Description

Technical Field

[0001] This utility model relates to the field of lubrication device technology, and in particular to an oil mist cooling lubrication device. Background Technology

[0002] Oil mist cooling and lubrication devices are used in fields such as machining. They convert lubricating oil into tiny oil mist particles and precisely deliver these particles to the parts requiring cooling and lubrication. The basic principle is to use a special atomizing device, with compressed air or other power sources, to break down liquid lubricating oil into tiny droplets, forming an oil mist. This oil mist can diffuse like a gas around the processing area or critical components of the equipment. Currently, oil mist cooling and lubrication devices primarily regulate the amount of oil mist used based on airflow. When the pressure and flow rate of compressed air increase, the amount of oil drawn into the oil pipe increases due to the Venturi effect, and consequently, the amount of oil atomized also increases.

[0003] In scenarios where oil consumption needs to be reduced, such as when cooling and lubricating small cutting tools, the flow rate of compressed air is often reduced to decrease the amount of atomized oil in order to avoid wasting lubricating oil. However, due to insufficient kinetic energy, the low-flow-rate oil mist is unable to break through the airflow barrier formed by the high-speed rotation of the small cutting tool and cannot fully contact the tool surface. This results in a significant reduction in the cooling and lubrication effect of the tool during operation, which not only affects the tool life but may also have an adverse effect on machining accuracy. Therefore, an oil mist cooling and lubrication device is proposed. Utility Model Content

[0028] Example

[0029] Reference Figure 1-Figure 5 As an embodiment of the present invention, an oil mist cooling and lubrication device is provided, comprising: a conveying unit 100 and an atomizing unit 200;

[0030] The conveying unit 100 includes an oil drum 101. An oil filling pipe 102 is fixedly connected to the side wall of the oil drum 101. An oil suction pipe 103 is fixedly connected to the bottom of the oil drum 101. An air inlet pipe 104 is fixedly connected to the top of the oil drum 101. Valves are fitted on the outer walls of both the air inlet pipe 104 and the oil suction pipe 103. An air delivery pipe 105 is fixedly connected to the top of the air inlet pipe 104. An oil supply pipe 106 is fixedly connected to one end of the oil suction pipe 103 near the air delivery pipe 105. The oil supply pipe 106 extends into the interior of the air delivery pipe 105.

[0031] The atomizing unit 200 includes a conical cover 201 fixedly connected to one end of the air supply pipe 105. A circular box 202 is fixedly connected to the end of the conical cover 201. A conical tube 203 is fixedly connected to one side of the circular box 202. An atomizing tube 204 is fixedly connected to one end of the conical tube 203. The atomizing unit 200 also includes an adjustment component 205 fixedly used to adjust the size of the atomized particles.

[0032] Specifically, the adjustment component 205 includes a handle 2051 rotatably connected to one side of the circular box 202. One end of the handle 2051 passes through the circular box 202 and is fixedly connected to a turntable 2052. One side of the turntable 2052 is fixedly connected to multiple adjustment tubes 2053 that pass through the turntable 2052. The multiple adjustment tubes 2053 have the same diameter, and the inner diameter of the multiple adjustment tubes 2053 decreases sequentially.

[0033] The top of the refueling pipe 102 is equipped with a removable sealing cap. The refueling pipe 102 is used to add oil to the oil drum 101. The end of the gas supply pipe 105 away from the conical shroud 201 is connected to an external air pump, which allows high-speed gas to flow in the gas supply pipe 105. Some of the gas in the gas supply pipe 105 enters the oil drum 101 through the air inlet pipe 104, increasing the internal pressure of the oil drum 101 and causing the oil to flow upwards through the oil suction pipe 103. The liquid in the oil suction pipe 103 is then transported to the oil supply pipe 106. Inside the air pipe 105, the oil supply pipe 106 is arranged in an L-shape, and the lateral end of the oil supply pipe 106 is aligned with the airflow direction to prevent air from entering the oil supply pipe 106. The air intake of the air intake pipe 104 can be adjusted by the valve of the air intake pipe 104 to regulate the pressure inside the oil tank 101. The higher the pressure, the more the oil suction pipe 103 draws in, and the lower the pressure, the less it draws in. The valve of the oil suction pipe 103 is used to adjust the oil supply of the oil supply pipe 106 so as to adjust it according to the size of the cutting tool.

[0034] This allows for a reduction in oil supply without decreasing the airflow velocity in the air supply pipe 105, enabling a small amount of oil mist to contact the high-speed rotating cutting tool. After the air comes into contact with the oil, the air will carry the oil through the conical cover 201. The conical cover 201 and the conical tube 203 are connected by at least one regulating pipe 2053, forming a Venturi effect between the conical cover 201, the regulating pipe 2053, and the conical tube 203, thereby breaking the oil into tiny oil droplets and forming oil mist. The oil mist is then discharged through the atomizing pipe 204. The throttle 2051 can drive the turntable 2052 to rotate. The turntable 2052 has four regulating pipes 2053 of the same diameter. Each regulating pipe 2053 can be connected to the conical cover 201 and the conical tube 203. The four regulating pipes 2053 are distributed in a ring at equal intervals, and the inner diameters of the four regulating pipes 2053 decrease in that order.

