Description

Technical Field

[0001] This invention relates to corrugated pipe assembly equipment, and more specifically, to a corrugated pipe nut assembly equipment and assembly process. Background Technology

[0002] Metal corrugated pipes are commonly used in pipeline connections due to their high strength and good shaping effect. When assembling corrugated pipes, two nuts are often put on them to connect the two joints in the pipeline. Currently, this is done manually, which is inefficient and has a high defect rate. Therefore, there is an urgent need to improve this method. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a corrugated pipe nut assembly equipment and assembly process. By setting up a rotary cutting machine, a flattening mechanism, a transfer mechanism and a feeding tray, the corrugated pipe and two nuts can be automatically assembled with high efficiency and good consistency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a corrugated pipe nut assembly device, comprising a workbench, a conveyor table, a first flattening device, a transfer mechanism, a feeding tray, a discharging mechanism, and a second flattening device;

[0005] The conveyor is located on the side of the workbench, and a rotary cutter is fixed on the upper part of the conveyor. The rotary cutter is used to cut corrugated pipes.

[0006] The first flattening device is slidably connected to the upper part of the worktable and can reciprocate along the length of the worktable. The second flattening device is fixedly connected to the upper part of the worktable. The first flattening device and the second flattening device are respectively used to flatten the two ends of the corrugated pipe so that the diameter of the two ends of the corrugated pipe is enlarged.

[0007] The feeding tray is located on the side of the workbench, and the discharging mechanism is fixed on the upper part of the workbench and located on the side of the feeding tray. The feeding tray is used to sequentially convey nuts into the discharging mechanism.

[0008] The transfer mechanism is slidably connected to the upper part of the worktable and can reciprocate along the length of the worktable. The transfer mechanism is used to transfer the corrugated pipe cut by the veneer machine to the discharge mechanism and the second flattening device in sequence.

[0009] Furthermore, the worktable includes a rack and a guide rail arranged along its length, the first flattening device includes a first motor, the drive shaft of the first motor meshes with the rack, the first flattening device is slidably connected to the guide rail, the transfer mechanism includes a second motor, the drive shaft of the second motor meshes with the rack, and the transfer mechanism is slidably connected to the guide rail.

[0010] Furthermore, both the first and second flattening devices include a flattening mechanism. The flattening mechanism includes a first support platform, a first cylinder, a second support platform, a second cylinder, and a locking mechanism. The first cylinder is fixed to the first support platform, the second support platform is fixed to the telescopic rod of the first cylinder, and the second cylinder is fixed to the second support platform. The locking mechanism is connected to the telescopic rod of the second cylinder. The second cylinder can drive the locking mechanism to move, so that the locking mechanism clamps the bellows and the end of the telescopic rod of the second cylinder flattens one end of the bellows.

[0011] Furthermore, the locking mechanism includes two sliders, one end of which is connected to a connecting arm. The second cylinder can drive the two connecting arms to move so that the two sliders move closer to each other and clamp the bellows.

[0012] Furthermore, the transfer mechanism includes a third support platform, a fourth support platform, a third cylinder, a second support plate, a fourth cylinder, a third support plate, and a first clamping block. The second motor and the third cylinder are fixed on the third support platform. The telescopic rod of the third cylinder is connected to the fourth support platform. The second support plate is fixed on the upper part of the fourth support platform. The fourth cylinder is fixed on the side of the second support plate. The third support plate is connected to the fourth cylinder. There are two first clamping blocks, each connected to a fifth cylinder. The fifth cylinder can drive the two first clamping blocks to move closer or further apart.

[0013] Furthermore, the feeding tray includes a feeding track, and the nuts are vertically arranged and distributed within the feeding track. The discharging mechanism includes two opposing sixth cylinders. The end of the telescopic rod of the sixth cylinder is fixed with a second clamping block. The second clamping block is located below the outlet end of the feeding track. The two second clamping blocks can abut against each other or move away from each other. When the two second clamping blocks abut against each other, a V-shaped groove is formed, and the lowest nut is located within the V-shaped groove.

