Description

Technical Field

[0001] This utility model belongs to the field of welding fixture technology, and in particular relates to a welding fixture for communication buoys. Background Technology

[0002] A communication buoy is essentially a floating platform whose core function is to establish a communication link between various devices (such as underwater sensors, drones, and ships) and a remote control center in the vast ocean, lakes, or other bodies of water. It's like a "mobile communication base station" or "Wi-Fi hotspot" built at sea.

[0003] There is a communication buoy 7, such as Figure 6 As shown, the communication buoy 7 includes a ring-shaped buoy base plate 7-1, on which four mounting plates 7-3 are fixedly connected, evenly distributed along its circumference. Each mounting plate 7-3 has at least two through holes 7-7. A mounting ring pipe 7-2 is installed between the four mounting plates 7-3. The buoy also includes an arc-shaped connecting pipe 7-5 positioned between two opposing mounting plates 7-3, with two corresponding mounting plates 7-7 fixedly connected to each end of the arc-shaped connecting pipe 7-5. -3 The connecting pipe base plate 7-6 is fixedly connected to the mounting plate 7-3. Each connecting pipe base plate 7-6 has several base plate through holes 7-8 corresponding to several vertical plate through holes 7-7 opened on the corresponding mounting plate 7-3. It also includes a connecting pipe support rod 7-4 passing through the arc-shaped connecting pipe 7-5. The lower end of the connecting pipe support rod 7-4 is fixedly connected to the corresponding mounting plate 7-3. The lower end of the connecting pipe support rod 7-4 has several strip-shaped through holes corresponding to several vertical plate through holes 7-7 opened on the corresponding mounting plate 7-3.

[0004] Before welding the aforementioned communication buoys, it is necessary to position each component of the communication buoy separately. Existing technology generally involves placing each component of the communication buoy directly on a workbench without specific positioning measures. This can easily lead to large welding errors during the welding process, resulting in inaccurate welding and a low yield rate of communication buoys. Therefore, it is urgent to design a welding fixture specifically for communication buoys to solve the above problems and achieve precise welding operations for communication buoys. Utility Model Content

[0005] This invention provides a reasonably designed welding fixture for communication buoys to address technical problems existing in prior art. This invention enables precise positioning and clamping of each component of the communication buoy, ensuring stable component positions during welding, avoiding displacement and angular deviation, thereby improving welding accuracy and product quality.

[0006] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is as follows: A communication buoy welding fixture includes a mounting bracket, on which two opposingly arranged vertical plate positioning components one and two opposingly arranged vertical plate positioning components two are movably connected for positioning and installing four sets of mounting vertical plates; a centering drive component is installed on the mounting bracket for centering and clamping the buoy seat plate; it also includes a vertical pipe clamping component for clamping the arc-shaped connecting pipe and a height adjustment component for adjusting the longitudinal position of the vertical pipe clamping component; the centering drive component includes a drive seat structure installed on the mounting bracket, on which two opposingly arranged movable seats one and two opposingly arranged movable seats two are movably connected, and a V-shaped groove is opened at the inner end of each movable seat one and each movable seat two, and each vertical plate positioning component is respectively installed on each movable seat; it also includes a screw drive mechanism installed on the drive seat structure for driving the two movable seats one or the two movable seats two to move synchronously in opposite directions.

