Description

Technical Field

[0001] This application relates to the technical field of building construction, and in particular to a grid processing mold fixture. Background Technology

[0002] In the field of grating processing, grating, as an important supporting structure, is widely used in tunnel support, building foundation pit support, and other projects. With the increasing precision requirements of grating arch structures in engineering projects, the processing quality of the grating directly affects the safety and stability of the project. Currently, the traditional mold is mainly used for positioning and processing of the grating. However, the worktable and support frame of the traditional mold are mostly fixed integrated structures. During grating processing, the curvature of the worktable cannot be adjusted slightly according to processing needs. To ensure the processing quality of the grating, different molds need to be changed, which not only increases the purchase cost of equipment but also prolongs the processing preparation time, reduces production efficiency, and seriously restricts the progress of the project. Utility Model Content

[0003] In order to improve the problem that the worktable and support frame of traditional grating molds are mostly fixed integrated structures, and the curvature of the worktable cannot be adjusted slightly according to the processing requirements during the grating processing, which increases costs and reduces production efficiency, this application provides a grating processing grating mold fixture.

[0004] This application provides a grid processing mold fixture, which adopts the following technical solution: A grid processing mold fixture includes an arc-shaped worktable and multiple support frames. The multiple support frames are spaced apart at the bottom of the arc-shaped worktable along the extension direction of the arc-shaped worktable. Multiple sets of adjustment components for adjusting and fixing the curvature of the arc-shaped worktable are installed on the support frames. Multiple clamping components for positioning the grid are detachably provided on the side of the arc-shaped worktable away from the support frames. The adjustment assembly includes a first threaded rod and a second threaded rod. The support frame has multiple adjustment holes. The first and second threaded rods are movably disposed within the adjustment holes. The arc-shaped worktable is located between the first and second threaded rods. A first limiting sleeve is sleeved onto one end of the first threaded rod, and a second limiting sleeve is sleeved onto one end of the second threaded rod. The first limiting sleeve is located on one side of the arc-shaped worktable. The first threaded rod passes through the adjustment hole and is threaded with a first locking element. The second limiting sleeve is located on the other side of the arc-shaped worktable. The second threaded rod passes through the adjustment hole and is threaded with a second locking element to fix the arc-shaped worktable.

[0005] By adopting the above technical solution, the arc-shaped worktable provides an arc-shaped reference surface for grating processing. Multiple support frames form a stable support structure. The adjustment component adjusts the position of the first and second threaded rods within the adjustment holes. Combined with the first and second limiting cylinders clamping the arc-shaped worktable from both sides, precise adjustment of the curvature of the arc-shaped worktable is achieved. The position is then locked by the first and second locking components, meeting the processing requirements of gratings with different curvatures. The detachable clamping components can be flexibly replaced according to the grating specifications, achieving precise positioning of the grating. The overall structure balances curvature adjustability and positioning stability, significantly improving the equipment's versatility and processing accuracy.

[0006] Optionally, the adjustment hole is configured as an elongated hole.

[0007] By adopting the above technical solution, the elongated hole provides the first and second threaded rods with a longer movement trajectory and a more flexible adjustment range, enabling the threaded rods to adjust their positions within a wider range to adapt to the curvature changes of the arc-shaped worktable. At the same time, the elongated hole helps the threaded rods maintain a stable direction of movement during adjustment, avoiding jamming or deviation during the adjustment process.

[0008] Optionally, baffles are installed at both ends of the arc-shaped worktable, and stiffeners are connected between the baffles and the side of the arc-shaped worktable.

[0009] By adopting the above technical solution, the baffle can effectively block the axial sliding of components during the processing of the grille, preventing the processed parts from falling off from both ends of the arc-shaped worktable and ensuring processing safety. The stiffening ribs enhance the connection strength between the baffle and the arc-shaped worktable, preventing the baffle from deforming or loosening due to stress, ensuring that the baffle can play a stable role in the long term. At the same time, the stiffening ribs can also disperse the impact force generated during processing and improve the overall structural rigidity of the arc-shaped worktable.

[0010] Optionally, the clamp assembly includes a first mounting plate, a second mounting plate, and a jig for positioning the grid. One end of the jig is connected to the first mounting plate, and the other end is connected to the second mounting plate. A plurality of first connectors are mounted on the first mounting plate, and a plurality of second connectors are mounted on the second mounting plate. A first connecting hole is provided on one side of the arc-shaped worktable, and a second connecting hole is provided on the other side. The first connectors pass through the first connecting holes and are connected to first fasteners to fix the first mounting plate. The second connectors pass through the second connecting holes and are connected to second fasteners to fix the second mounting plate.

