[0022] In addition, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the described aspects can be practiced without these specific details.

[0023] The currently existing fairing devices mainly have the following problems: 1. The general applicability of the shrouding device jig is poor. Usually, the jig is independently designed for the corresponding rocket model, with poor expandability for fairings of other lengths and great transportation difficulty. 2. The new composite fairing is prone to deformation, and it is easy for the connection interfaces between the two half fairings to be misaligned. There are deficiencies in the connection adjustment device at the separation surface between the jig and the fairing, resulting in great difficulty in docking the half fairings of the fairing. At the same time, there is no positioning and guiding when the two half fairings are docked, and stable positioning cannot be achieved during the final docking. 3. The docking connection between the jig and the pose adjustment mechanism requires high docking accuracy and has no guiding structure. 4. The pose adjustment mechanism usually needs to carry the jig for large-range adjustment, which has requirements for the flatness of the foundation plane. 5. The function of the pose adjustment structure is single, and precise six-degree-of-freedom adjustment of the jig cannot be achieved.

[0024] As Figure 1 shown, the vertical shrouding device for the satellite fairing in this embodiment includes a jig 1, a satellite support platform 2, an orbit group 3, a first pose adjustment mechanism 4, and a second pose adjustment mechanism 5.

[0025] As Figure 2 shown, this embodiment discloses a jig. The jig 1 is mainly composed of two symmetric half jigs, and the half jigs are welded by steel pipes. The jig is divided into three parts according to the characteristics of the fairing: a nose cone section 110, a straight section 120, and a tail cone section 130. The sections are connected and positioned by bolts and positioning pins. This segmentation mode is divided according to the structural characteristics of the fairing. For fairings of other model lengths, only an intermediate straight section module needs to be added. At the same time, the jig modules are relatively easier to transport after separation, reducing the product transportation cost. The jig has good rigidity, and independent modular adjustable interface ball head adjustment seats 160 are designed on the side of the jig. They are symmetrically designed along the xoz plane and are connected and fixed to the jig through long-hole bolts, used for docking with the longitudinal separation surface of the fairing to correct possible deformation before the fairing docking.

[0026] As Figure 2 shown, the ball head adjustment seats 160 are distributed corresponding to the distribution of the longitudinal separation surface interfaces of the fairing. As Figure 3As shown in the figure, the ball head adjusting seat 160 includes an adjusting screw 161, a positioning screw 164, an outer locking nut 162, an inner locking nut 165, a locking nut 166, a ball hinge bowl 167 and a mounting seat 163. Its mounting interface is an elongated hole, which can be adjusted within a small range in the Z direction on the side of the jig, reducing the dimensional accuracy requirements in this direction. The adjusting screw 161 and the positioning screw 164 are threadedly connected. The inner hole of the positioning screw 164 is a tapped thread, and the outer surface of the positioning screw 164 is a threaded structure. A through plane 168 is longitudinally arranged in the threaded structure. The plane 168 restricts the rotation of the positioning screw 164 in the mounting seat 163, but the positioning screw 164 can move back and forth in the mounting seat 163. The end hexagonal head of the adjusting screw 161 can be used in cooperation with tools to be screwed in the positioning screw 164. The end of the adjusting screw 161 is the connecting thread of the fairing, forming a stepped structure with its body thread, which can prevent the thread from being over-tightened when the adjusting screw 161 is connected to the fairing. After the connection interface between the adjusting screw and the fairing is fixed, loosen the outer locking nut 162, and by screwing the inner locking nut 165, the positioning screw 164 drives the whole adjusting screw 161 to move in and out, realizing the external pulling and internal pressing straightening of the fairing. This module can adapt to various possible postures of the fairing. After loosening the outer locking nut 162, the inner locking nut 165 and the locking nut 166, the positioning screw 164 can rotate at a small angle with the ball hinge bowl 167 to adapt to the small angular deviation of the connection interface of the fairing. After the angles are aligned, the inner locking nut 165 and the outer locking nut 162 can be tightened to fix the relative position of the positioning screw 164 and the mounting seat 163. After tightening the connection between the adjusting screw 161 and the fairing, further tighten the locking nuts 166 at both ends to fix the adjusting screw 161.

