Description

Technical Field

[0001] This utility model belongs to the field of positioning device technology, specifically relating to a positioning device for the construction of ship outfitting modules. Background Technology

[0002] The positioning device for ship outfitting module construction is a specialized device used in the shipbuilding process to precisely position and securely fix various outfitting modules. The modules need to be precisely installed inside or outside the hull to ensure the ship's functionality, safety, and comfort.

[0003] Application No. 202411433956.0 discloses a positioning device for the construction of ship outfitting modules. "When the positioning device for the construction of ship outfitting modules is used, the user places the workpiece to be welded against the inner wall of the fixed plate in the flipping component, rotates the lead screw, and the rotation of the lead screw drives the sliding plate forward through the thread on the outer wall. The sliding plate moves forward to adjust the processing dimensions of the workpiece. Then, the rotating rod in the clamping component is rotated, and the rotating rod drives the gear to rotate. The rotation of the gear drives the sliding rod to move left and right through the teeth on the inner side of the sliding rod. The sliding rod drives the connecting plate to move left and right, and the left and right movement of the connecting plate, in conjunction with the fixed plate and the sliding plate, clamps and fixes the workpiece." In the above design, a connecting plate that moves left and right is used to clamp the workpiece. However, when the contact surface of the workpiece is inclined or has an irregular shape, the connecting plate is difficult to precisely adapt to the inclined surface of the workpiece and cannot adaptively adjust according to the specific shape and angle of the workpiece. This will cause the clamping force to concentrate in certain local areas, which can easily lead to poor contact or local stress concentration during the clamping process. Such problems not only reduce the reliability of clamping, but also are very likely to damage the surface of the workpiece, leading to unstable clamping, workpiece displacement or deformation and other adverse consequences, which seriously affect the accuracy and quality of machining, making it necessary to use special fixtures for different workpieces. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning device for the construction of ship outfitting modules, so as to solve the problem mentioned in the background art that the left and right moving connecting plates are difficult to adapt to tilt or irregular surfaces, resulting in uneven clamping force, poor contact, unstable clamping, workpiece damage and reduced processing accuracy, which makes it necessary to use special fixtures for different workpieces.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for constructing ship outfitting modules, comprising: an operating platform, an installation plate on the end face of the operating platform, a steering component connected between the operating platform and the installation plate, a support plate on the end face of the installation plate, a bearing plate on the end face of the support plate, and support columns connected between the installation plate and the support plate, as well as between the support plate and the bearing plate. Several pressing components are provided on the end faces of the installation plate and the bearing plate adjacent to the support plate, and each pressing component is evenly distributed on the end faces of the installation plate and the bearing plate.

[0006] Preferably, the pressing assembly includes an electric push rod, a first motor, a second motor, and a pressure plate. The electric push rod is fixedly connected to the end face of the mounting plate and the bearing plate adjacent to the support plate. A connecting plate is installed at the output end of the electric push rod. The first motor is vertically arranged on the end face of the connecting plate. A first rotating shaft is connected to the output end of the first motor. A horizontal plate is installed at the end of the first rotating shaft away from the first motor. Vertical plates are installed on both sides of the outer wall of the horizontal plate. The second motor is horizontally installed on the side wall of the vertical plate. A second rotating shaft is connected to the output end of the second motor. A fixing plate is installed on the outer wall of the second rotating shaft. The pressure plate is connected to the outer wall of the fixing plate.

[0007] The outer wall of the pressure plate is provided with several grooves, and each groove is evenly distributed on the end face of the pressure plate adjacent to the support plate. The grooves increase the friction between the pressure plate and the ship outfitting module, thereby improving stability.

[0008] The support plate has a receiving groove that is adapted to the pressure plate. The size of the receiving groove is larger than that of the pressure plate. This key design provides ample space for the flexible movement of the pressure plate, ensuring that it can move smoothly up and down and make precise tilt adjustments during operation.

