[0001] This invention relates to the field of heat exchanger tube production and assembly technology, specifically an automated cutting and assembly device for heat exchanger tubes. Background Technology

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid. It is also called a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used. Heat exchangers are connected by multiple heat exchanger tubes to achieve the purpose of heat exchange while conducting liquid conduction.

During cutting, it is also necessary to ensure the stability of the tube body and adjust the cutting angle to adapt to different heat exchanger assembly structures. Therefore, improvements are needed to address these issues. Summary of the Invention

[0014] Specifically, the limiting support component includes a conical guide frame, on which a control and guiding unit is provided. The conical guide frame is also fixed to a fixed plate, which is fixed to a first guide slot frame. A photoelectric measuring instrument is fixedly installed on the top of the fixed plate. The control and guiding unit adjusts the guide push rod, spring telescopic sleeve rod, and connecting wheel to slide on the conical guide frame and the first guide slot frame, thereby pushing the heat exchanger tube to adjust its position.

[0015] Specifically, the control and guidance unit includes a slot frame, within which an independent motor controls the rotation of a lead screw. A connecting guide is threaded onto the lead screw, and a spring telescopic sleeve is fixedly mounted on the connecting guide. A guide push rod is telescopically connected to the center of the spring telescopic sleeve, and a connecting wheel is rotatably sleeved at the bottom of the guide push rod. An installation plate is fixedly mounted on the side of the slot frame, and a second electrically controlled telescopic rod is mounted on the installation plate.

The lower end of the telescopic compression rod is hinged to the mating rod, and the side end of the mating rod is fixed to the fixed mating block. The connecting guide slides within the slot frame. The swing arm drives the telescopic compression rod to swing and adjust via the second hinge shaft, thereby limiting the compression of the heat exchanger tubes. The adjusting rod drives the spring telescopic rod to slide and adjust on the fixed connecting block via the adjusting disc and the first hinge shaft, thus limiting the compression of the heat exchanger tubes.

[0016] Specifically, the cutting assembly structure includes a cutting component and an assembly component. The assembly component is fixedly mounted on the side of the cutting component.

[0018] The extension and retraction of the third electrically controlled telescopic rod drives the welding machine base, fixed mating plate, plasma cutting gun base, rotating control disc, rotating control shaft, fourth gear disc, and rotating adjustment frame to move, so that the fourth gear disc rotates and adjusts on the docking ring frame. At the same time, the second electrically controlled telescopic seat controls the movement of the gear frame, so that the gear frame and the fourth gear disc are limited and engaged, controlling the rotation of the fourth gear disc.

[0019] Specifically, the power switching mechanism includes a third electrically controlled telescopic seat, which controls the extension and retraction of the connecting support rod frame. An electric motor is fixedly mounted on the connecting support rod frame, and a sixth gear plate and a fifth gear plate are driven and connected to the electric motor.

[0021] Specifically, the assembly components include a support base block, on which a connecting support plate block is telescopically connected via an electro-hydraulic seat. A rotation control seat is fixedly sleeved on the connecting support plate block, and a heat exchanger docking plate is connected to the upper limit of the rotation control seat.

The side end of the support frame is fixed to the lower end of the guide transmission seat. There are two guide channels. The guide transmission seat is connected to the guide channel at the rear end. The guide channels at both the front and rear ends are connected to the guide docking seat. The guide docking seat is connected to the first guide slot frame.

[0022] The beneficial effects of this invention are:

[0023] First, this invention guides and transmits heat exchanger tubes through a guided transmission structure. The heat exchanger tubes can be placed on a storage base. The up-and-down movement of the guiding component drives the heat exchanger tubes to move, allowing them to pass through the fixed plate step by step to the guided transmission base. As the guided transmission base moves and adjusts, the first electrically controlled telescopic base extends and retracts, controlling the movement of the pusher frame and connecting rod on the guided transmission base. This pushes the heat exchanger tubes to the diversion and limiting structure for diversion and conduction, thereby achieving continuous guided transmission.

[0024] Second, this invention facilitates guiding and limiting operations through the design of a diversion and limiting structure. The diversion and guiding component adopts a dual-channel configuration. Through the pusher frame and connecting rod, the heat exchanger tubes are guided through the flat plate frame to the front guide channel. The transmission is then guided by the guide docking seat. An infrared sensor detects the position of the heat exchanger tubes. The first electrically controlled telescopic rod controls the flat plate frame, connecting inclined rod, and docking guide block to achieve the blocking and guiding of the heat exchanger tubes, thereby guiding the heat exchanger tubes to different first guide slots. A photoelectric measuring instrument is used for length measurement, and simultaneously controls... The control and guiding unit can push the heat exchanger tubes to slide on the first guide slot. The control and guiding unit also limits the heat exchanger tubes through a spring telescopic rod or a telescopic compression rod to ensure the stability of the heat exchanger tubes during processing. At the same time, the power switching mechanism can switch to guide the second or third toothed disc and realize the control operation. In addition, the tapered design of the tapered guide frame allows the guide push rod to be lower than the right side when it is in the left position of the first guide slot, which facilitates the subsequent disengagement of the guide push rod from the heat exchanger tube and facilitates automated transfer production.

