[0002] In order to facilitate storage and transportation and save carrying space, current aerospace products often use split riveting assembly structures for folding and unfolding mechanisms. In the storage and transportation state, the product is in a folded state. In the working state, the product is quickly changed from the folded state to the unfolded state under the action of the folding and unfolding mechanism. Therefore, the reliability of the folding and unfolding mechanism has a significant impact on the performance of the product. With the continuous increase in the size and scale of the product, the number of key rotating mechanisms for connecting parts in the folding and unfolding mechanism also increases, which puts higher requirements on the riveting accuracy and motion coordination between the rotating mechanisms. At present, the manual riveting method is used to ensure the accuracy of such products, which has great difficulty in riveting assembly, low one-time qualification rate, and often needs to be adjusted and reworked multiple times, which cannot meet the design requirements and seriously affects the use effect of the product.

[0010] Optionally, a slot is arranged on the upper cushion block and corresponds to the mounting surface of the main body, the slot being penetrated in the direction towards the lower cushion block, so as to ensure that the riveting area of the connecting lug can be completely exposed, thereby facilitating the riveting operation.

[0011] Optionally, a support column is arranged on the lower cushion block and corresponds to the position of the profile of the auxiliary body close to the rotating shaft, the length of the support column being adjustable, so as to support the auxiliary body of the product, thereby controlling the auxiliary body of the product at the chord plane of the main body.

[0012] Optionally, the second cushion block set comprises an upper cushion block and a lower cushion block, the inner profile of the upper cushion block and the inner profile of the lower cushion block of the second cushion block set being adapted to the outer profiles of the two sides of the body of the main body and the outer profiles of the two sides of the auxiliary body respectively, so that the upper cushion block and the lower cushion block of the second cushion block set can play a supporting and constraining role on the body and the auxiliary body of the main body after being buckled.

[0013] Optionally, mounting holes are arranged on the corresponding positions of the upper cushion block and the lower cushion block, so as to fixedly connect the two through the fixing member.

[0022] (1) The present application innovatively designs a special riveting tool for the folding and unfolding mechanism with multiple rotating mechanisms, which has large structure size and high assembly precision. The riveting tool specifically includes a simulation joint, a cushion block group, a driving rod and a positioning piece. The simulation joint is used to fix the main body of the product to determine the relative position of the main body. The cushion block group is used to support and constrain the main body and the secondary body of the product. The driving rod is used to simulate the power element, and the secondary body is driven to rotate by rotating the driving rod to simulate the real motion state and analyze the motion condition. The simulation joint and the main body of the product are connected by the positioning piece to constrain the positions of the two.

Moreover, the riveted product mechanism is flexible in motion, has excellent assembly quality and use effect.

[0023] (2) The present application sets a support column on the lower cushion block at a position corresponding to the rotation shaft near the secondary body profile, and sets the length of the support column as adjustable, so as to support the secondary body of the product, thereby controlling the secondary body of the product at the chord plane of the main body.

[0024] (3) The present application sets a constraint bracket on the surface of the upper cushion block facing the lower cushion block, so as to limit the swing of the connecting lug in the angular direction, thereby preventing the swing amplitude of the secondary body of the product from being too large.

[0025] (4) The present application sets a slot on the upper cushion block corresponding to the mounting surface of the main body, so as to ensure that the riveting area of the connecting lug is completely exposed, thereby facilitating riveting operation.

[0026] (5) The riveting method of the present application is not to directly use the riveting tool to connect the main body and the secondary body of the product through the connecting lug at one time, but to first assemble the main body and the secondary body, ensure that the two rotate smoothly without jamming, then fix the connecting lug, punch a riveting hole on the connecting lug, and then confirm that the secondary body rotates smoothly relative to the main body without jamming before riveting the main body and the secondary body. The product obtained by the above riveting method has high first-time riveting yield (the first-time riveting yield is improved from 50% to more than 95%), shortens the production cycle, and provides an effective solution for the riveting and assembly process difficulty of similar folding products. Moreover, the riveted product mechanism is flexible in motion, has excellent assembly quality and use effect.

DETAILED DESCRIPTION

[0038] The preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings, which form a part of this application, and together with the embodiments of the present application serve to explain the principles of the present application, and are not intended to limit the scope of the present application.

[0039] Example 1

[0040] One specific embodiment of the present application discloses a riveting tool for riveting a folding and unfolding space product with multiple rotating mechanisms, which has large structure size and high assembly precision requirement.

[0041] As shown in Figure 1 , the folding and unfolding space product of the present application comprises a main body 1 and a sub-body 3. The main body 1 and the sub-body 3 are connected through a connecting lug 4.

[0042] The main body 1 comprises a head 18 and a body 19. The width of the head 18 is greater than the width of the body 19.

