Description

Technical Field

[0001] The present invention relates to the technical field of ship pipe system manufacturing and processing equipment, and particularly to a ship pipe fitting processing and production equipment and its production method. Background Technique

[0002] The production of ship pipe systems is an important link in the shipbuilding process and one of the important factors affecting the shipbuilding progress. Existing ship pipe system processing equipment usually adopts the production process of "bending first and then welding". The pipes are cut by cutting equipment according to the design requirements. After cutting, the pipes are separated by a separation mechanism and moved to a pipe bender by a handling device. First, the pipes are bent into shape on the pipe bender, and then after calibration and positioning of the pipes and flanges on the manual pipe alignment platform, welding is carried out manually.

[0003] However, when determining the cutting length of the straight pipe section in traditional ship pipe system processing equipment, due to the errors and springback during bending, a certain process allowance usually needs to be added to the cutting length. The pipes need to be cut again during assembly, wasting raw materials and reducing production efficiency. After bending, it is difficult to assemble the pipes on the pipe alignment machine. The flanges need to be manually assembled on the bent pipes, and the relative angles of the flange holes on both sides of the pipes need to be calibrated manually to ensure that the flanges on both sides of the bent pipe will not be misaligned after welding, so that the flanges can be smoothly connected during pipe assembly to avoid difficulties in connection or poor sealing due to misaligned bolt holes. The welding of the flanges also needs to be carried out on the bent pipes. The bending of the pipes and the calibration of the flanges make it difficult to use an automatic flange welding machine for welding the pipes and flanges, resulting in low pipe alignment and welding efficiency and unguaranteed quality. Summary of the Invention

[0004] In view of the deficiencies existing in the use of existing ship pipe system processing equipment in the background technique, the present invention provides a ship pipe fitting processing and production equipment and its production method, which have the advantages of facilitating flange calibration and welding, ensuring welding quality, and being applicable to different pipe diameters, and solve the technical problems proposed in the above background technique.

The sliding groove is a straight groove.

[0010] Preferably, a fixing seat is fixedly connected to one end of the robotic arm. A rotating shaft is rotatably clamped inside one side of the fixing seat. A clamping mechanism for clamping the flange is fixedly connected to one side of the rotating shaft. An identification mechanism for identifying the flange model is arranged on the robotic arm.

[0011] Preferably, a friction plate is slidably sleeved inside the fixed seat. One side of the rotating shaft close to the friction plate is a friction surface. An electromagnet is fixedly arranged on one side inside the fixed seat. An adjusting spring for providing a frictional thrust to the friction plate is movably sleeved inside the fixed seat. One side of the friction plate is fixedly connected with a permanent magnet corresponding to the electromagnet, and the acting force between the permanent magnet and the electromagnet is an attractive force.

[0012] Preferably, the diameter of the positioning rod is adapted to the diameter of the bolt holes on the flange. One side of the rod body of the positioning rod is conical. A sleeve is slidably sleeved outside the positioning rod. One side of the positioning rod is fixedly connected with a first conductive block, and one side of the sleeve is fixedly connected with an outer spring;

[0013] Both the inner spring and the outer spring are insulating springs. The diameter of the sleeve is larger than the diameter of the flange bolt holes. Conductive rods are fixedly connected to both sides of the moving rod. The conductive rods are slidably connected with the corresponding second conductive blocks. The two conductive rods are electrically connected to the permanent magnet in series through a conductive mechanism.

[0014] Preferably, the conductive mechanism includes two sliding contact rods fixedly connected to one side of the displacement disc. Two first sliding contact blocks are fixedly connected to both sides of the sliding rod corresponding to the moving rod.

The support seat, the displacement disc, and the gear disc are provided with avoidance through grooves with a diameter larger than the outer diameter of the ship's long pipe.

[0017] A production method of a ship pipe fitting processing and production device includes the following steps:

[0018] S1: The feeding mechanism conveys the pipes stored in the warehouse to the logistics roller path to complete feeding.

[0020] S3: The short pipe processing equipment welds the short pipe and the flange, and the long pipe welding equipment welds the long pipe and the flange.

