Description

Technical Field

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

[0002] A tethering frame is a device used to fix or restrict the movement of objects, commonly found in aviation, environmental monitoring, agriculture, and other fields. Specifically, a tethering frame is a support or platform with a "tethering" (i.e., securing, fixing) function. It connects an aircraft to the ground via a tethering cable, thereby enabling continuous power supply and high-speed data transmission to the aircraft while restricting its range of motion within the length of the cable.

[0003] There is a type of tethering frame 5, such as Figure 7 As shown, the tethering frame 5 includes an annular base plate 5-7. Several supporting vertical pipes 5-10, evenly distributed along its circumference, are fixed to the annular base plate 5-7. At the center of the area enclosed by the supporting vertical pipes 5-10, an intermediate cylindrical member 5-4 is arranged coaxially with the through hole 5-1. Diagonal connecting pipes 5-9 and transverse connecting pipes 5-5, distributed vertically, are fixed between the intermediate cylindrical member 5-4 and each supporting vertical pipe 5-10. Furthermore, two of the supporting vertical pipes 5-10 are selected and fixed with transversely arranged vertical pipe connecting plates 5-6, and the two supporting vertical pipes 5-10 are adjacent to each other. Several mounting holes are provided on the riser connecting plate 5-6; two sets of mounting side plates 5-2 are fixed to the outer peripheral wall of the intermediate cylinder 5-4 and are evenly distributed along its circumference, and several mounting through holes are provided on each mounting side plate 5-2; it also includes a hoisting component 5-11 fixed to the closed end of the intermediate cylinder 5-4; in addition, several through holes 5-8 are provided on the annular base plate 5-7 and are evenly distributed along its circumference, and mounting through holes corresponding to the positions of the riser connecting plate 5-6 are provided on the annular base plate 5-7, and several through holes 5-13 are evenly distributed along the circumference of the above-mentioned mounting through holes.

[0004] Before welding the aforementioned tethering frame, each component of the tethering frame needs to be positioned separately. Existing technology generally involves placing each component of the tethering frame 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 of tethering frames. Therefore, it is urgent to design a welding fixture specifically for tethering frames to solve the above problems and achieve precise welding operations for tethering frames. Summary of the Invention

[0005] This utility model provides a welding fixture for tethered frames with a reasonable structural design to solve the technical problems existing in the prior art. This utility model solves the problems of inaccurate component positioning and easy displacement during the welding process of tethered frames, and can accurately ensure the perpendicularity of the supporting upright pipe to the annular base plate, the consistency of the spatial angle between the transverse connecting pipe and the oblique connecting pipe, and the coaxiality of the intermediate cylinder and each connecting component, thereby improving the quality of the welded joint, enhancing the overall structural stability, and increasing assembly efficiency.

[0006] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is as follows: A welding fixture for a tethering frame includes a support and positioning assembly. A first circumferential positioning assembly and a second circumferential positioning assembly are arranged opposite to each other above the support and positioning assembly. A hoisting and positioning assembly is also provided between the first and second circumferential positioning assemblies. The support and positioning assembly includes a base frame mechanism for supporting an annular base plate. A cylinder support mechanism for supporting an intermediate cylinder is fixedly connected to the center of the base frame mechanism. Several positioning ends that engage with several through holes are provided at the top of the cylinder support mechanism. The bottom edge of the cylinder support mechanism is arc-shaped and engages with the central hole of the annular base plate. The first circumferential positioning assembly includes a first vertical pipe support mechanism detachably connected to the annular base plate. Several positioning ends that engage with several supporting vertical pipes are provided on the first vertical pipe support mechanism. The system includes: an arc groove 1; a plurality of connecting pipe rack units 1 fixedly connected to the riser frame mechanism 1 for clamping and positioning a plurality of transverse connecting pipes and a plurality of oblique connecting pipes; a circumferential positioning component 2 including a riser frame mechanism 2 detachably connected to an annular base plate, and a plurality of positioning arc grooves 2 formed on the riser frame mechanism 2 for engaging with a plurality of supporting risers; a plurality of connecting pipe rack units 2 fixedly connected to the riser frame mechanism 2 for clamping and positioning a plurality of transverse connecting pipes and a plurality of oblique connecting pipes, and a connecting plate positioning plate fixedly connected to the riser frame mechanism 2 for positioning the riser connecting plate; and a hoisting positioning component including a hoisting unit 1 and a hoisting unit 2 detachably connected to the intermediate cylinder and arranged symmetrically about the intermediate cylinder with identical structures for positioning two mounting side plates, and a plurality of mounting studs for connecting the upper ends of the hoisting unit 1 and the hoisting unit 2 for clamping the hoisting component.

