[0023] In order to clearly and completely describe the purpose and technical solutions of the present utility model and make the advantages more clearly understood, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0024] Embodiment 1

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution: a corner end mill with a strengthening structure, including: a cutter head 1, a frosted layer 2 is provided on one side surface of the cutter head 1, and a mounting seat 3 is fixedly connected to the other side of the cutter head 1. A lower connecting ring 4 is fixedly sleeved on the outer circumferential surface of the mounting seat 3. An upper connecting ring 5 is arranged above the lower connecting ring 4. A mounting rod 6 is fixedly sleeved inside the upper connecting ring 5. A brake motor 7 is arranged below the mounting rod 6. A turntable 8 is installed below the brake motor 7. Limit rods 9 are arranged around the turntable 8.

[0026] One end of the mounting rod 6 is fixedly sleeved with a connecting seat 15 that abuts against the upper surface of the mounting seat 3. The other end of the mounting rod 6 is fixedly connected to an external driving and rotating device. Through the fixed connection between the lower connecting ring 4 fixedly sleeved on the mounting seat 3 and the upper connecting ring 5 fixedly sleeved on the mounting rod 6, the mounting rod 6 and the mounting seat 3 are initially connected, thereby increasing the installation connection strength between the cutter and the mounting rod 6. A frosted layer 2 is provided on the outer surface of the cutter head 1, which can enhance the working strength of the end mill, improve the overall working efficiency, and at the same time reduce the wear degree of the cutter head 1 during work, and improve the service life of the end mill. Then, by driving the brake motor 7, the brake motor 7 drives the turntable 8 to rotate. The turntable 8 indirectly drives the limit rod 9 to move horizontally, so that the limit rod 9 slides and inserts into the limit hole 11 opened in the mounting seat 3, thereby further increasing the connection fastening strength between the cutter and the mounting rod 6 and ensuring the stability of the cutter head 1 during work. In addition, by reversing the rotation of the brake motor 7 and disassembling the upper connecting ring 5 and the lower connecting ring 4, it is convenient to disassemble and replace the cutter head 1, improving the use effect of the end mill.

[0027] Embodiment 2: On the basis of Embodiment 1, an installation groove 10 is formed on the upper surface of the mounting base 3, and a limiting hole 11 is formed on the side wall of the installation groove 10. The size of the limiting hole 11 is equal to the diameter of the limiting rod 9. The installation groove 10 formed on the upper surface of the mounting base 3 facilitates the fixed installation of the fixing plate 16, and the limiting hole 11 formed on the side wall of the installation groove 10 facilitates the sliding insertion of the limiting rod 9. Connecting holes 12 are formed on the surfaces of both the lower connecting ring 4 and the upper connecting ring 5. A bolt 13 is sleeved in the connecting hole 12, and a nut 14 is threadedly connected to the bottom of the bolt 13. The connecting holes 12 formed on the upper connecting ring 5 and the lower connecting ring 4 are used for the installation of the bolt 13. One end of the bolt 13 is fastened by the nut 14, so that the braking motor 7 is fixedly sleeved in the connecting seat 15. The connecting seat 15 is fixedly sleeved at the bottom of the mounting rod 6. The connecting seat 15 is fixedly installed at the bottom of the mounting rod 6, and the braking motor 7 is limited by the connecting seat 15.

[0028] One side of the connecting seat 15 fixedly sleeved at one end of the mounting rod 6 is abutted against the surface of the mounting base 3, and the other end of the mounting rod 6 is fixedly connected to an external driving and rotating device. By sleeving the bolt 13 in the connecting hole 12 and fastening one end of the bolt 13 with the nut 14, the upper connecting ring 5 and the lower connecting ring 4 are fastened, and further the mounting rod 6 and the tool are fixedly connected, thereby increasing the connection strength between the tool and the mounting rod 6 and ensuring the stability of the tool during operation.

[0029] Embodiment 3: On the basis of Embodiment 2, a fixing plate 16 is slidably connected in the installation groove 10. A limiting block 17 is fixedly connected to the upper surface of the fixing plate 16. A sliding hole 18 is formed on the side wall of the limiting block 17. The upper surface of the limiting block 17 is fixedly connected to the connecting seat 15. The side wall of the fixing plate 16 is slidably connected to the side wall of the installation groove 10, which facilitates the disassembly between the mounting base 3 and the connecting seat 15. The fixing plate 16 and the connecting seat 15 are fixedly connected through the limiting block 17. The sliding hole 18 formed on the side wall of the limiting block 17 limits the limiting rod 9. One side of the limiting rod 9 is slidably connected between the limiting hole 11 and the sliding hole 18, and the other side of the limiting rod 9 is slidably connected to a sliding groove 20 formed on the surface of the turntable 8 through a sliding rod 19. A rotating shaft 21 is fixedly sleeved in the turntable 8. By rotating the turntable 8, the sliding groove 20 formed on the surface of the turntable 8 drives the sliding rod 19 to move. The sliding rod 19 drives one end of the limiting rod 9 to move, and the other end of the sliding rod 19 slides in the limiting hole 11 and the sliding hole 18. A clamping block 22 is fixedly connected to the output end of the braking motor 7, and a clamping groove 23 is formed at the top of the rotating shaft 21. The clamping block 22 and the clamping groove 23 are fixedly connected. The rotating shaft 21 is rotatably sleeved in the fixing plate 16. The clamping block 22 fixedly connected to the output end of the braking motor 7 and the clamping groove 23 formed at the top of the rotating shaft 21 are fixedly connected, which facilitates the clamping block 22 to drive the rotating shaft 21 to rotate through the clamping groove 23, and the fixing plate 16 limits the rotation process of the rotating shaft 21.

[0030] The braking motor 7 is electrically connected to an external terminal control device. When one side of the connecting seat 15 fixedly sleeved at one end of the mounting rod 6 abuts against the surface of the mounting seat 3, by starting the braking motor 7, the braking motor 7 drives the clamping block 22 to rotate. Thus, the clamping block 22 drives the rotating shaft 21 to rotate in the fixing plate 16 through the clamping connection with the clamping groove 23. A turntable 8 is fixedly sleeved on the rotating shaft 21, thereby driving the turntable 8 to rotate. A sliding groove 20 is formed on the surface of the turntable 8, and the sliding groove 20 thus drives the sliding rod 19 to slide therein. Thus, the sliding rod 19 drives one end of the limiting rod 9 to move, and the other end of the limiting rod 9 slides into the limiting hole 11 under the limitation of the sliding hole 18 formed in the limiting block 17. The braking motor 7 stops rotating, and thus the connection between the mounting rod 6 and the mounting seat 3 is further strengthened indirectly under the limiting action of the limiting rod 9, thereby avoiding the loosening between the installation of the tool and the mounting rod 6, and further improving the workpiece processing accuracy and the tool service life. In addition, by reversing the braking motor 7 and removing the bolt 13 installed between the upper connecting ring 5 and the lower connecting ring 4, the milling cutter can be conveniently disassembled and replaced, improving the use effect of the milling cutter.
