welded to the movable plate 21 and is threaded to the outer peripheral wall of the lead screw 23. The cross-sections of the guide rail 1 9, guide rail 2 14, and guide rail 20 are all I-shaped. The sliders 10, 15, and 22 are all designed with an inverted U-shape cross-section. The outer walls of the lead screws 12, 17, and 23 are all machined with external threads. The internal threads of the threaded blocks 13, 18, and 24 are all machined with internal threads. The end of the connecting arm 7 near the storage tray 2 has a motor 4 25 embedded in it. The rotating arm 8 is bolted to the output end of the motor 4 25. The workbench 3 is equipped with a central control screen 26, which is used to control the motors 11, 16, 3, and 25. The motors 11, 16, 3, and 25 are all connected to the central control screen 26 by wires.

[0022] Two detachable accordion dust covers 27 are connected to the mounting frame 4. The movable frame 5 is located between the two accordion dust covers 27, and the movable frame 5 is in close contact with the two accordion dust covers 27. The accordion dust covers 27 are located above the lead screw 12 and the motor 11. Two detachable accordion dust covers 28 are connected to the movable frame 5. The bottom end of the movable pile 6 is located between the two accordion dust covers 28 and is in close contact with each other. The lead screw 17 and the motor 16 are both located below the accordion dust covers 28. Inside the movable pile 6... The wall is detachably connected to two accordion dust covers 29. The movable plate 21 is located between the two accordion dust covers 29 and fits against them. Accordion dust covers 27, 28 and 29 are all made of PVC material. The mounting frame 4, movable frame 5 and movable pile 6 are all threaded with screws 30. Accordion dust covers 27, 28 and 29 are all provided with threaded holes for connecting with screws 30.

[0023] The user places the material to be processed on the storage tray 2. Then, when the user starts motor 11 via the touchscreen 26 and rotates its output clockwise, motor 11 drives lead screw 12 to rotate clockwise. As lead screw 12 rotates, it drives threaded block 13, slider 10, and moving frame 5 towards the storage tray 2, causing moving frame 5 to move on mounting frame 4. Sliding slider 10 slides on guide rail 9, providing guidance. As moving frame 5 moves towards storage tray 2, it drives moving post 6, connecting arm 7, rotating arm 8, and EDM head 1 to move. At this time, the accordion dust cover 27 near storage tray 2 is gradually squeezed by moving frame 5, while the accordion dust cover 27 away from storage tray 2 gradually recovers its shape until EDM head 1 approaches storage tray 2 and processes the material. By adjusting motor 11 to rotate counterclockwise, it drives lead screw 12 to rotate. 2. The counterclockwise rotation drives the threaded block 13, the slider 10, and the moving frame 5 to move away from the storage tray 2. When the moving frame 5 moves away from the storage tray 2, it drives the moving stake 6, the connecting arm 7, the rotating arm 8, and the EDM head 1 to move. At this time, the accordion dust cover 27 near the storage tray 2 gradually recovers its deformation, while the accordion dust cover 27 away from the storage tray 2 is gradually squeezed by the moving frame 5. This makes the two accordion dust covers 27 always cover the lead screw 12 and the motor 11 to prevent dust when the moving frame 5 moves back and forth in the direction of approaching or away from the storage tray 2. Thus, the moving frame 5 can be moved back and forth on the mounting frame 4 in the direction of approaching or away from the storage tray 2. When the moving frame 5 moves, it drives the moving stake 6, the connecting arm 7, the rotating arm 8, and the EDM head 1 to move, so that the EDM head 1 can move back and forth on the worktable 3 to adjust the distance between the EDM head 1 and the storage tray 2.

