Water distributor fitting and riveting equipment

Abstract

This application relates to a manifold fitting device, including a workbench with a diameter reduction device. The diameter reduction device includes a drive component and two diameter reduction blocks. The two diameter reduction blocks are positioned opposite each other and located on opposite sides of a hollow tube fitted onto the main pipe. The diameter reduction blocks are slidably connected to the workbench along a length perpendicular to the main pipe. The drive component drives the two diameter reduction blocks to move closer or further apart. The opposite sides of the two diameter reduction blocks have a fitting groove matching the standard fitting part of the main pipe fitting. When the two diameter reduction blocks move to abut against each other, the inner diameter of the end of the hollow tube furthest from the hexagonal nut is compressed by the two diameter reduction blocks to a size smaller than the outer diameter of the limiting ring. By driving the two diameter reduction blocks to compress the hollow tube portion of the fitting, the inner diameter of one end of the hollow tube is compressed to the size of the standard part. At this point, the fitting is less likely to separate from the main pipe, thus improving the connection quality between the fitting and the main pipe.

Description

Technical Field

[0001] This application relates to the field of water distributors, and more particularly to a water distributor fitting and riveting device. Background Technology

[0002] A water distributor is a water distribution device in a water system used to connect the supply or return water of various heating pipes.

[0003] Related technologies such as water distributors Figure 1 As shown, the water distributor 1 includes a union joint 12 and a body 11. The body 11 includes a main pipe 111 and multiple branch pipes 112. One end of each branch pipe 112 is connected to the main pipe 111, and the multiple branch pipes 112 are located on the same side of the main pipe 111 and on the same plane. One end of the main pipe 111 is a connecting end 13, and a first limiting ring 131 is coaxially sleeved on the connecting end 13. The first limiting ring 131 is integrally formed with the main pipe 111, and the union joint 12 is movably connected to the connecting end 13. The union joint 12 includes a hexagonal nut 122 and a hollow tube 121. One end of the hollow tube 121 is coaxially fixed to one side of the hexagonal nut 122. The hollow tube 121 and the hexagonal nut 122 are integrally formed. The inner diameter of the hollow tube 121 is equal to the inner diameter of the hexagonal nut 122, and the inner diameter of the hollow tube 121 is larger than the outer diameter of the first limiting ring 131.

[0004] The connection method between the union 12 and the main pipe 111 is as follows: the end of the hollow tube 121 away from the hexagonal nut 122 is aligned with the first limiting ring 131 and inserted. Then, using pliers or other tools, force is applied to the end of the hollow tube 121 away from the hexagonal nut 122, so that the inner diameter of the end of the hollow tube 121 away from the hexagonal nut 122 gradually shrinks to be smaller than the outer diameter of the first limiting ring 131, thereby preventing the union 12 from detaching from the main pipe 111.

[0005] The above-mentioned technical solutions have the following drawbacks: In the connection between the union and the main pipe, the method of using pliers to reduce the inner diameter of the hollow tube end is time-consuming and laborious. At the same time, some hollow tubes are not reduced to the correct diameter, and they will detach from the main pipe with a little force, which cannot guarantee the connection quality between the union and the main pipe. Summary of the Invention

[0006] To improve the connection quality between the union and the main pipe, this application provides a manifold union riveting device.

[0007] The technical solution of the water distributor fitting crimping device provided in this application is as follows:

[0008] A manifold fitting and riveting device includes a workbench with a positioning device and a diameter reduction device. The positioning device is used to fix the main body on the workbench. The diameter reduction device includes a drive component and two diameter reduction blocks. The two diameter reduction blocks are arranged opposite each other and are located on both sides of a hollow tube sleeved on the main pipe. The diameter reduction blocks are slidably connected to the workbench along the length direction perpendicular to the main pipe. The drive component drives the two diameter reduction blocks to move closer to each other or further away from each other. The side of the two diameter reduction blocks facing each other has a fitting groove that matches the standard fitting part of the main pipe fitting. When the two diameter reduction blocks move to abut against each other, the inner diameter of the end of the hollow tube away from the hexagonal nut is squeezed by the two diameter reduction blocks to be smaller than the outer diameter of the first limiting ring.

[0009] By adopting the above technical solution, the positioning device fixes the body on the workbench. Then, the operator puts the union on the connection end of the main pipe. Then, the driving component drives two reducing blocks to squeeze the hollow tube part of the union, so that the inner diameter of one end of the hollow tube is squeezed to the size of the standard part. At this time, the union can be connected to the main pipe and is not easy to separate from the main pipe, which can improve the connection quality between the union and the main pipe.

