[0002] The high-efficiency milling processing device for the heat dissipation fins of the high-voltage distribution box is a CNC machine tool equipment specially used for processing heat dissipation fins. It aims to improve the processing efficiency and precision of the heat dissipation fins. The device uses high-speed milling to cut aluminum blocks or copper blocks into fins with fine heat dissipation structures, thereby increasing the heat dissipation area and improving the heat dissipation performance of the high-voltage distribution box. Its working principle is to use a high-speed rotating milling cutter to perform precision cutting on metal materials. At the same time, it is equipped with an automatic clamping mechanism to ensure processing stability, and the coolant system is used to reduce the tool temperature, reduce thermal deformation, and increase tool life. The device is suitable for mass production and is widely used in power equipment, industrial control, new energy vehicles and other fields. By optimizing the tool path and intelligent feed control, the processing efficiency is improved, the quality and consistency of the heat dissipation fins are guaranteed, thereby improving the overall heat dissipation effect and working stability of the high-voltage distribution box.

[0003] In the prior art, when machine tools process heat sink fins, most devices adopt a single processing method in which the scraper moves and the processing table is fixed, or the processing table moves and the scraper is fixed, to cut aluminum blocks or copper blocks. However, this processing method has the problem of low efficiency during long-term operation, which leads to extended processing cycle and affects production efficiency. Therefore, it is urgent to develop a processing method in which the processing table and the scraper work synchronously and cooperatively. Through the coordinated movement of the two, the cutting efficiency is improved, the processing time is reduced, thereby improving the overall production capacity and equipment utilization.

[0036] The working principle of the present invention is as follows: when in use, the power is turned on, and after the equipment is started, the suction cup 205 uses an electric vacuum system to vacuum adsorb and fix the aluminum block or copper block. The adsorption force generated by the suction cup 205 ensures the stability of the workpiece, and provides additional mechanical support through the support rod 206 to prevent the displacement or deformation of the workpiece due to the cutting force during the processing, thereby improving the processing accuracy. The bottom of the suction cup 205 is provided with a water outlet 207 and a water filter trough 208 to ensure that the coolant generated during the processing can be effectively discharged to prevent the accumulation of liquid from affecting the processing stability; At the beginning of the processing, the first motor 6 is started to drive the rotating shaft 7 to rotate, and the rotating shaft 7 drives the gear 8 to rotate. The gear 8 pushes the rack 10 to move laterally through meshing, thereby driving the scraper 5 to move laterally along the fourth slide groove 17 to perform precise milling on the workpiece fixed on the suction cup 205; At the same time, the second motor 11 is started, driving the screw 12 to rotate, so that the sliding block 202 slides along the first slide groove 2031 at the bottom end of the bottom box 203, so that the workbench 2 moves smoothly along the second guide rod 22 to realize the feeding movement of the workpiece. During the whole processing process, the control panel 24 accurately controls the forward and reverse rotation of the first motor 6 and the second motor 11, so that the scraper 5 and the workbench 2 move synchronously and coordinately to ensure the accuracy of the cutting trajectory; In order to ensure the stability and safety of cutting, the limit frame 16, the limit rod 18, the limit block 20 and the limit plate 21 work together to restrict the movement range of the scraper 5 and the workbench 2, prevent errors or equipment damage, and improve the overall processing accuracy; During the cutting process, the circulation component 4 automatically starts, the water pump 403 draws coolant from the water tank 401, and delivers it to the nozzle 407 through the water hose 405. The nozzle 407 evenly sprays the coolant to the processing area, effectively reducing the temperature of the scraper 5 and the workpiece, reducing the heat accumulation during the cutting process, and preventing tool wear or reduced processing accuracy caused by overheating. At the same time, the coolant can reduce the impact of metal debris generated by cutting on the tool and the processing surface, improve the processing surface quality, and extend the tool life; During the reciprocating motion, the suction cup 205 guides the coolant to flush along the workpiece surface and the guide lines of the equipment, ensuring continuous cooling of the processing area and cleaning chips and impurities. The flushed coolant flows into the water filter tank 208 and enters the bottom box 203 through the water inlet hose 402, and is then transported to the water tank 401 by the circulation component 4 for filtration and reuse, thereby improving cooling efficiency, reducing coolant waste, and reducing operating costs. After the processing is completed, the control panel 24 stops the operation of the first motor 6 and the second motor 11, and releases the suction cup 205 to loosen the workpiece, and the operator can take out the processed heat sink fins for inspection and subsequent processing; The present invention optimizes the cutting method and improves the processing accuracy and efficiency of the heat sink fins through the synchronous coordinated movement of the processing table and the scraper 5. At the same time, the circulating cooling system 4 ensures that the processing area maintains an optimal temperature, reduces tool wear, and improves processing quality.