[0007] The advantages and positive effects of this utility model are as follows: This utility model provides a welding fixture for a tethering frame. By combining a support positioning component, a first circumferential positioning component, a second circumferential positioning component, and a hoisting positioning component in a multi-level positioning system, precise spatial constraints on each component of the tethering frame are achieved. Compared with the existing technology that relies solely on a workbench for simple placement and positioning, this embodiment establishes the overall coordinate system foundation through a base frame mechanism, uses positioning arc grooves one and two to precisely engage the support uprights, and simultaneously uses an arc groove structure to provide dual constraints on the angle and position of the transverse and oblique connecting pipes. The hoisting positioning component completes the symmetrical constraint of the top structure, ultimately forming a full-dimensional positioning chain from the base plate to the top component.

Detailed Implementation

[0017] To further understand the invention content, features, and effects of this utility model, the following embodiments are provided in detail: Please see Figure 1 and Figure 2 The tethering frame welding fixture of this utility model includes a support and positioning component 1, and two circumferential positioning components 2 and 4 are arranged opposite to each other above the support and positioning component 1. It also includes a hoisting positioning component 3 arranged between the circumferential positioning components 2 and circumferential positioning components 4. The aforementioned support and positioning assembly 1 includes a base frame mechanism 1-1 for supporting the annular base plate 5-7, a cylinder support mechanism 1-2 for supporting the intermediate cylinder 5-4 fixed at the center of the base frame mechanism 1-1, and a plurality of positioning ends 1-2-3 that are inserted into and cooperate with a plurality of through holes 5-3 at the top of the cylinder support mechanism 1-2. The bottom edge of the cylinder support mechanism 1-2 is arc-shaped and engages with the central hole of the annular base plate 5-7.

[0018] Furthermore, the circumferential positioning component 2 includes a riser mechanism 2-1 detachably connected to the annular base plate 5-7. The riser mechanism 2-1 has several positioning arc grooves 2-1-1 that engage with several supporting risers 5-10. Several connecting pipe units 2-2 are fixedly connected to the riser mechanism 2-1 for clamping and positioning several transverse connecting pipes 5-5 and several oblique connecting pipes 5-9. Additionally, the circumferential positioning component 4 includes components that are detachably connected to the annular base plate 5-7. 5-7 The detachable riser mechanism 2 4-1 has several positioning arc grooves 2 4-1-1 that engage with several supporting risers 5-10; several connecting pipe units 2 4-2 are fixedly connected to the riser mechanism 2 4-1 for clamping and positioning several horizontal connecting pipes 5-5 and several oblique connecting pipes 5-9; it also includes a connecting plate positioning plate 4-3 fixedly connected to the riser mechanism 2 4-1 for positioning the riser connecting plate 5-6; Furthermore, the aforementioned hoisting and positioning assembly 3 includes a hoisting unit 1 3-1 and a hoisting unit 2 3-3 that are detachably connected to the intermediate cylinder 5-4 and are centrally symmetrical about the intermediate cylinder 5-4 and have the same structure, for positioning the two mounting side plates 5-2. A plurality of mounting studs 3-2 for connecting the upper ends of the two are installed between the hoisting unit 1 3-1 and the hoisting unit 2 3-3 for clamping the hoisting component 5-11.