[0024] When the user starts motor 16 via the touch screen 26 and rotates its output clockwise, motor 16 drives lead screw 17 to rotate clockwise. The clockwise rotation of lead screw 17 causes slider 15, threaded block 18, and moving post 6 to move horizontally away from the touch screen 26. This causes moving post 6 to move on moving frame 5, while slider 15 slides on guide rail 14. As moving post 6 moves away from the touch screen 26, it presses against the accordion dust cover 28, which is away from the touch screen 26. Meanwhile, the accordion dust cover 28, which is closer to the touch screen 26, gradually recovers its shape. The movement of moving post 6 also drives connecting arm 7, rotating arm 8, and EDM head. 1. When the output end of motor 16 is rotated counterclockwise by adjusting motor 16, motor 16 drives lead screw 17 to rotate counterclockwise. When lead screw 17 rotates counterclockwise, it drives slider 15, threaded block 18 and moving post 6 to move towards the central control screen 26. At this time, the accordion dust cover 28 away from the central control screen 26 gradually returns to its original shape, while the accordion dust cover 28 close to the central control screen 26 is gradually squeezed by the bottom end of moving post 6. This allows the EDM head 1 to move left and right on the worktable 3. When moving post 6 moves left and right in the direction of approaching or away from the central control screen 26, the two accordion dust covers 28 always cover lead screw 17 and motor 16 to prevent dust.

[0025] When the user starts the motor three via the touch screen 26 and rotates the output end of the motor three clockwise, the motor three drives the lead screw three 23 to rotate clockwise. When the lead screw three 23 rotates clockwise, the threaded block three 24 moves downward. When the threaded block three 24 moves downward, it drives the moving plate 21, the connecting arm 7, the rotating arm 8, and the EDM head 1 to move downward respectively. When the moving plate 21 moves, it drives the slider three 22 to slide on the guide rail three 20. When the moving plate 21 moves downward, it will squeeze the accordion dust cover three 29 near the moving frame 5, while the accordion dust cover three 29 away from the moving frame 5 gradually returns to its original shape. When the output end of the motor three is adjusted to rotate counterclockwise, at this time... Motor 3 drives lead screw 3 23 to rotate counterclockwise. When lead screw 3 23 rotates counterclockwise, threaded block 3 24 moves upward. When threaded block 3 24 moves upward, it drives slider 3 22, moving plate 21, connecting arm 7, rotating arm 8 and EDM head 1 to move upward respectively. At this time, the accordion dust cover 3 29 close to the moving frame 5 gradually recovers its deformation, while the accordion dust cover 3 29 far from the moving frame 5 is gradually squeezed by moving plate 21, so that EDM head 1 can move up and down on the worktable 3 to adjust the working height of EDM head 1. When connecting arm 7 and moving plate 21 move up and down, the two accordion dust covers 3 29 always cover lead screw 3 23 and motor 3 to prevent dust.

[0026] When the user starts motor 4 25 via the touch screen 26 and rotates the output of motor 4 25 clockwise, motor 4 25 drives the rotating arm 8 and the EDM head 1 to gradually rotate upward toward the tray 2. When motor 4 25 is adjusted to rotate counterclockwise, motor 4 25 drives the rotating arm 8 and the EDM head 1 to gradually rotate downward away from the tray 2 to adjust the tilt angle of the EDM head 1. This allows adjustment of the EDM head 1's operating angle on the worktable 3, facilitating the adjustment of the EDM head 1's position on the worktable 3 for processing materials on the tray 2 at different locations. Furthermore, the central control screen 26 enables precise control of motors 1 11, 2 16, 3, and 4 25, resulting in more accurate material processing when the EDM head 1 is positioned at different locations on the worktable 3.

[0027] When the top surface of the accordion dust cover 27, 28, or 39 is covered with a lot of dust and needs to be removed for cleaning, the user can remove the accordion dust cover 27 from the mounting frame 4 by holding and rotating the screw 30 located on the mounting frame 4, so that the screw 30 on the mounting frame 4 disengages from the threaded hole on the accordion dust cover 27 for cleaning. Similarly, the user can remove the accordion dust cover 28 from the moving frame 5 by rotating the screw 30 located on the moving post 6, so that the accordion dust cover 29 can be removed from the moving post 6 for cleaning and replacement.
