Description

[0001] This invention relates to the field of graphite product drilling technology, specifically to a self-positioning drilling device for graphite products. Background Technology

[0002] Graphite products are widely used in many fields such as metallurgy, photovoltaics, semiconductors, and machinery manufacturing due to their excellent properties such as high temperature resistance, electrical and thermal conductivity, and good chemical stability. Drilling is a crucial process in the forming of graphite products. During use, traditional equipment cannot form a uniform turbulent flow of water mist inside the protective cover, making it difficult to cover the drilling dead corners. This causes dust to easily drift out from the gaps in the protective cover, polluting the working environment and endangering the health of the operators. Furthermore, the residual dust can easily adhere to the hole wall and drill bit, further affecting the drilling accuracy. Summary of the Invention

[0003] This invention uses airflow to create internal turbulence by driving water mist, which precisely covers the gaps and blind spots of drilling. This allows the water mist to fully absorb and combine with the dust, effectively suppressing the overflow and dispersion of graphite drilling dust, improving the working environment. At the same time, the airflow inside the protective cover can quickly remove the frictional heat from the drilling location, continuously cooling the drill bit, preventing high-temperature wear or burning, extending the life of the drill bit, and ensuring drilling accuracy.

[0008] Preferably, the two sets of guide tubes are fixed to both sides of the drill bit by clips, and the output ends of the two sets of guide tubes face the drilling end of the drill bit.

[0009] Preferably, multiple sets of blades are fixedly connected to the outer side of the two sets of rotating shafts, and both sets of rotating shafts are rotatably connected to the inner wall of the protective cover, and the two sets of rotating shafts are respectively located on one side of the two sets of jet slots.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] Reference Figures 1 to 7 This invention provides a self-positioning drilling device for graphite products, including a worktable 1, a drainage groove 2 at the upper end of the worktable 1, two sets of limit buckles 25 sliding on the upper surface of the worktable 1, a bracket 3 installed at the upper end of the worktable 1, an electric push rod 4 installed at the upper end of the bracket 3, a drill bit 6 fixedly connected to one end of the electric push rod 4, a protective cover 5 provided on the outside of the drill bit 6, two sets of spray pipes 7 installed inside the protective cover 5, multiple sets of nozzles installed on the outside of each of the two sets of spray pipes 7, a connecting pipe A8 for conveying water source connected to one side of each of the two sets of spray pipes 7, and a valve A provided inside each of the connecting pipes A8, the valve A being opened and closed by the sliding of the drill bit 6; Two sets of air jets 10 are installed on both sides of the inner wall of the protective cover 5. One side of each set of air jets 10 is connected to a connecting pipe B11 for conveying airflow. Each set of connecting pipes B11 is equipped with a valve B. The valve B is opened and closed by sliding the drill bit 6. Both sides of the drill bit 6 are equipped with air collection grooves 14. The other end of each set of air collection grooves 14 is connected to a guide pipe 15. Inside the protective cover 5, there are two sets of rotating shafts 16 driven by the jet grooves 10. Two sets of guide tubes 18 are installed on one side of the protective cover 5. Inside each set of guide tubes 18, there are pistons 20 driven by the two sets of rotating shafts 16. One end of each set of guide tubes 18 is connected to a storage tank 22. One side of each set of storage tanks 22 is connected to two sets of nozzles 7.

[0020] In an optional embodiment, two sets of cylinders 24 are installed on the upper surface of the workbench 1. The output ends of the two sets of cylinders 24 are respectively connected to two sets of limit buckles 25. The drainage groove 2 is opened at the center of the upper end of the workbench 1, and the drainage groove 2 and the protective cover 5 are located on the same vertical plane. When using the device, the operator places the graphite plate to be drilled at the center of the upper end of the workbench 1. After the graphite plate is placed, the two sets of cylinders 24 will push the two sets of limit buckles 25 to clamp and fix the graphite plate. During the drilling process, the two sets of cylinders 24 can push the two sets of limit buckles 25 to slide, thereby moving the graphite plate as a whole, and thus changing the drilling position of the graphite plate during the drilling process.

