Technical Field

[0001] This utility model relates to the field of ship hull welding technology, and in particular to a ship hull welding and assembly tooling. Background Technology

[0002] Ships, or vessels, refer to any means of transportation that utilizes the buoyancy of water and relies on human power, sails, engines (such as steam engines, gas turbines, diesel engines, and nuclear power units) to move on water by pulling, pushing, rowing, or propelling propellers or high-pressure nozzles. In addition, civilian ships are generally called boats (anciently called zhulu), wheels (ships), or fang, while military ships are called warships (anciently called mengchong) or boats. Small boats are called sampans, boats, rafts, or zhou. They are collectively referred to as ships, vessels, or boats.

[0003] During the welding process of ship hulls, two welding plates are usually joined together. However, the existing technology does not have a device for joining welding plates together, which requires manual joining during the welding process and causes some trouble. Some devices that do have welding plate joining devices cannot adjust their height, thus reducing the overall adaptability and linkage of the device. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology. By continuously moving two moving plates, two triangular blocks push the two welding plates of the hull to move, causing the two welding plates to bend and come into contact with each other, thereby achieving welding and closing, which brings convenience to people. The setting of two rollers protects the outer wall of the hull and avoids excessive friction that could damage the hull. Therefore, a hull welding and closing tooling is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hull welding and assembly fixture includes a base with a groove at its upper end. Two movable plates are slidably connected within the groove. Each movable plate has a movable frame slidably connected to its outer wall. Each movable frame has a triangular block on its opposite face. Each triangular block has a rotating groove on its inclined surface. A roller is rotatably connected within the rotating groove, with its outer wall located outside the rotating groove. A moving mechanism for moving the two movable plates is provided within the groove. Each movable frame has an adjustment mechanism at its upper end for adjusting its height.

[0007] Preferably, the moving mechanism includes a double-ended screw that is rotatably connected between the groove and the side wall of the base, the two ends of the double-ended screw having opposite thread directions, and the two moving plates are respectively located on the outer walls of the two ends of the double-ended screw and threadedly connected to them.

[0008] Preferably, the adjustment mechanism includes an internal threaded groove formed on the upper end of the movable plate, and a threaded rod is threadedly connected through the internal threaded groove. The threaded rod passes through the upper end of the movable frame and is rotatably connected to it.

[0009] Preferably, the upper end of the base is provided with two symmetrically arranged support plates, both of which are telescopic plates, and a rotating rod is rotatably connected between the two support plates. The outer wall of the rotating rod is provided with multiple circumferentially arranged limiting grooves.

[0010] Preferably, each of the two movable frame sidewalls is provided with a fixing block, and a sleeve is rotatably connected through the fixing block. The sleeve is sleeved on the outer wall of the rotating rod and slidably connected thereto. The inner wall of the sleeve is provided with multiple limiting blocks, and the multiple limiting blocks are respectively located in multiple limiting grooves and slidably connected thereto.

[0011] Preferably, the outer wall of the sleeve is provided with a worm gear, and the upper outer wall of the threaded rod is provided with a worm wheel, and the worm gear and the worm wheel cooperate with each other.

[0012] The beneficial effects of this utility model are:

[0013] 1. By continuously moving two movable plates, two triangular blocks push the two welding plates of the hull to move, causing the two welding plates to bend and come into contact with each other, thereby achieving welding and closing, which brings convenience to people. The setting of two rollers protects the outer wall of the hull and avoids excessive friction that could damage the hull.

[0014] 2. By rotating the worm gear, the threaded rod is driven to rotate. The threaded rod is connected to the internal thread groove, allowing it to move within the groove.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0022] Reference Figure 1-4 A hull welding and joining fixture includes a base 1 with a groove 2 at its upper end. Two movable plates 4 are slidably connected within the groove 2. Movable frames 5 are slidably connected to the outer walls of both movable plates 4. Triangular blocks 6 are provided on the opposite faces of the two movable frames 5. Rotating grooves 9 are provided on the inclined surfaces of the two triangular blocks 6. Rollers 10 are rotatably connected within the rotating grooves 9, with their outer walls located outside the rotating grooves 9. A moving mechanism for moving the two movable plates 4 is provided within the groove 2. The moving mechanism includes a double-ended screw 3 that is rotatably connected between the groove 2 and the side wall of the base 1. The threads at both ends of the double-ended screw 3 have opposite directions. The two movable plates 4 are located on the outer walls at both ends of the double-ended screw 3 and are threadedly connected to it. Through the continuous movement of the two movable plates 4, the two triangular blocks 6 push the two welding plates of the hull to move, causing the two welding plates to bend and come into contact with each other, thereby achieving welding and joining. This provides convenience for people. The two rollers 10 protect the outer wall of the hull and prevent excessive friction from damaging the hull.

