DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1

[0027] The drilling diameter adjustment component 5 includes an adjustment block 502, which is rotatably installed on one side of the milling cutter body 1. One end of the adjustment block 502 is fixedly connected to a first bevel gear 503 through a rotating shaft, and the bottom of the first bevel gear 503 is meshed with a second bevel gear 504. The bottom of the second bevel gear 504 is fixedly connected to a screw rod 505, and the outside of the screw rod 505 is connected to a drill bit 501 through a thread. This arrangement improves the situation in actual use. Different sizes of holes and grooves may need to be opened on the same milling plane, or the milling cutter may need to be replaced to expand the milling range, which increases the repositioning time and the tool changing time. The operator may make a location error during the calibration process, which not only seriously affects the processing efficiency, but also may cause the processing error to be too large and the assembly cannot be performed. Embodiment 2

[0028] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0029] The rapid cooling component 4 includes a coolant storage tank 403, which is opened inside the milling cutter body 1. One side of the coolant storage tank 403 is connected to a liquid inlet 404. The coolant is input into the coolant storage tank 403 and the drain pipe 402 by using the liquid inlet 404 and an external water pump, and then flows out from the drain port 401.

[0030] Four groups of drainage pipes 402 are connected to the bottom of the coolant storage tank 403. The drainage pipes 402 adopt a completely straight extension design structure. On the one hand, it is conducive to the reasonable manufacture of the milling cutter body 1. On the other hand, the continuous straight drainage pipes 402 also have the advantage of small flow resistance; drainage ports 401 are provided at the ends of the four groups of drainage pipes 402. This setting can realize the cooling of the milling cutter edge 2, and improves the problem that the temperature of the drill bit 501 is high and cannot be quickly dissipated when the milling cutter edge 2 is working, resulting in the milling cutter edge 2 being easily worn and having a short service life during use. Embodiment 3

[0031] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0032] A milling cutter edge 2 is arranged at the bottom of the milling cutter body 1, and the milling cutter edge 2 and the milling cutter body 1 are an integrally formed structure; a chip groove 3 is opened on the surface of the milling cutter edge 2, and the chip groove 3 can be used for chip removal; a drain port 401 is located at the top of the chip groove 3, and the coolant flows out through the drain port 401 to quickly flush the surface of the milling cutter edge 2 and the chip groove 3.

[0033] The milling cutter material composition structure 6 includes a silicone heat-resistant layer 601, a tungsten carbide reinforced nickel-based alloy wear-resistant layer 602 is arranged inside the silicone heat-resistant layer 601, a nano-diamond reinforcement layer 603 is arranged inside the tungsten carbide reinforced nickel-based alloy wear-resistant layer 602, and a cemented carbide base layer 604 is arranged inside the nano-diamond reinforcement layer 603; through the setting of the milling cutter material composition structure 6, in which the silicone heat-resistant layer 601 is matched with the tungsten carbide reinforced nickel-based alloy wear-resistant layer 602 and the nano-diamond reinforcement layer 603 and the cemented carbide base layer 604, the milling cutter body 1 and the milling cutter edge 2 have a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, etc., which ensures the long life of the milling cutter body 1 and the milling cutter edge 2, and is very practical.

[0034] Working principle: When using the four-edge end mill with rapid cooling function, the rapid cooling component 4 is set up, and the coolant is input into the coolant storage tank 403 and the discharge pipe 402 by using the liquid inlet 404 and the external water pump, and then flows out from the discharge port 401. The design structure in which the four groups of discharge pipes 402 extend completely in a straight line is conducive to the reasonable manufacture of the milling cutter body 1 on the one hand, and the continuous straight discharge pipe 402 also has the advantage of small flow resistance on the other hand. This setting can quickly flush the surface of the milling cutter edge 2 and the chip groove 3, and cool the milling cutter edge 2 by flowing coolant, thereby improving the problem that the temperature of the drill bit 501 of the milling cutter edge 2 is high and cannot dissipate heat quickly when the milling cutter edge 2 is working, resulting in the milling cutter edge 2 being easy to wear and having a short service life during use; through the provided drilling diameter adjustment component 5, when in use, the rotating adjustment block 502 drives the first bevel gear 503 to rotate, and the milling cutter edge 2 is rotated. The screw rod 505 is driven to rotate, so that the drill bit 501 extends out of the inside of the milling cutter edge 2 to adjust the size of the hole groove, which improves the situation that in actual use, holes of different sizes may need to be opened on the same milling plane, or the milling cutter needs to be replaced to expand the milling range, which increases the repositioning time and the tool change time. The operator may make a site error during the calibration process, which not only seriously affects the processing efficiency, but also may cause the processing error to be too large and the assembly cannot be performed. The milling cutter material composition structure 6 is set, in which the silicone heat-resistant layer 601 is matched with the tungsten carbide reinforced nickel-based alloy wear-resistant layer 602 and the nano-diamond reinforcement layer 603 and the cemented carbide base layer 604, so that the milling cutter body 1 and the milling cutter edge 2 have a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, etc., which ensures the long life of the milling cutter body 1 and the milling cutter edge 2, which is very practical.
