Description

Technical Field

[0001] This invention relates to the field of corrugated pipe technology, and in particular to a shock-absorbing corrugated pipe for equipment and its combined welding device. Background Technology

[0002] Metal corrugated pipes are pipes with a regular wave-like shape. The inlet and outlet positions of central air conditioning pumps, fire pumps, and domestic water supply pumps experience significant vibrations. Therefore, vibration-damping corrugated pipes are needed to connect at the inlet and outlet positions of these pumps to reduce vibration and absorb pipeline noise. Vibration-damping corrugated pipes consist of two flanges and a corrugated pipe in the middle. They connect the pipeline system through expansion and contraction and absorb the vibration of the pipeline system by converting the vibration into deformation energy, thereby achieving the effect of vibration reduction. During production, the flanges and the corrugated pipe in the middle are usually connected by welding.

[0003] Generally, when assembling and welding pipes and flanges, manual operation is required to spun the pipes and flanges together before welding them using welding equipment. When welding heavy corrugated pipes for some equipment, the heavy pipes and flanges need to be manually moved onto the equipment. After the pipes and flanges are spun and initially positioned, they still need to be manually moved onto the welding equipment for loading and welding. During the overall splicing and welding process, and after welding, the welded corrugated pipes need to be manually moved and unloaded. Manual handling of loading and unloading is very inconvenient. Furthermore, the assembly and welding of the pipes and flanges requires assembly and welding operations on two separate machines, making the overall assembly process quite complicated. After welding the pipes and flanges, a grinder is needed to grind the weld seams, making the overall operation inconvenient and requiring further improvement in processing efficiency. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention, by incorporating a locking block and a locking groove, allows for the initial positioning of the pipe body with the upper and lower flanges during assembly. The locking block is positioned within the locking groove by sliding into it and then rotating. After positioning, the pipe body is further secured to the upper and lower flanges by welding. This eliminates the need for spinning equipment to fix the upper and lower flanges to the pipe body during assembly, making the operation convenient and improving assembly efficiency.

[0018] This invention, by incorporating a feeding mechanism, a synchronous clamping mechanism, and a pushing mechanism, allows for automatic alignment of the pipe body, upper flange, and lower flange during the feeding and processing. After alignment, the three components can be quickly and initially joined by rotating them after relative docking. Before welding the corrugated pipe, there is no need to use equipment to spin-press the corrugated pipe components, reducing processing steps and improving processing efficiency. Furthermore, after the pipe body, upper flange, and lower flange are aligned, the assembled shock-absorbing pipe body can be welded and ground using a welding torch and a grinder, eliminating the need to transport the shock-absorbing pipe body elsewhere for welding and grinding, thus reducing labor costs. Finally, after processing, the alignment mechanism can automatically unload the processed shock-absorbing pipe body, effectively improving overall processing efficiency.

[0019] This invention features a positioning mechanism that uses four correction blocks to push the upper flange towards the center for positioning. The detection seat and the first distance sensor work together with the second gear to rotate and mesh with the base, driving the workpiece on the positioning platform to rotate synchronously for detecting the positioning blocks. Simultaneously, the lifting and lowering of the positioning platform enables the loading and unloading of the pipe body, upper flange, and lower flange.

[0020] This invention features a feeding mechanism and a chain. The four outer retaining rings can move towards the center to clamp the upper flange. Simultaneously, the outer retaining rings can be locked and unlocked between the positioning component, the chain, and the positioning plate to achieve positioning switching when the outer retaining rings move to the highest point. This prevents the outer retaining rings from affecting processing by moving with the chain later. Furthermore, the automatic feeding of the upper flange, lower flange, and pipe body can be achieved through the cooperation of the chain, the alignment table, and the outer retaining rings, and the alignment mechanism can be used for alignment, thus improving processing efficiency.

