[0032] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present invention can be more thoroughly understood and the scope of the present invention can be completely conveyed to those skilled in the art.

[0033] As Figures 1 to 5 shown, an embodiment of the present invention provides a metal end mill 2 facilitating blade replacement, including a mounting member 1 and an end mill 2 mounted on the mounting member 1. A replacement mechanism for replacing different end mills 2 is connected to the end mill 2. Among them, the replacement device 3 includes a mounting groove 31 provided on the milling head, and a circular block 38 having the same size as the mounting groove 31 is provided at the top end of the end mill 2. The end mill 2 and the circular block 38 are of an integral structure. Four rectangular blocks 33 are integrally provided on the circular block 38. The four rectangular blocks 33 are grouped in pairs. Clamping blocks 34 are provided in the inner walls of one of the two groups of rectangular blocks 33. Rectangular holes 32 having the same size as the clamping blocks 34 are provided on the inner wall of the mounting groove 31. A spring member is provided at the bottom of the clamping block 34 and connected to the rectangular block 33.

[0034] It should be supplemented that, as Figure 4 shown, the spring member includes a spring 36. The two ends of the spring 36 are respectively fixedly connected to the bottom wall of the rectangular block 33 and the clamping block 34. Two connecting rods 37 are symmetrically and fixedly connected to the bottom of the clamping block 34. The connecting rods 37 are slidably connected to the surface of the circular block 38. When the clamping block 34 moves, the connecting rods 37 will limit the clamping block 34, and at the same time, the spring 36 will reset the clamping block 34. When the clamping block 34 cooperates with the rectangular hole 32, the milling head on the circular block 38 can be clamped, and thus the replacement of end mills 2 of different sizes can be completed.

[0035] It is further explained that one end of the clamping block 34 is provided with a pressing block 35 of an integral structure, and the pressing block 35 is movably connected to one side of the rectangular block 33. Through the setting of the pressing block 35, the clamping block 34 can move in the inner wall of the rectangular block 33, so as to realize the separation and clamping between the clamping block 34 and the rectangular hole 32.

[0036] At the same time, in order to prevent the clamping block 34 from detaching from the rectangular block 33, as Figure 4 shown, the bottom cross-section of the clamping block 34 is rectangular, and rectangular protrusions are provided on both opposite sides of the bottom of the clamping block 34 extending outward.

[0037] As Figure 1 and Figure 5As shown in the figure, a cooling device 4 for cooling the milling cutter 2 is provided on the mounting member 1. The cooling device 4 includes a water storage member provided on the mounting member 1 and a water delivery assembly for spraying water on the water storage member. The water storage member includes a water storage cylinder 41 with a hollow structure provided on the mounting member 1 and a water inlet pipe 43 provided on the mounting member 1. A booster pump 42 is provided at the top of the water storage cylinder 41. The booster pump 42 can pressurize the inside of the water storage cylinder 41 to achieve high-speed spraying of water flow. The water delivery assembly includes four water outlet pipes 44 provided on the water storage cylinder 41 and a flushing pipe 45 connected to the water outlet pipe 44.

[0038] In order to be able to hang the flushing pipe 45, as Figure 5 shown, a receiving frame 46 is fixedly connected to the bottom of the mounting member 1. Four rotating frames 47 are fixedly connected to the receiving frame 46. The flushing pipe 45 is clamped inside the inner wall of the rotating frame 47. At the same time, the flushing pipe 45 and the rotating frame 47 can be disassembled. A knob 48 is installed on one side of the rotating frame 47. The knob 48 cooperates with the rotating frame 47 to limit the angle of the flushing pipe 45.

[0039] In the embodiment of the present utility model (working principle), when the blade needs to be replaced, the user only needs to operate the pressing block 35 to trigger the spring 36 mechanism, so that the clamping block 34 is separated from the rectangular hole 32 in the installation groove 31, thereby releasing the milling cutter 2. After replacing the new blade, the clamping block 34 automatically resets under the action of the spring 36 force and tightly fits into the installation groove 31 to ensure that the blade is firmly fixed in place.

[0040] At the same time, in order to reduce the temperature of the milling cutter 2 during the milling process, a cooling device 4 is equipped on the mounting member 1. The water storage cylinder 41 is filled with water through the water inlet pipe 43 and pressurized by the booster pump 42. The water flow is sprayed out through the water outlet pipe 44 in the water delivery assembly and directly cools the milling cutter 2, thereby improving the heat dissipation efficiency of the milling cutter 2 and extending its service life. The hanging design of the flushing pipe 45 allows the user to adjust the spraying angle of the water flow according to the specific requirements of the milling operation. By operating the knob 48, the user can easily achieve precise control of the spraying direction of the flushing pipe 45 to adapt to different milling conditions.

[0041] The above is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle described in the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
