Technical Field

[0001] This invention relates to the field of machine tool technology, specifically to a multifunctional composite machine tool that integrates turning, milling, grinding, and drilling functions. Background Technology

[0002] In the field of mechanical manufacturing, the machining of cylindrical workpieces such as steel pipes and shafts typically involves multiple core processes, including turning, grinding, and drilling. These processes are crucial for ensuring the dimensional accuracy, surface quality, and functional reliability of the workpieces. As modern industry continuously demands higher processing efficiency, precision, and integration levels for parts, it drives the development of composite machine tools.

[0003] When using traditional equipment, if the cutting tool is used to process steel for a long time, the material of the cutting tool may be damaged due to high temperature, which will affect the processing accuracy. Furthermore, the residue left on the steel surface or the cutting tool during the processing will further affect the processing accuracy and thus affect the processing stability. Summary of the Invention

[0014] Preferably, the other two sets of through holes penetrate the grinding plate, the grinding plate is arc-shaped, and the arc angle of the grinding plate matches the outer diameter of the steel pipe.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention completes the cutting process simultaneously with the grinding process, eliminating the need for two separate steps and shortening the overall processing time of the steel pipe. The grinding plate assists the cutting tool in real time, promptly treating the surface of the steel pipe after cutting, reducing the need for subsequent secondary processing and making the surface smoother. At the same time, the air curtains on both sides can effectively intercept the flying cutting residue, preventing residue from polluting the environment, damaging equipment, or posing safety hazards to operators. The air curtains also gather the residue together, facilitating subsequent cleaning.

[0019] 2. In this invention, when a lathe tool is turning a steel pipe, the airflow cools the tool, and the downward force of the airflow helps the residue to detach from the tool surface, preventing residue from remaining on the tool surface and causing cutting deviation. Thus, by cooling the tool through the airflow, the wear of the tool material caused by high temperature during turning is reduced, extending its service life. At the same time, the downward force of the airflow helps the residue to detach from the tool, preventing residue from causing cutting deviation. This ensures stable machining while preventing residue from remaining on the tool surface and affecting cutting accuracy.

[0020] 3. This invention utilizes the synergistic effect of airflow and cutting fluid on the grinding plate to quickly remove the heat generated during grinding, preventing damage to the grinding plate due to high temperature and affecting the grinding effect. At the same time, by reducing the angle, the impact force of the airflow is enhanced, which can promote the rapid diffusion of the cutting fluid, thereby promptly removing grinding residue and preventing residue from being trapped between the grinding plate and the steel pipe surface, effectively preventing grinding scratches on the steel pipe surface.

[0021] 4. During cutting, the grinding plate intermittently rises to contact the steel pipe, instantly polishing the machined area to remove residue and pre-treating the unmachined area. This ensures seamless process continuity and effectively improves machining efficiency. The remaining gas, through the jet vent, forms a stable air curtain, guaranteeing machining efficiency while simultaneously blocking cutting fluid and residue splashes, ensuring stable operation of the device. After machining, the air curtain is reflected onto the steel pipe surface by the guide plate, which, in conjunction with the continuous rotation of the guide plate, forms a dynamic scanning airflow. This quickly dries the cutting fluid and blows off residual machining residue from the steel pipe surface, preventing surface scratches caused by residue adhesion during subsequent transportation.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0033] Reference Figures 1-9 The present invention provides a multi-functional composite machine tool integrating turning, milling, grinding and drilling functions, including a first clamping seat 2 installed on the upper end of the base 1, a second clamping seat 3 sliding on the upper surface of the base 1, two sets of air jet grooves 7 provided on the upper ends of the first clamping seat 2 and the second clamping seat 3, one end of the two sets of air jet grooves 7 being connected to a fan, an infusion pipe 21 installed on one side of each of the two sets of air jet grooves 7, one end of the infusion pipe 21 being connected to a liquid storage device, and multiple sets of nozzles 22 installed on the outside of the infusion pipe 21;

[0034] A first guide seat 9 is installed on one side of the base 1. A cutting tool 13 and a connecting frame 14 slide on the upper end of the first guide seat 9. A guide groove 16 is installed on the upper end of the connecting frame 14. A grinding plate 15 is installed on one side of the connecting frame 14. The interior of the connecting frame 14 is hollow, and three sets of through holes 17 are opened inside the connecting frame 14.