[0043] As shown in Figure 2 , the edge of one side of the head is provided with two grooves with openings facing the side surface, respectively. The connecting part of the two grooves forms a positioning assembly surface 20. The positioning assembly surface is provided with a pin hole 27 for the positioning member 12 to pass through.

[0044] Continuing to refer to Figure 2 , the head is further provided with a through hole 21 for the main rotating shaft to pass through. The through hole 21 penetrates along the length direction of the main body 1, which is used for subsequent trial rotation of the sub-body 3.

[0045] As shown in Figure 3 , the edge of one side of the head 18 of the main body 1 is provided with a mounting surface 22 for mounting the connecting lug 4. The edge of one side of the body 19 of the main body 1 is also provided with a mounting surface 22 for mounting the connecting lug 4. The upper surface and the lower surface of the mounting surface 22 are lower than the upper surface and the lower surface of the main body, and form a stepped surface with the upper surface and the lower surface of the main body. The mounting surface 22 is provided with a riveting hole for the riveting member 2 to pass through. The riveting hole penetrates along the thickness direction of the main body.

[0046] Specifically, there is one mounting surface 22 on the head of the main body, and there are three mounting surfaces 22 on the body of the main body.

[0047] The connecting lug 4 comprises a clamping end connected with the mounting surface 22 of the main body and a rotating shaft end 28 connected with the sub-body. As shown in Figure 1 , the top surface and the bottom surface of the clamping groove are provided with riveting holes for the riveting member 2 to pass through. Exemplarily, the number of riveting holes on the top surface and the bottom surface of the clamping groove is two, respectively, and the positions of the riveting holes on the top surface and the bottom surface correspond to each other.

[0048] In a preferred embodiment, the end of one of the two riveting holes on the top surface of the clamping groove is provided with a counterbore for accommodating the head of the riveting member 2, so as to prevent the head from protruding out of the outer surface of the main body.

[0049] The rotating shaft end of the connecting lug 4 is provided with a first rotating shaft hole 15, which penetrates along the thickness direction of the connecting lug 4.

[0050] The auxiliary body 3 has a slot (not shown in the figure) on the edge of the side where it connects to the main body 1 to accommodate the rotating end of the connecting lug 4. The connecting lug 4 and the auxiliary body are connected by a connecting shaft 6. A spherical bearing 7 is provided in the first rotating hole 15 of the connecting lug 4, and the spherical bearing 7 is sleeved on the connecting shaft 6.

[0051] In addition, a groove (not shown in the figure) is provided at the bottom of the edge of the side where the sub-body connects to the main body.

[0052] Specifically, there are multiple connecting ears and multiple connecting hinges. The connecting hinge closest to the head of the main body is the main hinge 5.

[0053] The following describes the riveting fixtures used to achieve the aforementioned folding and unfolding aerospace products.

[0054] like Figure 4 As shown, the riveting fixture in this embodiment includes a simulated joint 8, a pad assembly, a drive rod 13, and a positioning component 12.

[0055] The simulated connector 8 is used to fix the main body 1 of the folding and unfolding aerospace product in order to determine the relative position of the main body.

[0056] The pad block assembly is used to support and constrain the main body 1 and sub-body 3 of foldable and deployable aerospace products.

[0057] The drive rod 13 is used to simulate a power element. One end of the drive rod is a handle, and the other end is connected to the main rotating shaft 5 fixed on the sub-body 3. Taking the second rotating shaft hole 23 on the simulated connector 8 as the base point, the drive rod 13 is rotated to drive the sub-body 3 to rotate, thereby simulating the real motion state and analyzing the motion.

[0058] The simulated connector 8 and the main body 1 of the folding and unfolding aerospace product are connected by a positioning element 12 to constrain their positions. For example, the positioning element 12 is a positioning pin.

[0059] like Figure 4 As shown, the simulated connector 8 includes a wider first end 24 and a narrower second end 25, meaning that the simulated connector is wide at one end and narrow at the other.

[0060] The first end 24 of the simulated connector is provided with a mounting groove 26 with an opening facing the main body 1. The mounting groove 26 is used to place the positioning assembly surface 20 on the main body of the foldable and unfoldable aerospace product.

[0061] To facilitate the placement of the positioning assembly surface 20 on the main body, the mounting groove extends along the length of the simulated joint.

[0062] In one possible implementation, the top and bottom surfaces of the mounting groove 26 are parallel to the mounting groove, serving as reference surfaces for subsequent riveting. Pin holes for the positioning member 12 to pass through are provided at corresponding positions on the top and bottom surfaces of the mounting groove 26.

[0063] Specifically, the number of pin holes varies according to the length of the positioning assembly surface 20. In this embodiment, the number of pin holes is 3.

[0064] As shown in Figure 3 , the second end 25 of the simulation joint is provided with a second rotation shaft hole 23, and the driving rod 13 passes through the second rotation shaft hole 23 to drive the sub-body 3 of the folded and unfolded space product to rotate.

