A drilling device and a drilling method for a porous ceramic adsorption platform

Abstract

This invention discloses a drilling device and a drilling method for a porous ceramic adsorption platform, relating to the technical field of drilling equipment. In this invention, a dust discharge cylinder is movably mounted on the outer ring of the drill bit. During the drilling process, the dust discharge cylinder remains in contact with the surface of the porous ceramic adsorption platform, sealing and isolating the drilling location from the outside environment. This prevents dust generated during drilling from spreading outwards and polluting the air or entering the pores of the porous ceramic adsorption platform, thereby improving the yield rate of the porous ceramic adsorption platform. Furthermore, the dust discharge cylinder is connected to an external negative pressure suction device via a guide section, allowing the external negative pressure suction device to continuously draw negative pressure into the dust discharge cylinder, continuously sucking out the dust generated during drilling and preventing dust residue on the surface of the porous ceramic adsorption platform. This further improves the cleanliness during drilling and prevents dust from entering the pores of the porous ceramic adsorption platform.

Description

Technical Field

[0001] This invention belongs to the field of drilling equipment technology, and more specifically, it relates to a drilling equipment and a drilling method for a porous ceramic adsorption platform. Background Technology

[0002] A ceramic adsorption platform is an ultra-high precision process fixture based on the principle of vacuum adsorption. It is primarily made of high-purity advanced ceramics such as alumina and silicon carbide, and its adsorption surface features a uniform, interconnected microporous structure at the micrometer level. When connected to a vacuum system, these micropores form a stable and uniformly distributed negative pressure field, enabling the stable, damage-free, and deformation-free clamping of workpieces such as semiconductor wafers, glass substrates, and flexible films without mechanical contact or particulate contamination. Leveraging the inherent high rigidity, high flatness, wear resistance, corrosion resistance, low thermal expansion, and antistatic properties of ceramic materials, it is widely applicable to precision processes in high-end manufacturing, such as photolithography, grinding, cutting, inspection, and packaging. It is a core component ensuring processing accuracy and product yield. During the manufacturing process of the ceramic adsorption platform, drilling is required to facilitate installation and ensure the interconnection of the micropores.

[0003] Chinese Patent No. CN101143467B discloses a drilling device for slabs, including a machine bed, a worktable mounted on the machine bed, a frame connected to the machine bed, and a working head connected to the frame. The device achieves automated drilling of slabs through the cooperation of the machine bed, worktable, frame, and working head.

[0004] However, during the drilling process, ceramic adsorption platforms and stone slab-like workpieces are prone to generating large amounts of fine dust due to their brittleness. This dust not only causes environmental pollution, but more seriously, for porous media such as ceramic adsorption platforms, the flying dust can easily penetrate and remain in the micropore channels, causing pore blockage, resulting in a decrease in product yield and affecting subsequent vacuum adsorption performance. Summary of the Invention

[0011] Preferably, the opening and closing adjustment unit includes a ash discharge box, one end of which is connected to the upper ash discharge pipe and the lower ash discharge pipe, and the other end of which is provided with a ash discharge interface connected to an external negative pressure suction device. The ash discharge box is fixedly mounted with guide rails on the inner walls of one end of the upper and lower ash discharge pipes. A sealing plate, which is tightly sealed to the inner wall of the ash discharge box, is slidably installed inside the guide rails. The sealing plate is provided with upper and lower ash discharge holes that can respectively cooperate with the upper and lower ash discharge pipes. An elastic pressure member is installed on the top surface of the sealing plate. The bottom end of the sealing plate can slide to the bottom of the ash discharge box under the elastic pressure of the elastic pressure member. At this time, the upper ash discharge pipe and the upper ash discharge hole are staggered vertically so that the upper ash discharge hole is sealed by the sealing plate, while the lower ash discharge hole is located at one end of the lower ash discharge pipe to allow the lower ash discharge pipe to conduct. The sealing plate can also be retracted into the ash discharge box, and at this time, the upper ash discharge hole is located at one end of the upper ash discharge pipe to allow the upper ash discharge hole to conduct, while the lower ash discharge hole is staggered vertically so that the lower ash discharge pipe is sealed by the sealing plate.

An elastic sealing gasket is also installed on the connecting rod between the outer support frame and the inner limiting plate. The elastic sealing gasket can unfold and seal against the outer support frame, so that the elastic sealing gasket and the outer support frame cooperate to seal the intake port. The elastic sealing gasket can also bend and deform towards the inner limiting plate under the action of negative pressure suction, so that the intake port can be opened.

