Description

Technical Field

[0001] This invention relates to the field of welding technology, and more particularly to welding auxiliary tooling. Background Technology

[0002] During the shipbuilding phase, the welding process of steel plates can cause certain welding deformation after the welding heat is input, which can affect the subsequent assembly accuracy.

[0003] To address the aforementioned issues, traditional solutions typically involve installing temporary reinforcing bars on the steel plate to be welded via intermittent welding. However, setting up temporary reinforcing bars requires steps such as installation, welding, dismantling, and grinding, resulting in low efficiency.

[0004] To address the aforementioned issues, existing technology provides a welding auxiliary fixture that incorporates two magnetically reinforced rows to strengthen the steel plate to be welded. The magnetic attraction facilitates installation and disassembly. Furthermore, to prevent magnetic attenuation at high temperatures, a cooling box is included to reduce the temperature of the magnetically reinforced rows. However, the existing fixture suffers from the problem that it requires both the magnetically reinforced rows and the cooling box to be installed simultaneously, resulting in a large space occupation and a complex structure. Summary of the Invention

[0005] According to one aspect of the present invention, the present invention provides welding auxiliary tooling to solve the problem that the welding auxiliary tooling in the prior art requires the simultaneous installation of a magnetically suction-reinforced rack and a cooling box, which occupies a large space and has a complex structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A welding auxiliary fixture includes a cooling assembly for mounting on the workpiece to be welded. The cooling assembly comprises multiple cooling chambers connected in sequence, each of which is movable relative to its adjacent cooling chamber along a first plane. Each cooling chamber has a liquid storage chamber for holding a cooling medium. The cooling chamber has a working wall with a surface parallel to the first plane. The surface of the working wall is able to fit against the workpiece to be welded, so that the cooling medium in the liquid storage chamber exchanges heat with the workpiece.

[0008] As a preferred option for welding auxiliary tooling, a rotating shaft is provided between any two adjacent cooling boxes, and each cooling box can rotate relative to the rotating shaft adjacent to it.

[0009] As a preferred embodiment of welding auxiliary tooling, the cooling box also has a top wall disposed opposite to the working box wall, and a side wall located between the working box wall and the top wall. The side wall includes a first side wall, a second side wall disposed opposite to each other, and two third side walls located between the first side wall and the second side wall. The length of the first side wall is less than the length of the second side wall, and the rotating shaft is disposed on the third side wall.

[0010] As a preferred embodiment of the welding auxiliary tooling, it further includes a movable tooling for transporting the cooling component, the movable tooling comprising:

[0011] A base for support on the ground or on a ship's deck;

[0012] A core is disposed on the base, and the plurality of cooling boxes of the cooling assembly can be housed in the core so that the first sidewall contacts the outer wall of the core.

[0013] As a preferred option for welding auxiliary tooling, the core is provided with a limiting baffle. When the cooling box is housed within the core, the limiting baffle can abut against the working wall or the top wall of the cooling box.

[0014] As a preferred option for welding auxiliary tooling, the base is rotatably equipped with rollers, which are used for rolling support on the ground or ship deck.

[0015] As a preferred option for welding auxiliary tooling, the base is fixedly equipped with a handrail.

[0016] As a preferred embodiment of welding auxiliary tooling, the liquid storage chambers of any two adjacent cooling boxes are connected by a flexible hose. One of the two cooling boxes located at both ends is provided with an inlet communicating with the liquid storage chamber, and the other is provided with an outlet communicating with the liquid storage chamber.

[0017] As a preferred option for welding auxiliary tooling, the cooling box is equipped with an exhaust valve, which is used to discharge the gas in the liquid storage chamber.

[0018] As a preferred option for welding auxiliary tooling, the top of the cooling box is also provided with an exhaust pipe, and the end of the exhaust pipe away from the cooling box is connected to the exhaust valve.