[0065] As shown in Figure 4 , the cushion block group includes a first cushion block group and a second cushion block group. The first cushion block group is used to support and constrain the head 18 of the main body 1 and the sub-body 3 in the width direction, and the second cushion block group is used to support and constrain the body 19 of the main body 1 and the sub-body 3 in the width direction.

[0066] The first cushion block group includes an upper cushion block 9 and a lower cushion block 11. The inner profile surface of the upper cushion block 9 and the inner profile surface of the lower cushion block 11 are respectively adapted to the outer profile surfaces of the two sides of the head 18 of the main body 1 and the two sides of the sub-body 3, so that the upper cushion block 9 and the lower cushion block 11 can play a supporting and constraining role on the head of the main body and the sub-body after being buckled.

[0067] As shown in Figure 4 , in a preferred embodiment, the upper cushion block 9 is provided with a slot 14 corresponding to the mounting surface 22 of the main body 1, and the slot penetrates in the direction towards the lower cushion block 11, so as to ensure that the riveting area of the connecting lug 4 can be completely exposed, thereby facilitating the riveting operation. The lower cushion block 11 is provided with a support column 17 at a position corresponding to the type surface of the sub-body close to the connecting rotation shaft. The length of the support column 17 can be adjusted to support the sub-body 3 of the product, so as to control the sub-body 3 of the product at the chord plane of the main body 1.

[0068] Further, the corresponding positions of the upper cushion block and the lower cushion block are provided with mounting holes, so as to be fixedly connected by the screws 10.

[0069] Continuing to refer to Figure 4 , the upper cushion block is provided with a constraint bracket 16 on the surface thereof facing the lower cushion block, which is used to limit the swing of the connecting lug 4 in the angular direction, so as to prevent the swing amplitude of the sub-body 3 of the product from being too large. The constraint bracket 16 is provided with a limiting slot, and the inner surface of the limiting slot is arc-shaped.

[0070] As shown in Figure 4 , the second cushion block group is similar to the first cushion block group in structure, except that the inner profile surface of the upper cushion block 9 and the inner profile surface of the lower cushion block 11 of the second cushion block group are respectively adapted to the outer profile surfaces of the two sides of the body 19 of the main body 1 and the two sides of the sub-body 3, so that the upper cushion block 9 and the lower cushion block 11 can play a supporting and constraining role on the body of the main body and the sub-body after being buckled.

[0071] Example Two

[0072] Another embodiment of the present application discloses a riveting method for folding and unfolding aerospace products, which can achieve high-precision riveting of rotating mechanisms. The riveting method of this embodiment is not to directly use a riveting tool to connect the main body and the secondary body of the product through the connecting lug once, but to first assemble the main body and the secondary body, ensure smooth rotation and no jamming between them, then drill riveting holes on the mounting surface of the connecting lug and the main body, and use a riveting piece to rivet and fix the main body and the secondary body. The one-time qualification rate of the product obtained by the above-mentioned riveting method is high (the one-time qualification rate is increased from 50% to more than 95%), the production cycle is shortened, and an effective solution is provided for the riveting and assembly process difficulty of similar folding products. Moreover, the mechanism of the riveted product moves flexibly, has excellent assembly quality and use effect.

[0073] The riveting method of this embodiment is completed by using the riveting tool of example one, mainly including two parts, which are: assembling the main body and the secondary body (including the first to sixth steps below), and ensuring smooth rotation and no jamming between the main body and the secondary body, then drilling riveting holes on the mounting surface of the connecting lug and the main body, and using a riveting piece to rivet and fix the main body and the secondary body (including the seventh to thirteenth steps below). Specifically, the steps include:

[0074] First, the simulation joint 8 is assembled with the main body 1 of the product as a whole.

[0075] As shown in Figure 3 , first, the simulation joint 8 is installed at the positioning assembly surface 20 on the main body, the relative position between the simulation joint and the main body is adjusted to align the three positioning holes thereon, and then three positioning pieces are used to fix the simulation joint 8 with the main body 1.

[0076] Second, the simulation joint 8 is placed parallel to the platform, at this time the folding and unfolding product is in a horizontal placement state, the simulation joint 8 is appropriately raised at the bottom, the distance between the product and the platform is controlled between 100mm-150mm, and after the distance is adjusted appropriately, the simulation joint is firmly fixed on the platform.

[0077] Third, the symmetry of the four mounting surfaces on the main body of the product for connecting the connecting lug 4 relative to the neutral surface of the simulation joint mounting groove is measured by using a dial indicator, and the symmetry needs to be controlled within 0.03mm. If the symmetry exceeds 0.03mm, it needs to be adjusted by the way of benchwork filing or gasket adjustment.

