Description

Technical Field

[0001] This invention relates to the field of aluminum profile splicing technology for flooring, and particularly to a tooling for splicing aluminum profiles for railway passenger car flooring. Background Technology

[0002] Railway passenger car floor aluminum profiles are aluminum alloy extruded profiles specifically used to manufacture the load-bearing structure of railway passenger car floor. They are the core structural components for achieving lightweight, high-strength, and integrated car bodies in modern rail vehicles. Railway passenger car floor aluminum profile splicing tooling refers to specialized process equipment used to splice, assemble, and weld multiple large aluminum profile floor pieces into a complete floor structure.

[0003] Railway passenger car floors are typically constructed from multiple heavy, large-section aluminum profiles. During installation and welding to the base frame, a crane is needed to lift the aluminum profiles onto a positioning fixture for placement before welding. Existing positioning fixtures for aluminum profile floor assembly require numerous clamping, pressing, and limiting components to stably position multiple profiles. However, the large number of clamping and limiting components complicates the overall fixture structure, resulting in numerous parts and increasing manufacturing costs. The process is complicated and difficult to assemble, and it also occupies a large installation space. On the other hand, in actual use, multiple clamping and limiting components need to be adjusted, locked and disassembled one by one. The steps are cumbersome, time-consuming and labor-intensive, which seriously affects the overall efficiency of aluminum profile feeding, positioning and welding. At the same time, too many limiting structures can make it difficult to unify the positioning accuracy of aluminum profiles, and the splicing gap between adjacent aluminum profiles is not easy to control, which can easily lead to uneven gaps and positional deviations, thus affecting the welding quality and splicing strength of the floor. Therefore, this application provides a splicing tool for aluminum profiles of railway passenger car floor to meet the requirements. Summary of the Invention

[0004] The technical problem to be solved by this invention is to provide a splicing fixture for aluminum profiles of railway passenger car flooring. By setting up an auxiliary limiting mechanism and a flipping limiting mechanism, the auxiliary limiting mechanism can further clamp and fix the base frame and floor body, allowing the base frame and floor body to be welded in a stable state. At the same time, the auxiliary limiting component can cooperate with the first limiting block and the second limiting block to position the base frame and floor body to the accurate welding position, ensuring welding quality. The above settings can solve the problem of existing clamping and limiting components being complex, numerous, and inconvenient to operate.

[0008] Optionally, the first insert has lightweight grooves at both the top and bottom, grinding discs are provided on both sides of the bottom of the first insert, the outer edge of the first insert is arc-shaped, and the cross-section of the first connecting block is L-shaped.

[0009] Optionally, a second sliding groove is provided on both sides of the third limiting block. A second sliding block adapted to the shape of the second sliding groove is installed in the second sliding groove. A second insert is fixedly connected to the side of the second sliding block away from the third limiting block. A second connecting block is rotatably connected to the side of the second insert away from the second sliding block. The cross-section of the second connecting block is L-shaped.

[0010] Optionally, the width of the second slider facing the second insert is greater than the width of the slider facing away from the second insert, and a first buffer cavity is provided on both sides of the second slider. The second slider is made of rubber.

[0011] Optionally, a first insert block is fixedly connected to the bottom of both sides of the second base plate. A third slot is provided on the first insert block. A second insert block that matches the shape of the third slot is inserted into the third slot. A first handle is fixedly connected to the side of the second insert block away from the third slot. A fourth slot that matches the shape of the first insert block is provided on the side of the first base plate close to the first insert block. A fifth slot that matches the shape of the second insert block is provided on the side of the first base plate close to the first insert block.

[0012] Optionally, the flipping limiting mechanism includes a third base plate installed on one side of the second base plate, a baffle rotatably connected to the side of the first base plate near the third base plate, a fourth limiting block installed on both sides of the first base plate, a fifth limiting block movably connected to the side of the fourth limiting block near the baffle, limiting grooves formed on both sides of the second base plate and the baffle, and a fourth connecting block fixedly connected to the side of the fifth limiting block and the fourth limiting block away from the first base plate, a second threaded block installed on the fourth connecting block, and an installation groove adapted to the shape of the second threaded block formed on the fourth connecting block.