[0011] By adopting the above technical solution, the first mounting plate and the second mounting plate form a double-point fixing structure. The first connector and the second connector respectively cooperate with the first connecting hole and the second connecting hole of the arc-shaped worktable, and are then locked by the first fastener and the second fastener to achieve a stable connection between the jig and the arc-shaped worktable. This detachable connection method makes it easy to quickly change jigs of different specifications according to the grid model. At the same time, the multi-point fixing structure ensures that the jig will not shift or shake during the processing, thus ensuring positioning accuracy.

[0012] Optionally, the frame includes a first horizontal bar, a first vertical bar, a second vertical bar, a second horizontal bar, and a third horizontal bar. One end of the first horizontal bar is connected to the first mounting plate, and the other end is connected to the second mounting plate. The first vertical bar is mounted on one end of the first horizontal bar, and the second vertical bar is mounted on the other end. The end of the second vertical bar away from the first horizontal bar is connected to the first vertical bar through the second horizontal bar. The third horizontal bar is mounted on the end of the first vertical bar away from the first horizontal bar. The first horizontal bar, the first vertical bar, the second horizontal bar, and the second vertical bar form a first positioning space for positioning the main reinforcement of the grid. A first connecting rod and a second connecting rod are provided in the first positioning space to form multiple V-shaped grooves in the first positioning space. The second horizontal bar, the third horizontal bar, and the first vertical bar form a second positioning space for positioning the V-shaped reinforcement in the grid.

[0013] By adopting the above technical solution, the rod-shaped structure of the jig forms functional zones through reasonable layout. The first positioning space is used for positioning the main ribs of the grid, and the multiple V-shaped grooves therein can independently limit the main ribs to prevent them from shifting during welding. The second positioning space realizes the precise positioning of the figure-eight ribs. This partitioned positioning setting enables all components of the grid to obtain stable support at the same time, improving the overall processing accuracy of the grid.

[0014] Optionally, the first crossbar, the second crossbar, and the third crossbar are all provided with multiple positioning slots spaced apart.

[0015] By adopting the above technical solution, the positioning grooves can axially limit the grid components placed on the crossbar, preventing the grid components from sliding due to external forces during processing, and further improving positioning stability. At the same time, the spaced positioning grooves can accommodate grid components with different spacing requirements, enhancing the adaptability of the jig to grids of different specifications and reducing the frequency of jig replacement.

[0016] Optionally, the end of the first upright near the third crossbar is configured as a telescopic pole.

[0017] By adopting the above technical solution, the telescopic rod structure allows the height of the third crossbar to be adjusted according to the specifications of the figure-eight ribs, thereby changing the size of the second positioning space to adapt to the positioning requirements of different models of figure-eight ribs, thus enhancing the versatility of the jig, eliminating the need to design jigs separately for different specifications of figure-eight ribs, and reducing equipment costs.

[0018] Optionally, the arc-shaped worktable is an I-beam.

[0019] By adopting the above technical solutions, the I-beam possesses excellent bending resistance and structural strength, capable of withstanding welding stress and component weight during grating processing, ensuring that the curved worktable is not easily deformed during long-term use and maintaining a stable curved reference surface. Simultaneously, the cross-sectional characteristics of the I-beam facilitate connection with support frames and clamping assemblies, simplifying the installation structure and improving the overall structural stability of the device.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. The curvature of the arc-shaped worktable can be flexibly adjusted by adjusting the components. The worktable can be slightly adjusted according to the processing requirements without replacing it, so as to adapt to the grid processing requirements, reduce equipment costs, shorten changeover time, and improve production efficiency. 2. The partitioned positioning and detachable structure of the clamping assembly can achieve precise positioning of each component of the grid and can be quickly replaced according to the grid specifications, thus improving processing accuracy and equipment versatility.

