[0002] During the processing of tobacco pipes, it is necessary to assemble pipes of different lengths, with one end of the long pipe assembled with other pipes, and the other end sealed by welding a plug, and holes are drilled on the surface of the sealed section to achieve exhaust.

[0003] Chinese Patent Application CN202220363742.0 discloses a pipe laser welding machine, including a frame. A welding frame is fixedly connected to the middle position of the upper surface of the frame. Fixing mechanisms are arranged on both sides of the welding frame. A through circular cavity is opened in the middle position of the welding frame. A bearing is arranged inside the circular cavity. A rotating sleeve is arranged on one side of the bearing. The rotating sleeve is rotatably connected to the welding frame through the bearing. A rotating mechanism is arranged between the outer surface of the rotating sleeve and one side of the welding frame.

[0004] The following problems exist in the above patent and the prior art:

[0005] Existing pipes are usually made of relatively thin coils. Therefore, during the transportation of the pipes or the process of clamping and transferring, the end to be welded with the plug will be bent and uneven due to bumps. When the plug is used to seal and weld the pipe fitting, the width of the metal molten pool cannot adhere well to the plug and the pipe, resulting in low connection strength of the welding head. In addition, after welding, the other end of the pipe needs to be flared, which requires repositioning and flaring, resulting in cumbersome processes. Summary of the Invention

[0038] Beneficial effects of the present invention:

[0039] When the lifting plate is lifted, the plurality of clamping column heads on the side of the blocking section will move to the surface of the blocking section under the lifting of the plurality of vertical plates, and then the plurality of clamping column heads will be in contact with the surface of the blocking section under the contact of the plurality of clamping column heads with the surface of the blocking section.

[0040] Second, move the displacement table downward again, so that the displacement table drives the expansion head to approach the inside of the expansion section, and finally insert the expansion head into the inside of the expansion section, so that the width profile of the expansion head squeezes the expansion section to expand outward, so that the expansion head pushes the expansion section and the sleeve module to contact, so that the expansion section is closed and squeezed by the expansion head and the sleeve module to form an expansion, thereby increasing the diameter of the expansion section opening, which is convenient for subsequent assembly.

[0041] 3. Start the processing power source, and make it drive the circular turntable to rotate. The rotation of the circular turntable will drive the movable disk at its bottom to rotate accordingly. Under the action of the grease pre-applied to the opposite surfaces of the expansion head and the sleeve module, the expansion head and the sleeve module rotate relative to the clamped smoke tube fitting following the circular turntable. During the lubricating rotation, the expansion head and the sleeve module rotate and smooth the expanded tube section, thereby avoiding excessive stress on a certain part of the expanded tube section, thereby reducing local deformation or irregular expansion of the smoke tube fitting during the expansion process, thereby making the expansion more uniform.

[0042] Fourth, the rotation of the movable disk will drive the docking joint inserted into it to rotate through the docking interface, and the rotation of the docking joint is driven by the vertical plate, so that the clamping plate rotates relative to the bearing plate through the rotating member 2, and the ring plate connected to the vertical plate through the extension plate rotates relative to the output shaft of the lifting member 1, so that when multiple clamping plates follow the rotation of the movable disk, the multiple clamping column heads on the top will roll on the surface of the plugging section during the rotation of the clamping plate, so that the clamping column heads squeeze the inner wall of the plugging section to fit the surface of the pipe plug during rolling, so that the gap between the two is reduced, which helps to improve the sealing performance between the two and ensure that there will be no leakage at the joint after welding. The unevenness of the opening of the plugging section and its surface will also be relatively rolled flat, thereby reducing the gap and unevenness during welding, and helping to stabilize the metal molten pool during welding, reduce the occurrence of welding defects such as pores and cracks, and improve the strength and quality of the welded joint.

