Abstract
Description
Technical Field
[0001] This invention relates to the field of drilling lathe technology, specifically a drilling lathe for machining one-way valves and two-way valves. Background Technology
[0002] As a core component in fluid control, the machining accuracy of the dual-valve structure of the check valve directly affects its sealing performance and service life. Drilling is a critical process in the machining of the dual-valve structure of the check valve, which requires a dedicated drilling lathe. During the drilling process of the dual-valve check valve, in order to reduce machining temperature, minimize tool wear, and improve drilling accuracy, it is usually necessary to continuously spray a large amount of coolant and cutting fluid to cool and lubricate the tool and the workpiece.
[0003] Most existing drilling lathes lack dedicated coolant recovery structures. After processing, the coolant, mixed with metal shavings, is directly discharged, resulting in significant coolant waste, increased material costs, and environmental pollution – contrary to the industry trend of green manufacturing. While some drilling lathes have simple filtration and recovery devices, their designs are flawed. The filter orifice diameters are not tailored to the size of the machining debris, and they lack effective debris removal mechanisms. This causes metal shavings to accumulate on the filter surface, quickly clogging the orifices and preventing coolant from passing through for recovery. This interruption of coolant recovery necessitates frequent machine stops for cleaning, disrupting drilling continuity, increasing operator workload, and preventing proper coolant circulation, indirectly affecting machining accuracy and tool life. Summary of the Invention

[0009] Preferably, the clamping mechanism includes an electric push rod and a telescopic rod.

[0015] This invention provides a drilling lathe for machining one-way and two-way valves. It has the following advantages: 1. This invention, by installing a filter plate inside the worktable, effectively separates drilling debris from coolant and cutting fluid. The filtered coolant can flow into a recycling tank for reuse, significantly reducing processing costs and environmental pollution. Simultaneously, the drive mechanism causes a scraper to slide back and forth along the surface of the filter plate, promptly pushing accumulated debris to both sides. Combined with the bidirectional scraping design driven by forward and reverse lead screws, this effectively prevents debris from clogging the filter holes, ensuring that coolant and cutting fluid remain unobstructed, thereby guaranteeing continuous and stable drilling operations over extended periods.
[0016] 2. This invention, by setting rotary motors and corresponding active and passive clamping plates on both sides of the worktable, enables the clamped workpiece to rotate freely, achieving multi-point and multi-angle drilling operations and significantly improving processing efficiency. When one side of the drilling mechanism malfunctions, the workpiece can be quickly switched to a backup drilling position on the other side via the rotary motor, allowing processing to continue using the other side's drilling mechanism. This avoids production interruptions caused by downtime for maintenance and significantly reduces losses due to equipment failure.
[0017] 3. This invention utilizes the reciprocating motion of the sliding frame to drive the piston cylinder to generate compressed gas. The gas is then precisely sprayed onto the surface of the workpiece and the interior of the drilled hole through a high-pressure nozzle of the cleaning mechanism. Combined with a rotary motor that lifts the workpiece, the high-speed airflow penetrates deep into the drilled hole, thoroughly blowing out residual debris and coolant, preventing debris residue from affecting subsequent assembly or usage accuracy.
[0018] 4. This invention uses a symmetrical inclined structure of the guide plate to concentrate debris and coolant towards the filter plate. Furthermore, the cooperation of the upper limiting plate, lower limiting plate, telescopic plate, and side plates compresses the loose debris into blocks as the scraper pushes it to the end of its stroke, facilitating subsequent storage and processing and reducing the space occupied by the debris. Simultaneously, the partition inside the worktable effectively isolates the drive mechanism from contact with debris and coolant, preventing corrosion and jamming. Attached Figure Description

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Please see the appendix Figure 1 -Appendix Figure 10 This invention provides a drilling lathe for machining one-way valves and two-way valves, including a worktable 1, a drilling mechanism 2 installed on the outer wall of the worktable 1, a filter plate 3 fixedly installed inside the worktable 1, a partition 4 fixedly connected inside the worktable 1, a drive mechanism 5 provided inside the worktable 1, two sets of sliding frames 6 connected to the drive mechanism 5, a scraper 7 fixedly connected to the outer wall of the sliding frame 6, the drive mechanism 5 and the scraper 7 are respectively located on both sides of the partition 4, and the lower surface of the scraper 7 is slidably connected to the upper surface of the filter plate 3.