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0027] This application discloses a grid processing mold fixture, referring to... Figures 1-3 The grid processing mold fixture includes an arc-shaped worktable 1 and multiple support frames 2. The multiple support frames 2 are spaced apart at the bottom of the arc-shaped worktable 1 along the extension direction of the arc-shaped worktable 1. Multiple sets of adjustment components 4 for adjusting and fixing the curvature of the arc-shaped worktable 1 are installed on the support frames 2. Multiple clamping components 3 for positioning the grid are detachably installed on the side of the arc-shaped worktable 1 away from the support frames 2. The adjustment assembly 4 includes a first threaded rod 41 and a second threaded rod 42. The support frame 2 has multiple adjustment holes 21. The first threaded rod 41 and the second threaded rod 42 are movably disposed in the adjustment holes 21. The arc-shaped worktable 1 is located between the first threaded rod 41 and the second threaded rod 42. A first limiting cylinder 411 is sleeved and connected to one end of the first threaded rod 41, and a second limiting cylinder 421 is sleeved and connected to one end of the second threaded rod 42. The first limiting cylinder 411 is located on one side of the arc-shaped worktable 1. The first threaded rod 41 passes through the adjustment hole 21, and a first locking member 412 is threadedly connected to the first threaded rod 41. The second limiting cylinder 421 is located on the other side of the arc-shaped worktable 1. The second threaded rod 42 passes through the adjustment hole 21, and a second locking member 422 is threadedly connected to the second threaded rod 42 to fix the arc-shaped worktable 1.

[0028] In this grid processing mold fixture, the arc-shaped worktable 1 matches the curvature of the grid to be processed. The arc-shaped worktable 1 provides an arc-shaped support surface for the main ribs and ribs of the grid, ensuring that the grid can fit the arc-shaped contour of the arc-shaped worktable 1 during processing. The arc-shaped worktable 1 provides a foundation for the installation of the support frame 2 and also provides a detachable connection carrier for the fixture assembly 3. The support frame 2 provides vertical support for the arc-shaped worktable 1, distributing the weight load of the arc-shaped worktable 1 and the grille during processing, and maintaining the stability of the arc-shaped reference surface. The support frame 2 also provides an installation platform for the adjustment component 4, ensuring that the adjustment component 4 can act stably on the arc-shaped worktable 1. The spaced support frame 2 structure can bear the load evenly, adapt to arc-shaped worktables 1 of different lengths, enhance the adaptability of the device to grilles of different specifications, and eliminate the need to set up separate support structures for grilles of different lengths. In the adjusting assembly 4, the first threaded rod 41 can move within the adjusting hole 21 to change the support position of the arc-shaped worktable 1. The first threaded rod 41, in conjunction with the second threaded rod 42, clamps and adjusts the position of both sides of the arc-shaped worktable 1. By moving, the local curvature of the arc-shaped worktable 1 is changed, solving the problem that the curvature of traditional molds cannot be adjusted due to its fixed curvature. The threaded structure of the first threaded rod 41 facilitates its engagement with the first locking member 412 to achieve position locking. Specifically, the first locking member 412 locks the position of the first threaded rod 41 by tightening it to fit against the surface of the support frame 2, preventing the threaded rod from loosening after adjustment. This ensures that the position of the arc-shaped worktable 1 remains stable and does not shift after adjustment to the target curvature, avoiding curvature changes caused by vibration during processing and ensuring the processing accuracy of the grille. The detachable nature of the first locking member 412 facilitates subsequent adjustment of the curvature, meeting the processing needs of multiple batches of grilles of different specifications.

[0029] The first limiting sleeve 411 can increase the contact area between the first threaded rod 41 and the arc-shaped worktable 1, avoid the end of the threaded rod directly pressing the arc-shaped worktable 1 to cause local deformation, and maintain the accuracy of its arc-shaped reference surface; at the same time, the first limiting sleeve 411 can enhance the support stability of the threaded rod on the arc-shaped worktable 1, prevent the threaded rod from losing contact with the worktable during the adjustment process, and ensure the effective transmission of the adjustment action. The second threaded rod 42 is symmetrically arranged with the first threaded rod 41. One end of the second threaded rod 421 contacts the other side of the arc-shaped worktable 1, and the other end passes through the adjustment hole 21 and is connected to the second locking member 422. It is used to adjust the position of the other side of the arc-shaped worktable 1 and forms a bidirectional adjustment structure with the first threaded rod 41. Together with the first threaded rod 41, it clamps the arc-shaped worktable 1 to ensure that the forces on both sides of the arc-shaped worktable 1 are balanced and to avoid tilting or deformation of the worktable caused by unilateral adjustment. Through synchronous or differential adjustment on both sides, the curvature change of the arc-shaped worktable 1 can be precisely controlled to meet the processing requirements of different curvature grids without changing the worktable and shortening the changeover time.