[0013] Optionally, the first limiting block has an L-shaped cross-section, the second limiting block has a straight cross-section, and the third limiting block has a C-shaped cross-section. The thickness of the first insert is the same as the gap between two adjacent floor bodies.

[0014] Optionally, the outer walls of the first threaded block, the first handle, and the second threaded block are all provided with anti-slip textures with a depth of two millimeters, and a third connecting block is fixedly connected to one of the first limiting blocks and one of the second limiting blocks on the side away from the third base plate.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up auxiliary limiting mechanisms and flipping limiting mechanisms, not only can the base frame and floor body be further clamped and fixed by the auxiliary limiting mechanism, allowing the base frame and floor body to be welded in a stable state; at the same time, the auxiliary limiting components, in conjunction with the first limiting block and the second limiting block, can position the base frame and floor body to the accurate welding position, ensuring welding quality; in addition, by cooperating with the auxiliary limiting mechanism, the flipping limiting mechanism can stably limit and fix the base frame and floor body after the crane drives it to complete a 30° rotation and flip, facilitating rapid welding of the other side of the base frame and floor body, simplifying the operation process, and improving welding efficiency to a certain extent; the overall structure of this device is simple and convenient to use.

[0016] By incorporating a third limiting block, a first insert, and a second insert within the auxiliary limiting mechanism, multiple heavy aluminum profile flooring pieces with large cross-sectional areas can be quickly and securely fixed around their four sides. This results in fast positioning speed, simple operation, significantly reduced labor intensity for workers, and improved welding efficiency. Furthermore, the overall tooling structure is simple, eliminating the need for numerous complex clamping components. This simplifies the structure, reduces manufacturing costs, and facilitates disassembly and adjustment, solving the problems of complex traditional tooling structures and cumbersome operations. The combination of multiple limiting mechanisms and a top clamping structure effectively prevents the aluminum profiles from shaking, shifting, or warping during welding, resulting in high positioning accuracy and excellent welding formation, meeting the requirements of high-precision, mass production.

[0017] By incorporating a movable groove and a grinding disc within the auxiliary limiting mechanism, the rough outer wall of the grinding disc polishes the connecting surface of the floor body during the movement of the third limiting block. This removes impurities from the workpiece surface, preventing them from affecting the welding effect and resulting in a tighter connection between adjacent floor bodies. Simultaneously, the first insert of the component enables precise control of the welding gap between two adjacent floor bodies. This device employs a slidingly adjustable limiting component integrated with a spacing and grinding structure, which can precisely control the welding gap between adjacent aluminum profiles, ensuring uniformity, and also clean and polish the welding surface during positioning, improving welding fit and quality. Furthermore, the device can achieve simultaneous positioning, segmented welding, and cyclic operation of multiple aluminum profiles. The limiting component is flexibly adjustable to adapt to the limiting requirements of aluminum profiles of different sizes, making it highly versatile and widely applicable.

[0018] By incorporating a third base plate, a baffle, a second threaded block, and a fourth connecting block within the flipping limiting mechanism, not only can the tooling and its base frame and floor body be stably flipped 90°, but it also facilitates welding on the back of the base frame and floor body, thereby improving the convenience of welding operations and the overall structural stability.

[0019] In summary, this device can quickly and stably position multiple large aluminum profiles around their four sides through the cooperation of auxiliary limiting and flipping limiting mechanisms. It features a simple structure, convenient operation, and low cost. It can precisely control the welding gap and automatically clean the welding surface, effectively improving welding quality and positioning accuracy. It can also achieve stable locking by flipping, facilitating welding on both sides. The limiting components are flexibly adjustable, highly versatile, and support simultaneous positioning of multiple profiles and segmented cyclic operation, significantly improving welding efficiency and meeting the needs of high-precision, high-volume production.

