[0002] In the aerospace field, composite fuselage panels are critical structural components of aircraft, characterized by their large size, significant curvature variations, and low rigidity. This makes efficient, high-precision, and consistently high-quality machining extremely challenging. Currently, large-sized hyperbolic composite fuselage panels are typically machined manually, resulting in low precision, low production efficiency, inconsistent product quality, and high costs. Automated machining can effectively address these issues; however, the design and application of machining fixtures are crucial in automated machining processes. Currently, there are few domestic research reports on the automated machining of composite fuselage panels, especially regarding machining fixtures. Conventional milling fixtures are mostly specialized fixtures, which, while meeting the machining requirements of specific panel configurations, suffer from large size, large space requirements, insufficient flexibility, and high costs, leading to persistently high production costs.

The second positioning component can be detachably connected to the hyperbolic wall panel through the corresponding lateral positioning hole to achieve circumferential positioning of the hyperbolic wall panel.

[0012] Furthermore, the first support member has a second positioning hole that is opposite to the corresponding lateral positioning hole, and the second positioning member can cooperate with the corresponding lateral positioning hole and the second positioning hole.

[0013] Furthermore, the second positioning member can be clearance-fitted with the corresponding lateral positioning hole and / or the second positioning hole.

[0017] The contact surface between the second support member and the hyperboloid wall panel is provided with a buffer layer.

[0018] Furthermore, each of the first support members is provided with a clearance groove corresponding to the hoisting interface of the hyperboloid wall panel.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0032] like Figures 1-3As shown, this embodiment provides an automated processing fixture for hyperboloid panels, used to clamp hyperboloid panels. The hyperboloid panel has end positioning holes at both ends along its flight direction. The automated processing fixture includes multiple vertically adjustable adjusting members 1, multiple support clamping assemblies spaced apart on both sides of the flexible support surface along its length, and first positioning members 4 located at both ends of the flexible support surface along its length, corresponding one-to-one with the end positioning holes of the hyperboloid panel. The multiple adjusting members 1 together form a flexible support surface adapted to the shape of the hyperboloid panel, allowing the flexible support surface to conform to the shape of the hyperboloid panel. The components are designed for fit and support of the hyperboloid panel. Each support and clamping assembly includes a first support member 2 and a first clamping member 3. The hyperboloid panel can be fitted to the first support member 2 on both sides along its flight direction. The first clamping member 3 is used to press and fix the hyperboloid panel onto the first support member 2, providing rigid support for both sides of the hyperboloid panel along its flight direction to maintain the shape of the hyperboloid panel. This achieves effective fixation of the processed edges of the hyperboloid panel, which helps to ensure that the panel shape matches the theoretical surface and prevents panel vibration from affecting processing accuracy during processing. The first positioning member 4 can be detachably connected to the hyperboloid panel through corresponding end positioning holes to achieve directional positioning of the hyperboloid panel. Here, the flight direction is the forward direction of the aircraft during flight, and the flight direction of the hyperboloid panel refers to the forward direction of the hyperboloid panel when it is installed on the aircraft.

[0033] By adjusting the vertical position of each adjusting component 1, a flexible support profile adapted to the hyperboloid panel is formed. During clamping, the hyperboloid panel is first placed on the flexible support profile. The corresponding first positioning component 4 is used to fine-tune both ends of the hyperboloid panel along its flight direction before fixing it, thus achieving positioning along its flight direction. Multiple first support components 2 provide rigid support for both sides of the hyperboloid panel along its flight direction. The first clamping component 3 fixes the hyperboloid panel to the first support component 2, achieving fixed clamping of the hyperboloid panel and maintaining its shape. Through the combination of the rigid support of the support clamping assembly and the flexible support profile, it can achieve... It ensures the compatibility of the fixture with the hyperboloid panel profile and provides sufficient edge support to guarantee machining positioning accuracy, thereby meeting the clamping requirements for automated machining of large-size hyperboloid panels and improving machining accuracy. Multiple adjustment components 1 can be flexibly adjusted to adapt to hyperboloid panels of different shapes and sizes, improving the flexibility and versatility of the fixture, reducing the investment in dedicated milling tooling, and helping to reduce production costs. The use of discrete lateral support clamping components can achieve flexible local adjustments while reducing the cost of the overall frame fixture in traditional solutions, reducing the fixture volume, and reducing the space occupied by the fixture in the factory.