[0019] The support and positioning component 1 can be understood as a structure that provides a basic positioning reference. Its base frame mechanism 1-1 can achieve stable support for the annular base plate 5-7 in various ways, such as using a frame structure or a flat plate structure, and enhancing stability by adding counterweights or setting anti-slip pads. The arc-shaped bottom of the cylindrical support mechanism 1-2 engages with the center hole of the annular base plate 5-7. This engagement method can further enhance the positioning effect by setting elastic buckles or magnetic adsorption devices.

[0020] See further Figure 3The aforementioned cylindrical support mechanism 1-2 includes a support base plate 1-2-1 fixed at the center of the base frame mechanism 1-1. The outer edge of the support base plate 1-2-1 is arc-shaped and engages with the central hole of the annular base plate 5-7. A plurality of longitudinally arranged positioning rods 1-2-2 are fixedly connected to the support base plate 1-2-1. The mechanism also includes a support top plate 1-2-4 that connects the plurality of positioning rods 1-2-2 into one unit. The support top plate 1-2-4 has slots that engage with the plurality of positioning rods 1-2-2. The upper ends of the plurality of positioning rods 1-2-2 located above the support top plate 1-2-4 constitute a plurality of positioning ends 1-2-3.

[0021] By optimizing the structure of the cylinder support mechanism 1-2, the problem of inaccurate positioning of the intermediate cylinder 5-4 is effectively solved. The outer edge of the support base plate 1-2-1 is designed as an arc and engages with the center hole of the annular base plate 5-7, ensuring the radially accurate positioning of the cylinder support mechanism 1-2 on the base frame mechanism 1-1. This avoids the tilting of the intermediate cylinder 5-4 due to installation position offset. Simultaneously, the arc-shaped engagement adapts to the contour of the center hole of the annular base plate 5-7, enhancing the stability of the connection. The positioning uprights 1-2-2 are longitudinally set and fixed to the support base plate 1-2-1, providing uniform vertical support force. This ensures even force distribution on the intermediate cylinder 5-4 during placement, preventing deformation or displacement caused by uneven local pressure, and maintaining structural rigidity, especially under welding thermal stress. The support top plate 1-2-4, through its slotted holes and tight engagement with the positioning uprights 1-2-2, not only strengthens the overall integrity between the positioning uprights 1-2-2 but also significantly improves the torsional resistance of the entire cylinder support mechanism 1-2.

[0022] The positioning end 1-2-3 is directly formed by the upper end of the positioning upright 1-2-2, and it forms an insertion fit with the through hole 5-3 of the intermediate cylinder 5-4. This integrated design simplifies the assembly process while ensuring positioning accuracy. Based on the above structural design, when used in conjunction with the support positioning component 1, it can effectively prevent the intermediate cylinder 5-4 from shaking or shifting during the welding process, thereby ensuring the accuracy of the welding position and improving the overall assembly accuracy and welding quality of the tethering frame.

[0023] like Figure 3As shown, the base frame mechanism 1-1 includes a long profile 1-1-1, and two sets of short profiles 1-1-2 are fixedly connected to the middle of the long profile 1-1-1. The long profile 1-1-1 and the two sets of short profiles 1-1-2 form a cross-shaped structure. A mounting hole is opened in the middle of the long profile 1-1-1, and a through hole is opened in the middle of the support base plate 1-2-1, which is coaxial with the mounting hole opened on the long profile 1-1-1, for positioning the cylinder support mechanism 1-2 and the base frame mechanism 1-1. Four sets of positioning uprights 1-2-2 are provided, and the four sets of positioning uprights 1-2-2 are evenly distributed along the circumference. The support top plate 1-2-4 has a cross-shaped structure.

