[0026] As an embodiment of the utility model, as Figure 1 ,Figure 2 As shown in the figure, the embodiment discloses a tool turret with a cooling mechanism, which is composed of a tool turret shell 1 and a tool disc body 2. The tool turret shell 1 is internally provided with a first cooling channel 20, and the tool disc body 2 is internally provided with a second cooling channel 5. The side of the tool turret shell 1 close to the tool disc body 2 is provided with a connecting piece 3, which can be detachably connected with the tool turret shell 1. Specifically, the connecting piece 3 is connected with the tool turret shell 1 through bolts, so as to facilitate the assembly and disassembly of the whole tool turret. The connecting piece 3 is internally provided with a connecting channel 4, one end of the connecting channel 4 is communicated with the first cooling channel 20, and the other end is communicated with the second cooling channel 5. In this way, the cooling water can flow through the connecting channel 4 from the first cooling channel 20, and finally sprayed out through the second cooling channel 5, so as to realize the cooling effect of the tool. And the first cooling channel 20 is embedded in the inside of the tool turret shell 1, and the connecting piece 3 is located on the side of the tool turret shell 1 close to the tool disc body 2, which effectively saves the space occupied by the whole cooling device, and the first cooling channel 20 can also be used for cooling and cooling of the tool turret shell 1, which is more practical.

[0027] Further, as another embodiment of the utility model: in order to avoid the splashing phenomenon when the cooling water is sprayed through the second cooling channel 5, a mounting groove communicated with the second cooling channel 5 is arranged on the side of the tool disc body 2 away from the tool turret shell 1. The mounting groove is provided with a spray head 6. The spray head 6 is made of rubber material, which effectively prevents the splashing of the cooling water. In order to facilitate the disassembly and replacement of the spray head 6, the side of the tool disc body 2 close to the mounting groove is provided with a limiting device for limiting the movement of the spray head 6. Figure 3 As shown in the figure, the tool disc body 2 of the utility model is provided with a limiting device for preventing the spray head 6 from falling off from the mounting groove. The limiting device includes a limiting screw which can be installed on the tool disc body 2. Under the action of the limiting screw, the spray head 6 can be effectively prevented from falling off from the mounting groove, and by disassembling the limiting screw, the spray head 6 can be conveniently disassembled and replaced.

[0028] Further, as another embodiment of the utility model: as shown in the figure, Figure 4 , Figure 5As shown, in view of the fact that the connecting channel 4 will be connected with different second cooling channels 5 during the rotation of the cutter body 2, in order to enhance the sealing performance between the connecting channel 4 and each second cooling channel 5, a sealing assembly for realizing the communication between the two is arranged inside the connecting piece 3. The sealing assembly comprises a first ring cavity 9, a second ring cavity 8 and a connecting cavity 12 connecting the first ring cavity 9 and the second ring cavity 8 in the connecting piece 3. The connecting cavity 12 adopts an upper and lower structure design, the upper end of which is communicated with the second ring cavity 8, and the lower end of which is communicated with the first ring cavity 9. The first ring cavity 9 is sleeved outside the connecting channel 4, and an inner sleeve 11 is slidably arranged inside the first ring cavity 9. The inner sleeve 11 can move in the first ring cavity 9. The second ring cavity 8 is sleeved outside the first ring cavity 9, and an outer sleeve 10 is slidably arranged inside the second ring cavity 8. The outer sleeve 10 can slide in the second ring cavity 8. Limiting groove structures are arranged in the first ring cavity 9 and the second ring cavity 8 to prevent the outer sleeve 10 and the inner sleeve 11 from disengaging from the connecting piece 3.

[0029] In the connecting cavity 12, a piston rod 13 and a rubber plug 14 are movably mounted at one end close to the outer sleeve 10. One end of the piston rod 13 is connected with the outer sleeve 10, and the other end is connected with the rubber plug 14. At the same time, a sealing plug 15 is movably mounted at one end close to the inner sleeve 11 in the connecting cavity 12, and the sealing plug 15 is also made of rubber. The sealing plug 15 is connected with the inner sleeve 11, and the outer ends of the inner sleeve 11 and the outer sleeve 10 are arranged outside the connecting piece 3. The outer end surface of the inner sleeve 11 is made of elastic material, specifically rubber material. The rubber plug 14 and the sealing plug 15 function to ensure the air tightness of the connecting cavity 12. The outer end surface of the inner sleeve 11 mainly contacts the cutter body 2, and therefore is made of rubber material to ensure the air tightness between the connecting channel 4 and the second cooling channel 5. A return spring 16 connected with the inner sleeve 11 is further arranged in the first ring cavity 9.

[0030] As shown in Figure 6 , Figure 7 , the cutter body 2 is provided with an annular groove 17 on the side close to the cutter tower shell 1, the inlet 19 of the second cooling channel 5 is located in the annular groove 17, the outer sleeve 10 and the inner sleeve 11 can rotate in the annular groove 17, the annular groove 17 is provided with protrusions 18 on both sides of the inlet 19 of the second cooling channel 5, which can abut against the outer sleeve 10, and the protrusions 18 are provided with inclined surfaces on both sides.

[0031] Working principle: in the process of rotating the cutter head body 2, the outer sleeve 10 and the inner sleeve 11 rotate in the annular groove 17 until reaching the inlet 19 of the next second cooling channel 5. The outer sleeve 10 slides along the inclined surface to above the protrusion 18 (the inner sleeve 11 keeps not in contact with the protrusion 18). The protrusion 18 promotes the outer sleeve 10 to move inward in the second annular cavity 8, and drives the piston rod 13 and the rubber plug 14 to move, thereby compressing the air in the connecting cavity 12. The compression force drives the sealing plug 15 and the inner sleeve 11 to move outward in the first annular cavity 9 against the elastic force of the spring, so that the outer end surface of the inner sleeve 11 tightly fits the inlet 19 of the second cooling channel 5, thereby enhancing the air tightness between the connecting channel 4 and the second cooling channel 5. When the cutter head body 2 continues to rotate, the outer sleeve 10 is separated from the protrusion 18, and the inner sleeve 11 is reset under the action of the reset spring 16. The structure design is simple and practical, and occupies less space.

[0032] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