[0030] The second limiting cylinder 421 is used to increase the contact area, protect the arc-shaped worktable 1 and provide stable support, achieving uniform protection and stable support for both sides of the arc-shaped worktable 1, avoiding damage to the worktable or adjustment deviation caused by uneven force on one side, and ensuring the accuracy of curvature adjustment and the service life of the worktable. The second locking element 422 is used to lock the position of the second threaded rod 42, achieving double locking on both sides of the arc-shaped worktable 1, further enhancing the stability of curvature fixation; the threaded connection structure facilitates quick tightening or disassembly, improving adjustment and shape change efficiency, and solving the problem of time-consuming mold replacement in traditional methods.

[0031] The adjusting hole 21 provides a moving channel for the first threaded rod 41 and the second threaded rod 42, restricting the direction of movement of the threaded rods and ensuring that the threaded rods move along a preset trajectory during the adjustment process. The opening position and size of the adjusting hole 21 determine the adjustment range of the threaded rods, and thus determine the curvature adjustment range of the arc-shaped worktable 1, adapting to the processing of more specifications of grids and enhancing the versatility of the device. The clamping assembly 3 is used to position the main ribs, herringbone ribs and other components of the grid, ensuring that each component maintains its preset relative position during processing, thereby improving the processing accuracy of the grid. The detachable setting allows for the replacement of the appropriate clamping assembly 3 according to the grid specifications, without having to replace the entire mold, thus reducing equipment investment. At the same time, the quick disassembly and assembly structure shortens the changeover time, improves production efficiency, and solves the problems of poor adaptability and slow changeover of traditional molds. The grating processing mold fixture provides stable support for the arc-shaped worktable 1 through the support frame 2. The curvature of the arc-shaped worktable 1 is precisely adjusted and fixed by the adjustment component 4. Then, the detachable clamping component 3 positions the various components of the grating. Finally, it provides a precise and stable processing benchmark for gratings with different curvatures and specifications, realizing efficient and high-quality grating processing. During the grating processing, the curvature of the worktable can be adjusted slightly by the adjustment component 4 according to the processing requirements to ensure the processing quality of the grating. There is no need to change different molds, which reduces the purchase cost of equipment, reduces construction preparation time, improves production efficiency, and thus improves the progress of the project. refer to Figure 2 and Figure 3 The adjustment hole 21 is set as an elongated hole, which provides a moving channel for the first threaded rod 41 and the second threaded rod 42. Its elongated structure can provide more moving space for the threaded rod in a specific direction, thereby expanding the curvature adjustment range of the arc-shaped worktable 1, which can adapt to the processing needs of more grids with different curvature specifications and enhance the versatility of the device. At the same time, the movement trajectory of the threaded rod is restricted by its own hole wall, ensuring that the threaded rod can only be adjusted along the length direction of the elongated hole, avoiding lateral deviation.

[0032] refer to Figure 1 and Figure 2 Both ends of the arc-shaped worktable 1 are equipped with baffles 13. The baffles 13 are blocking structures at the ends of the arc-shaped worktable 1, which can axially limit the grid components placed on the arc-shaped worktable 1. When the grid components are processed on the arc-shaped worktable 1, they are prone to axial displacement due to factors such as welding operation vibration and personnel touching them. The baffles 13 can effectively prevent the components from sliding off from both ends of the worktable, avoiding damage to the components or affecting the processing progress, and ensuring the safety and continuity of the processing. A stiffening rib 14 connects the baffle 13 to the side of the arc-shaped worktable 1. The stiffening rib 14 is a reinforcing structure that enhances the connection strength between the baffle 13 and the arc-shaped worktable 1, while also dispersing the external forces borne by the baffle 13, preventing deformation due to concentrated stress. The stiffening rib 14, through a triangular stabilizing structure, transfers the force on the baffle 13 to the side of the arc-shaped worktable 1, significantly improving the baffle 13's resistance to deformation and ensuring that the baffle 13 remains upright after long-term use, without affecting the limiting effect.

[0033] The arc-shaped worktable 1 is made of I-beams. The I-beams provide a stable arc-shaped load-bearing foundation for grating processing through their I-shaped cross-section structure. At the same time, it serves as a connecting carrier, adapting to the support frame 2 for support installation and the detachable connection of the clamp assembly 3.