[0029] like Figure 1 , Figure 2 , Figure 9 and Figure 12As shown, an embodiment of the present invention provides a splicing fixture for aluminum profiles of railway passenger car flooring, including a first base plate 1, a second base plate 2 mounted on the top of the first base plate 1, a support block 3 mounted on the top of the second base plate 2, a first limiting block 4 mounted on one side of the second base plate 2, a second limiting block 5 mounted on the other side of the second base plate 2, a base frame 24 mounted on the top of the support block 3, and a floor body 25 mounted on the top of the base frame 24. A third sliding groove 39 is provided on the side of the first base plate 1 and the second base plate 2 away from the first limiting block 4. A third slider 40 is slidably connected within the third sliding groove 39. A second buffer cavity 41 is provided on both sides of the third slider 40. A sixth limiting block 42 is fixedly connected to the side of the third slider 40 away from the second base plate 2. A second handle 43 is fixedly connected to the side of the limiting block 42 away from the second base plate 2; an auxiliary limiting mechanism is used to limit the base frame 24 and the floor body 25, and is connected to the second base plate 2; a flipping limiting mechanism is used to limit the flipped base frame 24 and the floor body 25, and is connected to the second base plate 2; one side of the first base plate 1 and the second base plate 2 are rotatably connected by a pivot, and the other side is connected by a plug-in assembly; the second base plate 2 is fixedly connected to the support blocks 3, of which there are six support blocks 3 in total, four of which are arranged at the four corners of the top of the second base plate 2, and the other two are arranged at the middle of the long side of the second base plate 2; when the base frame 24 and the floor body 25 are... During welding, the base frame 24 and the floor body 25 are first placed on top of the second base plate 2 using a crane and a loading assembly. Then, the base frame 24 and the floor body 25 are initially positioned using the first limiting block 4 and the second limiting block 5. The sixth limiting block 42 is moved closer to the base frame 24 by holding the second handle 43. During this process, the third slider 40 slides within the third groove 39, causing slight deformation of the second buffer cavity 41 due to compression. The top of the sixth limiting block 42 near the base frame 24 is inclined. As the sixth limiting block 42 gradually approaches the base frame 24, the bottom of the third slider 40 near the base frame 24 gradually comes into close contact with the side of the base frame 24 near the second limiting block 5, thus allowing for rapid welding of the base frame 24. The base frame 24 and the floor body 25 are limited on the side away from the first limiting block 4. The cooperation between the above structures ensures that the base frame 24 and the floor body 25 are limited and fixed on all four sides, thereby further stabilizing the base frame 24 and the floor body 25. The crane, the feeding assembly, and the base frame 24 and the floor body 25 are all existing mature technologies, and their specific structures and working principles will not be described in detail here. This device can further clamp and fix the base frame 24 and the floor body 25 through the auxiliary limiting mechanism, so that the base frame 24 and the floor body 25 can be welded in a stable state. At the same time, the auxiliary limiting assembly can cooperate with the first limiting block 4 and the second limiting block 5 to position the base frame 24 and the floor body 25 to the accurate welding position, ensuring the welding quality.Furthermore, by cooperating with the flipping limiting mechanism and the auxiliary limiting mechanism, the base frame 24 and the floor body 25 can be stably limited and fixed after the crane drives them to rotate 90° and flip, facilitating rapid welding of the other side of the base frame 24 and the floor body 25, simplifying the operation process, and improving welding efficiency to a certain extent. The device has a simple overall structure and is convenient and quick to use.

