Abstract
Description
Technical Field
[0001] This invention relates to the field of welding technology, and in particular to auxiliary tooling for welding weatherproof doors. Background Technology
[0002] Weatherproof doors are installed on the hull panels of ships to provide protection against wind and rain. During the shipbuilding phase, these doors need to be welded to the hull. Because the hull panels are relatively thin, welding results in significant deformation. Currently, temporary reinforcing bars are typically installed around the perimeter by spot welding to enhance the structural strength of the hull panels and reduce deformation. However, these temporary reinforcing bars need to be removed and ground down after the weatherproof doors are welded, a time-consuming and labor-intensive process.
[0003] To address this, existing technologies employ magnetic reinforcement bars to attach them to the ship's hull panels using magnetic force, facilitating assembly and disassembly. However, the magnetic force of these reinforcement bars weakens significantly at high temperatures, rendering them insufficient for the high-temperature welding requirements of steel plates. Summary of the Invention
[0004] According to one aspect of the present invention, the present invention provides a welding auxiliary fixture for weatherproof doors to solve the problem that the magnetic force of the magnetic reinforcement bar in the prior art is significantly attenuated at high temperatures, resulting in the magnetic force not meeting the requirements for high-temperature welding of steel plates.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A welding auxiliary fixture for weatherproof doors is used to install on a ship's hull plating, the hull plating having openings for installing weatherproof doors. It includes a reinforcing assembly comprising multiple frames that can conform to the hull plating, the multiple frames being sequentially connected end-to-end and surrounding the openings. Two reinforcing assemblies are provided, each located on one side of the hull plating. Each of the multiple frames of the two reinforcing assemblies is equipped with a magnet assembly, the magnet assemblies of the two reinforcing assemblies attracting each other to clamp the hull plating between the two reinforcing assemblies. Each of the multiple frames of the two reinforcing assemblies is also equipped with a cooling assembly, the cooling assembly capable of exchanging heat with the magnet assemblies to reduce their temperature.
[0007] As a preferred embodiment of the auxiliary tooling for welding weatherproof doors, the frame has a U-shaped cross-section, a mounting groove, and includes two opposing frame sidewalls and a frame bottom wall located between the two frame sidewalls. The frame bottom wall can fit into the hull panel, and the magnet assembly is disposed in the mounting groove.
[0008] As a preferred embodiment of the welding auxiliary tooling for weatherproof doors, the bottom wall of the frame is provided with multiple mounting holes that communicate with the mounting groove, and the magnet assembly includes multiple magnets, which are arranged one-to-one in the multiple mounting holes.
[0009] As a preferred embodiment of the auxiliary tooling for welding weatherproof doors, the frame is fixedly provided with multiple mounting structures, each of which corresponds to a magnet, and the magnet passes through the mounting hole and is detachably connected to the mounting structure.
[0010] As a preferred embodiment of the auxiliary tooling for welding weatherproof doors, the cooling assembly includes two cooling boxes, which are respectively disposed on the two side walls of the frame.
[0011] As a preferred embodiment of the auxiliary tooling for welding weatherproof doors, the cooling box has a cooling cavity for filling with a cooling medium.

[0017] This invention provides auxiliary tooling for welding weatherproof doors, including reinforcing components. Each reinforcing component comprises multiple frames that can conform to the hull plating. These frames are connected end-to-end and surround an opening. Two reinforcing components are provided, one on each side of the hull plating. Magnet components are installed on each frame of the two reinforcing components. These magnet components attract each other, clamping the hull plating between the two components. This strengthens the structure around the opening in the hull plating, preventing excessive deformation during welding.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

They are used only for ease of description and simplification of operation, 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.

