The utility model achieves the purpose of good cooling effect by providing a water inlet, a drainage hole and a water storage tank. The water storage tank is connected to the outside world through the water inlet, so that the coolant from the outside can flow into the water storage tank for cooling, achieving a good cooling effect. By providing a drainage hole, the milling cutter throws the coolant out of the drainage hole when rotating, which can not only replace the coolant in the inner cavity of the water storage tank, but also facilitate the coolant to flow along the drainage tank to cool the surface of the blade body.

[0004] In the above patent, cooling water is injected into the water inlet, but the amount of cooling water that can enter through the water inlet is small, resulting in a general cooling effect on the inside of the milling cutter. At the same time, in the above patent, when installing the milling cutter, it is fixed by screws, but such installation and subsequent disassembly require the use of corresponding tools, resulting in an increase in the installation or disassembly time of the milling cutter and a reduction in assembly efficiency. Utility Model Content

A screw rod is rotatably provided in the third groove, and the moving block is threadedly arranged on the screw rod.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] 1. In the utility model, the first water inlet and the second water inlet are injected into the cooling groove. At this time, a large amount of coolant can be accumulated in the cooling groove. At the same time, the coolant entering through the inlet during spraying can greatly increase the coolant in the cooling groove, thereby improving the cooling of the milling cutter body. The coolant stored in the second groove is discharged from the gap between the second drain port and the through groove to cool the outer wall of the milling cutter body. Through the above operation, the inner and outer walls of the milling cutter body can be cooled at the same time, thereby improving the cooling effect of the milling cutter body and providing a good working environment for the milling cutter body.

[0020] The water storage sleeve 12 is provided with a water injection pipe 4 at the first groove 14 and the second groove 15. The water injection pipe 4 is used to inject cooling water for cooling the milling cutter body 1. At the same time, in order to prevent water from being thrown out when the milling cutter body 1 rotates, a one-way valve can be set at the water injection pipe 4 to prevent cooling water from being discharged from the water inlet pipe.

[0021] The milling cutter body 1 is provided with an inlet 5 communicating with the cooling groove 18 above the cutter groove. The inlet 5 can inject liquid sprayed externally during machining of the milling cutter body 1 into the cooling groove 18 to cool the interior of the milling cutter body 1 .

[0022] The mounting assembly includes a third groove 2, in which a moving block 22 is slidably provided, and a positioning rod 23 is fixedly provided at the four corners of the moving block 22 facing the mounting groove 111. A positioning groove 24 corresponding to the positioning rod 23 is opened at the top of the milling cutter body 1, and the positioning rod 23 can pass through the third groove 2 and be inserted into the positioning groove 24. A screw 21 is rotatably provided in the third groove 2, and the moving block 22 is threadedly arranged on the screw 21, and the moving block 22 can be driven to move by driving the screw 21 to rotate. At this time, when the moving block 22 moves along the screw 21, the positioning rod 23 on itself will be away from the positioning groove 24 opened on the milling cutter body 1, completing the disassembly between the milling cutter body 1 and the handle 11, and the operation is convenient and no additional tools are needed, which is convenient for the staff to operate. The end of the screw 21 away from the mounting groove 111 passes through the third groove 2 and is fixedly provided with a driving block 25.

[0024] Working principle: In actual use, when the milling cutter body 1 rotates with the processing device, the coolant stored in the water storage jacket 12 will be injected into the cooling groove 18 through the first water inlet 16 and the second water inlet 17 relative to each other. At this time, a large amount of coolant can be accumulated in the cooling groove 18. At the same time, the coolant entering through the inlet 5 during spraying can greatly increase the coolant in the cooling groove 18, thereby improving the cooling of the milling cutter body 1. At the same time, as the milling cutter body 1 rotates, the coolant stored in the second groove 15 is discharged through the gap between the second drain port 19 and the through groove 121, thereby further cooling the outer wall of the milling cutter body 1. Through the above operation, the inner and outer walls of the milling cutter body 1 can be cooled simultaneously, thereby improving the cooling effect of the milling cutter body 1 and providing a good working environment for the milling cutter body 1.

[0025] When the milling cutter body 1 needs to be disassembled, the driving block 25 drives the screw rod 21 to rotate, which can drive the moving block 22 to move. At this time, when the moving block 22 moves along the screw rod 21, the positioning rod 23 on itself will be away from the positioning groove 24 provided on the milling cutter body 1, and the disassembly between the milling cutter body 1 and the shank 11 is completed. The operation is convenient and no additional tools are required, which is convenient for the staff to operate. At the same time, during installation, the top of the milling cutter body 1 is inserted into the installation groove 111 through the through groove 121, and then the milling cutter body 1 can be rotated so that the limiting strip 31 on the protrusion 3 is aligned with the limiting groove 33 on the protrusion 32. At this time, the positioning groove 24 on the milling cutter body 1 and the positioning rod 23 are accurately aligned, which improves the accuracy of installation.
