Description

Technical Field

[0001] This invention belongs to the field of steel structure welding technology, specifically a steel structure welding guide and alignment device for ship hull structure manufacturing. Background Technology

[0002] Currently, shipbuilding begins with constructing the hull. Large steel hulls are typically assembled by welding together numerous steel plates, which are usually rectangular to allow for alignment and welding of adjacent plates. Existing technology generally involves welding the hull sections by experienced operators using handheld welding torches, such as for deck plates and the hull itself. While manual welding is convenient and flexible, it cannot guarantee precise welding along the joints. Handheld welding is prone to errors, leading to weak welds and even affecting the overall structural integrity of the hull. Furthermore, the welding of hull steel structures involves numerous curved and flat surface welds, making it difficult for workers to control the welding quality.

[0003] Therefore, it is necessary to develop a steel structure welding guide and alignment device suitable for different welding conditions in ship hull structure manufacturing. Summary of the Invention

[0004] The purpose of this invention is to provide a steel structure welding guide and alignment device for ship hull structure manufacturing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a steel structure welding guide and alignment device for ship hull structure manufacturing, comprising several guide frames connected end to end in sequence, with fixed components movably connected to the back faces of two guide frames at both ends, a insertion slot I being provided at one end of several guide frames in the middle, with locking teeth fixedly connected inside the insertion slot I, and an insertion plate fixedly connected to the other end of several guide frames in the middle, with positioning teeth fixedly connected to the other end of the insertion plate, two adjacent guide frames being connected through the insertion slot I and the insertion plate, the insertion plate being inserted into the insertion slot I, the positioning teeth engaging with the locking teeth, positioning components located on the upper and lower sides of the insertion slot I being provided on the top of the guide frame, a rotating shaft being sleeved inside the insertion plate, with snap-fit ​​sliders fixedly connected to the upper and lower ends of the rotating shaft and disposed inside the positioning components, and an adapter overlap frame being provided on the front of the guide frame, with a welding gun sleeve being provided at one end of the adapter overlap frame;

[0006] Preferably, the top of the adapter overlap frame is rotatably snapped with a clamping assembly, and the other end of the clamping assembly is movably connected to two left and right rollers located on the back of the guide frame. The rollers roll in contact with the surface of the guide frame, and the bottom of the adapter overlap frame is movably connected to an adapter overlap member located directly in front of the rollers.

[0007] Both of the fixing components include a connecting shaft, the opposing surfaces of the two connecting shafts are fixedly connected to the opposing back surfaces of two guide frames located at both ends, and the other end of the connecting shaft is rotatably sleeved with a connecting seat, the connecting seat contacting the guide frame.

[0008] Preferably, the bottom of the connecting seat has a limiting groove, a magnet block is slidably engaged inside the limiting groove, a lead screw is threaded inside the magnet block, and a first anti-detachment post is fixedly connected to the top of the lead screw and rotatably engaged inside the connecting seat. The top of the first anti-detachment post extends to the top of the connecting seat and is fixedly connected to a knob.

[0009] Preferably, the positioning component includes two snap-fit ​​grooves formed at the top and bottom of the guide frame, the snap-fit ​​grooves being connected to the insertion grooves, the snap-fit ​​slider being slidably snapped into the inside of the snap-fit ​​grooves, the inside of the guide frame having two positioning grooves located on the front and rear sides of the snap-fit ​​grooves, the inside of the positioning grooves having two positioning sliders located on the front and rear sides of the snap-fit ​​slider being slidably snapped into, the positioning sliders being fixedly connected to the snap-fit ​​sliders, and the inside of the positioning grooves having a positioning spring, the two ends of the positioning springs being connected to the positioning sliders and the inner walls of the positioning grooves respectively.

[0010] Preferably, the inner cavity of the welding torch sleeve has a trapezoidal cross-section, the welding torch sleeve has a non-closed-loop structure, and the inner diameter of the welding torch sleeve is adapted to the outer diameter of the welding torch nozzle.

