[0002] Granite drilling technology is a commonly used technology in stone processing. It involves many fields, including architecture, decoration, sculpture, etc. Through a high-speed rotating drill bit, the granite is drilled under the action of pressure. When processing granite into decorations, it is often necessary to drill holes on the corners of the stone for the sake of beauty, so as to facilitate the installation of screws and other connecting structures.

[0003] However, when drilling granite, in order to ensure that the twist drill can accurately guide the cooling into the drill hole during drilling, so that the rotating head of the twist drill can repeatedly dissipate heat, holes for guiding the coolant are often opened on the drill bit to improve the cooling effect. However, these holes are often blocked by stone particles, resulting in uneven discharge of the coolant. At the same time, if the hole is too smooth during the drilling process, it is easy to reduce the drilling efficiency of the twist drill. Summary of the invention

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. The conical grinding disc rotates to grind the gravel in the conical grinding bin into fine gravel, and then transmits it to the inside of the water storage bin through the spiral shaft. The gravel fine gravel and the coolant are evenly mixed by the stirring wheel, and then the stirred coolant is guided to the inside of the guide tube by the water pump. Then, when the coolant mixed with the gravel fine gravel flows out from the third flow channel, the gravel fine gravel with larger particles will be ground twice on the inner wall of the grinding groove through the rotation of the twist drill, and finally flow out through the water outlet, so that the coolant can be better added to the hole during the drilling process of the twist drill, thereby improving the heat dissipation effect.

The water pump continuously drains water from the guide tube, so that the water pressure inside the guide tube increases and the coolant flows into the negative pressure bag, so that the negative pressure bag is continuously expanded. When the storage value of the negative pressure bag exceeds half of its capacity, the cylinder drives the twist drill to rise through the wire connection. During the lifting of the twist drill, the guide tube is pushed to slide upward. During the sliding of the guide tube, the flow slot 1 is blocked. After that, the pressure increased by the water pump drainage will be concentrated inside the negative pressure bag. Then, as the guide tube continues to rise, the baffle 2 will also be lifted. Through the elastic restoring force of the negative pressure bag, the cooling water inside the negative pressure bag will form a strong water flow and be discharged from the output end of the cleaning pipe, impacting the twist drill on the vehicle surface, thereby flushing out the stone particles stuck on the inner wall of the water outlet from the outside. When the water pressure inside the guide tube cannot push the stone particles out from the inside out, a stronger water flow is formed through the negative pressure bag to flush and remove the stone particles from the outside.