[0027] The ball head adjusting seat for the jig in this application can adapt to the position deviation of the fairing in the jig, reduce the equipment processing accuracy requirements, and reduce the connection difficulty between the fairing and the jig.

[0028] As Figure 4As shown in the figure, a docking guiding mechanism 150 is also symmetrically designed on the side of the jig along the xoz plane for guiding and positioning when two jigs approach and dock, so as to keep the relative positions of the two jigs fixed. The docking guiding mechanism 150 includes a horizontal guiding mounting base 151, an I-shaped horizontal sliding block 152, a guiding rod 153, a horizontal sliding block sealing plate 154, a locking nut 155, a vertical guiding mounting base 156, an I-shaped vertical sliding block 157, and a vertical sliding block sealing plate 158. Among them, the I-shaped horizontal sliding block 152 and the vertical guiding mounting base 156 are respectively installed on two independent half-jigs. The guiding rod 153 can be adjusted horizontally and vertically in cooperation with the I-shaped horizontal sliding block 152 and the I-shaped vertical sliding block 157 to meet the guiding and fixing function when the two half-jigs are not completely symmetrically docked. During docking, after adjusting the guiding rod 153 to insert into the I-shaped horizontal sliding block 152, it is connected and fixed through the long holes on the surfaces of the horizontal guiding mounting base 151 and the vertical sliding block sealing plate 158 and the bolt holes of the I-shaped horizontal sliding block 152 and the I-shaped vertical sliding block 157, and the relative positions are locked through the locking nut 155. Since at least two groups of docking guiding mechanisms 150 are distributed on the side of the jig, the relative positions of the jigs during docking can be ensured to remain unchanged. The docking guiding mechanism 150 on the jig also has the ability to adapt to the deflection angle.

[0029] As Figure 5 shown in the figure, a jig tensioning mechanism 140 is also designed on the side of the jig. This mechanism includes: a horizontal locking mounting base 141, an I-shaped horizontal locking sliding block 142, an end face locking nut 143, a horizontal locking sliding block sealing plate 144, a locking screw rod 145, an I-shaped vertical locking sliding block 146, and a vertical locking mounting base 147. This mechanism can also adapt to the situation where there is a certain misalignment during the docking of the two half-jigs, and drives the docking and tensioning between the fairing interfaces by tensioning the two half-jigs. Among them, the locking screw rod 145 is of a screw rod structure, and the I-shaped horizontal locking sliding block 142 and the I-shaped vertical locking sliding block 146 can slide horizontally and vertically. After the position of the jig is adjusted to align the fairing interfaces, the I-shaped horizontal locking sliding block 142 and the I-shaped vertical locking sliding block 146 can also be tightened and fixed through the long holes on the horizontal locking mounting base 141 and the vertical locking mounting base 147 and the threaded holes of the respective sliding blocks after adapting to the deflection angle. The locking screw rod 145 is also threadedly connected to the I-shaped horizontal locking sliding block 142 and the I-shaped vertical locking sliding block 146, and the relative positions are locked by the end face locking nut 143. Finally, the two half-fairings are tensioned by screwing the external hexagon in the middle of the locking screw rod 145.

[0030] As Figure 6 and Figure 7As shown in the figure, the nose cone section 110 of the tooling fixture is designed with a front lifting point interface 111, which is connected to a lifting eye bolt and cooperates with the rear lifting point 131 of the tooling fixture for lifting and flipping the tooling fixture. In addition, the installation position of the lifting point interface is adjustable. Since the cone section is a common module for various types of fairings, setting the lifting point structure on the cone section can ensure that when the column ends of the fairing combination device are increased or decreased later, the lifting point position is still at the head. That is, the position of the lifting installation port is adjustable, which can adapt to a certain range of centroid deviation and the change of the centroid position of the tooling fixture fairing combination, and ensure that the tooling fixture is in a vertical state during vertical lifting of the combination. In this embodiment, the nose cone adapter plate 112 is connected and fixed to the nose cone section 110 through bolts and positioning pins, and can be replaced according to the nose cone forms of different fairings to adapt to various types of fairings. The adjustable auxiliary support 113 is lifted and assisted in adjustment by combining a lead screw and a handwheel to reduce the deformation at the nose cone of the fairing.