[0021] This invention features a synchronous clamping mechanism. During loading, protruding clamping blocks clamp and position the tube. Simultaneously, a second distance sensor identifies the trough position of the tube and ensures the protruding clamping blocks clamp at the trough position, improving clamping stability. Furthermore, the rotation of the fourth gear meshes with the second gear ring, driving the synchronous ring to adjust the tube angle and facilitate subsequent welding and grinding operations. The cooperation of a laser emitter and receiver ensures uniform clamping position of the tube. Finally, an alignment detection block, in conjunction with a contact sensor, identifies the position of the locking groove on the tube, ensuring accurate alignment of the tube, upper flange, and lower flange in the later stages.

[0022] This invention, by incorporating a chain, welding torch, and grinding machine, allows for the locking of the chain with the welding torch and grinding machine after the corrugated pipe is assembled. This locks the chain in place to adjust the position of the welding torch and grinding machine, enabling welding and grinding operations on the corrugated pipe. After welding and grinding are completed, the chain can be unlocked from the welding torch and grinding machine and then locked to the outer retaining ring for the next processing and loading operation. The chain's position adjustment is achieved by switching between the unlocking and locking states with the outer retaining ring, welding torch, and grinding machine, thus improving the performance.

[0023] This invention features a lower pressure seat. During the loading of the upper flange, the lower pressure seat extends into the interior of the upper flange and uses side clamping blocks to internally clamp the upper flange before pushing it down, completing the loading and alignment operation of the upper flange. When welding is required between the upper flange, lower flange, and pipe body later, the lower pressure seat can extend into the interior of the upper flange to press and position its inner wall. By unlocking the connecting column and mounting sleeve, it can rotate synchronously with the assembled shock-absorbing pipe body assembly, thereby clamping and positioning the assembled upper flange, pipe body, and lower flange from above, ensuring stability during welding and grinding.

[0041] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0042] Reference Figure 1-2A vibration-damping corrugated pipe for equipment includes a vibration-damping pipe assembly 1. The vibration-damping pipe assembly 1 includes a pipe body 11, an upper flange 12, and a lower flange 13. Both ends of the pipe body 11 are open. The upper flange 12 is located at the top of the pipe body 11, and the lower flange 13 is located at the bottom of the pipe body 11. The vibration-damping pipe assembly 1 also includes locking grooves 14, anti-detachment grooves 15, and locking blocks 16. Four locking grooves 14 are evenly distributed on the outer circular wall surface of the pipe body 11. The locking grooves 14 are L-shaped grooves. The anti-detachment grooves 15 are located on both sides of the inner wall of the locking grooves 14. The locking blocks 16 are symmetrically fixedly installed on both sides of the inner wall of the upper flange 12 and the lower flange 13. The locking blocks 16 are movably connected to the locking grooves 14 and are composed of an arc-shaped block and two inclined elastic blocks. The elastic block on the locking block 16 can be locked into the anti-dislodgement groove 15. By setting the locking block 16 and opening the locking groove 14, when assembling the shock-absorbing tube assembly 1 as a whole, the upper flange 12 and the lower flange 13 can be aligned with the tube body 11. During alignment, the locking block 16 can be locked into the locking groove 14. After the locking block 16 slides into the locking groove 14 and rotates, the tube body 11 and the upper flange 12 and the lower flange 13 are initially positioned. After positioning, the tube body 11 and the upper flange 12 and the lower flange 13 can be fixed a second time by welding. When assembling the tube body 11, the upper flange 12 and the lower flange 13, there is no need to use spinning equipment to fix the upper flange 12 and the lower flange 13 to the tube body 11. The operation is convenient and the assembly efficiency is improved.