[0017] See also Figure 1-Figure 8The present invention provides a technical solution: a drilling device for natural granite, comprising an operating table 1, a clamping structure is installed on the upper end of the operating table 1, a granite plate 5 is arranged on the upper end of the clamping structure, a collecting and grinding structure is installed on the upper end of the granite plate 5, a material guide cylinder 32 is fixedly installed on the side of the collecting and grinding structure away from the collecting shell 4, a spiral shaft 33 is rotatably connected in the cavity of the material guide cylinder 32, a sliding rod 2 is slidably connected to one side of the operating table 1, a mounting shell 3 is welded on the upper end of the sliding rod 2 close to the operating table 1, and a mounting shell 3 is installed. A water storage bin 9 is fixedly installed on the inner wall of the housing 3, and the water storage bin 9 is connected to the guide cylinder 32. A water pump 10 is fixedly installed on the upper end of the water storage bin 9. A connecting pipe is connected to the side of the water pump 10 away from the water storage bin 9. The end of the connecting pipe away from the water pump 10 is connected to a guide block 11. The lower end of the guide block 11 is connected to a sliding pipe 14. The outer wall of the sliding pipe 14 is sleeved with a spring 13. The lower end of the sliding pipe 14 is slidably connected to the guide cylinder 12. The lower end of the guide cylinder 12 is slidably connected to the guide pipe 15. The upper end of the guide pipe 15 A baffle 16 is fixedly installed, and a plurality of flow grooves 17 are opened on the outer wall of the upper end of the guide tube 15, and the flow groove 17 can be connected with the guide tube 12. The lower end of the mounting shell 3 is movably connected with a twist drill 8, and a grinding groove 47 is opened on the upper end of the twist drill 8, and the grinding groove 47 is sleeved on the outer wall of the guide tube 15, and the grinding groove 47 is connected with the guide tube 15. A guide hole 51 connected with the grinding groove 47 is opened inside the twist drill 8, and a water outlet hole connected with the guide hole 51 is opened on the outer wall of the lower end of the twist drill 8 52, a positioning shaft 50 is rotatably connected to the outer wall of the twist drill 8, and a cylinder 39 is fixedly installed on the upper end of the positioning shaft 50. The cylinder 39 is fixedly installed on the outer wall of the mounting shell 3, and the cylinder 39 is connected to the alarm 53 by wire. The positioning shaft 50 limits the rotation of the twist drill 8, and the positioning shaft 50 can be pushed by the cylinder 39 to make the twist drill 8 move up and down, wherein the inner diameter of the grinding groove 47 is larger than the outer diameter of the guide tube 15, and the connection between the guide tube 15 and the upper end of the twist drill 8 is a sealed connection; The outer wall of the guide tube 12 is connected to two symmetrically distributed bent tubes 18, and a sleeve 19 is fixedly installed at the lower end of each bent tube 18. A positioning tube 21 is slidably connected to the inner wall of the sleeve 19, and a spring 20 is fixedly connected between the positioning tube 21 and the sleeve 19. A negative pressure bag 22 is slidably connected to the outer wall of the lower end of the positioning tube 21, and the negative pressure bag 22 is fixedly installed on the inner wall of the mounting shell 3. An alarm 53 is fixedly installed on the upper end of the negative pressure bag 22, and the lower end of the negative pressure bag 22 is connected to a cleaning tube 25. A baffle 23 is fixedly installed at the lower end of the positioning tube 21, and the lower end of the baffle 23 can conflict with the upper notch of the cleaning tube 25. A plurality of flow grooves 24 are opened on the outer wall of the positioning tube 21, among which, Figure 3 As shown, the lower end of the cleaning tube 25 is bent, so that when the twist drill 8 is lifted to the highest height, the output end of the cleaning tube 25 can directly spray cooling water toward the drill bit of the twist drill 8.

