Description

Technical Field

[0001] This invention relates to the field of pipe processing, and in particular to a highly adaptable pipe cutting machine. Background Technology

[0002] In the production and processing of pipes, laser cutting machines are generally required for cutting. A laser cutting machine includes a clamp and a laser cutting head. The laser cutting head has movement adjustment settings, and the clamp is used to clamp the pipes fed to the laser cutting machine, so that the pipes remain stable at the processing position; while the laser cutting head performs cutting operations on the outside of the pipes during the movement.

[0003] After the pipe cutting work is completed, burrs and flashes will inevitably appear at the holes on the inner wall of the pipe. Compared with the metal fragments that splash into the inside of the pipe, the burrs often exist on the inner wall of the pipe in the form of adhesion after they are formed, and it is difficult to effectively remove the burrs by conventional dumping methods.

[0004] Refer to the patent document with announcement number “”.

[0005] In the aforementioned prior art, the deburring operation is mainly completed by a scraper. However, in actual operation, it has been found that the scraping method alone is not effective in removing burrs. When the burrs are scraped, they are very likely to be pressed into the cutting surface, resulting in incomplete removal.

[0006] Existing technology (patent document with publication number "CN119237970B") discloses a pipe laser drilling device, including a frame and a feeding mechanism, a positioning mechanism, and a laser cutting mechanism mounted on top of it. A support plate is mounted on the frame, and a support rod capable of inserting into the inner cavity of a pipe is located in the center of the support plate. A frame is laterally slidably connected to one end of the support rod near the laser cutting mechanism via a spring. Rubber rings that abut against the inner wall of the pipe are located at both ends of the outer surface of the frame. Two scrapers are vertically slidably connected to a vertical hole on the support rod via a tension spring. A hydraulic cavity is formed inside the support rod, and this hydraulic cavity is simultaneously connected to the vertical hole and the groove where the frame is located. A locking element is provided on the support rod to lock the scrapers inside the vertical hole. This pipe laser drilling device can achieve automatic feeding and quantitative cutting and drilling operations on pipes through the feeding mechanism, positioning mechanism, and laser cutting mechanism.

[0007] Based on the above search and combined with existing technology, it was found that existing pipeline cutting machines similar to those mentioned above mainly use scrapers for deburring. However, in actual operation, it was found that using only scrapers to remove burrs is not very effective. When burrs are scraped, they are very likely to be pressed into the cutting surface, resulting in incomplete removal. Summary of the Invention

[0008] The core of this invention lies in solving the problem of poor burr removal efficiency in existing technologies through the coordinated use of a fixed ring, a split ring, a grinding roller, a drive mechanism, and a transmission mechanism. It also further improves deburring efficiency and enhances the reliability of the equipment.

[0009] To solve the above problems, the present invention adopts the following technical solution.

[0010] A highly adaptable pipe cutting machine includes a frame and a feeding mechanism, a positioning mechanism and a laser cutting mechanism installed on top of it. The frame is equipped with a support plate, and a support rod that can be inserted into the inner cavity of the pipe is provided in the middle of the support plate. L-shaped cantilever arms for auxiliary support of the pipe are installed on both the front and rear sides of the frame.

[0011] The load-bearing rod includes a main rod body with the same length and width as the inner side of the pipe and an installation rod head integrally formed at the front end of the main rod body, with a gap formed between the periphery of the installation rod head and the periphery of the pipe.

[0012] An interception ring assembly is installed on the mounting pole head. The interception ring assembly includes a fixed ring and a split ring. The fixed ring is fixedly sleeved on the end of the mounting pole head near the main pole body. The split ring has a through-ring gap in the middle that divides the split ring into inner and outer rings. The inner ring of the split ring is fixedly sleeved on the end of the mounting pole head, and the outer ring of the split ring is movably sleeved on the outside of the inner ring of the fixed ring through a movable support.

[0013] The fixed ring and the split ring are located on both sides of the part of the pipe to be processed, and a grinding roller is movably installed between the fixed ring and the split ring. The circumference of the grinding roller is in contact with the inner wall of the pipe.