[0043] Reference Figure 3-16A combined welding device for vibration-damping corrugated pipes for equipment includes an outer frame 2. A positioning mechanism 3 is installed at the bottom of the outer frame 2. During assembly, the positioning mechanism 3 can perform alignment and straightening operations on the pipe body 11, upper flange 12, and lower flange 13 during loading, as well as subsequent unloading operations. A loading mechanism 4 is installed on the outer frame 2 to load the upper flange 12. A synchronous clamping mechanism 5 is installed on the outer frame 2 to clamp the pipe body 11. Later, it can perform synchronous driving operations for the rotational splicing of the upper flange 12, lower flange 13, and pipe body 11. A pushing mechanism 6 is installed on the outer frame 2 to push the upper flange 12 downwards for loading and to facilitate subsequent grinding. The outer frame 2 has a clamping mechanism to ensure grinding stability. Rotary tables 24 are installed on opposite sides of the inner wall of the outer frame 2. A welding torch 25 is rotatably mounted on one of the rotating tables 24, and a grinding machine 26 is rotatably mounted on the other. The welding torch 25 and grinding machine 26 allow for welding and grinding operations at the connection points of the pipe body 11, upper flange 12, and lower flange 13. An intercepting box 29 is slidably mounted on the outer frame 2 via an electric slide rail. The intercepting box 29 collects welding slag and debris generated during subsequent grinding. Two chains 21 are movably mounted on both sides of the outer frame 2. The rotation of the chains 21 drives the feeding mechanism 4, welding torch 25, and grinding machine 26 to adjust their positions. The outer frame 2 also has rotating... Two first gears 22 mesh with a chain 21. The first gears 22 are driven by a servo motor, and their rotation drives the chain 21 to rotate cyclically. With the chain 21, first gears 22, alignment mechanism 3, and feeding mechanism 4, during processing, the operator can directly place the pipe body 11, upper flange 12, and lower flange 13 onto the alignment mechanism 3. The alignment mechanism 3 then automatically performs alignment detection on the pipe body 11, upper flange 12, and lower flange 13, subsequently cooperating with the chain 21 and first gears 22 to achieve automatic feeding. Feeding is fast and convenient, eliminating the need for manual alignment and improving overall processing efficiency. With the feeding mechanism 4, synchronous clamping mechanism 5, and pushing mechanism 6, the pipe body 11, upper flange 12, and lower flange 13 can be automatically fed into the chain. When the upper flange 12 and lower flange 13 are being processed, the pipe body 11, upper flange 12 and lower flange 13 can be automatically aligned. After alignment, the three can be rotated after being connected to each other to achieve a preliminary and rapid splicing. Before welding the corrugated pipe, there is no need to use equipment to spin the corrugated pipe components, which reduces processing steps and improves processing efficiency. At the same time, after the pipe body 11, upper flange 12 and lower flange 13 are aligned, the assembled shock-absorbing pipe assembly 1 can be welded and ground. There is no need to move the shock-absorbing pipe assembly 1 to another place for welding and grinding, which reduces labor costs. After processing, the alignment mechanism 3 can be used to automatically unload the processed shock-absorbing pipe assembly 1, which effectively improves the overall processing efficiency.

[0044] As an optimized solution for the combined welding device of the vibration damping bellows for equipment according to the present invention, the alignment mechanism 3 includes an alignment platform 31, a correction block 32, a first gear ring 33, a second gear 34, a base 35, a rack 36, and a third gear 37. The base 35 is rotatably mounted at the bottom loading position of the outer frame 2. The first gear ring 33 is fixedly mounted on the outer wall of the base 35. The second gear 34, which meshes with the base 35, is rotatably mounted on the outer frame 2. The second gear 34 is driven by a servo motor, which is electrically connected to a peripheral controller (CPM2C). The rotation of the second gear 34 can drive the base 35. 5. The alignment platform 31 is movably mounted on the top of the base platform 35, and is driven by a hydraulic telescopic rod that is electrically connected to an external controller. The alignment platform 31 can be raised and lowered inside the outer frame 2. Four correction blocks 32 are slidably mounted on the four sides of the top of the alignment platform 31. The correction blocks 32 are trapezoidal blocks and can perform correction operations on the pipe body 11, the upper flange 12, and the lower flange 13. Two third gears 37 are rotatably mounted on the upper and lower sides inside the alignment platform 31. The two third gears 37 are driven by a servo motor, and the output shaft of the servo motor is connected to the two third gears. Wheel 37 is fixedly connected, servo motor is electrically connected to peripheral controller, four racks 36 for connecting correction blocks 32 are slidably installed inside the alignment platform 31, the four racks 36 are arranged on the upper and lower sides, and the two racks 36 in each group mesh with the third gear 37. When the third gear 37 rotates, it can drive the two racks 36 to move towards or away from the center position synchronously. A detection seat 28 is movably installed at the loading position inside the outer frame 2. The detection seat 28 is driven by a hydraulic telescopic rod and is located on the upper side of the alignment platform 31. The first distance sensor 281 (KTR5-150) is fixedly installed. At the bottom of the detection seat 28, the first distance sensor 281 is electrically connected to the peripheral controller. With the above structure, the third gear 37 meshes with the rack 36 to drive the four racks 36 to push the four correction blocks 32 to the middle position to perform the correction operation on the upper flange 12. The detection seat 28 and the first distance sensor 281 cooperate with the second gear 34 to rotate and mesh with the base 35 to drive the workpiece on the correction platform 31 to rotate synchronously to perform the detection operation on the clamping block 16. At the same time, the loading and unloading operations of the pipe body 11, the upper flange 12 and the lower flange 13 can be realized by raising and lowering the correction platform 31.