[0014] Furthermore, the discharge mechanism also includes a fourth support plate fixed to the worktable. A seventh cylinder and an eighth cylinder are fixed to the side of the fourth support plate respectively. A partition is fixed to the end of the telescopic rod of the seventh cylinder. The partition is movable so that it can be inserted between two adjacent nuts or detached from the nuts. A positioning rod is fixed to the end of the telescopic rod of the eighth cylinder. The positioning rod is movable so that it can pass through the nut or detach from the nut. The positioning rod is located above the partition.

[0015] Furthermore, the discharge mechanism also includes a fifth support platform, a rotary cylinder, and a sixth support platform. The fifth support platform is fixed to the upper part of the worktable, the rotary cylinder is fixed to the upper part of the fifth support platform, and the sixth support platform is located above the rotary cylinder and is rotatably connected to the rotary cylinder. The two sixth cylinders are respectively fixed on both sides of the sixth support platform.

[0016] A bellows nut assembly process includes the following steps:

[0017] S1. Load the corrugated pipe roll to be cut into the material tray frame. After the corrugated pipe passes through the conveyor table, its end passes through the rotary cutter.

[0018] S2. The first flattening device moves to the front end of the veneer cutter, and the first cylinder of the first flattening device pushes the locking mechanism to move toward the end of the corrugated pipe until the end of the corrugated pipe is inserted into the locking mechanism.

[0019] S3. After the second cylinder works and drives the locking mechanism to clamp the bellows, its telescopic rod squeezes the end of the bellows so that the end of the bellows is flattened and the size of the flattened part is larger than the diameter of the bellows.

[0020] S4. The first flattening device is reset;

[0021] S5. The transfer mechanism moves to the front end of the veneer cutting machine, and the conveyor conveys the corrugated pipe to the transfer mechanism. The corrugated pipe passes through the two first clamping blocks of the transfer mechanism and is clamped by the first clamping blocks.

[0022] S6. The rotary cutter cuts the corrugated pipe.

[0023] S7. The transfer mechanism transfers the cut corrugated pipe to the front of the discharge mechanism so that the corrugated pipe is facing a nut.

[0024] S8. The transfer mechanism drives the bellows to move toward the discharge mechanism so that the bellows passes through the nuts. This is repeated twice so that two nuts are fitted on the bellows.

[0025] S9. The transfer mechanism drives the bellows with two nuts on it to move to the front of the second flattening device;

[0026] S10. The transfer mechanism drives the bellows to move toward the second flattening device so that the unflattened end of the bellows is inserted into the locking mechanism of the second flattening device and flattened by the second flattening device.

[0027] S11. Complete the assembly of the bellows nut.

[0028] Furthermore, step S8 includes installing two nuts of the same size and two nuts of different sizes;

[0029] Installing two identical nuts involves the following steps:

[0030] After the bellows passes through a nut, the transfer mechanism drives the bellows to retract, and the nut located above descends;

[0031] The transfer mechanism once again moves the bellows toward the discharge mechanism, so that another nut is fitted onto the bellows;

[0032] Installing two nuts of different sizes involves the following steps:

[0033] After the first nut is fitted onto the bellows, the transfer mechanism moves the bellows to the front of another discharge mechanism and then fits the nut from the other discharge mechanism onto the bellows.

[0034] In summary, the present invention has the following beneficial effects:

[0035] 1. The movement of the extrusion table driven by the second cylinder can first drive the locking mechanism to move and clamp the bellows, and then extrude the end of the bellows to flatten it. It is easy to operate, efficient and reliable.

[0036] 2. In this embodiment, by setting up a rotary cutting machine, a flattening mechanism, a transfer mechanism, a feeding tray, and a discharge mechanism, the corrugated pipe and the two nuts can be automatically assembled, which is highly efficient and consistent. Attached Figure Description

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] like Figures 1 to 10 As shown, this embodiment discloses a corrugated pipe nut assembly equipment, including a workbench 1, a conveyor 2, a first flattening device, a transfer mechanism 4, a feeding tray 5, a discharging mechanism 6, and a second flattening device.

