Description

Technical Field

[0001] This application relates to the field of fusion device installation, and in particular to a support tooling assembly for a fusion device. Background Technology

[0002] In related technologies, the Dewar base of a fusion device is a key safety component for maintaining the vacuum environment of the main system, and the welding quality of its sealing plate directly affects the safety and reliability of the entire device. The sealing plate is characterized by its large diameter, heavy weight, and high requirements for installation and positioning accuracy. Since the final welding operation must be completed in the extremely confined space and complex environment of the foundation pit, extremely stringent requirements are placed on the support fixture: it must not only bear heavy loads, but also have precise, multi-degree-of-freedom adjustment functions to adapt to positioning in the narrow space and facilitate installation and disassembly.

[0003] Currently, conventional support fixtures are typically bolted to the ground or other structures and adjusted using simple lead screws. These fixtures are simple in structure and suitable for applications with ample hoisting space and low precision requirements. However, they suffer from inherent drawbacks such as limited functionality, low adjustment precision, large space occupation, and poor adaptability, failing to meet the comprehensive requirements of the fusion device's Dewar base sealing plate in complex pit environments. Therefore, improving the adaptability of the fixture components in confined and complex spaces is the technical problem this application aims to solve. Summary of the Invention

[0006] According to the embodiments of this application, the support fixture assembly for a fusion device, by setting a movable component at the bottom of the support body, allows the support body to move with the movable component on the assembly space floor.

The support surface at the top of the support body provides a stable bearing foundation for the sealing plate. Combined with the moving function of the movable component, it can accurately move heavy and large-diameter sealing plates to the area directly opposite the mounting holes of the Dewar base, meeting the requirements for sealing plate installation and positioning, and ensuring high-quality subsequent welding operations. The support fixture assembly does not need to be fixed to the ground or other structures with bolts, simplifying the installation and disassembly process.

[0038] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0039] The following is for reference. Figures 1-9 This application describes a support tooling assembly 200 for a fusion device 100 according to an embodiment of the present application.

[0040] According to an embodiment of this application, a support fixture assembly 200 for a fusion device 100 is provided. The fusion device 100 includes a reaction chamber 10 and a Dewar base 20. The reaction chamber 10 is arranged to form a reaction space 101. A support device is provided in the reaction space 101. The Dewar base 20 is disposed in the reaction space 101 and is mounted on the support device. The bottom of the Dewar base 20 has a mounting hole 201 suitable for a central column to pass through. An assembly space 102 is formed between the bottom of the Dewar base 20 and the reaction chamber 10. The support fixture assembly 200 is disposed in the assembly space 102 and includes a support body 1 and a moving component 2. The top of the support body 1 has a support surface 123 for supporting a sealing plate 202. The moving component 2 is disposed at the bottom of the support body 1 and can move on the ground of the assembly space 102 to move the sealing plate 202 to the area directly opposite the mounting hole 201.

[0041] Understandably, the bearing tooling assembly 200 addresses the narrow and complex assembly space 102 between the bottom of the Dewar base 20 and the reaction chamber 10, where the sealing plate 202 of the Dewar base 20 is assembled. Through the structural design of setting a moving part 2 at the bottom of the bearing body 1, the moving part 2 can directly contact the ground of the assembly space 102 and generate relative movement. The bearing body 1 and the moving part 2 form a fixed connection, thereby driving the bearing body 1 together with the sealing plate 202 supported on its top support surface 123 to move within the assembly space 102. This avoids the conventional tooling method of relying on bolt connections to fix it to the ground or other structures, and solves the problem of conventional fixed tooling occupying a large space and being unable to be flexibly adjusted in a narrow space due to the bolt-fixed structure. This enables the bearing tooling assembly 200 to be flexibly arranged and moved within the narrow assembly space 102.