[0025] Third, this invention, through the design of the cutting assembly structure, enables the cutting of heat exchanger tubes. The rotating cutting mechanism drives the entire plasma cutting unit to rotate, achieving ring-shaped cutting. Furthermore, the second guide slot has a break at the cutting position to prevent interference with the cutting process. Simultaneously, the third electrically controlled telescopic rod extends and retracts, changing the tilt angles of the welding machine base, the fixed mating plate, and the plasma cutting gun base. The second electrically controlled telescopic base and the toothed frame provide real-time limiting to ensure stability, thus enabling oblique cutting. The plasma cutting gun base also employs a telescopic design. By changing the position of the plasma cutting torch, the distance between the plasma cutting torch and the heat exchanger tubes can be adjusted. The assembly components can be set to pull the heat exchanger tubes to slide, allowing the heat exchanger tubes to have an interference fit with the heat exchanger mating plate, thus achieving continuous docking and assembly work. This facilitates automated production. Through the combination of the guiding and conveying structure, the diversion and limiting structure, and the cutting and assembly structure, the material guiding-cutting-assembly process is integrated into a production process, facilitating automated cutting and assembly work and achieving efficient heat exchanger production. At the same time, the cutting angle can be adjusted to adapt to different heat exchanger assembly structures. Attached Figure Description

[0045] The invention will be further described below with reference to the accompanying drawings.

[0046] Example

[0047] like Figure 1-16 As shown, an automated cutting and assembly device for heat exchanger tubes according to the present invention includes a guiding and transmission structure 1, a diversion and limiting structure 2, and a cutting and assembly structure 3. The diversion and limiting structure 2 is fixedly connected to the side end of the guiding and transmission structure 1, and the cutting and assembly structure 3 is fixedly connected to the side end of the diversion and limiting structure 2. Through the setting of the guiding and transmission structure 1, the heat exchanger tube 63 is guided and transmitted. The heat exchanger tube 63 can be placed on the storage seat 7. Through the up and down movement of the guiding component 5, the heat exchanger tube 63 is driven to move, so that the heat exchanger tube 63 passes through the fixed plate 6 step by step to the guiding and transmission seat 4. As the guiding and transmission seat 4 moves and adjusts, the first electrically controlled telescopic seat 10 controls the pusher frame 8 and the connecting rod 9 to move on the guiding and transmission seat 4 by telescoping, which can push the heat exchanger tube 63 to the diversion and limiting structure 2 for diversion and conduction, thereby achieving the purpose of continuous guiding and transmission.

[0048] The guide transmission structure 1 includes a storage base 7, on which a fixed plate 6 is fixedly connected. The fixed plate 6 has multiple pieces, and each pair is telescopically connected to a guide component 5. The top of the guide component 5 is connected to the guide transmission base 4. A first electrically controlled telescopic base 10 is fixedly installed on the side of the guide transmission base 4. The first electrically controlled telescopic base 10 controls the movement of the connecting rod 9 and the pusher frame 8 by telescopic movement. The pusher frame 8 and the connecting rod 9 are fixed.

[0049] The guide component 5 includes a movable plate 11, which is provided in multiple pieces. The movable plates 11 are fixed together by a connecting frame 12. A sliding block 14 is fixedly connected to the side of the top movable plate 11. The sliding block 14 slides on the limiting block 13. The side of the limiting block 13 is elastically adjusted by a spring guide rod 15. A stepper motor 16 is fixedly installed at the bottom of the limiting block 13. A transmission disk 17 is driven and connected to the stepper motor 16. A first connecting rod 18 is fixedly provided on the transmission disk 17. A second connecting rod 19 is hinged to the first connecting rod 18. The second connecting rod 19 is hinged to the bottom movable plate 11.