[0045] As an optimized solution for the combined welding device of the vibration-damping corrugated pipe for equipment according to the present invention, the feeding mechanism 4 includes an outer retaining ring 41 and positioning blocks 42. The outer retaining ring 41 is movably installed between two chains 21 and is interconnected with the chains 21 through positioning components. Three positioning blocks 42 are movably installed inside the outer retaining ring 41 and are driven by a hydraulic telescopic rod. The hydraulic telescopic rod is electrically connected to an external controller. The side wall of the positioning block 42 near the center of the outer retaining ring 41 is lined with rubber. The upper sides of the inner side of the outer frame 2 are positioned... Two symmetrically fixed positioning horizontal plates 23 are installed. The positioning horizontal plates 23 are also connected to the outer retaining rings 41 through positioning components. When the outer retaining rings 41 move to the upper position inside the outer frame 2, they can be locked to the two positioning horizontal plates 23 through the positioning components. With the above structure, the four outer retaining rings 41 can move to the middle position to achieve the clamping operation of the upper flange 12. At the same time, the outer retaining rings 41 can be locked and unlocked between the positioning components, the chain 21 and the positioning horizontal plates 23 to achieve the positioning switch of the outer retaining rings 41 moving to the highest point.

[0046] As an optimized solution for the combined welding device of the vibration damping corrugated pipe for equipment according to the present invention, the positioning component includes locking shafts 43 and locking sleeves 44. The four locking shafts 43 are respectively movably installed on both sides of the outer wall of the outer retaining ring 41 and on the side where the two positioning horizontal plates 23 are close to each other. The locking shafts 43 are driven by a hydraulic telescopic rod, which is electrically connected to an external controller. The four locking sleeves 44 are respectively set on one side of the telescopic end of the four locking shafts 43. Two locking sleeves 44 are fixedly installed on the side where the two chains 21 are close to each other, and the other two locking sleeves 44 are fixedly installed on the side where the two positioning horizontal plates 23 are close to each other. With the above structure, the locking and unlocking operation between the outer retaining ring 41 and the chain 21 and the positioning horizontal plate 23 can be realized by the locking shaft 43 being inserted into the locking sleeve 44.

[0047] As an optimized solution for the combined welding device of the vibration-damping corrugated pipe for equipment according to the present invention, the synchronous clamping mechanism 5 includes a synchronous ring 51, protruding clamping blocks 511, and a second distance sensor 512. The synchronous ring 51 is rotatably installed inside the outer frame 2 and is located near the middle position inside the outer frame 2. The three protruding clamping blocks 511 are movably installed inside the synchronous ring 51. The side wall of the protruding clamping block 511 near the center of the synchronous ring 51 is arc-shaped. The protruding clamping block 511 is driven by a hydraulic telescopic rod, which is electrically connected to an external controller. The second distance sensor 512 (KTR5-150) is fixedly installed on one of the protruding clamping blocks 511 and is electrically connected to the external controller. With the above structure, after the pipe body 11 enters the synchronous ring 51, the four protruding clamping blocks 511 can perform clamping operations on the pipe body 11. During clamping, the second distance sensor 512 can identify the trough position of the pipe body 11, ensuring that the protruding clamping blocks 511 can clamp the trough position of the pipe body 11.