[0009] Through the above technical solution:

[0010] In use, the ship outfitting module must first be placed stably on the upper surface of the support plate. Then, activate each electric actuator, which acts as a power source and drives the subsequent components to move.

[0011] After the electric push rod is activated, it drives the first motor, the second motor, and the pressure plate connected to them, slowly approaching the ship's outfitting module. During this approach, pressure sensors on the pressure plate monitor the contact pressure between the pressure plate and the module in real time. Based on the feedback from the pressure sensors, the pressure plate can automatically make initial adaptive adjustments to suit the external shape and size of the ship's outfitting module. This adjustment ensures that the pressure plate can initially position itself with appropriate force and angle upon contacting the module surface, avoiding damage or inaccurate positioning caused by improper contact. The pressure sensor data is transmitted to the control system in real time, which adjusts the stroke and speed of the electric push rod accordingly to ensure good initial contact between the pressure plate and the module surface. Through this adaptive adjustment mechanism, the pressure plate can automatically adapt to the external contour of the module in the initial contact with the module surface, laying the foundation for subsequent precise positioning and fixing.

[0012] Once the pressure plate makes initial contact with the module surface, the system activates the corresponding first and second motors based on the specific external shape and slope angle of the ship outfitting module. The first motor drives the horizontal plate to rotate along the axis of the first shaft via a first rotating shaft. This rotation drives the second motor and the vertical plate to rotate in the horizontal plane, achieving precise horizontal adjustment of the pressure plate. The second motor drives the pressure plate to rotate in the vertical plane via a second rotating shaft and a fixed plate, adjusting the tilt angle of the pressure plate to precisely fit the slope surface of the ship outfitting module.

[0013] Through the aforementioned adjustments, the pressure plates can precisely conform to the surface contours of the ship outfitting module, ensuring that each pressure plate makes uniform contact with the module surface at multiple points. This uniform contact not only improves the accuracy and stability of positioning but also ensures that the module will not shift or loosen during subsequent processing. The first and second motors work together to achieve precise adjustment of the pressure plates in the horizontal and vertical directions, enabling them to accurately adapt to the sloping surfaces of the ship outfitting module and greatly enhancing the adaptability of the device to outfitting modules of different shapes and sizes. Whether it is a planar module or a module with a complex sloping surface, the pressure plates can achieve a perfect fit through precise adjustment, reducing the need for special fixtures for different modules.

[0014] The various pressure plates and support plates work together to stably clamp the ship outfitting modules vertically. Through the coordinated operation of multiple pressing components, the modules are secured omnidirectionally, ensuring they will not shift or loosen during subsequent processing. This positioning device features selective pressing, allowing for flexible adjustment of the pressing components' working state according to specific needs. Before welding, the system automatically retracts the pressing components corresponding to the welding area. Specifically, when the welding end face is detected, the control system issues a command to temporarily remove the pressure plates and related pressing components in that area, ensuring an unobstructed welding area. This design prevents damage or interference to the pressure plates from high-temperature molten metal or electric arcs during welding, protecting the equipment and extending its service life. The removal of the pressure plates not only protects the equipment but also provides a wider operating space for welding. Welders can perform welding operations more conveniently, ensuring the integrity and quality of the weld. Simultaneously, it avoids welding dead angles caused by pressing components obstructing the weld, making the welding process more efficient and precise. After welding is completed, the control system automatically activates the previously retracted pressing components, resetting the pressure plates and re-secureing the module. This automatic reset function ensures that the welding area is firmly clamped immediately after welding, maintaining the shape and dimensional accuracy of the welded area and preventing displacement caused by welding deformation or stress release. After re-fixation, the pressure plate tightly adheres to the surface of the welded module, ensuring the processing accuracy and stability of the welded area. This not only avoids welding deformation but also provides a precise benchmark for subsequent processing operations, improving the overall processing quality and consistency. Because the pressing component can be flexibly adjusted and automatically retracted, there are no welding dead corners caused by the pressing component obstructing the welding process, allowing the welding operation to fully cover all areas to be welded, ensuring the integrity and strength of the weld, and improving the quality and reliability of the welding.