[0010] Preferably, it also includes a material conveying device and a feeding device. The material conveying device includes a vibratory feeder and a material conveying channel connected at both ends. The workbench is provided with a passageway for the swivel joints to pass through. One end of the material conveying channel is connected to the vibratory feeder, and the other end of the material conveying channel is connected to the passageway. The height of the material conveying channel gradually decreases from the end near the vibratory feeder to the end near the passageway. The vibratory feeder is used to drive the swivel joints to be arranged sequentially and transported into the material conveying channel. The swivel joints in the material conveying channel automatically roll along the material conveying channel into the passageway. The length direction of the passageway is parallel to the length direction of the main pipe and is set directly opposite the connection end of the main pipe. The feeding device is used to move the swivel joints in the passageway to the connection end of the main pipe. When the swivel joint rolls into the passageway, the hollow tube on the swivel joint is located on the side of the hexagonal nut closer to the main pipe.

[0011] By adopting the above technical solution, the vibratory feeder can automatically orient and sort multiple live joints and transport them to the conveying channel. The live joints will move along the conveying channel to the passageway, and then the feeding device will move the live joints in the passageway to the connecting end sleeved on the main pipe, thereby realizing the automatic feeding of live joints on the main pipe.

[0012] Preferably, the material conveying channel is provided with a material dropping device, which includes a first rack, a first gear, a transmission belt, a first cylinder, and a baffle. The first cylinder is fixed on the workbench, and the piston rod of the first cylinder is oriented towards the material conveying channel and can extend into the material conveying channel. The length direction of the piston rod of the first cylinder is parallel to the axis direction of the live interface when it passes through the first cylinder. A first rotating shaft is coaxially fixedly connected to the first gear, and the first rotating shaft is rotatably connected to the material conveying channel. The first rack is fixed to the piston rod of the first cylinder along the length direction parallel to the piston rod of the first cylinder, and the first rack is meshed with the first gear.

[0013] A second rotating shaft is fixed to the baffle, and the second rotating shaft is rotatably connected to the conveying channel. The axis of the second rotating shaft is parallel to the axis of the first rotating shaft. The transmission belt is wound around the first and second rotating shafts. The baffle is located below the first cylinder and inside the conveying channel, and is used to prevent the live joint from continuing to pass through the conveying channel. When the piston rod of the first cylinder retracts, the baffle abuts against the lowest live joint inside the conveying channel. The piston rod of the first cylinder is directly opposite the center position of the second to last live joint inside the conveying channel. When the piston rod of the first cylinder extends, the baffle does not block the live joint, and the piston rod of the first cylinder passes through the original second to last live joint.

[0014] By adopting the above technical solution, each time the piston rod of the first cylinder moves back and forth, it can control the drop of one live joint, so that there is only one live joint in the passage at any time, reducing the mutual influence between multiple live joints, and making it easier for the feeding device to move the live joint in the passage to the connection end sleeved on the main pipe.

[0015] Preferably, the feeding device includes a second cylinder, a driving rod, and a linkage. The second cylinder is fixed on the worktable. The length direction of the piston rod of the second cylinder is parallel to the length direction of the main pipe and is positioned directly opposite the main pipe. The second cylinder is located on the side of the passageway away from the main pipe. The driving rod is mounted on the piston rod of the second cylinder. The linkage is used to drive the union joint to move together with the driving rod. When the piston rod of the second cylinder extends, the driving rod passes through the union joint and extends into the main pipe. Under the action of the linkage, the union joint moves together with the piston rod of the second cylinder to the connecting end sleeved on the main pipe.

[0016] By adopting the above technical solution, when the union moves into the passage, the piston rod of the second cylinder extends, and the driving rod passes through the middle of the union and then extends into the main pipe. At this time, the linkage drives the union to move together with the driving rod, and the driving rod can drive the union to move toward the main pipe side to the connection end sleeved on the main pipe.

[0017] Preferably, the linkage includes multiple first abutment blocks, multiple second abutment blocks, and a moving rod. The moving rod is slidably connected to the driving rod along a length direction parallel to the driving rod. The multiple first abutment blocks and multiple second abutment blocks are respectively close to both ends of the moving rod along its length direction. The first abutment block is located on the side of the second abutment block away from the second cylinder. The first abutment block and the second abutment block are slidably connected to the driving rod along a length direction perpendicular to the driving rod. Both the first abutment block and the second abutment block have inclined surfaces on their sides facing the moving rod. The distance between the inclined surface of the first abutment block and the moving rod gradually decreases from the end near the second cylinder to the end away from the second cylinder. The distance between the inclined surface of the second abutment block and the moving rod gradually increases from the end near the second cylinder to the end away from the second cylinder. The moving rod is provided with a first spring to drive the moving rod to always move towards the first abutment block until the end of the first abutment block extends out of the moving rod. The second abutment block is provided with a second spring to drive the second abutment block to move into the driving rod.