[0024] The cross-shaped structure design of the base frame mechanism 1-1 solves the support stability problem. Based on the cross-shaped layout formed by the long profile 1-1-1 and two sets of short profiles 1-1-2, the base frame mechanism 1-1 effectively distributes the dynamic load during welding operations, prevents structural twisting, provides a solid foundation for the cylinder support mechanism 1-2, and avoids vibration transmission caused by uneven local stress. Due to the coaxial arrangement of the mounting hole in the middle of the long profile 1-1-1 and the through hole in the support base plate 1-2-1, the cylinder support mechanism 1-2 and the base frame mechanism 1-1 achieve precise alignment and positioning, ensuring the accurate positioning of the intermediate cylinder 5-4 during installation and avoiding positioning deviations caused by assembly errors. This ensures the reliable insertion and mating of the intermediate cylinder 5-4 and the cylinder support mechanism 1-2.

[0025] Further details not available. Figure 4 The aforementioned riser mechanism 2-1 includes a positioning top plate 2-1-3 and a positioning bottom plate 2-1-2 arranged vertically. A plate support rod 2-1-4 is provided between the positioning top plate 2-1-3 and the positioning bottom plate 2-1-2 to fix them together. Four positioning arc grooves 2-1-1 are provided, and the four positioning arc grooves 2-1-1 are respectively opened at both ends of the positioning top plate 2-1-3 and the positioning bottom plate 2-1-2. The 2-1-1 are arranged in pairs, with the two positioning arc grooves 2-1-1 in each pair distributed vertically and coaxially; a number of positioning mounting holes 2-1-5 are opened on the positioning base plate 2-1-2, and the number of positioning mounting holes 2-1-5 are respectively set to correspond to the number of through holes 5-8 opened on the annular base plate 5-7. The riser mechanism 2-1 is locked to the annular base plate 5-7 by bolts and lock nuts passing through the positioning mounting holes 2-1-5.

[0026] Specifically, this scheme effectively avoids the tilting risk that may be caused by single-point positioning by using a dual vertical constraint benchmark formed by the positioning top plate 2-1-3 and the positioning bottom plate 2-1-2. The plate support rod 2-1-4 rigidly connects the top and bottom plates, significantly improving the overall structure's resistance to deformation and ensuring stability during welding. The four positioning arc grooves 2-1-1 are arranged in pairs, vertically distributed, and coaxially. Through the synergistic effect of the upper and lower arc grooves, each support riser achieves coaxial double-point clamping, ensuring not only that the support riser axis is consistent with the design position but also eliminating local stress concentration through evenly distributed positioning points. The positioning mounting hole 2-1-5 precisely corresponds to the through hole 5-8 on the annular bottom plate 5-7, achieving a rapid alignment mechanism and providing a reliable benchmark for welding. The bolt and lock nut connection method ensures both connection strength and disassembly capability, adapting to the need for reusable tooling.

[0027] Based on this, when the aforementioned riser mechanism 2-1 is used in conjunction with the support positioning component 1, a more complete positioning system can be formed. The positioning top plate 2-1-3 and the positioning bottom plate 2-1-2, together with the cylinder support mechanism 1-2, construct a positioning benchmark in three-dimensional space, ensuring reliable constraint of the support riser in all directions. The plate support rod 2-1-4 and the positioning upright rod 1-2-2 of the cylinder support mechanism 1-2 complement each other, forming a stable frame structure that effectively resists external force interference during the welding process. This structural design not only solves the problem of possible displacement or shaking of the support riser during welding, but also significantly improves the overall structural accuracy and welding quality of the mooring frame through multiple positioning and reinforcement measures.

