Description

Technical Field

[0001] The invention relates to the technical field of bus duct assembly, and in particular to a tooling platform and a method for improving the assembly accuracy of elbow bus ducts. Background Art

[0002] Elbow bus duct is a common distribution device for power transmission, which is used in various power systems, especially in situations where the power line layout is complex and multiple corner connections are required. As an important part of power transmission, the assembly of elbow bus duct requires extremely high precision to ensure the reliability of electrical connections, transmission efficiency and the overall safety of system operation. However, in the actual production and assembly process, the assembly tooling platform of the existing technology has many shortcomings and it is difficult to meet the high-precision and high-efficiency assembly requirements.

[0003] In the existing assembly technology, the positioning structure design of the tooling platform is relatively simple, and lacks a complete precision adjustment mechanism. During the assembly process, the overall assembly accuracy is often affected by the deviation of the position and spacing of the components. For example, the Chinese patent announcement CN212494958U discloses a vertical elbow bus duct riveting tool that is easy to seal. The bottom cover is limited by a baffle, and the staff gradually manually installs the busbar connecting plate and the top cover to complete the assembly. Although this method can realize the assembly of the elbow bus duct, it still has the following technical defects: 1. Insufficient positioning accuracy: The tooling only relies on the baffle for limiting and correction, and the positioning structure is single. It cannot ensure the precise position of the components during the assembly process, resulting in large deviations in the assembly of parts. Especially in the assembly of complex corners of the bus duct, it is difficult for the limiting mechanism to effectively cover all key parts, and it is very easy to have spacing or position deviations. 2. Uncontrollable assembly errors: Due to the lack of high-precision adjustment devices, the spacing between parts cannot be fine-tuned according to actual needs during the assembly process. Especially in the riveting operation, due to the accumulation of assembly errors, the riveting position of the finished bus duct often has obvious deviations, which ultimately leads to the assembly result not meeting the design requirements, and it is difficult to correct it through subsequent processes after the riveting is completed. 3. Low degree of automation: Most of the current assembly tools are manually operated, relying on staff to gradually assemble and fix each part. This method is not only inefficient, but also prone to problems such as inaccurate positioning and insufficient tightening due to human factors, affecting the assembly quality.

[0004] Furthermore, the tooling can only be designed for elbow bus ducts of specific shapes, lacks flexibility and versatility, and cannot adapt to the assembly requirements of bus ducts of various specifications and shapes. Summary of the invention

[0005] In view of the above problems, a tooling platform for improving the assembly accuracy of elbow bus duct is provided. By proposing an efficient assembly tooling that can not only realize automatic correction and precise positioning of the elbow bus duct assembly parts but also accurately control the installation displacement and spacing, the problems of insufficient positioning accuracy and uncontrollable assembly error of the existing assembly tooling are solved. At the same time, it can adapt to the assembly needs of elbow bus ducts of different shapes and specifications, not only meet the assembly of a single type of bus duct, but also have strong versatility and flexibility, effectively improve the assembly quality and production efficiency, and comprehensively optimize the assembly process of the elbow bus duct.

[0015] A method for using a tooling platform for improving the assembly accuracy of an elbow bus duct is applied to a tooling platform for improving the assembly accuracy of an elbow bus duct, and includes the following steps:

[0016] S1: First, according to the shape characteristics of the elbow bus duct, the two groups of top support modules are adjusted to the support angle that adapts to the shape through the adjustment module, for example, the angle is adjusted to a right angle to meet the positioning requirements of the standard lower Z-shaped main board; then, the lower Z-shaped main board is placed between the two adjusted groups of top support modules, so that the lower Z-shaped main board is automatically centered and stably fixed between the two groups of top support modules under the action of its own weight; the mechanical support characteristics of the two groups of top support modules are used to achieve preliminary correction of the lower Z-shaped main board; after confirming the horizontality and center position of the lower Z-shaped main board, the first bidirectional synchronous limiting unit is driven to move, and the side wall of the lower Z-shaped main board is internally supported and fixed through the synchronous movement of the first limiting part and the second limiting part, so as to ensure the stability and support strength of the lower Z-shaped main board;