[0021] S4: The welded long pipe and short pipe are transported by the AGV carrier to the pipe bender for bending, completing the automatic welding of the bent pipe and the flange.

[0022] The present invention has the following beneficial effects:

[0023] 1. In the present invention, the moving seat drives the support disk to move to the outside of the ship's long pipe to be welded. The second motor drives the gear disk to rotate, so that the contact rod contacts the ship's long pipe driven by the corresponding sliding rod, and the moving rod drives the positioning rod to move to the position corresponding to the circumferential position of the bolt holes on the flange corresponding to the ship's long pipe. During the process that the manipulator cooperates with the clamping mechanism to clamp and drive the flange horizontally to the ship's long pipe, the first motor drives the displacement disk to rotate. Cooperating with the moving rod to drive the positioning rod, under the pushing action of the inner spring, the positioning rod contacts the side of the flange and moves circumferentially around the axis of the flange relative to the flange until the positioning rod extends into the bolt hole and continues to move to drive the flange to rotate to a rated angle, completing the angle calibration and positioning of the flange hole, ensuring the welding quality of the flange and the pipe, improving the welding efficiency of the automatic welding equipment, and when welding large-sized pipe fittings, in the case of existing weld points, the positioning rod rotates to drive the entire flange and pipe to rotate, facilitating the addition of weld points and improving the stability of the preliminary welding fixation.

[0024] 2. In the present invention, the first through groove and the second through groove cooperate with the sliding rod to drive the corresponding contact rod and moving rod to move different distances respectively. When welding pipes of different specifications, after the contact rod extends a corresponding length, the length that the moving rod extends is always adapted to the distance from the corresponding bolt hole of the flange of the adapted pipe to the axis, and in cooperation with the misaligned expansion and contraction of the sleeve and the positioning rod, when contacting flanges of different specifications, the clamping mechanism can be locked by the friction between the friction plate and the rotating shaft before the positioning rod extends into the bolt hole, and the restriction on the rotation of the flange is removed when the positioning rod drives the flange to rotate, ensuring the accuracy and reliability of the flange angle calibration. By calibrating the flange and preliminarily welding and fixing the pipe, it enables subsequent external welding or internal welding of the flanges on both sides of the ship's long pipe at the same welding station when clamping the flange by a single hollow displacement device, improving the processing efficiency of ship pipe fittings.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment 1

[0039] Please refer toFigures 1-5 , Figure 7 and Figure 8 , a ship pipe fitting processing and production device, including a moving seat 1 and a bin 3. Both the bin 3 and the moving seat 1 are provided in two, for welding both sides of the long pipe simultaneously. On one side of the top of the bin 3, a long pipe welding robot 4 for welding the ship long pipe 13 and the flange 9 is fixedly arranged. On one side of the top of the moving seat 1, a robotic arm 5 for clamping the flange 9 is fixedly connected. One end of the robotic arm 5 is fixedly connected with a fixed seat 7. On one side inside the fixed seat 7, a rotating shaft 15 is rotatably clamped. On one side of the rotating shaft 15, a clamping mechanism 8 for clamping the flange 9 is fixedly connected. The clamping mechanism 8 can clamp the side of the flange 9. The robotic arm 5 can drive the fixed seat 7 to move, the fixed seat 7 drives the rotating shaft 15 to move, and then drives the clamping mechanism 8 to move, and sleeving the flange 9 clamped by the clamping mechanism 8 perpendicularly to the outside of the flange 9 driven by the flange 9.

[0040] An identification mechanism for identifying the model of the flange 9 is arranged on the robotic arm 5, and the corresponding model of the flange 9 is grabbed when welding ship long pipes 13 of different specifications. On one side of the top of the moving seat 1, a support seat 2 is fixedly connected. On one side near the top of the support seat 2, a displacement gear ring 22 is rotatably connected through a bearing. The displacement gear ring 22 is an external gear ring. On one side of the displacement gear ring 22, a rotating ring 23 is fixedly connected. An outer side of the rotating ring 23 is fixedly sleeved with a displacement disc 10. On one side near the top of the support seat 2, a displacement gear 21 is rotatably connected through a bearing. The displacement gear 21 meshes with the displacement gear ring 22. On one side of the support seat 2, a first motor 20 for driving the displacement gear 21 to rotate is fixedly connected. An output end of the first motor 20 is in transmission connection with the displacement gear 21 through a transmission shaft.