[0011] Preferably, a connecting plate is provided at the top of the other end of the adapter overlap frame. The top of the adapter overlap frame has two left and right insertion slots located at the bottom of the connecting plate. The bottom of the connecting plate is connected to two left and right protective plates. The bottom of the protective plates passes through the insertion slots and extends to the bottom of the adapter overlap frame. The opposite ends of the two protective plates are the same size, and the opposite ends of the two protective plates are different in size and are interlocked. The interlocking ends of the two protective plates do not contact each other. The size of the protective plate on the side away from the welding gun sleeve is larger than the size of the protective plate on the side closer to the welding gun sleeve. The top of the adapter overlap frame has a fixing hole located inside the insertion slots. Several elastic metal wires located inside the two protective plates are inserted into the fixing hole.

[0012] Preferably, the adapter includes an overlap roller sleeve that rolls in contact with the front of the guide frame. The overlap roller sleeve has two movable plates inside, one upper and one lower. The bottom of the lower movable plate is connected to a first clamping plate extending to the bottom of the guide frame, and the top of the upper movable plate is connected to a second clamping plate extending to the top of the guide frame.

[0013] Preferably, the second clamping plate is rotatably engaged inside the fitting overlap frame, and the overlap roller bushing is provided with two clamping springs located outside the first clamping plate and the second clamping plate, with the two ends of the clamping springs respectively connected to the movable plate and the inner wall of the overlap roller bushing.

[0014] Preferably, the clamping assembly includes a connecting sleeve rod rotatably connected to the top of the adapter overlap frame and directly above the adapter overlap piece. A second anti-detachment column is movably sleeved inside the connecting sleeve rod. A connecting rod is fixedly connected to the side of the second anti-detachment column near the roller shaft. The other end of the connecting rod extends to the outside of the connecting sleeve rod and is fixedly connected to a mounting base. The bottom of the mounting base is movably connected to the two roller shafts.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. The present invention uses several guide frames connected end to end, whose curvature can be freely adjusted to adapt to the guidance of straight or curved weld seams. Due to the mutual meshing of locking teeth and positioning teeth, adjacent guide frames are prevented from bending arbitrarily under the constraints of the rotating shaft, snap-fit ​​slider and positioning components. This ensures that the overall curvature of the guide frame can be fixed after adjustment. Furthermore, the two fixing components can be used to adapt it to one side of the weld seam to facilitate the continuous movement of the welding torch.

[0017] 2. Because the adapter lap frame itself can rotate within a limited range due to the restriction of the second clamping plate, the position of the welding gun sleeve can still be slightly adjusted after the overall curvature of the guide frame is fixed. This allows the welding gun nozzle to move along the weld seam on one side of the guide frame through the welding gun sleeve and the adapter lap frame, while also making slight adjustments at any time relative to the fixed curvature trajectory of the guide frame itself, so as to ensure a smoother welding transition for non-smooth weld seams.

[0018] 3. The present invention ensures that the guide frame as a whole can rotate relative to the two fixed components by means of a connecting shaft, thereby adjusting the angle of the bending plane of the guide frame as a whole. This allows the bending plane of the guide frame as a whole to adapt to curved welds parallel to the working surface, as well as curved welds perpendicular to the working surface, improving its flexibility of application and making it more suitable for large-area curved welding of ship cabin steel plates perpendicular to the working surface.

