Description

Technical Field

[0001] This invention relates to the field of machining technology, specifically to a cross-wing riveting device. Background Technology

[0002] As the only moving component within the reactor core, the control rod cross fins are typically assembled using a process of "split positioning—clamping and fixing—point-by-point riveting." The mainstream solution involves using a combination of a general-purpose vise, a manual riveting machine, and a simple positioning fixture for riveting operations. The 2mm diameter rivets are crimped by manually adjusting the part's orientation and visually aligning them. This method has become a relatively mature operating procedure in conventional mechanical assembly. It usually utilizes rigid support plates, adjustable pads, and threaded clamping mechanisms to achieve basic constraints on the workpiece, and relies on the operator's experience to control the clamping force and riveting stroke to meet general precision requirements (such as flatness 0.5mm and parallelism 0.3mm).

[0003] However, for the control rod cross wing, a special component characterized by its ultra-long size (total length 1175mm), thin-walled irregular shape (four wings arranged in an orthogonal cross pattern, with a cladding plate thickness of only 0.5mm), high-density riveting (a single piece requires 224 rivets), and stringent geometric tolerances (flatness of the reference surface ≤0.2mm, parallelism and perpendicularity ≤0.1mm after riveting), existing general-purpose clamps and riveting methods struggle to simultaneously ensure assembly stability and geometric accuracy consistency. On the one hand, vise-type clamping devices cannot provide uniform and controllable clamping force without damaging the thin-walled cladding plate, resulting in the cross wing... The components are prone to slight displacement or elastic deformation during riveting. On the other hand, the lack of precise horizontal positioning and continuous transmission capability means that the alignment of rivet holes relies on repeated manual correction, which not only significantly reduces assembly efficiency but also makes it difficult to ensure that all 224 rivets simultaneously meet the geometric tolerance requirements specified in the drawings in different spatial orientations (including horizontal and vertical sides). In addition, since the internal cylindrical absorber (φ4.2mm) and the upper and lower support frames are clearance fit, the current clamping condition cannot effectively prevent axial slippage during assembly, further exacerbating the risk of riveting datum instability. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the purpose of this invention is to provide a cross-wing riveting device to solve the problems of low assembly efficiency caused by the ultra-long size and thin-walled irregular shape of the control rod cross wing during the riveting process, which makes it difficult to achieve high-density riveting and strict dimensional and positional tolerances; and the problems caused by the complex assembly process.

[0005] This invention is achieved using the following technical solution:

[0006] A cross-wing riveting device includes a horizontal worktable with two parallel guide rails. A clamping mechanism for clamping a cross-wing assembly is slidably connected above the guide rails via a slider. A riveting mechanism is fixedly installed on the horizontal worktable on one side of the guide rails.

[0007] The clamping mechanism includes a fixed plate, with clamping block one and clamping block two arranged opposite each other on the upper part of the fixed plate. Side pads are provided on the opposite surfaces of clamping block one and clamping block two, and an upper pad for receiving the cross wing assembly is provided on the upper part. The side pads are provided with contoured grooves, and the two side pads together form a contoured clamping space that matches the contour of the cross wing assembly. The clamping block one is also provided with a locking element for clamping the cross wing assembly.

[0008] The riveting mechanism includes a support frame, on which a guide rod is mounted. A lifting riveting component is slidably mounted on the guide rod, and a vertical drive component for driving its lifting and lowering is connected to one side of the lifting riveting component.

[0009] Furthermore, a limiter is connected to the slider to limit the relative position of the clamping mechanism on the guide rail. The limiter is a guide rail clamp.

[0010] Furthermore, the two ends of the wing plate of the cross wing assembly are respectively a first support frame and a second support frame; the clamping mechanism is provided in two sets, with a first clamping mechanism for clamping the first support frame and a second clamping mechanism for clamping the second support frame; the two clamping mechanisms cooperate with each other to clamp the cross wing assembly.