[0007] The advantages and positive effects of this utility model are as follows: This utility model provides a welding fixture for communication buoys. A centering drive assembly installed on the mounting bracket is used to center and clamp the buoy base plate. The automatic centering function ensures the buoy base plate is centered, avoiding welding errors caused by center offset. Multiple sets of upright plate positioning assemblies are used to position and install four sets of mounting upright plates. These, along with several movable seats in the centering drive assembly, provide a movable installation platform for the upright plate positioning assemblies, enabling a movable connection between the multiple sets of upright plate positioning assemblies. This allows for flexible adjustment of the mounting plate positions, ensuring the stability of the four sets of mounting upright plates. During welding, accurate spatial distribution is maintained to prevent welding misalignment caused by inaccurate positioning. Simultaneously, the positioning assembly of the vertical plate moves synchronously with the moving base, achieving coordinated positioning of the installation vertical plate and the buoy base plate. The inclined structure of the V-shaped grooves at the inner ends of several moving bases naturally guides the buoy base plate towards the center during clamping, utilizing the centripetal force generated by the inclined surface to assist in automatic centering, thereby improving the initial positioning accuracy of clamping. The included vertical pipe clamping assembly and height adjustment assembly, which adjusts its longitudinal position, ensure that the arc-shaped connecting pipe can be reliably clamped and fixed at different heights, preventing shaking or displacement during welding. In summary, this utility model, by integrating the installation bracket, vertical plate positioning assembly, centering drive assembly, vertical pipe clamping assembly, and height adjustment assembly, constructs a complete communication buoy welding positioning system. This system achieves precise fixing and position adjustment of key buoy components, effectively reducing component offset during welding and improving welding accuracy and product consistency.

[0021] To further understand the invention content, features, and effects of this utility model, the following embodiments are provided in detail:

[0022] Please see Figure 1 The communication buoy welding fixture of this utility model includes a mounting bracket 1, on which two opposingly arranged vertical plate positioning components 3 and two opposingly arranged vertical plate positioning components 6 are movably connected for positioning and installing four sets of mounting vertical plates 7-3; a centering drive component 2 is installed on the mounting bracket 1 for centering and clamping the buoy seat plate 7-1; it also includes a vertical pipe clamping component 5 for clamping the arc-shaped connecting pipe 7-5 and a height adjustment component 4 for adjusting the longitudinal position of the vertical pipe clamping component 5; as shown Figure 3As shown, the centering drive assembly 2 includes a drive seat structure mounted on the mounting bracket 1. Two opposing movable seats 2-5 and two opposing movable seats 2-8 are movably connected to the drive seat structure. V-grooves are formed at the inner ends of each movable seat 2-5 and each movable seat 2-8. In practical applications, a V-groove refers to a groove structure with a specific geometric shape, which can be directly formed at the inner end of the movable seat by machining, or it can be achieved by welding or assembling additional components with V-grooves. The V-groove inclined surface structure generates a centripetal force during clamping, guiding the buoy seat plate 7-1 to automatically move towards the center, thereby improving the initial positioning accuracy. Each upright plate positioning assembly is mounted on its respective movable seat. The assembly also includes a screw drive mechanism mounted on the drive seat structure, used to drive the two movable seats 2-5 or the two movable seats 2-8 to move synchronously in opposite directions.

[0023] Through the above-described configuration, an integrated mounting bracket, upright positioning assembly, centering drive assembly, riser clamping assembly, and height adjustment assembly are constructed to create a complete communication buoy welding positioning system. This system enables precise fixing and position adjustment of key buoy components, effectively reducing component misalignment during welding and improving welding accuracy and product consistency. Compared with existing technologies, this invention solves the problems of large welding errors and low yield rates caused by the lack of positioning measures during communication buoy welding, providing reliable technical support for precise welding of communication buoys.

[0024] The structure of upright positioning component 3 is the same as that of upright positioning component 6; for example Figure 2 As shown, the upright plate positioning assembly 6 includes a T-shaped support 6-1 mounted on a corresponding movable seat, and an adjustable seat plate 6-5 with a longitudinally extending adjustment slot 6-4. Two limiting slide plates 6-2 with an L-shaped structure and opposite arrangement are mounted on the adjustable seat plate 6-5. The T-shaped support 6-1 slides through the groove formed by the two limiting slide plates 6-2. The T-shaped support 6-1 and the adjustable seat plate 6-5 are locked together by a locking knob passing through the adjustment slot 6-4. The assembly also includes an upright plate positioning plate 6-3 detachably connected to the adjustable seat plate 6-5. The upright plate positioning plate 6-3 has several through holes that correspond one-to-one with several upright plate through holes 7-7 opened on the mounting upright plate 7-3. The adjustable seat plate 6-5 has positioning mounting holes 6-6 for mounting the upright plate positioning plate 6-3 and distributed vertically.