[0015] A drilling method for a porous ceramic adsorption platform, the specific steps of which are as follows: The porous ceramic adsorption platform is positioned and fixed on the positioning platform on the surface of the machine tool; The displacement drive unit first drives the drilling rig to move and adjust above the porous ceramic adsorption platform so that the drill bit at the bottom of the drilling rig is directly above the drilling position on the porous ceramic adsorption platform. The displacement drive unit drives the drill, drill bit and ash discharge cylinder to move downward synchronously, so that the drill bit and ash discharge cylinder abut against the surface of the porous ceramic adsorption platform; The drilling rig drives the drill bit to rotate and drill a hole. At this time, the displacement drive unit first drives the drilling rig and drill bit to move downward to drill a hole, and then drives the drilling rig and drill bit to move upward to reset. At the same time, the external negative pressure suction device draws negative pressure into the ash discharge cylinder through the guide section to suck out the dust generated by drilling. During the drilling process, the ash discharge cylinder is always in contact with the surface of the porous ceramic adsorption platform to seal and isolate the drilling location from the outside world. At the same time, the ash cleaning part moves up and down along the inner wall of the ash discharge cylinder to scrape off the dust adhering to the inner wall of the ash discharge cylinder and let it fall into the ash collection trough below. After the drilling is completed, the guide part guides the dust in the ash collection trough to be discharged.

[0016] Preferably, the drilling equipment can also be used to drill holes in clay bricks and tiles such as new sintered bricks and permeable bricks, as well as building blocks, and the dust can be recycled during drilling to prevent dust from scattering during drilling.

[0017] The present invention has the following beneficial effects: 1. In this invention, a dust discharge cylinder is movably mounted on the outer ring of the drill bit. During the drilling process, the dust discharge cylinder can always be in contact with the surface of the porous ceramic adsorption platform to seal and isolate the drilling position from the outside world, thereby preventing the dust generated during drilling from spreading outward and polluting the air or entering the pores of the porous ceramic adsorption platform. This is beneficial to improving the yield of the porous ceramic adsorption platform. Furthermore, the dust discharge cylinder is connected to an external negative pressure suction device through a guide section, allowing the external negative pressure suction device to draw negative pressure into the dust discharge cylinder through the guide section to continuously suck out the dust generated during drilling, preventing dust from remaining on the surface of the porous ceramic adsorption platform. This further improves the cleanliness during drilling and prevents dust from entering the pores of the porous ceramic adsorption platform.

[0018] 2. In this invention, the dust removal unit can move up and down along the inner wall of the dust discharge cylinder when the drilling rig is raising and lowering to drill, so that the dust removal unit can scrape off the dust adhering to the inner wall of the dust discharge cylinder. The scraped-off dust can be sucked out through the guide unit or fall into the dust collection trough below, thereby keeping the inner wall of the dust discharge cylinder clean and preventing dust from adhering to the inner wall of the dust discharge cylinder. When the dust discharge cylinder is adjusted by horizontal and vertical movement, it will drift downwards and fall onto the porous ceramic adsorption platform below, thereby further improving the cleanliness during drilling and preventing dust from entering the gaps of the porous ceramic adsorption platform during drilling.

