[0034] The electroporator 1 comprises a bottom plate 11, on which a magnet 12 is adsorbed, a column 13 is fixedly connected to the top of the magnet 12, an insulating plate 14 is arranged on the column 13, a side plate 141 is arranged on one side of the insulating plate 14, the side plate 141 is fixedly connected to the column 13, a guide rail 15 is fixedly connected to the side of the insulating plate 14 away from the side plate 141, a lifting component 16 is arranged on the insulating plate 14, a high-pressure water zone 17 is arranged on the lifting component 16, a rotating motor 18 is arranged on the lifting component 16, and an electroporation component 19 is arranged at the bottom of the high-pressure water zone 17. The bottom plate 11 is made of iron material. When processing a large workpiece, the large workpiece serves as the bottom plate. The magnet 12 ensures the installation stability of the electroporator 1. The electroporator 1 can be installed on an upper fixed frame of a machine tool with an X and Y table (for example, an upper wire frame of a wire cutting machine, an upper frame of a milling machine) through the magnet 12 to process electroporation or electric pulses on the workpiece from top to bottom. , numerical control or manual X, Y axis data control multiple relative size positions (some workpieces need to process multiple holes at different positions), the column 13 is used to provide support for the electroporator 1, the insulating plate 14 is used to isolate the current in the circuit, so that the current is concentrated on the processed workpiece to speed up the processing speed, the side plate 141 is used to fix the insulating plate 14 on the column 13, the guide rail 15 is used to provide guidance for the lifting component 16, the lifting component 16 drives the electroporation component 19 to adjust the upper and lower positions, and the upper and lower limit switches are set on the side of the insulating plate 14 to limit the lifting component 16 to prevent it from being too upward or downward. The high-pressure water area 17 is used to connect the water pipe of the high-pressure water pump 3 and to receive the electroporation component 19. The rotating motor 18 is rotated to drive the electroporation component 19 to rotate accordingly. The electroporation component 19 is used to perform electric spark perforation and electric spark electric pulse on the workpiece.

[0035] Specifically, the lifting component 16 includes a lifting motor 161 fixedly connected to the insulating plate 14, a screw rod 162 is fixedly connected to the output end of the lifting motor 161, and the external thread of the screw rod 162 is connected to the moving platform 163. The lifting motor 161 is used to provide driving force for the screw rod 162, the screw rod 162 is used to support the moving platform 163, and the moving platform 163 is used to support the high-pressure water area 17 and the rotating motor 18.

[0036] Furthermore, the end of the screw rod 162 is rotatably connected to the base of the insulating plate 14, and the end of the movable platform 163 is slidably connected to the guide rail 15. When the screw rod 162 rotates, the movable platform 163 threadedly connected to the screw rod 162 slides in the guide rail 15 and is limited by the guide rail 15.

[0037] Furthermore, an interface 171 is provided at the top of the high-pressure water zone 17, and a synchronous wheel 172 is rotatably connected to the bottom of the high-pressure water zone 17. A synchronous belt 181 is provided on the output end of the rotating motor 18 and the outer sleeve of the synchronous wheel 172. The interface 171 is used to connect the water pipe of the high-pressure water pump 3, and the synchronous wheel 172 is used to receive the drill chuck 191. When the rotating motor 18 is started, its output end rotates accordingly, and through the synchronous belt 181, the synchronous wheel 172 is driven to rotate synchronously at the bottom of the high-pressure water zone 17.

[0038] Furthermore, the electroporation component 19 includes a drill chuck 191 inserted into the bottom of the synchronous wheel 172, a ruby ​​guide 192 is provided at the bottom of the base of the insulating plate 14, and an electrode copper tube 193 is provided in the drill chuck 191. The drill chuck 191 is used to fix the electrode copper tube 193 and the copper rod 194 inside it to ensure that they will not fall off or shake during the drilling operation. The ruby ​​guide 192 is used to ensure that the electrode copper tube 193 can maintain a stable guiding effect during the processing process to reduce the risk of tool shaking or deviation. The processing error caused by this ensures the guiding accuracy during the processing, thereby improving the accuracy of the processed workpiece. The electrode copper tube 193 is a brass tube with a diameter of 0.3-4mm. The small round hole is processed from top to bottom on the workpiece. The copper tube with a diameter of 1mm and a current of 10A can be processed with a white steel knife at a depth of about 30mm per minute. The electrode copper tube 193 and a high-pressure water pump 3 are used. At the same time, they can be universally adjusted to process at any angle. The test power is 2220 watts. The theoretical calculation has a current of 24A and a depth of 60mm per minute, which is twice the traditional speed.