[0025] Among them, the T-shaped support 6-1 refers to a support component with a T-shape, which can be integrally formed from metal or assembled by welding. In practical applications, the T-shaped support 6-1 is installed on the moving base as a basic support component, providing a rigid connection while ensuring that the positioning component moves synchronously with the moving base. The adjustable seat plate 6-5 refers to a plate-like structure with longitudinal adjustment function, which can be achieved by machining adjustment slots 6-4 on a metal plate. The purpose of the adjustment slots 6-4 is to guide the adjustable seat plate 6-5 to move precisely in the longitudinal direction and avoid lateral deviation. The limiting slide plate 6-2 can be understood as a guide component with an L-shaped cross-section, which can be formed by bending or welding. Its main function is to cooperate with the T-shaped support 6-1 to form a restraining groove to ensure stability during the adjustment process. The upright positioning plate 6-3 is a replaceable positioning component. The layout of the through holes on it can be customized according to the needs of different specifications of communication buoys, thereby achieving rapid adaptation.

[0026] Specifically, precise positioning of the mounting plate 7-3 is achieved through the organic cooperation between the various components. The T-shaped support 6-1, fixed to the movable base, provides a stable support foundation for the entire positioning assembly. The adjustable seat plate 6-5 slides into the T-shaped support 6-1 via the limiting slide plate 6-2. This structural design not only allows for flexible adjustment of the longitudinal position but also effectively prevents rotation or tilting during adjustment. The locking knob ensures reliable fixation after adjustment, maintaining positioning accuracy even under vibration during welding. The mounting plate 6-3 can be selectively installed at different heights via the positioning mounting holes 6-6. This layered design significantly expands the adjustment range, enabling the fixture to adapt to the installation requirements of buoys of different sizes. Through the above structural design, not only is the lack of longitudinal adjustment capability in the mounting plate assembly resolved, but the function of quickly replacing positioning components is also realized, significantly improving the versatility and positioning accuracy of the fixture.

[0027] like Figure 4 and Figure 5As shown, the riser clamping assembly 5 includes a clamping mounting frame 5-1 mounted on the height adjustment assembly 4. The clamping mounting frame 5-1 is the basic structure supporting the entire clamping assembly; it can be a metal frame or a high-strength plastic frame, providing a stable mounting platform for other components. Fixed clamping wheels 5-7 are rotatably connected to the lower part of the clamping mounting frame 5-1. These fixed clamping wheels 5-7 are rotating components serving as basic support points; they can be bearing-type rollers or bushing-type rollers, reducing horizontal swaying of the curved connecting pipe. The assembly also includes several longitudinally arranged clamping guide rails 5-4 fixed to the clamping mounting frame 5-1. A lifting mounting seat 5-5 is slidably connected to the clamping guide rails 5-4 via sliders. In practical applications, the clamping guide rails 5-4 are guide components used to guide the movement trajectory of the lifting mounting seat 5-5; they can be linear guide rails or dovetail guide rails, ensuring the lifting mounting seat 5-5 maintains a stable trajectory during movement.

[0028] Two movable clamping wheels 5-6, symmetrically arranged with respect to the fixed clamping wheel 5-7, are rotatably connected to the lifting mounting base 5-5. Both the movable clamping wheels 5-6 and the fixed clamping wheel 5-7 are V-groove rollers arranged in a triangular pattern. The movable clamping wheels 5-6 are rotating components whose position can be adjusted as needed; they can be adjustable rollers or elastic clamping rollers to accommodate arc-shaped connecting pipes of different diameters. A linear drive component 5-2 is also included, mounted on the clamping mounting frame 5-1. The extended end of the linear drive component 5-2 is connected to the lifting mounting base 5-5. The linear drive component 5-2 is a power device used to drive the movement of the lifting mounting base 5-5; it can be a cylinder, hydraulic cylinder, or electric push rod, designed to precisely control the clamping force.

