Description

Technical Field

[0001] This utility model relates to the field of fairing assembly technology, and in particular to a tensioning device and frame for fairing docking. Background Technology

[0002] A fairing is a protective outer shell designed for aircraft (such as satellites). As the name suggests, "fairing" refers to guiding airflow smoothly through optimized aerodynamic shape, while "fairing" emphasizes its enveloping protective characteristics. When an aircraft breaks through the atmosphere or travels at high speed, the streamlined surface of the fairing can convert oncoming air resistance into laminar flow, thereby ensuring precise control of the flight trajectory. At the same time, the fairing's robust outer shell constitutes a protective system, which can intercept potential threats such as space debris, providing a safe and stable working environment for the precision instruments inside the aircraft.

[0003] When fairings are manufactured, they are typically made up of two fairing halves, which require subsequent assembly (dating) using jigs. During fairing assembly, the two fairing halves are placed into two jigs respectively, and the jigs are then joined together to complete the fairing assembly. Generally, during the assembly process, the fairing is placed horizontally within the jig, and the assembly is performed using a horizontal assembly method (i.e., the two jigs are horizontally joined). For large-diameter fairings (such as satellite fairings), due to their larger size, a vertical assembly method is often used. This involves placing the two fairing halves into two jigs, then vertically hoisting the jigs to complete the fairing assembly.

[0004] When two jigs are joined (i.e., after the fairings are joined inside the jigs), if the joint between the two jigs is not securely tightened, that is, if the joint between the two fairing halves is not securely tightened, then when welding the joint between the two fairing halves after the fairings are joined together (i.e., when welding the two fairing halves into one piece), gaps will appear between the two fairing halves that are not securely tightened, thus making it impossible to smoothly carry out the welding work between the two fairing halves.

[0005] Therefore, there is an urgent need for a device that can firmly tighten the two frames after the fairings are joined, that is, a device that can firmly tighten the joint of the two fairing halves so that the welding work of the two fairing halves can be carried out smoothly.

[0052] For those skilled in the art, this invention can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the invention by illustrating examples.

[0053] For ease of description, the description in this embodiment may include terms such as "this device". Those skilled in the art should understand that "this device" refers to a tensioning device for fairing docking provided by this utility model.

[0054] Unless otherwise specified, all components of this device are made of metals known in the art, such as stainless steel, and are not specifically limited herein.

[0055] In one embodiment of this utility model, reference is made to Figure 12 The mold 17 is divided into two parts. During the fairing (not shown in the figure) assembly (docking) operation, the half-covers of the two fairings are respectively placed into the two mold 17s, and the merging of the two mold 17s realizes the assembly (docking) of the two fairing half-covers, thereby realizing the fairing assembly (docking) operation. The above content is all prior art known to those skilled in the art, and will not be elaborated here.

[0056] In one embodiment of this utility model, reference is made to Figure 12 and Figure 13 This device can be installed on two frames 17 respectively along the height direction of the frame 17, that is, each frame 17 will have one along its length direction (i.e., as shown in the image). Figure 12 Several of these devices are mounted on the frame 17 (in the vertical direction when placed vertically). The number of these devices mounted on the frame 17 is not particularly limited, and those skilled in the art can adjust the number of these devices mounted on the frame 17 according to the actual situation.

[0057] Reference Figure 1-13 In a first aspect, this utility model provides a tensioning device for fairing docking, the device comprising at least a vertical adjusting block 3, a horizontal adjusting block 9, and a tensioning rod 1, wherein:

[0058] On the tension rod 1 (i.e., on its outer surface along its axial direction), a left-hand external thread (not shown in the figure) and a right-hand external thread (not shown in the figure) are symmetrically arranged at the center position along the length direction of the tension rod 1. That is, in this embodiment, referring to... Figure 1-4 The tension rod 1 is a cylindrical external thread rod, and the thread on the tension rod 1 is symmetrical about the center position of the tension rod 1 along its length and is arranged on the outer surface of the tension rod 1 in the opposite direction of rotation.

[0059] According to one embodiment of the present invention, referring to... Figure 12 and Figure 13Vertical adjusting block 3 and horizontal adjusting block 9 are respectively installed at the joint of the two mold frames 17, and the vertical adjusting block 3 and horizontal adjusting block 9 are correspondingly arranged, that is, the vertical adjusting block 3 and horizontal adjusting block 9 are arranged correspondingly at the joint of the two mold frames 17. Preferably, the vertical adjusting block 3 and horizontal adjusting block 9 can be located at the same height (i.e., located at...). Figure 13 At the same height on the two frames 17 in the middle).