[0019] 4. This invention uses elastic metal wires to clean both sides and the inside of the weld, preventing dust from affecting the weld's strength. The protective plate, which adheres to the surface of the steel plate, can scrape off most of the dust as it slides along the steel plate surface with the adapter lap frame. The connecting plate and fixing holes facilitate the injection of hot air into the bottom of the adapter lap frame and between the two plug plates to heat the elastic metal wires. At the same time, it can blow away the dust near the weld. Thus, under the action of the elastic metal wires, the airflow inside and around the weld is heated to preheat the weld and improve the welding effect. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1 to 10 As shown, this embodiment of the invention provides a steel structure welding guide and alignment device for ship hull structure manufacturing, including a plurality of guide frames 1, which are connected end to end in sequence. Each pair of guide frames 1 at both ends has a fixing component 2 movably connected to its opposite side. One end of one of the guide frames 1 in the middle section has an insertion groove 3, and a locking tooth 4 is fixedly connected inside the insertion groove 3. The other end of the guide frames 1 in the middle section is fixedly connected to an insertion plate 5, and a positioning tooth 6 is fixedly connected to the other end of the insertion plate 5. Two adjacent guide frames 1 are connected through the insertion groove 3 and the insertion plate 5, with the insertion plate 5 inserted into the insertion groove 3. The positioning tooth 6 meshes with the locking tooth 4. The top of the guide frame 1 is provided with positioning components 9 located on the upper and lower sides of the insertion slot 3. The inside of the insertion plate 5 is fitted with a rotating shaft 7. Both the upper and lower ends of the rotating shaft 7 are fixedly connected with snap-fit ​​sliders 8 located inside the positioning components 9. The front of the guide frame 1 is provided with an adapter overlap frame 10. One end of the adapter overlap frame 10 is provided with a welding gun sleeve 11. The top of the adapter overlap frame 10 is rotatably snapped with a clamping component 12. The other end of the clamping component 12 is movably connected to two left and right rollers 13 located on the back of the guide frame 1. The rollers 13 roll in contact with the surface of the guide frame 1. The bottom of the adapter overlap frame 10 is movably connected to an adapter overlap piece 17 located directly in front of the rollers 13.

[0033] Depending on whether the welding surface is straight or curved, adjust the overall curvature of the guide frame 1, and then fix the bent guide frame 1 to one side of the seam to be welded using two fixing components 2. Then, insert the welding torch nozzle into the inside of the welding torch sleeve 11, as follows. Figure 1 and Figure 2 As shown, the clamping assembly 12, in cooperation with the adapter overlap frame 10, ensures that the roller 13 and the adapter overlap piece 17 can be clamped on both sides of the guide frame 1, thereby achieving the effect of the adapter overlap frame 10 restricting the welding torch sleeve 11 to move in accordance with the curvature of the guide frame 1. With the cooperation of the clamping assembly 12, roller 13 and adapter overlap piece 17, the adapter overlap frame 10 is always close to the side of the guide frame 1. As the welding work proceeds, the welder manipulates the welding torch to slide along the curvature of the guide frame 1, ensuring that the running trajectory of the welding torch nozzle inside the welding torch sleeve 11 can be adapted to the curvature of the weld seam under the restriction of the guide frame 1.

[0034] The curvature of the guide frame 1 connected end to end can be freely adjusted to adapt to the guidance of straight or curved weld seams. Due to the mutual meshing of the locking teeth 4 and the positioning teeth 6, the adjacent guide frames 1 are prevented from bending arbitrarily under the constraints of the rotating shaft 7, the snap-fit ​​slider 8 and the positioning component 9. This ensures that the overall curvature of the guide frame 1 can be fixed after adjustment. Furthermore, the two fixing components 2 can be used to adapt it to one side of the weld seam to facilitate the continuous movement of the welding torch.

[0035] like Figure 9 As shown, each of the two fixed components 2 includes a connecting shaft 21. The opposing surfaces of the two connecting shafts 21 are fixedly connected to the opposing back surfaces of the two guide frames 1 located at both ends. The other end of the connecting shaft 21 is rotatably sleeved with a connecting seat 22, which contacts the guide frame 1.

[0036] By connecting shaft 21, the guide frame 1 can be rotated relative to the two fixed components 2, thereby adjusting the angle of the bending plane of the guide frame 1 and adapting the bending plane of the guide frame 1 to the curved weld seam parallel to the working surface and the curved weld seam perpendicular to the working surface.

[0037] like Figure 9 As shown, a limiting groove 23 is provided at the bottom of the connecting seat 22. A magnet block 24 is slidably engaged inside the limiting groove 23. A lead screw 25 is threaded inside the magnet block 24. A first anti-detachment post 26 is fixedly connected to the top of the lead screw 25 and is rotatably engaged inside the connecting seat 22. The top of the first anti-detachment post 26 extends to the top of the connecting seat 22 and is fixedly connected to a knob 27.