[0035] A second guide seat 18 is installed on the other side of the base 1. Two sets of motors C20 slide on the upper end of the second guide seat 18. The output ends of the two sets of motors C20 are respectively connected to a drill bit and a milling cutter.

[0036] In an optional embodiment, a first motor 4 is installed at one end of the base 1, and a first threaded rod 5 is connected to the output end of the first motor 4. A sliding groove is opened at the lower end of the second clamping seat 3. The first threaded rod 5 extends through the base 1 into the sliding groove, and the first threaded rod 5 is threadedly connected to the lower end of the second clamping seat 3. The first clamping seat 2 and the second clamping seat 3 are located on the same plane.

[0037] Before using the device, the operator hoists the steel pipe to be processed between the first clamping seat 2 and the second clamping seat 3. At this time, the first motor 4 is started. After the first motor 4 starts, it drives the first threaded rod 5 to rotate. When the first threaded rod 5 rotates, it drives the second clamping seat 3 to slide, thereby clamping the steel pipe between the first clamping seat 2 and the second clamping seat 3. After the first clamping seat 2 and the second clamping seat 3 clamp the steel pipe, because the first clamping seat 2 is equipped with a drive rotor inside and the output end of the drive rotor is connected to the first clamping seat 2, the first clamping seat 2 will drive the steel pipe to rotate.

[0038] In an optional embodiment, brackets 6 are installed at both ends of the two sets of air jet channels 7. The bracket 6 near the first clamping seat 2 is fixedly connected to the first clamping seat 2, and the bracket 6 near the second clamping seat 3 is slidably connected to the second clamping seat 3. As described above, when the second clamping seat 3 slides, because the bracket 6 is slidably connected to the second clamping seat 3, the bracket 6 will not be displaced when the second clamping seat 3 slides.

[0039] In an optional embodiment, each of the two sets of jet channels 7 is fixedly connected to a connecting pipe A8 at one end, and the other end of each of the two sets of connecting pipes A8 is connected to the output end of the fan. When using the device, the fan will turn on simultaneously. After the fan is turned on, the fan will deliver airflow through the two sets of connecting pipes A8 to the two sets of jet channels 7 for ejection. When the airflow is ejected through the two sets of jet channels 7, since the two sets of jet channels 7 are located on both sides of the first clamping seat 2, the gas ejected through the jet channels 7 will form an air curtain on both sides of the second clamping seat 3, thereby promoting the flow of air around the steel pipe.

[0040] In an optional embodiment, one end of each of the two sets of infusion tubes 21 is fixedly connected to a connecting tube B23, and the other end of the connecting tube B23 is connected to a liquid storage device. Multiple sets of nozzles 22 are installed on the outside of the infusion tubes 21. When using the device, cutting fluid is simultaneously delivered into the infusion tubes 21 through the liquid storage device and the two sets of connecting tubes B23. After the cutting fluid enters the infusion tubes 21, it is sprayed outward through the multiple sets of nozzles 22. Since the multiple sets of nozzles 22 are all biased towards the center of the steel pipe, the cutting fluid is sprayed onto the upper end of the steel pipe. At this time, with the rotation of the steel pipe, the cutting fluid is evenly distributed on the surface of the steel pipe.

[0041] In an optional embodiment, a second motor 10 is installed at one end of both the first guide seat 9 and the second guide seat 18. The output ends of both sets of second motors 10 are connected to second threaded rods 11. One set of second threaded rods 11 is threadedly connected to a first cylinder 12 on its outer side. The first cylinder 12 is located at the upper end of the first guide seat 9. The output end of the first cylinder 12 is fixedly connected to a cutting tool 13 and a connecting frame 14.