[0060] In this embodiment, refer to Figure 1-3 , Figure 5 and Figure 6 Both the vertical adjustment block 3 and the horizontal adjustment block 9 can be cuboid structures.

[0061] In this embodiment, the vertical adjustment block 3 and the horizontal adjustment block 9 can be connected to the joints of the two frames 17 respectively by means known in the art, such as by using bolts. No particular limitation is made here.

[0062] According to one embodiment of the present invention, referring to Figure 1-3 The vertical adjustment block 3 is equipped with a vertical adjustment mechanism, and the horizontal adjustment block 9 is equipped with a horizontal adjustment mechanism. Both the vertical and horizontal adjustment mechanisms are designed to accommodate the relative positions of the joints when the two frames 17 are not perfectly symmetrically joined, so that the two frames 17 can be smoothly joined along the length of the tension rod 1. (Refer to...) Figure 1-3 One end of the tension rod 1 is used to engage with the threaded horizontal adjustment mechanism, and the other end of the tension rod 1 is used to engage with the threaded vertical adjustment mechanism.

[0063] In one embodiment of this utility model, in reality, the probability of the two frames 17 being in a completely symmetrical docking state during the actual docking process is relatively low. That is, the two frames 17 are often in a partially symmetrical docking state during the docking process, meaning that there will be a slight misalignment at the interface of the two frames 17. In this case, if the vertical adjustment mechanism and the horizontal adjustment mechanism are not adjusted to adapt to the relative position of the docking point when the two frames 17 are not completely symmetrically docked, the two ends of the tensioning rod 1 cannot be threaded into the horizontal adjustment mechanism and the vertical adjustment mechanism respectively, that is, the tensioning work of the two frames 17 cannot be performed normally. By setting up vertical and horizontal adjustment mechanisms, the vertical and horizontal adjustment mechanisms can be adjusted in real time according to the slight misalignment that occurs at the interface of the two frames 17. This allows the vertical and horizontal adjustment mechanisms to adapt to the slight misalignment in the vertical and horizontal directions at the interface of the two frames 17, respectively. As a result, the two ends of the tensioning rod 1 can be threaded into the horizontal and vertical adjustment mechanisms, respectively, ensuring the normal operation of the tensioning of the two frames 17. In one embodiment of this utility model, since left-handed external threads and right-handed external threads are symmetrically arranged at the center position of the tensioning rod 1, and the two ends of the tensioning rod 1 are respectively connected to the horizontal adjustment mechanism and the vertical adjustment mechanism, when it is necessary to tighten the two frames 17, the tensioning rod 1 is rotated. In this case, the horizontal adjustment mechanism and the vertical adjustment mechanism will move towards each other, thereby driving the two frames 17 to move towards each other, thus achieving the tightening of the two frames 17, that is, achieving the firm tightening of the two fairing half-covers, thereby ensuring the smooth progress of the welding work of the two fairing half-covers.

[0064] Furthermore, since the two ends of the tension rod 1 are threaded into the horizontal adjustment mechanism and the vertical adjustment mechanism respectively, the two ends of the tension rod 1 will self-lock with the horizontal adjustment mechanism and the vertical adjustment mechanism respectively. In other words, it is equivalent to the "lead screw and slider" structure known in the art. For example, the rotation of the lead screw (i.e., equivalent to the tension rod 1 in this device) will drive the slider (i.e., equivalent to the horizontal adjustment mechanism and the vertical adjustment mechanism in this device) to move along the length of the lead screw, while the movement of the slider cannot drive the lead screw to rotate, thereby generating self-locking. Therefore, by setting up the tension rod 1, the horizontal adjustment mechanism and the vertical adjustment mechanism, the firmness of the tensioning of the two frames 17 can be better guaranteed, further ensuring the smooth progress of the welding work of the two fairing half-covers.

[0065] According to one embodiment of the present invention, referring to Figure 5 The vertical adjustment mechanism includes at least the following components along the vertical direction (i.e., along...). Figure 1Vertical adjustment through hole 4 is provided on vertical adjustment block 3 (vertical direction). (Refer to...) Figure 1 A vertical slider 7 is slidably installed inside the vertical adjustment through hole 4, and the end of the tension rod 1 near the vertical slider 7 (i.e. Figure 1 The left end of the tension rod 1 is used to engage with the vertical slider 7 via a thread.