[0041] The rotation of the first motor 20 drives the rotation of the displacement gear 21. The rotation of the displacement gear 21 drives the rotation of the displacement gear ring 22. The displacement gear ring 22 cooperates with the rotating ring 23 to drive the displacement disc 10 to rotate. A sliding groove 37 is opened at the bottom of the displacement disc 10. The sliding groove 37 is a straight groove. A sliding rod 24 is slidably sleeved inside the sliding groove 37. The sliding rod 24 is T-shaped and the wide side is located outside the sliding groove 37, so that the sliding rod 24 can slide along the sliding groove 37 without disengaging from the sliding groove 37. On one side of the sliding rod 24, a moving rod 14 is fixedly connected. The moving rod 14 is L-shaped and a positioning rod 26 is slidably sleeved inside the horizontal part on one side. On one side of the positioning rod 26, an inner spring 30 is fixedly connected. One end of the inner spring 30 is fixedly connected with the moving rod 14. The inner spring 30 pushes the positioning rod 26 to make the positioning rod 26 extend out of the moving rod 14. A telescopic mechanism is arranged on one side of the displacement disc 10. The telescopic mechanism is used to drive the sliding rod 24 to slide in the sliding groove 37.

[0042] When the initial welding of the long ship pipe 13 is carried out, the handling mechanism 6 transports the long ship pipe 13 from the buffer area to between the two robotic arms 5. A traveling mechanism for horizontal movement is provided on the moving seat 1. The support seat 2 and the indexing plate 10 are provided with avoidance through grooves having a diameter larger than the outer diameter of the long ship pipe 13. The movement of the moving seat 1 drives the support seat 2 to move to the outside of the body of the long ship pipe 13 according to the pipe length of the long ship pipe 13. The long pipe robotic arm 5 cooperates with the clamping mechanism 8 to clamp and extract the flange 9 from the magazine 3. At this time, the telescopic mechanism drives the sliding rod 24 to move, and the sliding rod 24 drives the moving rod 14 to move. According to the type of the clamped flange 9, the distance from the center line of the positioning rod 26 to the axis of the long ship pipe 13 is made equal to the distance from the bolt holes on the flange 9 to its own axis.

[0043] After the robotic arm 5 drives the flange 9 to move to one side of the long ship pipe 13 so that the axis of the flange 9 is collinear with the axial direction of the long ship pipe 13, it drives the flange 9 to move horizontally. When the bolt holes on both sides of the flange 9 are angularly misaligned, there is a misalignment between the positioning rod 26 and the bolt holes of the flange 9. When the flange 9 moves to contact the positioning rod 26, it pushes the positioning rod 26 to contract into the moving rod 14, and the inner spring 30 is compressed. At this time, the first motor 20 is started to drive the indexing plate 10 to rotate by a rated angle. The indexing plate 10 drives the sliding rod 24 in the sliding groove 37 to rotate, and then drives the positioning rod 26 to rotate around the axis of the long ship pipe 13 to a rated position. The rotation angle of the positioning rod 26 is not less than the rotation angle between two adjacent bolt holes on the flange 9. The positioning rod 26 abuts against the flange 9 and rotates relative to it until the position of the positioning rod 26 corresponds to the bolt hole. The inner spring 30 pushes the positioning rod 26 to be inserted into the bolt hole. The positioning rod 26 continues to rotate and drives the flange 9 to rotate, so that the bolt holes on the flange 9 are rotated to the rated position to complete the positioning of the bolt holes of the flanges 9 on both sides of the long ship pipe 13, realizing the automatic positioning of the bolt holes of the flange 9 and improving the welding quality and welding efficiency.

