[0020] However, the existing drilling machine coolant is disposable and inconvenient to recycle. The coolant is directly scrapped after cooling and cannot be reused, resulting in a waste of resources.

The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

[0023] Embodiment 1: By Figure 1 , 2 As can be seen from Figure 3, a cooling device for a drilling machine for door and window processing includes a body 1, an electric push rod 2 is fixedly connected to the top of the inner wall of the body 1, the electric push rod 2 drives the drill bit 3 to adjust the vertical position, the bottom of the electric push rod 2 is fixedly connected to the drill bit 3, both sides of the drill bit 3 are provided with nozzles 12, the bottom of the nozzle 12 is provided with a workbench 4, both sides of the top of the workbench 4 are provided with clamping plates 17, and the bottom of the clamping plate 17 is provided with a circulation device, the circulation device includes a water inlet pipe 5, a water pump 6, a hose 8, a filter screen 20, a water storage chamber 32 and a water pumping pipe 33, the water storage chamber 32 The outer wall of the water storage chamber 32 is fixedly connected to a water pump 6 arranged at the bottom of the inner wall of the machine body 1, and one end of the water pump 6 is connected to a water pumping pipe 33, and the water pumping pipe 33 extends to the inside of the water storage chamber 32. The other end of the water pump 6 is connected to a water inlet pipe 5, and the other end of the water inlet pipe 5 is connected to a hose 8. The material of the hose 8 is a material that meets the technical solution and is not easily broken during movement. The end of the hose 8 is connected to the nozzle 12. A filter screen 20 is arranged on one side of the water pump 6. The model of the water pump 6 is not limited. The model of the electric push rod 2 is DHLA6000, and the filter screen 20 is plugged into the inner wall of the machine body 1;

[0024] In the specific implementation process, it is worth pointing out that when processing the workpiece, the workpiece is clamped by the clamping plate 17, and the vertical position of the drill bit 3 is adjusted by the electric push rod 2 to make it more accurate in the position of the workpiece. The impurities in the liquid during processing are filtered by the filter 20 through the cooperation of the filter 20, the water pump 6, the nozzle 12 and the water suction pipe 33. The filtered liquid is driven by the water pump 6 to transport the water to the water inlet pipe 5 through the water suction pipe 33, so that the liquid is transported to the nozzle 12. Therefore, the liquid used for processing is filtered by the filter 20 and flows back to the water storage chamber 32, thereby solving the problem that the existing drilling machine coolant is used once and is not convenient for recycling, and the cooled coolant is directly scrapped and cannot be reused, resulting in a waste of resources.

[0025] Further, a connection block 11 is fixedly connected to one side of the nozzle 12 close to the inner wall of the body 1, a first fan 13 is arranged at the bottom of the nozzle 12, the model of the first fan 13 is not limited, the first fan 13 is fixedly connected to the outer wall of the connection block 11, the outer wall of the body 1 is fixedly connected to a first drive motor 14, the model of the first drive motor 14 is JSMA-PUC02D, the output end of the first drive motor 14 extends to the inner wall of the body 1 through a sealed bearing, the output end of the first drive motor 14 is fixedly connected to a driving gear 15, both sides of the inner wall of the body 1 are fixedly connected to slide rails 7, the outer wall of the slide rails 7 is slidably connected to a slider 9, the slider 9 is fixedly connected to the connection block 11, the inner wall of the slider 9 is threadedly connected to a screw rod 10, the bottom of the screw rod 10 is fixedly connected to a driven gear 16, the driving gear 15 is meshed with the driven gear 16, and the screw rod 10 is fixedly connected to the inner wall of the body 1 through a sealed bearing;

[0026] In the specific implementation process, it is worth pointing out that, through the cooperation of the first driving motor 14, the driving gear 15, the driven gear 16 and the screw rod 10, the first driving motor 14 is started to drive the driving gear 15 to rotate. Since the driving gear 15 and the driven gear 16 are meshed with each other, the driven gear 16 drives the screw rod 10 to rotate. The slider 9 is moved in the slide rail 7 through the rotation of the screw rod 10. The slider 9 drives the nozzle 12 and the first fan 13 on the connecting block 11 to move. When the workpiece is processed, the position of the slider 9 is adjusted to make the nozzle 12 on the surface of the workpiece cool more completely. The first fan 13 can quickly cool the liquid sprayed from the nozzle 12, so that it falls on the workpiece to better achieve the cooling effect.

