Description

Technical Field

[0001] This invention relates to the field of laser welding technology, and in particular to a laser straight seam welding device for high-strength steel cylinders. Background Technology

[0002] Stainless steel laser welding machines play a vital role in practical applications. Their unique characteristics enable users to improve welding quality and increase production efficiency during production. Laser welding machines can weld refractory materials and dissimilar metals. As a non-contact welding method, laser welding can weld hard-to-reach areas, offering great flexibility. Welding can be performed at room temperature or under special conditions, such as in electromagnetic fields, vacuum, or certain gas environments. Welding speed is high, depth is large, thermal deformation is minimal, and welding precision is high.

[0003] In the straight seam welding process of high-strength steel cylinders, traditional welding equipment has the following shortcomings: the positioning accuracy of the cylinder is low. For example, the existing equipment relies on visual inspection to check whether the weld and welding gun are roughly aligned, and adjusts the fixed position of the cylinder accordingly. It is difficult to ensure that the weld and welding gun are precisely aligned, which often leads to welding deviation and affects product quality. Therefore, corresponding improvements are made to address this problem. Summary of the Invention

[0004] Based on the technical problems existing in the prior art, this invention proposes a laser straight seam welding device for high-strength steel cylinders.

[0005] This invention proposes a laser straight seam welding device for high-strength steel cylinders, comprising a welding table and a welding torch. The welding torch is mounted above the welding table via a planar moving assembly. An opening for the welding torch to move is provided at the top of the welding table. Fixing plates are fixedly connected to both sides of the opening, and fixing strips are fixedly connected to opposite ends of the two fixing plates. A beam plate is fixedly connected inside the welding table, located below the two fixing plates. A positioning plate capable of vertical movement is elastically connected to a mounting groove on the beam plate. A positioning strip for entering the cylinder weld is provided at the top of the positioning plate. A handle is rotatably connected to one end of the welding table, and a roller is mounted on the handle to press the positioning plate upwards. A [missing information - likely a component or element] is fixedly connected to the bottom of the positioning plate. A flexible connecting rod is inserted axially through the sleeve plate and beam plate. The rod abuts against the sleeve plate through the bottom inclined surface. A fixing post is also fixedly connected to the handle to press against the outer end of the rod. The high-strength steel cylinder is placed on the beam plate, and the weld of the cylinder is aligned with the positioning strip on the top of the positioning plate. The positioning strip enters the weld of the cylinder to achieve positioning. Then, the handle is turned. The fixing post on the handle first presses against the outer end of the rod. The rod cooperates with the sleeve plate through the bottom inclined surface, which drives the positioning plate to move downward, thereby causing the positioning strip to disengage from the weld. Then, the handle drives the axle wheel to press against the beam plate. In this way, the cylinder is accurately pressed between the beam plate and the two fixing plates. Then, the planar moving component drives the welding gun to move along the opening to weld the weld of the cylinder.

[0006] Preferably, the positioning plate has a sliding groove for the insertion rod to slide. A spring is fixedly connected to the inner wall of one end of the sliding groove, and the other end of the spring is fixedly connected to the insertion rod. The insertion rod slides in the sliding groove. When the fixing post presses against or releases the insertion rod, the spring deforms and provides elastic restoring force for the insertion rod, ensuring that the insertion rod and the sleeve plate always maintain stable contact and ensuring the smooth adjustment of the positioning plate position.

[0007] Preferably, the bottom inner wall of the mounting groove is provided with multiple circular grooves, and a T-shaped column is provided in the circular groove. A second spring is fixedly connected to the T-shaped column, and the top of the second spring abuts against the positioning plate. A positioning adjustment component is provided below the T-shaped column. The second spring applies an upward elastic force to the positioning plate, assisting the positioning strip to be exposed above the beam plate. The T-shaped column slides in the circular groove. With the help of the positioning adjustment component, the initial height of the T-shaped column can be adjusted, thereby adjusting the original compression force of the second spring.