[0018] The outer diameter of the driving rod is equal to the inner diameter of the main pipe. When the piston rod of the second cylinder extends, the driving rod passes through the main pipe. The first abutting block moves toward the moving rod side to drive the moving rod to move toward the second abutting block side. The ends of the multiple second abutting blocks extend out of the driving rod and abut against the inner wall of the hexagonal nut.

[0019] By adopting the above technical solution, during the extension of the piston rod of the second cylinder, the driving rod first passes through the union, and then the driving rod passes through and slides on the main pipe. The main pipe will squeeze the first abutment block toward the moving rod until it is completely inside the driving rod. At this time, the moving rod moves toward the second abutment block under the action of the inclined surface of the first abutment block, thereby driving the ends of multiple second abutment blocks to move out of the driving rod and abut against the inner wall of the hexagonal nut. Through the friction between the second abutment block and the hexagonal nut, the union and the driving rod move together.

[0020] Preferably, a second limiting ring is coaxially sleeved on the drive rod. The outer diameter of the second limiting ring is larger than the inner diameter of the hexagonal nut and smaller than the outer diameter of the hexagonal nut. The second limiting ring is located on the side of the second abutment block away from the first abutment block. When the piston rod of the second cylinder extends, the second abutment block abuts against the end face of the main pipe facing the second cylinder, and the second limiting ring abuts against the end face of the hexagonal nut away from the hollow tube. At this time, the hollow tube is positioned opposite the two diameter reduction blocks.

[0021] By adopting the above technical solution, the cooperation between the second limiting ring and the second abutment block can drive the union to move to the set fixed position, so that the hollow tube on the union can be set directly opposite the two diameter reduction blocks, thereby improving the diameter reduction quality of the hollow tube.

[0022] Preferably, it further includes a rotating device, which includes a second rack, an internal ratchet gear, a rotating rod, a first frustum and a second frustum. The driving rod is coaxially rotatably connected to the piston rod of the second cylinder. The internal ratchet gear includes an internal ratchet with a unidirectional rotating inner circle and a gear ring. The gear ring is coaxially fixedly sleeved on the circumferential outer wall of the outer circle of the internal ratchet. The second rack is fixed on one of the reducing blocks. The moving direction of the reducing block is perpendicular to the axial direction of the driving rod. The gear ring is rotatably connected to the worktable. The second rack is meshed with the gear ring. The rotating rod is coaxially fixedly connected to the inner circle of the internal ratchet. When the reducing block moves away from the live joint, the rotating rod rotates unidirectionally. The first frustum is coaxially fixed on the rotating rod, and the second frustum is coaxially fixed on the driving rod. When the piston rod of the second cylinder extends, the outer wall of the first frustum adheres to the outer wall of the second frustum. The rotation of the first frustum can drive the second frustum to rotate.

[0023] By adopting the above technical solution, when the reducing block moves away from the union, it will drive the inner circle of the inner ratchet to rotate, thereby driving the first truncated cone to rotate through the rotating rod. The first truncated cone is attached to the second truncated cone and drives the second truncated cone to rotate through friction. The second truncated cone drives the union to rotate through the driving rod. After the union rotates, it drives the reducing block to reduce the diameter of the union again. This allows the reducing block to act on different positions of the hollow tube, thereby improving the diameter reduction quality of the hollow tube.

[0024] Preferably, the positioning device includes a positioning platform, a barrier plate, a second driving component, and two positioning plates. The barrier plate has a passage for the main pipe connection end to pass through. The positioning platform and the two positioning plates are located on both sides of the passage. The positioning platform is slidably connected to the worktable along a sliding direction perpendicular to the reducing block. The positioning platform has a placement groove matching the live joint. The positioning plates are slidably connected to the barrier plate along a sliding direction parallel to the reducing block. The two positioning plates are located on both sides of the main pipe. The two positioning plates have arc-shaped grooves matching the main pipe connection end on their opposite sides. The second driving component drives the two positioning plates to move toward the side that is closer to or further away from each other. When the connection end of the main pipe passes through the passage, the second driving component drives the two positioning plates to clamp the connection end to fix the position of the live joint on the worktable. The outer wall of the connection end abuts against the inner wall of the arc-shaped groove.