[0042] When turning the steel pipe, the second motor 10 drives the second threaded rod 11 to rotate, thereby controlling the horizontal movement of the first cylinder 12. During the movement, the first cylinder 12 pushes the cutting tool 13 to extend, so that the cutting tool 13 contacts the steel pipe. After the cutting tool 13 contacts the steel pipe, the cutting tool 13 removes the excess part on the surface of the steel pipe by means of the rotation of the steel pipe. When the first cylinder 12 pushes the cutting tool 13 to contact the surface of the steel pipe, it also pushes the connecting frame 14 to move, so that the grinding plate 15 contacts the surface of the steel pipe. After the grinding plate 15 contacts the surface of the steel pipe, the surface of the steel pipe is ground by means of the rotation of the steel pipe. Thus, when the cutting tool 13 is turning the surface of the steel pipe, the grinding plate 15 will grind the surface of the steel pipe simultaneously, thereby assisting the cutting tool 13 in turning.

[0043] Simultaneously, as described above, the gas ejected from the two sets of jet channels 7 forms an air curtain on both sides of the steel pipe. This air curtain intercepts the debris splashed by the cutting tool 13 during the turning process, further preventing debris from splashing. Thus, the cutting by the cutting tool 13 and the grinding by the grinding plate 15 are completed simultaneously, eliminating the need for two separate processes and shortening the overall processing time of the steel pipe. Furthermore, the grinding plate 15 assists the cutting tool 13 in real time, promptly treating the surface of the steel pipe after cutting, reducing the need for subsequent secondary processing, and making the surface smoother. At the same time, the air curtains on both sides can effectively intercept the splashed cutting debris, preventing the debris from polluting the environment, damaging equipment, or posing safety hazards to operators. The air curtains also gather the debris together, facilitating subsequent cleaning.

[0044] In an optional embodiment, one set of through holes 17 penetrates the connecting frame 14 and is located on the same vertical plane as the cutting tool 13. As described above, when the first cylinder 12 pushes the cutting tool 13 and the connecting frame 14 to move, it will simultaneously drive the guide groove 16 to move. After the guide groove 16 moves, it will be located at the lower end of the jet groove 7. Since the interior of the connecting frame 14 is hollow, when the guide groove 16 is located at the lower end of the jet groove 7, the gas ejected from the jet groove 7 will enter the interior of the connecting frame 14 through the guide groove 16. After the gas enters the interior of the connecting frame 14, some of the gas will be blown toward the cutting tool 13 through one of the through holes 17, thereby causing part of the wind force of the air curtain to act on the cutting tool 13. 3. Surface cooling: When the cutting tool 13 is turning the steel pipe, the airflow cools the cutting tool 13, and the downward force of the airflow helps the residue to detach from the surface of the cutting tool 13, preventing residue from remaining on the surface of the cutting tool 13 and causing cutting deviation. Thus, by cooling the cutting tool 13 through the airflow, the wear of the cutting tool 13 material caused by high temperature during turning is reduced, extending its service life. At the same time, the downward force of the airflow helps the residue to detach from the cutting tool 13, preventing residue from causing cutting deviation. This ensures stable machining while preventing residue from remaining on the surface of the cutting tool 13 and affecting cutting accuracy.