[0031] As Figure 7 Shown in the figure is the bottom of the column section of the tooling fixture, including the rear lifting point 131 of the tooling fixture, the tooling fixture leg 132, the fairing support ring 133, and the fairing guiding and positioning U-groove 134. The tooling fixture leg 132 is detachably connected to the tooling fixture through bolts, and the leg can continue to be used when replacing the tooling fixture with other diameters later. As Figure 8 Shown in the figure, a positioning hole 135 and a limit hole 136 are opened at the center of the bottom of the leg for connecting and locking the degrees of freedom with the first pose adjustment mechanism 4 and / or the second pose adjustment mechanism 5. The fairing support ring 133 provides support when the fairing falls into the tooling fixture. The fairing guiding and positioning U-groove 134 opened on the side of the tooling fixture cooperates with the guiding rod on the fairing to determine the relative position of the fairing and the tooling fixture in the oz direction, reducing the docking difficulty of lifting the fairing into the tooling fixture.

[0032] As Figure 9 Shown in the figure is the composition diagram of the first pose adjustment mechanism 4, including the tooling fixture connecting plate 401, the ball hinge limit pin 402, the leg guiding pin 403, the ball hinge seat 404, the lateral force balance column 405, the ball hinge seat fixing frame 406, the vertical elevator 407, the vertical scale 408, the vertical elevator mounting seat 409, the horizontal scale 410, the rotating lifting eye 411, the roller type horizontal slide rail 412, the slide rail limit 413, the brake 414, the roller 415, and the horizontal adjustment elevator 416. The difference between the second pose adjustment mechanism 5 and the first pose adjustment mechanism 4 is that the second pose adjustment mechanism 5 does not have the horizontal adjustment elevator 416 and follows in the oy direction when the horizontal adjustment elevator 416 of the first pose adjustment mechanism 4 makes a horizontal adjustment. The horizontal adjustment elevator 416 drives the vertical elevator mounting seat 409 to move on the roller type horizontal slide rail 412 through a lead screw. When the tooling fixture and the fairing are not completely parallel, there will be an angular deviation between the two tooling fixtures during the docking of the two half fairings. At this time, the first pose adjustment mechanism 4 is required to adjust the angle. The tooling fixture legs 132 are evenly distributed in three at the bottom of the tooling fixture, and a stable support state can be formed after being connected and combined with the first pose adjustment mechanism 4.

[0033] The first pose adjustment mechanism 4 is connected to the jig through the jig connecting plate 401, and the leg guide pin 403 can be used for guiding during docking. The ball hinge limit pin 402 is a limit pin for locking the ball hinge. After the jig is connected to it, the overall stability can be ensured when moving in a large range in the ox direction on the track group 3. When the two jigs are close and fine-tuning docking is required, the ball hinge limit pin 402 needs to be pulled out to release the freedom of the ball hinge. By adjusting the height of the vertical lift 407 of the two pose adjustment mechanisms, namely the first pose adjustment mechanism 4 and the second pose adjustment mechanism 5, various pose adjustments such as the overall elevation, overall lowering, pitching rotation around the oy axis, and rolling around the ox axis of the jig can be achieved. For the rotation working condition around the oz axis, it is necessary to keep the first pose adjustment mechanism 4 locked in position on the track group 3 through the brake 414, and by pushing the second pose adjustment mechanism 5 to move back and forth on the track group 3, the overall rotation of the jig around the ball hinge where the first pose adjustment mechanism 4 is located can be realized. The oy direction of the second pose adjustment mechanism 5 is a horizontal slide rail, so the overall rotation angle can be calculated according to the moving distances of the vertical lift mounting seat 409 of the second pose adjustment mechanism 5 in the ox and oy directions. Different from other types of cover closing devices, this device has the ball hinge built into the pose adjustment mechanism and is connected to the jig through guiding. The ball hinge joint is protected because it is not exposed, and the docking operation becomes convenient.

