[0029] Embodiment 1:

[0030] Please refer to Figures 1-5 The above technical solutions are described in detail through the following embodiments of the utility model.

[0031] A water spraying device for numerical control machine tool machining, comprising:

[0032] Machine tool 1, machine tool 1 includes bed 11, the top surface of bed 11 is provided with a protective device, the rear and bottom of bed 11 are provided with cooling assembly 2.

[0033] The tool holder 13 is slidably installed on the bed 11, and the chip removal groove 12 is arranged below the tool holder 13.

[0034] The chip removal groove 12 is used for receiving the chips generated in the cutting process.

[0035] The protective device includes a protective cover 14, which is fixedly installed on the top surface of the bed 11 by screws, and the protective door 15 is slidably installed on the front side of the protective cover 14, and the bottom of the protective door 15 is slidably connected with the front side of the bed 11.

[0036] The protective door 15 is slidably connected to the protective cover 14 and the bed frame 11 via a known sliding guide rail. The middle part of the protective door 15 is made of transparent glass or resin material, which facilitates observation of the internal processing.

[0037] The cooling assembly 2 includes a circulation assembly connected to a coolant nozzle 27. The circulation assembly is used for circulating the cutting fluid. The coolant nozzle 27 is located inside the protective device and is used to spray out the coolant. The cooling assembly 2 is connected to a cleaning assembly 3.

[0038] The coolant nozzle 27 uses a known universal water spray pipe for lathes with a built-in switch.

[0039] The coolant nozzle 27 is fixedly mounted on the tool holder 13 and the bed frame 11 by a known magnetic spraying method.

[0040] The circulation assembly includes an oil tank 22, a filter disc 21 is snapped onto the front side of the oil tank 22, the filter disc 21 is located directly below the chip removal groove 12, and a cooling pump 23 is provided on the top of the oil tank 22, with the inlet of the cooling pump 23 extending into the oil tank 22.

[0041] The oil tank 22 is inserted into the bottom of the bed frame 11 from the back. The filter plate 21 is used to collect cutting fluid and chips and to filter the cutting fluid. The filtered cutting fluid enters the oil tank 22.

[0042] The bottom of the oil tank 22 can be equipped with casters or other moving devices to facilitate the movement of the oil tank 22 and the cleaning of the filter disc 21.

[0043] The outlet of the cooling pump 23 is connected to a four-way pipe 25 via a first one-way valve 24. The four-way pipe 25 is connected to a second one-way valve 26 and is connected to the coolant spray pipe 27 via a pipeline. The first one-way valve 24 and the second one-way valve 26 only allow substances to flow to the four-way pipe 25.

[0044] When the cooling pump 23 is working, it can pump out the cutting fluid in the oil tank 22, which enters the four-way pipe 25 after passing through the first one-way valve 24, and then is transported to the coolant spray pipe 27 through the pipeline. The coolant is sprayed out by the coolant spray pipe 27 to cool and lubricate the workpiece and the tool.

[0045] The cleaning component 3 includes an air pump 31, which is connected to the circulation component and the protective device via a control line, for cleaning the coolant spray nozzle 27 and the protective device.

[0046] The air pump 31 uses a known air compressor, which can generate compressed air when it is in operation.

[0047] The control pipeline is connected to the air outlet of the air pump 31 via the control valve 32. The control pipeline includes an air filling pipe 33, a first cleaning pipe 34, and a second cleaning pipe 35. The air filling pipe 33 extends into the oil tank 22, and the first cleaning pipe 34 is connected to the second one-way valve 26.

[0048] The control valve 32 is a known electromagnetic valve. There are three control valves 32 in total, one for each of the air supply pipe 33, the first cleaning pipe 34 and the second cleaning pipe 35.

[0049] When the control valve 32 of the air supply pipe 33 is opened, compressed air can enter the oil tank 22, increasing the oxygen content of the cutting fluid.

[0050] When the control valve 32 of the first cleaning pipe 34 is opened, compressed air can enter the four-way pipe 25 from the second one-way valve 26, then press the cutting fluid between the four-way pipe 25 and the cooling fluid spray pipe 27 out of the cooling fluid spray pipe 27, reducing the accumulation of fluid in the pipe. At the same time, the first one-way valve 24 can prevent gas from entering the cooling pump 23. The second one-way valve 26 can prevent the cutting fluid in the four-way pipe 25 from entering the first cleaning pipe 34.

[0051] The cleaning assembly 3 also includes a blowing pipe 36 inserted into the protective door 15 from above, with a nozzle 37 threadedly connected to the side of the blowing pipe 36, facing the inside of the protective door 15, and connected to the second cleaning pipe 35.

[0052] When the control valve 32 of the second cleaning pipe 35 is opened, compressed air enters the blowing pipe 36 and is blown out of the nozzle 37, blowing the cutting fluid or chips splashed on the inside of the protective door 15 away, ensuring a clear view.

[0053] When operating personnel use this device, they close the protective door 15, control the cooling pump 23 to work, and open the cooling fluid spray pipe 27.

[0054] During cutting, the cooling pump 23 pumps the cutting fluid in the oil tank 22 out, through the first one-way valve 24, into the four-way pipe 25, then through the pipe to the cooling fluid spray pipe 27, and is sprayed out of the cooling fluid spray pipe 27 to cool and lubricate the workpiece and tool.

[0055] At the same time, the control valve 32 of the second cleaning pipe 35 is controlled to open, and compressed air is used to blow the cutting fluid or chips splashed on the inside of the protective door 15 away, ensuring a clear view.

[0056] After machining is completed, the control valve 32 of the second cleaning pipe 35 is controlled to close, and then the cooling pump 23 is controlled to stop working.

[0057] Then the control valve 32 of the first cleaning pipe 34 is controlled to open, so that compressed air can enter the four-way pipe 25 from the second one-way valve 26, then press the cutting fluid between the four-way pipe 25 and the cooling fluid spray pipe 27 out of the cooling fluid spray pipe 27, reducing the accumulation of fluid in the pipe.

[0058] When not used for a long time, the control valve 32 of the gas inlet pipe 33 can be controlled to open, so that compressed air can enter the oil tank 22, and the oxygen content of the cutting fluid is improved.

[0059] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application.