[0018] Specifically, the coolant in the water storage tank 9 can be pumped out by the water pump 10, and then introduced into the interior of the guide block 11 through the connecting pipe, and the guide block 11 is then introduced into the interior of the guide tube 12 through the sliding tube 14. At this time, if the twist drill 8 does not apply an upward thrust to the guide tube 12, the sliding rod 2 is pushed by the spring 13, so that the baffle 16 does not conflict with the bottom of the inner cavity of the guide tube 12, and the flow groove 17 will be connected with the guide tube 12. At this time, as the water pump 10 introduces coolant water into the guide tube 12, the coolant in the guide tube 12 will flow through the flow groove 17 into the interior of the guide tube 15, and then flow through the guide tube 15 into the interior of the grinding groove 47, and then conduct through the guide hole 51. The coolant will eventually flow out from the notch of the water outlet hole 52, so that when the twist drill 8 drills the granite slab 5, the coolant can flow into the inside of the drilled hole more accurately, thereby promoting the heat dissipation effect of the twist drill 8; Next, when the twist drill 8 drills a hole in the granite slab 5, if there are stones embedded in the inner wall of the water outlet hole 52, if the water flow pressure generated by the cooling water delivered by the water pump 10 cannot flush out the stones, then the normal drainage volume of the water outlet hole 52 will be less than the delivery volume of the water pump 10, which will cause the water pressure inside the guide tube 12 to increase, and at the same time, the drainage volume of the water outlet hole 52 that is not blocked by stones will increase, thus becoming turbulent. If the stones inside the water outlet hole 52 cannot be pushed out from the inside to the outside by the water pressure, then the water flow inside the guide tube 12 will flow into the inside of the negative pressure bag 22 through the bent tube 18. The negative pressure bag 22 is made of a tough material, and the water pressure The cooling water inside the negative pressure bag 22 will continue to increase, and the inner cavity of the negative pressure bag 22 will be continuously expanded. If the stone particles cannot be discharged and the pressure is released, when the cooling water accumulated inside the negative pressure bag 22 exceeds half of its storage value, the alarm 53 will sound an alarm, and the cylinder 39 connected to the alarm 53 wire will start, driving the twist drill 8 to rise and lift the knife. Then, during the rising process of the twist drill 8, the twist drill 8 will conflict with the guide tube 12 and push it. As the guide tube 12 moves upward, the flow slot 17 will be gradually blocked. During the rising process of the guide tube 12, the bending tube 18 will also be lifted together. However, the elastic restoring force of the spring 20 The positioning cylinder 21 will still be pushed, causing the upper notch of the cleaning tube 25 to still be blocked by the baffle 23. At this time, as the flow slot 17 is gradually blocked, the discharge of cooling water will be further reduced, and the water pressure inside the guide cylinder 12 will be further increased. At this time, the excess cooling water will be completely injected into the negative pressure bag 22, and the water pressure inside the negative pressure bag 22 will be further increased. When the flow slot 17 is completely blocked, the elastic restoring force of the spring 20 has been released. When the guide cylinder 12 continues to move upward, the baffle 16 is fitted with the bottom of the inner cavity of the guide cylinder 12. At this time, the baffle 23 will be pulled upward by the bending tube 18, and the baffle 22 The lifting will release the cooling water in the negative pressure bag 22, and the strong water flow in the negative pressure bag 22 will be completely discharged through its own elastic restoring force. At this time, the twist drill 8 has been lifted to a certain height. The position of the water outlet 52 at this time allows the cooling water to be directly sprayed to the position of the water outlet 52 through the output end of the cleaning pipe 25, so that the water outlet 52 is flushed with a stronger water flow from the outside, so that the stone particles stuck in the water outlet 52 can be flushed out. At the same time, if the water outlet 52 is not stuck by the stone particles, the cooling liquid can also clean the outer surface of the twist drill 8 through the cleaning pipe 25 by lifting the guide tube 12.

[0019] Among them, the collecting and grinding structure includes a collecting shell 4, and the collecting shell 4 can be movably connected to the twist drill 8, an arc groove 29 is opened on the inner side wall of the upper notch of the collecting shell 4, and the inner wall of the arc groove 29 is slidably connected with a scraping plate 6, and the scraping plate 6 is in contact with the inner cavity bottom of the collecting shell 4, the inner cavity bottom of the collecting shell 4 is rotatably connected with a conveyor belt 7, and the conveyor belt 7 extends to the outside of the cavity of the collecting shell 4, the lower end of the collecting shell 4 is fixedly installed with a conical grinding bin 26, and the conical grinding bin 26 does not contact the granite slab 5, the upper notch of the conical grinding bin 26 is provided with a rotatable conical grinding disc 27, the upper end of the conical grinding disc 27 is fixedly installed with a connecting rod 30, and the connecting rod 30 is rotatably connected to the mounting shell 3, and the water storage bin 9 is internally rotated. A stirring wheel 31 is dynamically connected to the water storage bin 9, and the lower end of the stirring wheel 31 is fixedly connected to the connecting rod 30. A motor 35 is fixedly installed on the upper end of the water storage bin 9. The output end of the motor 35 and the upper end of the spiral shaft 33 and the stirring wheel 31 are jointly sleeved with a transmission belt 36. A bevel block 34 is fixedly installed on the inner wall of the mounting shell 3, and the bevel block 34 is sleeved on the outer wall of the guide cylinder 32. The upper end of the water storage bin 9 is connected to a water inlet 37. A water diversion pipe 38 is fixedly installed at one end of the water pump 10. The water diversion pipe 38 passes through the cavity of the water storage bin 9, and the water diversion pipe 38 does not contact the stirring wheel 31. A scraper rod 28 is fixedly installed on the inner wall of the upper end of the grinding bin 26, and the scraper rod 28 conflicts with the upper end of the conical grinding disc 27.