[0042] The support surface 123 on the top of the supporting body 1 has structural dimensions that are adapted to the bottom contour or structure of the sealing plate 202. It can provide comprehensive and stable support for the large-diameter and heavy sealing plate 202, preventing the sealing plate 202 from tilting, shaking or being damaged during transportation. This provides structural protection for the safe transportation of the sealing plate 202. The moving function of the moving part 2 gives the supporting tooling assembly 200 the ability to adjust its position. The operator can push the supporting body 1 to make the moving part 2 move the sealing plate 202 closer to the mounting hole 201 area of ​​the Dewar base 20 until the sealing plate 202 is moved to the preset position directly opposite the mounting hole 201. This fully meets the stringent requirements for the installation and positioning accuracy of the sealing plate 202 and creates a positioning basis for the subsequent welding operation of the sealing plate 202 in the narrow foundation pit.

[0043] Since the supporting tooling assembly 200 does not need to be fixed to the ground or other structures with bolts, it can be put into use simply by placing it on the ground of the assembly space 102 during installation. During disassembly, it can be removed from the assembly space 102 simply by moving the moving part 2, which greatly simplifies the installation and disassembly process, reduces the difficulty of working in confined spaces, and improves work efficiency. At the same time, the stable support effect and precise positioning function together ensure the positional accuracy and stability of the sealing plate 202 before welding, providing a key guarantee for improving the welding quality of the sealing plate 202. The qualified welding quality of the sealing plate 202 directly determines the sealing performance of the Dewar base 20. As a key safety component for maintaining the vacuum environment of the main system of the fusion device 100, the reliable sealing performance of the Dewar base 20 is directly related to the safety and reliability of the entire fusion device 100. Finally, through the structural design and functional realization of the supporting tooling assembly 200, the comprehensive technical requirements for the assembly of the Dewar base 20 and the sealing plate 202 in complex and confined spaces are met.

[0044] In short, the support fixture assembly 200, by setting a movable component 2 at the bottom of the support body 1, allows the support body 1 to move with the movable component 2 on the ground of the assembly space 102. This adapts to the narrow assembly space 102 between the bottom of the Dewar base 20 and the reaction chamber 10, solving the problems of large space occupation and poor adaptability of conventional fixed fixtures, and enabling flexible transfer of the sealing plate 202 in complex and confined environments. The support surface 123 at the top of the support body 1 provides a stable support foundation for the sealing plate 202. Combined with the moving function of the movable component 2, it can accurately move the heavy, large-diameter sealing plate 202 to the area directly opposite the mounting hole 201 of the Dewar base 20, meeting the installation and positioning requirements of the sealing plate 202 and ensuring high-quality subsequent welding operations. The load-bearing tooling component 200 does not need to be fixed to the ground or other structures with bolts, which simplifies the installation and disassembly process. While improving the convenience of operation in confined spaces, it indirectly ensures the welding quality of the sealing plate 202 through positioning and stable load bearing, thereby enhancing the safety and reliability of the fusion device 100 and meeting the comprehensive technical requirements of the assembly of the Dewar base 20 and the sealing plate 202.

[0045] According to some embodiments of this application, a support tooling assembly 200 for a fusion device 100 has a plurality of positioning portions formed on the top of the support body 1, and a mating portion that mates with the positioning portions is formed on the sealing plate 202.

[0046] Multiple positioning parts on the top of the supporting body 1 cooperate with corresponding mating parts on the sealing plate 202. This mating structure can exert a limiting effect on the sealing plate 202 from multiple directions, restricting the horizontal displacement and rotation tendency of the sealing plate 202 on the support surface 123 of the supporting body 1. Due to the large diameter and heavy weight of the sealing plate 202, it is prone to positional displacement due to external forces or inertia during transportation and positioning. The multi-point limiting structure formed by the multiple positioning parts can stably fit the sealing plate 202 against the support surface 123 of the supporting body 1, ensuring that the sealing plate 202 and the supporting body 1 maintain a relatively fixed positional relationship, avoiding tilting, shaking or displacement of the sealing plate 202, and providing a double structural guarantee for the stable bearing of the sealing plate 202.

[0047] When the moving part 2 moves the supporting body 1 on the ground of the assembly space 102, the sealing plate 202 will not detach from the preset support position due to changes in force during the movement. The operator can control the movement trajectory of the moving part 2 to accurately move the supporting body 1 together with the positioned sealing plate 202 to the area directly opposite the mounting hole 201 of the Dewar base 20. The mating structure of the positioning part and the mating part does not require additional fixing components, which further optimizes the load-bearing stability without increasing the assembly complexity. The design of the moving part 2 without bolt fixing maintains the convenience of installation and disassembly.