[0050] Stepper motor 16 controls the rotation of first link 18 and second link 19 via transmission disk 17, driving multiple movable plates 11 and connecting frame 12 to slide in a limited manner. This causes the movable plates 11 to slide longitudinally between fixed plates 6, pushing the heat exchanger tubes 63 upwards step by step. The heat exchanger tubes 63 are first stored on storage base 7. At this time, guide component 5 starts working, and stepper motor 16 drives transmission disk 17 to rotate. First link 18 is fixed at an eccentric position on transmission disk 17. Through first link 18, the hinged second link 19 moves, causing the second link 19 to move. The movable plate 11 is driven to move, and the movable plates 11 are interconnected through the connecting frame 12, which drives multiple movable plates 11 to move synchronously. When the movable plate 11 moves, the top movable plate 11 drives the sliding block 14 to move, so that the sliding block 14 slides and adjusts on the limiting block 13 and the spring guide rod 15 to perform longitudinal limiting, so that the movable plate 11 slides in the limited state. The movable plate 11 slides and adjusts longitudinally between the fixed plates 6, thereby pushing the heat exchanger tube 63 to be continuously transmitted to the fixed plate 6 until it reaches the guide transmission seat 4, and then it is transmitted along with the movement of the guide transmission seat 4.

[0051] The diversion and limiting structure 2 includes a diversion guide component 20 and a limiting support component 21. The limiting support component 21 is fixedly connected to the side end of the diversion guide component 20. The diversion guide component 20 includes a support frame 23, and a limiting mechanism 22 is fixedly mounted on the support frame 23. The limiting mechanism 22 includes a support side plate 33, and a support shaft 32 is fixedly connected to the center of the support side plate 33. A first electrically controlled telescopic rod 31 is fixedly mounted on the support shaft 32. The first electrically controlled telescopic rod 31 changes the position of the guide block by telescoping. The upper end of the guide block is fixed to the docking guide block 28. The docking guide block 28 is connected to... The diagonal brace 27 is fixed to the flat plate frame 26, which slides and adjusts between the second connecting rod 19. A guide channel 30 is connected to the front end of the fixed guide frame 29, and a guide docking seat 34 is connected to the side end of the guide channel 30. The guide docking seat 34 is fixed to the supporting side plate 33, and a mounting plate frame 24 is fixedly connected to the upper end of the guide docking seat 34. An infrared sensor 25 is fixedly installed on the mounting plate frame 24. The diversion and limiting structure 2 facilitates guide and limiting operations. The diversion and guiding component 20 adopts a dual-channel design, and can be pushed by the pusher frame 8 and connecting rod 9 to... The heat exchanger tube 63 is transmitted to the guide channel 30 at the front end through the plate frame 26, and then guided by the guide docking seat 34. The infrared sensor 25 senses the position of the heat exchanger tube 63. The first electrically controlled telescopic rod 31 controls the plate frame 26, the connecting diagonal rod 27, and the docking guide block 28 to achieve the blocking and guiding work of the heat exchanger tube 63, thereby guiding the heat exchanger tube 63 to different first guide slot frames 36. The photoelectric measuring instrument 39 is used for length measurement, and at the same time, it controls the guiding unit 35 to push the heat exchanger tube 63 to slide on the first guide slot frame 36. The control and guidance unit 35 also limits the heat exchanger tube 63 by means of spring telescopic rod 48 or telescopic compression rod 53 to ensure the stability of the heat exchanger tube 63 during processing. At the same time, the power switching mechanism 69 can switch to guide the second toothed disc 57 or the third toothed disc 70 and realize the control operation. Meanwhile, the tapered design of the tapered guide frame 38 allows the guide push rod 41 to be lower than the right side when it is in the left position of the first guide slot frame 36, which facilitates the subsequent disengagement of the guide push rod 41 from the heat exchanger tube 63 and facilitates automated transmission production.

[0052] Infrared sensor 25 is used to sense the heat exchanger tube 63, thereby controlling the operation of the first electrically controlled telescopic rod 31. The first electrically controlled telescopic rod 31, through extension and retraction, controls the movement of the flat plate frame 26 on the fixed guide frame 29, thus blocking and guiding the heat exchanger tube 63. The flat plate frame 26 can be adjusted to be flush with the fixed guide frame 29, or it can be adjusted to protrude from the upper end of the fixed guide frame 29. The diversion guide component 20 is fixed to the guide channel 30. The first electrically controlled telescopic base 10, through extension and retraction adjustment, controls the movement of the pusher frame 8 and connecting rod 9, causing the pusher frame 8 to push the heat exchanger tube 63, which can push the heat exchanger tube 63 to different positions on the guide channel 30. The switching of channels is controlled by the first electrically controlled telescopic rod 31. When extended, it drives the docking guide block 28 to move, and through the connecting diagonal rod 27, it drives the plate frame 26 to rise. At this time, the plate frame 26 protrudes from the surface of the fixed guide frame 29, blocking the heat exchanger tube 63. At this time, the heat exchanger tube 63 is transmitted on the guide channel 30 at the rear end. When the first electrically controlled telescopic rod 31 descends, it can control the plate frame 26 to descend, so that the plate frame 26 is flush with the fixed guide frame 29, so that the heat exchanger tube 63 is guided to the guide channel 30 at the front end through the plate frame 26 and the fixed guide frame 29. It is then guided and transmitted through the guide channel 30 at the front end. After that, the heat exchanger tube 63 can reach the limiting support component 21 through the guide docking seat 34. The infrared sensor 25 can detect the position of the heat exchanger tube 63, thereby analyzing the location of the heat exchanger tube 63.