[0020] Specifically, the lower end of the collecting shell 4 is in contact with the upper surface of the granite slab 5. When the scraping plate 6 slides inside the arc chute 29, the scraping plate 6 will scrape a circle around the twist drill 8, and the scraping plate 6 will not contact the twist drill 8. When the scraping plate 6 rotates one circle, the stone particles and gravel fines produced by the twist drill 8 drilling the granite slab 5 will be scraped onto the upper surface of the conveyor belt 7. At the same time, there are several drainage grooves on the conveyor belt 7, which can separate the stone particles from the coolant during the transmission process. Then, with the transmission of the conveyor belt 7, the stone particles will eventually fall into the interior of the conical grinding bin 26. At the same time, the motor 35 drives the conical grinding disc 27 to rotate. Figure 7As shown in the figure, the gap between the inner wall of the conical grinding chamber 26 and the outer wall of the conical grinding disc 27 will gradually become smaller. As the conical grinding disc 27 rotates, the large stone particles will be continuously ground into fine stone powder. At the same time, as the conical grinding disc 27 rotates, the stone particles falling on the upper surface of the conical grinding disc 27 will be scraped by the scraper rod 28. At the same time, due to the action of centrifugal force, the stone particles will eventually roll down to between the conical grinding chamber 26 and the conical grinding disc 27. Then, the ground fine stone powder will be discharged from the conical grinding chamber 26. The lower end of the grinding bin 26 rolls down to the inside of the guide cylinder 32, and is then transported to the cavity of the water storage bin 9 through the screw shaft 33, and slides down through the bevel of the bevel block 34. At the same time, the motor 35 drives the stirring wheel 31 to rotate so that the coolant and the crushed stone powder inside the water storage bin 9 are evenly mixed, and then the two are pumped out together through the water pump 10 and sprayed out from the water outlet 52. The coolant with crushed stone powder can increase the friction between the two when the hemp drill 8 drills a hole in the granite slab 5, thereby improving the drilling efficiency.

[0021] Among them, the outer wall of the twist drill 8 is sleeved with a long gear sleeve 40, and the long gear sleeve 40 is slidably connected to the mounting shell 3. A motor 2 41 is fixedly installed on the bottom of the inner cavity of the mounting shell 3, and a driving gear 42 is fixedly installed on the output end of the motor 2 41, and the driving gear 42 and the long gear sleeve 40 are meshed with each other. The driving gear 42 is driven to rotate by the rotation of the motor 2 41, and the driving gear 42 drives the long gear sleeve 40 meshed with it to rotate, and the long gear sleeve 40 drives the twist drill 8 to rotate, so that the twist drill 8 can drill holes in the granite slab 5.

[0022] Among them, a plurality of flow grooves 3 48 are opened at equal intervals on the outer wall of the guide pipe 15, and a conical filter plate 49 is fixedly installed on the inner wall of the flow groove 3 48 close to the guide pipe 15, and the lower end of the conical filter plate 49 is flush with the bottom of the inner cavity of the flow groove 3 48. The conical filter plate 49 prevents large particles of crushed stone and fine powder from sinking to the bottom. At the same time, the conical structure of the conical filter plate 49 allows the filtered large particles of crushed stone and fine powder to slide into the inside of the flow groove 3 48. Each flow groove 3 48 is opened at one end away from the conical filter plate 49. A downwardly arranged bevel groove is provided, such as Figure 8 As shown, there is a gap between the outer wall of the guide tube 15 and the inner wall of the grinding groove 47. When the coolant carries the crushed stone particles out of the flow groove three 48, if there are too large crushed stone particles, they will collide with the inner wall of the grinding groove 47 along the beveled edge of the outer side of the flow groove three 48. Therefore, when the twist drill 8 rotates, the crushed stone particles clamped by the beveled groove of the flow groove three 48 and the grinding groove 47 will be ground for the second time.