[0023] Specifically, the drilling lathe includes a worktable 1, which serves as the mounting base and support platform for the entire equipment, capable of withstanding the vibrations and impacts generated during drilling. A drilling mechanism 2 is installed on the outer wall of the worktable 1. The drilling mechanism 2 is the core actuator for drilling operations on one-way and two-way valve workpieces. A filter plate 3 is fixedly installed inside the worktable 1. The filter plate 3 is horizontally laid in a pre-set mounting groove inside the worktable 1, with finely distributed filter holes on its surface. The diameter of the filter holes is designed according to the particle size of the chips generated during processing, ensuring effective chip interception while allowing coolant and cutting fluid to pass through smoothly. A partition 4 is fixedly connected inside the worktable 1, vertically fixed inside the worktable 1, dividing the interior of the worktable 1 into two independent areas. These areas are used to install the drive mechanism 5 and to house the scraper 7, respectively, isolating the drive component from the chip handling component and preventing chips from entering the drive mechanism 5 and affecting its normal operation. The workbench 1 is internally equipped with a drive mechanism 5, which serves as the power output component, providing stable power for the sliding of the scraper 7. The drive mechanism 5 is connected to two sets of sliding frames 6, symmetrically arranged on one side of the partition 4, and are connected to the power output end of the drive mechanism 5, allowing them to slide back and forth in a preset direction under the drive of the drive mechanism 5. A scraper 7 is fixedly connected to the outer wall of the sliding frame 6. The scraper 7 is made of wear-resistant rubber, and its lower surface is in close contact with the upper surface of the filter plate 3, ensuring that the scraper 7 can fully contact the surface of the filter plate 3 during sliding, thoroughly scraping away the accumulated debris on the filter plate 3. The drive mechanism 5 and the scraper 7 are located on opposite sides of the partition 4. This layout effectively prevents the drive mechanism 5 from contacting debris and coolant, preventing rust, jamming, and other malfunctions. In actual machining, the drilling mechanism 2 is used to drill one-way valve / double-valve workpieces. Because drilling generates a large amount of heat, a large amount of coolant and cutting fluid is typically used to reduce machining temperature, minimize tool wear, and improve drilling accuracy. Simultaneously, drilling produces a large amount of metal debris, which, mixed with coolant and cutting fluid, falls onto the filter plate 3 of the worktable 1. The filter plate 3 filters the mixture, trapping the metal debris. The filtered coolant and cutting fluid then flow smoothly into a recycling tank located below the filter plate 3 inside the worktable 1, achieving the recycling and reuse of coolant and cutting fluid, reducing machining costs, and preventing coolant waste and environmental pollution. At the same time, after the drive mechanism 5 is started, it will drive the two sets of sliding frames 6 to slide synchronously. The sliding frames 6 will drive the scraper 7 to slide back and forth along the surface of the filter plate 3. During the sliding process, the scraper 7 can push the debris accumulated on the filter plate 3 to both sides of the worktable 1, so as to avoid excessive accumulation of debris on the surface of the filter plate 3, which will cause the filter holes to be blocked, and ensure the normal flow of coolant and cutting fluid, and ensure the continuous drilling process.
[0024] The drilling mechanism 2 includes a three-axis gimbal 201, the outer wall of which is fixedly installed on the outer wall of the worktable 1, and a drilling rig 202 is fixedly installed on the outer wall of the three-axis gimbal 201.
