[0002] As the company continues to grow and develop, while pursuing higher quality, it has higher and higher requirements for the production environment. Energy saving, low carbon, and green environmental protection have become the company's higher pursuit of harmonious development. When performing precision turning of aluminum alloy wheels, the tool needs to be cooled to prevent the tool from rapid wear due to high temperature, reduce the possibility of surface deformation of the workpiece caused by high temperature, and reduce friction resistance during cutting.

[0003] Traditional finishing process machine tool processing generally uses cutting fluid to cool the blade. However, the cutting fluid has a strong odor and is easily dirty after long-term circulation, which has a great impact on the on-site environment. In addition, the cutting fluid is irritating to the eyes and skin, and long-term contact with the human body affects health. At the same time, the waste cutting fluid cannot be discharged directly and needs to be centrally processed. In view of the above problems, technicians in this field have proposed a spray device for micro-lubrication cooling in finishing of aluminum alloy wheels to solve the above problems.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 and Figure 3 The utility model provides an embodiment: a spray device for micro-lubrication and cooling of aluminum alloy wheel finishing, comprising an oil storage box 1, a control box 2 is fixedly connected to the top of the oil storage box 1, a solenoid valve 5 is installed on the right side of the outside of the control box 2, the other end of the solenoid valve 5 is fixedly connected to an air pipe 7, the other end of the air pipe 7 is fixedly connected to a nozzle assembly, the nozzle assembly is used to spray lubricating oil, a pneumatic double-joint 3 is fixedly connected to the left side of the top of the oil storage box 1, an air inlet 4 is arranged at the bottom of the pneumatic double-joint 3, a connector 11 is arranged inside the control box 2, a liquid suction pipe 13 is fixedly connected to the bottom end of the connector 11, the other end of the liquid suction pipe 13 extends to the inside of the oil storage box 1 and is fixedly connected to a filter head 14, the other end of the connector 11 is fixedly connected to an oil pipe 10, the other end of the oil pipe 10 is fixedly connected to the outside of the sprayer 9 and extends to the inside of the nozzle 15.

[0023] Specifically, the oil storage box 1 and the control box 2 are connected and fixed to support the control box 2. The control box 2 can be used to control the pneumatic double-joint 3 and the solenoid valve 5, so that after the pneumatic double-joint 3 is started, air will enter through the air inlet 4 for compression, and then be transmitted to the air supply pipe 7 through the air outlet pipe 6, and then be delivered to the nozzle 15. The automatic on and off of the compressed air can be controlled by the solenoid valve 5, so as to facilitate the control of the spray head assembly to spray the lubricating oil. After the compressed air is delivered to the nozzle 15, the cross-section of the nozzle 15 hole becomes smaller, and the gas The pressure decreases accordingly. Since the pressure in the oil storage box 1 is the same as that at the compressed gas inlet, a pressure difference is generated between the gas at the oil storage box 1 and the nozzle 15. The oil pipe 10 and the suction pipe 13 can be connected through the connector 11, so that the lubricating oil in the oil storage box 1 flows into the oil pipe 10. At the same time, the lubricating oil in the oil pipe 10 continuously flows to the nozzle 15 under the push of the compressed gas, and is atomized under the contraction of the nozzle 15 and is ejected at a high speed accompanied by the compressed gas, thereby cooling the tool, improving work efficiency, extending the service life of the tool, and reducing harm to the human body.

[0024] Reference Figure 3 The nozzle assembly includes a sprayer 9, the outside of the sprayer 9 is fixedly connected to the other end of the gas pipe 7, a nozzle 15 is installed on the right side of the sprayer 9, and two adjusting knobs 16 are arranged on the top of the sprayer 9, and the two adjusting knobs 16 respectively control the gas pipe 7 and the oil pipe 10.

[0025] Specifically, the flow rate of the lubricating oil in the oil pipe 10 can be changed by changing the flow regulating knob 16 through the air pipe 7, and the mixing ratio and output size of the trace lubricating oil and compressed air can be adjusted, thereby controlling the amount of lubricating oil sprayed, which can be flexibly adjusted according to actual needs.

[0026] Reference Figure 2 The top of the oil storage box 1 is located on the right side of the control box 2 and is provided with an oil filling port 8. The bottom of the oil filling port 8 is fixedly connected to a filter screen 12. The outer rear side of the pneumatic double-joint 3 is fixedly connected to an air outlet pipe 6. The other end of the air outlet pipe 6 passes through the interior of the control box 2 and is fixedly connected to one end of the solenoid valve 5. One end of the oil delivery pipe 10 passes through the interior of one end of the air delivery pipe 7.

[0027] Specifically, lubricating oil can be added to the oil storage box 1 through the oil filling port 8 to replenish the consumed lubricating oil. At the same time, a filter screen 12 is arranged at the bottom of the oil filling port 8 to prevent foreign matter from entering the oil storage box 1 when adding lubricating oil and causing internal pollution. Compressed air can be transported through the air outlet pipe 6, and the solenoid valve 5 can be used to control the on and off of the compressed air to determine whether cooling is needed according to demand.

[0028] Working principle: When using this device, first add lubricating liquid to the oil storage box 1 through the oil filling port 8, allow air to enter from the air inlet 4 through the pneumatic double-joint 3, and allow the air to enter the air pipe 7 after being compressed by the pneumatic double-joint 3, and then be transported to the nozzle 15. As the cross-section of the nozzle 15 hole becomes smaller, the gas pressure decreases accordingly, and the pressure in the oil storage box 1 is the same as that at the compressed gas inlet, which causes a pressure difference between the gas at the oil storage box 1 and the nozzle 15. The suction pipe 13 is connected to the oil pipe 10 through the connector 11, so that the lubricating oil in the oil storage box 1 flows into the suction pipe 13. At this time, the flow rate of the lubricating oil in the oil pipe 10 can be changed by changing the flow adjustment knob 16. At the same time, the lubricating oil in the suction pipe 13 continuously flows to the nozzle 15 under the push of the compressed gas, is atomized under the contraction of the nozzle 15 and is ejected at high speed accompanied by the compressed gas, thereby cooling the tool, improving work efficiency, extending the service life of the tool, and reducing damage to the human body.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