[0023] Among them, the clamping structure includes a plurality of electric lifting rods 43, the lower end of each electric lifting rod 43 is fixedly connected to the operating table 1, and a support plate 44 is fixedly installed on the output end of the electric lifting rod 43. A plurality of support rods 45 are slidably connected to the upper end of the support plate 44, and the support rods 45 are in conflict with the granite slab 5. Two electric clamping rods 46 are symmetrically distributed on the outer wall of the support plate 44, and the granite slab 5 is clamped between the two electric clamping rods 46. The granite slab 5 of different sizes is supported by sliding a plurality of support rods 45. At the same time, there are gaps between the support rods 45 so that the twist drill 8 will not be interfered by the support rods 45 when drilling through the granite slab 5. Then the granite slab 5 is clamped by the two electric clamping rods 46, and at the same time, the electric lifting rod 43 can drive the granite slab 5 to rise and fall to a suitable height.

[0024] Working principle: The granite slab 5 is clamped by the clamping structure, and then the motor 2 41 drives the twist drill 8 to rotate through the driving gear 42 and the long gear sleeve 40, and at the same time, the cylinder 39 pushes the twist drill 8 to descend through the positioning shaft 50, so that the twist drill 8 drills the granite slab 5. At the same time, during the drilling process, the crushed stones discharged by the twist structure of the twist drill 8 will be scraped to the upper end of the conveyor belt 7 by the scraping plate 6, and then the conveyor belt 7 transmits the crushed stones to the inside of the conical grinding bin 26. Through the rotation of the conical grinding disc 27, the crushed stones inside the conical grinding bin 26 are initially ground into fine crushed stones, and then transmitted through the spiral shaft 33 To the inside of the water storage bin 9, the crushed stone fines are evenly mixed with the coolant through the stirring wheel 31, and then the stirred coolant is guided to the inside of the guide tube 12 through the water pump 10. Then, when the coolant mixed with the crushed stone fines flows out from the flow channel 3 48, the crushed stone fines with larger particles will be secondary ground on the inner wall of the grinding groove 47 through the rotation of the twist drill 8, and finally flow out through the water outlet 52, so that during the drilling process of the twist drill 8, the coolant can be better added to the hole, thereby improving the heat dissipation effect. At the same time, the coolant added with the crushed stone fines can increase the friction between the twist drill 8 and the granite slab 5 when drilling the hole, thereby improving the drilling efficiency. Next, the twist drill 8 is lifted by the cylinder 39, so that the upper end of the twist drill 8 contacts the guide tube 12, thereby pushing the guide tube 12 to slide. During the sliding process of the guide tube 12, the flow groove 17 is blocked, so that the coolant cannot flow into the guide hole 51 through the guide tube 15 and then flow out through the water outlet 52. During the lifting process of the guide tube 12, the bending tube 18 and the second baffle 23 are driven to slide upward. During the sliding process of the baffle 23, the upper notch of the cleaning tube 25 is no longer blocked, so that the coolant can flow out from the guide tube 15 and then sprayed on the outer surface of the twist drill 8, so that the outer wall of the twist drill 8 can be cleaned every time the twist drill 8 is lifted; When the twist drill 8 is rotating, if stones get stuck on the inner wall of the water outlet hole 52, and the stones cannot be flushed out by the water pressure inside the guide tube 12, the water pump 10 will continuously drain the water into the guide tube 12, so that the water pressure inside the guide tube 12 gradually increases. The increase in water pressure will cause the coolant that cannot be quickly discharged to flow into the negative pressure bag 22 through the bent tube 18, so that the negative pressure bag 22 is continuously expanded. When the storage value of the negative pressure bag 22 exceeds half of the capacity, the alarm 53 starts to alarm, and the cylinder 39 drives the hemp pump 53 to rotate. The twist drill 8 is lifted, and during the lifting process, the guide tube 12 is pushed to slide upward. During the sliding process of the guide tube 12, the flow slot 17 is blocked. After that, the increased pressure of the water pump 10 due to drainage will be all concentrated inside the negative pressure bag 22. Then, as the guide tube 12 continues to rise, the baffle 23 will also be lifted. Through the elastic restoring force of the negative pressure bag 22, the cooling water inside the negative pressure bag 22 will form a strong water flow and be discharged from the output end of the cleaning pipe 25, impacting the twist drill 8 on the vehicle surface, thereby flushing out the stones stuck on the inner wall of the water outlet 52 from the outside.