[0019] The beneficial effects of this invention are:

[0020] This invention provides a welding auxiliary fixture, which includes a cooling assembly comprising multiple cooling boxes connected in sequence. Each cooling box is movable relative to its adjacent cooling box along a first plane, thereby changing the relative positions of the different cooling boxes along the first plane. Each cooling box has a liquid storage chamber for holding a cooling medium. The cooling box has a working wall with a surface parallel to the first plane, and the surface of the working wall can be in contact with the workpiece to be welded, allowing heat exchange between the cooling medium in the liquid storage chamber and the workpiece. The cooling box can be placed near the weld seam of the workpiece to be welded, thereby cooling the area near the weld seam during welding, preventing deformation of the workpiece due to heat. Furthermore, the cooling assembly is easy to remove after welding, and the welding auxiliary fixture has a simple structure. In addition, since each cooling box is movable relative to its adjacent cooling box along the first plane, multiple cooling boxes can be arranged along the first plane according to the shape of the weld seam to accommodate weld seams of different shapes.

[0035] 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.

[0039] During shipbuilding, the welding of steel plates during the welding process causes deformation, affecting subsequent assembly accuracy. Traditional methods typically involve intermittently welding temporary reinforcing bars onto the steel plates, but this is cumbersome and inefficient. To address these issues, existing technology provides a welding auxiliary fixture with two magnetic reinforcing bars to strengthen the steel plates, facilitating installation and removal. A cooling box is also included to prevent magnetic attenuation at high temperatures. However, this fixture requires both the magnetic reinforcing bars and the cooling box, resulting in significant space requirements and a complex structure.

[0040] To address the aforementioned issues, this embodiment provides welding auxiliary fixtures to solve the problems of existing welding auxiliary fixtures requiring simultaneous installation of magnetic reinforcement bars and cooling boxes, resulting in large space occupation and complex structures.

[0041] Reference Figures 1-4 The welding auxiliary fixture includes a cooling component 100, which is used to mount on the workpieces to be welded. Generally, there are two workpieces to be welded, and these two workpieces will be connected by welding. The cooling component 100 is mounted at the weld seam of one of the workpieces to be welded, or there are two cooling components 100, each mounted on one of the two workpieces to be welded and located on opposite sides of the weld seam. In this embodiment, the workpiece to be welded is a steel plate; in other embodiments, the workpiece to be welded can be other structures.

[0042] Continue to refer to Figures 1-4 The cooling assembly 100 includes multiple cooling boxes 1 connected in sequence. Each cooling box 1 can move relative to its adjacent cooling box 1 along a first plane, thereby changing the relative position between different cooling boxes 1 along the first plane. Each cooling box 1 has a liquid storage chamber for holding a cooling medium, typically water. Each cooling box 1 has a working wall 11, the surface of which is parallel to the first plane. The working wall 11 is made of a thermally conductive material and its surface can fit against the workpiece to be welded, allowing heat exchange between the cooling medium in the liquid storage chamber and the workpiece. The cooling box 1 can be placed near the weld seam of the workpiece to be welded, thereby cooling the area near the weld seam during welding, preventing deformation of the workpiece due to heat. Furthermore, after welding, the cooling assembly 100 is easy to remove, and the welding auxiliary tooling structure is simple. Furthermore, since any cooling box 1 can move relative to its adjacent cooling box 1 along the first plane, multiple cooling boxes 1 can be arranged along the first plane according to the shape of the weld to accommodate welds of different shapes.

[0043] Continue to refer to Figures 1-4In this embodiment, any cooling box 1 can rotate relative to its adjacent cooling box 1 along the first plane, thereby changing the extension shape of the cooling assembly 100 to adapt to welds of different shapes by rotating each cooling box 1. Specifically, a rotating shaft 2 is provided between any two adjacent cooling boxes 1, and any cooling box 1 can rotate relative to its adjacent rotating shaft 2.

[0044] Optionally, the cooling chamber 1 also has a top wall 12 opposite to the working chamber wall 11, and a side wall 13 located between the working chamber wall 11 and the top wall 12. The working chamber wall 11 is located at the bottom of the cooling chamber 1 to facilitate contact with the surface of the workpiece to be welded. The side wall 13 includes a first side wall 131, a second side wall 132 opposite to each other, and two third side walls 133 located between the first side wall 131 and the second side wall 132. The length of the first side wall 131 is less than the length of the second side wall 132, and the rotating shaft 2 is disposed on the third side wall 133. Figure 4 As shown, this arrangement allows multiple cooling boxes 1 to rotate sequentially, so that the first sidewalls 131 of the multiple cooling boxes 1 come closer to each other, making the overall structure of the multiple cooling boxes 1 ring-shaped, which facilitates storage.

