Technical Field

[0001] The invention relates to the technical field of pipe processing, and in particular to a high-efficiency pipe groove machine. Background Art

[0002] In the mechanical processing industry, it is often encountered that annular grooves are processed on pipe fittings. The main purpose of processing annular grooves is to play a role of sealing and balancing, and it may also have other functions such as positioning, fixing, and shockproofing.

[0003] Under the existing technology, the annular groove processing in the machinery industry is mostly completed by turning or milling. However, when fixing the pipe fittings, it is generally clamped by a three-jaw chuck, and then the motor drives the pipe fitting to rotate along its central axis, and then the annular groove is processed on the surface of the pipe by a turning tool or other cutting tools. However, the use of existing processing devices (lathes or milling machines, etc.) to process annular grooves on pipe fittings has great limitations. First, the staff needs to manually clamp the pipe fittings. Although there are currently three-jaw chucks that can be clamped automatically, it is still necessary to manually move the pipe fittings to the chuck position, so the processing efficiency is relatively low, and the structure of the three-jaw chuck that can be clamped automatically is relatively complex, and it may also require additional drive components to drive the clamping, resulting in its huge size and high manufacturing costs, which is not conducive to the development of enterprises; secondly, the existing processing device can only process a single pipe fitting when processing the pipe fittings, and cannot be mass-produced, resulting in low processing efficiency; finally, the existing processing device has poor matching with the production line, and cannot be processed by the previous process and transferred to the next process, which further causes low processing efficiency. Summary of the invention

[0004] One of the purposes of the present invention is to solve the problem of low processing efficiency caused by manual operation and poor matching between the existing processing device and the production line when processing pipe fittings in the prior art.

[0005] A second object of the present invention is to provide a tube processing method.

[0006] To achieve one of the above-mentioned purposes, the present invention adopts the following technical scheme: an efficient pipe trough machine, which includes: a pushing device, which can be freely telescopically moved; a first conveying mechanism, one end of which is located at a relative position of the pushing mechanism; a rotating clamping mechanism, one end of which is located at the other end of the first conveying mechanism, and the rotating clamping mechanism includes: a mounting seat, at least two mounting seats, the mounting seats have a accommodating space, and the accommodating spaces between the mounting seats are aligned with each other; a bearing, the bearing is arranged in the accommodating space; a clamping assembly, the clamping assembly is arranged in the bearing, and the clamping assembly includes: an outer cylinder, the outer cylinder has a accommodating space; an inner cylinder, the inner cylinder has a storage space, the storage space is used to store pipe fittings or provide free movement of pipe fittings, the inner cylinder is arranged in the outer cylinder, there is a gap between the inner cylinder and the outer cylinder, and the inner cylinder has a through groove The through groove connects the gap with the internal space of the inner cylinder; a transmission part, one end of the transmission part is movably connected to the inner wall of the outer cylinder; a clamping part, the other end of the transmission part is movably connected to one end of the clamping part, and the other end of the clamping part is movably connected to the wall of the through groove; a rotating device, the rotating device is installed on the mounting seat, the rotating device is connected to the outer cylinder, and the rotating device can drive the clamping assembly to rotate; a displacement part, the displacement part is located above the mounting seat; a slider, the slider is arranged above between the mounting seats, the slider is located at the side end of the displacement part, the slider can move relative to the displacement part, the displacement part can slide, and the sliding direction is perpendicular to the moving direction of the slider; a kit, the kit is connected to the slider, the kit can move up and down relative to the slider, and the kit has: a cutting piece, the cutting piece is installed on the kit; a second transmission mechanism, the second transmission mechanism is located at the other end of the rotating clamping mechanism.