[0045] In an optional embodiment, two additional sets of through holes 17 penetrate the grinding plate 15, which is arc-shaped, and the arc angle of the grinding plate 15 matches the outer diameter of the steel pipe. As described above, after the airflow of the air curtain enters the connecting frame 14 through the guide groove 16, the remaining gas acts on the grinding plate 15 and the surface of the steel pipe through the two sets of through holes 17. This, in turn, cools the grinding plate 15 simultaneously through the interaction between the cutting fluid and the airflow. Furthermore, as the airflow travels between the grinding plate 15 and the surface of the steel pipe, the small angle between them increases the impact force of the airflow. At this time, the airflow blows the cutting fluid outwards, thus quickly removing the grinding residue along with the cutting fluid. The surface of the grinding plate 15 is designed to prevent scratches on the steel pipe surface caused by excessive residue during grinding. By using airflow and cutting fluid in synergy, the heat generated during grinding is quickly carried away, preventing damage to the grinding plate 15 due to high temperature and affecting the grinding effect. At the same time, the reduced angle enhances the impact force of the airflow, which can promote the rapid diffusion of cutting fluid, thereby timely removing grinding residue and preventing residue from being trapped between the grinding plate 15 and the steel pipe surface, effectively preventing grinding scratches on the steel pipe surface.

[0046] In an optional embodiment, two sets of second cylinders 19 are threadedly connected to the outer side of another set of second threaded rods 11, and the output ends of both sets of second cylinders 19 are connected to motors C20. When using the device, the second threaded rods 11 can also be driven to rotate by another set of second motors 10, depending on the actual situation. When the second threaded rods 11 rotate, they will drive the two sets of second cylinders 19 to slide synchronously. At this time, the two sets of second cylinders 19 can push the two sets of motors C20 outwards, and then the motors C20 can drive a drill bit or milling cutter to further process the steel pipe, thereby integrating multiple functions, reducing the number of times the steel pipe needs to be transferred during processing, and improving processing efficiency.

[0047] In an optional embodiment, a connecting pipe C30 is connected to one side of the connecting pipe A8. A valve is installed inside the connecting pipe C30. A half gear 24 is fixedly connected to one end of the second threaded rod 11. A full gear A25 and a full gear B35 are respectively meshed on both sides of the half gear 24. A one-way clutch A26 is connected to one end of the full gear A25. A valve stem 27 is connected to one end of the one-way clutch A26. The other end of the valve stem 27 extends through the connecting pipe C30 and into the connecting pipe C30 to connect with the valve. Multiple sets of fixing buckles A28 are sleeved on the outside of the valve stem 27. The fixing buckles A28 are connected to the first guide seat 9. One set of... One end of the fixed buckle A28 is connected to a torsion spring 29, and the other end of the torsion spring 29 is connected to a one-way clutch A26. The other end of the connecting pipe C30 is connected to a guide pipe 31. A pressure relief valve 34 is installed on the outside of the guide pipe 31, and a push rod 32 is slidably connected inside the guide pipe 31. One end of the push rod 32 is fixedly connected to a grinding plate 33. One end of the full gear B35 is connected to a one-way clutch B36, and one end of the one-way clutch B36 is connected to a rotating shaft 37. Two sets of fixed buckles B38 are sleeved on the outside of the rotating shaft 37. Both sets of fixed buckles B38 are connected to the first guide seat 9. A guide plate 39 is connected to the outside of the rotating shaft 37.