[0023] Both movable frames 5 are provided with adjustment mechanisms at their upper ends for adjusting their height. The adjustment mechanism includes an internal threaded groove 12 opened at the upper end of the movable plate 4, and a threaded rod 13 is threadedly connected through the internal threaded groove 12. The threaded rod 13 passes through the upper end of the movable frame 5 and is rotatably connected to it.

[0024] The upper end of the base 1 is provided with two symmetrically arranged support plates 7. Both support plates 7 are telescopic plates. A rotating rod 11 is rotatably connected between the two support plates 7. Multiple circumferentially arranged limiting grooves 18 are opened on the outer wall of the rotating rod 11.

[0025] Both movable frames 5 have fixed blocks 16 on their side walls. A sleeve 15 is rotatably connected through the fixed block 16. The sleeve 15 is fitted onto the outer wall of the rotating rod 11 and is slidably connected to it. The inner wall of the sleeve 15 has multiple limiting blocks 19. The multiple limiting blocks 19 are located in multiple limiting grooves 18 and are slidably connected to them.

[0026] The outer wall of the sleeve 15 is provided with a worm 17, and the upper outer wall of the threaded rod 13 is provided with a worm wheel 14. The worm 17 and the worm wheel 14 cooperate. By rotating the worm wheel 14, the threaded rod 13 is driven to rotate. By utilizing the threaded connection between the threaded rod 13 and the inner thread groove 12, the threaded rod 13 moves within the inner thread groove 12. This movement of the threaded rod 13 drives the moving frame 5 to move, thereby achieving the effect of adjusting the height of the triangular block 6 and improving the adaptability of the device.

[0027] When using this utility model, during the assembly of the welded hull (since welding is an existing technology, its related structure is not described in detail in this drawing), the base 1 is placed on both sides of the hull, and the power motor 8 is started, causing the power motor 8 to drive the double-headed screw 3 to rotate. Utilizing the threaded connection between the movable plate 4 and the double-headed screw 3, and the opposite rotation of the threads at both ends of the double-headed screw 3, the two movable plates 4 move relative to each other within the groove 2. This causes the movable plates 4 to move relative to the movable frames 5, so that the triangular blocks 6 on the opposite surfaces of the two movable frames 5 contact the outer walls of the welded ends of the hull. As the two movable plates 4 continue to move, the two triangular blocks 6 push the two welded plates of the hull to move, causing the two welded plates to bend and contact each other, thereby achieving the welding assembly and providing convenience. The two rollers 10 are set to protect the outer wall of the hull and avoid excessive friction that could damage the hull.

[0028] When the closing height needs to be adjusted according to the actual situation, the rotating rod 11 is rotated. The cooperation of multiple limiting grooves 18 and limiting blocks 19 on the outer wall of the rotating rod 11 causes the rotating rod 11 to rotate, which in turn causes the sleeve 15 to rotate. This causes the worm 17 on the outer wall of the sleeve 15 to rotate. The cooperation of the worm 17 and the worm wheel 14 causes the worm wheel 14 to rotate, which in turn causes the threaded rod 13 to rotate. The threaded connection between the threaded rod 13 and the internal thread groove 12 causes the threaded rod 13 to move within the internal thread groove 12. This movement of the threaded rod 13 causes the moving frame 5 to move, thereby achieving the effect of adjusting the height of the triangular block 6 and improving the adaptability of the device. Furthermore, the telescopic setting of the support plate 7 and the setting of multiple limiting grooves 18 and limiting blocks 19 ensure that the two pairs of worms 17 and worm wheels 14 are always in a meshing state, improving the linkage of the device.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