[0053] The limiting support component 21 includes a conical guide frame 38, on which a control and guidance unit 35 is provided. The conical guide frame 38 is also fixed to a fixed plate 37, which is fixed to a first guide slot frame 36. A photoelectric measuring instrument 39 is fixedly installed on the top of the fixed plate 37. The control and guidance unit 35 adjusts the guide push rod 41, the spring telescopic sleeve rod 42, and the connecting wheel 43 to slide on the conical guide frame 38 and the first guide slot frame 36, thereby pushing the heat exchanger tube 63 to adjust its position.

[0054] The control and guidance unit 35 includes a slot frame 40. An independent motor controls the rotation of a lead screw 45 within the slot frame 40. A connecting guide frame 44 is threaded onto the lead screw 45. A spring telescopic sleeve 42 is fixedly mounted on the connecting guide frame 44. A guide push rod 41 is telescopically connected to the center of the spring telescopic sleeve 42. A connecting wheel 43 is rotatably sleeved at the bottom of the guide push rod 41. A mounting plate 59 is fixedly mounted on the side of the slot frame 40. A second electrically controlled telescopic rod 60 is mounted on the mounting plate 59. The second electrically controlled telescopic rod 60 controls the extension and retraction of an adapter toothed block 58. A second toothed disc 57 is located at the lower end of the adapter toothed block 58 and rotates at the center of the mounting plate 59. A first toothed disc 56 is meshed with the side end of the second toothed disc 57. A swing arm 55 and an adjusting docking rod 52 are fixedly connected to the first toothed disc 56. An adjusting plate 51 is fixedly connected to the side end of the adjusting docking rod 52. A spring telescopic rod 48 is hinged to the adjusting plate 51 via a first hinge shaft 46. A fixed connecting block 47 is hinged to the lower end of the spring telescopic rod 48. A telescopic extrusion rod 53 is hinged to the swing arm 55 via a second hinge shaft 54. The lower end of the telescopic extrusion rod 53 is hinged to the mating docking rod 50. The side end of the mating docking rod 50 is fixed to the fixed mating block 49. The connecting guide 44 slides within the slot frame 40. The swing arm 55 drives the telescopic extrusion rod 53 to swing and adjust via the second hinge shaft 54, thereby limiting the extrusion of the heat exchanger tube 63. The adjusting docking rod 52 drives the spring telescopic rod 48 to slide and adjust on the fixed connecting block 47 via the adjusting plate 51 and the first hinge shaft 46, thereby limiting the extrusion of the heat exchanger tube 63.