[0011] Furthermore, a reinforcing plate is provided between the inner side of the clamping block and the side pad to improve the clamping strength. Riveting operations generate large impact loads. The reinforcing plate installed at the side pad position can significantly improve the overall bending and torsional stiffness of the clamping mechanism; prevent the device from warping, denting, or deforming after long-term stress; and ensure that the clamping accuracy of the contour clamping space remains stable.

[0012] Furthermore, the locking component includes a clamping screw and a guide post passing through the clamping block one. The clamping screw presses against the reinforcing plate of the clamping block one to clamp the cross wing assembly. The guide post guides the stroke of the clamping screw, so that the clamping block one, clamping block two, and pad plate always maintain parallel and coaxial movement during the movement, without skew or offset, ensuring that the cross wing assembly is centered and the clamping gap on both sides is uniform.

[0013] Furthermore, the lifting riveting component includes a retaining sleeve, into which the guide rod is fitted and secured by a locking screw. The guide rod provides circumferential limiting and precise linear guidance for the lifting riveting component, restricting its rotation along with the vertical drive component and retaining only vertical freedom of movement. Ribs are installed on the side of the retaining sleeve, and a working groove for mounting the cross wing assembly is provided on the rib. A riveting punch is installed on the working groove to rivet the cross wing assembly.

[0014] Furthermore, the vertical drive component includes a rotating rod, the bottom end of which is fixed in a thrust ball bearing inserted into the support frame. The thrust ball bearing not only bears the large axial impact load generated during the riveting process, but also significantly reduces the end face friction resistance when the screw rotates, ensuring that the screw rotates easily and smoothly. The middle part of the rotating rod is threadedly connected to a ferrule. A rotating wheel is connected to the top of the rotating rod. By rotating the rotating wheel, the lifting riveting component is driven to move up and down along the guide rod axis, thereby adjusting the riveting height of the cross wing assembly.

[0015] The process of using this invention is as follows:

[0016] 1. Clamping and positioning: Place the cross wing assembly to be processed stably between the first clamping mechanism and the second clamping mechanism on the horizontal worktable; respectively embed the first support frame and the second support frame on both sides of the cross wing assembly wing plate into the contour clamping space of the first clamping mechanism and the contour clamping space of the second clamping mechanism; tighten the locking parts on the first clamping mechanism and the second clamping mechanism to clamp the cross wing assembly evenly in both directions.

[0017] 2. Single Riveting: Adjust the riveting mechanism position to perform the riveting operation. Manually rotate the wheel clockwise to drive the rotating rod, which in turn raises the riveting component vertically and smoothly downwards, allowing the covering plate portion of the cross-wing assembly to enter the working groove of the rib plate. At this point, the pre-installed riveting punch is aligned with the area to be riveted. Manually press down the riveting punch to contact the rivet, completing the riveting of the covering plate rivet at that position. After riveting is completed, rotate the wheel counterclockwise to raise the riveting component back to its original position.

[0018] 3. Horizontal Riveting: After a single riveting operation is completed, the sliding clamping mechanism adjusts the position to be riveted. Release the guide rail clamp, and with the help of the guide rail and slider, move the clamping mechanism and the cross-wing assembly to be processed horizontally left and right, moving the next set of rivets to the position directly below the lifting riveting component. Relock the guide rail clamp, and repeat the single riveting action to complete all horizontal riveting operations.

[0019] 4. Vertical riveting: For the vertical riveting requirements of the cross wing assembly, the vertical height of the stiffener plate can be flexibly adjusted by the cooperation of the guide rod and the lifting riveting part, so that the riveting punch can work at different vertical heights; repeat the above single riveting action to complete the riveting processing of different facade positions.

[0020] After all processes are completed, loosen the clamping screws on the clamping mechanism, remove the finished cross wing assembly, and the processing is complete.

[0021] Compared with the prior art, this application has at least the following beneficial effects:

[0022] This application solves the riveting problem in the vertical direction by constructing a double-guide-rail structure on a horizontal worktable, enabling the clamping mechanism to move horizontally; by constructing a liftable double-punch riveting mechanism; and by integrating these three elements into a single device, it fundamentally overcomes the bottleneck of general-purpose vises and manual riveting equipment in the riveting and assembly of ultra-long and irregularly shaped parts. Specifically:

[0023] First, the clamping mechanism adopts a left-right differentiated design and a 2mm contour adaptive groove. While providing uniform clamping force, it applies the constraint load completely to the upper and lower support frame bodies, completely avoiding local compression of the U-shaped covering plate, preventing the cylindrical absorber rod from slipping off due to the deformation of the covering plate, and ensuring the geometric stability of the initial riveting posture.

