Description

Technical Field

[0001] This invention relates to the field of laser welding of circular tubes, specifically to a pipe-to-pipe auxiliary device using laser welding. Background Technology

[0002] Laser welding is a precision welding technology that uses a high-energy-density laser beam as a heat source to melt the metal at the joint of the workpiece and then cool and solidify it, thereby achieving a firm connection.

[0003] In actual production applications, two sections of round tubes are usually butted together. The butt joint surfaces of the round tubes are ground to remove oil and oxide scale, ensuring that the end surfaces are flat and burr-free. Then, the workers fix the two ends of the round tubes on a coaxial rotating fixture, adjust the coaxiality, control the butt joint gap, and then turn on the laser. At the same time, the fixture drives the round tubes to rotate at a uniform speed to complete the ring welding.

[0004] When using laser welding equipment for round tubes, manual intervention is usually required for loading, positioning, and unloading of the tubes. This limits the efficiency of laser welding of round tubes. Therefore, there is an urgent need for a highly efficient and automated laser welding device for round tubes in actual production operations to reduce the labor intensity of workers and improve the efficiency of enterprise production. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a pipe-to-pipe auxiliary device using laser welding to solve the technical problems mentioned in the background above.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pipe-to-pipe auxiliary device using laser welding, comprising a worktable and a laser welding device. A first driving mechanism is mounted on the top of the worktable, and a second driving mechanism for assisting the first driving mechanism is also mounted thereon. The first driving mechanism includes a first guide rail assembly connected to the worktable. A mounting bracket is mounted on the side of the first guide rail assembly. A first threaded rod is provided on one side of the mounting bracket, and two sets of driving rollers are rotatably connected to the other side. The driving rollers are divided into two sections by providing opening and closing grooves. A transmission shaft is rotatably connected inside the mounting bracket. The transmission shaft is connected to the first driving assembly, and the transmission shaft and the driving rollers are connected by a... The first drive mechanism includes a first pulley assembly for transmission connection and a threaded sleeve rotatably connected to the worktable. The threaded sleeve is threadedly connected to the first threaded rod and is connected to a second drive assembly. The worktable is equipped with a feeding chamber for storing multiple sets of round tubes to be welded side by side. The feeding chamber is also equipped with a feeding mechanism for pushing the round tubes in the feeding chamber. Limiting blocks are provided on both sides of the outlet of the feeding chamber at the top of the worktable. The limiting blocks match the opening and closing grooves to prevent the round tubes from rolling off when they reach the outlet of the feeding chamber. The worktable is also equipped with a discharging chamber for storing the round tubes that have been welded.

[0007] By adopting the above technical solution, an arc-shaped feeding chamber is set up to hold multiple sets of round tubes side by side. Then, the feeding mechanism is used to push the multiple sets of round tubes to be fed in a way that raises them one by one from bottom to top. Then, by the two sets of drive mechanisms approaching each other, the two sections of the top set of round tubes can be clamped and lifted. Then, the drive mechanism works to drive the round tubes to rotate. At the same time, the laser welding equipment is used to perform ring welding on the two sections of round tubes. The drive mechanism consists of multiple drive rollers. When the drive rollers are installed, an opening and closing groove is retained. When the round tube emerges from the feed chamber, if the drive rollers of the drive mechanism are to clamp and lift it, the round tube needs to completely emerge from the feed chamber and the center of the round tube needs to be higher than the center of the drive roller. However, this can easily cause the round tube to roll off. Therefore, a limiting block matching the opening and closing groove is set at the edge of the feed chamber outlet. The limiting block can prevent the uppermost set of round tubes from rolling off without affecting the fit between the drive rollers of the two sets of drive mechanisms and the round tube. When the round tube welding is completed, the drive mechanism located above the unloading chamber slowly resets, while the feeding mechanism continues to push the subsequent set of round tubes to rise and feed. At this time, the lifting effect of the round tube feeding and the drive mechanism above the unloading chamber moving away from the loss of support ensure that the welded round tube does not fall into the feeding chamber but slides into the unloading chamber. When welding round tubes using the welding equipment of this application, only personnel are needed to be in the feeding chamber for centralized loading and unloading, and the loading and unloading of round tubes are carried out automatically by the equipment, thereby improving the work efficiency of round tube welding.

