Description

Technical Field

[0001] The present invention relates to the technical field of ship piping manufacturing and processing equipment, in particular to ship pipe processing and production equipment and a production method thereof. Background Art

[0002] The production of ship piping is an important part of the shipbuilding process and one of the important factors affecting the progress of shipbuilding. Existing ship piping processing equipment usually adopts the production process of "bending first and then welding", using cutting equipment to cut the pipe according to the design requirements, separating the cut pipes through a separation mechanism, and moving the pipes to the pipe bending machine through handling equipment, first bending the pipes on the pipe bending machine, then calibrating and positioning the pipes and flanges on the manual pipe calibration platform, and then manually welding.

[0003] However, when traditional ship piping processing equipment determines the cutting length of the straight pipe section, due to the error and rebound during bending, the cutting length usually needs to have a certain process margin. The pipe needs to be cut twice during assembly, which wastes raw materials and reduces production efficiency. After bending, the pipe is difficult to assemble on the pipe calibration machine. The flange needs to be manually assembled on the bent pipe, and the relative angles of the flange holes on both sides of the pipe need to be manually calibrated to ensure that the flanges on both sides of the bent pipe will not be misaligned after welding, so that the flanges can be connected smoothly during pipeline assembly to avoid connection difficulties or poor sealing due to misaligned bolt holes. Flange welding also needs to be performed on the bent pipe. The bending of the pipe and the calibration of the flange make it difficult to use an automatic flange welding machine to weld the pipe to the flange, resulting in low efficiency in pipe calibration and welding, and quality cannot be guaranteed.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1

[0039] See also Figure 1-Figure 5 , Figure 7 and Figure 8 A ship pipe processing and production equipment comprises a movable seat 1 and a silo 3. The silo 3 and the movable seat 1 are both set as two and are used to weld both sides of a long pipe at the same time. A long pipe welding robot 4 for welding a ship long pipe 13 and a flange 9 is fixedly arranged on one side of the top of the silo 3. A mechanical arm 5 for clamping the flange 9 is fixedly connected to one side of the top of the movable seat 1. One end of the mechanical arm 5 is fixedly connected to a fixed seat 7. A rotating shaft 15 is rotatably clamped on one side of the inside of the fixed seat 7. A clamping mechanism 8 for clamping the flange 9 is fixedly connected to one side of the rotating shaft 15. The clamping mechanism 8 can clamp the side of the flange 9. The mechanical arm 5 can drive the fixed seat 7 to move, and the fixed seat 7 drives the rotating shaft 15 to move, thereby driving the clamping mechanism 8 to move, and the flange 9 clamped by the clamping mechanism 8 is driven to be sleeved to the outside of the flange 9 perpendicular to the flange 9.

[0040] The mechanical arm 5 is provided with an identification mechanism for identifying the model of the flange 9, and the flange 9 of the corresponding model can be grasped when welding long ship pipes 13 of different specifications. One side of the top of the movable seat 1 is fixedly connected to the support seat 2, and the side of the support seat 2 close to the top is rotatably connected to the displacement gear ring 22 through a bearing. The displacement gear ring 22 is an outer gear ring, and one side of the displacement gear ring 22 is fixedly connected to a rotating ring 23, and the outer side of the rotating ring 23 is fixedly sleeved with a displacement disk 10. The side of the support seat 2 close to the top is rotatably connected to the displacement gear 21 through a bearing, and the displacement gear 21 and the displacement gear ring 22 are meshed with each other. One side of the support seat 2 is fixedly connected to a No. 1 motor 20 for driving the displacement gear 21 to rotate, and the output end of the No. 1 motor 20 is transmission-connected to the displacement gear 21 through a transmission shaft.

[0041] The rotation of motor No. 1 20 drives the shift gear 21 to rotate, and the rotation of the shift gear 21 drives the shift gear ring 22 to rotate. The shift gear ring 22 cooperates with the rotating ring 23 to drive the shift disk 10 to rotate. A sliding groove 37 is provided at the bottom of the shift disk 10. The sliding groove 37 is a straight groove. A sliding rod 24 is slidably sleeved on the inner side of the sliding groove 37. The sliding rod 24 is T-shaped and the wide side is located on the outer side of the sliding groove 37, so that the sliding rod 24 can slide along the sliding groove 37 without leaving the sliding groove 37. A moving rod 14 is fixedly connected to one side of the sliding rod 24. The moving rod 14 is L-shaped and a positioning rod 26 is slidably sleeved on one side of the horizontal part. An inner spring 30 is fixedly connected to one side of the positioning rod 26. One end of the inner spring 30 is fixedly connected to 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 provided on one side of the shift disk 10. The telescopic mechanism is used to drive the sliding rod 24 to slide in the sliding groove 37.