[0055] The cutting assembly structure 3 includes a cutting component 61 and an assembly component 62. The assembly component 62 is fixedly mounted on the side of the cutting component 61. The cutting component 61 includes a support platform 66, on which a second guide slot frame 67 is fixedly connected. A heat exchanger tube 63 is slidably mounted on the second guide slot frame 67. The support platform 66 is also fixed to a fixed collar frame 64. A rotating cutting mechanism 68 is rotatably mounted on the fixed collar frame 64 via a bearing ring 65. The rear end of the support platform 66 is fixedly connected to a power switching mechanism 69. The rotating cutting mechanism 68 includes a third gear plate 70, on which a docking ring frame 71 is fixedly connected. A second electrically controlled telescopic seat 73 is fixedly connected to the inner side of the docking ring frame 71. The second electrically controlled telescopic seat 73 controls the telescopic adjustment of the gear frame 74, allowing the gear frame 74 to extend and retract. 4. The plasma cutting unit 72 is in limited contact with the plasma cutting unit 72. The plasma cutting unit 72 swings and adjusts on the docking ring frame 71. Through the setting of the cutting assembly structure 3, the heat exchanger tube 63 can be cut. The rotating cutting mechanism 68 drives the plasma cutting unit 72 to rotate as a whole, which can realize the ring cutting operation. The second guide slot frame 67 has a discontinuity at the cutting position to prevent the second guide slot frame 67 from interfering with the cutting. At the same time, the third electrically controlled telescopic rod 76 changes the tilt angle of the welding machine base 78, the fixed mating plate 79, and the plasma cutting gun base 80 by telescopic movement. At the same time, the second electrically controlled telescopic seat 73 and the tooth frame 74 can limit the movement in real time to ensure stability, thereby performing oblique cutting. The plasma cutting gun base 80 also adopts a telescopic mechanism. The reduced design allows for adjustment of the distance between the plasma cutting torch and the heat exchanger tube 63 by changing the position of the plasma cutting torch. The assembly component 62 allows the heat exchanger tube 63 to slide, ensuring an interference fit between the heat exchanger tube 63 and the heat exchanger mating plate 91, enabling continuous assembly and facilitating automated production. The combination of the guide transmission structure 1, the diversion and limiting structure 2, and the cutting and assembly structure 3 integrates material guiding, cutting, and assembly into a unified production process, facilitating automated cutting and assembly and achieving high-efficiency heat exchanger production. It also allows for adjustment of the cutting angle to adapt to different heat exchanger assembly structures. Different guide channels 30 reach different first guide frames 36, at which point the control unit... The control unit 35 operates by rotating the lead screw 45 within it under the drive of an independent motor. This causes the connecting guide frame 44 to slide on the slot frame 40, changing the positions of the guide push rod 41, the spring telescopic sleeve 42, and the connecting wheel 43. The lower end of the connecting wheel 43 contacts the conical guide frame 38 and rotates on it. The connecting wheel 43 pushes the guide push rod 41 to elastically extend and retract on the spring telescopic sleeve 42, allowing the guide push rod 41 to protrude from the bottom of the first guide slot frame 36. This guides the heat exchanger tube 63 to slide on the first guide slot frame 36. The inclined arrangement of the conical guide frame 38 ensures that the guide push rod 41 reaches its highest point when it reaches the rightmost position and its lowest point when it reaches the leftmost position.This prevents the guide push rod 41 from colliding with the heat exchanger tube 63. The photoelectric measuring instrument 39 is used for detecting the length of the heat exchanger tube 63. The photoelectric measuring instrument 39 on the left is used to detect the overall length of the heat exchanger tube 63, and the photoelectric measuring instrument 39 on the right is used to detect the length away from the detection position of the photoelectric measuring instrument 39. After reaching the appropriate length, the motor 87 can be controlled to move, so that the motor 87 drives the sixth gear plate 86 and the fifth gear plate 85 to rotate synchronously. At this time, the sixth gear plate 86 meshes with the second gear plate 57, driving the second gear plate 57 to move and adjust. At the same time, the fifth gear plate 85 does not engage with the third gear plate 70. The second gear 57 rotates without causing the third gear 70 to rotate. The rotation of the second gear 57 drives the meshing first gear 56 to rotate. The first gear 56 drives the swing arm 55 and the adjusting docking rod 52 to rotate. The adjusting docking rod 52 is fixedly mounted with the adjusting disc 51. The adjusting disc 51 drives the first hinge shaft 46 and the spring telescopic rod 48 to move. At this time, the spring telescopic rod 48 rotates on the fixed connecting block 47 and can also extend and retract, thus allowing it to press against the heat exchanger tube 63, achieving positioning of the heat exchanger tube 63. The first guide slot frame 36 is fixedly connected... Block 47 is fixed, and the fixed mating block 49 is fixed to the bottom of the first guide slot frame 36. The first gear plate 56 is also equipped with a pressure sensor, which can sense when it has reached the limit with the heat exchanger tube 63, thereby controlling the motor 87 to stop driving. The rotation of the swing arm 55 can drive the second hinge shaft 54 ​​to follow the movement. The telescopic extrusion rod 53 is hinged on the second hinge shaft 54. The lower end of the telescopic extrusion rod 53 is hinged to the mating docking rod 50. The mating docking rod 50 is fixed to the fixed mating block 49, which allows the telescopic extrusion rod 53 to move between the mating docking rod 50 and the second hinge shaft 54, thereby performing heat exchange. The extrusion of the heat exchanger tube 63, once the tube diameter is determined, can be achieved by adjusting the installation position and angle of the first hinge shaft 46, fixed connecting block 47, spring telescopic rod 48, fixed mating block 49, and mating rod 50. This allows the spring telescopic rod 48 and the telescopic extrusion rod 53 to simultaneously contact the heat exchanger tube 63, thus providing multi-point limiting and ensuring the stability of the heat exchanger tube 63 processing. After the position is determined, the second electrically controlled telescopic rod 60 controls the adapter tooth block 58 to descend, aligning and engaging the adapter tooth block 58 with the second toothed disc 57, thereby preventing the second toothed disc 57 from moving and ensuring a stable connection.

[0056] The plasma cutting unit 72 includes a fixed support block 75, a third electrically controlled telescopic rod 76 is hinged on the fixed support block 75, a docking guide rod 77 is hinged on the third electrically controlled telescopic rod 76, the docking guide rod 77 is fixed to the rotating adjustment frame 84, a rotating control shaft 82 is fixedly connected to the rotating adjustment frame 84, a fourth gear disk 83 is fixedly connected to the side end of the rotating control shaft 82, a rotating control disk 81 is fixedly connected to the rotating control shaft 82, a plasma cutting gun holder 80 is fixedly mounted on the rotating control disk 81, a welding machine base 78 is fixedly docked on the plasma cutting gun holder 80, and the welding machine base 78 is fixed by a fixed mating plate 79, which is fixedly connected to the rotating adjustment frame 84.

