[0002] A surface milling cutter is a tool widely used in the field of mechanical processing. It is mainly used for processing surfaces such as planes and inclined surfaces. Due to its simple structure, easy use and high precision, it is widely used in high-end equipment such as CNC machine tools and machining centers.

[0003] In mechanical processing, surface milling cutters can be used for two processing methods: rough machining and fine machining. Rough machining refers to roughly cutting the workpiece surface to remove excess material; fine machining refers to fine cutting of the workpiece surface to obtain a high-precision, high-quality surface.

[0004] At present, when a milling cutter is used for processing, water spraying is usually required for cooling to prevent overheating. However, the current water spraying mostly uses an additional faucet to discharge water or opens a hole on the milling cutter to discharge water directly, and the water output is large and easily causes waste.

[0005] Based on this, the utility model designs an internally cooled four-edge leather milling cutter to solve the above problems. Utility Model Content

[0012] Preferably, the connecting groove is in contact with the water outlet, and the water outlet passes through one end of the milling cutter body.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] During use, the utility model inserts the first magnet into the positioning groove so that the water guide plate is installed, and installs the first magnet and the second magnet on each positioning block so that the water guide plate is kept tilted, and then the water inlet pipe is inserted into the connecting groove for threaded connection, and cold water is injected through the water injection pipe connected to the water inlet pipe, and the cold water is transported from the water outlet to the peripheral chip breaker groove to flush out the waste chips and cool them down. Due to the tilted setting of the water guide plate, the water flow velocity is reduced, and most of the water is blocked by the water guide plate inside the water inlet pipe to cause a certain swirling countercurrent, so that the cold water circulates in the water inlet pipe, which can fully cool the milling cutter body and reduce the waste of water flow while cooling.

Based on the embodiments of 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.

[0022] See also Figure 1-3 The utility model provides a technical solution: an internally cooled four-edged leather milling cutter, comprising a milling cutter body 1, a connecting groove 2 is provided on the side of the milling cutter body 1, a water inlet pipe 3 is connected to the internal thread of the connecting groove 2, a positioning block 4 is fixedly installed on the inner wall of the water inlet pipe 3, a positioning groove 5 is provided on one side of the positioning block 4, a first magnet 6 is magnetically attracted inside the positioning groove 5, a water guide plate 7 is fixedly installed on the side of the first magnet 6, a water outlet 8 is provided at the other end of the milling cutter body 1, and a peripheral chip breaker groove 9 is provided on the outer wall of the milling cutter body 1. In this embodiment, the peripheral chip breaker groove 9 is a V-shaped chip breaker groove, which is a shape in which the cutting edge of the tool is formed into a V-shape. This shape of chip breaker groove is suitable for situations where the chips of the cutting material are easy to discharge. The V-shaped chip breaker groove can guide the chips to both sides of the tool, reduce the interference of chip breaking, and improve the stability and accuracy of cutting.

[0023] Preferably, the inner wall of the connecting groove 2 is threaded, and the outer wall of the water inlet pipe 3 is threaded, and the side area of ​​the water inlet pipe 3 is smaller than the side area of ​​the connecting groove 2. In this embodiment, the threads in the connecting groove 2 and the threads on the outer wall of the water inlet pipe 3 facilitate the connection between the water inlet pipe 3 and the milling cutter body 1, thereby facilitating the transportation of water.

[0024] Preferably, the positioning block 4 is made of metal, and the positioning block 4 can be attracted to the first magnet 6, and the water guide plate 7 and the side of the first magnet 6 are arranged at an angle. In this embodiment, the positioning block 4 and the first magnet 6 are attracted to each other to maintain the stable installation of the water guide plate 7, and the positioning groove 5 and the positioning block 4 are both arranged in a semicircular shape, which can fully prevent the first magnet 6 from falling off and will not be hit by the water flow.

[0025] Preferably, the water inlet pipe 3 is semicircular, the positioning block 4 is semicircular, and the first magnet 6 and the water guide plate 7 are both semicircular. In this embodiment, the semicircular setting of the above structure is convenient for disassembly and assembly of various components and is easy to observe.

[0027] Preferably, the connecting groove 2 is in contact with the water outlet 8, and the water outlet 8 passes through one end of the milling cutter body 1. In this embodiment, the water flow in the water inlet pipe 3 is discharged from the water outlet 8 through the connecting groove 2 and flows to the outer wall of the milling cutter body 1 for cooling and flushing.

[0028] A specific application of this embodiment is:

[0029] Insert the first magnet 6 into the positioning groove 5 so that the water guide plate 7 is installed. Install the first magnet 6 and the second magnet on each positioning block 4 so that the water guide plate 7 remains inclined. Insert the water inlet pipe 3 into the connecting groove 2 for threaded connection. Connect the water injection pipe to the water inlet pipe 3 to inject cold water. The cold water is transported from the water outlet 8 to the peripheral chip breaker groove 9 to flush out the waste chips and cool them down.

[0030] In summary, the structures such as the water inlet pipe 3, the positioning block 4, the positioning groove 5, the first magnet 6 and the water guide plate 7 can fully cool the milling cutter body 1, thereby reducing water waste while cooling it.