[0015] In summary, the optimized operating procedures make the positioning and securing of ship outfitting modules more efficient, precise, and flexible. This positioning device not only adapts to modules of different shapes and sizes but also provides reliable securing during welding, ensuring processing quality and safety.

[0016] The steering assembly includes a third motor and ball bearings. The third motor is mounted on the outer wall of the operating table. The output end of the third motor is connected to a third rotating shaft. The end of the third rotating shaft away from the third motor is connected to a mounting plate. The ball bearings are installed between the operating table and the mounting plate. A ball bearing storage groove is provided on the support plate to prevent the ball bearings from rolling off.

[0017] Preferably, a welding robot is provided on the operating table, and the output end of the welding robot is located on one side of the end face of the support plate.

[0018] Specifically, the third motor is activated. This motor, serving as the core power source for the orientation assembly, transmits power through the third rotating shaft, driving the mounting plate to rotate. Since the mounting plate and support plate are tightly connected via support columns and ball bearings, the ship outfitting module placed on the support plate rotates synchronously with the mounting plate. This design achieves integrated rotation of the mounting plate and the ship outfitting module, effectively adjusting the relative position between the ship outfitting module and the welding robot. Operators can flexibly adjust the direction and angle of the ship outfitting module to meet different welding requirements, ensuring the welding area is precisely aligned with the welding robot's operating range. This design not only optimizes the welding operating space and improves welding accuracy and quality but also enhances the adaptability and flexibility of the device. Automated orientation reduces human intervention, improves overall processing efficiency and consistency, and provides strong technical support for high-quality welding of the ship outfitting module.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] (1) This utility model, by setting up components such as an electric push rod, a first motor, a second motor, and a pressure plate, can adapt to ship outfitting modules of different shapes. In actual use, after the electric push rod is started, it drives the pressure plate to initially approach the ship outfitting module. Subsequently, the first motor is responsible for accurately adjusting the pressure plate in the horizontal direction, while the second motor is used to adjust the tilt angle of the pressure plate, so that the pressure plate can accurately fit the sloping surface of the ship outfitting module. This design greatly reduces the need for special fixtures for different modules.

[0021] (2) This utility model effectively avoids the problem of welding dead angles by setting up multiple pressing components symmetrically distributed vertically. In practical applications, each pressing component can be selectively activated as needed to ensure that the welding area is unobstructed. This design can prevent the high-temperature molten metal or electric arc from damaging or interfering with the pressure plate during the welding process, while eliminating welding dead angles caused by the pressing components, making the welding process more efficient and precise.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-3 As shown, this utility model provides the following technical solution: a positioning device for the construction of ship outfitting modules, comprising: an operating table 1, an installation plate 2 on the end face of the operating table 1, a steering component connected between the operating table 1 and the installation plate 2, a support plate 3 on the end face of the installation plate 2, a bearing plate 4 on the end face of the support plate 3, and support columns 5 connected between the installation plate 2 and the support plate 3 and between the support plate 3 and the bearing plate 4, and a plurality of pressing components provided on the end faces of the installation plate 2 and the bearing plate 4 adjacent to the support plate 3, and the pressing components are evenly distributed on the end faces of the installation plate 2 and the bearing plate 4.

[0029] Furthermore, the pressing assembly includes an electric push rod 6, a first motor 8, a second motor 12, and a pressure plate 15. The electric push rod 6 is fixedly connected to the mounting plate 2 and the end face of the bearing plate 4 adjacent to the support plate 3. A connecting plate 7 is installed at the output end of the electric push rod 6. The first motor 8 is vertically arranged on the end face of the connecting plate 7. A first rotating shaft 9 is connected to the output end of the first motor 8. A horizontal plate 10 is installed at the end of the first rotating shaft 9 away from the first motor 8. Vertical plates 11 are installed on both sides of the outer wall of the horizontal plate 10. The second motor 12 is horizontally installed on the side wall of the vertical plate 11. A second rotating shaft 13 is connected to the output end of the second motor 12. A fixing plate 14 is installed on the outer wall of the second rotating shaft 13. The pressure plate 15 is connected to the outer wall of the fixing plate 14.