[0008] The present invention is further configured such that a first telescopic component is provided on the top of the workbench, and a top pressure wheel is installed on the bottom of the first telescopic component, with the top pressure wheel located directly above the outlet of the feed chamber.

[0009] Preferably, by setting a top pressure roller, the two sections of the round pipe to be welded are pressed together by adjusting the height of the top pressure roller, so that the rotation of the two sections of the round pipe is more stable.

[0010] The present invention is further configured such that the feeding mechanism includes a second threaded rod rotatably connected to the bottom of the workbench, and a push plate is externally threaded to the second threaded rod. The push plate and the inner wall of the workbench are slidably installed through a second guide rail assembly. The push plate is used to push multiple sets of round tubes in the feeding chamber to move laterally.

[0011] Preferably, by setting a push plate that can move laterally, the push plate moves within the feeding chamber to push multiple sets of round tubes to be welded, so that the round tubes can be fed one by one within the feeding chamber.

[0012] The present invention is further configured such that the feeding mechanism includes a feeding wheel rotatably connected to the inner side of the workbench and an electromagnetic clutch installed on the side of the workbench. The electromagnetic clutch and the feeding wheel are connected by a second pulley assembly, and the electromagnetic clutch and the second threaded rod are connected by a gear set.

[0013] Preferably, by setting a feeding wheel, the rotation of the feeding wheel allows the arc-shaped fitting groove on the side of the feeding wheel to match the movement of the round tube, so that the feeding wheel can both drive the round tube to feed and prevent the round tube from retracting when the electromagnetic clutch is disengaged and the feeding wheel stops rotating, making it convenient for the welding equipment to add round tubes a second time.

[0014] The present invention is further configured such that the feeding mechanism is provided in two sets, the two sets of feeding mechanisms are used to push and feed multiple sets of round tubes stored side by side in the feeding chamber, and the second threaded rods of the two sets of feeding mechanisms are connected to a third drive assembly.

[0015] Preferably, by setting up two sets of feeding mechanisms, two sections of circular tubes stored side by side in the feeding chamber can be pushed and fed.

[0016] The present invention is further configured such that multiple sets of arc-shaped fitting grooves are provided on the side of the feeding wheel, the size of the arc-shaped fitting grooves matches the size of the circular tube, and adjacent arc-shaped fitting grooves fit into the continuously distributed circular tubes when rotating with the feeding wheel.

[0017] Preferably, by setting a feeding wheel with an arc-shaped fitting groove, the feeding wheel can prevent the round tube from retracting.

[0018] The present invention is further configured such that a baffle for positioning the circular tube is provided in the middle position inside the unloading chamber, and a guide slope and a flexible anti-collision layer are provided inside the feeding chamber.

[0019] Preferably, by setting a baffle inside the feeding chamber, the operator can be assisted in aligning the ends of the round tube when adding it, and the first driving mechanism has two sets of driving rollers with a recess between them to avoid the weld seam.

[0020] The invention is further configured such that clamping mechanisms are installed on both sides of the workbench, and the two sets of clamping mechanisms are used to push the end faces of the two round tubes to align. The clamping mechanism includes a fixed frame fixedly connected to the workbench. A third threaded rod is threadedly connected inside the fixed frame. A handle is provided at one end of the third threaded rod, and a connecting plate is rotatably connected at the other end. A guide rod is provided on the side of the connecting plate. The guide rod and the fixed frame are movably connected through each other. A second telescopic component is provided on the side of the connecting plate, and a top pressure plate is rotatably connected to the end of the second telescopic component.

[0021] Preferably, by setting a clamping mechanism, two separate circular tubes can be merged and aligned. The clamping mechanism can manually adjust the initial position of the second telescopic component so that the welding equipment can adapt to circular tubes of different lengths. The clamping mechanism is used to axially calibrate the circular tube, while the top pressure roller and drive roller are used to calibrate the circular tube in the vertical direction.