[0028] like Figure 4 As shown, the pipe support unit 2-2 has two sets, and the two sets of pipe support units 2-2 are symmetrically arranged about the center line of the riser mechanism 2-1. The pipe support unit 2-2 includes a support plate 2-2-1 fixed to the riser mechanism 2-1. An upper support block 2-2-2 and a lower support block 2-2-3 are installed on the support plate 2-2-1, which are distributed vertically. The upper support block 2-2-2 has a cutting edge for supporting inclined... The connecting pipe 5-9 has an arc-shaped groove that fits its outer peripheral wall, and the acute angle between the axial direction and the vertical direction of the arc-shaped groove is 60°; an arc-shaped groove for supporting the transverse connecting pipe 5-5 and fitting its outer peripheral wall is provided on the lower support block 2-2-3, and the angle between the axial direction and the vertical direction of the arc-shaped groove is 90°; threaded holes pointing radially towards the arc-shaped groove are provided on both the upper support block 2-2-2 and the lower support block 2-2-3, and bolts are screwed into the threaded holes to tighten them.

[0029] Furthermore, the axial extension lines of the arc-shaped grooves on the two upper support blocks 2-2-2 intersect the longitudinal center line of the cylinder support mechanism 1-2, and the projections of the axes of the two upper support blocks 2-2-2 in the horizontal plane are perpendicular to each other; similarly, the axial extension lines of the arc-shaped grooves on the two lower support blocks 2-2-3 in the two connecting pipe support units 2-2 intersect the longitudinal center line of the cylinder support mechanism 1-2, and the axes of the two lower support blocks 2-2-3 are perpendicular to each other in the horizontal plane. By precisely defining the axial geometric relationship of the arc-shaped grooves of the support blocks, the oblique connecting pipe 5-9 and the transverse connecting pipe 5-5 are ensured to achieve correct spatial positioning during welding, avoiding welding errors caused by positional deviations.

[0030] Specifically, the pipe support unit 2-2 refers to a structural component specifically designed for positioning and fixing the horizontal pipes 5-5 and the inclined pipes 5-9. It can be implemented using a symmetrical layout, layered design, and angle matching. The support plate 2-2-1 is a connecting base that can be rigidly connected to the riser mechanism 2-1 via welding or bolting, providing a stable support foundation. The upper support block 2-2-2 and lower support block 2-2-3 correspond to pipes at different positions. Their layered design avoids mutual interference between pipes while ensuring precise vertical positioning. The arc-shaped groove design is optimized based on the actual inclination angle of the pipes, aiming to reduce local stress concentration and improve positioning stability through surface contact support. The tightening bolts are used to apply radial pressure after the pipes are placed, effectively suppressing thermal deformation or radial rolling that may occur during welding.

[0031] like Figure 5 As shown, the structure of the above-mentioned riser mechanism 2 4-1 is similar to that of the riser mechanism 1 2-1. It mainly includes a positioning top plate 2 4-1-3 and a positioning bottom plate 2 4-1-2 arranged correspondingly at the top and bottom. A plate support rod 2 4-1-4 is provided between the positioning top plate 2 4-1-3 and the positioning bottom plate 2 4-1-2 to fix the two together. There are four positioning arc grooves 2 4-1-1, and the four positioning arc grooves 2 4-1-1 are respectively opened at both ends of the positioning top plate 2 4-1-3 and the positioning bottom plate 2 4-1-2. The four positioning arc grooves 2 4-1-1 are arranged in pairs, and the two positioning arc grooves 2 4-1-1 in each pair are distributed vertically and arranged coaxially. A positioning pin hole 4-1-6 is provided on the positioning base plate 2 4-1-2, which corresponds to the through hole 5-13 on the annular base plate 5-7. The riser mechanism 2 4-1 and the annular base plate 5-7 are positioned by a pin that passes through the positioning pin hole 4-1-6. Several positioning mounting holes 4-1-5 are provided on the positioning base plate 4-1-2. The several positioning mounting holes 4-1-5 are respectively set to correspond to several through holes 5-8 provided on the annular base plate 5-7. The riser mechanism 4-1 is locked to the annular base plate 5-7 by bolts and lock nuts passing through the positioning mounting holes 4-1-5. It also includes a connecting plate positioning plate 4-3 fixed to the plate support rod 4-1-4. The connecting plate positioning plate 4-3 has several through holes corresponding to several mounting holes on the riser connecting plate 5-6, which are used to lock and connect the riser connecting plate 5-6.