[0048] According to some embodiments of this application, a bearing tooling assembly 200 for a fusion device 100 has multiple positioning parts that move relative to the bearing body 1 to adjust the position of the sealing plate 202.

[0049] Understandably, the multiple positioning parts move relative to the supporting body 1, primarily horizontally. This allows each positioning part to adjust its position on the top of the supporting body 1. Through cooperation with the mating parts on the sealing plate 202, a positional correction force is applied to the sealing plate 202. When the sealing plate 202 is placed on the support surface 123 of the supporting body 1, there may be an initial positional deviation. The movable nature of the multiple positioning parts allows for targeted adjustment of the horizontal displacement deviation of the sealing plate 202. The position of the sealing plate 202 can be corrected without moving the entire supporting body 1, effectively solving the problem of the difficulty in significantly adjusting the supporting body 1 within the confined assembly space 102. After the moving component 2 moves the supporting body 1 to the approximate area corresponding to the mounting hole 201, the horizontal fine-tuning of the positioning parts can further reduce the positional error, ensuring that the sealing plate 202 is precisely aligned with the mounting hole 201 of the Dewar base 20, fully meeting the requirements for the installation positioning accuracy of the sealing plate 202.

[0050] The horizontal movement function of the positioning unit provides higher precision positioning for the sealing plate 202, ensuring that its positional accuracy before welding meets the technical standards for welding operations. This guarantees the alignment accuracy between the sealing plate 202 and the surrounding structure of the Dewar base 20 mounting hole 201 during welding, avoiding problems such as misalignment and uneven gaps in the weld joint caused by positioning deviations, and directly ensuring the welding quality of the sealing plate 202. The method of fine-tuning the position of the sealing plate 202 without significantly moving the supporting body 1 reduces the workload in confined spaces and improves assembly efficiency.

[0051] According to some embodiments of this application, the support tooling assembly 200 for a fusion device 100 further includes: a support member 3, which is detachably or deformably disposed at the bottom of the support body 1, and is adapted to contact the ground of the assembly space 102 after the support body 1 is moved into place to support the support body 1.

[0052] The support component 3 is detachably or deformably mounted on the bottom of the supporting body 1. This allows the supporting body 1 to move by removing or deforming the support component 3, preventing interference between the support component 3 and the floor of the assembly space 102. This ensures that the moving component 2 can smoothly move the supporting body 1 and the top-mounted sealing plate 202 within the confined assembly space 102, without affecting the transfer and initial positioning process of the sealing plate 202. After the supporting body 1 moves the sealing plate 202 to a precise position aligned with the mounting hole 201 through the coordinated action of the moving component 2 and the positioning part, the support component 3 can form stable contact with the floor of the assembly space 102 by fixing it in place or restoring its deformation. The supporting reaction force from the floor supports the supporting body 1, effectively dispersing the weight load transmitted from the sealing plate 202 to the supporting body 1, ensuring the positional stability of the supporting body 1 and the sealing plate 202 after positioning, and further consolidating the positioning effect achieved by the positioning part and the moving component 2 in the early stages.

[0053] Understandably, the moving component 2 is responsible for adjusting and transporting the position of the main body 1, while the supporting component 3 is responsible for providing stable support after positioning. This collaboratively resolves the contradiction between the flexibility of transporting the sealing plate 202 and the stability of its positioning within a confined space. The stable support ensures that the sealing plate 202 maintains a precise position aligned with the mounting hole 201 of the Dewar base 20 throughout the welding process, avoiding issues such as weld joint misalignment and uneven gaps caused by the displacement of the sealing plate 202. This directly provides structural assurance for the welding quality of the sealing plate 202, improving the reliability of the welding quality. Simultaneously, the detachable design of the supporting component 3 simplifies the installation and disassembly process, and its deformable nature adapts to variations in the flatness of the assembly space 102 floor, achieving stable support without additional adjustments to the floor structure. Neither component occupies additional space in the confined assembly space 102, fully adapting to the complex and confined working environment between the bottom of the Dewar base 20 and the reaction chamber 10.