[0008] Preferably, the positioning adjustment assembly includes a stud, a nut, and an L-rod. The stud is fixedly connected to the side of the welding table. The bottom end of the L-rod is sleeved on the stud and fixed by a set of nuts located on both sides. The L-rod is detachably fixed to the beam plate. The L-rod has multiple inclined surfaces that can contact the bottom end of the T-shaped column. By loosening the nut, the height of the L-rod on the stud is adjusted. Then, the nut is tightened to fix the L-rod. The different inclined surfaces on the L-rod contact the bottom end of the T-shaped column, pushing the T-shaped column to move up and down in the circular groove, thereby adjusting the initial height of the T-shaped column and thus adjusting the original compression force of the second spring.

[0009] Preferably, the assembly further includes a clamping component for pressing the weld seam of the cylinder. The clamping component includes clamping plates, a pull rope, a fixed pulley, and a pedal. Two clamping plates are symmetrically arranged on both sides of the cylinder. The clamping plates are elastically connected to the welding table. The fixed pulley is fixed near the corresponding clamping plate. One end of the pull rope is fixedly connected to the corresponding clamping plate, and the other end passes through the fixed pulley and is fixedly connected to the pedal. The pedal is rotatably connected to the welding table. When the pedal is pressed, the pull rope passes around the fixed pulley and moves the two clamping plates away from the cylinder. This makes it easier to fit the cylinder onto the beam plate. After the cylinder is positioned between the two clamping plates, the pedal is released. Under the action of elastic force, the clamping plates move closer to the cylinder, pressing the weld seam of the cylinder tightly and improving the welding quality.

[0010] Preferably, a pair of guide posts are fixedly connected to the outer side of the clamping plate. Guide sleeves fixedly connected to the welding table are fitted on the guide posts. Springs are also fitted on the guide posts. The two ends of the springs are fixedly connected to the guide sleeves and the clamping plate, respectively. When the clamping plate moves, the guide posts slide along the guide sleeves, which guides the movement of the clamping plate and prevents the clamping plate from deviating. When the clamping plate moves away from the cylinder, the springs are compressed. After the pedal is released, the elastic restoring force of the springs pushes the clamping plate to reset and presses the cylinder, ensuring a stable pressing effect.

[0011] Preferably, the planar moving component comprises a transverse moving module and a longitudinal moving module. The transverse moving module is used to drive the welding torch to move laterally, and the longitudinal moving module is used to drive the welding torch to move longitudinally. According to the position and length of the cylindrical weld, the transverse moving module drives the welding torch to move laterally to align with the transverse position of the weld, and the longitudinal moving module drives the welding torch to move longitudinally to complete the welding of the entire weld. Through the coordination of transverse and longitudinal moving, the welding torch can move accurately in the plane, ensuring that the welding trajectory is consistent with the weld.

[0012] Preferably, the lateral movement module includes a housing, pulleys, a motor, a belt, and a slide. The housing is fixedly connected to the top of the welding table. Two pulleys are rotatably connected to both ends of the housing and connected to each other by a belt. The motor is fixedly connected to the housing and its output shaft is connected to the end of one of the pulleys. The slide is slidably connected to the top of the welding table and is fixedly connected to the belt. When the motor is started, it drives the pulley connected to it to rotate, which drives the other pulley to rotate synchronously through the belt. The slide, which is fixedly connected to the belt, slides laterally along the top of the welding table as the belt moves, thereby driving the longitudinal movement module and welding torch mounted on the slide to move laterally.

[0013] Preferably, the longitudinal movement module includes a frame and a hydraulic rod. The frame is fixedly connected to the top of two slides, and the hydraulic rod is installed at the top of the frame. The hydraulic rod extends and retracts according to welding requirements, thereby driving the welding torch to move longitudinally to meet the movement requirements along the length of the weld during welding.

[0014] Preferably, the welding torch is fixedly connected to a movable seat, which is slidably connected to a mounting seat. The mounting seat is slidably connected to the frame and fixedly connected to the output shaft of the hydraulic rod. A screw is rotatably connected to the mounting seat, and the screw is threadedly connected to the movable seat. The hydraulic rod drives the mounting seat to move longitudinally along the frame over a large range. When the position of the welding torch needs to be finely adjusted, the screw is rotated. Since the movable seat is threadedly connected to the screw and slidably connected to the mounting seat, the rotation of the screw drives the movable seat to slide along the mounting seat, thereby achieving fine position adjustment of the welding torch and ensuring welding accuracy.

