Description

Technical Field

[0001] The present invention relates to the technical field of space folding and unfolding mechanisms in aerospace, and particularly to an automatic double-flanging mechanism for a cylinder body. Background Art

[0002] In the technical field of space folding and unfolding mechanisms in aerospace, traditional mechanisms face many technical bottlenecks. For example, the lack of modular design makes maintenance complex, it is difficult to coordinate stiffness and unfolding function, and the problems of efficiency and precision caused by asynchronous flanging during unfolding.

[0003] Firstly, the modularity is low and maintenance is difficult. Some existing space folding and unfolding mechanisms do not adopt modular design, and various functional components are integrated with each other, resulting in the need to disassemble the entire mechanism during maintenance. This not only takes time and effort, but also easily damages other components, increasing the maintenance cost. Secondly, it is difficult to balance stiffness and unfolding function. When designing traditional folding and unfolding mechanisms, it is often difficult to meet the requirements of both stiffness and unfolding function at the same time. Some mechanisms use overly flexible structures to achieve the unfolding function, resulting in insufficient stiffness and easy deformation when bearing loads, affecting the normal use of the mechanism; while some other mechanisms make the structure design too rigid to ensure stiffness, restricting the unfolding effect, making the mechanism unfold inflexibly or unable to fully unfold. Finally, the unfolding is asynchronous, and the efficiency and precision are low. During the unfolding process of some existing flanging mechanisms, the two sides of the flanging may be asynchronous, with one side unfolding fast and the other side unfolding slow. This not only affects the unfolding efficiency, but also causes the flanging shape and position not to meet the requirements, reducing the precision and reliability of the mechanism.

[0004] In summary, the existing space folding and unfolding mechanisms face problems such as low modularity, difficult maintenance, difficulty in balancing stiffness and unfolding function, and insufficient efficiency and precision caused by asynchronous unfolding. There is an urgent need for an innovative mechanism with modular design, balanced stiffness and unfolding performance, and synchronous double-flanging ability to break through the technical bottlenecks. Summary of the Invention

[0005] To solve the problems of low modularity, difficult maintenance, difficulty in balancing stiffness and unfolding function, and insufficient efficiency and precision caused by asynchronous unfolding in space folding and unfolding mechanisms, the present invention provides an automatic double-flanging mechanism for a cylinder body.

[0006] The technical solution adopted by the present invention is as follows:

[0007] An automatic double flanging mechanism for a cylinder body, comprising a driving module, a flanging module, a first flanging sub-mechanism, a second flanging sub-mechanism, a reverse-threaded screw rod, a non-flanging strip, a side support circular tube, and a sleeve module. The first flanging sub-mechanism includes 21 discs, 21 large outer threaded sleeves, 21 outer threaded sleeves, 21 screw-threaded sleeves, 21 flanging strips, 21 bracket cranks, 21 flanging strip brackets, 21 straight connecting rods, 21 connecting rod brackets, and 21 inclined connecting rods. The second flanging sub-mechanism includes 22 discs, 22 large outer threaded sleeves, 22 outer threaded sleeves, 22 screw-threaded sleeves, 22 flanging strips, 22 bracket cranks, 22 flanging strip brackets, 22 straight connecting rods, 22 connecting rod brackets, and 22 inclined connecting rods.

[0008] Preferably, the driving module includes a motor cover, a motor, a motor flange, and a coupling coaxially installed in sequence. The motor cover is connected to the motor flange by M6 internal hexagon socket head screws.

[0009] Preferably, the first flanging sub-mechanism and the second flanging sub-mechanism are two sets of reversely installed flanging sub-mechanisms, both of which are synchronously driven by the reverse-threaded screw rod.

[0010] Preferably, there are eight non-flanging strips, which are arranged at intervals on the outer edge of the flanging module.

[0011] Preferably, the sleeve module includes a turbine flap, an intermediate steel pipe, an external PVC sleeve, a sleeve end cover, and an end cover bush installed coaxially in sequence.

[0012] Compared with the prior art, the advantages of the present invention are as follows:

[0013] The present invention is modularly designed with clear functions and easy to maintain. The automatic double flanging mechanism for the cylinder body is divided into three independent modules: a driving module, a flanging module, and a sleeve module. This modular design enables each module to be optimized designed and manufactured separately. The driving module can accurately provide power, the flanging module focuses on realizing the flanging function, and the sleeve module plays a good role in support and guidance. Each module has a clear division of labor and cooperates with each other to ensure the efficient operation of the overall mechanism. At the same time, the modular structure is convenient for installation, debugging, and maintenance. When a certain module fails, only this module needs to be replaced or repaired, without large-scale disassembly of the entire mechanism, greatly reducing the maintenance cost and time, and improving the maintainability and practicality of the mechanism.

[0014] The present invention has an ingenious structure, taking into account both rigidity and deployment requirements. The flanged strips and non-flanged strips on the outside of the cylinder of the flanged module are spaced apart. The non-flanged strips maintain their original basic structure, which can meet the strict requirements of the aerospace field for the rigidity of the mechanism, ensuring that the mechanism will not be excessively deformed when subjected to various complex loads, and providing stable support for the entire spatial folding and unfolding mechanism. The flanged strips are specifically used to meet the structural requirements for deployment, and through reasonable design, they can be smoothly deformed when they need to be deployed, thereby driving the entire mechanism to complete the deployment action. This spacing distribution method cleverly combines rigidity assurance and deployment function, avoiding the problem of sacrificing rigidity in pursuit of deployment function or limiting the deployment effect in order to ensure rigidity in traditional mechanisms, and achieving a good balance between the two.