[0057] The extension and retraction of the third electrically controlled telescopic rod 76 drives the welding machine base 78, the fixed mating plate 79, the plasma cutting gun base 80, the rotating control disc 81, the rotating control shaft 82, the fourth gear disc 83, and the rotating adjustment frame 84 to move, so that the fourth gear disc 83 rotates and adjusts on the docking ring frame 71. At the same time, the second electrically controlled telescopic base 73 controls the movement of the gear frame 74, so that the gear frame 74 and the fourth gear disc 83 are engaged and connected in a limited position, thereby controlling the rotation of the fourth gear disc 83.

[0058] The power switching mechanism 69 includes a third electrically controlled telescopic seat 89, which controls the extension and retraction of the connecting support rod frame 88. A motor 87 is fixedly mounted on the connecting support rod frame 88. A sixth gear plate 86 and a fifth gear plate 85 are connected to the motor 87, and the fifth gear plate 85 also rotates on the connecting support rod frame 88.

[0059] The fixed collar frame 64 is equipped with a second adapter tooth block 58 and a second second electrically controlled telescopic rod 60. The second adapter tooth block 58 can engage with the third tooth disc 70 to limit its rotation. The support platform 66 fixes the third electrically controlled telescopic seat 89. The fifth tooth disc 85 is engaged with the third tooth disc 70, and the sixth tooth disc 86 is engaged with the second tooth disc 57. The movement of the fifth tooth disc 85, the third tooth disc 70, the sixth tooth disc 86, and the second tooth disc 57 can be switched by adjusting the extension and retraction of the third electrically controlled telescopic seat 89.

[0060] Assembly component 62 includes a support base 95 and a telescopic docking rod 93 that extends to allow the connecting end seat 94 to press against the heat exchanger tube 63. Simultaneously, the air pump 90 is connected to the connecting end seat 94, enabling it to conform to the inner wall of the heat exchanger tube 63, ensuring the limiting compression between the connecting end seat 94 and the heat exchanger tube 63. This compression drives the heat exchanger tube 63 to move, bringing it onto the heat exchanger docking plate 91. The compression further ensures an interference fit between the heat exchanger docking plate 91 and the heat exchanger tube 63, achieving a limiting docking. The heat exchanger docking plate 91 is connected to a rotation control seat 92 via internal fasteners. The rotation control seat 92, when operated, drives the heat exchanger... The docking plate 91 rotates, thereby adjusting the rotation of the heat exchanger docking plate 91. This allows the heat exchanger tubes 63 to be assembled one by one according to the different slot positions on the heat exchanger docking plate 91. After assembly, the electro-hydraulic base 97 controls the heat exchanger docking plate 91 and the rotation control base 92 to descend. An external robotic arm releases the limit on the rotation control base 92 and the heat exchanger docking plate 91, simultaneously moving the heat exchanger docking plate 91 out of the assembly component 62, completing the assembly process. A connecting support plate 96 is telescopically connected to the support base 95 via the electro-hydraulic base 97. The rotation control base 92 is fixedly sleeved on the connecting support plate 96. The upper limit is connected to the heat exchanger docking plate 91, and the side end of the support base 95 is fixedly connected to the telescopic docking rod 93. An air pump 90 is installed on the photoelectric measuring instrument 39, and the side end of the air pump 90 communicates with the connecting end seat 94, which is fixed to the telescopic docking rod 93. The connecting end seat 94 has a bladder that is interference-fitted with the heat exchanger tube 63, causing the heat exchanger tube 63 to slide. The side end of the support base 95 is fixed to the conical guide frame 38. The telescopic docking rod 93 can pass through the slots on the heat exchanger docking plate 91, and a second infrared sensor is provided on the telescopic docking rod 93 for identifying the slots on the heat exchanger docking plate 91. The electro-hydraulic base 97 is connected via... The support plate 96 controls the rotation of the control seat 92 and the longitudinal adjustment of the heat exchanger docking plate 91. The fixed support block 75 is fixed to the docking ring frame 71. The rotation adjustment shaft 82 passes through the docking ring frame 71 and is fixed to the fourth gear plate 83. The third gear plate 70 rotates on the fixed sleeve frame 64 through the bearing ring 65. The side end of the second guide slot frame 67 is connected to the first guide slot frame 36. The side end of the support frame 23 is fixed to the lower end of the guide transmission seat 4. There are two guide channels 30. The guide transmission seat 4 is connected to the guide channel 30 at the rear end. The guide channels 30 at both the front and rear ends are connected to the guide docking seat 34. The guide docking seat 34 is connected to the first guide slot frame 36.