[0025] By adopting the above technical solution and setting up a baffle plate, the diameter reduction process can be isolated separately, thereby protecting the workers who place the live joint on the positioning table and control the movement of the positioning table.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] By setting up a positioning device and a reducing block, the positioning device fixes the body on the worktable. Then, the operator puts the union on the connection end of the main pipe. The two reducing blocks squeeze the hollow tube part of the union, so that the inner diameter of one end of the hollow tube is squeezed to the size of the standard part, which can improve the connection quality between the union and the main pipe.

[0028] By setting up a baffle plate, the diameter reduction process can be isolated, thereby protecting the workers who place the live joint on the positioning table and control the movement of the positioning table. Attached Figure Description

Detailed Implementation

[0041] The following is in conjunction with the appendix Figure 2-11 This application will be described in further detail.

[0042] This application discloses a riveting device for a water distributor joint.

[0043] Reference Figure 2 , Figure 3 The water distributor fitting and riveting equipment in this embodiment includes a workbench 6 and a positioning device 2, a material conveying device 3, a feeding device 4 and a diameter reduction device 5 arranged on the workbench 6.

[0044] Reference Figure 4The water distributor 1 includes a union joint 12 and a body 11. The body 11 includes a main pipe 111 and multiple branch pipes 112. One end of each branch pipe 112 is connected to the main pipe 111, and the multiple branch pipes 112 are located on the same side of the main pipe 111 and on the same plane. One end of the main pipe 111 is a connecting end 13, and a first limiting ring 131 is coaxially sleeved on the connecting end 13. The first limiting ring 131 is integrally formed with the main pipe 111. The union joint 12 is used to movably connect to the connecting end 13. The union joint 12 includes a hexagonal nut 122 and a hollow tube 121. One end of the hollow tube 121 is coaxially fixed to one side of the hexagonal nut 122. The hollow tube 121 and the hexagonal nut 122 are integrally formed. The inner diameter of the hollow tube 121 is equal to the inner diameter of the hexagonal nut 122, and the inner diameter of the hollow tube 121 is larger than the outer diameter of the first limiting ring 131.

[0045] Reference Figure 4 The connection method between the union 12 and the main pipe 111 is as follows: the end of the hollow tube 121 away from the hexagonal nut 122 is aligned with the first limiting ring 131 and put on the connecting end 13. Then, force is applied to the end of the hollow tube 121 away from the hexagonal nut 122, so that the inner diameter of the end of the hollow tube 121 away from the hexagonal nut 122 gradually shrinks to be smaller than the outer diameter of the first limiting ring 131, so that the union 12 cannot be separated from the main pipe 111.

[0046] Reference Figure 2 , Figure 3 The positioning device 2 is used to fix the body 11 on the workbench 6. The material conveying device 3 is used to transport the union 12 to the feeding device 4. The feeding device 4 is used to put the union 12 onto the connecting end 13 of the main pipe 111. The diameter reduction device 5 is used to reduce the diameter of the hollow tube 121 of the union 12 that is put onto the connecting end 13.

[0047] Reference Figure 2 , Figure 5The positioning device 2 includes a positioning platform 21, a baffle plate 22, a driving component 23, and two positioning plates 24. The baffle plate 22 is vertically fixed on the worktable 6. The baffle plate 22 has a passage 221 for the connecting end 13 of the main pipe 111 to pass through. The positioning platform 21 is located on one side of the thickness direction of the baffle plate 22, and the thickness direction of the baffle plate 22 is horizontal. The positioning platform 21 is slidably connected to the worktable 6 along a direction parallel to the thickness direction of the baffle plate. A third cylinder 25 is fixed on the worktable 6. The third cylinder 25 is located on the side of the positioning platform 21 away from the baffle plate 22. The length direction of the piston rod of the third cylinder 25 is parallel to the moving direction of the positioning platform 21 and is fixed on the positioning platform 21. A placement groove 211 matching the main body 11 is opened on the top surface of the positioning platform 21. When the main body 11 is placed in the placement groove 211, the length direction of the main pipe 111 is parallel to the moving direction of the positioning platform 21, and the connecting end 13 of the main pipe 111 extends out of the positioning platform 21 toward the passage 221. When the piston rod of the third cylinder 25 retracts, the entire body 11 is located on the side of the passage 221 close to the positioning table 21. When the piston rod of the third cylinder 25 extends, the connecting end 13 of the main pipe 111 extends out of the passage 221.