[0025] Specifically, the drilling mechanism 2 includes a three-axis gimbal 201. The three-axis gimbal 201 serves as the adjustment component of the drilling mechanism 2. Its outer wall is fixedly mounted on a pre-set mounting base on the outer wall of the worktable 1 using bolts. The mounting base is integrally formed with the worktable 1, ensuring the stability of the three-axis gimbal 201. The three-axis gimbal 201 adopts an existing mature three-axis adjustment structure, enabling free adjustment in three directions: forward / backward, left / right, and up / down. It also has an angle adjustment function, and its adjustment accuracy meets the precision requirements of drilling for both check valves and double valves. A drilling rig 202 is fixedly mounted on the outer wall of the three-axis gimbal 201. The drilling rig 202 is fixedly connected to the execution end of the three-axis gimbal 201 using bolts, and its position and angle are adjusted according to the adjustment of the three-axis gimbal 201. The drilling rig 202 is equipped with dedicated drilling tools. The model and specifications of the tools are adapted to the drilling size of the check valve and double valve, enabling drilling. In actual processing, the operator can adjust the position and angle of the drilling machine 202 by controlling the adjustment button of the three-axis gimbal 201 according to the drilling position requirements of the one-way valve and the double valve workpiece. This allows the drill 202 to be aligned with the drilling point of the workpiece. After adjustment, the drill 202 is started, and the drill 202 drives the drill to rotate at high speed to perform drilling operations on the workpiece. This achieves drilling requirements at different positions and angles, adapting to the complex processing requirements of one-way valves and double valves.
[0026] The drive mechanism 5 includes a drive motor 501 and a slide rod 503. The outer wall of the drive motor 501 is fixedly installed inside the worktable 1. The output end of the drive motor 501 is fixedly connected to a positive and negative lead screw 502. The outer wall of the positive and negative lead screw 502 is rotatably connected inside the worktable 1. The outer wall of the positive and negative lead screw 502 is threadedly connected to a sliding frame 6. The two ends of the slide rod 503 are fixedly connected inside the worktable 1. The outer wall of the slide rod 503 is slidably connected to the sliding frame 6.
[0027] Specifically, the drive mechanism 5 includes a drive motor 501 and a slide bar 503. The drive motor 501 serves as the power source for the drive mechanism 5, and its outer wall is fixedly mounted inside the worktable 1 via a motor mounting bracket. The motor mounting bracket is welded and fixed to the inner wall of the worktable 1 to ensure that the drive motor 501 will not shake during operation. The drive motor 501 can adjust its output speed according to the accumulation of debris, thereby controlling the sliding speed of the scraper 7 and achieving efficient debris cleaning. The output end of the drive motor 501 is fixedly connected to a positive and negative lead screw 502 via a coupling. The positive and negative lead screw 502 is horizontally set inside the worktable 1, and its two ends are rotatably connected to the pre-set bearing seats on the inner wall of the worktable 1 via bearings, ensuring that the positive and negative lead screw 502 can rotate flexibly and reducing friction during rotation. The outer wall of the positive and negative lead screw 502 is threadedly connected to the sliding frame 6. The two sides of the positive and negative lead screw 502 are provided with threads in opposite directions. Two sets of sliding frames 6 are threadedly connected to the threaded sections on both sides of the positive and negative lead screw 502. This design allows the two sets of sliding frames 6 to slide synchronously in opposite directions when the positive and negative lead screw 502 rotates. The two ends of the slide rod 503 are fixedly connected to the inside of the worktable 1 by bolts. The slide rod 503 is arranged parallel to the positive and negative lead screw 502, and its outer wall is slidably connected to the sliding frame 6. The slide rod 503 also serves as a guide and support for the sliding frame 6, ensuring that the sliding frame 6 does not shift or tilt during sliding, and ensuring that the scraper 7 can smoothly slide against the surface of the filter plate 3. In actual operation, after the drive motor 501 starts, its output end drives the positive and negative lead screws 502 to rotate at a constant speed. Since the threads on both sides of the positive and negative lead screws 502 rotate in opposite directions, the two sets of sliding frames 6 will slide in opposite directions along the guide direction of the slide rod 503 under the action of the threads. The sliding frames 6 drive the scraper 7 to slide synchronously, thereby realizing bidirectional scraping of debris on the surface of the filter plate 3, improving the debris cleaning efficiency, and preventing debris from accumulating in the middle of the filter plate 3.