[0029] The riser clamping assembly 5 also includes a plurality of paired clamping wheel mounting holes 5-8 on the lifting mounting base 5-5 for mounting two movable clamping wheels 5-6. The spacing between the two clamping wheel mounting holes 5-8 in each pair gradually increases from bottom to top. Specifically, the clamping wheel mounting hole 5-8 refers to the positioning hole for mounting the movable clamping wheel 5-6, which can be in the form of a threaded hole or a pin hole, with the purpose of matching curved connecting pipes with different curvatures.

[0030] In detail, the above setup, by mounting the clamping mounting bracket 5-1 on the height adjustment component 4, allows the entire clamping assembly to be flexibly adjusted according to the longitudinal position of the buoy structure. The fixed clamping wheel 5-7 is rotatably connected to the lower part of the clamping mounting bracket 5-1, serving as a basic support point and providing a stable clamping reference. The clamping guide rail 5-4 is longitudinally positioned and connected to the lifting mounting base 5-5 via a slider, ensuring that the lifting mounting base 5-5 maintains a smooth trajectory during movement. Two movable clamping wheels 5-6, rotatably connected to the lifting mounting base 5-5, are symmetrically arranged about the fixed clamping wheel 5-7, forming a three-point constraint structure, ensuring that the clamping force is evenly applied to the surface of the curved connecting pipe. Both movable clamping wheels 5-6 and the fixed clamping wheel 5-7 employ a V-groove roller design; when the diameter of the curved connecting pipe changes, the rollers can automatically slide along the groove to adjust the contact point. A linear drive component 5-2 is mounted on the clamping mounting bracket 5-1, with its extended end connected to the lifting mounting base 5-5. The distance between the movable clamping wheel 5-6 and the fixed clamping wheel 5-7 is dynamically adjusted by driving the lifting mounting base 5-5 to move. The spacing between the paired clamping wheel mounting holes 5-8 on the lifting mounting base 5-5 gradually increases from bottom to top. When the movable clamping wheel 5-6 is installed in mounting holes at different heights, the lateral distance between the two movable clamping wheels 5-6 is adjusted accordingly, thereby matching the curved connecting pipes with different curvatures.

[0031] The above technical solution enables precise clamping and adaptive positioning of the arc-shaped connecting pipe, effectively solving the positioning deviation problem caused by differences in diameter and curvature during clamping, and ensuring the stability and accuracy of the welding process.

[0032] See further Figure 4 The height adjustment component 4 includes an adjustment guide 4-1, which is mounted on the centering top plate 2-2 in the centering drive component 2. The height adjustment component 4 also includes a mounting support 4-4 with a longitudinally extending adjustment groove 4-3. Two guide slide plates 4-2 with an L-shaped structure and opposite arrangement are mounted on the mounting support 4-4. The adjustment guide 4-1 slides through the groove formed by the two guide slide plates 4-2. The adjustment guide 4-1 and the mounting support 4-4 are locked together by a locking knob that passes through the adjustment groove 4-3.

[0033] Specifically, this design utilizes two opposing L-shaped guide slide plates 4-2 on the mounting support 4-4, forming a closed-loop groove structure. This allows the mounting support 4-4 to move precisely vertically under the clamping guidance of the two L-shaped guide slide plates 4-2. The design of the adjusting longitudinal groove 4-3 allows the operator to fix the locking knob at any desired height according to actual welding needs, thereby achieving precise positioning of the riser clamping assembly 5. When the mounting support 4-4 moves longitudinally, the geometric characteristics of the L-shaped guide slide plates 4-2 effectively restrict its lateral freedom, reducing unnecessary frictional resistance. By tightening the locking knob, a rigid connection is formed between the adjusting guide 4-1 and the mounting support 4-4. This connection effectively resists vibration interference generated during welding, ensuring the positional stability of the arc-shaped connecting pipe 7-5 during welding. Furthermore, this structural design, in conjunction with the riser clamping assembly 5, enhances the accuracy, reliability, and versatility of communication buoy welding.