[0048] As an optimized solution for the combined welding device of the vibration-damping bellows for equipment according to the present invention, the synchronous clamping mechanism 5 further includes a second gear ring 513, a fourth gear 514, a first movable seat 52, a laser emitter 521, an alignment seat 522, an alignment detection block 523, a contact sensor 524, a contact pressure shaft 525, a second spring 526, a second movable seat 53, and a laser receiver 531. The second gear ring 513 is fixedly installed on the outer wall of the synchronous ring 51, and the fourth gear 514, which meshes with the second gear ring 513, is rotatably installed on the outer frame 2. The fourth gear 514 is driven by a servo motor, and the rotation of the fourth gear 514 can drive the second gear ring 513 to drive the synchronous ring 51 to rotate synchronously. Two first movable seats 52 are movably mounted on one side of the outside of the synchronization ring 51. The two first movable seats 52 are driven by a bidirectional hydraulic telescopic rod, which is electrically connected to an external controller. A fixing ring is fixedly installed between the two first movable seats 52 and is fixedly connected to the outer frame 2. Two laser emitters 521 (Q2XAPR-Q3) are fixedly mounted on the side of the two first movable seats 52 that is far from each other.

On one side of block 523 extending into the groove, contact pressure shaft 525 is sleeved with second spring 526, and contact pressure shaft 525 can contact contact sensor 524. With the above structure, the rotation of fourth gear 514 can mesh with second gear ring 513 to drive synchronous rotation of synchronous ring 51 to realize the adjustment of the angle of tube body 11 and subsequent welding and grinding drive operation. At the same time, the cooperation of laser emitter 521 and laser receiver 531 ensures that the clamping position of tube body 11 is uniform. The alignment detection block 523 cooperates with contact sensor 524 to realize the identification operation of the position of the locking groove 14 on tube body 11, ensuring accurate alignment of tube body 11, upper flange 12 and lower flange 13 in the later stage.

[0049] As an optimized solution for the combined welding device of the vibration-damping corrugated pipe for equipment according to the present invention, the pushing mechanism 6 includes a lower pressure seat 61, a side clamping block 62, a connecting column 63, and a mounting sleeve 64. The lower pressure seat 61 is movably installed at the top of the inner part of the outer frame 2.

The mounting sleeve 64 is fixedly connected to the telescopic end of the hydraulic telescopic rod. The connecting column 63, used to connect the mounting sleeve 64, is fixedly installed on the top of the lower pressure seat 61. The connecting column 63 and the mounting sleeve 64 are connected... The four side clamping blocks 62 are movably installed on the four sides of the outer wall of the lower pressure seat 61. The side clamping blocks 62 are driven by hydraulic telescopic rods, which are electrically connected to an external controller. With the above structure, the four side clamping blocks 62 can move to clamp and position the upper flange 12 and push the upper flange 12 down to the pipe body 11 for alignment and splicing. The connecting column 63 and the mounting sleeve 64 can be directly locked and unlocked to ensure that the lower pressure seat 61 can rotate freely while clamping the upper flange 12 during subsequent welding and grinding.

[0050] As an optimized solution for the combined welding device of the vibration-damping corrugated pipe for equipment according to the present invention, the pushing mechanism 6 further includes a fifth gear 65, a linkage block 66, and a third distance sensor 67. The fifth gear 65 is fixedly installed on one end of the connecting column 63 extending into the mounting sleeve 64. The mounting sleeve 64 has a rotating groove for connecting the connecting column 63. The cross-section of the rotating groove is T-shaped. The fifth gear 65 is movably installed on one side inside the rotating groove. The fifth gear 65 is a block with a trapezoidal cross-section. The linkage block 66 can be engaged between two adjacent fifth gears 65. The linkage block 66 is driven by an electric telescopic rod. The electric telescopic rod is electrically connected to the external controller. The third distance sensor 67 is fixedly installed on the linkage block 66 and is electrically connected to the external controller. The third distance sensor 67 can sense the gap between the two fifth gears 65 and drive the linkage block 66 to engage between the two adjacent fifth gears 65 through the electric telescopic rod. With the above structure, after the third distance sensor 67 identifies the gap between the two fifth gears 65, the linkage block 66 can be pushed into the gap between the two fifth gears 65 to realize the locking and unlocking operation between the connecting column 63 and the mounting sleeve 64.