[0028] Rotary motors 9 are fixedly connected to both outer walls of the workbench 1. A passive clamping plate 12 is fixedly connected to one side of the rotary motor 9, and a clamping mechanism 10 is fixedly connected to the other side of the rotary motor 9. The clamping mechanism 10 is connected to an active clamping plate 11.
[0029] Specifically, rotary motors 9 are fixedly connected to both outer walls of the worktable 1. The rotary motors 9 are fixedly mounted on the outer walls of the worktable 1 via brackets and welded to the outer walls to ensure the robustness of the installation and to align the output end of the rotary motor 9 with the central axis of the workpiece. A passive clamping plate 12 is fixedly connected to the output end of one rotary motor 9 via a coupling. The passive clamping plate 12 has a circular structure and its surface is polished to ensure a tight fit when in contact with the workpiece. A clamping mechanism 10 is fixedly connected to the output end of the other rotary motor 9 via a coupling. An active clamping plate 11 is connected to the output end of the clamping mechanism 10. The active clamping plate 11 and the passive clamping plate 12 have the same structure and are symmetrically arranged, working together to clamp and fix the one-way valve / dual-valve workpiece. In actual processing, the rotary motor 9 drives the passive clamping plate 12 and the active clamping plate 11 to rotate synchronously, thereby rotating the workpiece held between them. This allows for adjustment of the workpiece's angle, enabling the drilling mechanism 2 to drill at different positions on the workpiece. Multi-point drilling can be completed without disassembling the workpiece, improving processing efficiency. Furthermore, if one side of the drilling mechanism 2 malfunctions, there is no need to stop for repairs. The rotary motor 9 can be controlled to rotate the active clamping plate 11, the passive clamping plate 12, and the workpiece as a whole, switching the workpiece to a backup drilling position on the other side. The drilling mechanism 2 on the other side can then continue processing, ensuring continuity and minimizing downtime. Additionally, during drilling, the rotary motor 9 can also lift the workpiece and sway it left and right, using centrifugal force and gravity to remove residual debris from the drilled holes, preventing debris from affecting drilling accuracy and processing quality.
[0030] The clamping mechanism 10 includes an electric push rod 1001 and a telescopic rod 1002. The outer wall of the electric push rod 1001 and one end of the telescopic rod 1002 are both fixedly connected to the outer wall of the rotary motor 9. The output end of the electric push rod 1001 and the other end of the telescopic rod 1002 are both fixedly connected to the outer wall of the active clamping plate 11.