[0007] In the above technical scheme, the embodiment of the present invention firstly receives and conveys the pipe fittings of the previous process through the first conveying mechanism. Secondly, the pipe fittings are pushed into the inner cylinder of the clamping assembly through the pushing device. After that, the height position of the cutting piece on the kit is adjusted according to the groove depth requirement of the pipe fitting processing. Then, the rotating device is started to drive the outer cylinder of the clamping assembly to rotate and push the transmission part to move, and further push the clamping part to move. In this process, the movement of the clamping part is limited by the connection between the clamping part and the inner cylinder, forcing the clamping part to rotate and clamp the pipe fitting with the connection between the clamping part and the inner cylinder as the center point. After the clamping part clamps the pipe fitting, the rotation of the clamping part is limited, and further forcing the clamping part to drive the inner cylinder and the pipe fitting to rotate synchronously along the movement of the outer cylinder. Then, the displacement part and the slider are moved in free directions forward, backward, left and right to realize the groove processing or cutting processing of any position of the pipe fitting. Finally, after the processing of the pipe fittings is completed, the rotating device is started again to reverse to loosen the pipe fittings. At the same time, the pushing device is started again to push the unprocessed root pipe fittings into the inner tube to press against the processed pipe fittings, and the processed pipe fittings are pushed out of the inner tube and enter the second conveying mechanism to be transported to the next process.

[0008] Furthermore, in an embodiment of the present invention, the high-efficiency pipe groove machine further includes: a guide wheel, the guide wheel is located between the clamping assembly and the second conveying mechanism, there are at least two guide wheels, there is a gap between the guide wheels, and the gap is aligned with the central axis of the inner cylinder; a rotating motor, the rotating motor is connected to the guide wheel. When the pipe is pushed away from the inner cylinder, when the pipe moves toward the gap between the guide wheels, the rotating motor is started to drive the guide wheel to rotate so as to completely drive the pipe out of the inner cylinder and enter the second conveying mechanism, so as to prevent the pipe from being unable to completely leave the inner cylinder and affect the automated processing and production.

[0009] Furthermore, in an embodiment of the present invention, the clamping assembly further includes: a guide portion, the guide portion is movably connected to the inner movability of the inner tube; an elastic portion, one end of the elastic portion is connected to the guide portion, and the other end of the elastic portion is connected to the inner tube. During the process of the pipe fitting moving into the inner tube of the clamping assembly, the pipe fitting contacts the guide portion. On the one hand, the guide portion is subjected to force, and retracts under the action of the elastic portion while clamping the pipe fitting to a certain extent. The weight of the pipe fitting can strengthen the resistance of the inner tube in the rotation direction, preventing the inner tube from being unable to resist one end of the clamping portion, resulting in the clamping portion being unable to rotate with the connection position of the clamping portion and the inner tube as the center point, resulting in the inability to clamp the pipe fitting; on the other hand, the guide portion guides the position of the pipe fitting, so that each time the pipe fitting enters the inner tube, its center line position remains unchanged, avoiding the center position change when the clamping portion clamps the pipe fitting, resulting in the need to adjust the height position of the cutting piece each time.

[0010] Furthermore, in an embodiment of the present invention, the clamping portion has a curved surface, and the curved surface matches the surface of the pipe.

[0011] Furthermore, in the embodiment of the present invention, the corners of the clamping part are arc chamfered to remove the sharp corners of the clamping part, so as to avoid the protruding sharp corners scratching the surface of the pipe fitting during the rotation of the clamping part, thereby affecting the quality of the pipe fitting.

[0012] Furthermore, in the embodiment of the present invention, the transmission part is an arc-shaped rod, and the arc surface of the transmission part is adapted to the inner wall of the outer tube. The arc-shaped transmission part can fit with the inner tube of the outer tube, and can make full use of the gap space between the inner tube and the outer tube, which is conducive to expanding the storage space of the inner tube to accommodate more pipes of different specifications and sizes.

[0013] Furthermore, in an embodiment of the present invention, the pushing device is a cylinder.

[0014] Furthermore, in an embodiment of the present invention, the rotating device is a motor.

[0015] Furthermore, in an embodiment of the present invention, the first conveying mechanism is a conveyor belt having a groove, which is an arc-shaped groove. The groove accommodates the pipe fittings, so that the position of the pipe fittings can be limited when the first conveying mechanism conveys the pipe fittings, thereby preventing the pipe fittings from being unable to accurately enter the inner barrel during the feeding process.