[0034] Specifically, the H-beam's cross-section consists of a web and upper and lower flanges. The flanges effectively distribute the vertical load during the grating processing, while the web enhances the overall shear resistance, preventing the worktable from bending or deforming due to excessive load. This ensures that even after long-term processing of heavy grating components, a stable arc-shaped reference surface can still be maintained. Simultaneously, the upper and lower flanges of the H-beam have flat mounting surfaces, facilitating the installation of the support frame 2 on the bottom flange and ensuring a secure connection between the support frame 2 and the worktable. The top flange can have connection holes, providing a suitable base for the detachable installation of the clamping assembly 3. This eliminates the need for additional welding of mounting bases, simplifying the assembly structure and reducing the risk of worktable deformation due to additional welding, thus ensuring arc-shaped accuracy.

[0035] The H-beam is made of high-strength steel, which has excellent rigidity and fatigue resistance. After being formed into an arc shape, it is not easy to undergo secondary deformation due to environmental temperature changes, long-term stress and other factors. It can maintain the preset arc shape for a long time, ensuring that the benchmark of each batch of grating processing is consistent. refer to Figure 1 and Figure 4 The clamp assembly 3 includes a first mounting plate 31, a second mounting plate 32, and a jig 33 for positioning the grid. One end of the jig 33 is connected to the first mounting plate 31, and the other end is connected to the second mounting plate 32. Multiple first connectors 311 are mounted on the first mounting plate 31, and multiple second connectors 321 are mounted on the second mounting plate 32. A first connecting hole 11 is opened on one side of the arc-shaped worktable 1, and a second connecting hole 12 is opened on the other side. The first connector 311 passes through the first connecting hole 11 and is connected to a first fastener 312 to fix the first mounting plate 31. The second connector 321 passes through the second connecting hole 12 and is connected to a second fastener 322 to fix the second mounting plate 32.

[0036] The first mounting plate 31 serves as one side carrier connecting the jig 33 to the arc-shaped worktable 1, providing a stable mounting support point for the jig 33 and transferring the load on the jig 33 to the arc-shaped worktable 1. The second mounting plate 32 serves as the other side carrier connecting the jig 33 to the arc-shaped worktable 1, forming a double-sided support for the jig 33 together with the first mounting plate 31. This ensures that the jig 33 is subjected to balanced forces, preventing deformation of the jig 33 due to unilateral fixation. The double-sided support structure significantly improves the stability of the jig 33, maintaining its position even during stress operations such as welding, further ensuring the accuracy of the grid component positioning and reducing processing errors. The first connector 311 is an intermediate component connecting the first mounting plate 31 and the arc-shaped worktable 1, transmitting the locking force of the first fastener 312 to achieve a detachable connection between the two. This detachable design allows for the replacement of different jigs 33 according to the grid specifications without requiring modification of the arc-shaped worktable 1, enhancing the device's adaptability and facilitating later maintenance or adjustment of the jig position, thus improving operational flexibility. The second connector 321 is an intermediate component connecting the second mounting plate 32 and the arc-shaped worktable 1, and works with the second fastener 322 to fix and disassemble the two. The second connector 321 and the first connector 311 together ensure the reliability of the connection on both sides of the jig 33, avoiding the jig 33 from loosening due to the failure of one side connector; the symmetrical detachable structure makes the jig 33 easier to assemble and disassemble, and no complicated operation is required during model change, shortening the model change time, improving production efficiency, and meeting the needs of continuous processing of multi-specification grids. The first fastener 312 is threadedly connected to the first connector 311. By tightening, the first mounting plate 31 is tightly fitted to the side of the arc-shaped workbench 1, locking the position of the first mounting plate 31 and preventing the mounting plate from loosening during processing, thereby maintaining the stability of the jig 33. The threaded connection locking method facilitates precise control of the tightness, ensuring both connection strength and avoiding deformation of the mounting plate or workbench due to over-tightening, thus ensuring structural integrity. The second fastener 322 cooperates with the second connector 321, and by tightening, the second mounting plate 32 is brought into contact with the other side of the arc-shaped worktable 1, locking the position of the second mounting plate 32. Together with the first fastener 312, this achieves double-sided locking of the jig 33, further enhancing the stability of the connection between the jig 33 and the arc-shaped worktable 1. Even after long-term, high-frequency use, the connection can be maintained, reducing maintenance frequency. The detachable threaded structure facilitates the later disassembly and replacement of the jig 33, making operation simple and convenient, reducing the difficulty of changeover, and improving the efficiency and economy of the device.