[0048] Reference Figure 5 Two positioning plates 24 are slidably connected to the side of the barrier plate 22 away from the positioning table 21 along a sliding direction perpendicular to the positioning plate 24. The two positioning plates 24 are arranged facing each other and located on both sides of the main pipe 111. The second driving component 23 drives the two positioning plates 24 to move toward the side that is closer to or farther away from each other. The side of the positioning plates 24 facing each other is provided with arc-shaped grooves 241 that match the connecting end 13 of the main pipe 111. The second driving component 23 consists of two fourth cylinders 231. The two fourth cylinders 231 are fixed on the worktable 6 and located on both sides of the two positioning plates 24. The length direction of the piston rod of the fourth cylinder 231 is parallel to the sliding direction of the positioning plate 24 and is fixed on the nearest positioning plate 24.

[0049] Reference Figure 2 , Figure 5 When the piston rod of the third cylinder 25 extends and the piston rod of the fourth cylinder 231 retracts, the connecting end 13 of the main pipe 111 moves to face the two positioning plates 24. Then the piston rod of the fourth cylinder 231 extends, the two positioning plates 24 clamp the connecting end 13, and the outer wall of the connecting end 13 abuts against the inner wall of the arc groove 241.

[0050] Reference Figure 5 , Figure 6Since the connecting end 13 of the main pipe 111 is fixed, in order to fix the main pipe 111 more stably on the worktable 6, two clamping rods 26 are rotatably connected on the moving platform. One end of the clamping rod 26 is inserted and fixed with a rotating roller 261. The rotating roller 261 is rotatably connected in the positioning platform 21 along the moving direction parallel to the positioning platform 21. The length direction of the rotating roller 261 is perpendicular to the length direction of the clamping rod 26. When the main body 11 is placed on the positioning platform 21, the two rotating rollers 261 are located on both sides of the main pipe 111. The moving platform is provided with a driving component 27. The driving component 27 drives the two clamping rods 26 to rotate toward the side of the main pipe 111 until they abut against the outer wall of the main pipe 111, pressing the end of the main pipe 111 away from the connecting section against the positioning platform 21.

[0051] Reference Figure 5 , Figure 6 The driving component 27 includes a main roller 272, a main gear 274, a main rack 275, a first bevel gear 276, two second bevel gears 277, two conveyor belts 271, and two auxiliary rollers 273. The main roller 272 is rotatably connected to the positioning table 21 in the vertical direction. The main gear 274 is coaxially fixed to the bottom end of the main roller 272. The main rack 275 is fixed to the worktable 6. The length direction of the main rack 275 is parallel to the sliding direction of the positioning table 21. The main gear 274 is meshed with the main rack 275. The first bevel gear 276 is coaxially sleeved on the main roller 272. Two auxiliary rollers 273 are located on both sides of the main roller 272 and are rotatably connected to the positioning table 21 along an axis parallel to the rotating roller 261. Two second bevel gears 277 are coaxially fixedly connected to the two auxiliary rollers 273. A first bevel gear 276 meshes with the second bevel gear 277. The conveyor belt 271 is wound around the corresponding rotating roller 261 and the corresponding auxiliary roller 273. When the piston rod of the third cylinder 25 extends, the two clamping rods 26 rotate toward the main pipe 111 until they abut against the main pipe 111. When the piston rod of the third cylinder 25 retracts, the two clamping rods 26 rotate toward the side away from the main pipe 111.

[0052] Reference Figure 7 , Figure 8The material conveying device 3 includes a vibratory feeder 31 and a conveying channel 32 connected at both ends. The conveying channel 32 is fixed on the workbench 6, and the vibratory feeder 31 is placed on the ground for use. The workbench 6 is fixed with a passageway 33 for the passage of the swivel joints 12. The passageway 33 is located on the side of the baffle plate 22 away from the positioning table 21. When the main body 11 is fixed on the workbench 6 by the positioning device 2, the passageway 33 is set directly opposite the connection end 13 of the main pipe 111. One end of the conveying channel 32 is connected to the vibratory feeder 31, and the other end of the conveying channel 32 is connected to the passageway 33. The height of the conveying channel 32 gradually decreases from the end near the vibratory feeder 31 to the end near the passageway 33. The vibratory feeder 31 is used to automatically orient and sort multiple swivel joints 12 and transport them into the conveying channel 32. The swivel joints 12 in the conveying channel 32 automatically roll along the conveying channel 32 into the passageway 33. When the union 12 rolls into the passageway 33, the axis of the union 12 is parallel to the axis of the main pipe 111, and the hollow tube 121 on the union 12 is positioned facing the main pipe 111. The length of the passageway 33 is parallel to the length of the main pipe 111, and the feeding device 4 is used to move the union 12 in the passageway 33 onto the connecting end 13 fitted onto the main pipe 111.