[0034] like Figure 3 As shown, the drive seat structure includes a centering top plate 2-2 and a centering seat plate 2-1 arranged vertically in a cross shape. Several connecting columns are provided between the centering top plate 2-2 and the centering seat plate 2-1 to connect them as a single unit. Several movable grooves 2-7 extending along the length direction are provided at two opposite ends of the centering top plate 2-2, and several strip-shaped through slots 2-6 extending along the length direction are provided at the other two opposite ends of the centering top plate 2-2. The movable grooves 2-7 and the strip-shaped through slots 2-6 are arranged vertically. Two movable seats 1 2-5 are connected to the lead screw drive mechanism via support plates passing through the corresponding strip-shaped through slots 2-6. Two movable seats 2-8 are slidably connected to the centering top plate 2-2 via sliders that slide through the corresponding movable grooves 2-7. Both movable seats 2-8 are locked by locking knobs that slide through the movable grooves 2-7 and engage with the sliders.

[0035] Specifically, the centering top plate 2-2 refers to a support component with a specific geometric shape, which can be processed from high-strength metal sheet, and its purpose is to provide a stable installation platform. The movable groove 2-7 can be understood as a guide structure, specifically formed into a straight groove through machining, and its purpose is to guide the sliding trajectory of the movable seat 2-8. In practical applications, the strip-shaped through-hole 2-6 refers to a long strip-shaped through-hole structure, which can be precisely machined using CNC machine tools, and its purpose is to provide movement space for the support plate. Furthermore, the connecting column is a rod-shaped structure that serves both connecting and supporting functions, and can be fixedly connected to the centering top plate 2-2 and the centering seat plate 2-1 through threaded connections or welding.

[0036] In detail, the above-mentioned setup forms a stable support system through a cross-shaped structural frame consisting of a centering top plate 2-2 and a centering base plate 2-1. The movable slide groove 2-7 and the strip-shaped through-slot 2-6 on the centering top plate 2-2 are arranged perpendicularly to each other, ensuring that movements in two directions do not interfere with each other. Movable base one 2-5 is connected to the lead screw drive mechanism via a support plate; this connection allows movement within the strip-shaped through-slot 2-6, ensuring precise displacement control. Movable base two 2-8 slides within the movable slide groove 2-7 via a slider; the cooperation between the slider and the locking knob ensures both smooth movement and reliable fixation after positioning. This structural design effectively solves the problem of easy offset and wobbling of the movable base during adjustment, especially maintaining the precise positioning of the buoy base plate during welding, thereby improving the welding accuracy and yield of the communication buoy. Through the above technical solution, not only is a high-precision guiding function achieved, but a reliable locking capability is also provided, fundamentally guaranteeing welding quality.

[0037] like Figure 3 As shown, the lead screw drive mechanism includes several centering guide rails 2-3 fixed to the centering base plate 2-1 and arranged parallel to the strip groove 2-6; two sets of movable mounting seats are slidably connected to the several centering guide rails 2-3 via sliders; several support plates are fixedly connected to the two sets of movable mounting seats respectively; it also includes a forward and reverse rotary lead screw 2-10 rotatably connected to the centering base plate 2-1 and arranged parallel to the centering guide rails 2-3; the two sets of movable mounting seats are respectively connected to the forward and reverse rotary lead screw 2-10 via corresponding nuts; and a lead screw drive component 2-4 is installed at the end of the forward and reverse rotary lead screw 2-10.

[0038] In practical applications, the centering guide rail 2-3 refers to the structure that provides a precise guiding path for the movable mounting base. It can be implemented using structures with high guiding accuracy, such as linear guide rails or dovetail guide rails. Its purpose is to ensure that the movable mounting base maintains a strictly straight trajectory during movement, avoiding deviation. The forward and reverse rotating screw 2-10 can be understood as a specially designed transmission element, characterized by opposite thread directions on both sides. This design enables the movable mounting bases at both ends to move synchronously in opposite directions, eliminating the risk of asynchrony and ensuring uniform force application to the buoy base plate by the two movable bases 2-5. Specifically, the screw drive component 2-4 refers to the power device used to drive the rotation of the forward and reverse rotating screw 2-10. It can be implemented using a manual crank, servo motor, or stepper motor, aiming to provide a convenient operating interface and precise control capabilities.