[0037] The jig 33 is a direct positioning structure for the grid components, connected between the first mounting plate 31 and the second mounting plate 32. It forms a suitable positioning space according to the setting position of the grid main bars, rib bars and other components, ensuring that each component maintains the preset relative position and posture during processing, which greatly improves the processing accuracy of the grid. The integrated connection between the jig 33 and the mounting plate makes the positioning structure more stable, able to withstand the external force during component placement and welding, maintain the positioning state unchanged, and ensure that the processed grid meets the processing requirements and is suitable for the structural needs of support scenarios such as tunnels and foundation pits. refer to Figure 4 The frame 33 includes a first crossbar 331, a first upright 332, a second upright 333, a second crossbar 334, and a third crossbar 335. One end of the first crossbar 331 is connected to the first mounting plate 31, and the other end is connected to the second mounting plate 32. The first upright 332 is mounted on one end of the first crossbar 331, and the second upright 333 is mounted on the other end. The end of the second upright 333 away from the first crossbar 331 is connected to the first upright 332 through the second crossbar 334. A third horizontal bar 335 is installed at the end away from the first horizontal bar 331; the first horizontal bar 331, the first vertical bar 332, the second horizontal bar 334, and the second vertical bar 333 enclose a first positioning space for positioning the main reinforcement of the grid. A first connecting rod 336 and a second connecting rod 337 are provided in the first positioning space to form multiple V-shaped grooves. The second horizontal bar 334, the third horizontal bar 335, and the first vertical bar 332 enclose a second positioning space for positioning the V-shaped reinforcement in the grid.

[0038] The first horizontal bar 331 serves as the bottom foundation frame of the jig 33, bearing the load of all vertical components of the jig 33 and transferring it to the mounting plate. It also provides an installation reference for the first and second uprights 332, determining their relative distance. The first upright 332 is the vertical support component of the jig 33, defining the boundaries of the first and second positioning spaces, determining their relative positions, accommodating the assembly relationship of the main ribs and the ribs, avoiding spatial interference during positioning of the two components, and ensuring smooth processing operations. The second upright 333, together with the first upright 332, the first horizontal bar 331, and the second horizontal bar 334, forms a first positioning space, defining the lateral boundary of the first positioning space. This ensures that the main reinforcement bars of the grid can be placed within the positioning space, preventing the main reinforcement bars from swaying due to excessive width or from being unable to be installed due to excessive narrowness. The vertical support of the second upright 333 enhances the stability of the second horizontal bar 334, preventing the second horizontal bar 334 from bending and deforming when bearing the weight of the main reinforcement bars, and maintaining the shape accuracy of the first positioning space. The second horizontal bar 334 forms the top boundary of the first positioning space and the bottom boundary of the second positioning space, providing bidirectional vertical restraint to the main ribs at the bottom of the grille and offering bottom support for the grille's ribs. The third horizontal bar 335 forms the top boundary of the second positioning space, defining the top position of the ribs and providing support for the main ribs at the top of the grille. The first link 336 and the second link 337 are disposed inside the first positioning space. The first link 336 and the second link 337 are intersected and distributed to divide the first positioning space into multiple independent areas. At the same time, they form one side boundary of the V-groove, realizing the independent positioning of multiple grid main bars and avoiding positional displacement caused by contact between the main bars. The V-groove can automatically center the cylindrical main bars. Even if there is a slight deviation in the diameter of the main bar, the inclined surface of the V-groove can fit against the surface of the main bar to ensure that the central axis position of each main bar is consistent, which greatly improves the positioning accuracy of the main bars. Multiple positioning slots 3311 are spaced apart on the first horizontal bar 331, the second horizontal bar 334, and the third horizontal bar 335. The positioning slots 3311 of the first horizontal bar 331 serve as limiting structures for the main reinforcement bars at the bottom of the grid. The contour of the slot constrains the lateral and longitudinal displacement of the main reinforcement bars, while providing an independent placement position for each main reinforcement bar and clearly defining the distribution spacing of the main reinforcement bars. The positioning slots 3311 of the second horizontal bar 334 can be spaced apart on the upper and lower surfaces of the second horizontal bar 334. The positioning slots 3311 on the upper surface provide limiting for the bottom of the ribs, while the positioning slots 3311 on the lower surface correspond vertically to the positioning slots 3311 of the first horizontal bar 331, jointly constraining the vertical position of the main reinforcement bars and reducing the displacement of the main reinforcement bars caused by welding stress.