[0051] As an optimized solution for the combined welding device of the vibration-damping corrugated pipe for equipment according to the present invention, the rotary table 24 is fixed to the outer frame 2 and the chain 21 respectively by fixing components. The fixing components include a first locking seat 241, a second locking seat 242, and connecting blocks 243. The first locking seat 241 is fixedly installed on the outer frame 2, the second locking seat 242 is fixedly installed on the chain 21, and two connecting blocks 243 for connecting the first locking seat 241 and the second locking seat 242 are movably installed on both sides of the rotary table 24. 243 is driven by a hydraulic telescopic rod, which is electrically connected to an external controller. Both the first locking seat 241 and the second locking seat 242 have positioning ports for connecting the connecting block 243, and the positioning ports are engaged with the connecting block 243. With the above structure, the rotating table 24 can be locked to the first locking seat 241 and the second locking seat 242 by pushing the connecting block 243 into them. When unlocking, the connecting block 243 disengages from the first locking seat 241 and the second locking seat 242.

[0052] As an optimized technical solution for the combined welding device of the vibration-damping corrugated pipe for equipment according to the present invention, a trigger assembly is provided between the outer frame 2 and the chain 21. The trigger assembly includes an extension seat 27, a first spring 271, a trigger switch 272, a trigger shaft 273, and a pressing plate 274. The pressing plate 274 is fixedly installed on the chain 21. The extension seat 27 is fixedly installed inside the outer frame 2 near the upper end. The extension seat 27 is an arc-shaped block. The trigger shaft 273 is movably installed inside the extension seat 27. The downward-extending side of the trigger shaft 273 is arc-shaped. The pressing plate 274 can press the trigger shaft 273 upward. The first spring 271, used to connect the trigger shaft 273, is fixedly installed inside the extension seat 27. The trigger shaft 273 is sleeved with the first spring 271. The two ends of the first spring 271 are fixedly connected to the trigger shaft 273 and the extension seat 27, respectively. Mounting rings for connecting the first spring 271 are fixedly installed on both the extension seat 27 and the trigger shaft 273. The trigger switch 272 is movably installed inside the extension seat 27 and is driven by an electric telescopic rod. The trigger switch 272 is electrically connected to an external controller. With this structure, when the chain 21 moves the pressing plate 274 to its highest position, the pressing plate 274 can press the trigger shaft 273 to trigger the trigger switch 272 for subsequent operations. Simultaneously, during welding and grinding, the trigger switch 272 moves upwards. During the back-and-forth movement of the pressing plate 274, the pressing plate 274 will not press the trigger shaft 273 to trigger the trigger switch 272.

[0053] When using this invention, before welding the corrugated pipe, the pipe body 11, upper flange 12 and lower flange 13 to be assembled and welded are placed at the bottom of the outer frame 2. At the same time, before welding, the operator inputs the length, inner and outer diameter and crest height of the corrugated pipes of the same batch and specifications into the external control system. The pipe body 11, upper flange 12 and lower flange 13 are then ready.