[0024] Secondly, the transmission structure composed of parallel double guide rails and sliders enables the 1175mm long cross wing assembly to achieve high-precision positioning in the horizontal plane, eliminating the cumulative error introduced by manual adjustment and providing a foundation for precise positioning of multiple rivets in all positions.

[0025] Third, the lifting and matching structure of the guide rod, drive component, and lifting riveting component, and the rotary wheel adjustment achieve precise matching of riveting height; the riveting punch is set in the working surface of the stiffener plate, which realizes the balanced application of riveting force and significantly suppresses the eccentric warping during the riveting process, so that the flatness of the final riveting surface is stably controlled within 0.2mm, and the parallelism and perpendicularity simultaneously meet the 0.1mm tolerance requirement.

Detailed Implementation

[0035] To better understand the above-mentioned objectives, features, and advantages of the present invention, the solutions of the present invention will be further described below. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of the invention, but the invention may also be practiced in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the invention, and not all embodiments.

[0037] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0038] The control rod cross fins are a crucial component of this type of equipment, and the only movable part in the reactor core. Their function is to compensate for reactivity changes from zero power to full power by moving up and down, utilizing the boron carbide-containing cylindrical absorber rods encased within the cross fins. This allows for hot shutdown and adjustment of transient reactivity changes. Under any operating condition, deformation of the control rod cross fins should not impede emergency reactor shutdown.

[0039] like Figure 1As shown, the cross-wing assembly 4 consists of a central cross-wing support 42 and four wing plates 41. The two ends of the wing plates 41 are a first support frame 411 and a second support frame 412, respectively. A covering plate 413 is riveted to the two support frames by rivets 414, and cylindrical absorber rods 43 are encased within the covering plate 413. Due to the large number of rivets 414 used, even if the four covering plates 413 are fixedly clamped to the first support frame 411 and the second support frame 412 respectively, the overall length of the cross-wing assembly 4 is too long to guarantee that the cylindrical absorber rods 43 inside the covering plate 413 will not fall out of the support frame, thus failing to guarantee the accuracy requirements of the reference plane formed by the upper and lower cross-wing frames after riveting.

[0040] Specifically: the cross-wing assembly 4 has a total length of 1175mm and a width of 200mm. The first support frame 411 is 194mm long and 200mm wide; the second support frame 412 is 37mm long and 200mm wide. A cylindrical absorber rod 43 is sandwiched between the two support frames. A covering plate 413 with a length of 822mm, a width of 91.5mm, and a thickness of 5.2mm is installed on the outside of the cylindrical absorber rod 43. Figure 2 As shown, the internal structure of the cross-wing assembly 4 is as follows: 20 cylindrical absorber rods 43 with a diameter of 4.2 mm are installed on each of the four wing edges of the cross-wing, covering a single-sided envelope of 3.1 mm. Each covering plate 43 has three edges that need to be riveted together: 40 rivets on the long side and 8 rivets on the short side, for a total of 224 rivets on the four sides. The flatness of the riveted surface with the reference surface must be within 0.2 mm, and the parallelism and perpendicularity must be within 0.1 mm.

[0041] Based on this, the present invention designs a cross-wing riveting device, which completes the riveting of multiple rivets through tooling fixtures, etc., to ensure that the riveting of the rivets is safe, reliable and does not deform, and meets the accuracy requirements of the riveting plane of the cross-wing assembly 4 after assembly.

[0042] refer to Figure 1-7 As shown, a cross-wing riveting device includes a horizontal worktable 1, on which two parallel guide rails 11 extending in the horizontal direction are provided. A clamping mechanism 2 for clamping a cross-wing assembly 4 is slidably connected above the guide rails 11 via a slider 21. A limiter is connected to the slider 21 to limit the relative position of the clamping mechanism 2 on the guide rails 11. A riveting mechanism 3 is fixedly provided on the horizontal worktable 1 on one side of the guide rails 11.