[0017] S2: Subsequently, the operator takes the upper Z-shaped main board, places it horizontally between the two groups of correction limit modules, and ensures that the bending corners of the upper Z-shaped main board are in contact with the correction ends of the two groups of correction limit modules respectively; and corrects and locks the upper Z-shaped main board through the third limit part and the fourth limit part provided in the two groups of correction limit modules respectively; when the two groups of upper Z-shaped main boards are fixed, the two groups of correction limit modules are synchronously driven to move, so that they drive the upper Z-shaped main board longitudinally close to the lower Z-shaped main board at a preset speed; when the preset stroke position is reached, the two groups of correction limit modules automatically stop moving, ensuring that an appropriate installation gap is reserved between the upper Z-shaped main board and the lower Z-shaped main board; the operator then takes the copper busbar and two groups of limit blocks, and fixes the copper busbar between the upper Z-shaped main board and the lower Z-shaped main board in turn, ensuring that the copper busbar is accurately positioned and the limit blocks are firmly installed, thereby completing the copper busbar installation steps;

[0018] S3: After completing the installation of the limit block and the copper busbar, the operator takes two sets of Z-shaped side panels in turn and places them on both sides of the upper Z-shaped main board and the lower Z-shaped main board respectively; and drives the limit plate to move, and through the pushing action of the limit plate, gradually pushes the two sets of Z-shaped side panels along the preset trajectory to the correct assembly position, ensuring that the two sets of Z-shaped side panels are completely flush with the side walls of the upper Z-shaped main board and the lower Z-shaped main board and fit tightly; under the action of the limit plate, the Z-shaped side panels can achieve high-precision positioning and stable fixation;

[0019] S4: After the installation of the two sets of Z-shaped side panels is completed, in order to further tighten the connection between the upper Z-shaped main board and the lower Z-shaped main board and the Z-shaped side panels, and to facilitate the final riveting operation, the operator needs to connect an external power supply to drive the third electric push rod to move; through the output force of the third electric push rod, the sliding frame and the supporting plate fixed thereon are synchronously driven to slide along the preset track of the tooling platform; during the movement, the supporting plate longitudinally supports the lower Z-shaped main board, and gradually drives the lower Z-shaped main board upward to approach the upper Z-shaped main board; during the supporting process, the tightness of the connection structure can be effectively guaranteed through the stable control of the sliding frame and the precise load of the supporting plate;

[0020] S5: After the support plate completes the longitudinal support of the lower Z-shaped main board, the operator needs to reconfirm the connection status of the upper Z-shaped main board, the lower Z-shaped main board and the two sets of Z-shaped side panels to ensure that they have reached a stable state; finally, start the riveting equipment and perform the final riveting of the upper Z-shaped main board, the lower Z-shaped main board and the two sets of Z-shaped side panels according to the riveting process preset on the tooling platform.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention adopts a modular adjustment design, which can flexibly adjust the support angle and the limit structure according to the different shapes of the elbow bus duct. Through the coordinated cooperation of the top support module and the correction limit module, the upper Z-shaped main board, the lower Z-shaped main board and the Z-shaped side board of the elbow bus duct are accurately corrected and assembled, ensuring the accurate alignment and stable connection of each plate during the assembly process, and significantly reducing the error caused by human operation;

[0023] 2. The present invention uses a second bidirectional synchronous limiting unit to internally support and fix the upper Z-shaped main board, and combines the longitudinal supporting function of the sliding frame and the supporting plate to form a stable limiting support during the assembly of the elbow bus duct, avoiding assembly errors caused by component offset or loosening, and ensuring the structural stability after assembly.

DETAILED DESCRIPTION

[0035] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] See also Figures 1 to 10 As shown: A tooling platform for improving the assembly accuracy of the elbow bus duct, used for limiting the support of the elbow bus duct 5, comprising: a base frame 1; an adjustment module 2, the adjustment module 2 is fixedly arranged on the base frame 1 in a horizontal state, and the adjustment module 2 is provided with two first adjustment plates 31 and second adjustment plates 32 that can be tilted and adjusted; a top support module 3, the top support module 3 is symmetrically arranged with two groups and respectively vertically arranged on the first adjustment plate 31 and the second adjustment plate 32; and the two groups of the top support modules 3 can respectively move along the first adjustment plate 31 and the second adjustment plate 32. The section plate 31 and the second adjustment plate 32 slide in the long side direction; the two groups of the supporting modules 3 are respectively used to limit and support the two sides of the elbow bus duct 5; the correction limit module 4, the correction limit module 4 is provided with two groups, the two groups of the correction limit modules 4 are vertically arranged on the base frame 1 and are located on one side of the adjustment module 2; the correction ends of the two groups of the correction limit modules 4 are vertically arranged toward the elbow bus duct 5; the two groups of the correction limit modules 4 are used to limit and support the bending corners of the elbow bus duct 5.