[0034] like Figure 1 and Figure 2As shown, specifically, the first positioning member 4 includes a fixing part 41 and a plug-in part 42. The fixing part 41 has a first positioning hole that is opposite to the positioning hole at the end of the corresponding hyperbolic wall panel. The plug-in part 42 can be plugged into the positioning hole at the end of the corresponding hyperbolic wall panel and the first positioning hole to achieve positioning of both ends of the hyperbolic wall panel in the flight direction. Its structure is simple, the operation is quick, and it is easy to install and disassemble.

[0035] In other embodiments, the first positioning member 4 includes, but is not limited to, engaging or threading with the hyperbolic wall panel through corresponding end positioning holes, all of which can achieve positioning of the two ends of the hyperbolic wall panel in the flight direction, and are not limited here.

[0036] In this embodiment, the first clamping member 3 includes a fastener and a pressure plate. The fastener passes through the pressure plate, and one end is threadedly connected to the first support member 2. The other end is used to press and fix the pressure plate onto the first support member 2. The hyperboloid wall plate can be clamped between the pressure plate and the first support member 2. Optionally, the first clamping member 3 may include, but is not limited to, clamps.

[0037] Furthermore, the hyperboloid panel also has lateral positioning holes on both sides along its flight direction, such as... Figure 1 and Figure 3 As shown, the automated processing fixture for hyperbolic wall panels also includes multiple second positioning elements 5. Each first support member 2 is provided with a second positioning element 5, and the second positioning element 5 corresponds one-to-one with the lateral positioning holes of the hyperbolic wall panel. The second positioning element 5 can be detachably connected to the hyperbolic wall panel through the corresponding lateral positioning holes to achieve circumferential positioning of the hyperbolic wall panel, which helps to maintain the accurate shape of the hyperbolic wall panel and further improve the processing positioning accuracy.

[0038] Specifically, the first support member 2 has a second positioning hole that is opposite to the corresponding lateral positioning hole. The second positioning member 5 can cooperate with the corresponding lateral positioning hole and the second positioning hole. Through multiple discrete lateral positioning holes and the second positioning hole, circumferential positioning is performed, which can adapt to the curved shape of the hyperboloid wall panel and avoid deformation of the hyperboloid wall panel.

[0039] Optionally, the second positioning element 5 may include, but is not limited to, engaging or threading with the hyperbolic wall panel through corresponding lateral positioning holes, thereby enabling circumferential positioning of the hyperbolic wall panel, which is not limited here.

[0040] In this embodiment, the second positioning member 5 can be clearance-fitted with the corresponding lateral positioning hole and / or the second positioning hole. The clearance fit allows the second positioning member 5 to adapt to the slight deviation of the current curvature segment when inserted, avoiding the accumulation of internal stress in the hyperboloid panel caused by forced assembly.

[0041] Optionally, the second positioning element 5 may also be fitted with the lateral positioning hole or the second positioning hole in a transition fit or a threaded fit, which is not limited here.

[0042] It is easy to understand that the hyperboloid panel has multiple lifting interfaces, which are equipped with detachable connectors, such as bolts or nuts, to facilitate the connection of the hyperboloid panel to the output end of the lifting mechanism, such as... Figure 3 As shown in this embodiment, each first support member 2 is provided with a clearance groove 8 corresponding to the hoisting interface. The clearance groove 8 is used to accommodate the detachable connector, thereby avoiding interference between the detachable connector and the first support member 2. The detachable connector can pass through the clearance groove 8, so that the workers can disassemble and remove it. After clamping, the workers can use special tools to remove the detachable connector from the clearance groove 8, thus realizing the reasonable connection between each process.