[0043] 5. After the circular turntable drives the movable disk to rotate for a preset time, the sealing section is smoothly attached to the surface of the pipe plug, and then the laser welding head is started to rotate with the circular turntable, so that the laser welding head performs rotational welding on the connection between the top of the pipe plug and the inner wall of the sealing section, thereby reducing the external welding of the pipe plug and the sealing section in the prior art through internal welding, so that there is a gap directly between the top of the pipe plug and the inner wall of the sealing section. Therefore, under the frequent flushing of flue gas, part of the flue gas that has not been discharged through the drilling section will rush into the gap between the pipe plug and the sealing section, aggravating the connection fatigue degree of the pipe plug and the sealing section. The internal welding of the sealing section and the pipe plug reduces the contact of the gap between the sealing section and the pipe plug with respect to the flue gas, and the gap between the sealing section and the pipe plug is rolled and compressed during the rotation of the clamping column head, thereby further improving the connection strength between the pipe plug and the sealing section.

[0044] 6. In the process of rolling the clamping column head relative to the blocking section, the middle part of the smoke tube, i.e. the clamping section, is clamped by the clamping claws, and the top of the smoke tube is lubricated and clamped by the expansion head and the sleeve module, so that the smoke tube is fixed in multiple places, and the clamping column head rolls the blocking section and the pipe plug relative to each other, thereby reducing the axial runout of the smoke tube when the clamping column head is leveling the surface of the blocking section, thereby facilitating the laser welding head to weld the blocking section and the pipe plug more stably.

An installation column 3093 is fixedly connected to the bottom of the swaging head 3082. A laser welding head 3094 is fixedly connected to the bottom of the installation column 3093. Cavities for power supply control wiring of the laser welding head 3094 are arranged inside the installation column 3093 and the swaging head 3082.

[0086] The expansion head 3082, the mounting post 3093, and the closed sleeve module 3091 are coaxial.

[0087] Operation process:

[0088] Suspend the tobacco pipe fitting 4 between the two jaws 2042 at the front end of the clamping unit 2 through a long pipe feeder or manually or by a manipulator. Start the clamping power source 2041, and the clamping power source 2041 drives the driven member 20421 on the side of any jaw 2042 to move inside the clamping frame 204 through the driving member 20411. The jaw 2042 drives the driven member 20421 on the side of the other jaw 2042 to rotate through the driven member 20421, so that the front section of the jaw 2042 clamps the surface of the clamping section 401 of the tobacco pipe fitting 4. Start the transmission power source 102, and the transmission power source 102 drives the rotating shaft 103 and the transmission gear 104 to rotate through the belt, and the transmission gear 104 drives the transmission chain 105 to rotate. Thus, when the transmission chain 105 rotates, it will drive the clamping unit 2 on its surface to move. In order to ensure the continuity of processing, a punching mechanism can be added to the path of the transmission chain 105. After the transmission chain 105 moves to the position of the punching mechanism and stops, the drill bit inside the punching mechanism punches the surface of the tobacco pipe fitting 4 to form a drilling section 402.

[0089] When the tobacco pipe fitting 4 clamped by the jaws 2042 driven by the transmission chain 105 moves to the middle position of the back plate 302, at this time, the central axis of the clamping section 401, the central axis of the mounting post 3093, and the central axis of the convex seat 30311 are collinear. And at this time, the pipe plug 405 is placed on the top of the convex seat 30311 in advance by manual or manipulator, so that the convex on the top of the convex seat 30311 abuts against the groove at the bottom of the pipe plug 405 to achieve preliminary fixation. During this process, the lifting of the convex seat 30311 will drive the clamping plate 305 on its side to lift synchronously. Thus, when the pipe plug 405 is pushed into the inside of the sealing section 403, the clamping head 307 is located outside the surface of the sealing section 403, so as to realize the positioning correspondence of the sealing section 403 to the clamping head 307.

[0090] Apply lubricating grease to the opposite surfaces of the sleeve module 3091 and the expansion head 3082 in advance, and start the docking power source 3021. The docking power source 3021 drives the rotating member 30211 to rotate, and the rotating member 30211 drives the displacement table 3022 to move downward, so that the middle opening 3095 in the middle of the movable disk 309 is sleeved on the surface of the tobacco pipe fitting 4. The mounting post 3093 and the laser welding head 3094 pass through the expansion section 404 and the clamping section 401 to reach the connection between the drilling section 402 and the sealing section 403. Thus, the sleeve module 3091 is closed and sleeved on the surface of the clamping section 401 under the push of the closing power source 30911. At this time, the expansion head 3082 has not contacted the expansion section 404 yet.