[0078] Fourth, as shown in Figure 5As shown, insert the four connecting ears into the four connecting ear mounting surfaces 22 on the main body 1 of the product. Use gauge blocks to adjust the gap between the connecting ears 4 and the side of the mounting surface 22 to ensure that the connecting ears are centered relative to the mounting surface and do not swing at an angle.

[0079] Fifth, use a dial indicator to measure the symmetry of the first pivot hole on each of the four connecting lugs relative to the simulated connector mounting slot 26. The symmetry must be controlled within 0.03mm. If the symmetry exceeds 0.03mm, it needs to be adjusted by filing the mounting surface of the connecting lugs or by adjusting the shims to ensure that the pivot hole of the connecting lug is located on the chord plane of the main body.

[0080] Sixth, such as Figure 6 As shown, remove the four connecting lugs from the main body, and then install them together with the main shaft, joint bearing, and connecting shaft onto the product sub-body. Then, install the connecting lugs together with the product sub-body onto the main body. Adjust the position of each connecting lug using the constraint bracket, and use gauge blocks to adjust the gap between the connecting lugs and the side of the main body mounting surface to ensure that the connecting lugs are centered relative to the mounting surface and do not swing at an angle.

[0081] Seventh, use gauge blocks or feeler gauges to roughly adjust the gap between the mating surfaces of the sub-body and the main body, ensuring that the gap is uniform at about 1.5mm. At this point, insert the drive rod through the second rotating hole on the simulation connector into the sub-body and connect it to the main rotating shaft fixed on the sub-body. If the drive rod cannot be inserted into the sub-body, the mating gap between the sub-body and the main body needs to be adjusted until the drive rod can be inserted smoothly.

[0082] Eighth, rotate the drive rod to make the sub-body rotate relative to the main body. Further fine-tune the position of the connecting lug or the meshing gap between the main body and the sub-body according to the rotation flexibility and jamming. The adjustment amount should be controlled within 0.3mm. After adjustment, use a force gauge to measure the rotational resistance torque of the sub-body relative to the main body. The resistance torque should be controlled within 1N·m.

[0083] Ninth, use tape to fix the constraint bracket and gauge block to the sub-body to prevent movement; remove the gauge block between the connecting lug and the main body mounting surface, and fill the gap between them with 502 glue 29. Note that glue 29 should not drip into the joint bearing. Fill the 4 connecting lugs with glue in sequence until the glue is completely cured.

[0084] Tenth, place the four lower pads on the platform, loosen the simulation connector, and place the main body, sub-body, and simulation connector together on the four lower pads. Then install the four upper pads, adjust the position of each pad so that the riveting area of ​​the connecting lug is fully exposed in the slotted area of ​​the upper pad. Tighten the upper and lower pads with screws, and adjust the support column on the lower pad to press the sub-body against the main body to control the sub-body at the chord plane of the main body and prevent the sub-body from rotating.

[0085] Eleventh, draw riveting hole position line on the connecting lug, each connecting lug contains 2 riveting holes, riveting holes are drilled through the mounting surface of the connecting lug and the main body, and countersunk holes are provided. The countersunk hole is used to accommodate the nail head of the riveting part to prevent the nail head from protruding from the outer surface of the main body. The countersunk hole adopts a positive and negative way, and there are 4 places on the positive and negative surfaces.

[0086] Twelfth, loosen the support column on the lower pad, remove the adhesive tape and restraint bracket fixed on the secondary body, and check again the rotation of the secondary body relative to the main body to ensure smooth rotation of the secondary body without jamming, and then tighten the support column.

[0087] Thirteenth, rivet the connecting lug on the main body using a rivet. When riveting, adopt a positive and negative way according to the countersunk hole (the riveting directions of the two riveting parts are opposite, i.e. one riveting part is riveted from top to bottom, and the other riveting part is riveted from bottom to top), so that both sides are uniformly stressed, avoiding deformation of single side stress leading to abnormal rotation of the secondary body. The nail head after riveting is not allowed to exceed the top surface of the simulation joint. The schematic diagram of the product and the riveting tool after assembly is shown in Figure 7 .

[0088] Fourteenth, after riveting, remove all the pads and check that the gap between the main body and the secondary body should be controlled within 1.5±0.3mm; rotate the drive rod to drive the secondary body relative to the main body, check the rotation flexibility and jamming, and measure the rotation resistance torque of the secondary body relative to the main body again, which should be controlled within 1N·m.

[0089] Fifteenth, remove the drive rod, remove the three positioning parts that fix the simulation joint, and remove the simulation joint from the main body. Clean the glue and other excess materials around the connecting lug to ensure the product is clean. At this point, the riveting assembly of the product is completed.

[0090] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or replacements within the technical range disclosed by the present application can be easily thought of by those skilled in the art, which should be covered within the protection scope of the present application.