[0015] The present invention has synchronous double flanging, which improves the deployment efficiency and precision. The flanging strip is disconnected from the middle and flipped to both sides, which can realize the automatic double flanging deployment and forming synchronously on both sides. During the deployment process, the flanging actions on both sides are carried out simultaneously, avoiding the asynchronous phenomenon that one side is deployed first and the other side is deployed later in the traditional mechanism, and ensuring the stability and consistency of the deployment process. This synchronous deployment method not only improves the deployment efficiency and shortens the time required for the deployment of the mechanism, but also can accurately control the shape and position of the flanging, ensuring that the deployed mechanism meets the design requirements and improves the precision and reliability of the mechanism. Automatic double flanging deployment and forming reduces manual intervention and reduces the impact of human factors on the deployment of the mechanism, and is more suitable for application in fields such as aerospace that require a very high degree of automation.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] As Figures 1 to 5 shown, the automatic double-flanging mechanism of the cylinder body in this embodiment includes a driving module 1, a flanging module 2, a sleeve module 3, a motor cover 11, a motor 12, a motor flange 13, a coupling 14, an M6 hexagon socket head cap screw 15, a flanging sub-mechanism one 21, a flanging sub-mechanism two 22, a reverse-thread screw rod 201, a non-flanging strip 202, a side support round tube 203, a 21 disc 2101, a 21 large outer thread sleeve 2102, a 21 outer thread sleeve 2103, a 21 screw rod thread sleeve 2104, a 21 flanging strip 2105, a 21 bracket crank 2106, a 21 flanging strip bracket 2107, a 21 straight connecting rod 2108, a 21 connecting rod bracket 2109, a 21 inclined connecting rod 2110, a 22 disc 2201, a 22 large outer thread sleeve 2202, a 22 outer thread sleeve 2203, a 22 screw rod thread sleeve 2204, a 22 flanging strip 2205, a 22 bracket crank 2206, a 22 flanging strip bracket 2207, a 22 straight connecting rod 2208, a 22 connecting rod bracket 2209, a 22 inclined connecting rod 2210, an intermediate steel pipe 31, an external PVC sleeve 32, a turbine flap 33, a sleeve end cover 34, and an end cover bush 35.

[0025] The automatic double-flanging mechanism for the cylinder is divided into three independent modules: drive module 1, flanging module 2, and sleeve module 3. Drive module 1 precisely provides power, flanging module 2 focuses on flanging, and sleeve module 3 provides excellent support and guidance. Each module has a clear division of labor and works in tandem, ensuring efficient operation of the entire mechanism.

[0026] The flanging module 1 has disc 21 2101 and disc 22 2201 at either end, with eight non-flanging strips 202 fixed at intervals to the outer rings of discs 2101 and 2201. The non-flanging strips 202 maintain their original basic structure, meeting the strict requirements for mechanical rigidity in the aerospace field, ensuring that the mechanism will not deform excessively when subjected to various complex loads, and providing stable support for the entire spatial folding and unfolding mechanism. The flanging sub-mechanism 21 has eight flanging strips 2105 of the same size at intervals, disconnected from the middle, one end fixed to the bracket crank 2106, and the other end free. The bracket crank 2106 is hinged to the flanging strip bracket 2107. The flanging strip bracket 2107 is fixed to the edge of the disc 2101. Flanging sub-mechanism 1 (21) consists of eight straight connecting rods (2108) hinged at one end to the support crank (2106) and at the other end to the threaded sleeve outer sleeve (2102). Further in the middle, four diagonal connecting rods (2110) hinged at one end to the threaded sleeve outer sleeve (2102) and at the other end to the threaded sleeve outer sleeve (2103). The threaded sleeve outer sleeve (2102) is connected to the discs (2101) and (22) at its ends via four side support tubes (203). Flanging sub-mechanism 2 (22) shares the same components as flanging sub-mechanism 1 (21) but is installed in reverse.

[0027] During flanging, motor 12 rotates and drives counter-threaded screw 201, causing threaded sleeve outer sleeve 2103 of flanging sub-mechanism 1 21 to move toward the center. This in turn causes oblique connecting rod 2110 to push threaded sleeve outer sleeve 2102 toward the end. Threaded sleeve outer sleeve 2102, via straight connecting rod 2108, pushes bracket crank 2106 to flip outward around flanging strip bracket 2107. Simultaneously, corresponding parts of flanging sub-mechanism 2 22, mounted opposite flanging sub-mechanism 1 21, perform opposite movements, achieving synchronized automatic double flanging. This synchronized deployment method not only improves deployment efficiency and shortens the time required for deployment, but also enables precise control of the shape and position of the flanging, ensuring that the deployed mechanism meets design requirements and improving its accuracy and reliability.

[0028] The above are only the embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. For those skilled in the art of this technology, the improvements and transformations obtained without departing from the technical concept of the present invention should also be regarded as the protection scope of the present invention.