[0030] like Figures 1 to 7As shown, the auxiliary limiting mechanism includes a third limiting block 6 mounted on the second base plate 2. First sliders 7 are fixedly connected to the bottom of both sides of the third limiting block 6. A first screw hole 8 is provided on the first slider 7, and a first threaded block 9, matching the shape of the first screw hole 8, is installed inside the first screw hole 8. First sliding grooves 10, matching the shape of the first slider 7, are provided on both sides of the second base plate 2. Both the first slider 7 and the first sliding groove 10 have T-shaped cross-sections, allowing the first slider 7 to slide stably within the first sliding groove 10 without the risk of accidental detachment. The third limiting block 6 and the first slider 7 are integrally formed, resulting in better stability. The cross-section of the third limiting block 6 is C-shaped, facilitating use... The third limiting block 6 limits the sides of two adjacent floor bodies 25. The third limiting block 6 has a first slot 11 and a second slot 12. A first insert 13 is installed on the side of the third limiting block 6 closest to the first slot 11. A first connecting block 14, matching the shape of the second slot 12, is fixedly connected to the side of the first insert 13 closest to the second slot 12. The thickness of the first insert 13 is the same as the gap between the two adjacent floor bodies 25. Second sliding grooves 18 are provided on both sides of the third limiting block 6. A second sliding block 19, matching the shape of the second sliding groove 18, is installed within the second sliding groove 18. The side of the second sliding block 19 furthest from the third limiting block 6 is fixedly connected to... A second insert 20 is provided, and a second connecting block 21 is rotatably connected to the side of the second insert 20 away from the second slider 19. The third limiting block 6 further limits the two adjacent floor bodies 25 and both sides of the base frame 24. The first insert 13 is inserted into the first slot 11, which limits the first insert 13. The bottom of the first connecting block 14 is inserted into the second slot 12. Simultaneously, the first insert 13 is inserted between two adjacent floor bodies 25, limiting the two floor bodies 25 and leaving the required gap. The second insert 20 is moved to the gap on the side of the floor body 25 away from the first limiting block 4, limiting that side of the floor body 25, and is then connected to the first limiting block. When used in conjunction with block 4, the two floor bodies 25 closest to the first limiting block 4 can be kept in a stable state and accurate position. At this time, the two floor bodies 25 are spliced ​​together by a welding machine. The welding machine is a mature existing technology, and its working principle and specific structure will not be described in detail here. The third limiting block 6 and its components can be set to two, three or more sets. By installing and fixing multiple sets of the third limiting block 6 and related components at one time, more floor bodies 25 can be limited and fixed at the same time, and the splicing operation of multiple floor bodies 25 can be completed at one time. When fixing the third limiting block 6, it is only necessary to rotate the first threaded block 9, and use the thread engagement and friction to stably fix the first slider 7 in the first groove 10.Optionally, the first slider 7 can be fixed by one or more combinations of threaded locking, set screw clamping, elastic snap-fit, or plug-in pin positioning. This ensures reliable fixing while facilitating quick disassembly and position adjustment, meeting the needs of different working conditions. Welding is performed in segments. During welding, the positions of the first insert 13 and the second insert 20 are avoided first. After welding the remaining areas, the first insert 13 and the second insert 20 are removed before welding that section, thus quickly and stably joining adjacent floor bodies 25 together. The gap size remains uniform during welding, preventing uneven widths. Since the first slider 7 can slide within the first slide groove 10, adjusting the position of the first slider 7 within the first slide groove 10 can change the position of the third limiting block 6 and its components, allowing for multiple... The third limiting block 6 and related components can move flexibly to adapt to the limiting requirements of different sized floor panels 25. Simultaneously, the floor panels 25 can be spliced ​​in sections, achieving simultaneous limiting, fixing, and welding. The first slide groove 10 has a through-type structure on both sides, allowing the first slider 7 to be inserted or removed from either side of the first slide groove 10. This allows the limiting effect of the third limiting block 6 and its components on the floor panel 25 to be released after a section of welding is completed. At this point, adjacent floor panels 25 are basically welded, requiring only additional welding of unwelded areas. The removed set of third limiting blocks 6 and related components can be moved to the other side to limit and fix subsequent floor panels 25. This device, through the coordinated use of the above structures, offers greater flexibility, has a relatively simple overall structure, and is easy for operators to learn and use.