[0037] The elbow bus duct 5 is composed of two groups of relatively arranged upper Z-shaped main boards 51 and lower Z-shaped main boards 52, two Z-shaped side boards 53 for sealing the two sides of the upper Z-shaped main boards 51 and the lower Z-shaped main boards 52, and limit blocks 55 that can limit and fix the copper busbar 54 in the upper Z-shaped main boards 51 and the lower Z-shaped main boards 52; two limit blocks 55 are provided, and the two limit blocks 55 are detachably arranged at the two ends of the upper Z-shaped main boards 51 and the lower Z-shaped main boards 52 respectively; wherein the outer walls on both sides of the long sides of the upper Z-shaped main boards 51 and the lower Z-shaped main boards 52 are also vertically provided with side strips 56.

[0038] When the elbow bus duct 5 needs to be assembled, the staff firstly adjusts the first adjustment plate 31 and the second adjustment plate 32 to be tilted, and adjusts the angle between the first adjustment plate 31 and the second adjustment plate 32 to be set at a right angle. Then the two groups of the top support modules 3 are driven to act respectively, so that the two groups of the top support modules 3 are adjusted according to the size of the current elbow bus duct 5 and the required support position, and the two groups of the top support modules 3 are adjusted respectively. After the two groups of the top support modules 3 are adjusted. The staff takes the lower Z-shaped main board 52 and places the lower Z-shaped main board 52 in the support interval formed between the two groups of the top support modules 3. Since the two groups of the top support modules 3 are tilted at this time, when the lower Z-shaped main board 52 is placed between the two groups of the top support modules 3, the bend of the lower Z-shaped main board 52 will automatically slide downward under the action of gravity, and finally the bend is in the center position between the two groups of the top support modules 3, ensuring the accurate positioning of the main board.

[0039] At this time, the staff member drives the two sets of top support modules 3 to move again, and implements precise limiting, so as to ensure that the lower Z-shaped main board 52 is firmly fixed in the support interval. Next, the staff member takes the upper Z-shaped main board 51 and places it between the two sets of correction limit modules 4. Through the action of the two sets of correction limit modules 4, the upper Z-shaped main board 51 is limited, and it is located directly above the lower Z-shaped main board 52. After the upper Z-shaped main board 51 is accurately fixed by the two sets of correction limit modules 4, the staff member drives the two sets of correction limit modules 4 to move synchronously, so that the two sets of correction limit modules 4 drive the upper Z-shaped main board 51 to approach the lower Z-shaped main board 52 according to the preset installation spacing, thereby accurately controlling the installation spacing between the upper Z-shaped main board 51 and the lower Z-shaped main board 52.

[0040] Finally, the staff fixes the copper bar 54 between the upper Z-shaped main board 51 and the lower Z-shaped main board 52 through two sets of limit blocks 55. After this process, the staff installs the two Z-shaped side panels 53 on both sides of the upper Z-shaped main board 51 and the lower Z-shaped main board 52, and rivets them firmly using a riveting machine. At this point, the assembly of the elbow bus duct 5 is completed. By using precise mechanical positioning, the installation spacing and position of each component can be strictly controlled, thereby ensuring high precision and high efficiency in the assembly process of the elbow bus duct 5.

[0041] The synergistic effect of the top support module 3 and the correction limit module 4 can realize automatic adjustment of the assembly status of each component, reduce manual intervention, avoid errors in traditional assembly methods, ensure that each component is firmly fixed, reduce the difficulty of later adjustment, and improve production quality and reliability.

[0042] See also Figure 1 and Figure 2 As shown: the adjustment module 2 also includes a fixed plate 21 and a first linear drive 22 and a second linear drive 23 that can respectively drive the first adjustment plate 31 and the second adjustment plate 32 to perform flipping adjustment; the fixed plate 21 is horizontally fixed on the base frame 1; the first adjustment plate 31 and the second adjustment plate 32 are respectively hinged at both ends of the fixed plate 21; the first linear drive 22 and the second linear drive 23 are both symmetrically arranged under the base frame 1 in a vertical state, and the output shafts of the first linear drive 22 and the second linear drive 23 are respectively arranged through the base frame 1 toward the first adjustment plate 31 and the second adjustment plate 32; and the output shafts of the first linear drive 22 and the second linear drive 23 are respectively hinged to the third hinge part 24 vertically arranged on the outer wall of the first adjustment plate 31 and the second adjustment plate 32.