[0053] Reference Figure 3 , Figure 7 The diameter reduction device 5 includes a drive component 51 and two diameter reduction blocks 52. The two diameter reduction blocks 52 are arranged facing each other and are located on both sides of the hollow tube 121 sleeved on the main pipe 111. The diameter reduction blocks 52 are slidably connected to the worktable 6 along a sliding direction parallel to the positioning plate 24. The drive component 51 drives the two diameter reduction blocks 52 to move closer to or further away from each other. The drive component 51 consists of two fifth cylinders 511, each corresponding to one of the two diameter reduction blocks 52. The piston rods of the fifth cylinders 511 are parallel to the moving direction of the diameter reduction blocks 52 and fixed to the corresponding diameter reduction blocks 52. A union groove 521 matching the standard part of the union joint 12 after the union of the main pipe 111 is provided on the side of the two diameter reduction blocks 52 facing each other. (Refer to...) Figure 3 , Figure 4 When the two reducing blocks 52 move to abut against each other, the inner diameter of the end of the hollow tube 121 away from the hexagonal nut 122 is squeezed by the two reducing blocks 52 to be smaller than the outer diameter of the first limiting ring 131.

[0054] Reference Figure 7 , Figure 8A material discharge device 34 is provided on the material conveying channel 32. The material discharge device 34 is used to control the individual rolling of the union joint 12 in the material conveying channel 32 into the passageway 33. The material discharge device 34 includes a first rack 341, a first gear 342, a transmission belt 343, a first cylinder 344, and a baffle 345. The first cylinder 344 is fixed on the worktable 6. The piston rod of the first cylinder 344 is set towards the side of the material conveying channel 32. The inner diameter of the piston rod of the first cylinder 344 is smaller than the inner diameter of the union joint 12. A through hole is opened on the side wall of the material conveying channel 32 for the piston rod of the first cylinder 344 to extend into the interior of the material conveying channel 32. The length direction of the piston rod of the first cylinder 344 is parallel to the sliding direction of the positioning table 21. The part of the material conveying channel 32 facing the first cylinder 344 is vertically arranged. When the union joint passes through the first cylinder 344, the axial direction of the union joint is parallel to the length direction of the piston rod of the first cylinder 344.

[0055] Reference Figure 7 , Figure 8 A first rotating shaft 3421 is rotatably connected to the conveying channel 32. The first rotating shaft 3421 is located below the first cylinder 344, and the axial direction of the first rotating shaft 3421 is perpendicular to the length direction of the piston rod of the first rotating shaft 3421. A first rack 341 is fixed to the piston rod of the first cylinder 344 along a direction parallel to the length direction of the piston rod of the first cylinder 344. A first gear 342 is coaxially sleeved and fixed to the first rotating shaft 3421, and the first rack 341 is meshed with the first gear 342. A second rotating shaft 3451 is rotatably connected to the conveying channel 32 along a direction parallel to the axial direction of the first rotating shaft 3421. The second rotating shaft 3451 is located below the first rotating shaft 3421. A transmission belt 343 is wound around the first rotating shaft 3421 and the second rotating shaft 3451. One end of a baffle 345 is fixed to the second rotating shaft 3451. The baffle 345 is located inside the conveying channel 32 and is used to prevent the live joint 12 from continuing to pass through the conveying channel 32.

[0056] Reference Figure 7 , Figure 8 When the piston rod of the first cylinder 344 retracts, the baffle 345 abuts against the lowest union 12 in the conveying channel 32. At this time, the piston rod of the first cylinder 344 is roughly aligned with the center of the second-to-last union 12 from the bottom in the conveying channel 32. When the piston rod of the first cylinder 344 extends, the baffle 345 rotates until it no longer obstructs the union 12. The lowest union 12, which was originally located in the conveying channel 32, continues to move along the conveying channel 32 into the passageway 33. The piston rod of the first cylinder 344 passes through the original second-to-last union 12, which is restricted by the piston rod of the first cylinder 344 and cannot fall down in the conveying channel 32.

[0057] Reference Figure 9 , Figure 10The feeding device 4 includes a second cylinder 41, a drive rod 42, and a linkage 43, as shown in the reference. Figure 7 , Figure 10 The second cylinder 41 is fixed on the worktable 6. Taking the main pipe 111 fixed on the worktable 6 as a reference, the length direction of the piston rod of the second cylinder 41 is parallel to the length direction of the main pipe 111 and is directly opposite to the main pipe 111. The second cylinder 41 is located on the side of the passageway 33 away from the main pipe 111. The outer diameter of the piston rod of the second cylinder 41 is equal to the inner diameter of the main pipe 111. The driving rod 42 is coaxially rotatably connected to the piston rod of the second cylinder 41. The linkage 43 is used to drive the union 12 to move together with the driving rod 42. When the piston rod of the second cylinder 41 extends, the driving rod 42 passes through the middle of the union 12 in the passageway 33 and extends into the main pipe 111. The driving rod 42 can slide in the main pipe 111. Under the action of the linkage 43, the union 12 moves together with the piston rod of the second cylinder 41 to the connecting end 13 sleeved on the main pipe 111.