[0031] Furthermore, the third limiting block 6 has a movable groove 16 that matches the shape of the first connecting block 14. Both sides of the bottom of the first insert 13 are provided with grinding discs 17. The outer wall of the grinding discs 17 is rough. When the first slider 7 moves along the first sliding groove 10, the first insert 13 is first inserted into the first slot 11. The grinding discs 17 at the bottom of the first insert 13 contact the connecting surfaces of two adjacent floor bodies 25. During the movement, the grinding discs 17 grind the connecting surfaces of the floor bodies 25, preventing debris on the outer wall of the floor bodies 25 from affecting the welding, thus making the connection between the two adjacent floor bodies 25 tighter. Lightweight grooves 15 are provided at the top and bottom of the first insert 13 to facilitate operation of the first insert 13. Flipping it over: When the sanding disc 17 on the first insert 13 faces downwards, it can be used to sand the floor body 25; when the sanding disc 17 faces the top of the first insert 13, the first insert 13 is used to control the precise distance between two adjacent floor bodies 25. The outer edge of the first insert 13 is rounded and has no obvious sharp edges, which can prevent workers from accidentally scratching the first insert 13 when handling it. The cross-section of the first connecting block 14 is L-shaped, which facilitates further limiting of the first insert 13 using the first connecting block 14; when the second insert 20 on the third limiting block 6 is aligned with the gap face of the floor body 25 on the side away from the first limiting block 4, the lightweight groove 15 is moved to the gap on that side, and the first connecting block 14 is inserted into the movable groove. Within 16, the movable groove 16 limits the first connecting block 14; then, the first insert 13 moves along the guide of the movable groove 16, maintaining close contact between the connecting surface of the adjacent floor body 25 and the grinding disc 17 during the movement. The grinding of the connecting surface of the floor body 25 is completed by moving the first insert 13. The above structures cooperate with each other to improve the welding quality and are relatively easy to operate. The cross-section of the second connecting block 21 is L-shaped, and it can be easily folded into the top of the second insert 20 when not in use. When it is necessary to move the second insert 20 and place it in the gap between two adjacent floor bodies 25, rotate the second connecting block 21 so that it is located on one side of the second insert 20, and then push the second connecting block 21 to drive the second insert 20 to move, so that the second slider The second slider 19 slides within the second groove 18, facilitating the operation of the second insert 20. The width of the side of the second slider 19 facing the second insert 20 is greater than the width of the side facing away from the second insert 20. First buffer cavities 22 are provided on both sides of the second slider 19. The second slider 19 is made of rubber. The shape of the second slider 19 makes it easier to install the second slider 19 into the second groove 18. At the same time, the second slider 19 can undergo elastic deformation within a certain range. Therefore, when moving the second slider 19, the second slider 19 deforms preferentially from the first buffer cavity 22, facilitating movement. When not subjected to external force, the second slider 19 fits tightly against the second groove 18 under the action of restoring elasticity, thereby maintaining stability.

[0032] like Figures 9 to 12As shown, the aforementioned plug-in assembly comprises a first plug 28, a third slot 29, a second plug 30, a first handle 31, a fourth slot 32, and a fifth slot 33. The bottom sides of the second base plate 2 are fixedly connected to the first plug 28. A third slot 29 is provided on the first plug 28, and a second plug 30, matching the shape of the third slot 29, is inserted into the third slot 29. A first handle 31 is fixedly connected to the side of the second plug 30 away from the third slot 29. A fourth slot 32, matching the shape of the first plug 28, is provided on the side of the first base plate 1 closest to the first plug 28. A fifth slot 33, matching the shape of the first plug 28, is provided on the side of the first base plate 1 closest to the first plug 28. A fifth slot 33, matching the shape of the second plug 28, is provided on the side of the first base plate 1 closest to the first plug 28. The fifth slot 33, which is adapted to the shape of the insert block 30, allows the first insert block 28 to be inserted into the fourth slot 32. Then, the worker holds the first handle 31 and inserts the second insert block 30 through the fifth slot 33 and into the third slot 29. This allows the first base plate 1 and the second base plate 2 to be quickly and stably connected on the side away from their upper pivot, thus keeping the first base plate 1 and the second base plate 2 stable when welding the base frame 24 and the floor body 25. The structure is simple and easy to disassemble. The first insert block 28 is an arc-shaped structure that protrudes away from the upper pivot of the first base plate 1. When the second base plate 2 rotates along the pivot, the first insert block 28 can be inserted into the fourth slot 32.