[0016] Furthermore, in an embodiment of the present invention, the second conveying mechanism is a conveyor belt.

[0017] Furthermore, in an embodiment of the present invention, the kit further comprises a tightening nut, and the kit is fixedly mounted on the slider by the tightening nut.

[0018] Furthermore, in an embodiment of the present invention, the high-efficiency pipe slot machine also includes: a dust-proof part, which is arranged above the mounting seat, and the dust-proof part has: a slide groove; a telescopic part, which is located in the slide groove, and one end of the telescopic part is connected to the slide groove; a coupling part, which is located in the slide groove, and the other end of the telescopic part is connected to the coupling part, and the coupling part has: a concave part, and the concave part has a coupling space; a convex part, which is connected to the concave part, and the volume of the convex part is smaller than the coupling space, and the convex part can move relative to the coupling space. The contact part of the displacement part slides in the slide groove of the dust-proof part to achieve movement, and the coupling part in the slide groove seals the slide groove. When the contact part contacts the coupling part, the coupling part is forced to retract and move to provide space for the contact part to move. When the contact part does not contact the coupling part, the coupling part is reset and re-seals the slide groove under the elastic action of the telescopic part, so that dust and other particles can be prevented from accumulating in the slide groove, causing the displacement part to shake when sliding, which is not conducive to the processing of pipe fittings. At the same time, in order to prevent the contact piece from blocking the movement of the contact piece by the engaging piece that is not in contact with the contact piece (the engaging piece adjacent to the contact piece), the engaging piece in contact with the contact piece is forced to retract while the convex part of the engaging piece moves a certain distance in the concave part of the adjacent engaging piece. After moving a certain distance, the convex part contacts the wall of the concave part, so that the engaging piece drives the adjacent engaging piece to retract, so that when one engaging piece retracts, it drives the adjacent engaging piece to retract a certain distance, forming a step shape, which is conducive to the contact piece to move freely step by step on the engaging piece.

[0019] Furthermore, in an embodiment of the present invention, the displacement portion has a contact member having a raised arc surface, and the raised arc surface of the contact member contacts the stepped engagement member, wherein the arc surface is conducive to guiding, and can realize smooth movement of the contact member on the engagement member to avoid being stuck.

[0020] Furthermore, in the embodiment of the present invention, the displacement part further comprises: a driving device; and a gear, wherein the gear is connected to the driving device.

[0021] Furthermore, in an embodiment of the present invention, the slider is an electric slider.

[0022] Furthermore, in an embodiment of the present invention, there are at least two displacement parts, a guide rail is provided between the displacement parts, the guide rail is fixedly connected to the displacement parts, a slider is mounted on the guide rail, and the slider is equivalent to the guide rail and can slide along the direction of the guide rail.

[0023] Furthermore, in the embodiment of the present invention, the dust shielding portion further has tooth grooves.

[0024] Furthermore, in an embodiment of the present invention, the top of the dust-shielding portion is an arc surface, the arc surface faces upward, the side end of the dust-shielding portion has a blocking surface, the slide groove is arranged in the middle area of ​​the dust-shielding portion, and the horizontal height of the slide groove is higher than the blocking surface. First, the upper periphery of the slide groove is in a semi-enclosed state, which can prevent dust from falling into the slide groove to the greatest extent, and prevent excessive dust and other particles in the slide groove, which causes the displacement portion to shake when sliding, which is not conducive to pipe processing. Secondly, the arc-shaped top of the dust-shielding portion can guide dust and other particles to prevent dust and other particles from accumulating on the dust-shielding portion. Finally, the blocking surface at the side end of the slide groove can, to a certain extent, prevent dust and other particles from falling into the slide groove under the action of airflow.

[0025] Furthermore, in the embodiment of the present invention, hooks are provided at the upper and lower ends of the convex part to prevent the convex part from moving out of the concave part.

[0026] Furthermore, in an embodiment of the present invention, the telescopic member is a spring.

[0027] Furthermore, in an embodiment of the present invention, the driving device is a motor.