[0066] In this embodiment, refer to Figure 5 The shape of the vertical adjustment through hole 4 can be a cuboid structure.

[0067] In this embodiment, refer to Figure 1 and Figure 7 The vertical slider 7 can be an I-shaped structure. The web of the vertical slider 7 can be slidably connected to the inner wall of the vertical adjustment through hole 4, and the flange of the vertical slider 7 can be slidably connected to the outer wall of the vertical adjustment block 3, thereby realizing the limiting sliding connection between the vertical slider 7 and the vertical adjustment block 3.

[0068] In this embodiment, refer to Figure 7 The vertical slider 7 is along the horizontal direction (i.e., along) Figure 7 A vertical slider tensioning hole 701 is provided on the vertical slider 7 in the horizontal direction. The inner wall of the vertical slider tensioning hole 701 is provided with an internal thread. The tensioning rod 1 is located at one end near the vertical slider 7 (i.e., Figure 1 The left end of the tension rod 1 can be threaded into the tension hole 701 of the vertical slider, thereby achieving the threaded engagement between the tension rod 1 and the vertical slider 7.

[0069] Preferably, the vertical slider tensioning hole 701 is a through hole structure, that is, the vertical slider tensioning hole 701 completely penetrates the vertical slider 7.

[0070] According to one embodiment of this utility model, the vertical adjustment mechanism further includes a vertical fixing part disposed on the vertical adjustment block 3. The vertical fixing part is configured to fix the position of the vertical slider 7 within the vertical adjustment through hole 4 to accommodate the vertical relative position when the frame 17 is not completely symmetrically connected. That is, after the vertical slider 7 is adjusted within the vertical adjustment through hole 4 according to the slight misalignment of the frame 17 in the vertical direction, the vertical fixing part can fix the position of the vertical slider 7 within the vertical adjustment through hole 4 at this time, thereby completing the adjustment work of the vertical adjustment mechanism.

[0071] Specifically, refer to Figure 1 and Figure 5 The vertical fixing part includes a detachable component mounted on the vertical adjusting block 3. The detachable component has a vertical adjusting oblong hole 6, the length direction of which is parallel to the length direction of the vertical adjusting through hole 4. (Refer to...) Figure 7The vertical slider 7 has a vertical slider fixing hole 702, which corresponds to the vertical adjustment elongated hole 6 (that is, when the vertical slider 7 moves within the vertical adjustment through hole 4, the vertical slider fixing hole 702 is always connected to the vertical adjustment elongated hole 6), and the vertical slider fixing hole 702 has an internal thread. (Refer to...) Figure 1 and Figure 2 A vertical adjustment fixing bolt 8 is slidably installed inside the oblong hole 6 for vertical adjustment (refer to...). Figure 10 The threaded rod of the vertical adjustment fixing bolt 8 is configured to be threadedly connected to the vertical slider fixing hole 702. When the threaded rod of the vertical adjustment fixing bolt 8 is threadedly connected to the vertical slider fixing hole 702, the bolt head of the vertical adjustment fixing bolt 8 can abut against the outer wall of the vertical adjustment block 3, thereby fixing the position of the vertical slider 7 in the vertical adjustment through hole 4.

[0072] In this embodiment, refer to Figure 1 , Figure 7 and Figure 13 The vertical slider fixing hole 702 can be formed at the end of the web of the vertical slider 7 away from the frame 17. Since the vertical slider fixing hole 702 corresponds to the vertical adjusting elongated hole 6, therefore, referring to... Figure 5 The vertical adjustment oval elongated hole 6 is also located at the end away from the frame 17.

[0073] According to one embodiment of the present invention, referring to... Figure 1 , Figure 2 and Figure 5 The aforementioned detachable component is the first baffle 5, and the end of the vertical adjustment block 3 away from the frame 17 is an open structure. The first baffle 5 can be detachably installed at the open structure of the vertical adjustment block 3, thus it can be seen that the vertical adjustment oval hole 6 is opened on the first baffle 5.

[0074] In this embodiment, refer to Figure 5 The first baffle 5 can be a U-shaped structure, and the first baffle 5 can be detachably connected to the vertical adjustment block 3 by means known in the art, such as by using bolts, without any particular limitation.