[0019] 3. In this invention, the guide section is provided with a ash discharge outlet for drilling and a ash discharge outlet for dust in the dust collection trough. The two ash discharge outlets are adjusted by an opening and closing adjustment unit. The opening and closing adjustment unit can close the ash discharge outlet of the dust collection trough during drilling, thereby increasing the negative pressure airflow at the drilling guide ash discharge outlet to improve the ash discharge effect of the ash discharge cylinder during drilling. The opening and closing adjustment unit can also open only the ash discharge outlet of the dust collection trough after drilling is completed, thereby increasing the negative pressure airflow at the dust collection trough guide ash discharge outlet to improve the ash discharge effect of the dust in the dust collection trough.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example 1 Please see Figures 1-6 , Figure 10 As shown, this embodiment is a drilling device, including a machine tool 1. The machine tool 1 is equipped with a positioning platform for positioning the workpiece to be drilled. A drill rig 16 is also mounted on the machine tool 1 above the positioning platform via a displacement drive unit. A drill bit 19 is fixedly mounted on the output end of the drill rig 16. The displacement drive unit can drive the drill rig 16 to move up, down, and translate above the positioning platform. A dust discharge unit 2 is also mounted on the displacement drive unit. The dust discharge unit 2 includes a dust discharge cylinder 21, which is movably sleeved on the outer ring of the drill bit 19. The dust discharge cylinder 21 is provided with a guide section that can communicate with an external negative pressure suction device. The dust discharge cylinder 21 can... When the drill rig 16 is raised and lowered to drill, it moves up and down relative to the drill bit 19 so that the bottom end of the ash discharge cylinder 21 can always abut against the surface of the workpiece during the process of the drill bit 19 drilling into and out of the workpiece. The ash discharge section 2 also includes a ash cleaning section, which is fixedly installed on the bottom surface of the drill rig 16. The ash cleaning section can move up and down along the inner wall of the ash discharge cylinder 21 when the drill rig 16 is raised and lowered to drill, so that the ash cleaning section can scrape off the dust adhering to the inner wall of the ash discharge cylinder 21. The inner ring of the ash discharge cylinder 21 is provided with an ash collection groove 215 for receiving the scraped-off dust. The guide section can guide and discharge the dust in the ash collection groove 215 after drilling is completed.

[0027] When drilling is performed on the porous ceramic adsorption platform using this drilling equipment, the porous ceramic adsorption platform is positioned and fixed on the positioning platform on the surface of the machine tool 1. The displacement drive unit first drives the drilling machine 16 to move and adjust above the porous ceramic adsorption platform so that the drill bit 19 at the bottom of the drilling machine 16 is directly above the drilling position on the porous ceramic adsorption platform. The displacement drive unit then drives the drilling machine 16, the drill bit 19, and the ash discharge cylinder 21 to move downwards synchronously, so that the drill bit 19 and the ash discharge cylinder 21 abut against the surface of the porous ceramic adsorption platform. The drilling machine 16 drives the drill bit 19 to rotate and drill, at which time the displacement drive unit first drives the drill bit 19 to rotate and drill. The drill 16 and drill bit 19 descend to drill a hole, and then drive the drill 16 and drill bit 19 to move upward to reset. At the same time, the external negative pressure suction device draws negative pressure into the ash discharge cylinder 21 through the guide section to suck out the dust generated during drilling. During the drilling process, the ash discharge cylinder 21 is always in contact with the surface of the porous ceramic adsorption platform to seal and isolate the drilling position from the outside. At the same time, the dust removal part moves up and down along the inner wall of the ash discharge cylinder 21 to scrape off the dust adhering to the inner wall of the ash discharge cylinder 21 and let it fall into the ash collection trough 215 below. After the drilling is completed, the guide section guides and discharges the dust in the ash collection trough 215.

[0028] By incorporating a dust discharge cylinder 21 that moves movably around the outer ring of the drill bit 19, the dust discharge cylinder 21 can seal and isolate the drilling location from the outside environment during the drilling process, thereby preventing dust generated during drilling from spreading outwards and polluting the air or entering the pores of the porous ceramic adsorption platform. This, in turn, helps to improve the yield rate of the porous ceramic adsorption platform. Furthermore, the external negative pressure suction device can draw negative pressure into the dust discharge cylinder 21 through the guide section to continuously suck out the dust generated during drilling, preventing dust residue on the surface of the porous ceramic adsorption platform, further improving the cleanliness during drilling and effectively preventing dust from entering the pores of the porous ceramic adsorption platform. The cleaning section can scrape off the dust adhering to the inner wall of the ash discharge cylinder 21 during drilling. The scraped-off dust can be sucked out through the guide section or fall into the ash collection trough below, thereby keeping the inner wall of the ash discharge cylinder 21 clean and preventing dust from adhering to the inner wall of the ash discharge cylinder 21. When the ash discharge cylinder 21 is moved horizontally and vertically, it will drift downwards and fall onto the porous ceramic adsorption platform below, thereby further improving the cleanliness during drilling and preventing dust from entering the gaps of the porous ceramic adsorption platform during drilling. The guide section can also guide and discharge the dust in the ash collection trough 215 after drilling is completed, preventing dust from accumulating in the ash collection trough 215.