[0014] The bearing plate, the main rod body, and the mounting rod head are all equipped with a transmission mechanism and a drive mechanism that drive the grinding roller to move circumferentially along the side of the mounting rod head.

[0015] By incorporating a fixed ring, a split ring, a grinding roller, a drive mechanism, and a transmission mechanism, the fixed ring and split ring are positioned on either side of the pipe's processing location during drilling and cutting. This restricts the debris generated during drilling or cutting, preventing it from scattering. After processing, the drive mechanism and transmission mechanism drive the grinding roller to move circumferentially along the mounting rod head, allowing it to rotate circumferentially inside the pipe and grind away burrs. The grinding during roller rotation is more thorough, removing burrs circumferentially. Compared to lateral scraping, circumferential grinding is more effective at removing burrs and also provides internal support for the pipe, maintaining its stability during processing.

[0016] Furthermore, the transmission mechanism includes:

[0017] The drive short shaft is fixed to the output end of the drive mechanism and located at the front end of the mounting rod head;

[0018] The telescopic rod has one end fixed to the periphery of the drive shaft, and the movable end of the telescopic rod extends outward toward the mounting head.

[0019] A rotating rod is rotatably inserted into the movable end of a telescopic rod. The rotating rod rotates through the annular gap and is fixed to the grinding roller.

[0020] The limiting rotating sleeve is a movable support component. The limiting rotating sleeve is rotatably mounted on the rotating rod and is movably embedded in the through annular gap.

[0021] Furthermore, the limiting rotating sleeve includes:

[0022] Small diameter ring, the small diameter ring is rotatably sleeved on the rotating rod, the outer diameter of the small diameter ring is the same as the width of the through ring gap;

[0023] The large diameter ring is integrally formed with the small diameter ring, and the diameter of the large diameter ring is larger than the diameter of the small diameter ring.

[0024] Among them, a limiting ring gap is also provided on the split ring. The limiting ring gap is connected to the through ring gap, and the width of the limiting ring gap is greater than the width of the through ring gap. The limiting ring gap is located in the middle of the through ring gap. The large diameter ring is movably embedded in the limiting ring gap, and the outer diameter of the large diameter ring is the same as the width of the limiting ring gap.

[0025] Furthermore, a first annular groove is provided on the side of the fixed ring near the split ring, and a toothed ring structure is integrally formed on the inner sidewall of the first annular groove;

[0026] The end of the rotating rod away from the telescopic rod is fixedly inserted through the grinding roller and extends into the first annular groove. The end of the rotating rod away from the telescopic rod is fixed with a follower gear, which is movably embedded in the first annular groove and meshes with the gear ring structure.

[0027] Furthermore, the first annular groove is an flared groove with an opening width greater than the inner width, and the end of the toothed ring structure near the opening of the first annular groove is inclined toward the outer wall of the mounting rod head.

[0028] The follower gear is a bevel gear adapted to the structure of the first ring groove and the tooth ring.

[0029] Furthermore, a first transition rounded corner is formed at the corner of the first annular groove, and an arc-shaped transition tooth segment adapted to the first transition rounded corner is formed at the corner of the toothed ring structure.

[0030] The follower gear meshes with the arc-shaped transition tooth section.

[0031] Furthermore, a second transition fillet is formed at the corner of the through annular gap and the limiting annular gap. The second transition fillet of the through annular gap is adapted to the small diameter ring, and the second transition fillet of the limiting annular gap is adapted to the large diameter ring.

[0032] Furthermore, the drive mechanism includes:

[0033] The drive motor is fixed to the support plate, and the output shaft of the drive motor rotates through the support plate.

[0034] The transmission gear has multiple transmission gears, one of which is fixedly sleeved on the motor output shaft, and several transmission gears mesh around the circumference of the other transmission gear.

[0035] The drive shaft is also provided in multiple ways and is rotatably embedded in the main rod body. Both ends of the multiple drive shafts are fixedly fitted with drive gears.