[0075] In one embodiment of this utility model, the vertical slider 7 can be easily installed or removed in the vertical adjustment through hole 4 by means of the first baffle 5.

[0076] According to one embodiment of the present invention, referring to... Figure 6 The horizontal adjustment mechanism includes at least the following components along the horizontal direction (i.e., along...). Figure 1 A horizontal adjustment through hole 10 is provided on the horizontal adjustment block 9 (in the horizontal direction). (Refer to...) Figure 1A horizontal slider 13 is slidably mounted inside the horizontal adjustment through hole 10, and the end of the tension rod 1 near the horizontal slider 13 (i.e. Figure 1 The right end of the tension rod 1 is used to engage with the horizontal slider 13 via a thread.

[0077] In this embodiment, refer to Figure 6 The horizontal adjustment through hole 10 can be a cuboid structure.

[0078] In this embodiment, refer to Figure 1 and Figure 8 The horizontal slider 13 can be an I-shaped structure. The web of the horizontal slider 13 can be slidably connected to the inner wall of the horizontal adjustment through hole 10, and the flange of the horizontal slider 13 can be slidably connected to the outer wall of the horizontal adjustment block 9, thereby realizing the limiting sliding connection between the horizontal slider 13 and the horizontal adjustment block 9.

[0079] In this embodiment, refer to Figure 8 The horizontal slider 13 along the horizontal direction (i.e., along Figure 8 A horizontal slider tensioning hole 1301 is provided on the horizontal slider 13 (in the horizontal direction), and an internal thread is provided on the inner wall of the horizontal slider tensioning hole 1301. The tensioning rod 1 is located at one end near the horizontal slider 13 (i.e., Figure 1 The right end of the tension rod 1 can be threaded into the tension hole 1301 of the horizontal slider, thereby realizing the threaded engagement between the tension rod 1 and the horizontal slider 13.

[0080] Preferably, the horizontal slider tensioning hole 1301 is a through hole structure, that is, the horizontal slider tensioning hole 1301 completely penetrates the horizontal slider 13.

[0081] According to one embodiment of the present invention, the horizontal adjustment mechanism further includes a horizontal fixing part disposed on the horizontal adjustment block 9. The horizontal fixing part is configured to fix the position of the horizontal slider 13 within the horizontal adjustment through hole 10 to accommodate the horizontal relative position when the frame 17 is not completely symmetrically aligned. That is, after the horizontal slider 13 is adjusted within the horizontal adjustment through hole 10 according to a slight misalignment of the frame 17 in the horizontal direction, the horizontal fixing part can fix the position of the horizontal slider 13 within the horizontal adjustment through hole 10 at this time, thereby completing the adjustment work of the horizontal adjustment mechanism.

[0082] Specifically, refer to 1 or Figure 6 The horizontal fixing part includes a horizontal adjustment oblong hole 12 formed on the horizontal adjustment block 9, and the length direction of the horizontal adjustment oblong hole 12 is parallel to the length direction of the horizontal adjustment through hole 10. (Refer to...) Figure 8The horizontal slider 13 is provided with a horizontal slider fixing hole 1302, which is correspondingly set with the horizontal adjustment elongated hole 12 (that is, when the horizontal slider 13 moves in the horizontal adjustment through hole 10, the horizontal slider fixing hole 1302 is always connected to the horizontal adjustment elongated hole 12), and the horizontal slider fixing hole 1302 is provided with an internal thread.

[0083] Preferably, refer to Figure 8 The horizontal slider fixing hole 1302 can be formed at the top of the web of the horizontal slider 13. Since the horizontal slider fixing hole 1302 corresponds to the horizontal adjustment elongated hole 12, therefore, referring to... Figure 6 The horizontal adjustment oval elongated hole 12 is opened at the top of the horizontal adjustment block 9.

[0084] Reference Figure 1 and Figure 2 A horizontal adjustment fixing bolt 14 is slidably installed inside the horizontal adjustment oblong hole 12 (see reference). Figure 11 The threaded rod of the horizontal adjusting fixing bolt 14 is configured to be threadedly connected to the horizontal slider fixing hole 1302. When the threaded rod of the horizontal adjusting fixing bolt 14 is threadedly connected to the horizontal slider fixing hole 1302, the bolt head of the horizontal adjusting fixing bolt 14 can abut against the outer wall of the horizontal adjusting block 9, thereby fixing the position of the horizontal slider 13 in the horizontal adjusting through hole 10.