[0030] The outer wall of the pressure plate 15 is provided with a number of grooves 16. Each groove 16 is evenly distributed on the end face of the pressure plate 15 adjacent to the support plate 3. The grooves 16 increase the friction between the pressure plate 15 and the ship outfitting module, thereby improving stability.

[0031] The support plate 3 has a receiving groove 17, which is adapted to the pressure plate 15. The size of the receiving groove 17 is larger than that of the pressure plate 15. This key design provides sufficient space for the flexible movement of the pressure plate 15, ensuring that it can move smoothly up and down and make precise tilt adjustments during operation.

[0032] Through the above technical solution:

[0033] In use, the ship outfitting module must first be placed stably on the upper surface of the support plate 3. Then, each electric push rod 6 is activated, and the electric push rod 6, acting as a power source, begins to work, driving the subsequent components to move.

[0034] After the electric push rod 6 is activated, it drives the first motor 8, the second motor 12, and the pressure plate 15 connected to it to slowly approach the ship outfitting module. During the approach, the pressure sensor installed on the pressure plate 15 monitors the contact pressure between the pressure plate 15 and the module in real time. Based on the feedback from the pressure sensor, the pressure plate 15 can automatically make preliminary adaptive adjustments to the external shape and size of the ship outfitting module. This adjustment ensures that the pressure plate 15 can be initially positioned with appropriate force and angle when contacting the module surface, avoiding damage or inaccurate positioning caused by improper contact. The data from the pressure sensor is transmitted to the control system in real time, and the control system adjusts the stroke and speed of the electric push rod 6 accordingly to ensure good initial contact between the pressure plate 15 and the module surface. Through this adaptive adjustment mechanism, the pressure plate 15 can automatically adapt to the external contour of the module in the initial contact with the module surface, laying the foundation for subsequent precise positioning and fixing.

[0035] Once the pressure plate 15 makes initial contact with the module surface, the system will activate the corresponding first motor 8 and second motor 12 according to the specific external shape and slope angle of the ship outfitting module. The first motor 8 drives the horizontal plate 10 to rotate along the axis of the first rotating shaft 9 through the first rotating shaft 9. This rotation drives the second motor 12 and the vertical plate 11 to rotate in the horizontal plane, achieving precise horizontal adjustment of the pressure plate 15. The second motor 12 drives the pressure plate 15 to rotate in the vertical plane through the second rotating shaft 13 and the fixed plate 14, adjusting the tilt angle of the pressure plate 15 to precisely fit the slope surface of the ship outfitting module.

[0036] After the above adjustments, the pressure plates 15 can precisely conform to the surface contour of the ship outfitting module, ensuring that each pressure plate 15 makes uniform contact with the module surface at multiple points. This uniform contact at multiple points not only improves the positioning accuracy and stability but also ensures that the module will not shift or loosen during subsequent processing. The first motor 8 and the second motor 12 work together to achieve precise adjustment of the pressure plates 15 in the horizontal and vertical directions, enabling them to accurately adapt to the sloping surface of the ship outfitting module, greatly enhancing the adaptability of the device to outfitting modules of different shapes and sizes. Whether it is a planar module or a module with a complex sloping surface, the pressure plates 15 can achieve a perfect fit through precise adjustment, reducing the need for special fixtures for different modules.