[0036] Among them, multiple transmission gears and multiple transmission shafts form a continuous and repeating transmission component, and some of the transmission gears are rotatably embedded in the main rod body;

[0037] The power output shaft has one end fixed to the transmission gear closest to the mounting rod head. The power output shaft is rotatably embedded in the end of the main rod and the mounting rod head. The other end of the power output shaft passes through the mounting rod head and is fixed to the drive short shaft.

[0038] The carrier disk includes:

[0039] The limiting plate is fixed on the frame. A V-shaped support plate is fixed on the side of the turntable in the middle of the limiting plate near the laser cutting mechanism. The inner side of the V-shaped support plate slides against the outer wall of the pipe.

[0040] The movable plate is slidably connected to the frame and is located on the side of the limiting plate away from the laser cutting mechanism.

[0041] Among them, the end of the main rod is fixed through the middle turntable of the movable disk, and the middle of the bearing rod also slides through the through hole in the middle of the limit disk turntable. The drive motor is fixed to the side of the movable disk away from the limit disk.

[0042] Linear actuator drives the movable disk and V-shaped tray to slide laterally along the frame.

[0043] Compared with the prior art, the advantages of this invention are:

[0044] 1. This solution uses a drive mechanism and a transmission mechanism to drive the grinding roller to move circumferentially around the mounting rod head. Simultaneously, the improved fixed ring and split ring structure allow the grinding roller to rotate along its own axis while moving circumferentially. This enables the grinding roller to rotate circumferentially inside the pipe, grinding away burrs. The grinding during roller rotation is more thorough, removing burrs circumferentially. Compared to transverse scraping, circumferential grinding is more effective at removing burrs and also provides internal support for the pipe, maintaining its stability during processing.

[0045] 2. This solution uses the rotation of the rotating rod to drive the follower gear. Since the follower gear meshes with the gear ring structure, it also rotates during the rotation of the rotating rod. This, in turn, drives the grinding roller to rotate, allowing the grinding roller to move circumferentially along the inner wall of the pipe and rotate along its own axis. This allows the grinding roller to better grind and remove burrs inside the pipe, resulting in a better deburring effect.

[0046] Meanwhile, the inclined toothed ring structure can prevent burrs and debris from getting stuck. Burrs and debris that enter the toothed ring structure will slide off its surface, which helps to ensure the normal meshing of the toothed ring structure and the follower gear, reduces the probability of accelerated wear or damage to the follower gear and toothed ring structure due to burrs and debris, and ensures the reliability of the equipment.

[0056] The technical solutions will now be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention.

[0057] First implementation method:

[0058] Please see Figures 1-7 A highly adaptable pipe cutting machine includes a frame 1 and a feeding mechanism 11, a positioning mechanism 12 and a laser cutting mechanism 13 arranged above it. A bearing plate 2 is arranged on the frame 1, and a bearing rod 3 that can be inserted into the inner cavity of the pipe is arranged in the middle of the bearing plate 2. L-shaped cantilever arms 8 for auxiliary support of the pipe are installed on both the front and rear sides of the frame 1.

[0059] The load-bearing rod 3 includes a main rod body 31 with the same length and width as the inner side of the pipe and an installation rod head 32 integrally formed at the front end of the main rod body 31, with a gap formed between the periphery of the installation rod head 32 and the periphery of the pipe.

[0060] An intercepting ring assembly 4 is installed on the mounting rod head 32. The intercepting ring assembly 4 includes a fixed ring 41 and a split ring 42. The fixed ring 41 is fixedly sleeved on the end of the mounting rod head 32 near the main rod body 31. The split ring 42 has a through ring gap 421 in the middle that divides the split ring 42 into inner and outer rings. The inner ring of the split ring 42 is fixedly sleeved on the end of the mounting rod head 32, and the outer ring of the split ring 42 is movably sleeved on the outside of the inner ring of the fixed ring 41 through a movable support.