[0029] Example 2 Please see Figures 1-6As shown, the difference between this embodiment and the above embodiment is that the displacement drive unit includes a longitudinal adjustment slide rail 11, which is fixedly installed on the top surface of the machine tool 1 and located on the side of the positioning platform. The longitudinal adjustment slide rail 11 is equipped with a sliding bracket 12 and a translation drive component that can drive the sliding bracket 12 to slide and adjust. A transverse adjustment slide rail 13 is fixedly installed on the sliding bracket 12. A sliding seat 14 is equipped with a sliding drive component that can drive the sliding seat 14 to slide and adjust. A lifting seat 15 is equipped on the sliding seat 14 and a lifting drive component that can drive the lifting seat 15 to move up and down. The drilling rig 16 and the ash discharge unit 2 are both installed on the lifting seat 15. The translation drive uses a linear motor or a lead screw drive, while the lifting drive uses a hydraulic telescopic shaft. The linear motor, lead screw drive, and hydraulic telescopic shaft are all existing technologies and will not be described in detail. During drilling, the translation drive within the longitudinal adjusting slide rail 11 drives the sliding bracket 12 to translate longitudinally along the longitudinal adjusting slide rail 11. This causes the sliding bracket 12 to move longitudinally along the transverse adjusting slide rail 13, the sliding seat 14, the lifting seat 15, and the drilling rig 16. Simultaneously, the translation drive within the transverse adjusting slide rail 13 drives the sliding seat 14 to translate laterally along the transverse adjusting slide rail 13, causing the sliding seat 14 to move the lifting seat 15. The lifting seat 15 and the drilling rig 16 can be adjusted laterally and longitudinally to adjust their planar positions, so that they are directly above the drilling position. Then, the lifting drive on the sliding seat 14 drives the lifting seat 15 and the drilling rig 16 to move downward, so that the drill bit 19 at the bottom of the drilling rig 16 abuts against the porous ceramic adsorption platform below. The drilling rig 16 can then drive the drill bit 19 to rotate and drill. At the same time, the lifting seat 15 drives the dust discharge cylinder 21 to abut against the surface of the porous ceramic adsorption platform to isolate and remove the dust generated during drilling.

[0030] Furthermore, corrugated protective covers 17 are installed on both sides of the sliding bracket 12 at the opening of the longitudinal adjustment slide rail 11, and corrugated protective covers 17 are installed on both sides of the sliding seat 14 at the opening of the transverse adjustment slide rail 13. The corrugated protective covers 17 can protect the translation drive component inside the slide rail, preventing external dust from entering the translation drive component and causing contamination and jamming of the translation drive component.

[0031] Example 3 Please see Figures 1-4 , Figure 7 , Figure 8As shown, the difference between this embodiment and the above embodiment is that the drilling rig 16 is fixedly installed inside the lifting seat 15, and the lower end of the lifting seat 15 is provided with a sliding groove 18 located on the outer ring of the output end of the drilling rig 16; the upper end of the ash discharge cylinder 21 is slidably inserted into the sliding groove 18, and a positioning ring 212 is fixedly installed at the top of the ash discharge cylinder 21. An elastic telescopic member 211 that can apply downward elastic pressure to the ash discharge cylinder 21 is installed on the positioning ring 212; the elastic telescopic member 211 includes a pair of limiting guide shafts, which are circumferentially distributed and fixedly installed in the sliding groove 18, and all the limiting guide shafts are slidably inserted into the positioning ring 212. A pressure spring that abuts against the top surface of the positioning ring 212 is also fitted on the limiting guide shaft.

[0032] Initially, the ash discharge cylinder 21 is extended under the pressure of the pressure spring. At this time, the drill bit 19 is inside the ash discharge cylinder 21, and the bottom end of the drill bit 19 is flush with the bottom end of the ash discharge cylinder 21. During drilling, the drill bit 19 and the ash discharge cylinder 21 move downward under the drive of the lifting seat and abut against the surface of the porous ceramic adsorption platform. Then, the lifting seat 15 drives the drill bit 19 to move downward to drill, while the ash discharge cylinder 21 slides upward along the slide groove 18 under the abutment and limiting action of the porous ceramic adsorption platform. At this time, the ash discharge cylinder 21 moves upward relative to the lifting seat 15 and the drill bit 19. When drilling... When the lifting seat 15 moves upward, it drives the drill bit 19 upward, gradually pulling the drill bit 19 out of the borehole. During this process, the ash discharge cylinder 21 slides down and resets along the slide groove 18 under the drive of the pressure spring, so that the ash discharge cylinder 21 always abuts and seals against the surface of the porous ceramic adsorption platform during the resetting and pulling out of the drill bit 19, until the drill bit 19 moves to the outside of the borehole. At this time, the ash discharge cylinder 21 completes the sliding reset. Then, as the lifting seat 15 moves upward, the lifting seat 15 drives the ash discharge cylinder 21 and the drill bit 19 to move upward synchronously, thereby completing the drilling process. By limiting the downward movement of the elastic telescopic component 211, the ash discharge cylinder 21 can be sealed against the surface of the porous ceramic adsorption platform when the drill bit 19 is drilling downwards and exiting the hole upwards, thereby sealing and isolating the drilling position from the outside world during the drilling process and preventing the dust generated during drilling from spreading everywhere.