[0031] Specifically, the clamping mechanism 10 includes an electric push rod 1001 and a telescopic rod 1002. The electric push rod 1001 serves as the power component of the clamping mechanism 10, and its outer wall is fixedly connected to the outer wall of the rotary motor 9 via a mounting bracket. The mounting bracket is welded and fixed to the housing of the rotary motor 9 to ensure stable installation of the electric push rod 1001. One end of the telescopic rod 1002 is fixedly connected to the outer wall of the rotary motor 9 by bolts, and is symmetrically arranged with the electric push rod 1001. The telescopic rod 1002 adopts a telescopic structure, which has good telescopic flexibility and support stability. The output end of the electric push rod 1001 and the other end of the telescopic rod 1002 are both fixedly connected to the outer wall of the active clamping plate 11 by bolts. The output end of the electric push rod 1001 is aligned with the center position of the active clamping plate 11, and the telescopic rods 1002 are symmetrically distributed on both sides of the electric push rod 1001 to ensure that the active clamping plate 11 is subjected to uniform force and to avoid tilting during the clamping process. In actual clamping operations, when it is necessary to clamp a one-way valve or dual-valve workpiece, the electric push rod 1001 is activated. The output end of the electric push rod 1001 extends, driving the active clamping plate 11 to move towards the passive clamping plate 12. The telescopic rod 1002 extends synchronously, providing guidance and support for the active clamping plate 11 and preventing it from shifting during movement. When the active clamping plate 11 contacts the workpiece surface and reaches the preset clamping force, the electric push rod 1001 stops operating. At this time, the active clamping plate 11 and the passive clamping plate 12 cooperate to firmly clamp the workpiece between them. The clamping force can be adjusted through the control module of the electric push rod 1001 to adapt to one-way valves or dual-valve workpieces of different sizes and materials, avoiding damage to the workpiece due to excessive clamping force or shaking of the workpiece during drilling due to insufficient clamping force, which would affect the machining accuracy. Once the machining is complete, the output end of the electric push rod 1001 retracts, causing the active clamping plate 11 to move away from the passive clamping plate 12, and the telescopic rod 1002 retracts synchronously, allowing the machined workpiece to be removed.
[0032] A guide plate 8 is fixedly connected to the outer wall of the workbench 1. The guide plate 8 is located below the clamping mechanism 10, and the upper surface of the guide plate 8 is symmetrically inclined.
[0033] Specifically, a guide plate 8 is fixedly connected to the outer wall of the workbench 1. The guide plate 8 is bolted to the outer wall of the workbench 1 and is located below the clamping mechanism 10, ensuring that the debris and coolant generated during drilling can fall smoothly onto the guide plate 8. The guide plate 8 is made of stainless steel and its surface is polished to reduce the adhesion of debris and coolant to its surface. The upper surface of the guide plate 8 has a symmetrical inclined structure, with the inclined direction facing both sides of the workbench 1. The inclination angle is designed according to actual usage requirements to ensure that debris and coolant can flow to both sides along the inclined surface under the action of gravity. During actual processing, when the drilling mechanism 2 drills the workpiece, the generated debris and sprayed coolant fall onto the guide plate 8 below. Since the surface of the guide plate 8 is symmetrically inclined, the debris and coolant flow along the inclined surface to both sides of the worktable 1, and are finally guided to the filter plates 3 on both sides of the worktable 1. This achieves centralized collection and filtration of debris and coolant, preventing debris and coolant from scattering outside the worktable 1. At the same time, it ensures that the filter plates 3 can completely intercept debris, improve the coolant recovery efficiency, and keep the surrounding environment of the worktable 1 clean.
[0034] The outer wall of the scraper 7 is fixedly connected to an upper limiting plate 14, and the lower outer wall of the sliding frame 6 is fixedly connected to a lower limiting plate 15. The lower limiting plate 15 is located below the filter plate 3. One end of a spring 16 is fixedly connected inside both the upper limiting plate 14 and the lower limiting plate 15. The other end of the spring 16 is fixedly connected to a telescopic plate 17. The outer wall of the telescopic plate 17 is slidably connected to the inside of the upper limiting plate 14 or the lower limiting plate 15. The inside of the workbench 1 is fixedly connected to a partition plate 18, and the outer wall of the workbench 1 is fixedly connected to a side plate 13. The outer wall of the telescopic plate 17 can fit against the outer wall of the side plate 13.