[0061] The working principle is as follows: When in use, the heat exchanger tube 63 is first stored on the storage seat 7. At this time, the guide component 5 works, and the stepper motor 16 drives the transmission disk 17 to rotate. The transmission disk 17 is fixedly provided with a first connecting rod 18 at the eccentric position. The first connecting rod 18 drives the hinged second connecting rod 19 to move, so that the second connecting rod 19 drives the hinged movable plate 11 to move. The movable plates 11 are interconnected through the connecting frame 12, and drive multiple movable plates 11 to move synchronously. When the movable plate 11 moves, the top movable plate 11 drives the sliding block 14 to move, so that the sliding block 14 slides and adjusts on the limit block 13 and the spring guide rod 15 to perform longitudinal limit, so that the movable plate 11 slides in the limit state. The movable plate 11 slides and adjusts longitudinally between the fixed plates 6, thereby pushing the heat exchanger tube 63 to be continuously transmitted to the fixed plate 6 until it reaches the guide transmission seat 4, and then it is transmitted along with the movement of the guide transmission seat 4.

[0062] Subsequently, the first electrically controlled telescopic seat 10 extends and retracts, controlling the movement of the pusher frame 8 and connecting rod 9. This causes the pusher frame 8 to push the heat exchanger tube 63, enabling it to be pushed onto the guide channels 30 at different positions. The switching of channels is controlled by the first electrically controlled telescopic rod 31. When the first electrically controlled telescopic rod 31 extends, it drives the docking guide block 28 to move, which in turn raises the plate frame 26 via the connecting diagonal rod 27. At this time, the plate frame 26 protrudes from the surface of the fixed guide frame 29, blocking the heat exchanger tube 63. The heat exchanger tube 63 is transmitted on the rear guide channel 30. When the first electrically controlled telescopic rod 31 descends, it can control the flat plate 26 to descend, so that the flat plate 26 is flush with the fixed guide frame 29. This allows the heat exchanger tube 63 to be guided to the front guide channel 30 through the flat plate 26 and the fixed guide frame 29. The heat exchanger tube 63 is then guided and transmitted through the front guide channel 30. After that, the heat exchanger tube 63 can reach the limiting support component 21 through the guide docking seat 34. The infrared sensor 25 can detect the position of the heat exchanger tube 63, thereby analyzing the location of the heat exchanger tube 63.

[0063] Different guide channels 30 reach different first guide frames 36. At this time, the control guide unit 35 works, and the lead screw 45 inside the control guide unit 35 rotates under the drive of an independent motor, causing the connecting guide frame 44 to slide on the frame 40, changing the position of the guide push rod 41, the spring telescopic sleeve 42, and the connecting wheel 43. The lower end of the connecting wheel 43 contacts the conical guide frame 38 and rotates on the conical guide frame 38. The connecting wheel 43 can push the guide push rod 41 to elastically extend and retract on the spring telescopic sleeve 42, so that the guide push rod 41 can protrude from the bottom groove of the first guide frame 36, thereby guiding the heat exchanger tube 63 to slide on the first guide frame 36. The inclined setting of the conical guide frame 38 can make the guide push rod 41... When rod 41 reaches the far right, it reaches its highest point; when it reaches the far left, it reaches its lowest point. This prevents the guide rod 41 from colliding with the heat exchanger tube 63. The photoelectric measuring instrument 39 is used for length detection of the heat exchanger tube 63. The left photoelectric measuring instrument 39 is used to detect the overall length of the heat exchanger tube 63, and the right photoelectric measuring instrument 39 is used to detect the length away from the detection position of the photoelectric measuring instrument 39. After reaching the appropriate length, the motor 87 can be controlled to move, so that the motor 87 drives the sixth gear disk 86 and the fifth gear disk 85 to rotate synchronously. At this time, the sixth gear disk 86 meshes with the second gear disk 57, driving the second gear disk 57 to move and adjust. At the same time, the fifth gear disk 85 does not contact the third gear disk 70 and will not drive the third gear disk 70. The rotation of the second gear 57 drives the first gear 56 to rotate, which in turn drives the swing arm 55 and the adjusting docking rod 52 to rotate. The adjusting docking rod 52 is fixedly mounted with the adjusting disc 51. The adjusting disc 51 drives the first hinge shaft 46 and the spring telescopic rod 48 to move. At this time, the spring telescopic rod 48 rotates on the fixed connecting block 47 and can also extend and retract, so that it can press against the heat exchanger tube 63 to achieve positioning of the heat exchanger tube 63. The first guide slot frame 36 is fixed to the fixed connecting block 47, and the fixed mating block 49 is fixed to the bottom of the first guide slot frame 36. The first gear 56 is also equipped with a pressure sensor. When it has reached the limit position with the heat exchanger tube 63, the sensor will detect the pressure sensor. The system can sense and control the motor 87 to stop driving. The rotation of the swing arm 55 can drive the second hinge shaft 54 ​​to follow the movement. A telescopic compression rod 53 is hinged on the second hinge shaft 54. The lower end of the telescopic compression rod 53 is hinged to the mating rod 50. The mating rod 50 is fixed to the fixed mating block 49, allowing the telescopic compression rod 53 to move between the mating rod 50 and the second hinge shaft 54, thereby compressing the heat exchanger tube 63. When the diameter of the heat exchanger tube 63 is determined, the installation position and angle of the first hinge shaft 46, the fixed connecting block 47, the spring telescopic rod 48, the fixed mating block 49, and the mating rod 50 can be adjusted to make the spring telescopic rod 48 and the telescopic compression rod 53 synchronously contact the heat exchanger tube 63.This multi-point limiting mechanism ensures stable performance during the processing of the heat exchanger tube 63. Once the position is determined, the second electrically controlled telescopic rod 60 controls the adapter tooth block 58 to descend, aligning and engaging it with the second toothed disc 57. This prevents the second toothed disc 57 from moving, ensuring a stable connection.