[0048] As described above, when the second threaded rod 11 rotates to drive the first cylinder 12 to move, the second threaded rod 11 will synchronously drive the half gear 24 to rotate. When the half gear 24 rotates, it will synchronously drive the full gear A25 and full gear B35 to rotate. When the full gear A25 rotates, it will synchronously drive the one-way clutch A26 to rotate. When the full gear B35 rotates, it will not drive the one-way clutch B36 to rotate. When the one-way clutch A26 rotates, it will synchronously drive the valve stem 27 to rotate. When the valve stem 27 rotates, it will open the valve inside the connecting pipe C30. The outer teeth of gear 24 are fewer, resulting in a smaller rotation degree of the full gear A25 when the half gear 24 drives the full gear A25 to rotate. Furthermore, the rotation of the one-way clutch A26 synchronously drives the torsion spring 29 to rotate. As the half gear 24 continues to rotate, it disengages from the full gear A25. After disengagement, the one-way clutch A26 rotates and resets under the force of the torsion spring 29. Simultaneously, the one-way clutch A26 resets, synchronously driving the full gear A25 to rotate and reset. Thus, as the half gear 24 continues to rotate, it causes... The valve inside connecting pipe C30 opens intermittently. After the valve opens, some of the gas entering the jet tank 7 through connecting pipe A8 enters connecting pipe C30. Once inside connecting pipe C30, the gas is transported to guide pipe 31. Because the intake volume of connecting pipe C30 is greater than the exhaust volume of pressure relief valve 34, pressure is created inside guide pipe 31. This increased pressure pushes push rod 32 outwards. Simultaneously, push rod 32 will push grinding plate 33 upward. When grinding plate 33 moves upward, it will contact the steel pipe. When grinding plate 33 contacts the steel pipe, grinding plate 33 will polish the machined part of the outer wall of the steel pipe and remove the cutting residue attached to the surface. When grinding plate 33 contacts the unmachined part of the steel pipe, grinding plate 33 will pre-treat the unmachined part. At the same time, after the gas enters the interior of connecting pipe C30, the remaining gas will still form an air curtain when it is ejected through jet groove 7. Thus, the air curtain will not disappear due to some gas entering the interior of connecting pipe C30.

[0049] After the turning is completed, as the second threaded rod 11 rotates in the reverse direction to drive the first guide seat 9 to reset, the full gear A25 will not drive the one-way clutch A26 to rotate. Instead, the full gear B35 will drive the one-way clutch B36 to rotate synchronously. When the one-way clutch B36 rotates, it will synchronously drive the rotating shaft 37 to rotate. When the rotating shaft 37 rotates, it will synchronously drive the guide plate 39 to flip, thereby changing the guide plate 39 from a vertical state to a parallel state. After the guide plate is in the forward position, due to the damping force between the rotating shaft 37 and the fixed buckle B38, the weight of the guide plate 39 is less than the damping force after the rotating shaft 37 drives it to rotate. Therefore, the rotating shaft 37 will not automatically descend and reset due to the weight of the guide plate 39. At the same time, after the guide plate 39 flips over, it will contact the downward air curtain of the jet groove 7. After the guide plate 39 contacts the air curtain, the air curtain will exert an impact force on the guide plate 39, causing the guide plate 39 to gradually flip downward. When the guide plate 39 descends and resets, it will simultaneously... The rotating shaft 37 is reset, and as the half gear 24 continues to rotate, the guide plate 39 will continuously flip and reset. When the air curtain contacts the guide plate 39, the air curtain will be reflected onto the surface of the machined steel pipe through the guide plate 39. At this time, in conjunction with the continuous flipping and resetting of the guide plate 39, the airflow of the air curtain will continuously act on the surface of the steel pipe, thereby quickly drying the cutting fluid and blowing off the residual machining residue. Thus, during cutting, the grinding plate 33 intermittently rises and contacts the steel pipe, instantly polishing the machined area of ​​the steel pipe to remove residue, while simultaneously polishing the unmachined area. Pre-treatment in the field ensures seamless process transitions and effectively improves processing efficiency. The remaining gas can still form a stable air curtain through the jet vent 7, ensuring processing efficiency while simultaneously blocking the splashing of cutting fluid and residue, ensuring stable operation of the device. After turning, the air curtain is reflected to the surface of the steel pipe by the guide plate 39. With the continuous rotation of the guide plate, a dynamic scanning airflow is formed, which not only quickly dries the cutting fluid but also blows off the residual processing residue on the surface of the steel pipe, preventing surface scratches caused by residue adhesion during subsequent transportation of the steel pipe.

[0050] The working principle of this invention is as follows:

[0051] Before using the device, the workers hoist the steel pipe to be processed between the first clamping seat 2 and the second clamping seat 3. At this time, the first motor 4 is started. After the first motor 4 is started, it will drive the first threaded rod 5 to rotate. When the first threaded rod 5 rotates, it will drive the second clamping seat 3 to slide, thereby clamping the steel pipe between the first clamping seat 2 and the second clamping seat 3. After the first clamping seat 2 and the second clamping seat 3 clamp the steel pipe, the first clamping seat 2 will drive the steel pipe to rotate.