[0032] The working principle of riser mechanism 2 4-1 is the same as that of riser mechanism 1 2-1. The difference lies in the introduction of a pin that directly matches the through hole 5-13 on the annular base plate 5-7, which is used for the installation of the tie frame 5. This ensures the absolute positional fixation of riser mechanism 2 4-1 in critical areas. The connecting plate positioning plate 4-3 is fixed to the plate support rod 2 4-1-4, and its through hole corresponds to the mounting hole of the riser connecting plate 5-6, used to directly lock the riser connecting plate 5-6. This ensures the precise alignment of the riser connecting plate 5-6 with the supporting riser 5-10 during welding, reducing assembly stress caused by positional deviations and thus improving welding quality. Overall, the synergistic effect of pin positioning and bolt locking not only solves the defect of inaccurate positioning but also adapts to the special positional requirements of the riser connecting plate 5-6 in the tie frame 5 structure, laying a high-precision foundation for subsequent welding steps.

[0033] like Figure 5As shown, the pipe support unit 2 4-2 is provided in two sets, and the two sets of pipe support unit 2 4-2 are symmetrically arranged about the center line of the riser mechanism 2 4-1. The pipe support unit 2 4-2 includes a support plate 2 4-2-1 fixed to the riser mechanism 2 4-1. An upper support block 2 4-2-2 and a lower support block 2 4-2-3 distributed vertically are installed on the support plate 2 4-2-1. The upper support block 2 4-2-2 has a cutting edge for supporting inclined... The connecting pipe 5-9 has an arc-shaped groove that fits its outer peripheral wall, and the acute angle between the axial direction and the vertical direction of the arc-shaped groove is 60°; an arc-shaped groove for supporting the transverse connecting pipe 5-5 and fitting its outer peripheral wall is provided on the lower support block 4-2-3, and the angle between the axial direction and the vertical direction of the arc-shaped groove is 90°; threaded holes pointing radially towards the arc-shaped groove are provided on both the upper support block 4-2-2 and the lower support block 4-2-3, and bolts are screwed into the threaded holes to tighten them. Furthermore, the axial extension lines of the arc-shaped grooves opened on the two upper support blocks 4-2-2 intersect the longitudinal center line of the cylinder support mechanism 1-2, and the projections of the axes of the two upper support blocks 4-2-2 in the horizontal plane are perpendicular to each other; the axial extension lines of the arc-shaped grooves opened on the two lower support blocks 4-2-3 in the two connecting pipe rack units 4-2 intersect the longitudinal center line of the cylinder support mechanism 1-2, and the axes of the two lower support blocks 4-2-3 are perpendicular to each other in the horizontal plane.

[0034] The working principle of pipe rack unit 2-4-2 is the same as that of pipe rack unit 1-2-2. See further Figure 6 The aforementioned hoisting unit 3-1 includes a hoisting base plate 3-1-5. A base plate positioning hole 3-1-6 corresponding to the through hole 5-1 on the intermediate cylinder 5-4 is provided in the middle of the hoisting base plate 3-1-5. Two base plate positioning shafts 3-1-7 are provided on the hoisting base plate 3-1-5. The two base plate positioning shafts 3-1-7 are respectively inserted into and cooperate with two through holes 5-3 on the same side on the intermediate cylinder 5-4. The hoisting unit 3-1 also includes a longitudinally arranged side plate seat plate 3-1-3 fixedly connected to the hoisting seat plate 3-1-5 for detachably installing the side plate 5-2. The side plate seat plate 3-1-3 has several side plate mounting holes 3-1-4 corresponding to the mounting through holes on the side plate 5-2. A longitudinally arranged tangential positioning plate 3-1-1 is fixedly connected to the inner edge of the side plate seat plate 3-1-3. The tangential positioning plate 3-1-1 and the side plate seat plate 3-1-3 are arranged perpendicularly. When the two seat plate positioning shafts 3-1-7 are inserted into the two through holes 5-3 on the same side of the intermediate cylinder 5-4, the inner side of the tangential positioning plate 3-1-1 is tangentially engaged with the outer peripheral wall of the intermediate cylinder 5-4. An operating slot 3-1-2 is provided at the intersection of the tangential positioning plate 3-1-1 and the side plate seat plate 3-1-3 to facilitate welding operations; in addition, the inner end of the lifting seat plate 3-1-5 is bent upward to form a positioning plate 3-1-8 for clamping the lifting component 5-11, and a through hole for inserting the mounting stud 3-2 is provided on the positioning plate 3-1-8.