[0022] In summary, the present invention has the following main beneficial effects: 1. This invention uses an arc-shaped feeding chamber to hold multiple sets of round tubes side by side. Then, a feeding mechanism is used to push the multiple sets of round tubes to be fed one by one from bottom to top. Then, two sets of driving mechanisms are brought close to each other to clamp and lift the two sections of the top set of round tubes. Then, the driving mechanism works to drive the round tubes to rotate. At the same time, laser welding equipment is used to perform circumferential welding on the two sections of round tubes. The drive mechanism consists of multiple drive rollers. When the drive rollers are installed, an opening and closing groove is retained. When the round tube emerges from the feed chamber, if the drive rollers of the drive mechanism are to clamp and lift it, the round tube needs to completely emerge from the feed chamber and the center of the round tube needs to be higher than the center of the drive roller. However, this can easily cause the round tube to roll off. Therefore, a limiting block matching the opening and closing groove is set at the edge of the feed chamber outlet. The limiting block can prevent the uppermost set of round tubes from rolling off without affecting the fit between the drive rollers of the two sets of drive mechanisms and the round tube. When the round tube welding is completed, the drive mechanism located above the unloading chamber slowly resets, while the feeding mechanism continues to push the subsequent set of round tubes to rise and feed. At this time, the lifting effect of the round tube feeding and the drive mechanism above the unloading chamber moving away from the loss of support ensure that the welded round tube does not fall into the feeding chamber but slides into the unloading chamber. When welding round tubes using the welding equipment of this application, only personnel are needed to be in the feeding chamber for centralized loading and unloading, and the loading and unloading of round tubes are carried out automatically by the equipment, thereby improving the work efficiency of round tube welding.

[0023] 2. This invention, through the setting of a feeding mechanism, not only feeds round tubes one by one, but also prevents the round tubes from retracting, facilitating secondary feeding of round tubes during equipment operation. The feeding mechanism mainly includes a push plate and a feeding wheel, which work together. The push plate moves horizontally to push multiple sets of round tubes laterally within the feeding chamber, while the rotation of the feeding wheel matches the movement of the round tubes. Multiple sets of arc-shaped fitting grooves matching the round tubes are opened on the outside of the feeding wheel. As the round tubes are pushed and moved by the push plate, the feeding wheel rotates, so that each set of arc-shaped fitting grooves on its side can fit into the continuous round tubes. Thus, the feeding wheel can both realize the lateral movement of the round tubes through rotation and prevent the round tubes from retracting when the feeding wheel stops rotating. The rotation of the feeding wheel and the movement of the push plate are linked together and equipped with an electromagnetic clutch that can cut off the drive. When the feeding chamber needs to add round tubes a second time, the electromagnetic clutch is disengaged, the feeding wheel loses its drive source and stops rotating, which can prevent the existing round tubes from retracting. The push plate is reset, and multiple round tubes can be added again in the gap between the feeding wheel and the push plate. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of the present invention will now be described.

[0028] Please see Figures 1-10A pipe-to-pipe auxiliary device using laser welding includes a worktable 1 and a laser welding device 6. A first drive mechanism 4 is mounted on the top of the worktable 1, and a second drive mechanism 5 for assisting the first drive mechanism 4 is also mounted. The second drive mechanism 5 can be configured to be the same as the first drive mechanism 4, but the driving directions of the two must be synchronized. The second drive mechanism 5 can also be configured as an auxiliary roller that only moves laterally. The first drive mechanism 4 includes a first guide rail assembly 401 connected to the worktable 1. A mounting bracket 402 is mounted on the side of the first guide rail assembly 401. A first threaded rod 408 is provided on one side of the mounting bracket 402, and two sets of drive rollers 403 are rotatably connected to the other side. The drive rollers 403 are divided into two sections by providing an opening and closing groove 404. A transmission shaft 405 is rotatably connected inside the mounting bracket 402. The transmission shaft 405 is connected to a first drive assembly 406. The first drive assembly 406, such as a stepper motor, drives the transmission shaft 405 to rotate. The transmission shaft 405 and the drive rollers 403 are connected by a first pulley assembly 407. Mechanism 4 also includes a threaded sleeve 409 rotatably connected to the worktable 1. The threaded sleeve 409 is threadedly connected to the first threaded rod 408, and the threaded sleeve 409 is connected to a second drive assembly 410. The second drive assembly 410, such as a stepper motor, drives the threaded sleeve 409 to rotate. The worktable 1 is equipped with a feeding chamber 2, which is used to store multiple sets of round tubes to be welded side by side. The feeding chamber 2 is also equipped with a feeding mechanism 9, which is used to push the round tubes in the feeding chamber 2 for feeding. The top of the worktable 1... Limiting blocks 12 are provided on both sides of the outlet of the feeding chamber 2. The limiting blocks 12 match the opening and closing groove 404 to prevent the round tube from rolling off when it reaches the outlet of the feeding chamber 2. The workbench 1 is also provided with a unloading chamber 3, which is used to store the round tubes that have been welded. When the round tubes are welded by the welding equipment of this application, only the staff needs to be in the feeding chamber 2 to load the material and in the unloading chamber 3 to retrieve the material. The loading and unloading of the round tubes during the welding process is carried out automatically by the equipment, thereby improving the working efficiency of the round tube welding.