[0027] Specifically, when the cooling device for the drilling machine for door and window processing is used, when the workpiece is being processed, the workpiece is clamped by the clamping plate 17, the vertical position of the drill bit 3 is adjusted by the electric push rod 2, and the impurities in the liquid during processing are filtered through the filter 20 through the cooperation of the filter 20, the water pump 6, the nozzle 12 and the water suction pipe 33. The filtered liquid is driven by the water pump 6 to transport water to the water inlet pipe 5 through the water suction pipe 33, so that the liquid is transported to the nozzle 12. Therefore, the processing liquid is filtered by the filter 20 and flows back to the water storage chamber 32, thereby solving the problem that the existing drilling machine coolant is used once and is not convenient for recycling. The cooled coolant is directly scrapped and cannot be reused, resulting in a waste of resources. The problem of cost is solved. Then, through the cooperation of the first driving motor 14, the driving gear 15, the driven gear 16 and the screw rod 10, the first driving motor 14 is started to drive the driving gear 15 to rotate. Since the driving gear 15 and the driven gear 16 are meshed with each other, the driven gear 16 drives the screw rod 10 to rotate. The slider 9 is moved in the slide rail 7 through the rotation of the screw rod 10. The slider 9 drives the nozzle 12 and the first fan 13 on the connecting block 11 to move. When the workpiece is processed, the position of the slider 9 is adjusted to make the nozzle 12 on the surface of the workpiece cool the workpiece more completely. The first fan 13 can quickly cool the liquid sprayed from the nozzle 12, so that it falls on the workpiece to better achieve the cooling effect.

[0028] Embodiment 2: By Figure 1 , 3 As can be seen from Figure 4, the inner wall of the workbench 4 is rotatably connected with a stud bolt 18 through a bearing, and the outer walls of the stud bolt 18 are respectively threadedly connected to two clamping plates 17 on both sides, and the stud bolt 18 extends to one end of the outside of the workbench 4 and is fixedly connected with a handle 19, and the handle 19 adjusts the position of the stud bolt 18. An elastic member 21 is provided at one end of the filter screen 20 close to the workbench 4, and the elastic member 21 plays a limiting role on the filter screen 20. The elastic member 21 is fixedly connected to the side cavity of the workbench 4, and the end of the elastic member 21 close to the filter screen 20 is fixedly connected with a fixing pin 34, and the fixing pin 34 is movably connected to the side cavity of the workbench 4. The end of the fixing pin 34 is inserted into the side of the filter screen 20, and the front of the fixing pin 34 is fixedly connected with a handle 22. The outer wall of the handle 22 passes through the front of the workbench 4 and the machine body 1 in sequence, and is movably connected to the workbench 4 and the machine body 1. The filter screen 20 is replaced by pulling the handle 22;

[0029] In the specific implementation process, it is worth pointing out that the position of the clamping plate 17 is controlled by adjusting the stud bolt 18 through the handle 19, so that the workpiece is clamped more stably. The filter screen 20 on the workbench 4 is disassembled by pulling the handle 22. When disassembling the filter screen 20, the handle 22 is pulled to deform the elastic member 21, thereby facilitating the replacement of the filter screen 20.