[0054] According to some embodiments of this application, the support tooling assembly 200 for a fusion device 100 further includes: a lifting component 4, which is disposed at the bottom of the support body 1 and is adapted to lift the support body 1 to adjust the height of the sealing plate 202.

[0055] The lifting component 4 is located at the bottom of the supporting body 1. The lifting action of the lifting component 4 can directly act on the supporting body 1, causing the supporting body 1 to shift vertically, thereby driving the sealing plate 202 supported on the top support surface 123 of the supporting body 1 to adjust its height synchronously. Since the installation of the sealing plate 202 not only requires precise horizontal alignment with the mounting holes 201 of the Dewar base 20, but also requires precise vertical alignment with the welding surfaces around the mounting holes 201, and the sealing plate 202 itself is heavy and has a large diameter, it is difficult to achieve fine-tuning of its height in the narrow assembly space 102 through other means. The lifting component 4, by acting directly on the supporting body 1, can control the height of the sealing plate 202, effectively correcting the vertical positional deviation of the sealing plate 202, so that the sealing plate 202 meets the installation positioning accuracy requirements in both horizontal and vertical dimensions. Meanwhile, the lifting component 4 is integrated into the bottom of the supporting body 1, without requiring additional assembly space 102. It is suitable for the narrow and complex working environment between the bottom of the Dewar base 20 and the reaction chamber 10, and does not affect the movement function of the moving component 2 or the supporting function of the supporting component 3.

[0056] In some embodiments of this application, the lifting component 4 is constructed as a jack, and multiple jacks are used to lift the supporting body 1.

[0057] According to some embodiments of this application, a support tooling assembly 200 for a fusion device 100 has a support member 3 and a moving member 2 alternatively disposed on a support body 1.

[0058] It should be noted that the support component 3 and the moving component 2 are interchangeably mounted on the supporting body 1. Combined with the lifting function of the lifting component 4, after the lifting component 4 lifts the supporting body 1 and the top-mounted sealing plate 202, the moving component 2 at the bottom of the supporting body 1 is removed from the assembly space 102 and no longer bears the load. At this time, the replacement operation of the support component 3 and the moving component 2 can be carried out smoothly, avoiding the interference of the weight of the sealing plate 202 on the replacement process, and making the replacement process operable in the narrow assembly space 102. This replacement design allows the moving component 2 and the support component 3 to not occupy the bottom space of the supporting body 1 at the same time, effectively controlling the structural volume of the supporting body 1, avoiding the problem of excessive space occupation caused by the coexistence of multiple components, adapting to the narrow and complex assembly environment between the bottom of the Dewar base 20 and the reaction chamber 10, while ensuring the structural compactness of the supporting body 1 and not affecting the functional realization of other components.

[0059] Before replacement, the movable component 2 functions as a transporter, moving the main support 1 and the sealing plate 202 flexibly within the assembly space 102 to achieve initial horizontal positioning of the sealing plate 202. After replacement, the supporting component 3 forms stable contact with the floor of the assembly space 102, providing load-bearing support, distributing the weight load transmitted by the sealing plate 202, and preventing the main support 1 from settling, shifting, or tilting during subsequent processes such as welding, thus ensuring the positional stability of the sealing plate 202 after positioning. This component replacement achieves synergy between the flexible transport of the movable component 2 and the stable load-bearing of the supporting component 3, solving both the flexibility requirement for transporting the sealing plate 202 in a confined space and the reliability requirement for stable support after positioning.

[0060] According to some embodiments of this application, the support tooling assembly 200 for a fusion device 100 further includes: an adjustment shim 5, which is disposed between the support member 3 and the ground or between the top of the support member 3 and the support body 1.

