Description

Technical Field

[0001] This invention relates to the field of shipbuilding tooling, and in particular to a modular tooling for pre-outfitting of ship sections. Background Technology

[0002] In the shipbuilding process, pre-outfitting is a key step in shortening the slipway cycle and improving construction efficiency.

[0003] Existing technology (patent document CN217805186U) discloses a fixture for installing outfitting components of a reverse-structured ship section and a ship, including a support frame, multiple support members, and an insertion channel. The length and number of each support member are selected according to the structure of the outfitting component. The tops of the multiple support members form a support surface for supporting the outfitting component. The insertion channel is used to connect with a lifting mechanism, which transports the support frame to a predetermined position and lifts it to raise the outfitting component to a predetermined height. This fixture for installing outfitting components of a reverse-structured ship section determines the installation angle of the outfitting component by precisely controlling the positioning points of the connection between the support members and the outfitting component. It accurately completes the installation of the outfitting component without damaging the paint on the surface, improving the installation efficiency, safety factor, and ship construction efficiency. It is simple and convenient to manufacture, operate, and install, making it suitable for widespread use.

[0004] Based on the above search and combined with existing technology, it was found that the existing tooling structures mostly adopt scattered non-standard tooling. Special tooling needs to be made separately for different sections and different outfitting processes. Not only is the tooling preparation cycle long and the material consumption high, resulting in an unnecessary increase in construction costs, but the different toolings also have poor versatility and most of them can only be treated as waste after use, resulting in a large amount of resource waste. Summary of the Invention

[0005] The core of this invention lies in the use of a sealed base, fixed support sleeve, sliding support rod, support plate, and fixing mechanism to solve the problem in existing technologies where separate special tooling is required for different sections and outfitting processes, resulting in increased manufacturing costs and wasted resources. Simultaneously, it can automatically complete the fitting and support of pre-outfitted workpieces, ensuring reliable support after locking.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A modular tooling for pre-outfitting of ship sections includes a sealed base with an internal cavity and a U-shaped component fixed to the bottom of the sealed base. The cavity of the sealed base is filled with a flowing medium, which is compressed under pressure. An input and output pipe with a valve body is also fixed and connected to one side of the sealed base. A fixed support sleeve is fixed to the top of the sealed base and communicates with the cavity inside the sealed base. A volumetric cavity for containing the flowing medium is formed inside the fixed support sleeve. A sliding support rod is slidably connected inside the fixed support sleeve. A piston with a sealing ring is fixed at the lower end of the sliding support rod. The side wall of the piston slides and seals against the inner wall of the volume chamber. A support plate is fixed to the upper end of the piston, and a fixing mechanism is installed on the upper end of the fixed support sleeve. The fixing mechanism is used to fix the sliding support rod.

[0008] By using a sealed base, fixed support sleeves, sliding support rods, support plates, and fixing mechanisms in combination, users can directly place the pre-outfitted workpiece on multiple support plates. Under the pressure of the pre-outfitted workpiece, multiple sliding support rods are compressed and descend, compressing the flowing medium in the volumetric cavity and the cavity of the sealed base. The flowing medium is compressed and automatically balances the pressure in multiple volumetric cavities, making the pressure on each sliding support rod equal. This allows multiple support plates to adapt to the bottom contour of the pre-outfitted workpiece, automatically completing the fitting support of the pre-outfitted workpiece without the need to customize the support structure according to the shape of the workpiece. At the same time, the number and installation position of the fixed support sleeves can be adjusted according to the size of the pre-outfitted workpiece and the support point requirements, realizing modular adjustment and reuse of the tooling, reducing material waste and preparation cycle. After the adaptive adjustment of the support height is completed, the position of the sliding support rods is locked by the fixing mechanism to maintain a stable support state and meet the support requirements of pre-outfitting operations.

[0009] Furthermore, the top of the sealed base is provided with multiple evenly distributed first through holes. The lower end of the fixed support sleeve is detachably fixed to the top of the sealed base and communicates with the first through holes. Several fixed support sleeves are provided and correspond one-to-one with several first through holes according to the usage requirements. The top of the sealed base can also be detachably fixed with multiple sealing components for sealing the first through hole.