[0035] Specifically, an upper limiting plate 14 is fixedly connected to the outer wall of the scraper 7. The upper limiting plate 14 is vertically welded to the top outer wall of the scraper 7 and is distributed perpendicularly to the scraper 7. Its length is the same as the length of the scraper 7, ensuring that the top area of the scraper 7 is fully covered. A lower limiting plate 15 is fixedly connected to the lower outer wall of the sliding frame 6. The lower limiting plate 15 is vertically welded to the bottom outer wall of the sliding frame 6 and is distributed perpendicularly to the sliding frame 6. Its length is the same as the length of the sliding frame 6. The lower limiting plate 15 is located below the filter plate 3 and is symmetrically arranged with the upper limiting plate 14. Both the upper limiting plate 14 and the lower limiting plate 15 have telescopic grooves inside. One end of a spring 16 is fixedly connected inside the telescopic groove. The spring 16 is a compression spring. The other end of the spring 16 is fixedly connected to a telescopic plate 17. The outer wall of the telescopic plate 17 is tightly fitted to the inner wall of the telescopic groove, allowing it to slide freely inside the telescopic groove. The end of the telescopic plate 17 extends outside the telescopic groove, and its extension length can be adjusted according to the extension and contraction of the spring 16. A partition 18 is fixedly connected inside the workbench 1. The partition 18 is vertically fixed inside the workbench 1, located on both sides of the filter plate 3, and welded to the inner wall of the workbench 1 to separate the debris collection area from other areas. Side plates 13 are fixedly connected to the outer wall of the workbench 1. The side plates 13 are vertically welded to the outer walls of both sides of the workbench 1, located at the ends of the filter plate 3, and cooperate with the partition 18 to form a debris collection channel. The outer wall of the telescopic plate 17 can fit against the outer wall of the side plate 13. When the scraper 7 drives the upper limiting plate 14 and the lower limiting plate 15 to move towards the side plate 13, the telescopic plate 17 will first contact the side plate 13. During the actual debris removal process, the scraper 7 slides towards both sides of the worktable 1 under the drive of the sliding frame 6, simultaneously moving the upper limiting plate 14 and the lower limiting plate 15. As the scraper 7 moves, the debris on the filter plate 3 is gradually pushed towards the side plate 13. When the telescopic plate 17 contacts the side plate 13, the continuing movement of the upper limiting plate 14 and the lower limiting plate 15 will compress the spring 16. The spring 16 is compressed, and the telescopic plate 17 gradually retracts into the telescopic groove of the upper limiting plate 14 and the lower limiting plate 15. During this process, the debris pushed towards the side plate 13 is compressed by the upper limiting plate 14, the lower limiting plate 15, the telescopic plate 17, and the side plate 13, compressing the originally loose debris into smaller blocks for easier subsequent storage and processing. When the scraper 7 reaches its maximum stroke, the drive mechanism 5 drives the scraper 7 to move in the opposite direction. At this time, the spring 16 is no longer compressed and resets under the action of elastic force, pushing the telescopic plate 17 out of the telescopic groove and returning to its initial position. The compressed debris falls into the debris boxes located on both sides of the partition 18 inside the workbench 1 under its own gravity, achieving centralized collection of debris. To ensure that the telescopic plate 17 can extend and retract normally and avoid jamming, the outer wall of the telescopic plate 17 is provided with an anti-slip and blocking structure in the prior art. This structure can be achieved by opening guide grooves on the surface of the telescopic plate 17 and setting guide blocks on the inner wall of the telescopic grooves to ensure smooth sliding of the telescopic plate 17.Meanwhile, the upper surfaces of the lower limiting plate 15 and the telescopic plate 17 inside it are both set as inclined structures, with the inclined direction facing the debris box, to further guide the debris to fall smoothly into the debris box under its own weight, and avoid the debris from accumulating on the surface of the limiting plate.
[0036] Two sets of piston cylinders 19 are fixedly connected to the outer wall of the partition 2 18. A piston head 22 is slidably connected inside the piston cylinder 19. One end of a piston rod 21 is fixedly connected to the outer wall of the piston head 22. A connecting plate 20 is fixedly connected to the other end of the piston rod 21. The outer wall of the connecting plate 20 is fixedly connected to the lower surface of the sliding frame 6. A cleaning mechanism 25 is provided on the outer wall of the piston cylinder 19.