[0035] The precise positioning of the mounting side plate 5-2 is achieved through the organic cooperation of various components. First, the lifting base plate 3-1-5 serves as the basic platform, achieving axial fixation through the mating of the base plate positioning hole 3-1-6 with the through hole 5-1 of the intermediate cylinder 5-4. Simultaneously, radial positioning is achieved through the insertion mating of the two base plate positioning shafts 3-1-7 with the through hole 5-3. This dual positioning mechanism ensures the initial installation accuracy of the lifting unit 3-1. Second, the side plate base plate 3-1-3, through its side plate mounting hole 3-1-4, mates with the mounting through hole of the mounting side plate 5-2, enabling rapid installation of the mounting side plate 5-2. The tangential positioning plate 3-1-1, by utilizing the tangential mating of its inner surface with the outer peripheral wall of the intermediate cylinder 5-4, ensures strict alignment of the tangential position of the mounting side plate 5-2. Furthermore, the operating slot 3-1-2 facilitates welding operations, while the positioning upright plate 3-1-8, in conjunction with the mounting stud 3-2, ensures stable clamping of the lifting component 5-11. These components work together to solve the problem of inaccurate positioning of the mounting side plate 5-2, significantly improving welding accuracy and assembly efficiency. Combined with the aforementioned support positioning component 1 and circumferential positioning component, a complete welding positioning system for the tie-down frame is formed, effectively improving the overall welding quality.

[0036] Furthermore, a through groove is provided in the middle of the positioning plate 3-1-8, which connects to its upper edge. This groove can be rectangular, trapezoidal, or other shapes suitable for welding tools. The purpose is to provide a direct operating channel for welding operations, avoiding the obstruction of the positioning plate 3-1-8 solid structure when the welding torch operates in the top area of ​​the intermediate cylinder 5-4, thus making the welding of the connection between the lifting component 5-11 and the intermediate cylinder 5-4 smoother. In addition, two shaft through grooves are provided on the lifting base plate 3-1-5 for engaging the two base plate positioning shafts 3-1-7, and two installation through grooves 3-1-9 are provided on the lifting base plate 3-1-5 respectively, which are connected to the two shaft through grooves.