[0050] The conveyor 2 is located on the side of the workbench 1. A rotary cutter 21 is fixed on the upper part of the conveyor 2. The feeding tray 5 is located on the side of the workbench 1. In this invention, the conveyor 2 is used to convey the corrugated pipe roll material, thereby realizing the feeding of the corrugated pipe 8. The rotary cutter 21 is used to cut the corrugated pipe 8. The feeding tray 5 is used to convey the nuts 9. The feeding tray 5 includes a feeding track 51. The nuts 9 are arranged vertically in the feeding track 51. The conveyor 2, the rotary cutter 21 and the feeding tray 5 are all existing technologies, and their specific structures will not be described in detail in this specification.

[0051] like Figure 1 , Figure 4 and Figure 5As shown, the worktable 1 includes a rack 11 and a guide rail 12 arranged along its length. Specifically, the first flattening device is slidably connected to the upper part of the worktable 1 and can reciprocate along the length of the worktable 1. The transfer mechanism 4 is slidably connected to the upper part of the worktable 1 and can reciprocate along the length of the worktable 1. The first flattening device includes a first motor 39, the drive shaft of the first motor 39 meshes with the rack 11, and the first flattening device is slidably connected to the guide rail 12. The transfer mechanism 4 includes a second motor 49, the drive shaft of the second motor 49 meshes with the rack 11, and the transfer mechanism 4 is slidably connected to the guide rail 12.

[0052] like Figure 1 As shown, the first flattening device is always located on the left side of the transfer mechanism 4. In the initial state, the transfer mechanism 4 is located on the right side of the conveyor 2 and the first flattening device is located on the left side of the conveyor 2. The first motor 39 can drive the first flattening device to move along the guide rail 12, and the second motor 49 can drive the transfer mechanism 4 to move along the guide rail 12. The way the first motor 39 drives the first flattening device to move and the way the second motor 49 drives the transfer mechanism 4 to move are both existing technologies, and their specific cooperation structure will not be described in detail in this specification.

[0053] like Figure 1 , Figures 5 to 8 As shown, the second flattening device is fixedly connected to the upper part of the workbench 1. The first flattening device and the second flattening device are respectively used to flatten the two ends of the corrugated pipe 8 so as to expand the diameter of the two ends of the corrugated pipe 8.

[0054] like Figure 5 As shown, both the first and second flattening devices include a flattening mechanism 3. The flattening mechanism 3 includes a first support platform 31, a first cylinder 32, a second support platform 33, a first support plate 34, two upper and lower fixed plates 35, a second cylinder 37, and a locking mechanism 7. The first cylinder 32 is fixed to the first support platform 31, the second support platform 33 is fixed to the telescopic rod of the first cylinder 32, the second cylinder 37 is fixed to the second support platform 33, the first support plate 34 is fixed to the second support platform 33, the fixed plate 35 is fixed to the first support plate 34, the two fixed plates 35 are fixedly connected by a connecting rod 36, the locking mechanism 7 is located between the two fixed plates 35, the telescopic rod of the second cylinder 37 passes between the two fixed plates 35, and the locking mechanism 7 is connected to the telescopic rod of the second cylinder 37.

[0055] The first support platform 31 located at the lower part of the first flattening device is slidably connected to the guide rail 12, the first motor 39 is fixed on the upper part of the first support platform 31, and the first support platform 31 located at the lower part of the second flattening device is fixedly connected to the upper part of the worktable 1.

[0056] The first cylinder 32 is used to drive the locking mechanism 7 to move horizontally, so that the end of the bellows 8 can be inserted into or detached from the locking mechanism 7. The second cylinder 37 can drive the locking mechanism 7 to move, so that the locking mechanism 7 clamps the bellows 8 and the end of the telescopic rod of the second cylinder 37 flattens one end of the bellows 8.

