[0002] Aviation parts refer to the various parts and components that make up the airframe, engine and airborne equipment of aircraft (such as airplanes, helicopters, etc.). They are the core components of aircraft manufacturing and maintenance, and typically include metals, composite materials and electronic components.

[0003] Existing tooling for machining aerospace parts has poor applicability. Due to the diverse geometries of aerospace parts, such as cabin doors, wing panels, and seat plates, which have different shaped surface structures, specialized clamping fixtures are required to hold them during surface machining (such as drilling) to meet their unique machining needs. However, specially designed clamping fixtures not only require a significant investment of manpower, resources, and time in design and manufacturing, but also, due to their specific requirements, are difficult to reuse in machining parts with different shaped surface structures. This results in low tooling efficiency and further increases production costs. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application. It should be noted that, without conflict, the various features in the embodiments of this application can be combined with each other, and the combined embodiments are still within the protection scope of this application.

[0032] Existing machining fixtures for aerospace parts have poor applicability. Due to the complex geometry of aerospace parts, each part requires specially designed clamping fixtures to meet its unique processing requirements. These specially designed fixtures not only require significant investment of manpower, resources, and time in design and manufacturing, but also, due to their specific application, are difficult to reuse in the processing of other parts. This results in low fixture efficiency and further increases production costs. To address these issues, this application provides a machining fixture for aerospace parts with strong applicability.

[0033] like Figure 1 As shown, this application embodiment provides an aerospace part processing fixture, including a telescopic rod 20, a rotating assembly 30 and a clamping assembly 40 connected in sequence. The clamping assembly 40 is used to clamp the aerospace part; the telescopic rod 20 is used to be fixed on the support frame 10; the rotating assembly 30 is used to rotate the clamping assembly 40 relative to the telescopic rod 20; the number of processing fixtures is several, and the ends of the several processing fixtures with clamping assemblies 40 are close to each other.

[0034] This embodiment of the application can adapt to aerospace parts with different geometries by replacing the clamping component 40. Combined with the telescopic rod 20 and the rotating component 30, it can clamp aerospace parts horizontally and vertically, adapting to various processing scenarios and applicable to aerospace parts with different clamping requirements. It solves the problem of poor applicability of traditional fixtures, expands the scope of application, and reduces the cost of repeatedly developing special tooling. Through the combination of the telescopic rod 20, the rotating component 30, and the clamping component 40, multi-degree-of-freedom adjustment is achieved, reducing the time spent on frequent disassembly and re-clamping. The angle of the part can be flexibly adjusted. Since the rotating component eliminates the need for frequent disassembly and re-clamping of the part, the rapid adjustment function of the rotating component 30 allows the operator to complete multi-angle processing tasks in a short time, significantly improving production efficiency.

[0035] In one embodiment of this application, a clamping assembly 40 is suitable for vertically clamping and fixing aerospace parts. The clamping assembly 40 includes two opposing base plates 42 and a plurality of fasteners. The fasteners are connected to the base plates 42 via a driving structure, which drives the fasteners to move in a direction perpendicular to the base plates 42, thereby clamping the aerospace parts between the opposing fasteners. This clamping assembly 40 is suitable for thin-walled aerospace parts. In actual use, a support platform can be placed at the middle position of the thin-walled aerospace part to support it, such as... Figure 2 As shown, the edges of thin-walled aerospace parts are secured by multiple sets of clamping components 40.

[0036] The fasteners and base plate 42 can stably clamp aerospace parts, ensuring machining accuracy. The relatively arranged base plate 42 and fasteners can adapt to parts of different sizes, improving the versatility of the device and facilitating installation and use.

[0037] Specifically, such as Figure 3 and Figure 4 As shown, the fastener is a threaded rod 43, which vertically penetrates the base plate 42 and is threadedly connected to it. A handle 44 is provided at the ends of the two sets of threaded rods 43 that are far apart from each other, and a contact block 45 is provided at the ends of the two sets of threaded rods 43 that are close together. The contact block 45 is used to contact the aerospace parts. The operator can easily and quickly adjust the position of the threaded rod 43 by rotating the handle 44, improving work efficiency. The surface of the contact block 45 can be coated with engineering plastic (such as PEEK) or rubber to provide both anti-slip and protective functions, reducing damage to the surface of the parts.

