[0002] As we all know, EDM machine, also known as CNC EDM machine, EDM, spark machine, etc., is a kind of electrical processing equipment. When the Lazarenkos studied the phenomenon and causes of switch contacts being damaged by spark discharge corrosion, they found that the instantaneous high temperature of the electric spark can cause local metal to melt, oxidize and be corroded, thus creating and inventing the EDM processing method. The EDM forming machine needs to be cooled when used for a long time.

[0003] In some traditional or less advanced spark machine cooling devices, there is a disadvantage that it is not convenient to adjust the delivery pipe and the nozzle for height, front and back, and lateral adjustment. If the position of the delivery pipe and the nozzle cannot be accurately adjusted, the oil may not be accurately sprayed to the key area of ​​the spark machine processing part, resulting in limited cooling effect. This may cause the spark machine to have too high a temperature during operation, affecting the processing quality and machine performance. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4A cooling device for a spark machine, comprising a base 1, a machine tool 2, a spark machine body 3, a height adjustment device and a front-and-back adjustment device, wherein a receiving chamber 4 is provided at the top of the base 1, wherein the machine tool 2 is installed in the receiving chamber 4, wherein the spark machine body 3 is installed directly above the base 1 through a support frame, wherein a cooling box 5 is provided at the front end of the base 1, wherein a delivery pipe 6 is provided at the top end of the cooling box 5, wherein a nozzle 7 is provided at the top end of the delivery pipe 6, wherein the front-and-back adjustment device comprises a rectangular groove 8, a first screw 9, a first slider 10 and a first motor 11, wherein the rectangular groove 8 is provided at one side of the top end of the base 1, wherein the first screw 9 is rotatably installed in the rectangular groove 8 Rod 9, one end of the first screw rod 9 passes through the side wall of the base 1 and is installed with the first motor 11, the top of the first screw rod 9 is installed with a fixing ring 12 through the height adjustment device, the height adjustment device includes a rectangular block 13, a groove body 14, a second screw rod 15, a second slider 16 and a second motor 17, the top of the first slider 10 is installed with the rectangular block 13, the end of the rectangular block 13 close to the spark machine body 3 is provided with the groove body 14, the second screw rod 15 is rotatably installed in the groove body 14, the top of the second screw rod 15 passes through the top wall of the rectangular block 13 and is installed with the second motor 17, the second screw rod 15 The second slider 16 is installed on the top, and the fixing ring 12 is installed on the side wall of the second slider 16. The conveying pipe 6 is sleeved in the fixing ring 12. In this embodiment, when in use, when it is necessary to adjust the position of the nozzle 7, the first motor 11 is started, and the first motor 11 drives the first screw 9 to rotate in the rectangular groove 8. Since there is a threaded fit between the first slider 10 and the first screw 9, when the first screw 9 rotates, the first slider 10 moves forward and backward along the rectangular groove 8. Therefore, the forward and backward movement of the first slider 10 drives the fixing ring 12 and the conveying pipe 6 sleeved in the fixing ring 12 to move forward and backward through the height adjustment device, thereby realizing the adjustment of the nozzle 7. The second motor 17 can be used for front and rear adjustment. When the height of the nozzle 7 needs to be adjusted, the second motor 17 is started. The second motor 17 drives the second screw 15 to rotate in the groove body 14. Since there is a threaded fit between the second slider 16 and the second screw 15, when the second screw 15 rotates, the second slider 16 moves up and down along the groove body 14. The up and down movement of the second slider 16 drives the fixing ring 12 and the delivery pipe 6 sleeved in the fixing ring 12 and the nozzle 7 to adjust the height. The oil in the cooling box 5 is transported to the nozzle 7 through the delivery pipe 6 to cool the target position. The nozzle 7 can be fine-tuned through the front and rear adjustment device and the height adjustment device to optimize the cooling effect.

[0027] In actual use, in order to further facilitate the adjustment of the extension length of the nozzle 7, the utility model has the following improvements: an electric telescopic rod 18 is installed on the side wall of one end of the second slider 16 away from the trough body 14, and the output end of the electric telescopic rod 18 is connected to the fixed ring 12. When the electric telescopic rod 18 is started, the extension and contraction of the electric telescopic rod 18 can drive the conveying pipe 6 to adjust the lateral position, which is convenient for adjusting the lateral position of the nozzle 7. This means that the nozzle 7 can be positioned at a specific area that needs to be cooled laterally, thereby improving the cooling effect.

[0028] In actual use, in order to further facilitate the diversion of the oil, in this embodiment, diversion holes 19 are installed around the machine tool 2. The diversion holes 19 facilitate the diversion of the oil flowing out of the nozzle 7 to facilitate the flow into the base 1.

[0029] In actual use, the flexibility of the delivery tube 6 is further improved. In this embodiment, the delivery tube 6 is a telescopic tube. Due to its telescopic characteristics, the telescopic tube can be flexibly adjusted according to different delivery needs and environmental conditions. The telescopic tube can adapt to various complex scenes and meet diverse delivery requirements.

[0030] In actual use, the stability and accuracy of the operation of the first motor 11 and the second motor 17 are further guaranteed. In this embodiment, the first motor 11 and the second motor 17 are servo motors. The servo motors can perform position, speed and torque control with high precision. The servo motors use closed-loop control and have good stability. They can avoid problems such as stalling and vibration, thereby ensuring the stability and accuracy of the operation of the first motor 11 and the second motor 17.

[0031] In actual use, the support stability of the base 1 is further ensured. In this embodiment, support legs 20 are installed at the four corners of the bottom end of the base 1. The four-point support method is symmetrical and therefore has good anti-overturning ability. This means that even under the action of external force, the base 1 can resist the tendency of overturning and maintain its original stable state.

[0032] In actual use, in order to further facilitate the control of the flow rate of the oil, in this embodiment, a pump body 21 is installed at one end of the delivery pipe 6 close to the cooling box 5, and the pump body 21 can facilitate the control of the flow rate and pressure of the oil.

[0033] In actual use, it is further convenient to filter impurities in the oil. In this embodiment, a filter plate 22 is installed on the side wall of the contact surface between the base 1 and the cooling box 5. The filter plate 22 can effectively filter out impurities and pollutants in the oil to ensure the purity of the oil. This can not only reduce the blockage and corrosion of impurities to the inside of the cooling box 5, but also ensure the smooth circulation of the oil, thereby improving the cooling effect.