[0035] When the regulating pipe 2053 with the largest inner diameter is connected to the conical cover 201 and the conical tube 203, air and oil can quickly pass through the regulating pipe 2053, reducing its contraction pressure and forming large oil mist particles. The thick lubricating film formed by the large oil mist particles can better withstand heavy load pressure. When the regulating pipe 2053 with the smallest inner diameter is connected to the conical cover 201 and the conical tube 203, air and oil have difficulty quickly passing through the regulating pipe 2053, increasing its contraction pressure and forming small oil mist particles. This provides precise lubrication in the small space of precision equipment. Different inner diameter regulating pipes 2053 can form oil mist particles of different sizes, so as to provide the appropriate oil mist for different types of devices and give full play to the cooling and lubrication effects of the oil mist.

[0036] In addition, a threaded plug 206 is threaded through the throttle 2051 on one side, and multiple internal threaded sleeves 207 that fit the threaded plug 206 are fixedly connected to one side of the circular box 202.

[0037] There are four internal threaded sleeves 207. The four internal threaded sleeves 207 are aligned with the four adjusting tubes 2053. When one of the adjusting tubes 2053 is connected to the conical cover 201 and the conical tube 203, the threaded bolt 206 is rotated to make it threaded into the corresponding internal threaded sleeve 207. This fixes the position of the adjusting tube 2053 and makes it securely connected to the conical cover 201 and the conical tube 203.

[0038] Furthermore, each internal threaded sleeve 207 has a circular piece 208 fixedly fitted onto its outer wall, and the diameters of the multiple circular pieces 208 decrease sequentially.

[0039] Starting with the adjusting tube 2053 with the largest inner diameter, the inner diameters of the remaining adjusting tubes 2053 decrease counterclockwise. Starting with the circular piece 208 with the largest diameter, the diameters of the remaining circular pieces 208 decrease clockwise. This allows the circular pieces 208 to indicate the aperture of the adjusting tube 2053 being used and to make a selection. When the threaded bolt 206 is aligned with the circular piece 208 with the largest diameter, the adjusting tube 2053 with the largest aperture is connected to the conical cover 201 and the conical tube 203. When the threaded bolt 206 is aligned with the circular piece 208 with the smallest diameter, the adjusting tube 2053 with the smallest aperture is connected to the conical cover 201 and the conical tube 203.

[0040] Furthermore, the side wall of the oil drum 101 is inlaid with a transparent window 107, and one side of the transparent window 107 is provided with vertically distributed scale lines. The inner cavity of the oil drum 101 is slidably provided with a float 108, and a circular opening is provided at the center of the top of the float 108.

[0041] The remaining oil level in the oil drum 101 can be observed through the transparent window 107. The amount of oil used each time can be recorded through the scale lines. The float 108 can float on the oil surface by buoyancy. When refueling, the oil can pass through the circular opening. The diameter of the float 108 is the same as the inner diameter of the oil drum 101. When air enters the oil drum 101 through the air inlet pipe 104, the float 108 can reduce the fluctuation of the oil surface caused by pressure, so that the oil suction pipe 103 can stably suck up oil.

[0042] During use, the throttle 2051 is rotated according to the required oil mist particles. The disc 208 allows the user to select the corresponding regulating pipe 2053. After the corresponding regulating pipe 2053 is connected to the conical cover 201 and the conical pipe 203, the threaded bolt 206 is rotated to make it threaded into the corresponding internal threaded sleeve 207 to fix the position of the regulating pipe 2053. When it is necessary to change the regulating pipe 2053, the threaded bolt 206 is rotated to prevent it from contacting the internal threaded sleeve 207. Then, the corresponding inner diameter regulating pipe 2053 can be selected again. Then, the air intake of the air intake pipe 104 is adjusted through the valve of the air intake pipe 104, and the oil supply of the oil supply pipe 106 is adjusted through the valve of the oil suction pipe 103.

[0043] Then, an air pump is connected to the air supply pipe 105 to allow high-speed gas to circulate within the air supply pipe 105. Part of the gas in the air supply pipe 105 enters the oil tank 101 through the air inlet pipe 104, and the liquid in the oil suction pipe 103 is transported to the air supply pipe 105 through the oil supply pipe 106. Subsequently, the air will drive the oil through the conical shroud 201, the regulating pipe 2053, and the conical pipe 203 to form an oil mist. The formed oil mist is discharged through the atomizing pipe 204. The remaining amount of oil in the oil tank 101 can be observed through the transparent window 107 and the scale lines. The float 108 can reduce the fluctuation of the oil surface caused by pressure, so that the oil suction pipe 103 can stably suck up oil.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