[0028] The beneficial effects of the present invention are:

[0029] The present invention drives the pipe to rotate by the clamping assembly and realizes automatic clamping of the pipe. In this process, the two steps of rotation and clamping are continuous movements, and the time to realize the two steps is almost synchronous, and no manual operation is required, which is greatly beneficial to reducing the time of installing pipes and speeding up processing efficiency. At the same time, the present invention adopts a one-in-one-out method to move the pipe in relative directions, so that the position of the pipe does not need to be turned, which is greatly beneficial to docking with a linear production line and has a strong match with the production line. Finally, the present invention does not require manual operation in the process of feeding, processing, and discharging, which is conducive to the development of automation.

[0030] To achieve the second objective, the present invention adopts the following technical solution: a tube processing method, comprising the following steps:

[0035] Rotation: The rotating device rotates continuously, and the rotation of the clamping part is restricted during the process of the clamping part clamping the pipe fitting, so that the clamping part cannot rotate alone, and the clamping part is forced to drive the inner tube and the pipe fitting to rotate synchronously along the movement of the outer tube;

[0036] Processing: the displacement part and the slider can move freely in the front, back, left, and right directions to achieve groove processing or cutting processing at any position of the pipe;

[0037] After the pipe is processed, the rotating device is started to reverse to loosen the pipe, and then the pushing device is started to push the unprocessed pipe into the inner tube. At the same time, the pushed pipe presses against the processed pipe, and the processed pipe is pushed away from the inner tube and enters the second conveying mechanism;

[0038] Transfer and start the second conveying mechanism to convey the pipe to the next process, and then repeat the above steps as needed to complete the automated processing and production.

[0039] Furthermore, in an embodiment of the present invention, in the feeding step, when the pipe moves into the inner tube of the clamping assembly, the pipe contacts the guide portion, which is stressed and retracts under the action of the elastic portion while clamping the pipe to a certain extent.

[0040] Furthermore, in an embodiment of the present invention, in the feeding step, when the pipe moves into the inner barrel of the clamping assembly, the pipe contacts the guide portion, and the guide portion guides the position of the pipe so that each time the pipe enters the inner barrel, its centerline position remains unchanged.

[0041] Furthermore, in an embodiment of the present invention, in the processing step, the displacement part is driven by a motor.

[0042] Furthermore, in an embodiment of the present invention, in the processing step, the slider is driven electrically.

[0043] Furthermore, in an embodiment of the present invention, in the processing step, the contact piece of the displacement part slides in the slide groove of the dust shielding part to achieve movement, the coupling piece in the slide groove seals the slide groove, and when the contact piece contacts the coupling piece, the coupling piece is forced to retract and move to provide space for the contact piece to move; when the contact piece is not in contact with the coupling piece, the coupling piece is reset under the elastic action of the telescopic piece.

[0044] Furthermore, in an embodiment of the present invention, in a processing step, the displacement portion moves in a slide groove of the dust shielding portion, and when a coupling piece in the slide groove contacts a contact piece of the displacement portion, the coupling piece is forced to retract, and while the coupling piece retracts, a convex portion of the coupling piece moves a certain distance in a concave portion of an adjacent coupling piece, and after moving a certain distance, the convex portion contacts a wall surface of the concave portion, so that the coupling piece drives the adjacent coupling piece to retract, so that when one coupling piece retracts, it drives its adjacent coupling piece to retract a certain distance, forming a step shape, and the movement is achieved by the raised arc surface of the contact piece contacting the stepped coupling piece.

[0045] Furthermore, in an embodiment of the present invention, in the discharging step, when the pipe is pushed out of the inner cylinder and moves toward the gap between the guide wheels, the rotating motor is started to drive the guide wheels to rotate so as to completely drive the pipe out of the inner cylinder and enter the second conveying mechanism.

However, it is obvious that for those of ordinary skill in the art, the embodiments may not be limited to these specific details in practice. In some instances, known pipe processing methods and structures are not described in detail to avoid making the embodiments unnecessarily difficult to understand. In addition, all embodiments may be used in combination with each other.

