[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Example
[0019] Please see Figures 1-4 The figure shows a high-efficiency ball end mill, including a milling cutter body 1, a support frame one 10, a support frame two 11, and a heat conduction component and a cooling component. The heat conduction component is installed inside the milling cutter body 1, and the cooling component is installed between the support frame one 10 and the support frame two 11. When the cooling component is activated, it conducts heat out of the inside of the milling cutter body 1.
[0020] Based on the aforementioned scheme, the cooling assembly includes a circulation pipe 13, and the second support frame 11 has a circulation pipe 13 inside, with a portion of the circulation pipe 13 exposed outside the second support frame 11. The cooling assembly also includes a water tank 8, hoses 9, and a semiconductor cooling chip 14. The first support frame 10 is externally fixedly connected to the water tank 8, and the water tank 8 is connected to both ends of the circulation pipe 13 through two sets of hoses 9. The output end of the micro pump inside the water tank 8 is connected to the hoses 9, and the surface of the water tank 8 is equipped with a semiconductor cooling chip 14.
[0021] Furthermore, both the first support frame 10 and the second support frame 11 are provided with two symmetrical rubber pads 12 on their inner walls, and the first support frame 10 and the second support frame 11 are detachably connected by screws and bolts.
[0022] Symmetrical support frames 10 and 11 are provided on the surface of the milling cutter body 1. A micro pump in the water tank 8 outside the support frame 10 draws cooling water through a hose 9 into the circulation pipe 13 inside the support frame 11. The circulation pipe 13 is located on the same horizontal plane as the heat-conducting plate 7, which dissipates the heat accumulated inside the heat-conducting plate 7. The cooling water in the water tank 8 is continuously cooled by the semiconductor cooling chip 14 on the surface of the water tank 8, ensuring the cooling of the heat-conducting plate 7 and the heat-conducting rod 3, and thus cooling down the milling cutter body 1, ensuring the working efficiency of the milling cutter body 1.
[0023] As a further improvement of this invention, the heat-conducting assembly includes a heat-conducting rod 3, a slot 6, and a heat-conducting sheet 7. The surface of the milling cutter body 1 has equidistant slots 6, and the heat-conducting sheet 7 is engaged inside the slots 6. The top of the milling cutter body 1 is detachably connected to the heat-conducting rod 3, and the heat-conducting rod 3 passes through the equidistant heat-conducting sheet 7. The heat-conducting assembly also includes a threaded head 2, a threaded groove 4, and a round hole 5. The top of the heat-conducting rod 3 is fixedly connected to the threaded head 2, and the threaded head 2 is engaged with the threaded groove 4 on the top of the milling cutter body 1. The top of the milling cutter body 1 is also provided with a matching round hole 5 at the bottom of the threaded groove 4. The heat-conducting rod 3 and the heat-conducting sheet 7 are made of the same material, and the heat conduction performance of the heat-conducting rod 3 and the heat-conducting sheet 7 is better than that of the milling cutter body 1.
[0024] A heat-conducting plate 7 is installed in equidistant slots 6 on the surface of the milling cutter body 1. A heat-conducting rod 3 is inserted into the top of the milling cutter body 1, and the heat-conducting rod 3 passes through the heat-conducting plate 7. The heat-conducting rod 3 and the heat-conducting plate 7 are made of the same material and have better thermal conductivity than the milling cutter body 1. The heat generated when the milling cutter body 1 is drilling is transferred to the heat-conducting rod 3 and the heat-conducting plate 4, which can prevent the drill bit position of the milling cutter body 1 from overheating and ensure the processing efficiency of the milling cutter body 1.
[0025] It should be noted that this utility model is a high-efficiency ball end mill. Before installing the end mill body 1, the support frame 10 and the support frame 2 11 are fixed to the surface of the end mill body 1 using matching screws and bolts. Then, the end mill body 1 is installed for drilling operations. During the drilling operation, the temperature inside the end mill body 1 gradually increases due to friction. The heat inside the end mill body 1 is transferred to the heat-conducting rod 3 and the heat-conducting plate 7 to prevent the drill bit position of the end mill body 1 from overheating. Cooling water is drawn into the support frame 2 11 through the hose 9 by the micro pump in the water tank 8 outside the support frame 10. Inside the circulation pipe 13 (the circulation pipe 13 and the heat-conducting plate 7 are located on the same horizontal plane), the heat accumulated inside the heat-conducting plate 7 is discharged. Under the action of the semiconductor cooling plate 14 on the surface of the water tank 8 (the cold end of the semiconductor cooling plate 14 contacts the cooling water inside the water tank 8 to achieve a cooling effect, and its hot end is located outside the water tank 8, and the heat of the hot end is dissipated into the air during the processing operation), the cooling water in the water tank 8 is continuously cooled. Then, the cooling water circulation cools the heat-conducting plate 7 and the heat-conducting rod 3, and the end mill body 1 is cooled to ensure the working efficiency of the end mill body 1.
