Description

Technical Field

[0001] This application relates to the field of shipbuilding technology, and in particular to a method and apparatus for preventing deformation during welding of aluminum alloy structures. Background Technology

[0002] In the construction of aluminum alloy ships, especially during the assembly and welding stages of sections and components, it is usually necessary to fix and reinforce the profiles to prevent them from tilting or deforming to one side. The traditional method is to install diagonal braces between the profiles and stiffened plates for fixation. However, this method not only increases the number of welding feet during construction but also increases the workload of subsequent welding and grinding. In addition, the diagonal braces have a limited number of uses, often becoming unusable after a few applications, resulting in low material reuse rates. Furthermore, because aluminum alloy plates are relatively thin, forcefully removing the diagonal braces can easily cause deformation of the plate and damage to the base material. Summary of the Invention

[0003] To address the aforementioned problems, this application proposes a method for preventing deformation during aluminum alloy welding and a corresponding tooling device.

[0004] This invention provides an anti-deformation device for welding aluminum alloy structures, the device comprising: a figure-eight clamping plate, a ratchet rail, a connecting shackle, and a clamping plate assembly;

[0005] The seven-character card plate includes a snap-fit ​​part and a clamping part. One end of the clamping part is connected to one end of the snap-fit ​​part, and the other end of the clamping part has a protrusion. A round hole is opened at the other end of the snap-fit ​​part, and a card slot hole is opened between the two ends of the snap-fit ​​part.

[0006] The two seven-shaped clamping plates are divided into left and right parts, arranged in a mirror symmetrical manner. The clamping slots of the two seven-shaped clamping plates overlap at least partially and are connected by bolts to form a "door" shaped structure. The round holes of each of the two seven-shaped clamping plates are exposed on the clamping part side of the other. The clamping parts of the two seven-shaped clamping plates correspond to each other. The two protrusions correspond to each other and cooperate with the clamping part and the snap-fit ​​part to form a limiting groove. The limiting groove is used to snap-fit ​​the welded structural profile.

[0007] The clamping plate assembly is used to clamp the stiffened extruded profile adjacent to the structural profile to be welded;

[0008] The screws at both ends of the ratchet rail are detachably connected to the round hole of the seven-shaped card plate and the card plate assembly via connecting shackles.

[0009] In some embodiments, the clamping plate assembly includes clamping plates adapted to different stiffened extruded profiles and bolt-type clamping plates.

[0010] In some embodiments, the device further includes: a shackle extension connected to the screws at both ends of the ratchet rail to accommodate different length requirements.

[0011] This invention provides a method for preventing deformation during welding of aluminum alloy structures, using the apparatus described in any of the above embodiments. The method includes:

[0012] Two seven-shaped plates are connected by bolts and assembled into a "door" shaped structure;

[0013] Connect one end of the ratchet rail to the corresponding round hole at the end of the figure-eight plate by connecting the shackle;

[0014] Connect the other end of the ratchet rail to the pallet assembly by connecting the shackle;

[0015] The "door" shaped structure is clamped onto the top of the profile to be welded, so that the clamping plate assembly is clamped and fixed to the extruded profile with stiffening plate;

[0016] Operate the ratchet rail tightening device to pull the plate seam closed and keep it in a fixed state. After welding is completed, loosen the ratchet rail and disassemble the device.

[0017] In some embodiments, the method further includes:

[0018] Add shackle extensions to both ends of the ratchet screw, adjust the device to fit the dimensions, and then fix it.

[0019] In some embodiments, the method further includes selecting a suitable clamping plate assembly based on the type of ribbed extruded profile.

[0020] The beneficial effects of the above embodiments include:

[0021] This device can be quickly disassembled and installed and is reusable, solving the problem that diagonal braces had to be replaced after a few uses, improving material reuse rate and reducing waste.

[0022] This device uses a screw and ratchet to easily close the board seams without the need for additional assembly feet, greatly reducing the workload of workers and improving work efficiency.

[0023] This device features a simple structure, easy manufacturing, compatibility with both steel and aluminum ships, and high safety and reliability. It is suitable for widespread application in shipbuilding.

[0024] The clamping device of this equipment is a replaceable part, and different sizes of clamping plates can be replaced according to different ship plates, making it flexible and versatile. At the same time, the device can be adjusted to adapt to different sizes of profiles by adding shackles at both ends of the screw according to the size of the structural profile.

[0025] For structural components with angular requirements, this device can effectively guarantee the structural accuracy of the angle, thus ensuring product quality. Attached Figure Description

The clamping parts 12 of the two figure-seven clamping plates 1 correspond to each other, and the two protrusions 16 correspond to each other and cooperate with the clamping part 12 and the snap-fit ​​part 11 to form a limiting groove. The limiting groove is used to snap-fit ​​the welding structural profile 9.