[0061] When performing drilling and cutting operations, the pipe is first fixed on the frame 1 by the cooperation of the bearing rod 3, the feeding mechanism 11 and the positioning mechanism 12, so that the processing position (drilling position or cutting position) of the pipe is directly below the laser cutting mechanism 13. At the same time, the fixing ring 41 and the split ring 42 are placed on both sides of the processing position of the pipe. Then, the laser cutting mechanism 13 is used to process and cut the pipe, which can limit the debris generated during drilling or cutting and prevent the debris from scattering.

[0062] A grinding roller 5 is movably installed between the fixed ring 41 and the split ring 42, and the periphery of the grinding roller 5 is in contact with the inner wall of the pipe.

[0063] The bearing plate 2, the main rod 31, and the mounting rod head 32 are all equipped with a transmission mechanism 6 and a drive mechanism 7 that drive the grinding roller 5 to move circumferentially along the mounting rod head 32. Based on the above connection relationship, combined with... Figure 1 , Figure 2 as well as Figure 5 It can be seen that after processing, the grinding roller 5 is driven to move circumferentially along the mounting rod head 32 by the action of the drive mechanism 7 and the transmission mechanism 6, so that the grinding roller 5 can rotate circumferentially inside the pipe and grind the burrs inside the pipe. The grinding when the grinding roller 5 rotates is more thorough and can remove burrs from the circumferential direction. Compared with the transverse scraping operation, the circumferential grinding has a better effect on deburring and can also provide inner support for the pipe, thus maintaining the stability of the pipe during processing.

[0064] Furthermore, the transmission mechanism 6 includes a drive short shaft 61, a telescopic rod 62, a rotating rod 63, and a limiting rotating sleeve 64. The drive short shaft 61 is fixed to the output end of the drive mechanism 7 and is located at the front end of the mounting rod head 32.

[0065] One end of the telescopic rod 62 is fixed to the periphery of the drive short shaft 61, and the movable end of the telescopic rod 62 extends outward toward the mounting rod head 32;

[0066] The rotating rod 63 is rotatably inserted into the movable end of the telescopic rod 62, and the rotating rod 63 rotates through the annular gap 421 and is fixed to the grinding roller 5.

[0067] The limiting rotating sleeve 64 is a movable support component. The limiting rotating sleeve 64 is rotatably sleeved on the rotating rod 63 and is movably embedded in the through annular gap 421.

[0068] The limiting rotating sleeve 64 includes a small diameter ring 641 and a large diameter ring 642. The small diameter ring 641 is rotatably sleeved on the rotating rod 63. The outer diameter of the small diameter ring 641 is the same as the width of the through annular gap 421.

[0069] The large diameter ring 642 and the small diameter ring 641 are integrally formed, and the diameter of the large diameter ring 642 is larger than the diameter of the small diameter ring 641;

[0070] Among them, the split ring 42 is also provided with a limiting ring gap 422, which is connected to the through ring gap 421. The width of the limiting ring gap 422 is greater than the width of the through ring gap 421. The limiting ring gap 422 is located in the middle of the through ring gap 421. The large diameter ring 642 is movably embedded in the limiting ring gap 422, and the outer diameter of the large diameter ring 642 is the same as the width of the limiting ring gap 422.

[0071] Based on the above structure, when the short shaft 61 rotates, it drives the telescopic rod 62 to rotate. When the telescopic rod 62 rotates, it drives the rotating rod 63 to move along the through annular gap 421. When the rotating rod 63 moves, it drives the limiting rotating sleeve 64 to roll inside the through annular gap 421. The large diameter ring 642 and the small diameter ring 641 can limit and support the inner and outer rings of the split ring 42, making the structure of the split ring 42 stable and able to meet the movement requirements of the rotating rod 63. When the rotating rod 63 rotates, it can drive the grinding roller 5 to move synchronously, so that the grinding roller 5 moves in contact with the inner wall of the pipe and grinds the inner wall of the pipe, removing burrs from the pipe opening and cut, and achieving a good deburring effect.