[0038] Rotating the knob 27 allows the magnet block 24 to move through the first anti-detachment column 26 and the lead screw 25 under the restriction of the limiting groove 23, so that it moves up and down along the inside of the limiting groove 23, thereby achieving the strong adsorption between the magnet block 24 and the working surface steel plate, so as to facilitate the disassembly of the entire equipment.

[0039] like Figure 9 As shown, the positioning component 9 includes two snap-fit ​​grooves 91 opened at the top and bottom of the guide frame 1. The snap-fit ​​grooves 91 are connected to the insertion groove 3. The snap-fit ​​slider 8 is slidably snapped into the inside of the snap-fit ​​grooves 91. The inside of the guide frame 1 is provided with two positioning grooves 92 located on the front and rear sides of the snap-fit ​​grooves 91. The inside of the positioning grooves 92 is slidably snapped into two positioning sliders 93 located on the front and rear sides of the snap-fit ​​slider 8. The positioning sliders 93 are fixedly connected to the snap-fit ​​slider 8. The inside of the positioning grooves 92 is provided with positioning springs 94. The two ends of the positioning springs 94 are respectively connected to the positioning sliders 93 and the inner walls of the positioning grooves 92.

[0040] The movement of the snap-fit ​​slider 8 can be restricted by the snap-fit ​​groove 91, so as to ensure that the plug plate 5 can rotate along the inside of the plug groove 3 when the two adjacent guide frames 1 rotate relative to each other with the snap-fit ​​slider 8 engaged. At the same time, it can also ensure that the plug plate 5 will not completely detach from the plug groove 3.

[0041] like Figure 6 As shown, the cross-section of the inner cavity of the welding torch sleeve 11 is trapezoidal, the welding torch sleeve 11 is a non-closed-loop structure, and the inner diameter of the welding torch sleeve 11 is matched with the outer diameter of the welding torch nozzle.

[0042] The welding gun sleeve 11 allows operators to easily insert the welding gun nozzle and connect it to the matching lap bracket 10. At the same time, the non-closed loop area on the side of the welding gun sleeve 11 prevents the welding gun nozzle from being obstructed, allowing operators to directly observe the weld seam during welding.

[0043] like Figure 2 , 3As shown in Figure 10, a connecting plate 14 is provided at the top of the other end of the adapter lap bracket 10. The top of the adapter lap bracket 10 is provided with two left and right insertion slots 18 located at the bottom of the connecting plate 14. The bottom of the connecting plate 14 is connected with two left and right protective plates 15. The bottom of the protective plates 15 passes through the insertion slots 18 and extends to the bottom of the adapter lap bracket 10. The opposite ends of the two protective plates 15 have the same size, the opposite ends of the two protective plates 15 have different sizes and are inserted into each other. The insertion ends of the two protective plates 15 do not contact each other, and the size of the protective plate 15 on the side away from the welding gun sleeve 11 is larger than the size of the protective plate 15 on the side closer to the welding gun sleeve 11. The top of the adapter lap bracket 10 is provided with a fixing hole 19 located inside the insertion slots 18. Several elastic metal wires 16 located inside the two protective plates 15 are inserted into the fixing hole 19.

[0044] First, the elastic metal wire 16 can be used to clean both sides and the inside of the weld to prevent dust from affecting the weld's strength. The connecting plate 14 and the fixing hole 19 can facilitate the injection of hot air into the bottom of the adapter lap bracket 10 and between the two plug plates 5. Then, under the action of the elastic metal wire 16, the airflow inside and around the weld is heated to achieve the effect of preheating the weld.

[0045] like Figure 7 As shown, the adapter lap joint 17 includes an lap roller sleeve 171 that rolls in contact with the front of the guide frame 1. The lap roller sleeve 171 is movably fitted with two movable plates 172, one above the other. The bottom of the lower movable plate 172 is connected to a first clamping plate 173 that extends to the bottom of the guide frame 1, and the top of the upper movable plate 172 is connected to a second clamping plate 174 that extends to the top of the guide frame 1.