[0016] 1. A laser straight seam welding device for high-strength steel cylinders, which can quickly align the cylinder weld seam with the positioning strip on the positioning plate, significantly improving the positioning accuracy and laying the foundation for high-quality welding.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0033] Reference Figures 1-10A laser straight seam welding device for a high-strength steel cylinder includes a welding table 1 and a welding torch 2. The welding torch 2 is mounted above the welding table 1 via a planar moving assembly. The top of the welding table 1 has an opening 3 for the welding torch 2 to move. Fixing plates 4 are fixedly connected to both sides of the opening 3 on the welding table 1. Fixing strips 5 are fixedly connected to the opposite ends of the two fixing plates 4. A beam plate 6 located below the two fixing plates 4 is fixedly connected inside the welding table 1. A positioning plate 8 that can move up and down is elastically connected to the mounting groove 7 on the beam plate 6. The top of the positioning plate 8 is provided with a positioning strip 16 for entering the cylinder weld. A handle 9 is rotatably connected to one end of the welding table 1. A shaft wheel 10 that can press the positioning plate 8 upward is installed on the handle 9. A sleeve plate 11 is fixedly connected to the bottom of the positioning plate 8. An elastically connected insert rod 12 is passed through the beam plate 6 axially. The insert rod 12 abuts against the sleeve plate 11 through the inclined surface at the bottom. A fixing post 13 that can press against the outer end of the insert rod 12 is also fixedly connected to the handle 9.

[0034] In use, the high-strength steel cylinder is placed on the beam plate 6, aligning the weld of the cylinder with the positioning strip 16 on the top of the positioning plate 8, so that the positioning strip 16 enters the weld of the cylinder for positioning. Then, the handle 9 is turned, and the fixing post 13 on the handle 9 first presses against the outer end of the insert rod 12. The insert rod 12 cooperates with the sleeve plate 11 through the bottom inclined surface, driving the positioning plate 8 to move downward, thereby causing the positioning strip 16 to disengage from the weld. Then, the handle 9 drives the axle wheel 10 to press against the beam plate 6 upward, so that the cylinder is precisely pressed between the beam plate 6 and the two fixing plates 4. Subsequently, the planar moving component drives the welding gun 2 to move along the opening 3 to weld the weld of the cylinder.

[0035] In this invention, the positioning plate 8 is provided with a sliding groove 14 for the insertion rod 12 to slide. A spring 15 is fixedly connected to the inner wall of one end of the sliding groove 14, and the other end of the spring 15 is fixedly connected to the insertion rod 12.

[0036] During use, the insertion rod 12 slides in the slide groove 14. When the fixing post 13 presses against or releases the insertion rod 12, the spring 15 stretches and deforms, providing elastic restoring force for the insertion rod 12, ensuring that the insertion rod 12 and the sleeve plate 11 always maintain stable contact, and ensuring the smooth adjustment of the position of the positioning plate 8.

[0037] In this invention, the bottom inner wall of the mounting groove 7 is provided with a plurality of circular grooves 20, and a T-shaped column 21 is provided in the circular groove 20. A spring 22 is fixedly connected to the T-shaped column 21, and the top of the spring 22 abuts against the positioning plate 8. A positioning adjustment component is provided below the T-shaped column 21.

[0038] In use, spring 22 applies an upward elastic force to the positioning plate 8, the auxiliary positioning strip 16 is exposed above the beam plate 6, and the T-shaped column 21 slides in the circular groove 20. With the help of the positioning adjustment component, the initial height of the T-shaped column 21 can be adjusted, thereby adjusting the original compression force of spring 22.

[0039] In this invention, the positioning adjustment assembly includes a stud 17, a nut 18, and an L-rod 19. The stud 17 is fixedly connected to the side of the welding table 1. The bottom end of the L-rod 19 is sleeved on the stud 17 and fixed by a set of nuts 18 located on both sides. The L-rod 19 is detachably fixed to the beam plate 6. The L-rod 19 is provided with multiple inclined surfaces that can contact the bottom end of the T-shaped column 21.

[0040] In use, the height of L-rod 19 on stud 17 is adjusted by loosening nut 18, and then nut 18 is tightened to fix L-rod 19. Different inclined surfaces on L-rod 19 contact the bottom end of T-shaped column 21, pushing T-shaped column 21 to move up and down in circular groove 20, thereby adjusting the initial height of T-shaped column 21 and thus adjusting the original compression force of spring 22.