[0044] The long pipe welding robot 4 performs external welding of a number of weld spots on the long ship pipe 13 and the flange 9 through the space left between the indexing plate 10 and the clamping mechanism 8. The number of weld spots is at least one, which is used to initially fix the flange 9 and the corresponding long ship pipe 13. After the initial welding, the clamping mechanism 8 releases the flange 9, the robotic arm 5 retracts. After the moving seat 1 moves to drive the positioning rod 26 to disengage from the bolt hole, the telescopic mechanism drives the sliding rod 24 to reset, and then the moving seat 1 moves back to its original position. The top of the handling mechanism 6 is a roller support mechanism, and the long ship pipe 13 can rotate around its own axis. The handling mechanism 6 moves the long ship pipe 13 to the full welding station. At this time, only a single hollow positioner can be used to clamp the flange 9, and cooperate with two long pipe welding robots 4 to weld both sides of the long ship pipe 13 at the same time, and external welding and internal welding of the flange 9 and the long ship pipe 13 can be carried out at the full welding station, that is, welding at the joint between both sides of the flange 9 and the long ship pipe 13, improving the convenience of the full welding of the flange 9 and the long ship pipe 13.

[0045] Embodiment 2

[0046] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7 and Figure 8 On the basis of the first embodiment, the telescopic mechanism includes a toothed disc 11, a avoidance groove is provided at the center of the toothed disc 11, and the diameter of the avoidance groove is greater than the outer diameter of the long tube 13 of the ship, the toothed disc 11 is rotatably connected to the displacement disc 10 through a bearing, a transmission gear 12 is rotatably connected to one side of the bottom of the toothed disc 11 through a bearing, the transmission gear 12 and the toothed disc 11 are meshed with each other, a No. 2 motor 28 for driving the transmission gear 12 to rotate is fixedly connected to the bottom of the toothed disc 11, and the output end of the No. 2 motor 28 is transmission-connected to the transmission gear 12 through a transmission shaft, the number of sliding grooves 37 and sliding rods 24 are both set to two, one of the two sliding rods 24 is fixedly connected to the contact rod 25, a No. 2 through groove 36 corresponding to the moving rod 14 is provided on one side of the toothed disc 11, a No. 1 through groove 35 corresponding to the contact rod 25 is provided on one side of the toothed disc 11, the No. 1 through groove 35 and the No. 2 through groove 36 are both bent, and the sliding rods 24 are respectively located on the inner side of the corresponding No. 1 through groove 35 or the No. 2 through groove 36.

[0047] The second motor 28 rotates to drive the transmission gear 12 to rotate, and the transmission gear 12 drives the toothed disc 11 to rotate, so that the inner walls of the first through slot 35 and the second through slot 36 drive the corresponding sliding rod 24 to slide along the sliding slot 37. When the contact rod 25 contacts the outer wall of the ship's long tube 13, the second motor 28 stops rotating. At this time, the distance from the center line of the positioning rod 26 to the axis of the ship's long tube 13 is equal to the distance from the bolt hole on the flange 9 to its own axis. The bending degrees of the first through slot 35 and the second through slot 36 are different, so that the moving distance of the contact rod 25 is different from the moving distance of the moving rod 14. When welding, the moving distance of the moving rod 14 is adapted to the diameter of the ship's long tube 13, and the moving distance of the positioning rod 26 is adapted to the distance from the bolt hole on the flange 9 to the axis of the flange 9, so as to facilitate the calibration welding of the ship's long tube 13 and the flange 9 of different diameters. When welding the flange 9 and the ship's long tube 13 of large specifications, the first motor 20 drives the positioning rod 26 to rotate the rated angle, and drives the flange 9 and the ship's long tube 13 to rotate after at least one fixed point has been welded, so as to facilitate the welding of multiple welding points for fixing on the flange 9 and the ship's long tube 13, and improve the stability of the initial fixing of the flange 9 and the ship's long tube 13.