[0058] Reference Figure 9 , Figure 10 The linkage 43 includes a movable rod 431, multiple first abutment blocks 432, and multiple second abutment blocks 433. The movable rod 431 is slidably connected to the driving rod 42 along a length direction parallel to the driving rod 42. The movable rod 431 and the driving rod 42 are coaxially arranged. A first limiting block 4311 is fixed on the outer wall of the movable rod 431. A first limiting groove 421 is opened on the driving rod 42. The first limiting block 4311 is slidably connected to the first limiting groove 421 along a sliding direction parallel to the movable rod 431. The multiple first abutment blocks 432 are located near the end of the movable rod 431 that is away from the second cylinder 41 along its length direction. The multiple second abutment blocks 433 are located near the end of the movable rod 431 that is away from the first cylinder 344 along its length direction. Both the first abutment blocks 432 and the second abutment blocks 433 are slidably connected to the driving rod 42 along a length direction perpendicular to the driving rod 42. A second limiting block 4321 is fixed to the outer wall of the first abutment block 432. A second limiting groove 422 is provided on the driving rod 42. The second limiting block 4321 is slidably connected to the second limiting groove 422 along the sliding direction perpendicular to the moving rod 431. Multiple first abutment blocks 432 are evenly distributed on the driving rod 42 along the circumferential direction. A third limiting block 4331 is fixed to the outer wall of the second abutment block 433. A third limiting groove 423 is provided on the driving rod 42. The third limiting block 4331 is slidably connected to the third limiting groove 423 along the sliding direction perpendicular to the moving rod 431. Multiple second abutment blocks 433 are evenly distributed on the driving rod 42 along the circumferential direction.

[0059] Reference Figure 9 , Figure 10Both the first abutment block 432 and the second abutment block 433 have inclined surfaces 44 on their sides facing the moving rod 431. The distance between the inclined surface 44 on the first abutment block 432 and the axis of the driving rod 42 gradually decreases from the end near the second cylinder 41 to the end away from the second cylinder 41. The distance between the inclined surface 44 on the second abutment block 433 and the axis of the driving rod 42 gradually increases from the end near the second cylinder 41 to the end away from the second cylinder 41. The inclined surfaces 44 on both the first abutment block 432 and the second abutment block 433 abut against the ends of the moving rod 431.

[0060] Reference Figure 7 , Figure 10 A first spring 4211 is provided on the first limiting block 4311. The two ends of the first spring 4211 abut against the side of the first limiting block 4311 away from the first abutting block 432 and the end wall of the first limiting groove 421 away from the first abutting block 432, respectively. The first spring 4211 is always in a compressed state. When no external force is applied to the first abutting block 432, the moving rod 431 always moves towards the side of the first abutting block 432 until the end of the first abutting block 432 moves out of the driving rod 42. The end of the first abutting block 432 is provided with a rounded corner. Applying force to the first abutting block 432 from any direction can drive the first abutting block 432 to move towards the side of the moving rod 431.

[0061] Reference Figure 9 , Figure 10 The second abutment block 433 is provided with a second spring 4231. The two ends of the second spring 4231 abut against the end of the third limiting groove 423 away from the moving rod 431 and the third limiting block 4331, respectively. The second spring 4231 is always in a compressed state. When the moving rod 431 moves toward the side of the first abutment block 432 to drive the end of the first abutment block 432 to move out of the driving rod 42, the second abutment block 433 moves under the action of the second spring 4231 until it is completely located inside the driving rod 42.

[0062] Reference Figure 9 , Figure 10 During the extension of the piston rod of the second cylinder 41, the driving rod 42 first passes through the union joint 12, and then the driving rod 42 passes through and slides on the main pipe 111. The main pipe 111 will drive the first abutment block 432 to move towards the moving rod 431 until it is completely inside the driving rod 42. At this time, the moving rod 431 moves towards the second abutment block 433 under the action of the inclined surface 44 of the first abutment block 432, thereby driving the ends of multiple second abutment blocks 433 to move out of the driving rod 42 and abut against the inner wall of the hexagonal nut 122. Through the friction between the second abutment block 433 and the hexagonal nut 122, the union joint 12 and the driving rod 42 move together.