[0076] Embodiment 1:

[0077] A high-efficiency pipe slot machine, wherein Figure 1 , 2 As shown, it includes: a pushing device 1, a first conveying mechanism 2, a rotating clamping mechanism 3, a rotating device 6, a displacement part 10, a slider 11, a kit 111, and a second conveying mechanism 7.

[0078] The pushing device 1 can be freely telescopic and movable. The first conveying mechanism 2 is located at the right end position of the pushing mechanism.

[0079] The rotating clamping mechanism 3 is located at the right end of the first conveying mechanism 2, and the rotating clamping mechanism 3 includes: a mounting seat 4, a bearing (not shown), and a clamping assembly 5. There are at least two mounting seats 4, and the mounting seats 4 have a receiving space, and the receiving spaces between the mounting seats 4 are aligned with each other. The bearing is arranged in the receiving space.

[0080] The clamping assembly 5 is arranged in the bearing, such as Figure 4-7As shown, the clamping assembly 5 includes: an outer cylinder 501, an inner cylinder 502, a transmission part 503, and a clamping part 504. The outer cylinder 501 has a storage space. The inner cylinder 502 has a storage space, which is used to store pipe fittings or provide free movement of pipe fittings. The inner cylinder 502 is arranged in the outer cylinder 501, and there is a gap between the inner cylinder 502 and the outer cylinder 501. The inner cylinder 502 has a through groove, and the through groove connects the gap with the internal space of the inner cylinder 502. The upper end of the transmission part 503 is movably connected to the inner wall of the outer cylinder 501. The lower end of the transmission part 503 is movably connected to the left end of the clamping part 504, and the right end of the clamping part 504 is movably connected to the wall surface of the through groove.

[0081] The rotating device 6 is installed on the mounting seat 4 . The rotating device 6 is connected to the outer cylinder 501 . The rotating device 6 can drive the clamping assembly 5 to perform a rotating motion.

[0082] like Figure 1-3 As shown, the displacement part 10 is located above the mounting seat 4. The slider 11 is arranged above the mounting seat 4, and the slider 11 is located at the side end of the displacement part 10. The slider 11 can move relatively toward the displacement part 10, and the displacement part 10 can slide, and the sliding direction is perpendicular to the moving direction of the slider 11. The kit 111 is connected to the slider 11, and the kit 111 can move up and down relative to the slider 11. The kit 111 has a cutting piece 112, and the cutting piece 112 is installed on the kit 111. The second transmission mechanism 7 is located at the right end of the rotating clamping mechanism 3.

[0083] Implementation steps: First, the first conveying mechanism 2 is used to receive and transport the pipe fittings of the previous process. Secondly, the pushing device 1 is used to push the pipe fittings into the inner cylinder 502 of the clamping assembly 5. Then, according to the groove depth requirements of the pipe fittings, the height position of the cutting piece 112 on the kit 111 is adjusted. Then, the rotating device 6 is started to drive the outer cylinder 501 of the clamping assembly 5 to rotate and push the transmission part 503 to move, and further push the clamping part 504 to move. In this process, the movement of the clamping part 504 is limited by the connection between the clamping part 504 and the inner cylinder 502, forcing the clamping part 504 to rotate and clamp the pipe fitting with the connection between the clamping part 504 and the inner cylinder 502 as the center point. After the clamping part 504 clamps the pipe fitting, the rotation of the clamping part 504 is limited, and further the clamping part 504 is forced to drive the inner cylinder 502 and the pipe fitting to rotate synchronously along the movement of the outer cylinder 501. Then, the displacement part 10 and the slider 11 are moved in free directions forward, backward, left and right to realize the groove processing or cutting processing of any position of the pipe fitting. Finally, after the processing of the pipe fittings is completed, the rotating device 6 is started again to reverse to loosen the pipe fittings, and the pushing device 1 is started again to push the unprocessed root pipe fittings into the inner cylinder 502 to press against the processed pipe fittings, and the processed pipe fittings are pushed out of the inner cylinder 502 and enter the second conveying mechanism 7 to be transported to the next process.