[0034] As Figure 10 、 11 shown in the structural composition of the track group, the track group provides a guiding track in the ox direction for the first pose adjustment mechanism 4 and the second pose adjustment mechanism 5 of the pose adjustment mechanism. The track group is composed of 6 track units combined. The middle track unit is connected to the satellite support platform 2 through the v-shaped guide pin 309 shown in Figure 11 . This guiding form is convenient for the up and down unrestraint during the track height adjustment and at the same time provides a median reference during the cover closing docking. After the guiding is completed, it is connected and fixed to the satellite support platform 2 through the track unit fixed interface 308. The track units are connected through the track bearing frame adjustable connecting rod 310. The adjustable connecting rod 310 is in the form of a telescopic sleeve driven by a thread. Taking the middle track as the reference, as shown in Figure 1As shown, after the three groups of tracks on one side are connected, a triangular stable structure is formed between the connecting rods, which also facilitates determining the relative positions during installation. The track unit itself includes a track bearing frame 301, a track 302, track rollers 303, track footrests 304, track end limiters 305, corner fine-tuning mechanisms 306, spirit levels 307, and track unit fixed interfaces 308. Among them, the track rollers 303 are used to facilitate pushing and positioning during the combined installation of track units. The track footrests 304 and the spirit levels 307 can be used together to level the tracks and avoid large-angle tilting. The track end limiters 305 are limit structures to prevent derailment when the pose adjustment mechanism reaches its extreme stroke. The main function of the corner fine-tuning mechanisms 306 is that when the rollers of the pose adjustment mechanism press against the corner fine-tuning mechanisms 306, by adjusting the screws of the corner fine-tuning mechanisms 306, the relative positions of the rollers on both sides of the middle part of the pose adjustment mechanism and the track end limiters 305 can be finely adjusted, thereby adjusting the rotation of the entire jig around the z-axis.

[0035] As Figure 12 Shown is the satellite support platform 2 of the fairing device, whose main function is to provide fixation and support for the rocket support cabin, and at the same time provide a median reference for the installation of the track group. The satellite support platform 2 mainly consists of the following structures: an adapter ring 201, a satellite bearing frame 202, a track positioning connection port 203, satellite support platform support footrests 204, and satellite support platform rollers 205. Among them, the adapter ring 201 can be replaced according to different satellite support cabins, with good adaptability. The whole of the satellite support platform 2 can be leveled through the satellite support platform support footrests 204.

[0036] As Figure 13 、 Figure 14 and Figure 15 As shown, place the jig 1 on the bracket, hoist the fairing into the jig 1, flip and hoist the fairing to the vertical state and dock it with the pose adjustment mechanism, and push the two half-jigs together to complete the fairing closing process.

[0037] This embodiment has the following effects: 1. By modularly designing the jig, simply increasing or decreasing the jig modules can achieve the universality of fairings with different lengths and different nose cone forms. The jig is designed with a ball head adjustment seat, which can achieve the rapid connection of the fairing in the jig and internal pressure and external tension straightening. The pose adjustment mechanism group, in combination with the jig and the track, can achieve precise six-degree-of-freedom adjustment of the jig. Setting the ball head adjustment seat and the pose adjustment mechanism can achieve the universality of fairing closing for fairings with different lengths and different nose cone forms, reducing hardware investment; 2. The docking guiding mechanism enables the docking of the fairing and the jig to have guiding and positioning, making their docking and installation convenient and improving the docking efficiency; 3. The jig can achieve simple adjustment of the fairing separation surface, correct deformation, provide a stable guiding structure during docking to ensure smooth docking. The multi-degree-of-freedom ball hinge and guiding connection of the ball head adjustment seat increase the adjustment and adaptation ability, and reduce the machining accuracy requirements of the jig. 4. The jig is designed with a guiding connection to the pose adjustment mechanism, reducing the difficulty of hoisting and assembly. 5. The track group is modular, can be quickly leveled, and can be quickly guided and positioned based on the satellite support platform, improving the assembly efficiency. 6. The pose adjustment mechanism cooperates with the track to achieve six-degree-of-freedom adjustment, has low requirements for the ground levelness, and has strong docking adjustment ability.