[0091] Restart the first lifting member 3031, so that the output shaft of the first lifting member 3031 drives the convex seat 30311 and the pipe plug 405 to approach the inside of the plugging section 403, and finally the pipe plug 405 enters the inside of the plugging section 403, thus realizing the plugging preparation of the pipe plug 405 for the plugging section 403;

[0092] Then start the second lifting member 3032, so that the output shaft of the second lifting member 3032 pushes the extension plate 3061 and the vertical plate 3062 to rise, so that the collar plate 306 on the side of the extension plate 3061 rises along the output shaft of the first lifting member 3031, and finally the trigger section 30621 on the surface of the vertical plate 3062 contacts the first linkage member 30541. When the trigger section 30621 rises with the vertical plate 3062, it drives the first linkage member 30541 to rotate. When the first linkage member 30541 rotates, it drives the second linkage member 30542 to rotate through the rotating shaft in the middle of it. When the second linkage member 30542 rotates, it drives the moving plate 3052 to approach the plugging section 403 along the docking groove 30511 inside the clamping plate 305. Finally, during the lifting of the vertical plate 3062, the first linkage member 30541 drives the second linkage member 30542 to rotate, and the second linkage member 30542 drives the moving plate 3052 and the clamping head 307 on its top to approach the plugging section 403, and finally the clamping head 307 presses against the plugging section 403 and fits onto the surface of the plugging section 403. At this time, the vertical plate 3062 stops moving. During the lifting of the collar plate 306, the multiple clamping heads 307 on the side of the plugging section 403 will move to the surface of the plugging section 403 under the lifting of the multiple vertical plates 3062. Then, under the contact of the multiple clamping heads 307 with the surface of the plugging section 403, the plugging section 403 is clamped by relative movable contact;

[0093] When the vertical plate 3062 is lifting, the docking head 30623 at its top will insert into the inside of the docking port 3092, thus completing the linkage docking of the docking port 3092 and the docking head 30623. During the subsequent lifting of the vertical plate 3062, the top of the vertical plate 3062 that is not in contact with the docking head 30623 will drive the movable disk 309 to rise along the limiting rod 3083. Thus, when the lifting of the vertical plate 3062 is completed, that is, after the clamping head 307 contacts the surface of the plugging section 403, the top surface of the sleeve module 3091 on the top of the movable disk 309 is flush with the top surface of the expansion tube section 404.

[0094] Continue to move the displacement stage 3022 downward, so that the displacement stage 3022 drives the expansion head 3082 to approach the inside of the expansion tube section 404, and finally inserts the expansion head 3082 into the inside of the expansion tube section 404. The width profile of the expansion head 3082 squeezes the expansion tube section 404 to expand outward, so that the expansion head 3082 pushes the expansion tube section 404 to contact the sleeve module 3091, so that the expansion tube section 404 is closed and squeezed by the expansion head 3082 and the sleeve module 3091 to form a flared opening, so that the diameter of the opening of the expansion tube section 404 increases, which is convenient for subsequent assembly. At this time, the laser welding head 3094 descends to the connection between the top surface of the pipe plug 405 and the plugging section 403. For the accuracy of welding, a camera can be installed on the side of the laser welding head 3094. By feeding back the welding distance and position information collected by the camera and comparing it with the preset distance and position information, the size and length of the welding beam of the laser can be controlled.

[0095] Start the processing power source 308, so that the processing power source 308 drives the circular turntable 3081 to rotate. The rotation of the circular turntable 3081 will drive the movable disk 309 at its bottom to rotate accordingly. Under the action of the grease pre-applied to the opposite surfaces of the expansion head 3082 and the sleeve module 3091, the expansion head 3082 and the sleeve module 3091 rotate relative to the clamped tobacco pipe part 4 following the circular turntable 3081. Thus, during the lubricated rotation, the expansion head 3082 and the sleeve module 3091 level the expansion tube section 404 by rotation, so as to avoid excessive local stress on a certain part of the expansion tube section 404, thereby reducing local deformation or irregular expansion of the tobacco pipe part 4 during the flaring process, and making the flared opening more uniform. Of course, in order to improve the rotation efficiency, the expansion head 3082 can also be lifted a small distance so that there is a gap between the bottom of the expansion head 3082 and the sleeve module 3091, and the sides of the expansion head 3082 and the sleeve module 3091 still contact the tobacco pipe part 4 under the action of the lubricating oil.