[0084] Specifically, Figure 1 ,2 As shown, the high-efficiency pipe groove machine also includes: a guide wheel 8 and a rotating motor. The rotating motor is connected to the guide wheel 8. The guide wheel 8 is located between the clamping assembly 5 and the second conveying mechanism 7. There are at least two guide wheels 8, and there is a gap between the guide wheels 8. The gap is aligned with the central axis of the inner cylinder 502. When the pipe is pushed away from the inner cylinder 502 and moves toward the gap between the guide wheels 8, the rotating motor is started to drive the guide wheel 8 to rotate so as to completely drive the pipe to separate from the inner cylinder 502 and enter the second conveying mechanism 7, so as to prevent the pipe from being unable to completely separate from the inner cylinder 502 and affecting the automated processing and production.

[0085] Specifically, Figure 8 , 9 As shown, the clamping assembly 5 further includes: a guide portion 505 and an elastic portion 506. The guide portion 505 is movably connected to the inner part of the inner tube 502. One end of the elastic portion 506 is connected to the guide portion 505, and the other end of the elastic portion 506 is connected to the inner tube 502. When the pipe moves into the inner tube 502 of the clamping assembly 5, the pipe contacts the guide portion 505. On the one hand, the guide portion 505 is subjected to force, and retracts under the action of the elastic portion 506 while clamping the pipe to a certain extent. The weight of the pipe can strengthen the resistance of the inner tube 502 in the rotation direction, preventing the inner tube 502 from failing to resist the right end of the clamping portion 504, resulting in the clamping portion 504 being unable to rotate with the connection position of the clamping portion 504 and the inner tube 504 as the center point, resulting in the inability to clamp the pipe. On the other hand, the guide part 505 guides the position of the pipe so that each time the pipe enters the inner tube 502, its center line position remains unchanged, avoiding the center position change when the clamping part 504 clamps the pipe, resulting in the need to adjust the height position of the cutting piece 112 each time.

[0086] Specifically, Figure 5 , 6 As shown in Figures 7 and 8, the clamping portion 504 has a curved surface, which matches the surface of the pipe.

[0087] Specifically, the corners of the clamping portion 504 are chamfered with arcs. The sharp corners of the clamping portion 504 are removed to prevent the protruding sharp corners from scratching the surface of the pipe during the rotation of the clamping portion 504, thereby affecting the quality of the pipe.

[0088] Specifically, the transmission part 503 is an arc-shaped rod, and the arc surface of the transmission part 503 is adapted to the inner wall of the outer cylinder 501. The arc-shaped transmission part 503 can fit with the outer cylinder 501 and the inner cylinder 502, and can make full use of the gap space between the inner cylinder 502 and the outer cylinder 501, which is conducive to expanding the storage space of the inner cylinder 502 to accommodate more pipes of different specifications and sizes.

[0089] Specifically, the pushing device 1 is a cylinder.

[0090] Specifically, the rotating device 6 is a motor.

[0091] Specifically, the first conveying mechanism 2 is a conveyor belt having a groove 21, which is an arc-shaped groove. The groove 21 accommodates the pipe, and can limit the position of the pipe when the first conveying mechanism 2 conveys the pipe, so as to prevent the pipe from failing to accurately enter the inner cylinder 502 during the feeding process.

[0093] Specifically, the kit 111 further has a tightening nut 113 , and the kit 111 is fixedly mounted on the slider 11 by tightening the nut 113 .