[0033] Example 4 Please see Figures 1-4 , Figures 9-14As shown, the difference between this embodiment and the above embodiment is that the guide section includes a ash discharge hood 26, a guide ring 29, and an opening / closing adjustment unit. The ash discharge hood 26 is connected and installed on the side wall of the ash discharge cylinder 21, and an upper ash discharge pipe 217 is connected and installed at one end of the ash discharge hood 26. The guide ring 29 is fixedly installed on the outer ring of the lower end of the ash discharge cylinder 21, and the guide ring 29 and the ash collection trough 215 are connected through multiple ash discharge holes 216 provided on the side wall of the ash discharge cylinder 21. A lower ash discharge pipe 218 is connected and installed on the outer side of the guide ring 29. Both the upper ash discharge pipe 217 and the lower ash discharge pipe 218 can be connected to an external negative pressure suction device through the opening / closing adjustment unit, and the opening / closing adjustment unit can open the upper ash discharge pipe 217 when drilling, at which time the upper ash discharge pipe 217 discharges ash. The hood 26 draws negative pressure into the ash discharge cylinder 21 so that the dust in the ash discharge cylinder 21 can be discharged outward through the ash discharge hood 26 and the upper ash discharge pipe 217, while the lower ash discharge pipe 218 is closed. This ensures that only one negative pressure source remains on the ash discharge cylinder 21, which not only improves the negative pressure suction during ash discharge but also prevents mutual interference between the two negative pressure sources, thereby improving the negative pressure suction ash discharge effect. The opening and closing adjustment unit can also close the upper ash discharge pipe 217 and open the lower ash discharge pipe 218 after drilling is completed. At this time, the lower ash discharge pipe 218 draws negative pressure into the ash collection trough 215 through the guide ring 29 and multiple ash discharge holes 216 to draw out the dust collected in the ash collection trough 215, preventing the dust from continuously accumulating in the ash collection trough 215 and causing excessive dust accumulation and outward dispersion.

[0034] Specifically, the opening and closing adjustment unit includes a dust discharge box 27. One end of the dust discharge box 27 is connected to the upper dust discharge pipe 217 and the lower dust discharge pipe 218, and the other end of the dust discharge box 27 is provided with a dust discharge interface connected to an external negative pressure suction device. A guide rail 220 is fixedly installed on the inner wall of the dust discharge box 27 at one end of the upper dust discharge pipe 217 and the lower dust discharge pipe 218. A sealing plate 219 is slidably installed in the guide rail 220 and is tightly sealed to the inner wall of the dust discharge box 27. The sealing plate 219 is provided with an upper dust discharge hole 222 and a lower dust discharge hole 221 that can cooperate with the upper dust discharge pipe 217 and the lower dust discharge pipe 218, respectively. An elastic pressure member 223 is installed on the top surface of the sealing plate 219. The bottom end of 219 can slide to extend below the ash discharge box 27 under the elastic pressure of the elastic pressure member 223. At this time, the upper ash discharge pipe 217 and the upper ash discharge hole 222 are staggered vertically so that the upper ash discharge hole 222 is sealed by the sealing plate 219. The lower ash discharge hole 221 is located at one end of the lower ash discharge pipe 218 so that the lower ash discharge pipe 218 is open. The sealing plate 219 can also be retracted into the ash discharge box 27. At this time, the upper ash discharge hole 222 is located at one end of the upper ash discharge pipe 217 so that the upper ash discharge hole 222 is open. The lower ash discharge hole 221 and the lower ash discharge pipe 218 are staggered vertically so that the lower ash discharge pipe 218 is sealed by the sealing plate 219.