[0039] The positioning grooves 3311 of the third horizontal bar 335 are spaced apart on the upper and lower surfaces of the third horizontal bar 335. The positioning grooves 3311 on the upper surface of the third horizontal bar 335 correspond vertically to the positioning grooves 3311 on the upper surface of the second horizontal bar 334. As a limiting structure for the top of the ribs, the grooves constrain the top position of the ribs and define the vertical height and horizontal spacing of the ribs. The positioning grooves 3311 on the lower surface of the third horizontal bar 335 are the limiting structure for the main ribs at the top of the grid. The groove contours constrain the horizontal and vertical displacement of the main ribs, providing a more accurate and stable positioning reference for grid processing. The end of the first upright 332 near the third horizontal bar 335 is configured as a telescopic rod. This telescopic rod can adjust its length to change the vertical distance between the third horizontal bar 335 and the second horizontal bar 334, thereby adjusting the height of the second positioning space formed by the second horizontal bar 334, the third horizontal bar 335, and the first upright 332 to accommodate the positioning requirements of different specifications of herringbone ribs. The telescopic rod has an internal locking structure, such as a pin hole lock or a threaded lock, which can fix the position after adjustment to the target length, ensuring the stability of the second positioning space height. Operators can quickly complete height adjustments, shorten changeover time, and improve the continuity and flexibility of the processing flow. It is especially suitable for scenarios involving the alternating processing of multiple specifications of herringbone ribs, thus improving production efficiency.

[0040] The implementation process of a grid processing mold fixture according to an embodiment of this application is as follows: According to the processing requirements of the grille to be processed, the target curvature parameters (such as radius of curvature, arc length, etc.) that need to be adjusted for the arc worktable 1 are determined; use tools (such as wrenches) to loosen the first locking part 412 and the second locking part 422 of the adjustment components 4 on all support frames 2, so that the first threaded rod 41 and the second threaded rod 42 can move freely along the long waist hole, and release the fixed constraint on the arc worktable 1. First, level and fix the support frame 2. According to the target curvature, move the first threaded rod 41 and the second threaded rod 42 along the long waist hole. The first limiting cylinder 411 and the second limiting cylinder 421 push the arc-shaped worktable 1 to adjust the arc contour. During the process, a measuring tool (such as an arc ruler) can be used to measure the curvature of the worktable in real time until it meets the target curvature. After confirming that the curvature is correct, retighten the first locking part 412 and the second locking part 422 to lock the position of the threaded rods and ensure that the curvature of the arc-shaped worktable 1 is stable. According to the specifications of the main ribs and the ribs of the grid, select the appropriate jig 33 (if the positioning height of the ribs needs to be adjusted, the locking structure of the first upright 332 telescopic rod can be unlocked, stretched or compressed to the target length and then relocked). The first connector 311 of the first mounting plate 31 and the second connector 321 of the second mounting plate 32 pass through the first connecting hole 11 and the second connecting hole 12 of the arc-shaped workbench 1, respectively, and then the first fastener 312 and the second fastener 322 are tightened and fixed to complete the installation of the clamp assembly 3. The spacing of the clamp assembly 3 ensures that the welding heat deformation is evenly distributed. Place the bottom main ribs of the grid one by one into the V-shaped groove of the first positioning space of the frame 33, and place the top main ribs on the third crossbar 335, ensuring that the bottom of the main ribs fits the positioning groove 3311 of the first crossbar 331 and the top fits the positioning groove 3311 of the third crossbar 335. Confirm the axial position of the main ribs through the baffle 13. The prefabricated figure-eight ribs are placed into the second positioning space of the jig 33. The height is adjusted by the telescopic rod so that the figure-eight ribs fit precisely into the positioning space without shaking or shifting. Welding is then performed on the connection nodes between the main ribs and the figure-eight ribs according to the grid welding process requirements. If fine adjustments to the arc-shaped worktable 1 are needed, compensation can be made by adjusting the positions of the first threaded rod 41 and the second threaded rod 42. The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