[0033] During shipbuilding, weatherproof doors need to be welded to the hull. Due to the thinness of the hull panels, welding results in significant deformation. Currently, temporary reinforcing bars are typically installed around the perimeter by spot welding to enhance the structural strength of the hull panels and reduce deformation. However, these temporary reinforcing bars need to be removed and ground down after the weatherproof doors are welded. Existing technology addresses this by using magnetic reinforcing bars, which are installed to the hull panels using magnetic force for easy installation and removal. However, the magnetic force of these reinforcing bars weakens significantly at high temperatures, rendering them insufficient for the high-temperature welding requirements of steel plates.
[0034] To address the aforementioned issues, this embodiment provides an auxiliary tooling for welding weatherproof doors, which solves the problem that the magnetic force of the magnetic reinforcement bar in the prior art significantly decreases at high temperatures, resulting in the magnetic force failing to meet the requirements for high-temperature welding of steel plates. It can be used in the field of welding technology, specifically for welding ship hull panels and weatherproof doors.
[0035] Reference Figures 1-4A welding auxiliary fixture for weatherproof doors is used to install on the hull plating. The hull plating has openings for installing weatherproof doors, which are welded to the wall of the openings to seal them. The welding auxiliary fixture includes a reinforcing component 10, which includes multiple frames 1 that can fit against the hull plating. The multiple frames 1 are connected end to end and surround the openings. In this embodiment, the overall structure of the multiple frames 1 of the reinforcing component 10 is rectangular, and the reinforcing component 10 includes four frames 1. Two reinforcing components 10 are provided, one on each side of the hull plating. Each frame 1 of the two reinforcing components 10 is equipped with a magnet component 2. The magnet components 2 of the two reinforcing components 10 can attract each other, so that the two reinforcing components 10 clamp the hull plating, thereby strengthening the structural strength around the opening of the hull plating and preventing excessive deformation during the welding of the weatherproof door. Each of the multiple frames 1 of the two reinforcing components 10 is equipped with a cooling component 3. The cooling component 3 can exchange heat with the magnet component 2 to reduce the temperature of the magnet component 2, thereby preventing the magnetic force of the magnet component 2 from decaying at high temperatures, so that the two reinforcing components 10 can be stably installed on the hull wall.
[0036] Continue to refer to Figures 1-4 The frame 1 has a U-shaped cross-section and a mounting groove 11. It includes two opposing frame sidewalls 12 and a frame bottom wall 13 located between the two frame sidewalls 12. The frame bottom wall 13 can fit against the hull panel. The magnet assembly 2 is disposed within the mounting groove 11. This arrangement protects the magnet assembly 2 from external impacts through the frame sidewalls 12 and the frame bottom wall 13 of the mounting groove 11.
[0037] Continue to refer to Figures 1-4 The bottom wall 13 of the frame has multiple mounting holes that communicate with the mounting groove 11. The magnet assembly 2 includes multiple magnets 21, which are arranged one-to-one in the mounting holes. The mounting holes allow the magnets 21 to be stably installed on the frame 1, while also facilitating disassembly and assembly.
[0038] Continue to refer to Figures 1-4The frame 1 is fixedly provided with multiple mounting structures 14, each corresponding to a magnet 21. The magnet 21 passes through mounting holes and is detachably connected to the mounting structure 14, thus enabling the installation and removal of the magnet 21 relative to the frame 1. Optionally, the mounting structure 14 includes two intersecting mounting strips 141. Both ends of the two mounting strips 141 are fixed to the bottom wall 13 of the frame 1, and the middle portions of the two mounting strips 141 are connected to each other. After the magnet 21 passes through the mounting hole, it can be limited by the two mounting strips 141, ensuring that the magnet 21 can only enter and exit the mounting hole from the side of the bottom wall 13 away from the mounting strips 141. The mounting structure 14 also includes a first bolt 142, which passes through the mounting strips 141 and is threadedly connected to the magnet 21, thus detachably connecting the magnet 21 to the mounting structure 14.
[0039] Continue to refer to Figures 1-4 The cooling assembly 3 includes two cooling boxes 31, which are respectively disposed on the two frame side walls 12 of the frame 1, so that the two cooling boxes 31 can exchange heat with the two frame side walls 12 respectively, thereby reducing the temperature of the two frame side walls 12 and thus reducing the temperature of the magnet 21 installed in the mounting groove 11. Optionally, the cooling assembly 3 also includes two mounting plates 32 connected to the cooling boxes 31, which are connected to the two cooling boxes 31 one by one. The mounting plates 32 are used to connect to the frame side walls 12 of the frame 1. Specifically, the two mounting plates 32 are respectively disposed on the outside of the two frame side walls 12, and are detachably connected by a second bolt 321 passing through one mounting plate 32, one frame side wall 12, the other frame side wall 12, and the other mounting plate 32 in sequence.
[0040] Continue to refer to Figures 1-4 The cooling chamber 31 has a cooling cavity, which is filled with a cooling medium, thereby exchanging heat with the frame sidewall 12 through the cooling medium. The cooling medium can be a fluid such as cold water.
[0041] Continue to refer to Figures 1-4 The cooling chamber 31 also has an injection port for supplying cooling medium into the cooling chamber and an outlet port for discharging cooling medium from the cooling chamber, facilitating the inflow and outflow of the cooling medium. Optionally, since the cooling medium is generally water, which easily turns into gas when heated, an exhaust valve is provided in the cooling chamber 31 to prevent excessive gas pressure inside the cooling chamber. The exhaust valve is used to discharge gas from the cooling chamber. In addition, a circulation pipeline can be provided through the injection port and the outlet port to enhance the continuous heat exchange effect.
[0042] Continue to refer to Figures 1-4Both ends of the frame 1 are fixedly provided with connectors 4. The two connectors 4 of two adjacent frames 1 are detachably connected. Since the overall structure of the multiple frames 1 of the reinforcing component 10 in this embodiment is rectangular, the included angle between two adjacent frames 1 is 90°. Therefore, the included angle between the connector 4 and the frame 1 is 135°, so as to facilitate the connection between the two connectors 4 of two adjacent frames 1. Optionally, the two connectors 4 of two adjacent frames 1 are connected by a third bolt 41, specifically, the third bolt 41 passes through the two connectors 4 in sequence.
[0043] Continue to refer to Figures 1-4 A handle 5 is provided at either end of the frame 1. The handle 5 can be used by the user to move the reinforcing component 10 or adjust its position. Furthermore, the handle 5 at either end of the frame 1 allows the user to easily lift one end of the frame 1 after the weatherproof door is welded, thus lifting a portion of the reinforcing component 10 relative to the hull panel. At this time, the magnetic force between the two magnetic components 2 decreases, allowing the user to operate the handles 5 of the other frame 1 to remove the reinforcing component 10 entirely from the hull panel. This arrangement facilitates the user's removal of the reinforcing component 10 from the hull panel, saving effort. In this embodiment, the frame 1 has two handles 5, located at both ends of the frame 1. Optionally, the handles 5 are T-shaped for easier user operation.
[0044] Continue to refer to Figures 1-4 The frame 1 is provided with a lifting member 6, which has a lifting hole 61 for installing a hook, so that the hook of the lifting equipment can be used to lift the reinforcing component 10.
[0045] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