[0042] When the long tube 13 of the ship is initially welded, the transport mechanism 6 transports the long tube 13 of the ship from the buffer area to between the two mechanical arms 5. The moving seat 1 is provided with a walking mechanism for horizontal movement. The support seat 2 and the displacement plate 10 are provided with avoidance grooves with a diameter larger than the outer diameter of the long tube 13 of the ship. The movement of the moving seat 1 drives the support seat 2 to move to the outside of the tube body of the long tube 13 of the ship according to the tube length of the long tube 13 of the ship. The long tube mechanical arm 5 cooperates with the clamping mechanism 8 to clamp the flange 9 from the silo 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 model of the clamped flange 9, the distance from the center line of the positioning rod 26 to the axis of the long tube 13 of the ship is equal to the distance from the bolt hole on the flange 9 to its own axis.

[0043] The mechanical arm 5 drives the flange 9 to move to one side of the ship's long tube 13 so that the axis of the flange 9 is in line with the axial direction of the ship's long tube 13, and then drives the flange 9 to move horizontally. When the bolt holes on the flange 9 on both sides of the flange 9 are misaligned, the positioning rod 26 is misaligned with 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 retract into the moving rod 14, and the inner spring 30 is compressed. At this time, the No. 1 motor 20 starts to drive the displacement plate 10 to rotate the rated angle, and the displacement plate 10 drives the sliding rod 24 in the sliding groove 37 to rotate, thereby driving the positioning rod 26 to retract into the moving rod 14. The rod 26 rotates around the axis of the ship's long tube 13 to the 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 presses against the flange 9 and rotates relatively until the position of the positioning rod 26 corresponds to the position of the bolt hole. The inner spring 30 pushes the positioning rod 26 to be embedded in 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 rotate to the rated position to complete the bolt hole positioning of the flange 9 on both sides of the ship's long tube 13, realize automatic positioning of the bolt holes of the flange 9, and improve welding quality and welding efficiency.

[0044] The long tube welding robot 4 performs external welding of the ship's long tube 13 and the flange 9 at several welding points through the space left between the displacement plate 10 and the clamping mechanism 8. There is at least one welding point, which is used to preliminarily fix the flange 9 and the corresponding ship's long tube 13. After the preliminary welding, the clamping mechanism 8 releases the flange 9, the mechanical arm 5 is retracted, and 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 and resets. The top of the conveying mechanism 6 is a roller support mechanism, and the ship's long tube 13 can rotate around its own axis. The conveying mechanism 6 moves the ship's long tube 13 to the full welding station. At this time, only a single hollow positioner can be used to clamp the flange 9, and two long tube welding robots 4 can be used to weld both sides of the ship's long tube 13 at the same time, and the external welding and internal welding of the flange 9 and the ship's long tube 13 can be performed at the full welding station, that is, the welding of the joints between the two sides of the flange 9 and the ship's long tube 13, which improves the convenience of full welding of the flange 9 and the ship's long tube 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 , Figure 4-Figure 10On the basis of the second embodiment, the inner side of the fixed seat 7 is slidably sleeved with the friction plate 16, and 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 of the fixed seat 7. An adjusting spring 19 for providing friction thrust to the friction plate 16 is movably sleeved on the inner side of 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 permanent magnet 18 and the electromagnet 17 are connected to each other. The acting force is an attractive force and the attractive force is greater than the elastic force of the adjusting spring 19. The outer side of the positioning rod 26 is slidably sleeved with a sleeve 27. 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 tapered, which is convenient for the positioning rod 26 to adapt to flanges 9 of different specifications. No. 2 conductive blocks 41 are fixedly provided on both sides of the sleeve 27, and No. 1 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. The inner spring 30 and the outer spring 31 are both insulating springs.

[0050] The diameter of the sleeve 27 is larger than the diameter of the bolt hole of the flange 9. Conductive rods 40 are fixedly connected on both sides of the moving rod 14. The conductive rods 40 are slidably connected to the corresponding No. 2 conductive block 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 sleeve 27 and the positioning rod 26 extending the same length to the length of the positioning rod 26 being greater than the sleeve 27. The moving rod 14 drives the No. 1 conductive block 29 to move. The No. 1 conductive block 29 contacts and electrically connects with the No. 2 conductive block 41, 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 connected to the electromagnet 17 is connected. Specifically, one side of the displacement disk 10 is fixedly connected with two sliding contact rods 39, and the two sides of the sliding rod 24 corresponding to the moving rod 14 are fixedly connected with two No. 1 sliding contact blocks 32.