[0063] Reference Figure 9 , Figure 10 A second limiting ring 424 is coaxially sleeved on the driving rod 42. The second limiting ring 424 is located on the side of the second abutment block 433 away from the first abutment block 432. The outer diameter of the second limiting ring 424 is larger than the inner diameter of the hexagonal nut 122 but smaller than the outer diameter of the hexagonal nut 122. When the piston rod of the second cylinder 41 is fully extended, the second abutment block 433 abuts against the end face of the main pipe 111 facing the second cylinder 41, and the second limiting ring 424 abuts against the end face of the hexagonal nut 122 away from the hollow tube 121. At this time, the hollow tube 121 is positioned directly opposite the two diameter reduction blocks 52. (Refer to...) Figure 7 , Figure 10 The cooperation between the second limiting ring 424 and the second abutment block 433 can drive the union 12 to move to a fixed position each time. At the same time, the union 12 and the main pipe 111 are coaxially arranged, and the union 12 is not easy to move. This allows the hollow tube 121 on the union 12 to be aligned with the two diameter reduction blocks 52, thereby improving the diameter reduction quality of the hollow tube 121.

[0064] Reference Figure 3 , Figure 11 The worktable 6 is equipped with a rotating device 45, which drives the drive rod 42 to rotate. The rotating device 45 includes a second rack, an inner ratchet 455 gear 451, a rotating rod 452, a first frustum 453 and a second frustum 454. The inner ratchet 455 gear 451 includes an inner ratchet 455 and a gear ring 456. The inner ratchet 455 includes an inner circle 4551, an outer circle 4552 and a ratchet structure 4553 connecting the inner circle 4551 and the outer circle 4552. The inner circle 4551 can only rotate with the outer circle 4552 when the outer circle 4552 rotates in the correct direction. Therefore, the inner circle 4551 can only rotate in one direction. A gear ring 456 is coaxially fixedly sleeved on the circumferential outer wall of the outer circle 4552 of the inner ratchet 455. A rotating rod 452 is rotatably connected to the worktable 6, with its axis parallel to the axis of the driving rod 42. One end of the rotating rod 452 is coaxially fixedly connected to the inner circle 4551 of the inner ratchet 455, and the other end is coaxially fixedly connected to the first frustum 453. The first frustum 453 gradually narrows from the end furthest from the second cylinder 41 to the end closest to the second cylinder 41. A second rack is fixed along the direction of movement parallel to the reducing block 52 to the piston rod of the fifth cylinder 511 on the side furthest from the conveyor 32, and the second rack is meshed with the gear ring 456. A second frustum 454 is coaxially fixed to the driving rod 42, and the second frustum 454 gradually narrows from the end closest to the second cylinder 41 to the end furthest from the second cylinder 41. When the piston rod of the second cylinder 41 extends, the second truncated cone 454 moves with the drive rod 42 until its outer wall abuts against and fits against the outer wall of the first truncated cone 453.

[0065] Reference Figure 3 , Figure 10 Both the first frustum 453 and the second frustum 454 are made of rubber. When the first frustum 453 and the second frustum 454 come into contact with each other, they can rotate synchronously under the action of friction. When the piston rod of the fifth cylinder 511 extends, the two reducing blocks 52 reduce the diameter of the hollow tube 121. At this time, the outer circle 4552 rotates without driving the inner circle 4551 to rotate. When the piston rod of the fifth cylinder 511 retracts, the two reducing blocks 52 move away from the hollow tube 121. At this time, the rotation of the outer circle 4552 will drive the inner circle 4551 to rotate, thereby driving the first frustum 453 to rotate through the rotating rod 452. The first frustum 453 is attached to the second frustum 454 and drives the second frustum 454 to rotate through friction. The second frustum 454 drives the union 12 to rotate through the driving rod 42. The union 12 rotates 90 degrees each time. Then the piston rod of the fifth cylinder 511 is driven to extend again, and the reducing blocks 52 are driven to reduce the diameter of the union 12 again. This allows the reducing blocks 52 to act on different positions of the hollow tube 121, thereby improving the diameter reduction quality of the hollow tube 121.

[0066] The implementation principle of the water distributor fitting and riveting device in this application embodiment is as follows: the positioning device 2 is used to fix the body 11 on the workbench 6, the material conveying device 3 is used to transport the fitting 12 to the feeding device 4, the feeding device 4 is used to fit the fitting 12 onto the connecting end 13 of the main pipe 111, and the diameter reduction device 5 is used to reduce the diameter of the hollow tube 121 of the fitting 12 fitted onto the connecting end 13.