[0043] The first linear drive 22 and the second linear drive 23 are specifically first electric push rods.

[0044] When the support angle of the first adjustment plate 31 needs to be adjusted, an external power source is first connected to drive the first linear driver 22. The first linear driver 22 directly drives the first adjustment plate 31 to move along a preset adjustment track through the extension of its output shaft, thereby adjusting the support angle of the first adjustment plate 31. The angle adjustment method of the second adjustment plate 32 is consistent with that of the first adjustment plate 31, and synchronous adjustment is achieved through the corresponding linear driver action.

[0045] See also Figure 3 , Figure 4 and Figure 6As shown: the supporting module 3 includes a guiding unit 33, an angle adjustment unit 34, a first linear driving unit 35 and a first bidirectional synchronous limiting unit 36; the following takes the supporting module 3 being arranged on the first adjustment plate 31 as an example, the angle adjustment unit 34 is vertically arranged on the first adjustment plate 31 through the guiding unit 33; and the angle adjustment unit 34 can slide along the long side direction of the first adjustment plate 31 through the guiding unit 33; the guiding unit 33 is arranged on the base frame 1 in parallel along the long side direction of the first adjustment plate 31; the first linear driving unit 35 is fixedly arranged at the adjustment end of the angle adjustment unit 34; the first bidirectional synchronous limiting unit 36 ​​is horizontally fixedly arranged at the driving end of the first linear driving unit 35, and the first bidirectional synchronous limiting unit 36 ​​is used for transverse bidirectional limiting of the elbow bus duct 5.

[0046] When the lower Z-shaped main board 52 needs to be corrected and supported, the staff first operates the guide unit 33 to drive the angle adjustment unit 34 to slide along the set trajectory to the target support position, and simultaneously adjusts the positions of the first linear drive unit 35 and the first bidirectional synchronous limiting unit 36. After the angle adjustment unit 34 slides to the target support point, it is immediately locked to ensure that the angle adjustment unit 34 is firmly fixed at the current support point. Subsequently, the first linear drive unit 35 is started to drive its output shaft to extend axially, and at the same time, the first bidirectional synchronous limiting unit 36 ​​is driven to move toward the lower Z-shaped main board 52 until it moves to the preset support position and stops. At this time, the limiting end of the first bidirectional synchronous limiting unit 36 ​​remains in a retracted state (that is, the side walls of the first limiting portion 362 and the second limiting portion 363 are in a non-contact state with the side strip 56 of the lower Z-shaped main board 52 and are both arranged close to the second slide rail 361), reserving adjustment space for subsequent operations.

[0047] After the lower Z-shaped main board 52 is accurately placed between the two groups of top support modules 3, due to the effect of gravity, its corner portion automatically moves to the center within the support range of the top support module 3. To further ensure the stability of the lower Z-shaped main board 52, the staff only needs to drive the first bidirectional synchronous limiting unit 36 ​​to slide its limiting end (i.e., the first limiting portion 362 and the second limiting portion 363) from the center of the second slide rail 361 toward the two ends of the second slide rail 361, respectively, until the first limiting portion 362 and the second limiting portion 363 respectively abut against the side strips 56 on both sides of the lower Z-shaped main board 52, so as to realize the active internal support and limiting of the lower Z-shaped main board 52, thereby effectively preventing the lower Z-shaped main board 52 from positional displacement or autonomous sliding in subsequent assembly operations, and ensuring the stability and accuracy of the entire assembly process.

[0048] Through the coordinated action of the guide unit 33, the angle adjustment unit 34 and the first bidirectional synchronous fixing unit 36, the automatic correction and multi-level fixing of the lower Z-shaped main board 52 are realized, which effectively solves the assembly error problem caused by loose fixing or position offset in the traditional assembly process, and greatly improves the assembly accuracy and operation efficiency.