[0035] During drilling, when the ash discharge cylinder 21 abuts against the surface of the porous ceramic adsorption platform for ash discharge, the bottom end of the sealing plate 219 abuts against the surface of the porous ceramic adsorption platform, causing the sealing plate 219 to be retracted into the ash discharge box 27. At this time, the upper ash discharge hole 222 is located at one end of the upper ash discharge pipe 217, so that the upper ash discharge hole 222 is open. The lower ash discharge hole 221 is staggered from the lower ash discharge pipe 218, so that the lower ash discharge pipe 218 is sealed by the sealing plate 219. Thus, the dust in the ash discharge cylinder 21 is discharged outward through the ash discharge hood 26, the upper ash discharge pipe 217, and the ash discharge box 27. When drilling is completed... When the ash discharge cylinder 21 rises and separates from the surface of the porous ceramic adsorption platform, the sealing plate 219 slides down and resets under the elastic pressure of the elastic pressure member 223 (the elastic pressure member 223 is preferably an elastic telescopic shaft). At this time, the upper ash discharge pipe 217 and the upper ash discharge hole 222 are staggered so that the upper ash discharge hole 222 is sealed by the sealing plate 219, while the lower ash discharge hole 221 is located at one end of the lower ash discharge pipe 218 so that the lower ash discharge pipe 218 is open, thereby allowing the dust in the ash collection trough 215 to be discharged outward through the ash discharge hole 216, the guide ring 29, the lower ash discharge pipe 218 and the ash discharge box 27. The automatic lifting and lowering adjustment of the sealing plate 219 allows for the automatic opening and closing of the two ash discharge channels during drilling. When drilling, the ash discharge channel connected to the ash discharge cylinder 21 automatically opens to discharge the dust generated during drilling. After drilling is completed, the ash discharge channel connected to the ash collection trough 215 opens to discharge the dust in the ash collection trough 215, preventing dust from accumulating in the ash collection trough 215.

[0036] Example 5 Please see Figures 1-4 , Figure 7 As shown, the difference between this embodiment and the above embodiment is that the ash discharge interface includes a positioning seat 22, which is fixedly connected to the top end of the ash discharge cylinder 21, and the positioning seat 22 is slidably assembled on the surface of the lifting seat 15. A negative pressure interface 24 and an ash discharge conduit 25 communicating with the negative pressure interface 24 are installed on the positioning seat 22, and one end of the ash discharge conduit 25 is communicating with the ash discharge box 27. A positioning bolt 23 is also installed on the positioning seat 22, which can abut against the surface of the lifting seat 15 to lock the positioning seat 22 on the lifting seat 15.

[0037] The negative pressure interface 24 is connected to an external negative pressure suction device (preferably a bag filter with a negative pressure fan, which can draw dust into the bag filter and then filter it) through a hose. This allows the negative pressure suction device to draw negative pressure into the ash discharge box 27 through the negative pressure interface 24 and the hose, so that the ash discharge box 27 can draw dust out of the ash discharge cylinder 21. The positioning seat 22 can slide up and down along the lifting seat 15 during the drilling and ash discharge process to assist in positioning the ash discharge cylinder 21 and improve the stability of the lifting and lowering operation of the ash discharge cylinder 21. When it is necessary to replace the drill bit 19, the ash discharge cylinder 21 and the positioning seat 22 can be pushed up and slid to expose the drill bit 19 in the inner ring of the ash discharge cylinder 21. Then, the positioning bolt 23 is tightened to lock the positioning seat 22 on the lifting seat 15, thereby locking the ash discharge cylinder 21 and facilitating the subsequent disassembly and replacement of the drill bit 19.

[0038] Example 6 Please see Figure 5 , Figure 6 , Figure 9 , Figure 10 , Figure 15 As shown, the difference between this embodiment and the above embodiment is that the ash removal part includes a positioning frame 213 and a scraper ring 210. The positioning frame 213 is fixedly installed at the bottom end of the drilling rig 16, and the scraper ring 210 is disposed below the positioning frame 213. The scraper ring 210 and the positioning frame 213 are fixedly connected by a plurality of positioning strips 214 distributed in a circle. At the same time, the scraper ring 210 slides and fits tightly against the inner wall of the ash discharge cylinder 21. During the drilling process, when the ash discharge cylinder 21 moves up and down relative to the drilling rig 16, the drilling rig 16 drives the scraper ring 210 to move up and down synchronously on the inner wall of the ash discharge cylinder 21 through the positioning frame 213 and the positioning strip 214. At this time, the scraper ring 210 can scrape off the dust adhering to the inner wall of the ash discharge cylinder 21. After that, the scraped dust is sucked out from the ash discharge hood 26 or falls down into the ash collection trough 215 below, and is sucked out from the ash discharge hole 216 after the drilling is completed.