[0048] Embodiment 3

[0049] See also Figure 1 , Figures 4-10, on the basis of the second embodiment, a friction plate 16 is slidably sleeved inside the fixed seat 7. The friction plate 16 can only move relative to the fixed seat 7 in the axial direction of the rotating shaft 15. The side of the rotating shaft 15 close to the friction plate 16 is a friction surface. An electromagnet 17 is fixedly arranged on one side inside the fixed seat 7. An adjusting spring 19 for providing a frictional thrust to the friction plate 16 is movably sleeved inside the fixed seat 7. A permanent magnet 18 corresponding to the electromagnet 17 is fixedly connected to one side of the friction plate 16. The force between the permanent magnet 18 and the electromagnet 17 is an attractive force and the attractive force is greater than the elastic force of the adjusting spring 19. A sleeve 27 is slidably sleeved outside the positioning rod 26. The diameter of the positioning rod 26 is adapted to the diameter of the bolt hole on the flange 9. One side of the rod body of the positioning rod 26 is conical, which is convenient for the positioning rod 26 to adapt to different specifications of the flange 9. Second conductive blocks 41 are fixedly arranged on both sides of the sleeve 27. A first conductive block 29 is fixedly connected to one side of the positioning rod 26. An outer spring 31 is fixedly connected to one side of the sleeve 27. Both the inner spring 30 and the outer spring 31 are insulating springs.

[0050] The diameter of the sleeve 27 is greater than the diameter of the bolt hole of the flange 9. Conductive rods 40 are fixedly connected to both sides of the moving rod 14. The conductive rods 40 are in sliding connection with the corresponding second conductive blocks 41. When the positioning rod 26 corresponds to the position of the bolt hole, the telescopic state of the sleeve 27 and the positioning rod 26 changes from the positioning rod 26 and the sleeve 27 extending the same length to the length of the positioning rod 26 being greater than that of the sleeve 27. The moving rod 14 drives the first conductive block 29 to move. The first conductive block 29 comes into contact with the second conductive block 41 and is electrically connected, so that the two conductive rods 40 are electrically connected. The two conductive rods 40 are electrically connected to the electromagnet 17 in series. That is, when the two conductive rods 40 are electrically connected, the circuit in which the electromagnet 17 is connected is connected. Specifically, two sliding contact rods 39 are fixedly connected to one side of the displacement plate 10. Two first sliding contact blocks 32 are fixedly connected to both sides of the sliding rod 24 corresponding to the moving rod 14.

[0051] The first sliding contact block 32 is slidably connected to the corresponding sliding contact rod 39. The two first sliding contact blocks 32 are respectively electrically connected to the two conductive rods 40. A fixed block 34 is fixedly connected to the inner side of the variable-position gear ring 22. Two second sliding contact blocks 38 are fixedly connected to one side of the fixed block 34. The two second sliding contact blocks 38 are respectively electrically connected to the two sliding contact rods 39. Two sliding contact rings 33 are fixedly connected to one side of the support base 2. The sliding contact ring 33 is slidably connected to the corresponding second sliding contact block 38. The two sliding contact rings 33 can be electrically connected to the electromagnet 17 in series. When the position of the positioning rod 26 is misaligned with the position of the bolt hole on the flange 9, the adjusting spring 19 pushes the friction plate 16 to abut against the rotating shaft 15, restricting the clamping mechanism 8 from driving the flange 9 to rotate. When the positioning rod 26 extends into the bolt hole, the circuit connected to the electromagnet 17 is connected. The electromagnet 17 cooperates with the permanent magnet 18 to drive the friction plate 16 to disengage from the contact with the rotating shaft 15, removing the restriction on the rotation of the flange 9, avoiding the positioning rod 26 driving the flange 9 to rotate when contacting the side of different specifications of the flange 9, ensuring that the positioning rod 26 can rotate relative to the flange 9 to correspond to the bolt hole, and improving the reliability of the use of the device.