[0049] The guide unit 33 includes a first slide rail 331, a first slider 332 and a locking knob 333; the first slide rail 331 is provided with two groups, and the two groups of the first slide rails 331 are symmetrically arranged on the first adjustment plate 31 along the long side direction of the first adjustment plate 31; the first slider 332 is arranged across the two groups of the first slide rails 331, and the angle adjustment unit 34 is fixedly arranged on the first slider 332; the locking knob 333 is screwed and arranged in the middle part of the first slider 332, and the locking end of the locking knob 333 passes through the first slider 332 and abuts against the first adjustment plate 31.

[0050] When it is necessary to adjust the support position of the angle adjustment unit 34, the first linear drive unit 35 and the first bidirectional synchronous limiting unit 36, the staff first loosens the locking knob 333 to release the limit between the first slider 332 and the first adjustment plate 31, so that the angle adjustment unit 34 can slide freely to the desired position. In this process, the staff can adjust the support position of the angle adjustment unit 34 according to actual needs, and accurately position the angle adjustment unit 34 to the target support point by manual pushing. After the angle adjustment unit 34 reaches the desired support position, the staff tightens the locking knob 333 to re-limit the first slider 332 and the first adjustment plate 31, ensuring that the angle adjustment unit 34 remains stable at the new support position to prevent it from accidentally moving or loosening, thereby ensuring the position accuracy during the entire assembly process.

[0051] See also Fig.10 As shown: the angle adjustment unit 34 is composed of a first hinge part 341, a second hinge part 342 and a pin shaft 344 capable of locking the first hinge part 341 and the second hinge part 342; the first hinge part 341 and the second hinge part 342 are also respectively penetrated with a pin hole 343 for the pin shaft 344 to pass through, and the pin holes 343 are respectively arranged in a plurality of groups along the circumferential direction of the axis of the first hinge part 341 and the second hinge part 342; the connecting end of the first hinge part 341 is fixedly connected to the guiding unit 33; the connecting end of the second hinge part 342 is fixedly connected to the connecting end of the first linear drive unit 35.

[0052] When it is necessary to adjust the support angle of the first linear drive unit 35, the staff first unplugs the pin 344 inserted in the first hinge 341 and the second hinge 342 to release the fixed connection between the first hinge 341 and the second hinge 342, so that the first hinge 341 and the second hinge 342 can move freely. Then, the staff holds the first linear drive unit 35 and adjusts the position and angle of the first linear drive unit 35 according to actual needs and the preset support angle to ensure that it reaches the required precise angle. After the adjustment is completed, the staff reinserts the pin 344 into the coaxial pin hole 343 of the first hinge 341 and the second hinge 342 to ensure that the pin 344 is tightly fixed and restores the connection between the first hinge 341 and the second hinge 342, thereby ensuring that the first linear drive unit 35 operates stably at the new angle.

[0053] The first linear drive unit 35 is composed of an adjustment frame fixedly connected to the connecting end of the second hinged portion 342, a second electric push rod fixedly arranged in the adjustment frame, and a telescopic frame fixedly arranged on the output shaft of the second electric push rod; a guide rod is also vertically fixedly arranged on one side of the telescopic frame, and the rod portion of the guide rod passes through the adjustment frame and slidably cooperates with the adjustment frame.

[0054] See also Fig.10 As shown: the first bidirectional synchronous limiting unit 36 ​​includes a second slide rail 361, a first limiting portion 362, a second limiting portion 363 and a synchronous driver 364; the second slide rail 361 is vertically fixedly arranged on the driving end of the first linear drive unit 35; the first limiting portion 362 and the second limiting portion 363 are both slidably arranged on the second slide rail 361, and the first limiting portion 362 and the second limiting portion 363 are respectively arranged near the two ends of the second slide rail 361; the synchronous driver 364 is fixedly arranged on one side of the second slide rail 361 in parallel along the long side direction of the second slide rail 361; the synchronous driver 364 is used to synchronously drive the first limiting portion 362 and the second limiting portion 363 to slide toward each other.

[0055] The second limiting portion 363 and the first limiting portion 362 are symmetrically arranged.

[0056] The synchronous driver 364 is composed of a bidirectional screw and a servo motor for driving the bidirectional screw to rotate; the first limit portion 362 and the second limit portion 363 are symmetrically arranged at both ends of the bidirectional screw and are respectively connected to the first limit portion 362 and the second limit portion 363 in transmission connection.