[0037] Each pressure plate 15 works in conjunction with the support plate 3 to stably clamp the ship outfitting module vertically. Through the coordinated operation of multiple pressing components, the module is secured in all directions, ensuring it will not shift or loosen during subsequent processing. This positioning device features selective pressing, allowing for flexible adjustment of the pressing components' working state according to specific needs. Before welding, the system automatically retracts the pressing components corresponding to the welding area. Specifically, when the welding end face is detected, the control system issues a command to temporarily remove the pressure plates 15 and related pressing components in that area, ensuring the welding area is unobstructed. This design prevents damage or interference to the pressure plates 15 caused by high-temperature molten metal or electric arcs during welding, protecting the equipment and extending its service life. The removal of the pressure plates 15 not only protects the equipment but also provides a wider operating space for welding. Welders can perform welding operations more conveniently, ensuring the integrity and quality of the weld. Simultaneously, it avoids welding dead angles caused by obstruction from the pressing components, making the welding process more efficient and precise. After welding is completed, the control system automatically activates the previously retracted pressing component, resetting the pressure plate 15 and re-fixing the module. This automatic reset function ensures that the welding area is firmly clamped immediately after welding, maintaining the shape and dimensional accuracy of the welding area and preventing displacement caused by welding deformation or stress release. After re-fixing, the pressure plate 15 fits tightly against the surface of the welded module, ensuring the processing accuracy and stability of the welding area. This not only avoids welding deformation but also provides a precise reference for subsequent processing operations, improving the overall processing quality and consistency. Because the pressing component can be flexibly adjusted and automatically retracted, there are no welding dead corners caused by the pressing component obstructing the welding process, allowing the welding operation to fully cover all areas to be welded, ensuring the integrity and strength of the weld, and improving the quality and reliability of the welding.

[0038] To more effectively prevent deformation of the ship outfitting module during clamping, auxiliary blocks can be strategically placed inside the module. These auxiliary blocks must be precisely positioned within the module, their location calculated to ensure even distribution of the clamping force from the pressure plate 15. They are typically made of high-strength materials, such as steel or aluminum alloy, to provide sufficient support strength and good durability. Their shape and size are designed based on the module's specific structure and stress conditions to effectively support critical components and prevent stress concentration or localized deformation during clamping. When the pressure plate 15 applies clamping force to the ship outfitting module, the auxiliary blocks absorb and distribute this force. Specifically, the force from the pressure plate 15 is first transferred to the auxiliary blocks, and then evenly distributed to various parts of the module with the aid of the auxiliary blocks. This design ensures uniform force distribution, preventing module deformation or damage due to excessive localized stress.

[0039] In summary, the optimized operating procedures make the positioning and securing of ship outfitting modules more efficient, precise, and flexible. This positioning device not only adapts to modules of different shapes and sizes but also provides reliable securing during welding, ensuring processing quality and safety.

[0040] Please see Figure 1 and Figure 4 As shown, the steering assembly includes a third motor 18 and a ball bearing 20. The third motor 18 is mounted on the outer wall of the operating table 1. The output end of the third motor 18 is connected to a third rotating shaft 19. The end of the third rotating shaft 19 away from the third motor 18 is connected to the mounting plate 2. The ball bearing 20 is installed between the operating table 1 and the mounting plate 2. The support plate 3 has a storage slot for the ball bearing 20 to prevent the ball bearing 20 from rolling off.

[0041] Furthermore, a welding robot 21 is installed on the operating table 1, and the output end of the welding robot 21 is located on one side of the end face of the support plate 3.

[0042] Specifically, the third motor 18 is activated. This motor, as the core power source of the orientation assembly, transmits power through the third rotating shaft 19, driving the mounting plate 2 to rotate. Since the mounting plate 2 and the support plate 3 are tightly connected by support columns 5 and ball bearings 20, the ship outfitting module placed on the support plate 3 rotates synchronously with the rotation of the mounting plate 2. This design achieves an integrated rotation effect between the mounting plate 2 and the ship outfitting module, thereby effectively adjusting the relative position between the ship outfitting module and the welding robot 21. Operators can flexibly adjust the direction and angle of the ship outfitting module to meet different welding requirements, ensuring that the welding area is precisely aligned with the operating range of the welding robot 21. This design not only optimizes the welding operating space and improves welding accuracy and quality, but also enhances the adaptability and flexibility of the device. Automated orientation reduces human intervention, improves overall processing efficiency and consistency, and provides strong technical support for high-quality welding of the ship outfitting module.