[0085] According to one embodiment of the present invention, referring to reference 1, Figure 2 and Figure 6 The end of the horizontal adjusting block 9 away from the frame 17 is an open structure, and a second baffle 11 can be detachably installed at the open structure of the horizontal adjusting block 9.

[0086] In this embodiment, refer to Figure 6 The second baffle 11 can be a U-shaped structure, and the second baffle 11 can be detachably connected to the horizontal adjustment block 9 by means known in the art, such as by using bolts, without any particular limitation.

[0087] In one embodiment of this utility model, the horizontal slider 13 can be easily installed or removed in the horizontal adjustment through hole 10 by means of the second baffle 11.

[0089] In this embodiment, refer to Figure 1-4The rotating block 2 can be a hexagonal prism, and the width of the rotating block 2 is greater than the width of the tension rod 1, but the length of the rotating block 2 is much smaller than the length of the tension rod 1. The rotating block 2 can be coaxially arranged with the tension rod 1.

[0090] In one embodiment of this utility model, the rotating block 2 makes it easier to tighten the tensioning rod 1, thereby facilitating the tightening of the two frames 17. For example, a wrench known in the art can be used to contact and tighten the rotating block 2.

[0091] According to one embodiment of the present invention, referring to... Figure 1 The two ends of tension rod 1 (i.e. Figure 1 The two ends of the tension rod 1 protrude from the vertical slider 7 and the horizontal slider 13 respectively, and both ends of the tension rod 1 are threaded with limit nuts 18. The limit nuts 18 near the vertical slider 7 (i.e., Figure 1 The limiting nut 18 on the left side is used to connect with the end of the vertical slider 7 away from the rotating block 2 (i.e. Figure 1 The left end of the vertical slider 7 abuts against the horizontal slider 13. The limiting nut 18 (i.e., the one near the horizontal slider 13) is also abutted against. Figure 1 The limiting nut 18 on the right side is used to connect with the end of the horizontal slider 13 away from the rotating block 2 (i.e., Figure 1 The right end of the horizontal slider 13 abuts.

[0092] In this embodiment, the limiting nut 18 can be any nut known in the art that is suitable for this device, and no particular limitation is made here.

[0093] In one embodiment of this utility model, the limiting nut 18 can better ensure the tension of the two mold frames 17. For example, when the tension rod 1 slips in the vertical slider 7 or the horizontal slider 13, the limiting nut 18 can limit the tension rod 1, thereby maintaining the tension of the two mold frames 17 and preventing loosening.

[0094] According to one embodiment of the present invention, referring to... Figure 13 A second mounting plate 16 is installed at the joint of the two frames 17. (Refer to...) Figure 1 Both the vertical adjusting block 3 and the horizontal adjusting block 9 are equipped with a first mounting plate 15 at one end near the frame 17. The first mounting plate 15 is connected to the second mounting plate 16 by bolts, as is known in the art, so as to realize the connection between the vertical adjusting block 3 and the frame 17 and the horizontal adjusting block 9 and the frame 17, respectively.

[0095] In this embodiment, refer to Figure 1 and Figure 9 Both the first mounting plate 15 and the second mounting plate 16 can be flat cuboid structures.

[0096] In one embodiment of this utility model, the first mounting plate 15 and the second mounting plate 16 can make the vertical adjustment block 3 and the horizontal adjustment block 9 more firmly connected to the frame 17.

[0097] The second aspect of this utility model, with reference to... Figure 12 and Figure 13 Furthermore, a frame is provided that includes the aforementioned tensioning device for fairing docking. Those skilled in the art should understand that any frame using this device, i.e., the tensioning device for fairing docking provided by this utility model, is within the protection scope of this utility model.

[0098] Furthermore, although the above description explains that when the two frames 17 are not completely symmetrically connected during docking, the vertical fixing part and the horizontal fixing part can adapt to the vertical or horizontal relative position of the docking point when the two frames 17 are not completely symmetrically connected, those skilled in the art should understand that when the two frames 17 are completely symmetrically connected during docking, the vertical fixing part and the horizontal fixing part can also adapt to the vertical or horizontal relative position of the docking point when the two frames 17 are completely symmetrically connected, that is, no adjustment of the vertical adjustment mechanism and the horizontal adjustment mechanism is required.

[0099] The above embodiments of this utility model can be combined with each other and have corresponding technical effects.

[0100] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