[0030] Furthermore, a liquid inlet pipe 23 is installed on one side of the water storage chamber 32, and the liquid inlet pipe 23 supplies liquid to the inside of the water storage chamber 32. The liquid inlet pipe 23 extends into the inside of the water storage chamber 32, and a piston 25 is inserted at the end of the liquid inlet pipe 23. A sealing gasket is installed inside the piston 25 to ensure a good sealing effect. A connecting rod 26 is fixedly connected to the bottom of the piston 25, and a floating ball 24 is fixedly connected to the bottom of the connecting rod 26. The floating ball 24 serves to detect the position of the liquid. A fixed block 27 is fixedly connected to one side of the water storage chamber 32 close to the connecting rod 26, and the inner wall of the fixed block 27 is inserted with the connecting rod 26. A heat sink 28 is fixedly connected to the bottom of the inner wall of the water storage chamber 32, and a heat sink 29 is fixedly connected to the bottom of the heat sink 28 at an equidistant distance. The heat sink 29 transfers heat to the outside of the water storage chamber 32 through the heat sink 28, and the bottom of the heat sink 29 extends to the outer wall of the water storage chamber 32.

[0031] In the specific implementation process, it is worth pointing out that the liquid inside the water storage chamber 32 is added through the liquid inlet pipe 23, and the piston 25 at the bottom of the liquid inlet pipe 23 is blocked under the action of the float 24. When the liquid inside the water storage chamber 32 is sufficient, the float 24 floats on the top of the liquid. When there is a lack of liquid inside, the float 24 drops. When it drops to a certain height, the float 24 drives the piston 25 to fall, so that the liquid inlet pipe 23 adds liquid to the water storage chamber 32. When the liquid is full, the float 24 drives the piston 25 to continue to block the liquid inlet pipe 23 through the buoyancy force, thereby achieving automatic liquid replenishment when there is a lack of liquid in the water storage chamber 32, thereby reducing labor costs. The liquid inside the water storage chamber 32 transfers heat to the top of the heat sink 29 through the heat sink 28 at the bottom, thereby playing a role in cooling the circulating liquid;

[0032] Furthermore, a second fan 30 fixed to the body 1 is provided below the water storage chamber 32, and the second fan 30 blows air to the heat sink 29 to quickly cool it down. A cooling fin 31 is embedded in the side of the body 1 close to the water pump 6;

[0033] In the specific implementation process, it is worth pointing out that the second fan 30 cools the heat sink 29, which can better cool it down quickly, and transmits the heat source inside the water storage chamber 32 through the cooling plate 31, which plays a better role in cooling the liquid inside the water storage chamber 32;

[0034] Specifically, on the basis of the above-mentioned embodiment 1, when processing the workpiece, the handle 19 is used to adjust the stud bolt 18 to control the position of the clamping plate 17, so that it can clamp the workpiece more stably. When the filter screen 20 is blocked, the filter screen 20 is disassembled by pulling the handle 22. When disassembling the filter screen 20, the handle 22 is pulled to deform the elastic member 21, thereby facilitating the replacement of the filter screen 20. The liquid inside the water storage chamber 32 is added through the liquid inlet pipe 23, and the piston 25 at the bottom of the liquid inlet pipe 23 is blocked under the action of the float 24. When the liquid inside the water storage chamber 32 is sufficient, the float 24 floats on the top of the liquid. When there is a lack of liquid inside, the float 24 descends. When it descends to a When the height is fixed, the float 24 drives the piston 25 to fall, so that the liquid inlet pipe 23 adds liquid to the water storage chamber 32. When the liquid is full, the float 24 drives the piston 25 to continue to block the liquid inlet pipe 23 through the buoyancy force, thereby achieving automatic liquid replenishment when there is a lack of liquid in the water storage chamber 32, thereby reducing labor costs. The liquid in the water storage chamber 32 transfers heat to the top of the heat sink 29 through the heat sink 28 at the bottom, thereby playing a role in cooling the circulating liquid. The heat sink 29 is then cooled by the second fan 30, which can better and quickly cool it down. The heat source in the water storage chamber 32 is transmitted through the refrigeration plate 31, which has a better cooling effect on the liquid in the water storage chamber 32.