[0038] In one embodiment of this application, it is suitable for clamping and fixing aerospace parts in a horizontal direction, such as... Figure 5 As shown, several pairs of machining fixtures are arranged in pairs, and the oppositely arranged machining fixtures are located on the same horizontal plane. The machining fixtures are arranged in pairs, and the corresponding machining fixtures are coaxial; the clamping assembly 40 includes a clamping plate 41, and the working surface of the clamping plate 41 is an irregularly shaped surface that conforms to the surface of the aerospace part to maintain the stability of clamping.

[0039] like Figure 6 As shown, the rotating assembly 30 includes a base 32 and a turntable 33 coaxial with and connected to the telescopic rod 20. The base 32 is fixed to the end face of the telescopic rod 20, and the turntable 33 is used to fix the clamping assembly 40. A protruding side plate 34 is provided on the edge of the turntable 33 facing the base 32, and the side plate 34 is fitted onto the outer periphery of the base 32. A plurality of first ball bearings 35 evenly distributed along the circumference are arranged between the opposing surfaces of the turntable 33 and the base 32, and a plurality of second ball bearings 36 evenly distributed between the opposing surfaces of the side plate 34 and the base 32, so that the turntable 33 can rotate relative to the base 32. The arrangement of the first ball bearings 35 and the second ball bearings 36 reduces the friction between the turntable 33 and the base 32, achieving smooth rotation. The turntable 33 can rotate quickly, facilitating rapid adjustment of the part angle by the machining operator. The second ball bearings 36 between the side plate 34 and the base 32 provide additional support, enhancing the stability of the structure.

[0040] Specifically, a fixing component is provided between the base 32 and the turntable 33 to secure them. In practical use, the base 32 and turntable 33 can be fixed as needed to facilitate parts processing. In one embodiment of this application, the fixing component is a hexagonal bolt 31, which penetrates the side plate 34 and is threadedly connected to it. The end face of the hexagonal bolt 31 abuts against the base 32. The operator can tighten the hexagonal bolt 31 as needed to fix the base 32 and turntable 33 or to allow them to rotate relative to each other, improving work efficiency.

[0041] This aerospace part machining fixture achieves multi-degree-of-freedom adjustment through a combination of a telescopic rod 20, a rotating assembly 30, and a clamping assembly 40. The clamping assembly 40 can be replaced according to the geometry of the aerospace part to adapt to different machining requirements. The telescopic rod 20 provides horizontal or vertical clamping capability, while the rotating assembly 30 achieves smooth rotation through a ball bearing design, reducing friction and facilitating quick adjustment of the part's angle. Operators can complete multi-angle machining tasks without frequent disassembly and re-clamping of the part using the rotation adjustment function of the rotating assembly 30. The clamping assembly 40 ensures clamping stability. Through flexible adjustment and efficient operation, the entire fixture significantly improves production efficiency and reduces the development cost of specialized tooling.

[0042] The manufacturing process of an aerospace part machining fixture provided in this application embodiment is as follows:

[0043] The operating procedure for this aerospace part machining fixture is as follows: The telescopic rod 20 is fixed to the support frame 10. A suitable clamping assembly 40 is selected based on the geometry of the aerospace part and installed on the rotating assembly 30. The length of the telescopic rod 20 is adjusted to meet the clamping requirements of the part, or the part can be clamped and fixed on both sides by extending the telescopic rod 20. The angle of the clamping assembly 40 is adjusted by rotating the assembly 30 to ensure the part is in the optimal machining position. For thin-walled parts, a support platform can be placed in the middle to provide additional support. The operator adjusts the position of the threaded rod 43 by rotating the handle 44, so that the contact block 45 is in contact with and clamped to the surface of the part. For multi-angle machining, the part angle can be quickly adjusted using the rotating assembly. If necessary, hexagonal bolts 31 are used to fix the base 32 and the rotating table 33 to ensure machining stability. After machining is completed, the threaded rod 43 is released, and the part is removed. The entire process is flexible and efficient, significantly improving production efficiency and reducing tooling development costs.

[0044] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