[0054] The upper flange 12 is placed on the alignment platform 31. An external servo motor drives two third gears 37 to rotate. These third gears 37 mesh with racks 36, driving four racks 36 to push four correction blocks 32 towards the center position to perform alignment of the upper flange 12, ensuring that the center of the upper flange 12 is aligned with the center of the alignment platform 31. After alignment, according to the pre-input bellows dimensions, the detection seat 28 is pushed out to the corresponding inner wall edge of the upper flange 12. The first distance sensor 281 activates to sense distance changes. Simultaneously, the external servo motor... The servo motor starts, driving the second gear 34 to rotate and, through meshing with the base platform 35, synchronously rotating the upper flange 12 on the alignment platform 31. Simultaneously, the first distance sensor 281 detects the position of the locking block 16 inside the upper flange 12 by sensing distance changes. When the first distance sensor 281 detects the locking block 16, the second gear 34 and the base platform 35 stop rotating, the locking block 16 on the upper flange 12 is aligned, and the hydraulic telescopic rod drives the alignment platform 31 upwards into the outer retaining ring 41. (The last sentence appears to be incomplete and possibly refers to a different process.) The correction block 32 moves to the four sides away from the upper flange 12. Simultaneously, the four positioning blocks 42 move to the center position and contact and press against the outer wall of the upper flange 12 to clamp the upper flange 12. After the upper flange 12 is clamped and positioned inside the outer retaining ring 41, the correction platform 31 resets, the first gear 22 rotates and drives the outer retaining ring 41 to rise through meshing with the chain 21 (during the rising of the outer retaining ring 41, the operator simultaneously performs the loading operation of the pipe body 11). When the outer retaining ring 41 rises to the highest point between the two chains 21, it squeezes... Plate 274 presses upward against trigger shaft 273, trigger shaft 273 comes into contact with trigger switch 272, trigger switch 272 is triggered, outer retaining ring 41 is unlocked from chain 21, outer retaining ring 41 is locked to two positioning horizontal plates 23. Unlocking and locking here are achieved by hydraulic telescopic rod driving locking shaft 43 to extend or disengage from inside locking sleeve 44. After outer retaining ring 41 is locked to positioning horizontal plate 23, trigger switch 272 moves upward to ensure that pressing plate 274 will not trigger trigger switch 272 through trigger shaft 273 during subsequent chain 21 rotation.

[0055] During the upward movement of the outer ring 41, the operator simultaneously feeds the tube 11. After the tube 11 is placed on the alignment platform 31, the above steps are repeated to perform the center alignment operation of the tube 11. After the center of the tube 11 is aligned with the center of the alignment platform 31, the hydraulic telescopic rod drives the alignment platform 31 to rise until the tube 11 enters the interior of the synchronization ring 51. When the tube 11 is pushed upward, according to the pre-input size specifications of the corrugated pipe, the two first movable seats 52 and the two second movable seats 53 extend upward and downward to the sides according to the length of the corrugated pipe. When the laser emitted by the upper laser emitter 521 is no longer received by the laser receiver 531, and the laser emitted by the lower laser emitter 521 is received by the laser receiver 531, it indicates that the upper end of the tube 11 has reached the upper laser. At the transmitter 521, the lower end of the tube 11 reaches the lower laser transmitter 521. As the tube 11 is pushed into the interior of the synchronization ring 51, the second distance sensor 512 starts to sense the change in distance to detect the trough position outside the tube 11. When the laser emitted by the upper laser transmitter 521 is no longer received by the laser receiver 531, and the laser emitted by the lower laser transmitter 521 is received by the laser receiver 531, and the second distance sensor 512 senses that this is the trough of the tube 11, the alignment platform 31 stops pushing upward. If it is not the trough, it continues to push upward to the trough. The four protruding clamping blocks 511 move to the middle position to the trough of the tube 11 and press to clamp the tube 11. After the tube 11 is clamped, the operator can perform the loading operation of the lower flange 13.

