Referring to fig. 1, the embodiment discloses a central water outlet tray cutter, which comprises a tray cutter body 1, wherein the tray cutter body 1 comprises a cutter handle 101 and a cutter head 102, the cutter handle 101 is connected with the cutter head 102 and is positioned on a guide surface of the cutter head 102; it should be understood that, due to the limitation of the machining process, that is, the cutter itself needs to rotate at a high speed, the cutter 102 in this embodiment is generally in an approximately cylindrical structure, and the cutter handle 101 is generally disposed coaxially with the cutter 102 on the basis of its guide surface. One end surface of the cutterhead 102 is a guide surface, and the other end surface is a working surface.

The working surface of the cutterhead 102 is provided with a plurality of cutter grains 2, and the cutter grains 2 are distributed circumferentially around the center of the cutterhead 102; it will be appreciated that, due to the limited lifetime of the tool due to the high speed operation of the tool, the need for replacement of the tool insert 2 after a certain period of operation has occurred, and that a separable connection between the tool insert 2 and the cutterhead 102 is typically implemented, for example, by means of a screw connection or the like.

The cutter head 102 is further provided with a flow guiding groove 3, it should be understood that the flow guiding groove 3 may be represented as a flow channel for guiding the cutting fluid, the flow guiding groove 3 extends along the flow guiding surface of the cutter head 102 to the working surface of the cutter head 102, and the outlet of the flow guiding groove 3 faces the cutter particles 2. It can be understood that the cutting fluid input by the external auxiliary structure is input to the guide surface of the cutter head 102, and the cutting fluid can flow to the cutter grains 2 more accurately through the guide of the guide groove 3, so that the cutter grains 2 are cooled, chip removed and lubricated.

In the central water outlet disc cutter in the embodiment, a diversion trench 3 is arranged between the diversion surface and the working surface of the cutter disc 102, so that external cutting fluid can be input from the diversion surface and output to the cutter grain 2 through the guidance of the diversion trench 3. On the one hand, the external auxiliary structure can be arranged above the cutter head 102 to replace the prior art that cutting fluid is input from the side, so that the occupied area of the whole processing equipment can be reduced; on the other hand, due to the diversion effect of the diversion trench 3, the cutting fluid can be more accurately output to the cutter particles 2, so that the cooling effect of the cutter particles 2 is improved, the service life of the cutter particles 2 is prolonged, the cutter particles 2 are lubricated, and the smoothness of a machined workpiece is improved; on the other hand, the weight of the whole central water outlet tray knife is reduced due to the arrangement of the diversion trench 3.

Specifically, referring to fig. 2, in this embodiment, the diversion trench 3 is spirally disposed. The spiral diversion trench 3 can enable the cutting fluid in the diversion trench 3 to flow more smoothly when the cutter rotates. It should be noted that the wall surfaces of the diversion trenches 3 are smooth wall surfaces, so as to improve the fluidity of the cutting fluid.

Specifically, the caliber of the diversion trench 3 gradually decreases from the diversion surface of the cutterhead 102 to the working surface of the cutterhead 102, i.e. the diversion trench 3 has an approximate inverted cone structure. After a certain amount of cutting fluid flows into the diversion trench 3, the pressure is gradually increased along with the gradual reduction of the cross section size of the flow channel (refer to Venturi effect), so that the cutting fluid has a certain pressure when flowing out, and the cooling, chip removing and lubricating effects of the cutting fluid on the cutter particles 2 are improved.

Specifically, referring to fig. 3, a cutting groove 4 is further provided on the cutterhead 102, and the cutting groove 4 is located between the outlet of the diversion trench 3 and the cutter grains 2. It should be understood that, when the cutting grooves 4 are provided, a certain installation space can be provided for the cutter particles 2, so in this embodiment, the cutting grooves 4 are arranged in a one-to-one correspondence with the cutter particles 2. On the other hand, when setting up guiding gutter 3, can make there is certain distance between guiding gutter 3's the export and the cutter grain 2 to make the cutting fluid that flows from guiding gutter 3's export can obtain certain diffusion space, better carries out cooling, lubrication to cutter grain 2. Preferably, in this embodiment, the diversion trenches 3 are disposed in one-to-one correspondence with the knife grains 2. That is, in this embodiment, the diversion trenches 3, the cutting trenches 4 and the cutter grains 2 are in a one-to-one correspondence, and each diversion trench 3, the cutting trench 4 and the cutter grains 2 are a group, and in the whole cutter 102, a plurality of groups are arranged together, and an operator can adjust the number of the groups according to the diameter of the cutter 102, which can be understood that, in order to meet the basic requirement of cutting, the number of the groups is generally not less than 4.

Specifically, referring to fig. 4, a liquid storage cavity 5 is provided on a working surface of the cutterhead 102, and is distributed around the cutter handle 101, and an inlet of the diversion trench 3 is communicated with the liquid storage cavity 5. It should be noted that, since the flow guiding surface of the cutterhead 102 is a plane, there is no storage function, and after the cutting fluid is input to the flow guiding surface of the cutterhead 102, the cutting fluid is limited by the flow guiding capability of the flow guiding groove 3, and part of the cutting fluid overflows from the periphery, and by setting the liquid storage cavity 5, the cutting fluid is firstly stored in the liquid storage cavity 5 after being input, so that a certain buffer space is provided for the flow of the cutting fluid in the flow guiding groove 3. Preferably, the cross section of the liquid storage cavity 5 is elliptical, i.e. approximately annular, and the cutting liquid in the liquid storage cavity 5 can better flow into the diversion trench 3 under the influence of centrifugal force because the cutter is in a high-speed rotation state during operation. It should be understood that the inner wall of the liquid storage chamber 5 in this embodiment is also smooth.

Specifically, the guide surface of the cutterhead 102 is further provided with a guide plate 6, and the guide plate 6 is disposed around the liquid storage cavity 5. It should be understood that, when the cutterhead 102 is in operation, the outer end of the baffle 6 rotates at a higher speed than the inner end, so that the input cutting fluid can be retained in the liquid storage cavity 5 under the action of the baffle 6.

Preferably, the baffle 6 is inclined at a predetermined angle relative to the baffle surface of the cutterhead 102. When the inclination angle of the deflector 6 is too large or too small, the deflector effect is affected to some extent, and in this embodiment, the inclination angle is preferably 20 °, i.e. the angle with the deflector surface is 70 °.

Specifically, referring to fig. 2, in the present embodiment, a plurality of baffles 6 are arranged in a spiral shape. And the rotation direction of the guide plate 6 is the same as that of the guide groove 3. Further, the curvature of the single deflector 6 is the same or substantially the same as the curvature of the single guide groove 3.

In this embodiment, the handle 101 is distributed with a multi-stage stepped structure, so that a certain number of clamping grooves can be formed, which is beneficial to the installation of the tool.