[0033] like Figure 2 and Figures 8 to 13As shown, the flipping limiting mechanism includes a third base plate 26 installed on one side of the second base plate 2. A baffle 27 is rotatably connected to the side of the first base plate 1 near the third base plate 26. When the second base plate 2 rotates 90 degrees, its side wall near the third base plate 26 is tightly fitted with the third base plate 26. When the baffle 27 rotates along the first base plate 1, it rotates 90 degrees and is tightly fitted with the outer wall of the third base plate 26 near the baffle 27. At this time, the second base plate 2 and the baffle 27 change from a horizontal state to a vertical state. A fourth limiting block 35 is installed on both sides of the first base plate 1. A fifth limiting block 36 is movably connected to the side of the fourth limiting block 35 near the baffle 27. Limiting grooves 34 are opened on both sides of the second base plate 2 and the baffle 27. A fourth connecting block 37 is fixedly connected to the side of the fifth limiting block 36 and the fourth limiting block 35 away from the first base plate 1. A fourth connecting block 37 is installed on the fourth connecting block 37. The system is equipped with a second threaded block 38. A mounting groove matching the shape of the second threaded block 38 is provided on the fourth connecting block 37. The cross-sections of the fourth limiting block 35 and the fifth limiting block 36 are both L-shaped, and the side of the fourth limiting block 35 and the fifth limiting block 36 closest to the limiting groove 34 matches the shape of the limiting groove 34. After adjusting the angles of the second base plate 2 and the baffle 27, one side of the fourth limiting block 35 and the fifth limiting block 36 are inserted into the two limiting grooves 34 respectively. Then, the operator rotates the second threaded block 38, causing the two fourth connecting blocks 37 to move closer together under the action of the threads. This causes the second base plate 2 and the baffle 27 to tend to move closer together, further establishing a connection between the second base plate 2 and the baffle 27, thus ensuring the second base plate 2 remains stable in a vertical position. At this point, welding the back of the base frame 24 and the floor body 25 is more convenient, thereby increasing the ease of welding operations to a certain extent.

[0034] Furthermore, the first limiting block 4 has an L-shaped cross-section, and the second limiting block 5 is straight, facilitating the initial positioning of the base frame 24 and multiple floor bodies 25 using the first limiting block 4 and the second limiting block 5. The outer walls of the first threaded block 9, the first handle 31, and the second threaded block 38 are all provided with anti-slip textures with a depth of two millimeters to prevent workers' hands from slipping when operating the first threaded block 9, the first handle 31, and the second threaded block 38. A third connecting block 23 is fixedly connected to one of the first limiting blocks 4 and one of the second limiting blocks 5 on the side away from the third base plate 26. By using a crane to hook the third connecting block 23, the second base plate 2 can be easily lifted, thereby facilitating the adjustment of the angle of the second base plate 2 and its various structures, achieving a 90-degree flipping effect; such as Figure 13 As shown, top fixing components are installed on both sides of the third limiting block 6. The top fixing components include a knob and a pressure plate. The top of both sides of the third limiting block 6 is provided with threaded grooves that match the shape of the knob. By adjusting the knob, the pressure plate presses the top of the floor body 25 tightly, which can further ensure the stability of the floor body 25.