[0037] Specifically, two sets of piston cylinders 19 are fixedly connected to the outer wall of partition 2 18. The two sets of piston cylinders 19 are symmetrically installed on both sides of partition 2 18 and welded to it. The piston cylinders 19 have a cylindrical structure, providing good sealing and pressure resistance. A piston head 22 is slidably connected inside the piston cylinder 19. The outer wall of the piston head 22 is tightly fitted to the inner wall of the piston cylinder 19 and is made of a sealing material to ensure a tight seal between the piston head 22 and the piston cylinder 19, preventing gas leakage. One end of a piston rod 21 is fixedly connected to the outer wall of the piston head 22. The piston rod 21 is coaxially arranged with the piston head 22 and fixed as a single unit by welding. The other end of the piston rod 21 passes through the end of the piston cylinder 19 and extends to the outside of the piston cylinder 19. The outer wall of the piston rod 21 is sealed to the end of the piston cylinder 19, ensuring that gas does not leak from the connection between the piston rod 21 and the piston cylinder 19. A connecting plate 20 is fixedly connected to the other end of the piston rod 21. The connecting plate 20 has a rectangular structure and is fixedly connected to the end of the piston rod 21 by bolts. The outer wall of the connecting plate 20 is fixedly connected to the lower surface of the sliding frame 6 by bolts, so that the sliding frame 6 and the piston rod 21 are connected synchronously. The sliding of the sliding frame 6 can drive the piston rod 21 to move together. A cleaning mechanism 25 is provided on the outer wall of the piston cylinder 19. The cleaning mechanism 25 is connected to the inside of the piston cylinder 19 and is used to discharge the compressed gas generated in the piston cylinder 19 to achieve the cleaning operation of the workpiece. One end of the piston cylinder 19 near the piston rod 21 is a closed structure, and the other end is an open structure. An air inlet is provided at the open end to replenish the gas inside the piston cylinder 19. In actual operation, the sliding frame 6 slides back and forth under the drive of the drive mechanism 5. The sliding frame 6 drives the piston rod 21 to move back and forth synchronously through the connecting plate 20. The piston rod 21 drives the piston head 22 to slide back and forth inside the piston cylinder 19. When the piston head 22 moves towards the closed end of the piston cylinder 19, the gas inside the piston cylinder 19 is compressed, forming compressed gas. When the piston head 22 moves towards the open end of the piston cylinder 19, a negative pressure is created inside the piston cylinder 19, and external gas enters the piston cylinder 19 through the air inlet, completing the gas replenishment. The compressed gas generated inside the piston cylinder 19 is ejected through the cleaning mechanism 25 to clean the workpiece.
[0038] The cleaning mechanism 25 includes a connecting pipe 2501, the outer wall of which is fixedly connected to the outer wall of the piston cylinder 19 and the outer wall of the workbench 1. A nozzle 2502 is fixedly connected to the port of the connecting pipe 2501. The nozzle 2502 is located on the upper side of the clamping mechanism 10. One-way valves 23 are provided on the outer walls of both the connecting pipe 2501 and the piston cylinder 19.