[0094] Specifically, Figure 1 , 10 As shown, the high-efficiency pipe slot machine also includes a dust-proof part 9, which is arranged above the mounting seat 4. Fig.12 , 13 As shown, the dust shielding part 9 comprises: a slide groove, a telescopic member 92, and a joint member 91. The telescopic member 92 is located in the slide groove, and one end of the telescopic member 92 is connected to the slide groove. The joint member 91 is located in the slide groove, and the other end of the telescopic member 92 is connected to the joint member 91. Fig.14 , 15 As shown, the coupling member 91 has a recess 911 and a protrusion 912, and the recess 911 has a coupling space. The protrusion 912 is connected to the recess 911, and the volume of the protrusion 912 is smaller than the coupling space, and the protrusion 912 can move relative to the coupling space. The contact member 101 of the displacement portion 10 slides in the slide groove of the dust-proof portion 9 to achieve movement, and the coupling member 91 in the slide groove seals the slide groove. When the contact member 101 contacts the coupling member 91, the coupling member 91 is forced to retract and move to provide space for the contact member 101 to move. When the contact member 101 is not in contact with the coupling member 91, the coupling member 91 is reset and re-seals the slide groove under the elastic action of the telescopic member 92, so that dust and other particles can be prevented from accumulating in the slide groove, causing the displacement portion 10 to shake when sliding, which is not conducive to the processing of the pipe fittings. At the same time, in order to prevent the contact member 101 from moving and the engaging member 91 that is not in contact with the contact member 101 (the engaging member 91 adjacent to the contact member 101) blocking the movement of the contact member 101, the engaging member 91 in contact with the contact member 101 is forced to retract, while the convex portion 912 of the engaging member 91 moves a certain distance in the concave portion 911 of the adjacent engaging member 91. After moving a certain distance, the convex portion 912 contacts the wall of the concave portion 911, so that the engaging member 91 drives the adjacent engaging member 91 to retract, so that when one engaging member 91 retracts, it drives the adjacent engaging member 91 to retract a certain distance, forming a step shape, which is conducive to the contact member 101 to move freely step by step on the engaging member 91.

[0095] Specifically, Fig.14 , 15As shown, the displacement part 10 has a contact member 101, and the contact member 101 has a raised arc surface. The raised arc surface of the contact member 101 contacts the stepped engagement member 91, wherein the arc surface is conducive to guiding, so that the contact member 101 can move smoothly on the engagement member 91 and avoid being stuck.

[0096] More specifically, if Fig.11 As shown, the displacement part 10 further comprises a driving device 12 and a gear 13, and the gear 13 is connected to the driving device 12.

[0098] Specifically, there are at least two displacement parts 10, a guide rail is arranged between the displacement parts 10, the guide rail is fixedly connected to the displacement parts 10, and the slider 11 is installed on the guide rail. The slider 11 is equivalent to the guide rail and can slide along the direction of the guide rail.

[0099] More specifically, if Figure 1 , 10 As shown, the top of the dust-shielding portion 9 is an arc surface, which faces upward. The two side ends of the dust-shielding portion 9 have blocking surfaces. The slide groove is arranged in the middle area of ​​the dust-shielding portion 9, and the horizontal height of the slide groove is higher than the blocking surface. First, the upper periphery of the slide groove is in a semi-enclosed state, which can prevent dust from falling into the slide groove to the greatest extent, and prevent excessive dust and other particles in the slide groove, which causes the displacement portion 10 to shake when sliding, which is not conducive to pipe processing. Secondly, the arc-shaped top of the dust-shielding portion 9 can guide dust and other particles to prevent dust and other particles from accumulating on the dust-shielding portion 9. Finally, the blocking surface at the side end of the slide groove can, to a certain extent, prevent dust and other particles from falling into the slide groove under the action of airflow.

[0100] More specifically, hooks (not shown) are provided at both ends of the convex portion 912 to prevent the convex portion 912 from moving out of the concave portion 911 .

[0101] More specifically, the telescopic member 92 is a spring.

[0102] More specifically, the driving device 12 is a motor.

At the same time, the present invention adopts a one-in-one-out method to move the pipe in relative directions, so that the position of the pipe does not need to be turned, which is greatly beneficial to docking with a linear production line and has a strong match with the production line. Finally, the present invention does not require manual operation in the process of feeding, processing, and discharging, which is conducive to the development of automation.

[0105] A tube processing method comprises the following steps:

[0106] Transporting: Start the first transport mechanism 2 to transport the pipe from the previous process to a position opposite to the pushing device 1.

[0107] Feeding, starting the pushing device 1, the pushing device 1 pushes the pipe to move into the inner cylinder 502 of the clamping assembly 5, so that both ends of the pipe are located in the inner cylinder 502.