[0021] In an optional embodiment, the protective cover 5 is magnetically connected to the electric actuator 4, and racks 13 are fixedly connected to both sides of the bracket 3. The other end of the connecting pipe A8 is connected to the water supply equipment. One end of the valve A is fixedly connected to the valve stem A, and the other end of the valve stem A passes through the connecting pipe A8 and extends to the outside of the connecting pipe A8. The other end of the valve stem A is fixedly connected to the gear A9. The gear A9 and the rack 13 are located on the same vertical plane, and the rack 13 and the gear A9 mesh. After the graphite plate is fixed by the two sets of cylinders 24, the electric actuator 4 drives the drill bit 6 to descend and drill a hole in the graphite plate. As the electric actuator 4 pushes the drill bit 6 down, it simultaneously drives the protective cover 5 down. When the protective cover 5 descends to contact the upper surface of the worktable 1, it slides along the outer wall of the electric actuator 4 as the actuator 4 continues to descend. Once in contact with the upper surface of the worktable 1, the protective cover 5 shields the outside of the graphite plate, preventing dust from splashing around during drilling. Furthermore, as the protective cover 5 descends, it... The connecting pipe A8 descends synchronously, and as it descends, it drives the gear A9 to descend as well. When the gear A9 descends and contacts the rack 13, the gear A9 rotates through the rack 13 as the connecting pipe A8 continues to move. After the rack 13 rotates, it opens the valve A inside the connecting pipe A8 through the valve stem A. Once the valve A is open, water enters the nozzle 7 through the connecting pipe A8. After the water enters the nozzle 7, it is sprayed into the protective cover 5 in an atomized state through multiple nozzles.

[0022] In an optional embodiment, the other end of the connecting pipe B11 is connected to the fan, one end of the valve B is fixedly connected to the valve stem B, the other end of the valve stem B passes through the connecting pipe B11 and extends to the outside of the connecting pipe B11, and the other end of the valve stem B is connected to the gear B12, the gear B12 meshes with the rack 13, and the gear B12 and the rack 13 are located in the same vertical plane. As described above, when the protective cover 5 descends, it simultaneously drives the connecting pipe B11 to descend as well. When the connecting pipe B11 descends, it simultaneously drives the gear B12 to descend as well. When the gear B12 descends and contacts the rack 13, the gear B12 rotates through the rack 13. As the gear B12 rotates, it opens the valve B inside the connecting pipe B11 via the valve stem B. Once the valve B is open, airflow is ejected into the protective cover 5 through the jet vent 10. Therefore, during drilling, as the protective cover 5 descends, the water source and airflow are automatically released. Furthermore, when the airflow acts on the inside of the protective cover 5, it pushes the atomized water source to form inside the protective cover 5. The turbulent flow, through which the airflow carries the water mist inside the protective cover 5, allows it to better contact the drilling dead corners, reducing dust generation. At the same time, when the airflow acts inside the protective cover 5, the flow of the airflow can quickly remove the heat from the water source at the drilling location, thus keeping the drill bit 6 in a suitable temperature environment. The water mist, driven by the airflow, forms internal turbulence, accurately covering the gaps in the drilling dead corners, allowing the water mist and dust to be fully adsorbed and combined, effectively inhibiting the overflow and dispersion of graphite drilling dust, improving the working environment. Meanwhile, the airflow inside the protective cover 5 can quickly remove the frictional heat at the drilling location, continuously cooling the drill bit, preventing high-temperature wear or burning of the drill bit, extending the service life of the drill bit, and ensuring drilling accuracy. After drilling is completed, as the electric actuator 4 drives the drill bit 6 to rise, the electric actuator 4 will simultaneously drive the protective cover 5 to rise. When the protective cover 5 rises, it will slide downwards on the outside of the electric actuator 4 due to its own weight. When the protective cover 5 returns to its original position, gears A9 and B12 will contact the rack 13 again, and then gears A9 and B12 will rotate again to close valves A and B inside the connecting pipes A8 and B11.