[0043] In this process, after clamping the cross wing assembly 4, the clamping mechanism 2 slides horizontally along the guide rail 11 to sequentially transmit rivets at different positions to the riveting mechanism 3 below. At the same time, the riveting mechanism 3 performs riveting on the plane of the covering plate 413 of the cross wing assembly 4 through vertical lifting and lowering, so as to complete the continuous riveting of all riveting points of the cross wing assembly 4 in a single clamping.

[0044] like Figure 3 As shown, the horizontal worktable 1 has an overall length of 2460mm, a width of 1210mm, and a height of 652mm. Two parallel linear guide rails 11 are fixed to its surface by M6 screws, allowing the clamping mechanism 2 to move horizontally on the worktable; at the same time, they provide an installation reference for the riveting mechanism 3.

[0045] Furthermore, the limit switch uses a guide rail clamp.

[0046] Furthermore, the clamping mechanism 2 is provided in two sets: a first clamping mechanism is provided for clamping the first support frame 411; and a second clamping mechanism is provided for clamping the second support frame 412; the two clamping mechanisms 2 cooperate with each other to clamp the cross wing assembly 4.

[0047] like Figure 5 As shown, the first clamping mechanism is composed of a fixed plate 21 (260×206×15mm), clamping block 1 23 and clamping block 24 (206×100×170mm), two side pads 26 (206×120×10mm), one reinforcing plate 25 (206×120×10mm), two upper pads 27 (206×100×10mm), and two guide posts 282 (10×153mm).

[0048] The fixed plate 21 has 16 Φ7mm through holes that mate with 16 M6 threaded holes on the guide rail slider 21, and are connected by M6×20 screws. Clamping block 1 23 and clamping block 24 each have 4 M10 threaded holes at their bottom that mate with 8 Φ11mm through holes on the fixed plate 21, and are connected by M10×30 screws. The two side pads 26 and two upper pads 27 each have 8 M6 threaded holes, and the side pad 26 also has 1 M20 threaded hole, which are connected to clamping block 1 23 or clamping block 24 by M6×20 screws and M20×120 screws, respectively. Each of the two side pads 26 and two upper pads 27 has a 2mm thick contoured groove to fit the contour of the first support frame 411 of the cross wing assembly 4. A reinforcing plate 25 is positioned between the inner surface of clamping block 1 23 and the side pads 26 to improve clamping strength. The clamping block 23 is also equipped with a clamping screw 281 and a guide post 282. The clamping screw 281 presses against the reinforcing plate 25 to clamp the cross wing assembly 4; the guide post 282 guides the stroke of the clamping screw 281.

[0049] like Figure 6 As shown, the second clamping mechanism is composed of a fixed plate 21 (260×58×15mm), clamping block 1 23 and clamping block 24 (50×100×170mm), two side pads 26 (50×120×10mm), one reinforcing plate 25 (50×120×10mm), two upper pads 27 (50×100×10mm), and two guide posts 282 (10×153mm).

[0050] The fixed plate 21 has eight Φ7mm through holes that mate with eight M6 threaded holes on the guide rail slider 21, and are connected by M6×20 screws. Clamping block 1 23 and clamping block 24 each have four M10 threaded holes at their bottoms that mate with eight Φ11mm through holes on the fixed plate 21, and are connected by M10×30 screws. The two side pads 26 and two upper pads 27 each have five M6 threaded holes, and the side pad 26 also has one M12 threaded hole, which are connected to clamping block 1 23 or clamping block 24 by M6×20 screws and M20×120 screws, respectively. Each of the two side pads 26 and two upper pads 27 has a 2mm thick contoured groove to fit the contour of the second support frame 412 of the cross wing assembly 4. A reinforcing plate 25 is positioned between the inner surface of clamping block 1 23 and the side pads 26 to improve clamping strength. The clamping block 23 is also equipped with a clamping screw 281 and a guide post 282. The clamping screw 281 presses against the reinforcing plate 25 to clamp the cross wing assembly 4; the guide post 282 guides the stroke of the clamping screw 281.