[0052] When using the device, the fan will be turned on simultaneously. After the fan is turned on, the fan will deliver air through two sets of connecting pipes A8 to two sets of jet ducts 7 and spray it out. When the air is sprayed out through the two sets of jet ducts 7, since the two sets of jet ducts 7 are located on both sides of the first clamping seat 2, the gas sprayed out through the jet ducts 7 will form an air curtain on both sides of the second clamping seat 3, thereby promoting the air flow around the steel pipe. When using the device, the cutting fluid will be delivered to the inside of the liquid delivery pipe 21 through the liquid storage device and two sets of connecting pipes B23. After the cutting fluid enters the inside of the liquid delivery pipe 21, it will be sprayed out through multiple sets of nozzles 22. Since the multiple sets of nozzles 22 are all biased towards the center of the steel pipe, the cutting fluid will be sprayed on the upper end of the steel pipe. At this time, with the rotation of the steel pipe, the cutting fluid will be evenly distributed on the surface of the steel pipe.

[0053] When turning the steel pipe, the second motor 10 drives the second threaded rod 11 to rotate, thereby controlling the horizontal movement of the first cylinder 12. During the movement, the first cylinder 12 pushes the cutting tool 13 to extend, so that the cutting tool 13 contacts the steel pipe. After the cutting tool 13 contacts the steel pipe, the cutting tool 13 removes the excess part on the surface of the steel pipe by rotating the steel pipe. When the first cylinder 12 pushes the cutting tool 13 to contact the surface of the steel pipe, it also pushes the connecting frame 14 to move, so that the grinding plate 15 contacts the surface of the steel pipe. After the grinding plate 15 contacts the surface of the steel pipe, the surface of the steel pipe is ground by rotating the steel pipe. So when the cutting tool 13 turns the surface of the steel pipe, the grinding plate 15 grinds the surface of the steel pipe simultaneously, thereby assisting the cutting tool 13 in turning. At the same time, the gas ejected from the two sets of air jets 7 forms an air curtain on both sides of the steel pipe, and the air curtain intercepts the residue splashed by the cutting tool 13 during the turning process.

[0054] When the first cylinder 12 pushes the cutting tool 13 and the connecting frame 14 to move, it will simultaneously drive the guide groove 16 to move. After the guide groove 16 moves, the guide groove 16 will be located at the lower end of the jet groove 7. Since the interior of the connecting frame 14 is hollow, when the guide groove 16 is located at the lower end of the jet groove 7, the gas ejected from the jet groove 7 will enter the interior of the connecting frame 14 through the guide groove 16. After the gas enters the interior of the connecting frame 14, some of the gas will be blown toward the cutting tool 13 through one of the through holes 17, thereby causing part of the wind force of the air curtain to act on the surface of the cutting tool 13. Thus, when the cutting tool 13 is turning the steel pipe, the airflow will cool the cutting tool 13, and the vertical downward force of the airflow will help the residue to leave the surface of the cutting tool 13.

[0055] After the airflow of the air curtain enters the interior of the connecting frame 14 through the guide groove 16, the remaining gas will act on the surface of the grinding plate 15 and the steel pipe through the two sets of through holes 17. Then, the grinding plate 15 will be cooled down synchronously through the interaction between the cutting fluid and the airflow. When the airflow shuttles between the surface of the grinding plate 15 and the steel pipe, the angle between the surface of the grinding plate 15 and the steel pipe is small, which will increase the impact force of the airflow. At this time, the airflow will blow the cutting fluid to spread in all directions, and then the grinding residue will be quickly removed from the surface of the grinding plate 15 along with the cutting fluid.