[0057] When the lower Z-shaped main board 52 is supported by two groups of supporting modules 3 , the side walls of the lower Z-shaped main board 52 are supported by the top surfaces of the first limiting portion 362 and the second limiting portion 363 .

[0058] After the lower Z-shaped main board 52 is supported and corrected by two groups of supporting modules 3, if it is necessary to further limit and fix the lower Z-shaped main board 52 to ensure that it always maintains a stable and fixed position during the subsequent assembly process, at this time, the staff only needs to connect an external power supply to drive the synchronous driver 364 to operate. Through the action of the synchronous driver 364, the first limiting portion 362 and the second limiting portion 363 move away from each other and move synchronously, so that the outer sides of the first limiting portion 362 and the second limiting portion 363 are used to internally support the side strips 56 on both sides of the lower Z-shaped main board 52, thereby ensuring that the lower Z-shaped main board 52 will not be displaced or deformed during the support process. With the completion of the internal support action, the stability of the lower Z-shaped main board 52 is significantly improved, further ensuring that it is always in a state of precise positioning during the entire assembly process, avoiding errors and inaccuracies in subsequent assembly due to instability or offset.

[0059] See also Figure 4 and Figure 7 As shown: the first bidirectional synchronous limiting unit 36 ​​also includes a limiting plate 37 that can slide along the guiding direction of the second slide rail 361, and the limiting plates 37 are provided in two groups, and the two groups of limiting plates 37 are respectively slidably arranged at both ends of the second slide rail 361 in a vertical state.

[0060] The limit block 55 is also threadedly provided with a locking knob capable of fixing the limit plate 37 at the adjustment position.

[0061] When assembling the Z-shaped side panels 53, in order to ensure that the two groups of the Z-shaped side panels 53 can be set flush with the side walls of the upper Z-shaped main board 51 and the lower Z-shaped main board 52 respectively, after placing the Z-shaped side panels 53 between the upper Z-shaped main board 51 and the lower Z-shaped main board 52, it is only necessary to drive the limit plate 37 on the corresponding side to move, and use the limit plate 37 to gradually push the Z-shaped side panels 53 to the predetermined installation position between the upper Z-shaped main board 51 and the lower Z-shaped main board 52, and finally ensure that the installation position of the Z-shaped side panels 53 is accurately aligned with the side walls of the upper and lower main boards, thereby completing the precise assembly of the Z-shaped side panels 53.

[0062] See also Figure 7 and Fig.10 As shown: the first limiting portion 362 is composed of a second slider 3621 slidably disposed on the second slide rail 361 and a limiting portion 3622 detachably disposed on the second slider 3621; a buffer sheet 3623 is also attached to the front end of the limiting portion 3622.

[0063] The limiting portion 3622 is a rectangular plate, and the limiting portion 3622 can be manually replaced with a rectangular plate of a corresponding shape according to the required supporting point. When the lower Z-shaped main board 52 is supported by the first limiting portion 362 and the second limiting portion 363, the top surfaces of the first limiting portion 362 and the second limiting portion 363 first abut against the lower surface of the lower Z-shaped main board 52, thereby achieving the supporting work of the lower Z-shaped main board 52. When it is necessary to further limit and support the lower Z-shaped main board 52, the first limiting portion 362 and the second limiting portion 363 will be in the synchronous drive The side walls of the side strips 56 of the lower Z-shaped main board 52 are driven by the actuator 364 to move away from each other and support each other, so that the side strips 56 on both sides of the lower Z-shaped main board 52 are further limited by the first limiting portion 362 and the second limiting portion 363 respectively; and the buffer plate 3623 fixedly arranged on the top surface of the limiting portion 3622 is used to directly contact the lower Z-shaped main board 52, so as to avoid supporting the lower Z-shaped main board 52 and causing wear to the side walls of the lower Z-shaped main board 52 when the first limiting portion 362 and the second limiting portion 363 are synchronously driven to move toward each other.

[0064] The first limiting portion 362 adopts a rectangular plate structure and has modular replacement capability. It can be manually replaced with a limiting plate 37 of a corresponding shape according to different support point requirements to adapt to various support requirements. When the lower Z-shaped main board 52 is supported by the first limiting portion 362 and the second limiting portion 363, the front end of the first limiting portion 362 first contacts the lower surface of the lower Z-shaped main board 52, thereby preliminarily completing the support positioning of the lower Z-shaped main board 52. When the lower Z-shaped main board 52 needs to be further limited and supported, the first limiting portion 362 and the second limiting portion 363 are synchronously moved away from each other under the drive of the synchronous driver 364, and the side walls of the lower Z-shaped main board 52 are supported from both sides to form a stable two-way limiting structure, thereby effectively improving the fixing strength and accuracy of the lower Z-shaped main board 52.