[0045] Continue to refer to Figures 1-4 The liquid storage chambers of any two adjacent cooling boxes 1 are connected by a hose 3. One of the two cooling boxes 1 located at both ends is provided with an inlet 41 that communicates with the liquid storage chamber, and the other is provided with an outlet 42 that communicates with the liquid storage chamber. This allows the liquid storage chambers of each cooling box 1 to be interconnected, and the cooling medium can be input through the inlet 41 and output through the outlet 42 to achieve the circulation of the cooling medium and improve the cooling effect.

[0046] Continue to refer to Figures 1-4 The cooling medium in the storage chamber is prone to evaporation after being heated, forming high-temperature steam. In order to discharge this gas, the cooling box 1 is equipped with an exhaust valve 5. The exhaust valve 5 is used to discharge the gas in the storage chamber, thereby preventing the pressure in the storage chamber from becoming too high.

[0047] Continue to refer to Figures 1-4 The top of the cooling chamber 1 is also equipped with an exhaust pipe 51. Specifically, the exhaust pipe 51 is installed on the top wall 12 of the cooling chamber 1. The end of the exhaust pipe 51 away from the cooling chamber 1 is connected to an exhaust valve 5 to prevent the height of the exhaust valve 5 from being lower than the liquid level in the liquid storage chamber, so as to better discharge the gas in the liquid storage chamber. Optionally, the exhaust pipe 51 is L-shaped.

[0048] Reference Figures 1-5The welding auxiliary fixture also includes a movable fixture 200 for transporting the cooling component 100. The movable fixture 200 includes a base 6 and a core. The base 6 is used for support on the ground or ship deck. The core is disposed on the base 6, and multiple cooling boxes 1 of the cooling component 100 can be housed in the core so that the first sidewall 131 contacts the outer wall of the core. Specifically, the multiple cooling boxes 1 rotate sequentially, so that the first sidewalls 131 of the multiple cooling boxes 1 move closer to each other. Optionally, the core is rotatably disposed on the base 6 for easy operation by the user. Further optionally, the core is fixedly provided with a rotating handle 71 for easy operation by the user. In addition, when multiple cooling boxes 1 are housed in the core, the positions of the two cooling boxes 1 located at both ends cannot be fixed. They can be fixed by hand or by binding ropes.

[0049] Continue to refer to Figures 1-5 The core is equipped with a limiting baffle 7, which is located on either side of the core. When the cooling box 1 is housed within the core, the limiting baffle 7 abuts against the working wall 11 or top wall 12 of the cooling box 1, thereby limiting the cooling box 1 housed within the core and preventing it from falling off. Optionally, two limiting baffles 7 are provided, with the two limiting baffles 7 respectively located on both sides of the core.

[0050] Continue to refer to Figures 1-5 The base 6 is rotatably equipped with rollers 61, which are used to roll and support the base on the ground or ship deck, so that the user can push the base 6 to move it and complete the transportation of the cooling component 100. Optionally, the base 6 is fixedly equipped with a handle 62, so that the user can hold the base 6 and apply force to it.

[0051] The following combination Figures 1-5 This embodiment describes the usage of the welding auxiliary tooling:

[0052] First, the multiple cooling chambers 1 of the cooling assembly 100 are housed in the core of the movable fixture 200, and the cooling assembly 100 is transported to the position where the workpiece to be welded needs to be welded via the movable fixture 200. The multiple cooling chambers 1 are removed and placed near the weld seam so that the surface of the working wall 11 of the cooling chamber 1 is in contact with the workpiece to be welded, and cooling medium is introduced into the cooling chamber 1. Each cooling chamber 1 is rotated sequentially to change the extended shape of the cooling assembly 100 to match the shape of the weld seam. Welding is then performed. During the welding process, the cooling medium inside the cooling chamber 1 can exchange heat with the workpiece to be welded, cooling the area near the weld seam and preventing deformation of the workpiece due to heat.

[0053] 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.