[0039] Specifically, the cleaning mechanism 25 includes a connecting pipe 2501. The outer wall of the connecting pipe 2501 is fixedly connected to the outer wall of the piston cylinder 19 by pipe clamps. One end of the connecting pipe 2501 communicates with the interior of the piston cylinder 19, and a sealing joint is provided at the connection point to ensure that the gas does not leak. The outer wall of the connecting pipe 2501 is fixedly connected to the outer wall of the worktable 1 by pipe clamps, and extends along the outer wall of the worktable 1 to the top of the clamping mechanism 10. Its arrangement path avoids components such as the drilling mechanism 2 and the rotary motor 9 to avoid affecting the normal operation of other components. A nozzle 2502 is fixedly connected to the end of the connecting pipe 2501. The nozzle 2502 is a high-pressure nozzle that can spray compressed gas in the form of a high-speed airflow. The nozzle 2502 is located on the upper side of the clamping mechanism 10, and its spray direction is aimed at the workpiece between the active clamping plate 11 and the passive clamping plate 12 to ensure that the airflow can directly act on the surface of the workpiece. Both the connecting pipe 2501 and the outer wall of the piston cylinder 19 are equipped with one-way valves 23. The one-way valve 23 on the piston cylinder 19 is installed at the air inlet at its open end to control the one-way entry of gas into the piston cylinder 19 and prevent the compressed gas inside the piston cylinder 19 from leaking out of the air inlet. The one-way valve 23 on the connecting pipe 2501 is installed at the end of the connecting pipe 2501 near the piston cylinder 19 and is used to control the one-way flow of compressed gas from the piston cylinder 19 to the nozzle 2502 to prevent external dust and debris from entering the piston cylinder 19 through the connecting pipe 2501 and affecting the normal operation of the piston cylinder 19. In actual cleaning operations, the compressed gas generated inside the piston cylinder 19 is transported to the nozzle 2502 through the connecting pipe 2501 and sprayed out by the nozzle 2502 to form a high-speed airflow. The airflow blows directly onto the surface of the active clamping plate 11, the passive clamping plate 12, and the workpiece clamped between them, blowing off the debris and residual coolant attached to the surface, thus cleaning the workpiece. Simultaneously, the rotary motor 9 drives the workpiece to rotate, erecting it. At this time, the high-speed airflow can blow into the drilled hole of the workpiece, thoroughly blowing out the residual debris inside the drilled hole, preventing debris residue from affecting the machining accuracy and subsequent assembly quality. When the gas in the piston cylinder 19 is compressed to a certain pressure, the one-way valve 23 automatically opens, and the compressed gas is smoothly delivered to the nozzle 2502 through the connecting pipe 2501. When a negative pressure is formed inside the piston cylinder 19, the one-way valve 23 on the connecting pipe 2501 closes, and the one-way valve 23 on the piston cylinder 19 opens, allowing outside gas to enter the piston cylinder 19, preparing for the generation of the next compressed gas.
[0040] Blades 24 are fixedly connected to the outer walls of both the active clamping plate 11 and the passive clamping plate 12.
[0041] Specifically, blades 24 are fixedly connected to the outer walls of both the active clamping plate 11 and the passive clamping plate 12. The blades 24 possess good hardness and wear resistance, effectively cutting off tangled long chips. The blades 24 are evenly distributed on the outer walls of the active clamping plate 11 and the passive clamping plate 12, spaced apart along the circumference of the clamps. The cutting edges of the blades 24 face outwards, ensuring smooth chip cutting while preventing excessive sharpness that could damage the workpiece. In actual machining, drilling operations may generate long, curled metal chips. These chips easily become entangled on the active clamping plate 11, the passive clamping plate 12, or the workpiece. If not handled promptly, they can affect the clamping stability of the workpiece and drilling accuracy, and may even damage the drilling tools. When the rotary motor 9 drives the active clamping plate 11 and the passive clamping plate 12 to rotate, the blade 24 fixed on its outer wall also rotates synchronously. The rotating blade 24 can cut off the long debris wrapped around the clamping plate and the workpiece. The cut debris will fall onto the guide plate 8 below and then be guided to the filter plate 3 for filtration, avoiding processing failures caused by long debris entanglement and ensuring smooth drilling. At the same time, the setting of the blade 24 does not affect the clamping effect of the active clamping plate 11 and the passive clamping plate 12 on the workpiece. The height of the blade 24 is lower than the clamping surface of the clamping plate, ensuring that the blade 24 will not contact the workpiece during clamping and avoiding scratches on the surface of the workpiece.