[0065] In addition, the buffer sheet 3623 fixedly arranged on the top surface of the limiting portion 3622 plays a protective role in the process of supporting and limiting the lower Z-shaped main board 52. Its material has high flexibility and wear resistance, and can effectively absorb the impact force and friction generated in the process of supporting and limiting, thereby avoiding wear or deformation of the side wall of the lower Z-shaped main board 52 due to supporting or limiting operations, thereby further extending the service life of the equipment and components.

[0066] Through the modular replacement of the fixing part 3622 and the control of the synchronous driver 364, the lower Z-shaped main board 52 is flexibly supported and fixed in both directions, which meets the operation requirements under different working conditions and significantly improves the assembly accuracy and stability. At the same time, the introduction of the buffer sheet 3623 effectively reduces the wear on the side wall of the lower Z-shaped main board 52 during the support and fixing operation.

[0067] See also Figure 1 and Fig. 9 As shown: the correction limit module 4 includes a support frame 41, a second linear drive unit 42, a second bidirectional synchronous limiting unit 43 and a supporting unit 44; the second linear drive unit 42 is vertically fixedly arranged on the base frame 1 through the support frame 41 and is located on one side of the adjustment module 2; the driving end of the second linear drive unit 42 is vertically arranged toward the base frame 1; the second bidirectional synchronous limiting unit 43 is horizontally fixedly arranged at the driving end of the second linear drive unit 42; the supporting unit 44 is fixedly arranged on the support frame 41 and is located below the second bidirectional synchronous limiting unit 43; the supporting unit 44 is provided with a supporting plate 441 which can longitudinally approach or move away from the second bidirectional synchronous limiting unit 43.

[0068] The structures of the first bidirectional synchronous limiting unit 36 ​​and the second bidirectional synchronous limiting unit 43 are substantially the same. The second bidirectional synchronous limiting unit 43 is also provided with a third limiting portion and a fourth limiting portion that can synchronously move toward or away from each other, and the third limiting portion and the fourth limiting portion are both modularly replaceable, and can be manually replaced with third limiting portions and fourth limiting portions of corresponding shapes according to different support point requirements to meet diverse limiting requirements. The difference is that the front ends of the third limiting portion and the fourth limiting portion are currently arranged at right angles and correspond to the two curved corners of the upper Z-shaped main board, respectively, and are used to limit and support the two curved corners of the upper Z-shaped main board, respectively. When it is necessary to fix the upper Z-shaped main board 51 through two sets of correction limit modules 4, the staff only needs to take the upper Z-shaped main board 51 and respectively correspond the two bent corners of the upper Z-shaped main board 51 to the limit ends of the two sets of correction limit modules 4 (i.e., the third limit part and the fourth limit part), and after the two bent corners of the upper Z-shaped main board 51 are respectively corrected by the third limit part and the fourth limit part, the second two-way synchronous limiting and fixing unit 43 is immediately driven to operate, and the third limit part and the fourth limit part are synchronously driven away from each other through the second two-way synchronous limiting and fixing unit 43, so that the third limit part and the fourth limit part are used to synchronously realize the internal support of the two bent corners of the upper Z-shaped main board 51, thereby realizing the limiting and fixing work of the upper Z-shaped main board 51.

[0069] See also Fig. 9As shown: the supporting unit 44 includes a third electric push rod 442, a guide frame 443 and a sliding frame 444; the guide frame 443 is arranged parallel to the long side direction of the support frame 41 on the outside of the support frame 41; the sliding frame 444 is slidingly arranged in the guide frame 443; the supporting plate 441 is vertically fixedly arranged on the side of the sliding frame 444 close to the second linear drive unit 42, and the supporting plate 441 is located below the second linear drive unit 42; the supporting plate 441 is arranged in a V shape and the included angle is a right angle; the supporting plate 441 is used to support the bend of the elbow bus duct 5; the third electric push rod 442 is fixedly arranged on the outside of the support frame 41 in a vertical state, and the output shaft of the third electric push rod 442 is vertically arranged toward the sliding frame 444 and fixedly connected to the sliding frame 444.