[0010] Furthermore, the top of the sealed base is provided with multiple mounting slots, each of which corresponds to one of the multiple first through holes; The lower end of the fixed support sleeve is integrally formed with a fixing plate that is fixed to the top of the sealed base. The lower end of the fixing plate is integrally formed with a protruding ring that is inserted into the mounting groove. The inner side of the protruding ring is provided with a communication port that connects the first through hole and the bulk cavity. Sealing elements are fixed to the bottom and the periphery of the protruding ring.

[0011] Furthermore, a connecting plate is fixed to the top of the piston, and several connecting holes are opened on the connecting plate. Several evenly distributed fixing holes are opened on the support plate, and several fixing holes correspond one-to-one with several connecting holes.

[0012] Furthermore, the fixing mechanism includes a fixing plate, an adjusting screw, and a limiting tooth block. The fixing plate is fixed to the top of the fixing support sleeve. The adjusting screw is screwed through the fixing plate. The limiting tooth block is rotatably connected to the end of the adjusting screw near the sliding support rod. The lower end of the limiting tooth block slides against the top of the fixing support sleeve. The side of the limiting tooth block away from the adjusting screw is the tooth part. The sliding support rod has a toothed groove on its side wall that meshes with the teeth of the limiting tooth block.

[0013] Furthermore, the sliding support rod is a rod with a rectangular cross-section, and toothed grooves are provided on all four sides of the sliding support rod. The fixing mechanism is provided in four sets, each corresponding to one of the four sides of the sliding support rod.

[0014] Furthermore, the limit teeth of the four sets of fixing mechanisms have the same height, the tooth height of the grooves on opposite sides of the sliding support rod is the same, and the grooves on adjacent sides of the sliding support rod are staggered.

[0015] Furthermore, the lower end of the sealing component is integrally formed with a plug body that can be inserted into the first through hole and the mounting groove, and a sealing component is also fixed on the plug body.

[0016] Optionally, a reinforcing frame is fixedly embedded in the sealed base. The top and bottom of the reinforcing frame are fixed to the inner top wall and inner bottom wall of the sealed base, respectively. A second through hole is provided on the reinforcing frame. The reinforcing frame divides the cavity inside the sealed base into multiple small chambers. The second through hole is used to connect the multiple small chambers. The multiple first through holes correspond one-to-one with the multiple small chambers.

[0017] Compared with the prior art, the advantages of this invention are: 1. This solution utilizes a sealed base, fixed support sleeves, sliding support rods, support plates, and a fixing mechanism. When using the solution, the user first determines the location of the fixed support sleeve based on the size of the pre-outfitted workpiece and the required support points. Then, the fixed support sleeve is fixed, ensuring its cavity is connected to the cavity within the sealed base. Subsequently, the pre-outfitted workpiece is placed on multiple support plates. The workpiece's own weight will press down on the sliding support rods, which in turn drive the pistons to press down the flowing medium within the cavity. When the flowing medium is pressurized, it flows through the cavity of the sealed base, automatically balancing the pressure in each volume chamber, making the reaction force on each sliding support equal. This allows multiple support plates to automatically adapt to the bottom contour of the pre-outfitted workpiece, fitting snugly against the bottom of the workpiece without the need to customize the support structure according to the shape of the workpiece. At the same time, the number and position of the fixed support sleeves can be adjusted according to the size of the pre-outfitted workpiece and the support point requirements, realizing modular adjustment and reuse of the tooling, reducing material waste and preparation cycle of the tooling.

[0018] 2. This solution sets the height of the limiting teeth of the four sets of fixing mechanisms to be the same, and sets the height of the teeth of the grooves on opposite sides of the sliding support rod to be the same. The teeth of the grooves on adjacent sides of the sliding support rod are staggered. In this way, when locking, at least two sets of limiting teeth of the fixing mechanisms can be stably engaged with the grooves of the sliding support rod, which improves the stability of the locking state and reduces the possibility of the sliding support rod sliding under force.

[0021] The technical solutions will now be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention.