[0057] like Figures 5 to 7 As shown, the locking mechanism 7 includes two sliders 71, one end of which is connected to a connecting arm 73. The second cylinder 37 can drive the two connecting arms 73 to move, so that the two sliders 71 move closer to each other and clamp the bellows 8. Specifically, the locking mechanism 7 includes a rotating shaft 74 corresponding to the connecting arm 73. The two ends of the rotating shaft 74 are respectively fixed to two fixed plates 35. The rotating shaft 74 is hinged to the connecting arm 73. The end of the telescopic rod of the second cylinder 37 is fixed with a pressing table 38. The pressing table 38 is located between the two connecting arms 73. The pressing table 38 can push the connecting arm 73 to rotate along the rotating shaft 74, so that the two sliders 71 move closer to each other. The connecting arm 73 includes a first movable section 731 and a second movable section 732 located on both sides of the rotating shaft 74. The first movable section 731 can abut against or disengage from the side of the extrusion table 38. The slider 71 has a mounting groove 712 on its side. The end of the second movable section 732 is inserted into the mounting groove 712. One end of the slider 71 is fixed with a clamping piece 711. The clamping pieces 711 of the two sliders 71 can approach each other and be embedded in the corrugated groove of the bellows 8. The extrusion table 38 includes a connecting section 381 and a tapered section 382. The connecting section 381 is fixed to the drive shaft of the second cylinder 37. The first movable section 731 can abut against the side of the tapered section 382 or the side of the connecting section 381.

[0058] like Figure 5 and 6 As shown, when it is necessary to clamp the bellows 8, the first cylinder 32 pushes the locking mechanism 7 and the second cylinder 37 to move towards the end of the bellows 8 until the end of the bellows 8 is inserted between the two sliders 71. The distance of insertion into the sliders 71 is preferably the distance of three bellows segments. Then, the second cylinder 37 pushes the extrusion table 38 to move towards the end of the bellows 8, moving the first movable section 731 from the surface of the conical section 382 to the surface of the connecting section 382. During the movement, the first movable section 731 will expand outward along the surface of the conical section 382, ​​thereby driving the two sliders 71 to move closer to each other. When the two sliders 71 move closer, the two clamping pieces 711 will also move closer to each other and clamp the bellows 8. At this time, the extrusion table 38 has not yet contacted the end of the bellows 8. Afterward, the extrusion table 38 continues to move, and the end of the extrusion table 38 abuts against and extrudes the end of the bellows 8, thereby flattening the end of the bellows 8. The flattened size is larger than the diameter of the bellows 8.

[0059] The second cylinder 37 drives the extrusion table 38 to move, which first drives the locking mechanism 7 to move and clamp the bellows 8, and then extrudes the end of the bellows 8 to flatten it. The operation is convenient, efficient and reliable.

[0060] like Figure 6 river Figure 7 As shown, the slider 71 includes a protrusion 713 located between two fixing plates 35. Each fixing plate 35 includes a guide hole 351 corresponding to the slider 71. The cross-section of the protrusion 713 is larger than that of the guide hole 351. Both ends of the slider 71 pass through the guide holes 351 of the two fixing plates 35. Springs 72 are provided on the outside of both fixing plates 35. The springs 72 are located between the two sliders 71. The two ends of the springs 72 abut against the opposite sides of the two sliders 71. The springs 72 have an outward expansion force on the two sliders 71. When the end of the bellows 8 is flattened, the pressing table 38 retracts. At this time, the two sliders 71 move away from each other due to the force of the springs 72, which facilitates the removal of the bellows 8.

[0061] like Figure 4 and Figure 9 As shown, the transfer mechanism 4 is used to sequentially transfer the corrugated pipe 8 cut by the rotary cutter 21 to the discharge mechanism 6 and the second flattening device. The transfer mechanism 4 includes a third support platform 41, a fourth support platform 42, a third cylinder 43, a second support plate 44, a fourth cylinder 45, a third support plate 46, and a first clamping block 47. The second motor 49 and the third cylinder 43 are fixed on the third support platform 41. The telescopic rod of the third cylinder 43 is connected to the fourth support platform 42. The second support plate 44 is fixed on the upper part of the fourth support platform 42. The fourth cylinder 45 is fixed on the side of the second support plate 44. The third support plate 46 is connected to the fourth cylinder 45. There are two first clamping blocks 47, each of which is connected to a fifth cylinder 48. The fifth cylinder 48 can drive the two first clamping blocks 47 to move closer or further apart from each other.