[0061] The adjusting shim 5 can be flexibly positioned between the supporting component 3 and the floor of the assembly space 102, or between the top of the supporting component 3 and the load-bearing body 1, after the lifting component 4 lifts the load-bearing body 1. The lifting action of the lifting component 4 causes the load-bearing body 1 to detach from its initial support state, forming an operable gap at the corresponding installation position. This ensures that the adjusting shim 5 can be placed smoothly without interfering with the established positional relationships of other components such as the moving component 2 and the positioning part, ensuring that the initial positioning results are not affected. During the process of adjusting the sealing plate 202 of the Dewar base 20 to its final position, the on-site measurement data can reflect the deviation between the current position of the sealing plate 202 and the preset installation position. These deviations may originate from factors such as unevenness of the floor of the assembly space 102, minor dimensional errors of the supporting component 3 or the load-bearing body 1, etc. By adjusting the thickness of the shim 5 according to the on-site measurement data, the thickness of the adjusting shim 5 can be matched with the deviation, achieving precise compensation for the deviation. Once the adjusting shim 5 is installed in place, it can fill the gap between the supporting component 3 and the ground or between the supporting component 3 and the bearing body 1. Through thickness compensation, it corrects the height and level of the bearing body 1, making the supporting force distribution of the supporting component 3 on the bearing body 1 more uniform. This prevents the bearing body 1 from tilting or settling due to gaps or dimensional deviations, thereby ensuring that the levelness and height accuracy of the sealing plate 202 in the final position meet the requirements. It also ensures that the welding surface of the sealing plate 202 and the periphery of the mounting hole 201 of the Dewar base 20 are in close contact in the final position. This eliminates the hidden dangers such as uneven gaps and misalignment of the welding joints caused by minor positional deviations, providing a core guarantee for the high-quality development of the welding operation of the sealing plate 202, and significantly improving the safety and reliability of the fusion device 100.

[0062] According to some embodiments of this application, the support tooling assembly 200 for a fusion device 100 further includes: a displacement sensor 41, which is disposed on the lifting component 4 and is used to detect the lifting height of the support body 1.

[0063] The displacement sensor 41 is installed on the lifting component 4 and can capture the actual lifting height data of the supporting body 1 in real time. The core function of the lifting component 4 is to adjust the height of the supporting body 1 to match the height matching requirements of the sealing plate 202 and the welding surface around the mounting hole 201 of the Dewar base 20. The detection function of the displacement sensor 41 allows the operator to grasp the lifting range of the supporting body 1 in real time, without relying on experience judgment or additional measuring tools. The operator can accurately control the movement stroke of the lifting component 4 based on the detection data, effectively avoiding the problem of hard collision between the sealing plate 202 and the Dewar base 20 due to excessive lifting, or gap between the sealing plate 202 and the welding surface due to insufficient lifting. This enables fine adjustment of the height of the sealing plate 202, and the positioning error of the sealing plate 202 in the height direction is strictly controlled within the design allowable range, ensuring that the sealing plate 202 meets the installation positioning requirements in terms of height.

[0064] The height-oriented positioning ensures a perfect fit between the sealing plate 202 and the welding surfaces around the mounting holes 201 of the Dewar base 20, eliminating potential problems such as uneven weld joint gaps and misalignment caused by height deviations. This lays a crucial foundation for high-quality welding of the sealing plate 202. Meanwhile, the real-time detection function of the displacement sensor 41 reduces the repeated trial and error process during height adjustment, eliminating the need for operators to frequently interrupt operations for additional measurements. This improves work efficiency in confined spaces while reducing operational complexity.

[0065] According to some embodiments of this application, a support fixture assembly 200 for a fusion device 100 includes a support body 1 comprising a bottom frame 11, a top frame 12, longitudinal beams 13, and support beams 14. The bottom frame 11 and the top frame 12 are spaced apart in the height direction. The longitudinal beams 13 are disposed between the bottom frame 11 and the top frame 12, and the longitudinal beams 13 are configured to be multiple and spaced apart from each other. The support beams 14 are connected between the top frame 12 and the bottom frame 11, connected between the longitudinal beams 13 and the support of the top frame 12, or connected between the longitudinal beams 13 and the top frame 12. The support beams 14 extend obliquely relative to the longitudinal beams 13.