[0072] Furthermore, a first annular groove 411 is provided on the side of the fixed ring 41 near the split ring 42, and a toothed ring structure 412 is integrally formed on the inner wall of the first annular groove 411.

[0073] The end of the rotating rod 63 away from the telescopic rod 62 is fixedly inserted through the grinding roller 5 and extends into the first annular groove 411. The end of the rotating rod 63 away from the telescopic rod 62 is fixed with a follower gear 65, which is movably embedded in the first annular groove 411 and meshes with the toothed ring structure 412.

[0074] The first annular groove 411 is an flared groove with an opening width greater than the inner width, and the toothed ring structure 412 is inclined towards the outer wall of the mounting rod head 32 at one end near the opening of the first annular groove 411.

[0075] The follower gear 65 is a bevel gear adapted to the first ring groove 411 and the tooth ring structure 412;

[0076] Based on the above structure, when the rotating rod 63 moves, it also drives the follower gear 65 to move. Since the follower gear 65 meshes with the gear ring structure 412, the follower gear 65 also rotates during the movement with the rotating rod 63. This drives the grinding roller 5 to rotate through the rotating rod 63, so that the grinding roller 5 can move circumferentially along the inner wall of the pipe and also rotate along its own axis (the same as the axis of the rotating rod 63). This allows the grinding roller 5 to better grind and remove burrs inside the pipe, resulting in a better deburring effect.

[0077] Meanwhile, the inclined toothed ring structure 412 can prevent burrs and debris from getting stuck. Burrs and debris that enter the toothed ring structure 412 will slide off its surface, which helps to ensure the normal meshing of the toothed ring structure 412 and the follower gear 65, reduces the probability of accelerated wear or damage to the follower gear 65 and the toothed ring structure 412 due to the presence of burrs and debris, and ensures the reliability of the equipment.

[0078] Furthermore, in order to ensure the smooth reversal of the grinding roller 5, a first transition rounded corner portion 413 is formed at the corner of the first annular groove 411, and an arc-shaped transition tooth segment adapted to the first transition rounded corner portion 413 is formed at the corner of the toothed ring structure 412, and the follower gear 65 meshes with the arc-shaped transition tooth segment.

[0079] A second transition rounded corner portion 423 is formed at the corner of the penetrating annular gap 421 and the limiting annular gap 422. The second transition rounded corner portion 423 of the penetrating annular gap 421 is adapted to the small diameter ring 641, and the second transition rounded corner portion 423 of the limiting annular gap 422 is adapted to the large diameter ring 642, thereby enabling the grinding roller 5 to smoothly complete the circumferential movement.

[0080] Furthermore, the drive mechanism 7 includes a drive motor 71, a transmission gear 72, a transmission shaft 73, and a power output shaft 74. The drive motor 71 is fixed to the support plate 2, and the motor output shaft 711 of the drive motor 71 rotates through the support plate 2.

[0081] Multiple transmission gears 72 are provided, one of which is fixedly sleeved on the motor output shaft 711, and several transmission gears 72 are meshed around the circumference of one of the transmission gears 72.

[0082] Multiple drive shafts 73 are also provided and are rotatably embedded in the main rod body 31. Both ends of the multiple drive shafts 73 are fixedly sleeved with drive gears 72.

[0083] Among them, multiple transmission gears 72 and multiple transmission shafts 73 form a continuous and repeating transmission component, and some of the transmission gears 72 are rotatably embedded in the main rod body 31.

[0084] One end of the power output shaft 74 is fixed to the transmission gear 72 closest to the mounting rod head 32. The power output shaft 74 is rotatably embedded in the end of the main rod body 31 and the mounting rod head 32. The other end of the power output shaft 74 passes through the mounting rod head 32 and is fixed to the drive short shaft 61.