[0037] The working principle of this utility model is as follows: Through the coordinated operation of the support positioning component 1, the circumferential positioning component 1, the circumferential positioning component 2, and the hoisting positioning component 3, precise positioning and constraint of each component of the tethering frame are achieved. Specifically, the base frame mechanism 1-1 in the support positioning component 1 is used to stably support the annular base plate 5-7, while the cylinder support mechanism 1-2 engages with the center hole of the annular base plate 5-7 through its arc-shaped bottom edge, ensuring the coaxial relationship between the annular base plate 5-7 and the intermediate cylinder 5-4. Furthermore, several positioning ends 1-2-3 at the top of the cylinder support mechanism 1-2 are inserted into the through holes 5-3 on the intermediate cylinder 5-4, thereby achieving precise axial positioning of the intermediate cylinder 5-4. The specific working steps are as follows: Step 1: Place the annular base plate 5-7 on the base frame mechanism 1-1, ensuring that the center hole of the annular base plate 5-7 engages with the lower edge of the cylinder support mechanism 1-2. Then, use the pins passing through the positioning pin holes 4-1-6 and through holes 5-13 to position the riser frame mechanism 4-1 and the annular base plate 5-7. Finally, use bolts and lock nuts passing through through holes 5-8 to lock the circumferential positioning components 4 and 2-1 respectively. On the annular base plate 5-7, four support risers 5-10 are respectively snapped into the several positioning arc grooves 2-1-1 in the circumferential positioning component 2 and the several positioning arc grooves 4-1-1 in the circumferential positioning component 4. Other pressure blocks with horizontal surfaces are used to press down on the support risers 5-10, so that the lower end of the support risers 5-10 is pressed on the top surface of the annular base plate 5-7. The lower end of each support riser 5-10 is spot welded using a welding gun. Step 2: Insert each transverse connecting pipe 5-5 into the arc-shaped grooves opened on several lower support blocks 2-2-3 and several lower support blocks 4-2-3 respectively; then place the intermediate cylinder 5-4 with its opening facing down on the cylinder support mechanism 1-2, so that several positioning ends 1-2-3 on the cylinder support mechanism 1-2 are inserted into several through holes 5-3 opened on the intermediate cylinder 5-4, and ensure that the top surface of the inner cavity of the intermediate cylinder 5-4 is in tight contact with the top surface of the support plate 1-2-4, and adjust each transverse connecting pipe 5-5. This allows the two ends of each horizontal connecting pipe 5-5 to contact the outer wall of the intermediate cylinder 5-4 and the outer wall of the corresponding support riser 5-10, respectively; then each oblique connecting pipe 5-9 is inserted into the arc-shaped grooves opened on several upper support blocks 1 2-2-2 and several upper support blocks 2 4-2-2, so that the two ends of each oblique connecting pipe 5-9 contact the outer wall of the intermediate cylinder 5-4 and the outer wall of the corresponding support riser 5-10, respectively; then the tightening bolts screwed on each support block are used to tighten and lock each connecting pipe. Step 3: Use a welding torch to spot weld the two ends of each horizontal connecting pipe 5-5 and each oblique connecting pipe 5-9. Step 4: Install lifting unit 1 (3-1) and lifting unit 2 (3-3) of the lifting positioning assembly 3 onto the intermediate cylinder 5-4, so that the positioning shafts of the seat plates in the lifting unit 1 (3-1) and lifting unit 2 (3-3) are inserted into the through holes 2 (5-3) opened on the intermediate cylinder 5-4, and use bolts passing through the positioning holes 3-1-6 of the seat plates to lock the lifting positioning assembly 3 and the intermediate cylinder 5-4 together; at this time, the two tangential positioning plates in the lifting positioning assembly 3 are tangent to the outer wall of the intermediate cylinder 5-4, and then install the two mounting side plates 5-2 on the two side plate seat plates respectively, so that the inner ends of the two mounting side plates 5-2 are in contact with the outer wall of the intermediate cylinder 5-4, and spot weld the intermediate cylinder 5-4 and each mounting side plate 5-2 using a welding torch; Step 5: Place the lifting component 5-11 between lifting unit 1 3-1 and lifting unit 2 3-3. Under the action of the mounting stud 3-2, lifting unit 1 3-1 and lifting unit 2 3-3 clamp the lifting component 5-11, ensuring that the lower end of the lifting component 5-11 is in contact with the top surface of the intermediate cylinder 5-4. Then, use a welding torch to spot weld the intermediate cylinder 5-4 and the lifting component 5-11. Next, install the riser connecting plate 5-6 on the connecting plate positioning plate 4-3, and then use a welding torch to spot weld the two ends of the riser connecting plate 5-6 and the corresponding two supporting risers 5-10. Step 6: Finally, perform full welding on the above-mentioned welding positions. After completing the full welding operation, loosen the locking connection between each bolt and each component in the contact tie frame 5 and the tooling. Then, remove the tie frame 5 to complete the unloading operation.