[0039] Furthermore, a hole is opened on the base of the insulating plate 14 , and the electrode copper tube 193 passes through the hole and the ruby ​​guide 192 .

[0040] Furthermore, the electroporation component 19 also includes a copper rod 194 and an electrolytic copper block 195. The electrolytic copper block 195 can use various special-shaped copper electrodes (the shape can be rectangular, polygonal, elliptical, text, characters and other required shapes). The workpiece is processed from top to bottom to the required depth (the material of the workpiece: alloy steel, quenched hard material, titanium alloy, aluminum, ordinary iron and other conductive materials) and the workpiece is immersed in kerosene to remove carbon deposits.

[0041] Furthermore, the outer diameter of the copper rod 194 is smaller than the maximum diameter of the drill chuck, and the copper rod 194 and the electrolytic copper block 195 are threadedly connected.

[0042] As can be seen from the above, when electroporation is performed, an electrode copper tube 193 with a diameter of 0.3-4 mm is clamped on the drill chuck 191 and fixed. The electrode copper tube 193 passes through the ruby ​​guide 192 below, exposing a length of about 10 mm, and is aligned with the position to be processed on the workpiece. Press the depth setting button on the controller 4, press the rotation button (the electrode three-jaw chuck starts to rotate), and then press the water pump button (water from the high-pressure water pump 3 is sprayed from the center of the electrode copper tube 193), then press the start button, and then turn on the power tube main switch on the pulse power supply cabinet 5, rotate the rotary motor 18 clockwise, and the electrode copper tube 193 rotates to discharge the workpiece and break down the conductive workpiece. The processing stops at the set depth, and the processing and perforation of the workpiece is completed;

[0043] When using electric spark pulse, remove the ruby ​​guide 192 and the electrode copper tube 193, replace them with a 4mm diameter copper rod 194, pass the copper rod 194 through the hole opened on the base of the insulating plate 14, clamp it in the drill chuck 191 for fixing, and the bottom of the copper rod 194 is threadedly connected with an electrolytic copper block 195. When processing small workpieces, directly immerse the workpiece in the kerosene of the water tank 2, and turn off the high-pressure water pump 3. When processing large workpieces, remove the water pipe of the high-pressure water pump 3 connected to the top interface 171 of the high-pressure water zone 17, flush the water outlet at the workpiece processing position, tighten the copper rod 194 and the electrolytic copper block 195 with threads, press the depth setting button on the controller 4, press the cycle lifting button, press start, and then turn on the power tube main switch on the pulse power supply cabinet 5, rotate clockwise, rotate the motor 18, start discharge processing of the conductive workpiece, and the electrolytic copper block 195 moves forward three steps and back one step. When the depth processing stops, the processing and perforation of the workpiece are completed;

[0044] Through the detachable and replaceable ruby ​​guide 192, electrode copper tube 193, copper rod 194 and electrolytic copper block 195, the limitation of traditional EDM perforators and EDM electric pulse machines that they can only perform a single function is broken through, the two are integrated into one, and universal processing is realized. The electrode copper tube 193 can be used for electroporation processing, and various special-shaped electrolytic copper tubes can be used as electrodes for electric pulse processing, which meets the processing requirements of different workpiece materials and greatly enhances the versatility and flexibility of the equipment. Tap water or clean water is used as the working fluid during electroporation. Kerosene working fluid is the fastest for the working electrode during electric pulse. Clean water can also be used but the processing speed will be slightly reduced, which improves the processing flexibility and adaptability. It is easier to remove broken screws, broken drill bits, and broken taps. Compared with traditional methods, it reduces labor costs and improves efficiency. It has a five-speed power adjustment function and stepless speed regulation, which is convenient for users to adjust according to different processing needs.