[0062] After the first flattening device flattens the end of the corrugated pipe 8 located at the veneer 21, the transfer mechanism 4 moves to the front of the veneer 21 via the second motor 49, so that the corrugated pipe 8 is positioned between the two first clamping blocks 47. Then the conveyor 2 conveys the corrugated pipe 8 so that the flattened end of the corrugated pipe 8 passes between the two first clamping blocks 47. After reaching the set length, the conveyor 2 stops conveying, and the fifth cylinder 48 drives the two first clamping blocks 47 to move closer to each other and clamp the corrugated pipe 8. Then the veneer 21 cuts the corrugated pipe 8. After cutting, the third cylinder 43 drives the second support plate 44 away from the veneer 21, so that the cut corrugated pipe 8 is removed from the veneer 21. Finally, the second motor 49 drives the transfer mechanism 4 to move again, and the transfer mechanism 4 drives the cut corrugated pipe 8 to the discharge mechanism 6.

[0063] like Figure 2 , Figure 3 and Figure 10 As shown, the discharge mechanism 6 is fixed on the upper part of the workbench 1 and located on the side of the feeding tray 5. The feeding tray 5 is used to sequentially transfer the nuts 9 into the discharge mechanism 6.

[0064] The discharge mechanism 6 includes two opposing sixth cylinders 64, a fifth support platform 61, a rotary cylinder 62, and a sixth support platform 63. The fifth support platform 61 is fixed to the upper part of the worktable 1. The rotary cylinder 62 is fixed to the upper part of the fifth support platform 61. The sixth support platform 63 is located above the rotary cylinder 62 and is rotatably connected to the rotary cylinder 62. The two sixth cylinders 64 are respectively fixed on both sides of the sixth support platform 63. A second clamping block 641 is fixed to the end of the telescopic rod of the sixth cylinder 64. The second clamping block 641 is located below the outlet end of the feeding track 51. The two second clamping blocks 641 can abut against each other or move away from each other. When the two second clamping blocks 641 abut against each other, a V-groove 642 is formed. The bottom nut 9 is located in the V-groove 642.

[0065] When the transfer mechanism 4 moves the cut corrugated pipe 8 to the discharge mechanism 6, one end of the corrugated pipe 8 is directly opposite the nut 9 in the V-groove 642. Then, the third cylinder 43 moves the corrugated pipe 8 toward the V-groove 642, and the corrugated pipe 8 passes through the nut 9 inside. Then, the sixth cylinder 64 moves the two second clamping blocks 641 away, and the nut 9 is separated from the second clamping blocks 641. At this time, the third cylinder 43 moves the corrugated pipe 8 back to its original position, and the corrugated pipe 8 and the nut 9 sleeved on the corrugated pipe 8 move away from the discharge mechanism 6.

[0066] like Figure 3 and Figure 10As shown, the discharge mechanism 6 also includes a fourth support plate 65 fixed to the workbench 1. A support frame 13 is fixed to the upper part of the workbench 1, and the fourth support plate 65 is fixed to the support frame 13. A seventh cylinder 66 and an eighth cylinder 67 are respectively fixed to the side of the fourth support plate 65. A partition plate 661 is fixed to the end of the telescopic rod of the seventh cylinder 66. The partition plate 661 is movable so that it can be inserted between two adjacent nuts 9 or detached from the nuts 9. A positioning rod 671 is fixed to the end of the telescopic rod of the eighth cylinder 67. The positioning rod 671 is movable so that it can pass through the nuts 9 or detach from the nuts 9. The positioning rod 671 is located above the partition plate 661. The partition plate 661 is inserted between the nuts 9 located in the V-groove 641 and the nuts 9 located at the top, which can prevent the nuts 9 in the V-groove 641 from being fitted onto the bellows 8. During the process, the nut 9 falls off. After the bellows 8 and the nut 9 are fitted, the second clamping block 641 resets. At this time, the seventh cylinder 66 drives the partition 661 to move. The partition 661 disengages from the nut 9, and the nut 9 above the partition 661 falls into the V-groove 641. Finally, the partition 661 resets and is inserted between the nut 9 in the V-groove 641 and the nut 9 at the top. The positioning rod 671 moves synchronously with the partition 661. That is, when the partition 661 disengages from the nut 9, the positioning rod 671 also disengages from the corresponding nut 9. There is a nut 9 between the positioning rod 671 and the partition 661. By setting the positioning rod 671, the distance between the positioning rod 671 and the V-groove 641 can be ensured, thereby greatly improving the positional accuracy of the nut 9 between the two and ensuring that the bellows 8 can smoothly pass through the nut 9 in the V-groove 641.