[0041] In this invention, the planar movement component comprises a transverse movement module and a longitudinal movement module. The transverse movement module drives the welding torch 2 to move laterally, and the longitudinal movement module drives the welding torch 2 to move longitudinally. The transverse movement module includes a housing 30, pulleys 31, a motor 32, a belt 33, and a slide 34. The housing 30 is fixedly connected to the top of the welding table 1. Two pulleys 31 are rotatably connected to both ends of the housing 30, and the two pulleys 31 are connected by the belt 33. The motor 32 is fixedly connected to the housing 30, and its output shaft is connected to the end of one of the pulleys 31. The slide... 34 is slidably connected to the top of the welding table 1, and the slide 34 is fixedly connected to the belt 33; the longitudinal movement module includes a frame 35 and a hydraulic rod 37. The frame 35 is fixedly connected to the top of the two slides 34, and the hydraulic rod 37 is installed on the top of the frame 35; the welding torch 2 is fixedly connected to the movable seat 38, the movable seat 38 is slidably connected to the mounting seat 36, the mounting seat 36 is slidably connected to the frame 35 and fixedly connected to the output shaft of the hydraulic rod 37, and a screw 39 is rotatably connected to the mounting seat 36, and the screw 39 is threadedly connected to the movable seat 38;

[0042] In use, the motor 32 starts, driving the pulley 31 connected to it to rotate. Through the belt 33, it drives another pulley 31 to rotate synchronously. The slide 34, which is fixedly connected to the belt 33, slides laterally along the top of the welding table 1 as the belt 33 moves, thereby driving the longitudinal movement module and welding torch 2 mounted on the slide 34 to move laterally. The hydraulic rod 37 drives the mounting base 36 to move longitudinally along the frame 35 over a large range, thereby driving the welding torch 2 to move longitudinally to meet the movement requirements along the length of the weld during welding. When it is necessary to fine-tune the position of the welding torch 2, the screw 39 is rotated. Since the movable seat 38 is threadedly connected to the screw 39 and slidably connected to the mounting base 36, the rotation of the screw 39 drives the movable seat 38 to slide along the mounting base 36, thereby achieving fine position adjustment of the welding torch 2 and ensuring welding accuracy.

[0043] In another embodiment of the present invention, a laser straight seam welding device for a high-strength steel cylinder further includes a clamping assembly for pressing the weld seam of the cylinder. The clamping assembly includes a clamping plate 23, a pull rope 24, a fixed pulley 25, and a pedal 26. The two clamping plates 23 are symmetrically arranged on both sides of the cylinder. The clamping plates 23 are elastically connected to the welding table 1. The fixed pulley 25 is fixed near the corresponding clamping plate 23. One end of the pull rope 24 is fixedly connected to the corresponding clamping plate 23, and the other end passes through the fixed pulley 25 and is fixedly connected to the pedal 26. The pedal 26 is rotatably connected to the welding table 1.

[0044] When in use, step on the pedal 26, and the pull rope 24 will pass around the fixed pulley 25 to move the two clamping plates 23 away from the cylinder. This makes it easier to fit the cylinder onto the beam plate 6. After the cylinder is positioned between the two clamping plates 23, release the pedal 26. The clamping plates 23 will move closer to the cylinder under the action of elastic force, pressing the two sides of the cylinder's weld seam tightly and improving the welding quality.

[0045] In this invention, a pair of guide posts 28 are fixedly connected to the outer side of the clamping plate 23. A guide sleeve 27 fixedly connected to the welding table 1 is sleeved on the guide post 28. A spring 29 is also sleeved on the guide post 28. The two ends of the spring 29 are fixedly connected to the guide sleeve 27 and the clamping plate 23 respectively.

[0046] When in use, as the clamping plate 23 moves, the guide post 28 slides along the guide sleeve 27, which guides the movement of the clamping plate 23 and prevents the clamping plate 23 from shifting. The spring 3 29 is compressed when the clamping plate 23 moves away from the cylinder. After the pedal 26 is released, the elastic restoring force of the spring 3 29 pushes the clamping plate 23 to reset and press the cylinder, ensuring a stable pressing effect.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