[0039] Example 7 Please see Figure 8 , Figure 10 , Figure 16 As shown, the difference between this embodiment and the above embodiment is that a sealing gasket is fixedly installed at the bottom of the ash discharge cylinder 21. When the ash discharge cylinder 21 abuts against the surface of the porous ceramic adsorption platform, it can improve the sealing performance of the connection between the ash discharge cylinder 21 and the porous ceramic adsorption platform, preventing dust from drifting outward from the joint. At the same time, multiple air inlets are provided on the side wall of the ash discharge cylinder 21, and one-way air inlet valves 28 are installed in the air inlets. When the negative pressure suction device sucks and discharges ash from the ash discharge cylinder 21, it can unidirectionally introduce air through the air inlets and one-way air inlet valves 28, so as to keep the airflow flowing in the ash discharge cylinder 21, thereby improving the suction and ash discharge effect.

[0040] Specifically, the one-way intake valve 28 includes an outer support frame 2801, which is fixedly installed inside the intake port. A connecting rod 2803 is inserted into the outer support frame 2801. An outer limiting plate 2804 is fixedly installed on the outer end of the connecting rod 2803, abutting against the outer surface of the outer support frame 2801. An inner limiting plate 2805 is fixedly installed on the inner end of the connecting rod 2803. An elastic sealing gasket 2802 is also installed on the connecting rod 2803 between the outer support frame 2801 and the inner limiting plate 2805. The elastic sealing gasket 2802 can unfold and seal against the outer support frame 2801, so that the elastic sealing gasket 2802 and the outer support frame 2801 cooperate to seal the intake port. The elastic sealing gasket 2802 can also bend and deform towards the inner limiting plate 2805 under the action of negative pressure suction, so that the intake port opens. When no negative pressure is formed inside the ash discharge cylinder 21, the elastic sealing gasket 2802 can unfold and seal against the outer support frame 2801 under its own elasticity, thereby sealing the air inlet. When a negative pressure is formed inside the ash discharge cylinder 21, the elastic sealing gasket 2802 bends and deforms towards the inner limiting plate 2805 under the action of negative pressure suction, so that the air inlet opens. At this time, air enters the ash discharge cylinder 21 while ash is being drawn out, thereby keeping the airflow inside the ash discharge cylinder 21 in one direction to achieve unidirectional ash discharge.

[0041] Example 8 This embodiment discloses a drilling method for a porous ceramic adsorption platform, the specific steps of which are as follows: The porous ceramic adsorption platform is positioned and fixed on the positioning platform on the surface of machine tool 1; The displacement drive unit first drives the drill 16 to move and adjust above the porous ceramic adsorption platform so that the drill bit 19 at the bottom of the drill 16 is directly above the drilling position on the porous ceramic adsorption platform. The displacement drive unit drives the drill 16, drill bit 19 and ash discharge cylinder 21 to move down synchronously, so that the drill bit 19 and ash discharge cylinder 21 abut against the surface of the porous ceramic adsorption platform. The drill rig 16 drives the drill bit 19 to rotate and drill. At this time, the displacement drive unit first drives the drill rig 16 and the drill bit 19 to descend and drill, and then drives the drill rig 16 and the drill bit 19 to move upward and reset. At the same time, the external negative pressure suction device draws negative pressure into the ash discharge cylinder 21 through the guide section to suck out the dust generated by drilling. During the drilling process of the drilling rig 16 and the drill bit 19, the ash discharge cylinder 21 is always in contact with the surface of the porous ceramic adsorption platform to seal and isolate the drilling position from the outside. At the same time, the ash cleaning part moves up and down along the inner wall of the ash discharge cylinder 21 to scrape off the dust adhering to the inner wall of the ash discharge cylinder 21 and let it fall into the ash collection trough 215 below. After the drilling is completed, the guide part guides the dust in the ash collection trough 215 to be discharged.
