[0027] During specific use, through the arrangement of refrigerator 3, water pump 5, delivery pipe 6, serpentine pipe 7 and return pipe 8, partition 2 divides the interior of shell 1 into three use spaces, wherein the space at the bottom stores coolant, and the space in the upper half stores working fluid, which is used for the electrical corrosion generated when the spark machine discharges. Bracket 4 protects refrigerator 3 to prevent it from falling. When refrigerator 3 is started, the coolant is cooled down. Delivery pipe 6 delivers the cooled coolant to the interior of serpentine pipe 7 through water pump 5, so as to quickly cool down the working fluid. Moreover, serpentine pipe 7 is a curved pipe, and the temperature of each point is consistent. While quickly cooling down, the processing quality will not be affected by inconsistent temperature, thus saving working time and improving product quality. Return pipe 8 delivers the coolant after heat exchange back to the lower half space inside shell 1, and then reuses it, so that the coolant keeps circulating, the cooling effect is enhanced, and the practicability is high. Pipe clamp 9 fixes serpentine pipe 7 to ensure stability during use.
[0028] In this embodiment, a processing table 10 is fixedly connected to the middle of the upper surface of the partition 2. A guide groove 11 is opened on the upper surface of the processing table 10. A bidirectional screw 12 is rotatably connected inside the guide groove 11. The first slider 13 is threadedly connected to both sides of the outer surface of the bidirectional screw 12.
[0029] During specific use, the bidirectional screw 12 is set and rotated to make the two first sliders 13 on its outer surface move closer to or separate from each other, thereby adjusting the positions of the two clamps 14 according to the size of the workpiece, thereby expanding the use range of the device. The guide groove 11 can guide the first slider 13 so that it can only move horizontally inside the guide groove 11.
[0030] In this embodiment, a clamping plate 14 is fixedly connected to the upper surface of the first sliding block 13 , and a rubber pad 15 is fixedly connected to the inner side surface of the clamping plate 14 .
[0031] When in use, the two clamping plates 14 are arranged to clamp and fix the workpiece, and under the action of the rubber pad 15, the clamping effect on the workpiece is enhanced, making the clamping limit more stable.
[0032] In this embodiment, a rocker 16 is fixedly connected to one end of the bidirectional screw rod 12 , and a nut 17 is threadedly connected to one side of the outer surface of the bidirectional screw rod 12 .
[0033] During specific use, the rocker 16 is provided to facilitate operation and control of the bidirectional screw 12, and to facilitate hand exertion. The nut 17 locks the bidirectional screw 12 to prevent the bidirectional screw 12 from rotating when not in use.
[0034] In this embodiment, grooves 18 are formed on both sides of the outer surface of the housing 1 , and heat dissipation holes 19 are formed on the inner bottom wall of the grooves 18 .
[0035] During specific use, the heat dissipation holes 19 can dissipate the heat generated by the operation of the refrigerator 3 through the arrangement of the heat dissipation holes 19 .
[0036] In this embodiment, a magnetic ring 20 is magnetically connected to the inner side surface of the groove 18 , and a dustproof net 21 is fixedly connected to the inner side surface of the magnetic ring 20 .
[0037] During specific use, the dustproof net 21 is set inside the groove 18 through the magnetic ring 20, which is easy to install and disassemble, and convenient for cleaning and replacement after long-term use. The dustproof net 21 can block external dust and reduce the entry of external dust.
[0038] In this embodiment, a motor 22 is fixedly connected to the top of the inner side of the housing 1 , a screw rod 23 is fixedly connected to the output end of the motor 22 , and a second slider 24 is threadedly connected to the outer surface of the screw rod 23 .
[0039] During specific use, through the setting of the screw rod 23, the motor 22 drives the screw rod 23 to rotate, so that the second slider 24 on its outer surface drives the slide 25 to move left and right, thereby adjusting the left and right position of the spark machine head 26, which is suitable for processing workpieces of different sizes.
[0040] In this embodiment, a ram 25 is fixedly connected to the upper surface of the second sliding block 24 , and a spark machine head 26 is fixedly connected to the outer surface of the ram 25 .
[0041] When used specifically, by setting the spark machine head 26, the spark machine head 26 is fixed on the outer surface of the slide 25, and the workpiece can be processed by electric sparks, thereby ensuring the high efficiency of the device and the simple structure.
[0042] Working principle: In use, the rocker 16 is used to rotate the bidirectional screw 12, so that the two first sliders 13 are close to each other, and the two clamps 14 clamp and fix the workpiece. Under the action of the rubber pad 15, the clamping effect of the workpiece is strengthened, and the motor 22 drives the screw 23 to rotate, so that the second slider 24 drives the slide 25 to move left and right, and adjusts the left and right position of the spark machine head 26. The spark machine head 26 is fixed on the outer surface of the slide 25, and the workpiece is electrospark machined. The refrigerator 3 is started to cool the coolant, and the delivery pipe 6 transports the cooled coolant to the inside of the serpentine pipe 7 through the water pump 5, so as to quickly cool the working fluid. Moreover, the serpentine pipe 7 is a curved pipe, and the temperature of each point is consistent. While cooling and cooling quickly, the processing quality will not be affected by inconsistent temperature. The reflux pipe 8 transports the coolant after heat exchange back to the lower half of the space inside the shell 1, and then reuses it, so that the coolant keeps circulating. The heat dissipation hole 19 can dissipate the heat generated by the operation of the refrigerator 3, and the dustproof net 21 reduces the entry of external dust.