[0043] like Figure 1 and Figure 2 As shown, the automated processing fixture for hyperboloid panels also includes multiple corner clamping assemblies. Each corner of the flexible support surface is provided with a corner clamping assembly. Each corner clamping assembly includes a second support member 6 and a second clamping member 7 disposed on the second support member 6. The corner of the hyperboloid panel can fit against the second support member 6. The second clamping member 7 is used to press and fix the corner of the hyperboloid panel onto the corresponding second support member 6, so that the hyperboloid panel fits more closely against the support surface formed by the flexible support surface and the second support member 6, further improving clamping stability and ensuring processing accuracy.

[0044] Specifically, the second clamping component 7 is a C-shaped clamp, which facilitates adjustment of the clamping angle and is suitable for clamping scenarios with limited space. It can better conform to the shape of the top corner of the wall panel for fixation. The specific structure of the C-shaped clamp is prior art and will not be described in detail here. Optionally, the second clamping component 7 may include, but is not limited to, pressure plates or clamps, which are not limited here.

[0045] In some optional embodiments, in order to prevent damage to the surface of the hyperboloid panel, a buffer layer is provided on the contact surface between the adjusting member 1 and the hyperboloid panel to avoid damage to the aerodynamic surface caused by the hyperboloid panel being squeezed by the adjusting member 1, thereby reducing the risk of the part processing.

[0046] Similarly, the contact surface between the first support member 2 and the hyperboloid wall panel is provided with a buffer layer; the contact surface between the second support member 6 and the hyperboloid wall panel is provided with a buffer layer to avoid damage to the aerodynamic surface caused by the hyperboloid wall panel being squeezed by the first support member 2 and the second support member 6. This will not be elaborated here.

[0047] The buffer layer may be made of materials including but not limited to rubber, nylon or silicone, and no specific material is specified here.

[0048] like Figure 2As shown, each adjusting member 1 includes a supporting part 11 and an abutting part 12. The abutting part 12 is movably connected to the top of the supporting part 11 and is used to fit against the contact surface of the hyperbolic wall panel. When the hyperbolic wall panel is placed on the flexible support surface, the abutting part 12 can automatically adjust to the angle of fitting against the hyperbolic wall panel under the force of the hyperbolic wall panel. This helps to increase the contact area between each adjusting member 1 and the hyperbolic wall panel, improve the fitting effect between the flexible support surface structure and the hyperbolic wall panel, and thus improve the clamping stability.

[0049] The abutment part 12 and the support part 11 are connected by, but are not limited to, universal joints or ball joints to achieve adaptive adjustment. The specific connection structure is prior art and will not be described in detail here.

[0050] Furthermore, the automated processing fixture for hyperboloid panels also includes an adjustment mechanism. The output end of the adjustment mechanism is connected to each adjustment component 1 for transmission, and is used to adjust the position of each adjustment component 1 in the vertical direction so that the flexible support surface matches the surface of the hyperboloid panel. The adjustment mechanism automatically adjusts the position of the adjustment component 1 according to the surface of the hyperboloid panel, so that the flexible support surface fits the hyperboloid panel completely, so that each part of the hyperboloid panel is precisely supported. It can quickly respond to changes in the shape of the hyperboloid panel, automatically complete the adjustment, shorten the preparation time, realize the rapid switching of continuous production of panels of different shapes, improve processing efficiency, shorten the production cycle, and improve equipment utilization.

[0051] Specifically, the adjustment mechanism includes a control system and multiple driving components corresponding one-to-one with the adjustment component 1. The output end of each driving component is connected to the corresponding adjustment component 1 via a transmission connection, and all driving components are communicatively connected to the control system. Under the control of the control system, the multiple driving components work together to adjust the flexible support surface, ensuring the accuracy of the fit between the flexible support surface and the shape of the hyperboloid panel. The driving components include, but are not limited to, hydraulic, pneumatic, or electric driving components capable of outputting linear motion; their specific structures are existing technology and will not be described in detail here.

[0052] In another optional embodiment, the adjustment mechanism includes self-locking bolts respectively disposed on each adjustment member 1 and springs disposed at the lower end of each adjustment member 1. During adjustment, the hyperbolic wall panel to be processed is first pressed onto the multiple adjustment members 1, so that the adjustment members 1 are compressed to a position that fits against the hyperbolic wall panel. Then, the position of each adjustment member 1 is locked by the self-locking bolts, thereby completing the adjustment of the flexible support surface.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
