[0017] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0018] See also Figure 1-Figure 2 , Figure 1 This is a schematic diagram of the three-dimensional structure of the processing cooling system provided by the embodiment of the utility model installed on a CNC grinding machine; Figure 2The figure is a schematic diagram of a partially exploded structure of a machining cooling system provided by an embodiment of the present invention installed on a CNC grinding machine. The present invention provides a machining cooling system 1 for a CNC grinding machine, wherein the CNC grinding machine 2 comprises a frame 21, a grinding tool 22 and a support platform 23. The grinding tool 22 is mounted on the frame 21, and the support platform 23 is arranged on one side of the frame 21. A tooling plate 24 for fixing parts is provided on the support platform 23. The grinding tool 22 can grind parts on the tooling plate 24 under the movement of the frame 21. The machining cooling system 1 comprises a cooling box 11, a return box 12 and a cooling pipe 13. One end of the cooling pipe 13 is fixed to the cooling box 11 and communicates with the interior of the cooling box 11, and the other end is connected to the frame 21 and aligned with the grinding tool 22. The cooling box 11 is located on one side of the support platform 23. The return box 12 is arranged above the cooling box 11 and communicates with the cooling box 11 at its bottom. The height of the return box 12 is lower than that of the tooling plate 24.

[0019] One end of the cooling pipe 13 is inserted into the cooling box 11, and the other end corresponds to the position of the grinding tool 22. Therefore, after the cooling liquid is filled in the cooling box 11, the cooling pipe 13 can extract the coolant from the cooling box 11. Then, when the frame 21 drives the grinding tool 22 to grind the parts on the tooling plate 24, the coolant extracted by the cooling pipe 13 can spray the grinding tool 22 for cooling. After passing through the grinding tool 22, the coolant falls onto the surface of the part, thereby achieving the cooling effect on the part, avoiding the temperature of the grinding tool 22 and the part being too high during the grinding process, affecting the accuracy of the part, improving the surface processing quality of the part, and extending the service life of the grinding tool 22.

[0020] By setting the cooling box 11 on one side of the support platform 23 and the return box 12 above the cooling box 11, and the height of the return box 12 is lower than the height of the tooling plate 24, the coolant sprayed by the cooling pipe 13 can flow from the tooling plate 24 into the return box 12. Since the bottom of the return box 12 is connected to the cooling box 11, the coolant in the return box 12 can flow into the cooling box 11, thereby realizing the recycling of the coolant, so that the cooling pipe 13 can extract the coolant in the cooling box 11 to spray cool the mold 22 and parts.

[0021] In an embodiment of the present utility model, the cooling pipe 13 includes a supporting section 131, a connecting section 132 and a spraying section 133. The supporting section 131 is a hard tube and one end is inserted into the cooling box 11, and the other end is connected to the connecting section 132. The connecting section 132 is a hose. The end of the connecting section 132 connected to the spraying section 133 is fixed to the frame 21 through a pipe clamp. The spraying section 133 is a corrugated pipe and the end away from the connecting section 132 is aligned with the mold 22.

[0022] The support section 131 is set as a hard tube and the connecting section 132 is set as a hose, so that one end of the connecting section 132 is inserted into the cooling box 11 and the other end is connected to the connecting section 132, and the other end of the connecting section 132 is fixed to the frame 21 through a pipe clamp, so that the connecting section 132 can be driven to move when the frame 21 moves, and the spray section 133 is connected to the connecting section 132, so that the frame 21 can drive the connecting section 132 to move through the spray section 133 to meet the movement of the frame 21, and at the same time increase the spray range of the spray section 133. By setting the spray section 133 as a bellows, the spray section 133 has a certain hardness, so that the spray angle of the spray section 133 can be adjusted and the spray section 133 after the adjusted angle maintains the current angle to spray the mold 22, thereby improving the spray effect of the spray section 133 on the mold 22, so that the mold 22 can be cooled faster, so that the mold 22 can perform better grinding on the parts.

[0023] In an embodiment of the present utility model, the length of the connecting section 132 is greater than the length of the spraying section 133, so that the connecting section 132 can be driven to move by the spraying section 133 when the frame 21 moves, and the spraying section 133 can be kept connected with the supporting section 131 under the action of the connecting section 132, so as to avoid affecting the normal spraying of the spraying section 133.

[0024] In an embodiment of the present utility model, a nozzle is provided at one end of the spray section 133 close to the mold 22, and the nozzle is threadedly connected to the spray section 133, so that the operator can easily remove the nozzle from the spray pipe and replace a different nozzle connected to the spray section 133 to change the spray pipe to a different spray mode, thereby realizing spraying the mold 22 and parts in different spray modes, thereby improving the spray cooling effect of the mold 22.

[0025] In an embodiment of the present invention, a filter screen is provided at the bottom of the reflux box 12 so that after the coolant on the tooling plate 24 flows into the reflux box 12, the ground parts debris is filtered through the filter screen to prevent the debris from entering the cooling box 11 and causing blockage when the cooling pipe 13 extracts the coolant.

[0026] In an embodiment of the present utility model, a water guide groove 25 is provided on the tooling plate 24, and an open groove is provided on the side of the water guide groove 25 close to the return box 12, and the other side of the water guide groove 25 is closed, so that the coolant can pass through the mold 22 and the parts and fall onto the tooling plate 24, and flow into the water guide groove 25 from the tooling plate 24. Since the water guide groove 25 is provided with an open groove on the side close to the return box 12, the coolant in the water guide groove 25 can flow into the return box 12, and the other side of the water guide groove 25 is closed to prevent the coolant from flowing out from the other end of the water guide groove 25, which makes it impossible for the coolant to reflux.

[0027] In an embodiment of the present invention, the cooling system also includes a water baffle 14, which is fixedly connected to the frame 21 through the rotating shaft of the mold 22. The water baffle 14 is arranged around the mold 22, and a notch 141 is provided on the top of the water baffle 14, and the position of the cooling pipe 13 corresponds to the notch 141.

[0028] By arranging the water baffle 14 around the mold 22 and opening a notch 141 on the top of the water baffle 14, the coolant sprayed by the spray pipe is sprayed toward the mold 22 from the notch 141. When the mold 22 rotates, the coolant is blocked by the water baffle 14 to prevent the coolant from splashing everywhere.

[0029] In an embodiment of the present utility model, a sponge 142 is provided on the surface of the water baffle 14 close to the grinding tool 22, so that after the coolant is sprayed onto the rotating grinding tool 22, the grinding tool 22 will throw the coolant onto the sponge 142 and absorb the coolant under the action of the sponge 142. When the sponge 142 absorbs enough coolant, the coolant slowly drips from the sponge 142, and the dripping coolant falls on the grinding tool 22 to achieve a cooling effect on the grinding tool 22, which facilitates the grinding tool 22 to grind the parts and improves the grinding quality.

Furthermore, when a first feature is "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature.