[0046] The clamping assembly 12 and the adapter overlap bracket 10 can tighten the roller shaft 13 and the overlap roller shaft sleeve 171 so that they can clamp the guide frame 1, thereby ensuring that the adapter overlap bracket 10 and the welding gun sleeve 11 are as close as possible to the guide frame 1 to achieve a more precise guiding effect.

[0047] like Figure 7 As shown, the second clamping plate 174 is rotatably snapped into the interior of the adapter overlap frame 10. The interior of the overlap roller bushing 171 is provided with two clamping springs 175 located on the outside of the first clamping plate 173 and the second clamping plate 174. The two ends of the clamping springs 175 are respectively connected to the movable plate 172 and the inner wall of the overlap roller bushing 171.

[0048] With the cooperation of the clamping spring 175 and the movable plate 172, the first clamping plate 173 and the second clamping plate 174 can clamp the upper and lower sides of the guide frame 1, preventing the fitting overlap frame 10 and the welding gun sleeve 11 from being far away from the weld. At the same time, due to the cooperation of the movable plate 172 and the clamping spring 175, the distance between the first clamping plate 173 and the second clamping plate 174 can also be adjusted to make it suitable for clamping the guide frame 1 to avoid parts with different thicknesses.

[0049] like Figure 7 As shown, the clamping assembly 12 includes a connecting sleeve rod 121 rotatably connected to the top of the adapter overlap frame 10 and directly above the adapter overlap piece 17. A second anti-detachment post 123 is movably sleeved inside the connecting sleeve rod 121. A connecting rod 124 is fixedly connected to the side of the second anti-detachment post 123 near the roller shaft 13. The other end of the connecting rod 124 extends to the outside of the connecting sleeve rod 121 and is fixedly connected to a mounting base 122. The bottom of the mounting base 122 is movably connected to the two roller shafts 13.

[0050] The clamping assembly 12 can make the roller 13 stick to the guide frame 1 under the elastic force of the return spring 125. At the same time, since the connecting axis of the clamping assembly 12 and the adapter overlap frame 10 and the connecting axis of the adapter overlap piece 17 and the adapter overlap frame 10 are coincident, the adjustment of the welding gun sleeve 11 and the rotation of the adapter overlap frame 10 are not restricted by the clamping assembly 12.

[0051] Working principle and usage process:

[0052] According to the requirements of the welding surface being straight or curved, adjust the curvature of the guide frame 1 as a whole, and then fix the bent guide frame 1 as a whole to one side of the seam to be welded by two fixing components 2. Then, insert the welding torch nozzle into the inside of the welding torch sleeve 11. With the cooperation of the clamping component 12, roller 13 and adapter lap joint 17, the adapter lap joint 10 is always close to the side of the guide frame 1 and slides along the curvature of the guide frame 1 as much as possible to ensure that the running trajectory of the welding torch nozzle inside the welding torch sleeve 11 can be adapted to the curvature of the weld seam under the restriction of the guide frame 1. Then, turn on the air pump to let the hot air flow through the connecting plate 14 and the fixing hole 19 into the inside of the protective plate 15 and heat the elastic metal wire 16. Finally, turn on the welding equipment to perform continuous welding.

[0053] Since the adapter lap bracket 10 can rotate within a limited range within the limitation of the adapter lap piece 17, it ensures that while the welding gun sleeve 11 moves along one side of the guide frame 1 through the adapter lap bracket 10, it can also move slightly relative to the bending trajectory of the guide frame 1 to ensure a smoother welding transition for non-smooth welds. At the same time, the length of the guide frame 1 itself and its sections within the unit total welding length range can be adjusted to increase the degree of smooth welding transition.

[0054] The connecting shaft 21 ensures that the guide frame 1 can rotate relative to the two fixed components 2, thereby ensuring that the curvature of the guide frame 1 can be adapted to the curved weld seam parallel to the working surface, and also to the curved weld seam perpendicular to the working surface, making it more suitable for the assembly and welding of curved ship cabin steel plates.

[0055] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