[0022] First implementation method: Please see Figures 1-2 , Figures 4-8 A modular tooling for pre-outfitting of ship sections includes a sealed base 1 with an internal cavity and a U-shaped piece 2 fixed to the bottom of the sealed base 1. The cavity of the sealed base 1 is filled with a flowing medium, which is compressed under pressure. The sealed base 1 is also fixed and connected to an input / output pipe 14 with a valve body (e.g., a manual valve or a solenoid valve) on one side. A fixed support sleeve 3 is fixed on the top of the sealed base 1 and communicates with the inner cavity of the sealed base 1. A volumetric cavity 32 for containing the flowing medium is formed inside the fixed support sleeve 3. A sliding support rod 4 is slidably connected inside the fixed support sleeve 3. A piston 41 with a sealing ring 411 is fixed at the lower end of the sliding support rod 4. The peripheral side wall of the piston 41 is in sealing sliding contact with the inner wall of the volume cavity 32. A support plate 5 is fixed to the upper end of the piston 41, and a fixing mechanism 6 is installed on the upper end of the fixed support sleeve 3. The fixing mechanism 6 is used to fix the sliding support rod 4.

[0023] Based on the above structure, when using the device, the user first determines the location where the fixed support sleeve 3 needs to be installed according to the size of the pre-outfitted workpiece and the required support points. Then, the fixed support sleeve 3 is fixed, ensuring that the cavity 32 of the fixed support sleeve 3 is connected to the cavity inside the sealed base 1. Subsequently, the pre-outfitted workpiece is placed on multiple support plates 5. The weight of the pre-outfitted workpiece will press down on multiple sliding support rods 4. The sliding support rods 4 drive the piston 41 to press down the flowing medium in the cavity 32. After being pressurized, the flowing medium will flow through the cavity of the sealed base 1, automatically balancing the pressure in each cavity 32, making the reaction force on each sliding support rod 4 equal, thereby allowing the multiple support plates 5 to automatically adapt to the pre-outfitted workpiece. The bottom contour fits snugly against the bottom of the workpiece, eliminating the need for custom-designed support structures based on the workpiece shape. After adaptive adjustment, the position of the sliding support rod 4 is locked by the fixing mechanism 6 to maintain the support state, allowing subsequent pre-outfitting operations to proceed (the specific operation method is the same as existing technology and will not be elaborated here). After the operation is completed, the fixing mechanism 6 is released, the flowing medium automatically depressurizes and pushes the piston 41 and the sliding support rod 4 to reset, allowing the tooling to be reused for supporting the next pre-outfitting workpiece. At the same time, the number and position of the fixed support sleeve 3 can be adjusted according to the size of the pre-outfitting workpiece and the support point requirements, realizing modular adjustment and reuse of the tooling, reducing material waste and preparation cycle.

[0024] It should be noted that the flowing medium in this application includes gases (such as air, nitrogen, carbon dioxide, etc.), which are significantly compressible and whose density changes significantly with pressure and temperature. This allows them to automatically balance pressure during use and provide a certain buffering effect when under pressure. In addition, the input and output pipes 14 can be connected to an external air supply device (such as an air pump) through a quick-connect structure (such as a quick connector for air) to fill or replenish the flowing medium into the cavity of the sealed base 1. When the input and output pipes 14 are not connected to an external air supply device, they can also be used directly to discharge the flowing medium and relieve pressure. Of course, the aforementioned devices or apparatuses are all prior art, and their specific structures, working principles, and connection methods are all prior art. Specific models can be selected by the staff according to actual usage needs, and will not be described in detail here.

[0025] Furthermore, the top of the sealed base 1 is provided with a plurality of evenly distributed first through holes 11. The lower end of the fixed support sleeve 3 is detachably fixed to the top of the sealed base 1 and communicates with the first through holes 11. The fixed support sleeve 3 is provided with a plurality of holes and corresponds one-to-one with a plurality of first through holes 11 according to the usage requirements. The top of the sealed base 1 can also be detachably fixed with multiple sealing components 7 for sealing the first through hole 11; by setting the sealing components 7, the unused first through hole 11 can be sealed and plugged, ensuring the sealing performance of the internal cavity of the sealed base 1, thereby maintaining the pressure balance effect of the flowing medium.