[0039] When the lead screw drive component 2-4 drives the forward and reverse rotating lead screws 2-10 to rotate, the opposite threads on both sides of the lead screw cause the two sets of movable mounting seats to automatically generate synchronous reverse displacement. This movement is directly transmitted to the movable seat 2-5 through the support plate, thereby driving the two movable seats 2-5 to achieve uniform clamping of the buoy base plate 7-1. This structural design, in conjunction with other components in the aforementioned communication buoy welding fixture, effectively solves the problems of skewing and jamming caused by the lack of precise guidance and synchronization mechanisms, significantly improving the accuracy and stability of centering and clamping, and providing a reliable guarantee for the precise welding of communication buoys.

[0040] like Figure 3 As shown, several clamping rollers 2-9 are rotatably connected to each movable seat 2-5 and each movable seat 2-8 for centering and clamping the buoy base plate 7-1. The clamping rollers 2-9 are evenly distributed along the edge of the V-groove on the movable seat. The design of the clamping rollers 2-9 allows for rotatable connection through structures such as bearings with bushings, self-lubricating bushings, or rolling bearings, reducing frictional resistance while ensuring smooth adjustment of the buoy base plate 7-1. The even distribution of the clamping rollers along the edge of the V-groove means that multiple rollers are arranged at equal intervals along the continuous edge of the V-groove. This distribution can be achieved by setting equidistant positioning holes or marks during manufacturing, aiming to evenly transmit the clamping force to the entire contact surface of the buoy base plate.

[0041] By creating a V-groove at the inner end of the moving seat, a clear installation reference is provided for the clamping rollers. The geometric characteristics of the V-groove not only define the installation position of the rollers but also generate a centripetal force during clamping through the inclined structure of the V-groove, guiding the buoy seat plate to automatically move towards the center, thereby improving the initial positioning accuracy. The uniform distribution of several clamping rollers along the edge of the V-groove ensures that they are evenly spaced in the circumferential direction. This design eliminates local stress concentration and ensures that the pressure on each roller remains consistent. Based on the above structure, when the centering drive assembly 2 moves the moving seat, it can effectively prevent the buoy seat plate 7-1 from twisting or shifting due to uneven force. When used in conjunction with the lead screw drive mechanism, it can further ensure the stability of the annular buoy seat plate throughout the clamping process, significantly improving the accuracy of welding positioning.

[0042] The above settings enable stable and reliable clamping of the annular buoy base plate, solving the problem of base plate deformation caused by uneven clamping force distribution in traditional solutions, and providing a strong guarantee for the precise welding of communication buoys.

[0043] like Figure 4 and Figure 5As shown, the riser clamping assembly 5 also includes a union seat 5-3 installed on the lifting mounting base 5-5. An opening groove is provided on the union seat 5-3, and a union is engaged in the opening groove. The extended end of the linear drive member 5-2 is connected to the union.

[0044] Specifically, the union seat 5-3 refers to an intermediate structural component with flexible connection function. It can be made of metal or high-strength engineering plastic and is fixed to the lifting mounting seat 5-5 by bolts, welding or other detachable methods. Its purpose is to provide a structural foundation for subsequent flexible adaptation. The opening slot can be understood as a groove structure with a specific geometric shape, such as a U-shaped groove, a V-shaped groove or other adaptable shape. Its purpose is to allow the union to make fine adjustments to the angle within the groove, thereby alleviating the problem of rigid stress concentration. In practical applications, the union is a connector that can realize multi-degree-of-freedom movement. It can be realized through ball joints, universal joints or other flexible connection forms. Its purpose is to absorb welding vibration and impact energy through flexible connection to ensure clamping stability.