[0052] Refer to Figures 1-11 , a production method of a ship pipe fitting processing and production device, including the following steps:

[0053] S1: The feeding mechanism transports the pipe storage rack stored in the warehouse to the logistics roller path to complete feeding. The logistics roller path transports the pipe to the lower part of the laser cutting equipment. The laser cutting equipment performs actions such as cutting, beveling, opening intersecting holes, and drawing positioning lines according to the requirements of the ship pipe system;

[0054] S2: The coding device numbers the cut pipes for subsequent traceability. The material roller path transports the cut pipes to the discharging mechanism. The discharging mechanism transports the long and short materials to the buffer areas of the short pipe welding area and the long pipe welding area respectively according to the length of the pipes;

[0055] S3: The handling mechanism 6 moves the pipes in the buffer area to the corresponding welding equipment. The short pipe welding robot clamps the flange 9 from the material bin 3 and places it on the variable-position mechanism at the preliminary welding station, and clamps the short pipe vertically and places it inside the flange 9. The welding device performs preliminary spot welding on the joint between the short pipe and the flange 9, fixing the flange 9 and the short pipe with several welded points. After preliminary welding, the short pipe welding robot clamps the short pipe and the flange 9 and moves them to the variable-position mechanism at the full welding station to perform full welding on the flange 9 and the short pipe;

[0056] S4: When welding the long pipe, the moving seat 1 moves to both sides of the ship's long pipe 13. Both robotic arms 5 cooperate with the clamping mechanism 8 to pick up the flanges 9 from the bin 3, and sleeve the two flanges 9 vertically onto the outside of the ship's long pipe 13. The first motor 20 drives the rotation of the indexing plate 10, and cooperates with the telescopic mechanism to drive the positioning rod 26 to move, so that the positioning rod 26 rotates and extends into the bolt holes of the flange 9 and drives the flange 9 to rotate to a rated angle to calibrate the angle of the flange 9.

[0057] S5: Perform preliminary welding on several points at the joint of the flange 9 and the ship's long pipe 13. After welding and fixing, the clamping mechanism 8 releases the flange 9, the robotic arm 5 retracts, and after the moving seat 1 moves to disengage the positioning rod 26 from the bolt hole, the telescopic mechanism drives the positioning rod 26 to reset, and then the moving seat 1 moves back to its original position.

[0058] S6: Use two long-pipe welding robots 4 to simultaneously perform preliminary welding on the flanges 9 on both sides. After preliminary welding, the handling mechanism 6 moves the ship's long pipe 13 and the flange 9 to the full-welding station, and cooperates with a single hollow indexing device to clamp the flange 9, and simultaneously perform internal welding or external welding on the flanges 9 on both sides of the ship's long pipe 13.

[0059] S7: The welded long pipe and short pipe are transported to a pipe bender by an AGV carrier to perform bending, completing the automatic welding of the bent pipe and the flange 9.

[0060] The usage method (working principle) of the present invention is as follows:

[0061] Before full welding of the long pipe, the two moving seats 1 respectively move to both sides of the ship's long pipe 13, so that the body of the ship's long pipe 13 passes through the support seat 2 by a rated distance. The robotic arm 5 drives the clamping mechanism 8 to identify and pick up the flange 9 from the bin 3, and pushes the flange 9 to the body of the ship's long pipe 13. According to the identified model of the flange 9, the telescopic mechanism cooperates with the moving rod 14 to drive the positioning rod 26 to move to the circumference of the bolt holes of the flange 9, facilitating welding of long pipes of different specifications. The first motor 20 cooperates with the indexing gear 21, indexing ring gear 22, and rotating ring 23 to drive the indexing plate 10 to rotate, thereby driving the moving rod 14 to rotate, so that the moving rod 14 drives the positioning rod 26 to contact the flange 9 and rotate relative to the flange 9 until the positioning rod 26 extends into the bolt hole driven by the inner spring 30.

[0062] At this time, the positioning rod 26 moves relative to the sleeve 27, the conductive structure is electrically connected, the circuit in which the electromagnet 17 is connected is connected, and the friction plate 16 is driven by the permanent magnet 18 to disengage from the friction surface of the rotating shaft 15, removing the locking of the rotation of the flange 9, avoiding the rotation of the flange 9 driven by the positioning rod 26 without extending into the bolt hole when contacting flanges 9 of different specifications. The positioning rod 26 rotates and cooperates with the bolt hole to drive the flange 9 to rotate to a rated angle, completing the adjustment and positioning of the angle of the flange 9, improving the welding quality of the automatic welding equipment, ensuring the welding efficiency, and facilitating the subsequent internal welding and external welding on the same full-welding station.