[0029] Please refer to the above embodiments for further details. Figure 1 The top of the workbench 1 is provided with a first telescopic component 7, and the bottom of the first telescopic component 7 is provided with a top pressure roller 8. The top pressure roller 8 is located directly above the outlet of the feed chamber 2. By setting the top pressure roller 8, the two sections of round pipe to be welded are pressed by adjusting the height of the top pressure roller 8, so that the rotation of the two sections of round pipe is more stable.

[0030] Please refer to the above embodiments for further details. Figure 6The feeding mechanism 9 includes a second threaded rod 901 rotatably connected to the bottom of the workbench 1. The second threaded rod 901 is externally threaded with a push plate 902. The push plate 902 and the inner wall of the workbench 1 are slidably installed through a second guide rail assembly 903. The push plate 902 is used to push multiple sets of round tubes in the feeding chamber 2 to move laterally. By setting the push plate 902 which can move laterally, the push plate 902 moves in the feeding chamber 2 to push multiple sets of round tubes to be welded to move, so that the round tubes can be fed one by one in the feeding chamber 2.

[0031] Please refer to the above embodiments for further details. Figure 6 The feeding mechanism 9 also includes a feeding wheel 904 rotatably connected to the inner side of the workbench 1 and an electromagnetic clutch 905 installed on the side of the workbench 1. The electromagnetic clutch 905 and the feeding wheel 904 are connected by a second pulley assembly 906. The electromagnetic clutch 905 and the second threaded rod 901 are connected by a gear set 907. By setting the feeding wheel 904, the rotation of the feeding wheel 904 allows the arc-shaped fitting groove on the side of the feeding wheel 904 to match the movement of the round tube. This allows the feeding wheel 904 to both drive the round tube to feed and prevent the round tube from retracting when the electromagnetic clutch 905 is disengaged and the feeding wheel 904 stops rotating under damping action. This facilitates the secondary addition of round tubes by the welding equipment.

[0032] Please refer to the above embodiments for further details. Figure 2 and Figure 5 The feeding mechanism 9 is provided with two sets. The two sets of feeding mechanisms 9 are used to push and feed multiple sets of round tubes stored side by side in the feeding chamber 2. The second threaded rods 901 of the two sets of feeding mechanisms 9 are connected to the third drive assembly 10. By setting two sets of feeding mechanisms 9, two sections of round tubes stored side by side in the feeding chamber 2 can be pushed and fed.

[0033] Please refer to the above embodiments for further details. Figure 6 The side of the feeding wheel 904 has multiple sets of arc-shaped fitting grooves. The size of the arc-shaped fitting grooves matches the size of the round tube. When the adjacent arc-shaped fitting grooves rotate with the feeding wheel 904, they fit into the continuously distributed round tubes. By setting the feeding wheel 904 with arc-shaped fitting grooves, the feeding wheel 904 can prevent the round tube from retracting.

[0034] Please refer to the above embodiments for further details. Figure 2 The inner middle position of the unloading chamber 3 is provided with a baffle for positioning the round tube. The inner side of the feeding chamber 2 is provided with a guide slope 11 and a flexible anti-collision layer. By providing a baffle inside the feeding chamber 2, the workers can help align the ends of the round tube when adding it. The first driving mechanism 4 is provided with two sets of driving rollers 403, and the two sets of driving rollers 403 are recessed to avoid the weld seam.