[0051] The first sliding contact block 32 is slidably connected to the corresponding sliding contact rod 39, and the two first sliding contact blocks 32 are electrically connected to the two conductive rods 40 respectively.

The two sliding contact rings 33 can be electrically connected to the electromagnet 17 in a serial manner. When the position of the flange 9 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, limiting 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, and the electromagnet 17 cooperates with the permanent magnet 18 to drive the friction plate 16 to break away from the contact with the rotating shaft 15, removing the restriction on the rotation of the flange 9, avoiding the positioning rod 26 from driving the flange 9 to rotate when it contacts the side of the flange 9 of different specifications, ensuring that the positioning rod 26 can rotate relative to the flange 9 to correspond to the bolt hole, thereby improving the reliability of the equipment.

[0054] S2: The coding device numbers the cut tubes for easy traceability. The material roller conveys the cut tubes to the unloading mechanism. The unloading mechanism conveys the long and short materials to the buffer areas of the short tube welding area and the long tube welding area respectively according to the length of the tubes.

[0055] S3: The transport mechanism 6 moves the pipes in the buffer area to the corresponding welding equipment, the short-tube welding robot clamps the flange 9 from the silo 3 and places it on the displacement mechanism of the preliminary welding station, and clamps the short tube and places it vertically on the inner side of the flange 9, and uses the welding device to perform preliminary spot welding on the joint between the short tube and the flange 9, and fixes the flange 9 and the short tube by several welding points. After preliminary welding, the short-tube welding robot clamps the short tube connecting the flange 9 and moves it to the displacement mechanism of the full welding station, and fully welds the flange 9 and the short tube;

[0056] S4: When welding the long pipe, the moving seat 1 moves to both sides of the ship's long pipe 13, and the two mechanical arms 5 cooperate with the clamping mechanism 8 to clamp the flange 9 from the silo 3, and the two flanges 9 are vertically sleeved on the outside of the ship's long pipe 13. The No. 1 motor 20 drives the displacement plate 10 to rotate, 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 hole of the flange 9 and drives the flange 9 to rotate to the rated angle, and the angle of the flange 9 is calibrated;

[0057] S5: Preliminary welding is performed on several points at the joint of the flange 9 and the long ship tube 13. After the welding is fixed, the clamping mechanism 8 releases the flange 9, the mechanical arm 5 contracts, the moving seat 1 moves to make the positioning rod 26 disengage from the bolt hole, the telescopic mechanism drives the positioning rod 26 to reset, and then the moving seat 1 moves and resets;

[0058] S6: Preliminary welding is performed on the flanges 9 on both sides by two long tube welding robots 4 at the same time. After the preliminary welding, the transport mechanism 6 moves the ship long tube 13 and the flange 9 to the full welding station, cooperates with a single hollow displacement device to clamp the flange 9, and simultaneously performs internal welding or external welding on the flanges 9 on both sides of the ship long tube 13;

[0059] S7: The welded long pipe and short pipe are transported to the pipe bending machine by the AGV transporter for bending, and the automatic welding of the bent pipe and the flange 9 is completed.

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

[0061] Before the long tube is fully welded, the two moving seats 1 are respectively moved to the two sides of the ship's long tube 13, so that the body of the ship's long tube 13 passes through the rated distance of the support seat 2. The mechanical arm 5 drives the clamping mechanism 8 to identify and clamp the flange 9 from the silo 3, and push the flange 9 to the body of the ship's long tube 13. According to the model identified by 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 hole of the flange 9, so as to adapt to the welding of long tubes of different specifications. The No. 1 motor 20 cooperates with the shifting gear 21, the shifting gear ring 22, and the rotating ring 23 to drive the shifting disk 10 to rotate, and then drives 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 is driven by the inner spring 30 extending into the bolt hole.

[0062] At this time, the positioning rod 26 moves relative to the sleeve 27, the conductive structure is electrically connected, the circuit connected to the electromagnet 17 is connected, and the permanent magnet 18 drives the friction plate 16 to disengage from the friction surface of the rotating shaft 15, and the locking of the rotation of the flange 9 is removed to avoid contact with flanges 9 of different specifications so that the positioning rod 26 drives the flange 9 to rotate without extending into the bolt hole. The positioning rod 26 rotates to cooperate with the bolt hole to drive the flange 9 to rotate to the rated angle, completing the adjustment and positioning of the flange 9 angle, improving the welding quality of the automatic welding equipment, ensuring the welding efficiency, and facilitating the subsequent internal welding and external welding at the same full welding station.