[0051] Furthermore, such as Figure 7 As shown, the riveting mechanism 3 includes a support frame 31, which is fixed to the horizontal worktable 1 by M12 screws. The top of the support frame 31 has a mounting hole, in which a guide rod 33 is installed and fixed by M12 screws; a lifting riveting component 34 is slidably mounted on the guide rod 33, and a vertical drive component 32 for driving its lifting and lowering is connected to one side of the lifting riveting component 34.

[0052] The lifting riveting component 34 includes a sleeve 341, into which a guide rod 33 is fitted and can be fixed by a locking screw; a stiffening plate 342 is installed on the side of the sleeve 341, and a working groove for placing the cross wing assembly 4 is opened on the stiffening plate 342, and a riveting punch 343 is installed on the working groove to rivet the cross wing assembly 4.

[0053] The vertical drive component 32 includes a rotating rod 321, which is an M20 screw. The bottom end of the rotating rod 321 is fixed in a thrust ball bearing inside the support frame 31. The middle part of the rotating rod 321 is threadedly connected to the ferrule 341. A rotating wheel 322 is connected to the top end of the rotating rod 321. By rotating the rotating wheel 322, the lifting riveting component 34 is driven to move up and down along the guide rod 33 axially, thereby adjusting the riveting height of the cross wing assembly 4.

[0054] refer to Figure 1-7 As shown, the process of using the cross-wing riveting device of the present invention is as follows:

[0055] Clamping and positioning: such as Figure 4As shown, the cross-wing assembly 4 to be processed is placed stably on the tooling positioning position of the horizontal worktable 1. The positions of the first clamping mechanism and the second clamping mechanism are adjusted, and the first support frame 411 and the second support frame 412 on both sides of the wing plate 41 of the cross-wing assembly 4 are respectively embedded into the corresponding contour clamping space; the clamping screws 281 on the first clamping mechanism and the second clamping mechanism are tightened to clamp the cross-wing assembly 4 evenly in both directions, ensuring that the workpiece does not move or deviate, and is completely centered and locked.

[0056] Single riveting: such as Figure 7 As shown, adjust the position of the riveting mechanism 3 to perform the riveting operation. Manually rotate the wheel 322 clockwise, driving the rotating rod 321 to move the lifting riveting component 34 vertically and smoothly downward, so that the covering plate 413 of the cross wing assembly 4 enters the working groove of the rib plate 342; at this time, the pre-installed riveting punch 343 is aligned with the part to be riveted, and the riveting punch 343 is manually pressed down to contact the rivet 414, applying uniform pressure to complete the riveting of the covering plate 413 and rivet 414 at this position. After the riveting is completed, rotate the wheel 322 counterclockwise to lift and reset the lifting riveting component 34.

[0057] Horizontal riveting: After a single riveting operation is completed, the sliding clamping mechanism 2 adjusts the position to be riveted. The guide rail clamp is released, and with the cooperation of the guide rail 11 and the slider 21, the clamping mechanism 2 and the cross-wing assembly 4 to be processed are moved horizontally left and right, moving the next set of rivets 414 to the position directly below the lifting riveting component 34. The guide rail clamp is then re-locked, and the above single riveting action is repeated to complete all horizontal riveting operations in sequence.

[0058] Vertical riveting: For the vertical riveting requirements of the cross wing assembly 4, the vertical height of the rib plate 342 can be flexibly adjusted by the cooperation of the guide rod 33 and the lifting riveting part 34, so that the riveting punch 343 can work at different vertical heights, repeat the above single riveting action, and complete the riveting processing of different facade positions.

[0059] After all processes are completed, loosen the clamping screw 281 on the clamping mechanism 2, remove the finished cross wing assembly 4, and the processing is complete.

[0060] The above description is merely a specific embodiment of the present invention, enabling those skilled in the art to understand or implement the present invention. Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments, and they should all be covered within the protection scope of the claims.