[0066] Understandably, the load-bearing body 1 is spaced apart in the vertical direction by a bottom frame 11 and a top frame 12. Multiple longitudinal beams 13, arranged at intervals, connect the bottom frame 11 and the top frame 12, forming a vertical force transmission path. This allows the weight of the sealing plate 202 carried by the top frame 12 to be evenly distributed to the bottom frame 11 through the longitudinal beams 13, avoiding structural deformation caused by local stress concentration. The support beam 14 adopts a multi-position connection design, connecting both the top frame 12 and the bottom frame 11, and the longitudinal beam 13 and the top frame 12. It also extends at an incline relative to the longitudinal beam 13, so that the support beam 14, together with the longitudinal beam 13, the bottom frame 11, or the top frame 12, forms a triangular stable structure. This structure can effectively resist horizontal forces and lateral forces generated by vertical loads, significantly improving the overall stiffness and structural stability of the load-bearing body 1. This prevents the load-bearing body 1 from bending, twisting, or tilting when carrying a heavy, large-diameter sealing plate 202, providing a stable load-bearing foundation for the sealing plate 202.

[0067] The stable and rigid load-bearing body 1 structure ensures that the sealing plate 202 maintains the preset posture during transportation, avoiding tilting, shaking or positional deviation of the sealing plate 202 due to structural deformation, ensuring the positional accuracy of the moving part 2 when it drives the load-bearing body 1 for transportation, and providing a stable structural benchmark for the horizontal fine adjustment of the positioning part and the height adjustment of the lifting part 4. Through the layout of the longitudinal beam 13 and the support beam 14, the overall volume of the load-bearing body 1 is controlled while meeting the load-bearing requirements, avoiding structural redundancy that occupies too much assembly space 102.

[0068] In some embodiments of this application, the bottom frame 11 and the top frame 12 are made of channel steel, the support beam 14 is made of angle steel, and the longitudinal beam 13 is made of steel pipe. The connection between the bottom frame 11, the top frame 12, the support beam 14, and the longitudinal beam 13 is bolted, which facilitates further disassembly and transportation. After the operation is completed, the load-bearing body 1 can be disassembled into multiple independent parts. Each part is smaller and lighter, making it easier for operators to move and remove it flexibly, avoiding the problem that the overall structure cannot be smoothly removed from the work area due to its large size. During transportation, the disassembled parts can be transported separately, which greatly reduces the space occupation and handling difficulty during transportation and improves the convenience of transporting the tooling components between different work scenarios. At the same time, the detachable feature allows each part to be disassembled and replaced individually when wear, fatigue, or partial damage occurs, without the need to scrap the entire tooling component, thus extending the overall service life of the tooling and reducing long-term use costs.

[0069] According to some embodiments of this application, a support tooling assembly 200 for a fusion device 100 has crossbeams 121 extending intersecting each other within a top frame 12, and a support plate 122 is formed on the top frame 12 and / or the crossbeams 121, the support plate 122 being used to support the sealing plate 202.

[0070] The top frame 12 is equipped with intersecting beams 121. This intersecting structure creates a multi-directional force transmission path within the top frame 12, effectively dispersing the load applied to the top frame 12 by the sealing plate 202. Simultaneously, it significantly enhances the overall bending stiffness and torsional resistance of the top frame 12, preventing localized dents or overall deformation due to the large diameter and heavy weight of the sealing plate 202. This provides a stable upper structural foundation for supporting the sealing plate 202. Support plates 122 are installed on the top frame 12 and / or beams 121, forming support surfaces 123 that directly contact the bottom of the sealing plate 202. The distribution of the support plates 122 expands the contact area between the sealing plate 202 and the load-bearing body 1, allowing the weight of the sealing plate 202 to be evenly distributed to the top frame 12, beams 121, subsequent longitudinal beams 13, and bottom frame 11. This prevents the sealing plate 202 from undergoing excessive localized stress, resulting in compression deformation or surface damage.

[0071] It should be noted that the mating part at the bottom of the sealing plate 202 is a limiting block. The limiting block cooperates with the support plate 122 and is used to limit the sealing plate 202 during temporary placement and transportation to ensure the stability of the sealing plate 202. At the same time, it is used to adjust the horizontal position of the sealing plate 202 of the Dewar base 20 by moving the support plate 122.

[0072] In some embodiments of this application, multiple support plates 122 move relative to the bearing body 1. The horizontal position of the support plates 122 can be adjusted by adjusting bolts, and the horizontal position of the sealing plate 202 can be adjusted by the limiting block of the sealing plate 202 of the Dewar base 20.