[0108] Adjustment: According to the groove depth required to be processed on the pipe fitting, the height position of the tightening nut 113 adjustment kit 111 is adjusted to further adjust the height of the cutting piece 112.

[0109] Clamping, start the rotating device 6 to drive the clamping assembly 5 to rotate, the outer cylinder 501 of the rotating clamping assembly 5 pushes the transmission part 503 to move, and the transmission part 503 pushes the clamping part 504 to move, and at the same time, the connection between the clamping part 504 and the inner cylinder 502 presses against the clamping part 504, forcing the clamping part 504 to rotate with the connection between the clamping part 504 and the inner cylinder 502 as the center point, and the clamping part 504 continues to rotate until it clamps the pipe in the inner cylinder 502, thereby completing the clamping of the pipe.

[0110] Rotate, the rotating device 6 rotates continuously, and the rotation of the clamping part 504 is restricted during the process of clamping the pipe, so that the clamping part 504 cannot rotate alone, forcing the clamping part 504 to drive the inner tube 502 and the pipe to rotate synchronously along the movement of the outer tube 501.

[0111] Processing, through the displacement part 10 and the slider 11 to move freely in the front, back, left and right directions, to achieve groove processing or cutting processing at any position of the pipe.

[0112] After the pipe is processed, the rotating device 6 is started to reverse to loosen the pipe, and then the pushing device 1 is started to push the unprocessed pipe into the inner tube 502. At the same time, the pushed-in pipe presses against the processed pipe, pushing the processed pipe away from the inner tube 502 and into the second conveying mechanism 7.

[0113] Transfer, start the second conveying mechanism 7 to convey the pipe to the next process, and then repeat the above steps according to demand to complete the automated processing and production.

[0114] Specifically, in the feeding step, when the pipe moves into the inner cylinder 502 of the clamping assembly 5, the pipe contacts the guide portion 505, the guide portion 505 is stressed, and retracts under the action of the elastic portion 506 while clamping the pipe to a certain extent.

[0115] Specifically, in the feeding step, when the pipe moves into the inner cylinder 502 of the clamping assembly 5, the pipe contacts the guide portion 505, and the guide portion 505 guides the position of the pipe, so that each time the pipe enters the inner cylinder 502, its centerline position remains unchanged.

[0116] Specifically, in the processing step, the displacement part 10 is driven by a motor.

[0117] Specifically, during the processing step, the slider 11 is driven electrically.

[0118] Specifically, in the processing step, the contact piece 101 of the displacement portion 10 slides in the slide groove of the dust shielding portion 9 to achieve movement, and the coupling piece 91 in the slide groove seals the slide groove. When the contact piece 101 contacts the coupling piece 91, the coupling piece 91 is forced to retract and move to provide space for the contact piece 101 to move. When the contact piece 101 is not in contact with the coupling piece 91, the coupling piece 91 is reset under the elastic action of the telescopic piece 92.

[0119] Specifically, in the processing step, the displacement part 10 moves in the slide groove of the dust shielding part 9, and when the coupling member 91 in the slide groove contacts the contact member 101 of the displacement part 10, the coupling member 91 is forced to retract, and while the coupling member 91 retracts, the convex portion 912 of the coupling member 91 moves a certain distance in the concave portion 911 of the adjacent coupling member 91. After moving a certain distance, the convex portion 912 contacts the wall surface of the concave portion 911, so that the coupling member 91 drives the adjacent coupling member 91 to retract, so that when one coupling member 91 retracts, it drives the adjacent coupling member 91 to retract a certain distance, forming a step shape, and the movement is achieved by the raised arc surface of the contact member 101 contacting the stepped coupling member 91.

[0120] Specifically, in the discharging step, when the pipe is pushed away from the inner cylinder 502 and moves toward the gap between the guide wheels 8, the rotating motor is started to drive the guide wheels 8 to rotate so as to completely drive the pipe out of the inner cylinder 502 and enter the second conveying mechanism 7.