[0035] The working principle of the technical solution provided by this invention is as follows: In use, the workpiece base frame 24 and the floor body 25 are first placed on top of the second base plate 2 using a crane and a loading assembly. Then, the base frame 24 and floor body 25 are initially positioned using the first limiting block 4 and the second limiting block 5. The operator holds the second handle 43, causing the sixth limiting block 42 to move closer to the base frame 24. During this process, the third slider 40 slides within the third slide groove 39, and the second buffer cavity 41 is slightly deformed due to compression. Because the top of the sixth limiting block 42 near the base frame 24 is an inclined surface, as the sixth limiting block 42 gradually approaches the base frame 24, the third slider 40 moves closer to the base frame 24. The bottom of one side gradually comes into close contact with the side of the base frame 24 near the second limiting block 5, thereby quickly limiting the side of the base frame 24 and the floor body 25 away from the first limiting block 4. With the cooperation of the above structure, the base frame 24 and the floor body 25 are limited and fixed on all sides, so that the workpiece maintains initial stability during the welding process. Then, the third limiting block 6 further limits the two adjacent floor bodies 25 and the two sides of the base frame 24. The first insert 13 is inserted into the first slot 11, and the first slot 11 limits the first insert 13. The bottom of the first connecting block 14 is inserted into the second slot 12. At the same time, the first... Insert 13 is inserted between two adjacent floor bodies 25 to limit the two floor bodies 25 and leave a uniform welding gap; the second insert 20 is moved to the gap on the side of the floor body 25 away from the first limiting block 4 to limit that side, and works in conjunction with the first limiting block 4 to keep the two floor bodies 25 closest to the first limiting block 4 stable and accurately positioned, at which point the adjacent floor bodies 25 can be spliced ​​together by a welding machine; multiple sets of the third limiting block 6 and its components can be set to limit and fix multiple floor bodies 25 at one time, realizing the synchronous splicing of multiple workpieces; when fixing the third limiting block 6, rotate The first threaded block 9 is moved, and the first slider 7 is stably fixed in the first slide groove 10 through the thread engagement and friction. The first slide groove 10 has a through structure on both sides, and the first slider 7 can slide along the first slide groove 10 to adjust the position of the third limiting block 6 and its components to adapt to different sizes of floor body 25. It can also perform limiting and welding operations on the workpiece in different areas. After a section of welding is completed, the third limiting block 6 and related components can be removed from the first slide groove 10 and moved to the subsequent station to continue limiting and fixing new workpieces, so as to achieve continuous operation. When moving along the first slide groove 10, the first insert 13 can be moved synchronously.When the grinding disc 17 on the first insert 13 faces downwards, the grinding disc 17 contacts the connecting surfaces of the two adjacent floor bodies 25, grinding the connecting surfaces during movement to remove debris from the outer wall and improve the welding fit. When the grinding disc 17 faces the top of the first insert 13, the first insert 13 is used to control the precise spacing between the two adjacent floor bodies 25, ensuring uniform gaps. Welding is performed in segments, first avoiding the positions of the first insert 13 and the second insert 20. After the remaining areas are welded, the first insert 13 and the second insert 20 are removed, and then the area is welded again, allowing the adjacent floor bodies 25 to be quickly and stably spliced ​​into one piece. Then, the connection between the spliced ​​floor body 25 and the base frame 24 is welded. During the flip welding, the third connecting block 23 is hooked by a crane, the second base plate 2 is lifted as a whole and rotated 90° to flip over. After flipping... The side wall of the second base plate 2 closest to the third base plate 26 is tightly fitted to the third base plate 26. After the baffle 27 is rotated 90°, it also fits into the third base plate 26, changing the second base plate 2 and the baffle 27 from a horizontal state to a vertical state. After adjusting the angle of the second base plate 2 and the baffle 27, one side of the fourth limiting block 35 and the fifth limiting block 36 are respectively inserted into the two limiting grooves 34. The second threaded block 38 is rotated, causing the two fourth connecting blocks 37 to approach each other under the action of the threads, thereby driving the second base plate 2 and the baffle 27 to move closer together and form a stable connection, so that the second base plate 2 can be reliably positioned in a vertical state, which facilitates welding of the back of the base frame 24 and the floor body 25. In addition, top fixing components are provided on both sides of the third limiting block 6. By adjusting the knob, the pressure plate is pressed tightly against the top of the floor body 25, which further improves the stability of the workpiece during the welding process and ensures the welding quality.