[0056] After the tube body 11 is clamped, the alignment seat 522 is extended outward according to the pre-input outer diameter of the bellows. When the alignment seat 522 extends to the tube body 11, if the alignment detection block 523 is squeezed into the alignment seat 522, and the contact pressure shaft 525 and the contact sensor 524 come into contact, then this is not the location of the locking slot 14. In this case, the external servo motor drives the fourth gear 514 to rotate and drives the synchronous ring 51 to rotate by meshing with the second gear ring 513 until the alignment detection block 523 is no longer squeezed. Then the contact pressure shaft 525 no longer contacts the contact sensor. When the sensors 524 come into contact with each other, it indicates that this is the location of the locking groove 14, and the alignment of the locking groove 14 is complete. At this time, the locking groove 14 on the pipe body 11 and the locking block 16 on the upper flange 12 are on the same vertical line. The alignment of the locking groove 14 and the locking block 16 is complete. The hydraulic telescopic rod is activated to drive the lower pressure seat 61 to push down to the inside of the upper flange 12. The four side clamping blocks 62 are pushed out to the four sides to abut against the inner wall of the upper flange 12 to clamp the upper flange 12. After the lower pressure seat 61 clamps the upper flange 12, the connecting column 63 continues to push down to the locking block on the upper flange 12. The positioning block 16 is pushed into the locking groove 14 on the pipe body 11. During the downward pushing of the lower pressure seat 61, the operator places the lower flange 13 on the alignment platform 31 and performs center alignment and positioning operation of the locking block 16 on the lower flange 13. After the positioning block 16 is aligned, the alignment platform 31 pushes up to push the lower flange 13 to the bottom pipe end position of the pipe body 11 inside the synchronization ring 51. The locking grooves 14 at both ends of the pipe body 11 are aligned with the locking blocks 16 on the upper flange 12 and the lower flange 13. The lower pressure seat 61 then pushes the upper flange downward. Inside 12, the side clamping block 62 clamps the upper flange 12. Then, the electric telescopic rod drives the linkage block 66 to disengage between the two fifth gears 65. The connecting column 63 and the mounting sleeve 64 are unlocked. After unlocking, the fourth gear 514 rotates and drives the tube body 11 in the synchronous ring 51 to rotate through meshing with the second gear ring 513. The upper flange 12 rotates into place, and the locking block 16 is locked into the anti-disengagement groove 15. The initial positioning of the tube body 11 with the upper flange 12 and the lower flange 13 is completed. The welding operation of the tube body 11 with the upper flange 12 and the lower flange 13 is started.

[0057] When the welding torch 25 rotates to its final position, it unlocks from the first locking seat 241 on the outer frame 2 and locks to the second locking seat 242 on the chain 21. The unlocking and locking of the second locking seat 242 and the rotary table 24 are achieved by the connecting block 243 engaging and disengaging from the first locking seat 241 and the second locking seat 242. After the welding torch 25 is locked to the chain 21, the first gear 22 rotates and, through meshing with the chain 21, drives the welding torch 25 to move and adjust to the position where the pipe body 11 connects to the upper flange 12. The fourth gear 514 rotates to drive the synchronous ring 51 to rotate, and the pipe body 11 and the upper flange 12 rotate synchronously. The welding torch 25 welds the connection between the pipe body 11 and the upper flange 12. During the welding process, the interception box 29 slides to the position directly below the welding area to collect the welding slag. After the connection between the pipe body 11 and the upper flange 12 is welded, the welding torch 25 slides and adjusts to the position where the pipe body 11 and the lower flange 13 are connected to weld. After the welding is completed, the welding of the pipe body 11, the upper flange 12 and the lower flange 13 is completed.

[0058] Chain 21 drives welding torch 25 to slide and reset. Rotary table 24 on welding torch 25 unlocks from second locking seat 242 and locks with first locking seat 241. Then, rotary table 24 on grinding machine 26 unlocks from first locking seat 241 and locks with second locking seat 242. Chain 21 rotates to drive grinding machine 26 to adjust its position. Grinding machine 26 slides to the welding position of pipe body 11 and upper flange 12 for grinding. After grinding, grinding machine 26 slides to the welding position of pipe body 11 and lower flange 13 for grinding. After grinding, the overall welding assembly of pipe body 11, upper flange 12 and lower flange 13 is completed. After assembly, interceptor box 29 slides and resets. Alignment platform 31 is pushed up to the position of upper flange 12. Side clamping block 62 and protruding clamping block 511 move and reset. Four correction blocks 32 move to the middle position to clamp the pipe body 11 and then descend to the loading position. The operator takes it out, and the overall processing is completed.

[0059] During material feeding, chain 21 drives grinding machine 26 to reset. During reset, trigger switch 272 pushes downward, chain 21 drives extrusion plate 274 to move to the highest point to extrude trigger shaft 273. Trigger shaft 273 extrudes trigger switch 272, triggering outer retaining ring 41 to unlock from positioning plate 23 and lock with chain 21. Chain 21 rotates to reset outer retaining ring 41, and then the next processing operation can be performed.