[0064] Subsequently, the heat exchanger tube 63 passes through the center of the fixed collar frame 64 and the bearing ring 65 on the second guide slot frame 67. At this time, the third electrically controlled telescopic seat 89 works, pushing the connecting support rod frame 88 to adjust and change the position of the sixth gear plate 86, the motor 87, and the fifth gear plate 85, so that the fifth gear plate 85 is aligned with the third gear plate 70, driving the third gear plate 70 to rotate on the fixed collar frame 64 through the bearing ring 65, and synchronously driving the rotating cutting mechanism 68 to rotate as a whole. The third gear plate 70 is connected to the plasma cutting unit 72 through the docking ring frame 71, and the fixed support block 75 is fixed to the docking ring frame 71. The telescopic rod 76 extends and retracts, driving the docking connecting guide rod 77 to move, so that the docking connecting guide rod 77 pushes the rotating adjustment frame 84 to move, so that the rotating adjustment frame 84 rotates on the docking ring frame 71 through the rotating control shaft 82 and the fourth gear plate 83. By changing the angles of the plasma cutting gun holder 80, the welding machine holder 78, and the fixed mating plate 79, and simultaneously sensing the distance between the plasma cutting gun holder 80 and the heat exchanger tube 63 through the distance sensor on the plasma cutting gun holder 80, the position of the plasma cutting gun inside the plasma cutting gun holder 80 can be adjusted, allowing the plasma cutting gun to be adjusted to the designated processing position. At this time, the plasma cutting gun is tilted, and with the rotation of the third toothed disc 70 and the docking ring 71, it can perform oblique cutting, making the cutting surface tilted, thereby adapting to different heat exchanger docking plates 91. After adjusting the position, the movement of the toothed frame 74 can be controlled by the second electrically controlled telescopic seat 73, so that the toothed frame 74 and the fourth toothed disc 83 are limited, and the plasma cutting gun holder 80, the rotation control disc 81, and the rotation control shaft 82 no longer rotate. The welding machine holder 78 is connected to the plasma cutting gun inside the plasma cutting gun holder 80 to realize the cutting production work.

[0065] After cutting, wait for cooling time. Cooling water can be sprayed for further cooling. During this time, the telescopic docking rod 93 extends, causing the connecting end seat 94 to press against the heat exchanger tube 63. Simultaneously, the air pump 90 is connected to the connecting end seat 94, enabling the inner wall of the heat exchanger tube 63 to be fitted, ensuring the limiting compression between the connecting end seat 94 and the heat exchanger tube 63. This compression drives the heat exchanger tube 63 to move, allowing it to reach the heat exchanger docking plate 91. The compression then creates an interference fit between the heat exchanger docking plate 91 and the heat exchanger tube 63, performing the limiting docking operation. The rotating control seat 92 is connected to the internal fasteners. The rotating control seat 92 can drive the heat exchanger docking plate 91 to rotate by running, thereby realizing the rotation adjustment of the heat exchanger docking plate 91. This allows the heat exchanger tubes 63 to be assembled one by one according to the different holes and slots on the heat exchanger docking plate 91. After the assembly is completed, the electro-hydraulic seat 97 controls the heat exchanger docking plate 91 and the rotating control seat 92 to descend. The external mechanical arm removes the limit of the rotating control seat 92 and the heat exchanger docking plate 91, and at the same time drives the heat exchanger docking plate 91 out of the assembly component 62, thus completing the assembly production work.
