Especially in areas where water resources are relatively scarce or water prices are high, this impact is more obvious. In addition to water usage costs, a large amount of water consumption also means an increase in sewage treatment costs. Especially in areas where strict emission standards need to be met, the sewage treatment cost may be even higher, increasing the operating cost of the enterprise.

Detailed implementation manners

[0021] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention, and cannot be used to limit the protection scope of the present invention.

[0022] The present invention provides a water-cooling device for machine tool processing as shown in Figures 1-4 Figure 10, which includes a machine tool body 1 and a machine tool spindle 4. A plurality of atomizing nozzles 15 are detachably installed at the bottom end of the machine tool spindle 4. The plurality of atomizing nozzles 15 are commonly connected to an annular connecting plate 17. One end of the annular connecting plate 17 is connected to a pipeline 6 for conveying a cooling liquid. An induction sensor 3 for controlling the on-off of the atomizing nozzles 15 is arranged on the outer side of the machine tool body 1. The inside of the annular connecting plate 17 is communicated with each atomizing nozzle 15 to ensure that the cooling liquid can be evenly sprayed out by the plurality of atomizing nozzles 15.

[0023] A water-cooled storage space 7 is arranged inside the machine tool body 1. A water storage tank 8 for storing a cooling liquid is arranged inside the water-cooled storage space 7. A compressed gas cylinder 9 is also arranged inside the water-cooled storage space 7. By mixing the cooling liquid with air, high-speed water mist is produced, so as to achieve the purpose of better water-cooling and temperature reduction.

[0024] The water storage tank 8 is filled with a cooling liquid. One end of the water storage tank 8 is connected to a tee 14 through a pipeline 6. An adjusting gear 12 for adjusting the flow rate of the cooling liquid is arranged at the connection end of the pipeline 6 of the tee 14 and the water storage tank 8. By controlling the flow rate of the cooling liquid, it is avoided that the liquid ratio is too high and the air is not enough to fully disperse the water droplets, which may cause the water mist particles to be larger and not fine enough, affecting the cooling effect.

[0025] One end of the compressed gas cylinder 9 is connected to a pressure pump 10 through a pipeline 6. The pipeline 6 is connected to the other end of the tee 14 through the pressure pump 10. An adjusting gear 12 for adjusting the gas flow rate is arranged at the connection end of the pipeline 6 of the tee 14 and the compressed gas cylinder 9. By controlling the flow rate of the gas, it is avoided that due to too high an air ratio, the water mist may be too dispersed, which will instead reduce the effective range and the heat dissipation efficiency.

[0026] The tee 14 is installed on the support frame. One side of the tee 14 is provided with a driving gear 11 for controlling the rotation of the adjusting gear 12. The pipeline 6 where the output end of the tee 14 is located is communicated with the annular connecting plate 17. An electromagnetic closing valve 13 for closing the coolant flow is arranged at the output end of the tee 14. By controlling the rotation of different driving gears 11 through the control panel 2, the intelligent control of the high-speed water mist is realized, ensuring the best working effect for a long time.

[0027] A plurality of the atomizing nozzles 15 are installed at one end of the nozzle mounting plate 5. Connecting rods 16 are arranged at multiple corners of the nozzle mounting plate 5. The nozzle mounting plate 5 is installed at the bottom end of the machine tool spindle 4 through the connecting rods 16. Through the arrangement of the nozzle mounting plate 5, the spraying directions of the plurality of atomizing nozzles 15 are effectively fixed, the control difficulty is reduced, and the working platform and the workpiece are ensured to be cooled evenly and comprehensively.

[0028] A control panel 2 is further arranged on the outer side of the machine tool body 1. The control panel 2 can be used to control the rotation of a plurality of driving gears 11 and to control the closing of the electromagnetic closing valve 13 after receiving the output signal of the induction sensor 3. The induction sensor 3 is arranged at the hatch of the machine tool body 1. When it is detected that the hatch is opened, the electromagnetic closing valve 13 is controlled to close to prevent the large water mist from splashing onto the staff.

[0029] In this utility model, by installing a plurality of atomizing nozzles 15 at the bottom end of the machine tool spindle 4, the purpose of cooling the workpiece is achieved. By controlling the rotation of the adjusting gear 12 through the driving gear 11, the flow rates of the coolant and the high-pressure gas are controlled, and the high-speed water mist is used to cool the workpiece. Due to the small and numerous water mist particles, the high-speed water mist has a fast evaporation speed and a wide coverage range. Therefore, it can cover the heat dissipation surface more widely, improve the heat dissipation efficiency. At the same time, compared with direct water flow, the amount of water required for the evaporation of the water mist is less, which helps to save water resources. The atomizing nozzles 15 are annularly arranged outside the tool, which can ensure the cooling effect on the workpiece and the tool.

[0030] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present utility model.
