Description

Technical Field

[0001] The utility model belongs to the technical field of shipbuilding, and particularly relates to a welding tooling for curved panels in shipbuilding. Background Art

[0002] In the field of shipbuilding, the welding operation of curved panels generally relies on fixed support tooling to complete the positioning and clamping of plates.

[0003] For example, in the prior art with the publication number: CN221695746U and the name: A welding machine for curved panels in shipbuilding, similar to traditional tooling, it mostly uses prefabricated support plates and support blocks to support the curved panels. The distribution of its support points and the radius of curvature are solidified during manufacturing, resulting in the tooling system being only suitable for plates within a specific curvature range and not being convenient to appropriately adjust the support position according to curved panels with different curvatures. When welding the outer hull plates, bulkhead plates or deck members with different curvatures of a ship, it is necessary to redesign and manufacture special tooling for each surface parameter, resulting in problems such as extended production cycles and doubled tooling storage costs. Especially in the small and medium-sized shipyards with multi-variety and small-batch production, the non-value-added time caused by frequent tooling replacement can account for more than 30% of the total welding man-hours, seriously restricting the level of production flexibility. Summary of the Utility Model

[0004] In view of the above-mentioned disadvantages of the prior art, the purpose of the utility model is to provide a welding tooling for curved panels in shipbuilding, which is used to solve the problems in the prior art that the welding tooling for curved panels has poor adaptability and is not convenient to appropriately adjust the support position according to curved panels with different curvatures.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A welding tooling for curved panels in shipbuilding, including a tooling table. A window is penetrated through the middle of the tabletop of the tooling table. A lifting block is fixedly installed above the window. A clamping device is installed in the lifting block, and the clamping device is used to clamp and fix the butt ends of two curved panels. On the tabletop of the tooling table, with the lifting block as the symmetric center axis, H-shaped carriers are rotatably installed on both the left and right sides. The top ends of the H-shaped carriers are rotatably installed with supporting rollers, and connecting rods are fixedly installed in the H-shaped carriers. On the tabletop of the tooling table, two adapter seats A are rotatably installed symmetrically left and right with the lifting block as the axis. Hydraulic telescopic rods A are rotatably installed on one side of each adapter seat A close to the H-shaped carrier, and the ends of the hydraulic telescopic rods A far from the adapter seats A are rotatably connected to the corresponding connecting rods.

[0007] In the above technical solution, a chute is formed through the upper surface of the lifting block. The clamping device includes a hydraulic telescopic rod B, which is fixedly installed in the window, and an inverted T-shaped baffle is fixedly installed on the upper surface of the hydraulic telescopic rod B. The inverted T-shaped baffle is vertically slidably arranged in the chute. Locking frames are fixedly installed on both the left and right sides of the inverted T-shaped baffle, and the two locking frames are respectively located on the left and right sides of the lifting block.

[0008] In the above technical solution, mounting grooves are formed on both the left and right surfaces of the inverted T-shaped baffle, and the locking frame is detachably installed in the corresponding mounting groove through bolts.

[0009] In the above technical solution, a support frame is fixedly installed on the lower surface of the tooling table. The support frame is located below the window, and a fixed connection is established between the support frame and the lower surface of the hydraulic telescopic rod B.

[0010] In the above technical solution, two position-adjustable flange limit rings are slidably sleeved on the outer peripheral surface of the supporting roller.

[0011] In the above technical solution, locking bolts are screwed through the outer surfaces of the flange limit rings, and the lower surfaces of the locking bolts are in contact with the outer surface of the supporting roller.

[0012] A shipbuilding curved panel welding tooling of the present utility model has the following beneficial effects compared with the prior art:

[0013] By providing a lifting block and two H-shaped carriers driven by hydraulic telescopic rods A to adjust the support height respectively, when the welding ends of two curved panels are butted on the lifting block, the top height of the H-shaped carrier can be adjusted to adapt to the curvature of the curved panel to achieve the support purpose, improving the poor adaptability of the curved panel welding tooling and facilitating the appropriate adjustment of the support position according to curved panels with different curvatures.

[0014] In addition, by sleeving and installing two position-adjustable flange limit rings on the outer surface of the supporting roller of the present utility model, the positions of the four flange limit rings can be adjusted to the corresponding points to guide during the butting of the curved panels, ensuring the accuracy during the butting of the two curved panels and improving the welding quality.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In this embodiment, the front, rear, left, right, top and bottom are represented by Figure 1 Describes the datum surface. Figures 1-6 , the utility model provides a technical solution:

[0024] A shipbuilding curved panel welding tool, comprising a tooling table 1, a window 11 is opened through the middle of the tabletop of the tooling table 1, a lifting block 12 is fixedly installed above the window 11, the lifting block 12 is a hard metal block, a clamping device 2 is installed in the lifting block 12, the lifting block 12 is a hard metal block, when the clamping device 2 is working, the lifting block 12 is guaranteed not to be easily deformed, the clamping device 2 is used to clamp and fix the butt ends of two curved panels, the tabletop of the tooling table 1 is fixed with the lifting block 12 as the opposite The center axis is called the center axis, and H-shaped carriers 3 are rotatably installed on both sides. The top of the H-shaped carrier 3 is rotatably installed with supporting rollers 4, and connecting rods 31 are fixedly installed in the H-shaped carrier 3. Two adapters A5 are rotatably installed on the table top of the workbench 1 with the lifting block 12 as the central axis, and a hydraulic telescopic rod A51 is rotatably installed on the side of the adapter A5 close to the H-shaped carrier 3. The end of the hydraulic telescopic rod A51 away from the adapter A5 is rotatably connected to the corresponding connecting rod 31.