[0085] Based on the above structure, after the drive motor 71 starts, it drives one of the transmission gears 72 to rotate through the motor output shaft 711. When one of the transmission gears 72 rotates, it drives several other transmission gears 72 (three in the figure) to rotate. The other transmission gears 72 then drive another set (corresponding number) of transmission gears 72 to rotate through several transmission shafts 73, and drive another transmission gear 72 whose axis coincides with that of one of the transmission gears 72 to rotate. After multiple transmissions, it drives the output shaft 74 to rotate, thereby achieving the purpose of driving the drive short shaft 61 to rotate, and finally achieving the purpose of driving the grinding roller 5 to move in the circumferential direction.

[0086] Second implementation method:

[0087] Please see Figures 1-3 A highly adaptable pipeline cutting machine, which differs from the first embodiment in that:

[0088] The carrier plate 2 includes a limiting plate 21 and a movable plate 22. The limiting plate 21 is fixed on the frame 1. A V-shaped support plate 23 is fixed on the side of the turntable in the middle of the limiting plate 21 near the laser cutting mechanism 13. The inner side of the V-shaped support plate 23 slides against the outer wall of the pipe.

[0089] The movable disk 22 is slidably connected to the frame 1, and the movable disk 22 is located on the side of the limiting disk 21 away from the laser cutting mechanism 13;

[0090] Among them, the end of the main rod 31 is fixed through the middle turntable of the movable disk 22, and the middle of the bearing rod 3 also slides through the through hole in the middle of the turntable of the limiting disk 21. The drive motor 71 is fixed to the side of the movable disk 22 away from the limiting disk 21.

[0091] Linear actuator 24 drives movable disk 22 and V-shaped support plate 23 to slide laterally along frame 1.

[0092] The specific working principle is as follows: First, the pipe is fixed on the frame 1 by the cooperation of the bearing plate 2, bearing rod 3, feeding mechanism 11 and positioning mechanism 12, so that the position of the pipe to be processed is directly below the laser cutting mechanism 13. At the same time, the fixing ring 41 and the split ring 42 are placed on both sides of the position of the pipe to be processed. Then, the laser cutting mechanism 13 is used to process and cut the pipe, which can limit the debris generated during drilling or cutting and prevent the debris from scattering.

[0093] After processing, the grinding roller 5 is driven to move circumferentially around the mounting rod head 32 by the action of the drive mechanism 7 and the transmission mechanism 6. Specifically, after the drive motor 71 starts, it drives one of the transmission gears 72 to rotate through the motor output shaft 711. When one of the transmission gears 72 rotates, it drives several other transmission gears 72 to rotate. The other transmission gears 72 then drive another set of transmission gears 72 to rotate through several transmission shafts 73, and drive another transmission gear 72 that is aligned with the axis of one of the transmission gears 72 to rotate. After multiple transmissions, it drives the output shaft 74 to rotate, thereby achieving the purpose of driving the drive short shaft 61 to rotate.

[0094] When the short shaft 61 rotates, it drives the telescopic rod 62 to rotate. When the telescopic rod 62 rotates, it drives the rotating rod 63 to move along the through annular gap 421. When the rotating rod 63 moves, it drives the limiting rotating sleeve 64 to roll within the through annular gap 421. The large-diameter ring 642 and the small-diameter ring 641 can limit and support the inner and outer rings of the split ring 42, making the structure of the split ring 42 stable and meeting the movement requirements of the rotating rod 63. When the rotating rod 63 rotates, it can drive the grinding roller 5 to move synchronously, so that the grinding roller 5 moves in contact with the inner wall of the pipe. When the rotating rod 63 moves, it also drives the follower gear 65 to move. Since the follower gear 65 meshes with the gear ring structure 412, the follower gear 65 also rotates during the movement with the rotating rod 63, thereby driving the grinding roller 5 to rotate through the rotating rod 63. This allows the grinding roller 5 to move circumferentially along the inner wall of the pipe and also rotate along its own axis, thus grinding the burrs inside the pipe.

[0095] The above description is merely a preferred embodiment of the present invention; it encompasses all the protection scope of the present invention. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solutions and improved concepts of the present invention, should be covered within the protection scope of the present invention.