[0023] In an optional embodiment, the two sets of guide tubes 15 are fixed to both sides of the drill bit 6 by snap-fit, and the output ends of the two sets of guide tubes 15 are facing the drilling end of the drill bit 6. As described above, when the two sets of jet channels 10 deliver airflow into the protective cover 5, some of the airflow will enter the air collection channel 14. After entering the air collection channel 14, the airflow will be ejected outward through the other end of the guide pipe 15. Since one end of each of the two guide pipes 15 faces the drilling end of the drill bit 6, the two guide pipes 15 will continuously apply airflow to the drilling point when the drill bit 6 is drilling. Furthermore, because the diameter of the guide pipe 15 is small, the airflow velocity increases when it flows through the guide pipe 15. Consequently, when the airflow acts on the drilling point, it is accelerated. The airflow will blow the residue remaining in the hole outward, thereby reducing the residue inside the hole when the drill bit 6 is drilling. This is achieved by reducing the diameter of the guide tube 15 to create an airflow acceleration effect, increasing the airflow impact force. The high-speed airflow is precisely blown directly to the drilling end of the drill bit, which can promptly blow the graphite residue inside the hole outward, reducing the accumulation of residue inside the hole and preventing residue residue from causing scratches on the hole wall or hole diameter deviation. This ensures the smoothness and processing accuracy of the hole inner wall. At the same time, timely slag removal can reduce the probability of the drill bit getting stuck due to friction with the residue, reduce drill bit wear, and improve the stability of continuous drilling operations.

[0024] In an optional embodiment, multiple sets of blades 17 are fixedly connected to the outer sides of the two sets of rotating shafts 16, and both sets of rotating shafts 16 are rotatably connected to the inner wall of the protective cover 5, and the two sets of rotating shafts 16 are respectively located on one side of the two sets of jet slots 10. When the airflow is blown out through the jet duct 10, the airflow will cause multiple sets of blades 17 to rotate. When the multiple sets of blades 17 rotate, the multiple sets of blades 17 will synchronously drive the rotating shaft 16 to rotate.

[0025] In an optional embodiment, the other ends of both sets of rotating shafts 16 penetrate through the protective cover 5 and extend to the outside of the protective cover 5. One end of each set of rotating shafts 16 is fixedly connected to a reciprocating screw 19, and the two sets of reciprocating screws 19 extend into the interior of the two sets of guide tubes 18 respectively. As described above, when the rotating shaft 16 rotates, the rotating shaft 16 will synchronously drive the reciprocating screw 19 to rotate inside the guide tube 18.

[0026] In an optional embodiment, the reciprocating lead screw 19 is connected to the piston 20 ball nut pair, and both sets of guide tubes 18 are provided with guide grooves, and the piston 20 is slidably connected to the guide grooves. When the reciprocating screw 19 rotates, it drives the piston 20 to reciprocate along the guide groove inside the guide tube 18.

[0027] In an optional embodiment, one end of the guide tube 18 is connected to a hose A21, the other end of the hose A21 is connected to the storage tank 22, one side of the storage tank 22 is connected to a hose B23, the other end of the hose B23 passes through the protective cover 5 and extends into the interior of the protective cover 5 to connect with the nozzle 7, and a one-way valve is provided at the connection between the hose B23 and the nozzle 7. The storage tank 22 contains water-based lubricating mist. When the piston 20 moves back and forth, the piston 20 continuously supplies gas to the storage tank 22 through the hose A21. When the gas enters the storage tank 22, it compresses a small amount of water-based lubricating mist inside the storage tank 22 and sends it through the hose B23 into the nozzle 7. After the water-based lubricating mist enters the nozzle 7, it is diluted by the water source and sprayed out through the nozzle, thereby reducing the friction coefficient between the drill bit and the graphite hole wall, reducing tool wear, and making drilling smoother. The lubricating mist, after being diluted by the water source, is sprayed out from the nozzle and can act evenly on the contact position between the drill bit and the graphite hole wall, continuously forming a lubricating protective film, reducing dry grinding and high-temperature wear of the drill bit, extending the service life of the drill bit, reducing replacement costs, and at the same time, the lubrication effect makes the drilling feed smoother, prevents edge chipping or hole wall scratches, and improves the smoothness and processing accuracy of the inner wall of the graphite product hole.