[0035] Please refer to the above embodiments for further details. Figure 7 Clamping mechanisms 13 are installed on both sides of the workbench 1. The two clamping mechanisms 13 are used to push the end faces of the two round tubes to align. The clamping mechanism 13 includes a fixed frame 1301 fixedly connected to the workbench 1. The fixed frame 1301 is internally threaded with a third threaded rod 1302. One end of the third threaded rod 1302 is provided with a handle, and the other end is rotatably connected to a connecting plate 1303. A guide rod 1304 is provided on the side of the connecting plate 1303. The guide rod 1304 and the fixed frame 1301 are movably connected through each other. A second telescopic component 1305 is provided on the side of the connecting plate 1303. The end of the second telescopic component 1305 is rotatably connected to a top pressure plate 1306. By setting the clamping mechanism 13, the two separate round tubes can be merged and aligned. The clamping mechanism 13 can manually adjust the initial position of the second telescopic component 1305 so that the welding equipment can adapt to round tubes of different lengths. The clamping mechanism 13 is used for axial calibration of the round tube, and the top pressure roller 8 and the drive roller 403 are used for vertical calibration of the round tube.

[0036] In practical operation, when the welding equipment is working continuously, the third drive assembly 10 is activated to drive the second threaded rods 901 of the two sets of feeding mechanisms 9 to rotate, thereby causing the two sets of push plates 902 to move laterally and push the multiple sets of round tubes in the feeding chamber 2. At the same time, the second threaded rods 901 drive the feeding wheel 904 to rotate through the gear set 907, the electromagnetic clutch 905 and the second pulley assembly 906. Under the transmission and adjustment action of the gear set 907, the rotation speed of the multiple sets of arc-shaped fitting grooves on the side of the feeding wheel 904 is matched with the speed of the multiple sets of round tubes moving laterally, that is, the multiple sets of round tubes can continuously engage into the multiple sets of arc-shaped fitting grooves of the feeding wheel 904 when they move laterally.

[0037] Multiple sets of round tubes move within the feeding chamber 2 and emerge from its outlet. Once the uppermost set of round tubes reaches a designated height, the feeding mechanism 9 stops working. The center of the round tubes at this height is higher than the center of the drive roller 403, and the round tubes at this height will not roll off the sides under the restriction of the limiting block 12. Subsequently, two sets of second drive components 410 are activated to drive the connected threaded sleeve 409 to rotate, thereby pushing the first threaded rod 408 to move. In other words, the first threaded rod 408 pushes the mounting bracket 402 to move laterally, allowing the first drive mechanism 4 and the second drive mechanism 5 to move closer to each other. During the movement of the first drive mechanism 4 and the second drive mechanism 5, the opening and closing groove 404 aligns with the limiting block 12. The limiting block 12 will not affect the contact between the first drive mechanism 4, the second drive mechanism 5 and the round tubes. The movement of the drive roller 403 will clamp and lift the round tubes. Then, two sets of second telescopic components 1305 work to push two sets of top pressure plates 1306 closer to each other, so that the end faces of the two sets of round tubes are aligned.

[0038] Next, the first drive assembly 406 is activated to drive the transmission shaft 405 to rotate. The transmission shaft 405 drives the drive roller 403 to rotate through multiple sets of first belt pulley assemblies 407. The rotation of the drive roller 403 causes the round tube to rotate slowly. Meanwhile, the first telescopic assembly 7 works to push the top pressure roller 8 to drop in height. The top pressure roller 8 is used to press the two sections of the round tube together. While the two sections of the round tube are rotating at a constant speed, the laser welding equipment 6 is activated to perform circumferential welding on the joint of the two sections of the round tube.

[0039] After the two sections of round tubes are welded, the feeding mechanism 9 continues to work to push and raise the next set of round tubes. At the same time, the first drive mechanism 4 resets and no longer supports the welded round tubes. The next set of round tubes raised from the feed chamber 2 is located below the welded round tubes and lifts them up, which can prevent the welded round tubes from falling back into the feed chamber 2. This allows the welded round tubes to slide smoothly from the guide slope 11 into the unloading chamber 3. The second drive mechanism 5 also begins to reset to prevent it from blocking the other set of round tubes from emerging.

[0040] When the welding equipment needs to add round tubes midway, the drive connection of the electromagnetic clutch 905 is disconnected, so that the loading wheel 904 stops rotating under the action of damping. In this way, the loading wheel 904 can prevent the existing round tubes in the feeding chamber 2 from retracting. Then, the third drive assembly 10 is driven in reverse to reset the two sets of push plates 902 to the starting point. Then, the operator can add new round tubes in the gap between the loading wheel 904 and the push plate 902. Finally, the third drive assembly 10 is restarted to push multiple sets of round tubes to move. Then, the newly added round tubes can be connected with the existing round tubes.