[0096] Of course, an alternative design can also be carried out by setting both the expansion head 3082 and the sleeve module 3091 into an inner and outer two-layer structure, with balls embedded between the inner and outer layers, so that the outer layer of the expansion head 3082 and the sleeve module 3091 rotates relative to the inner layer, so that the rotation of the circular turntable 3081 will not overly drive the inner layer of the expansion head 3082 and the sleeve module 3091 to rotate.

[0097] The rotation of the movable disk 309 drives the docking joint 30623 inserted into it to rotate through the docking interface 3092, and the rotation of the docking joint 30623 is driven by the vertical plate 3062 to make the clamping plate 305 rotate relative to the carrier plate 304 through the rotating member 2 3041, and the collar plate 306 connected to the vertical plate 3062 through the extension plate 3061 rotates relative to the output shaft of the lifting member 1 3031, so that when the multiple clamping plates 305 follow the rotation of the movable disk 309, the multiple clamping column heads 307 on the top thereof will rotate during the rotation of the clamping plate 305. The surface of the plugging section 403 rolls, so that the clamping column head 307 squeezes the inner wall of the plugging section 403 to fit the surface of the pipe plug 405 during rolling, so that the gap between the two is reduced, which helps to improve the sealing performance between the two, and ensures that there will be no leakage at the joint after welding. The unevenness of the opening of the plugging section 403 and its surface will also be relatively rolled and flattened, thereby reducing the gap and unevenness during welding, and helping to stabilize the metal molten pool during the welding process, reducing the occurrence of welding defects such as pores and cracks, and improving the strength and quality of the welded joint;

[0098] After the rotating disk 3081 drives the movable disk 309 to rotate for a preset time, the plugging section 403 is flatly attached to the surface of the pipe plug 405, and then the laser welding head 3094 is started to rotate with the rotating disk 3081, so that the laser welding head 3094 performs rotational welding on the connection between the top of the pipe plug 405 and the inner wall of the plugging section 403, thereby reducing the external welding of the pipe plug 405 and the plugging section 403 in the prior art through internal welding, so that there is a gap directly between the top of the pipe plug 405 and the inner wall of the plugging section 403, thereby Under the frequent flushing of the gas, part of the flue gas that has not been discharged through the drilling section 402 will rush into the gap between the pipe plug 405 and the sealing section 403, aggravating the connection fatigue of the pipe plug 405 and the sealing section 403, and the internal welding of the sealing section 403 and the pipe plug 405 reduces the contact of the gap between the sealing section 403 and the pipe plug 405 with the flue gas, and the gap between the sealing section 403 and the pipe plug 405 is rolled and compressed during the rotation of the clamping column head 307, thereby further improving the connection strength between the pipe plug 405 and the sealing section 403.

[0099] And in the process of rolling the clamping column head 307 relative to the blocking section 403, the middle part of the smoke tube component 4, namely the clamping section 401, is clamped by the clamping claw 2042, and the top of the smoke tube component 4 is lubricated and clamped by the expansion head 3082 and the sleeve module 3091, so that the smoke tube component 4 is fixed in multiple places, and the clamping column head 307 rolls the blocking section 403 and the pipe plug 405 relative to each other, thereby reducing the axial runout of the smoke tube component 4 in the process of leveling the surface of the blocking section 403 by the clamping column head 307, thereby facilitating the laser welding head 3094 to weld the blocking section 403 and the pipe plug 405 more stably.

[0100] After welding is completed, the power source 30911 is closed to drive the sleeve module 3091 to reset, so that the displacement table 3022 resets and the first lifting member 3031 and the back plate 302 reset, so that the tobacco pipe member 4 is exposed from the middle port 3095, so that the jaw 2042 drives the clamped tobacco pipe member 4 to continue to move along with the transmission chain 105 that was originally waiting for welding during shutdown, so that the transmission chain 105 transfers the processed tobacco pipe member 4 to the next process.