[0028] Working principle: When using the device, the operator places the graphite plate to be drilled at the center of the upper end of the workbench 1. After the graphite plate is placed, the two sets of cylinders 24 will push the two sets of limit buckles 25 to clamp and fix the graphite plate. During the drilling process, the two sets of cylinders 24 can push the two sets of limit buckles 25 to slide, thereby moving the graphite plate as a whole, and thus changing the drilling position of the graphite plate during the drilling process. After the graphite plate is fixed by the two sets of cylinders 24, the electric actuator 4 drives the drill bit 6 to descend and drill a hole in the graphite plate. When the electric actuator 4 pushes the drill bit 6 down, it will simultaneously drive the protective cover 5 down. When the protective cover 5 descends to contact the upper surface of the worktable 1, it will slide on the outer wall of the electric actuator 4 as the electric actuator 4 continues to descend. When the protective cover 5 contacts the upper surface of the worktable 1, it will shield the outside of the graphite plate, thus preventing dust from splashing around during drilling. When the protective cover 5 descends, it will simultaneously drive the connecting pipe A8 down. When the connecting pipe A8 descends, it will simultaneously drive the gear A9 down. When the gear A9 descends and contacts the rack 13, it will rotate through the rack 13 as the connecting pipe A8 continues to move. After the rack 13 rotates, it will open the connecting pipe A through the valve rod A. When valve A inside pipe 8 is opened, water will enter the nozzle 7 through connecting pipe A8. After entering the nozzle 7, the water will be sprayed into the protective cover 5 in an atomized state through multiple nozzles. When the protective cover 5 descends, the protective cover 5 will simultaneously drive the connecting pipe B11 to descend. When the connecting pipe B11 descends, the connecting pipe B11 will simultaneously drive the gear B12 to descend. When the gear B12 descends and contacts the rack 13, the gear B12 will rotate through the rack 13. When the gear B12 rotates, the gear B12 will open the valve B inside the connecting pipe B11 through the valve stem B. When the valve B is opened, the airflow will be sprayed into the protective cover 5 through the jet vent 10. Thus, when drilling, as the protective cover 5 descends, the water and airflow will automatically be sprayed out. When the airflow acts on the inside of the protective cover 5, the airflow will push the atomized water to form turbulence inside the protective cover 5. When the two sets of jet channels 10 deliver airflow to the inside of the protective cover 5, some of the airflow will enter the inside of the air collection channel 14. After the airflow enters the inside of the air collection channel 14, the airflow will be ejected outward through the other end of the guide pipe 15. Since one end of each of the two sets of guide pipes 15 is facing the drilling end of the drill bit 6, when the drill bit 6 is drilling, the two sets of guide pipes 15 will continuously act the airflow on the drilling point. And because the diameter of the guide pipe 15 is small, the airflow speed will increase when the airflow flows through the guide pipe 15. When the airflow acts on the drilling point, the accelerated airflow will blow the residue remaining in the hole outward, thereby reducing the residue inside the hole when the drill bit 6 is drilling. When the airflow is blown out through the jet duct 10, the airflow will cause multiple sets of blades 17 to rotate. When the multiple sets of blades 17 rotate, they will synchronously drive the rotating shaft 16 to rotate. When the rotating shaft 16 rotates, it will synchronously drive the reciprocating screw 19 to rotate inside the guide tube 18. When the reciprocating screw 19 rotates, it will drive the piston 20 to reciprocate along the guide groove inside the guide tube 18. When the piston 20 reciprocates, it will continuously deliver gas to the storage tank 22 through the hose A21. When the gas enters the storage tank 22, it will squeeze a small amount of water-based lubricating mist inside the storage tank 22 and enter the nozzle 7 through the hose B23. When the water-based lubricating mist enters the nozzle 7, it will be diluted by the water source and sprayed out through the nozzle.