[0025] Combination Figure 3 , Figure 5 andFigure 6 As shown, during actual use, first, the docking ends of the two curved panels are jointly docked to the lifting block 12. Immediately afterwards, the outer ends of the two curved panels are respectively placed on the supporting rollers 4. Subsequently, by controlling the extension or contraction of the hydraulic telescopic rod A51 on the corresponding side, the H-shaped carrier 3 is driven to flip by means of the connecting rod 31. When it is flipped until the supporting roller 4 is completely attached to the lower surface of the curved panel, observe the docking position of the two curved panels. If the docking surface is completely attached, it indicates that the lifting position at this time is the optimal state, and then stop the operation of the hydraulic telescopic rod A51, and rely on the supporting roller 4 and the H-shaped carrier 3 to form a stable support for the curved panel. Thereafter, use the clamping device 2 to clamp and fix the docking end of the curved panel on the lifting block 12, and then the welding operation can be carried out. Compared with the traditional welding tooling for curved panels, this tooling effectively improves the problem of poor adaptability of the welding tooling for curved panels and can flexibly and appropriately adjust the supporting position according to curved panels with different curvatures.

[0026] Combined with Figure 1 , Figure 2 and Figure 4 As shown, a chute 121 is penetrated and opened on the upper surface of the lifting block 12. The clamping device 2 includes a hydraulic telescopic rod B21. The hydraulic telescopic rod B21 is fixedly installed in the window 11, and an inverted T-shaped baffle 22 is fixedly installed on the upper surface of the hydraulic telescopic rod B21. The inverted T-shaped baffle 22 is vertically slidably arranged in the chute 121. Locking frames 23 are fixedly installed on both the left and right sides of the inverted T-shaped baffle 22. The two locking frames 23 are respectively located on the left and right sides of the lifting block 12;

[0027] When the hydraulic telescopic rod B21 extends or contracts, it can drive the inverted T-shaped baffle 22 and the locking frame 23 to move up or down simultaneously. When placing the docking end of the curved panel on the upper surface of the lifting block 12, it is necessary to first drive the inverted T-shaped baffle 22 out of the chute 121 by means of the drive of the hydraulic telescopic rod B21. By using the shielding of the inverted T-shaped baffle 22, it can prevent the curved panel from sliding off the lifting block 12 and play a role in pre-blocking the placement. When the placement is completed, use the drive of the hydraulic telescopic rod B21 again to move the inverted T-shaped baffle 22 down into the chute 121 and drive the locking frame 23 to move down. When the inverted T-shaped baffle 22 is completely received in the chute 121, there is still a certain gap between the locking frame 23 and the curved panel. At this time, two people operate manually and push towards the welding ends of the two curved panels to complete the docking work of the two curved panels. Finally, use the hydraulic telescopic rod B21 to drive the locking frame 23 to move down and fit with the curved panel to complete the fixation work before welding.

[0028] Combined with Figure 4As shown in the figure, mounting grooves 221 are formed on both the left and right surfaces of the inverted T-shaped baffle 22. The locking frame 23 is detachably mounted in the corresponding mounting groove 221 by bolts. Locking frames 23 with different height specifications can be selected and replaced according to the thickness of the curved panel.

[0029] During operation, when processing curved panels of different thicknesses, the locking frame 23 can be separated from the inverted T-shaped baffle 22 by removing the connecting bolts in the mounting groove 221, and then a locking frame 23 suitable for the current panel thickness can be replaced and fixed. Through the standardized notch design of the mounting groove 221, this structure realizes the rapid disassembly and replacement of the locking frame 23, effectively solving the problem of limited application range caused by the non-adjustable locking height of traditional fixing devices.

[0030] Combined Figure 2 As shown in the figure, a support frame 13 is fixedly installed on the lower surface of the tooling table 1. The support frame 13 is located below the window 11, and is fixedly connected to the lower surface of the hydraulic telescopic rod B21 by bolts. The hydraulic telescopic rod B21 is fixedly installed in the window 11 by being fixedly connected to the support frame 13.

[0031] To ensure the accurate alignment of the edges when two curved panels are butted, two position-adjustable flange limit rings 6 are slidably sleeved on the outer peripheral surface of the supporting roller 4, and locking bolts 61 are screwed through the outer surfaces of the flange limit rings 6. When the lower surface of the locking bolt 61 fits the outer surface of the supporting roller 4, it indicates that the position of the flange limit ring 6 is fixed.

[0032] Before use, first adjust the two rear flange limit rings 6 to be aligned left and right, and then adjust the two front flange limit rings 6 according to the width of the curved panel so that the distance between the front and rear flange limit rings 6 is the same as the width of the curved panel, and then the curved panel can be placed. One end of the curved panel is placed on the lifting block 12, and the other end is placed on the supporting roller 4 and located between the front and rear flange limit rings 6. In this way, the positioning function of the flange limit ring 6 can be used to align the edges of the two curved panels after butting, effectively ensuring the butting accuracy and thus guaranteeing the welding quality.