[0056] When using the device, the second threaded rod 11 can be driven to rotate by another set of second motors 10 according to the actual situation. When the second threaded rod 11 rotates, it will drive the two sets of second cylinders 19 to slide synchronously. At this time, the two sets of second cylinders 19 can push the two sets of motors C20 out, and then the motors C20 can drive the drill bit or milling cutter to further process the steel pipe.

[0057] When the second threaded rod 11 rotates to drive the first cylinder 12 to move, the second threaded rod 11 will synchronously drive the half gear 24 to rotate. When the half gear 24 rotates, it will synchronously drive the full gear A25 and full gear B35 to rotate. When the full gear A25 rotates, it will synchronously drive the one-way clutch A26 to rotate. When the full gear B35 rotates, it will not drive the one-way clutch B36 to rotate. When the one-way clutch A26 rotates, it will synchronously drive the valve stem 27 to rotate. When the valve stem 27 rotates, it will open. The valve inside connecting pipe C30 has fewer teeth on the outer side of the half gear 24, resulting in a smaller rotation degree of the full gear A25 when the half gear 24 drives the full gear A25 to rotate. Furthermore, when the one-way clutch A26 rotates, it synchronously drives the torsion spring 29 to rotate. As the half gear 24 continues to rotate, it disengages from the full gear A25. After disengagement, the one-way clutch A26 is reset by the force of the torsion spring 29. Simultaneously with the reset of the one-way clutch A26... The synchronous rotation of the full gear A25 resets the gear, and the continuous rotation of the half gear 24 causes the valve inside the connecting pipe C30 to open intermittently. After the valve opens, some of the gas entering the jet chamber 7 through the connecting pipe A8 enters the connecting pipe C30. Once inside the connecting pipe C30, it delivers the gas to the guide pipe 31. Because the intake volume of the connecting pipe C30 is greater than the exhaust volume of the pressure relief valve 34, the gas then... Gas pressure is generated inside the guide tube 31. When the gas pressure inside the guide tube 31 increases, the gas pressure will push the push rod 32 outward. As the push rod 32 pushes outward, it will simultaneously push the grinding plate 33 upward. When the grinding plate 33 moves upward, it will contact the steel pipe. When the grinding plate 33 contacts the steel pipe, it will polish and grind the machined part of the outer wall of the steel pipe and remove the cutting residue attached to the surface. When the grinding plate 33 contacts the unmachined part of the steel pipe, it will pre-treat the unmachined part.

[0058] After the turning is completed, as the second threaded rod 11 rotates in the reverse direction to drive the first guide seat 9 to reset, the full gear A25 will not drive the one-way clutch A26 to rotate. Instead, the full gear B35 will drive the one-way clutch B36 to rotate synchronously. When the one-way clutch B36 rotates, it will synchronously drive the rotating shaft 37 to rotate. When the rotating shaft 37 rotates, it will synchronously drive the guide plate 39 to flip, thereby changing the guide plate 39 from a vertical state to a parallel state. After the guide plate 39 changes to a parallel state, due to the damping force between the rotating shaft 37 and the fixed buckle B38, after the rotating shaft 37 drives the guide plate 39 to rotate, the guide plate 39 will then... The weight of 9 is less than the damping force, so the rotating shaft 37 will not automatically descend and reset due to the weight of the guide plate 39. At the same time, after the guide plate 39 flips, it will contact the downward air curtain of the jet groove 7. After the guide plate 39 contacts the air curtain, the air curtain will exert an impact force on the guide plate 39, causing the guide plate 39 to gradually flip downward. When the guide plate 39 descends and resets, it will synchronously drive the rotating shaft 37 to reset. As the half gear 24 continues to rotate, the guide plate 39 will continuously flip and reset. When the air curtain contacts the guide plate 39, the air curtain will be reflected through the guide plate 39 to the surface of the processed steel pipe. At this time, in conjunction with the continuous flipping and resetting of the guide plate 39, the airflow of the air curtain will continuously act on the surface of the steel pipe.