[0067] After the transfer mechanism 4 and the discharge mechanism 6 perform two nut 9 fitting operations, the transfer mechanism 4 drives the bellows 8 with two nuts 9 fitted to move to the second flattening device. The second flattening device flattens the other end of the bellows 8. The way the second flattening device flattens the end of the bellows 8 is the same as that of the first flattening device. Therefore, its specific operation method will not be described in detail in this specification. After the two ends of the bellows 8 are flattened, the assembly of the bellows 8 and the nuts 9 is completed.

[0068] In this embodiment, by setting up a rotary cutting machine 21, a flattening mechanism 3, a transfer mechanism 4, a feeding tray 5, and a discharging mechanism 6, the corrugated pipe 8 and the two nuts 9 can be automatically assembled with high efficiency and good consistency.

[0069] A bellows nut assembly process includes the following steps:

[0070] S1. Load the corrugated pipe 8 roll into the material tray frame. After the corrugated pipe 8 passes through the conveyor table 2, its end passes through the rotary cutter 21.

[0071] S2. The first flattening device moves to the front end of the veneer cutter 21. The first cylinder 32 of the first flattening device pushes the locking mechanism 7 toward the end of the corrugated pipe 8 until the end of the corrugated pipe 8 is inserted into the locking mechanism 7.

[0072] S3. After the second cylinder 37 works and drives the locking mechanism 7 to clamp the bellows 8, its telescopic rod squeezes the end of the bellows 8 so that the end of the bellows 8 is flattened and the size of the flattened part is larger than the diameter of the bellows 8.

[0073] S4. The first flattening device is reset;

[0074] S5. The transfer mechanism 4 moves to the front end of the veneer cutter 21. The conveyor 2 conveys the corrugated tube 8 to the transfer mechanism 4. The corrugated tube 8 passes through the two first clamping blocks 47 of the transfer mechanism 4 and is clamped by the first clamping blocks 47.

[0075] S6, the rotary cutting machine 21 cuts the corrugated pipe 8;

[0076] S7. The transfer mechanism 4 transfers the cut corrugated pipe 8 to the front of the discharge mechanism 6 so that the corrugated pipe 8 is facing a nut 9.

[0077] S8. The transfer mechanism 4 drives the bellows 8 to move toward the discharge mechanism 6 so that the bellows 8 passes through the nuts 9. This is repeated twice so that two nuts 9 are fitted on the bellows 8.

[0078] Step S8 includes installing two nuts 9 of the same size and two nuts 9 of different sizes;

[0079] Installing two identical nuts involves the following steps:

[0080] After the bellows 8 passes through a nut 9, the transfer mechanism 4 drives the bellows 8 to retract, and the nut 9 located above descends;

[0081] The transfer mechanism 4 drives the bellows 8 to move toward the discharge mechanism 6 again, so that another nut 9 is fitted onto the bellows 8;

[0082] Installing two nuts of different sizes involves the following steps:

[0083] After the first nut 9 is fitted onto the bellows 8, the transfer mechanism 4 moves the bellows 8 to the front of another discharge mechanism 6 and fits the nut 9 on the other discharge mechanism 6 onto the bellows 8.

[0084] When installing nuts 9 of the same specification, only one feeding tray 5 and one discharging mechanism 6 are needed; if nuts 9 of different specifications are installed, two feeding trays 5 and two discharging mechanisms 6 are needed.

[0085] S9, the transfer mechanism 4 drives the bellows 8, which is fitted with two nuts 9, to move to the front of the second flattening device;

[0086] S10, the transfer mechanism 4 drives the bellows 8 to move toward the second flattening device, so that the unflattened end of the bellows 8 is inserted into the locking mechanism 7 of the second flattening device and flattened by the second flattening device;

[0087] S11. Complete the assembly of bellows 8 and nut 9.