[0045] like Figure 5 As shown, a clearance groove 5-9 corresponding to the fixed clamping wheel 5-7 is provided in the middle of the lower end of the lifting mounting base 5-5, which is used to avoid the fixed clamping wheel 5-7 when the lifting mounting base 5-5 moves downward.

[0046] The clearance slot 5-9 refers to a specific spatial structure opened in the middle of the lower end of the lifting mounting base 5-5. It can be achieved by machining methods such as milling or wire cutting to form a through slot on the lifting mounting base 5-5. Its purpose is to provide sufficient clearance space for the fixed clamping wheel 5-7, preventing interference between the two during relative movement. The corresponding setting means that the position and dimensions of the clearance slot 5-9 match the installation position and outer contour of the fixed clamping wheel 5-7. This can be achieved through precise measurement and positioning machining, ensuring that the normal operation of the fixed clamping wheel 5-7 is not affected during the movement of the lifting mounting base 5-5. In detail, by opening the clearance slot 5-9 in the middle of the lower end of the lifting mounting base 5-5, when the linear drive component 5-2 drives the lifting mounting base 5-5 downwards, the fixed clamping wheel 5-7 can smoothly pass through the slot, effectively avoiding rigid collisions caused by structural overlap.

[0048] Mounting bracket 1 serves as the basic support structure for the entire tooling, providing a stable platform for the installation and coordinated operation of other components. Two vertical plate positioning components 1 (3) and two vertical plate positioning components 2 (6) are movably connected to mounting bracket 1, used to position and install the four sets of mounting vertical plates 7-3. Through this movable connection, the positions of the two vertical plate positioning components 1 (3) and two vertical plate positioning components 2 (6) can be flexibly adjusted according to actual needs, thereby ensuring that the four sets of mounting vertical plates 7-3 maintain a precise spatial distribution during welding, avoiding welding misalignment caused by inaccurate positioning.

[0049] Furthermore, the centering drive assembly 2 installed on the mounting bracket 1 is used to center and clamp the buoy base plate 7-1. Two movable seats 2-5 and two movable seats 2-8 are arranged opposite each other and are respectively connected to the upright plate positioning assembly 3 and the upright plate positioning assembly 6. Each upright plate positioning assembly is installed on its corresponding movable seat, allowing the upright plate positioning assembly to move synchronously with the movable seat, thereby achieving coordinated positioning between the mounting upright plate 7-3 and the buoy base plate 7-1.

[0050] Specifically, V-grooves are formed at the inner ends of each of the movable seats 2-5 and 2-8, and several clamping rollers 2-9 are rotatably connected to them. These clamping rollers 2-9 are used to center and clamp the buoy base plate 7-1. The inclined structure of the V-grooves naturally guides the buoy base plate towards the center during clamping, and the centripetal force generated by the inclined surface assists in achieving automatic centering. The design of the clamping rollers 2-9 not only reduces frictional resistance but also facilitates smooth adjustment and uniform force distribution of the buoy base plate 7-1, thereby ensuring the accuracy of centering and clamping. In addition, the screw drive mechanism installed on the drive seat structure can drive the two movable seats 2-5 or the two movable seats 2-8 to move synchronously in opposite directions. Through this precise synchronous drive mechanism, the two movable seats 2-5 or the two movable seats 2-8 can move in coordination, enabling the buoy base plate 7-1 to quickly and accurately reach the center position, avoiding welding errors caused by center offset.

[0051] Meanwhile, the riser clamping assembly 5 is used to clamp the arc-shaped connecting pipe 7-5, while the height adjustment assembly 4 is used to adjust the longitudinal position of the riser clamping assembly 5. The height adjustment assembly 4 adaptively adjusts the height of the riser clamping assembly 5 to ensure that the arc-shaped connecting pipe 7-5 can be reliably clamped and fixed at different heights and for different models, preventing shaking or displacement during welding. Thus, through the coordinated operation of its components, the entire system achieves precise positioning and reliable fixing of each part of the communication buoy during the welding process, effectively solving the problems of large welding errors and low yield caused by the lack of positioning measures.