[0026] Furthermore, the top of the sealed base 1 is provided with multiple mounting grooves 12, each corresponding to a number of first through holes 11. The lower end of the fixed support sleeve 3 is integrally formed with a fixing plate 31 fixed to the top of the sealed base 1. The lower end of the fixing plate 31 is integrally formed with a protruding ring 311 inserted into the mounting groove 12. The inner side of the protruding ring 311 is provided with a communication port 33 connecting the first through hole 11 and the volumetric cavity 32. Sealing elements 8 (such as sealing rings, sealing gaskets, etc.) are fixed to the bottom and periphery of the protruding ring 311. The positioning method of the protruding ring 311 being embedded in the mounting groove can improve the convenience of the fixed support sleeve 3 installation and positioning. At the same time, the sealing element 8 can seal the connection position, further improving the sealing performance and reducing the probability of leakage of the flowing medium.

[0027] Furthermore, the fixing mechanism 6 includes a fixing plate 61, an adjusting screw 62, and a limiting tooth block 63. The fixing plate 61 is fixed to the top of the fixing support sleeve 3. The adjusting screw 62 is screwed through the fixing plate 61. The limiting tooth block 63 is rotatably connected to the end of the adjusting screw 62 near the sliding support rod 4. The lower end of the limiting tooth block 63 slides against the top of the fixing support sleeve 3. The side of the limiting tooth block 63 away from the adjusting screw 62 is a toothed part. The side wall of the sliding support rod 4 is provided with a toothed groove 42 that meshes with the toothed part of the limiting tooth block 63. When it is necessary to lock the sliding support rod 4, rotate the adjusting screw 62 to push the limiting tooth block 63 to move towards the sliding support rod 4, so that the teeth of the tooth block 63 mesh with the tooth groove 42 of the sliding support rod 4, which can restrict the sliding of the sliding support rod 4. The operation is simple and convenient, and the locking is stable and reliable.

[0028] Furthermore, in order to improve the fixing strength of the sliding support rod 4, the sliding support rod 4 is a rod with a rectangular cross section, and toothed grooves 42 are provided on all four sides of the sliding support rod 4. The fixing mechanism 6 is provided with four sets, which correspond one-to-one with the four sides of the sliding support rod 4. To facilitate better fixation of the sliding support rod 4, the height of the teeth of the limiting blocks 63 of the four sets of fixing mechanisms 6 can be set to be the same. At the same time, the height of the teeth of the grooves 42 on opposite sides of the sliding support rod 4 can be set to be the same, and the teeth of the grooves 42 on adjacent sides of the sliding support rod 4 can be staggered. In this way, when locking, at least two sets of limiting blocks 63 of fixing mechanisms 6 can be stably engaged with the grooves 42 of the sliding support rod 4, which improves the stability of the locking state and reduces the possibility of the sliding support rod 4 sliding under force.

[0029] Furthermore, the lower end of the plugging component 7 is integrally formed with a plug body 71 that is inserted into the first through hole 11 and the mounting groove 12. A sealing component 8 is also fixed on the plug body 71 to ensure the sealing performance after plugging, further reduce the possibility of leakage of the flowing medium from the idle first through hole 11, and improve the reliability of the entire device.

[0030] Second implementation method: Please see Figures 1-3 A modular tooling for pre-outfitting ship sections, which differs from the first embodiment in that: A reinforcing frame 13 is fixedly embedded in the sealed base 1. The top and bottom of the reinforcing frame 13 are fixed to the inner top wall and inner bottom wall of the sealed base 1, respectively. A second through hole 131 is provided on the reinforcing frame 13. The reinforcing frame 13 divides the cavity inside the sealed base 1 into multiple small chambers. The second through hole 131 is used to connect the multiple small chambers. Multiple first through holes 11 correspond one-to-one with the multiple small chambers. The reinforcing frame 13 can improve the overall structural strength of the sealed base 1, reduce the probability of the sealed base 1 being deformed under pressure, and at the same time, it does not affect the flow of the fluid medium in the cavity, thus ensuring the pressure balance effect.

[0031] The above description is merely a preferred embodiment of the present invention; it encompasses all the protection scope of the present invention. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in the present invention, based on the technical solutions and improved concepts of the present invention, should be covered within the protection scope of the present invention.