[0070] When the elbow bus duct 5 is assembled into the final step, that is, the two groups of Z-shaped side panels 53 are respectively installed on both sides of the upper Z-shaped main board 51 and the lower Z-shaped main board 52, in order to achieve further fastening operation so as to facilitate the final riveting by the rivet equipment, the staff only needs to connect the external power supply to drive the third electric push rod 442 to move. Through the pushing action of the third electric push rod 442, the sliding frame 444 and the supporting plate 441 fixedly arranged on one side of the sliding frame 444 are synchronously driven to slide along the preset track, and the supporting plate 441 then implements longitudinal support on the lower Z-shaped main board 52, so that the lower Z-shaped main board 52 is longitudinally close to the upper Z-shaped main board 51, thereby achieving a tighter connection between the upper Z-shaped main board 51, the lower Z-shaped main board 52 and the two groups of Z-shaped side panels 53, providing a stable connection structure for subsequent riveting operations.

[0073] S2: Subsequently, the operator takes the upper Z-shaped main board 51, places it horizontally between the two groups of the correction limit modules 4, and ensures that the bending corners of the upper Z-shaped main board 51 are in contact with the correction ends of the two groups of correction limit modules 4 respectively; and corrects and locks the upper Z-shaped main board 51 through the third limit part and the fourth limit part provided in the two groups of correction limit modules 4 respectively; when the two groups of upper Z-shaped main boards 51 are fixed, the two groups of correction limit modules 4 are synchronously driven to move, so that they are driven at a preset speed The upper Z-shaped main board 51 is longitudinally close to the lower Z-shaped main board 52; when the preset stroke position is reached, the two sets of correction limit modules 4 automatically stop moving to ensure that an appropriate installation gap is reserved between the upper Z-shaped main board 51 and the lower Z-shaped main board 52; the operator then takes the copper bar 54 and the two sets of limit blocks 55, and fixes the copper bar 54 between the upper Z-shaped main board 51 and the lower Z-shaped main board 52 in sequence, ensuring that the copper bar 54 is accurately positioned and the limit blocks 55 are firmly installed, thereby completing the installation steps of the copper bar 54;

[0074] S3: After completing the installation of the limit block 55 and the copper busbar 54, the operator takes the two sets of Z-shaped side panels 53 in turn and places them on both sides of the upper Z-shaped main board 51 and the lower Z-shaped main board 52 respectively; and drives the limit plate 37 to move, and through the pushing action of the limit plate 37, gradually pushes the two sets of Z-shaped side panels 53 along the preset trajectory to the correct assembly position, ensuring that the two sets of Z-shaped side panels 53 are completely flush with the side walls of the upper Z-shaped main board 51 and the lower Z-shaped main board 52 and fit tightly; under the action of the limit plate 37, the Z-shaped side panels 53 can achieve high-precision positioning and stable fixation;

[0075] S4: After the installation of the two groups of Z-shaped side panels 53 is completed, in order to further tighten the connection between the upper Z-shaped main board 51 and the lower Z-shaped main board 52 and the Z-shaped side panels 53, and to facilitate the final riveting operation, the operator needs to connect an external power supply to drive the third electric push rod 442 to move; through the output force of the third electric push rod 442, the sliding frame 444 and the supporting plate 441 fixed thereon are synchronously driven to slide along the preset track of the tooling platform; during the movement, the supporting plate 441 supports the lower Z-shaped main board 52 longitudinally, and gradually drives the lower Z-shaped main board 52 upward to approach the upper Z-shaped main board 51; during the supporting process, the tightness of the connection structure can be effectively guaranteed through the stable control of the sliding frame 444 and the precise bearing of the supporting plate 441;

[0076] S5: After the support plate 441 completes the longitudinal support of the lower Z-shaped main board 52, the operator needs to reconfirm the connection status of the upper Z-shaped main board 51 and the lower Z-shaped main board 52 and the two groups of Z-shaped side panels 53 to ensure that they have reached a stable state; finally, start the riveting equipment and perform the final riveting of the upper Z-shaped main board 51 and the lower Z-shaped main board 52 and the two groups of Z-shaped side panels 53 according to the riveting process preset on the tooling platform.
