[0002] High-precision aerospace components play a crucial role in aircraft manufacturing, especially in the machining of long, plate-shaped parts. These components typically have high structural requirements and complex geometries, demanding machining accuracy down to the micrometer level to ensure their stability and safety during flight. Due to their unique shape and material properties, long, plate-shaped parts are prone to deformation and loosening during machining, thus placing higher demands on the precision and stability of the fixtures used in the machining process.

[0003] Existing high-precision aerospace component tooling fixtures mostly employ mechanical clamping, hydraulic control, or vacuum adsorption for positioning and fixation, which can meet the machining requirements of complex structural parts to a certain extent. The fixture structure typically includes a clamping mechanism, guiding components, and supporting elements, aiming to improve workpiece installation efficiency and machining accuracy. However, for machining long, plate-shaped high-precision parts, existing fixtures often suffer from problems such as uneven transmission and poor synchronization during clamping. Therefore, a high-precision aerospace component tooling fixture is proposed to address these issues. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-2This utility model provides an embodiment of a high-precision aerospace component tooling fixture, including a fixed frame 1. A fixing mechanism is installed inside the fixed frame 1, and a lifting mechanism is installed within the cavity of the fixed frame 1 to achieve stability of the aerospace components during processing or inspection. The fixing mechanism includes a rotating arm 3 and a fixing bolt 4. A limit rod 2 is fixedly connected inside the fixed frame 1. A guide groove is provided inside the rotating arm 3 to facilitate guiding and limiting the rotation process, improving the smoothness and coordination of the clamping action. The side wall of the rotating arm 3 is slidably connected inside the fixed frame 1. The limit rod 2 is located inside the guide groove, and the fixing bolt 4 is located inside the rotating arm 3 to achieve stability of the aerospace components during processing or inspection. The movement of the rotating arm 3 is guided by a hydraulic rod 5 fixedly connected to the top of the inner cavity of the fixed frame 1. The output end of the hydraulic rod 5 is fixedly connected to a moving plate 6. The moving plate 6 can move up and down under the force to complete the clamping and releasing process. The top of the moving plate 6 is fixedly connected to a fixed seat 7. The fixed seat 7 is rotatably connected to a rotating rod 8. Both ends of the rotating rod 8 are rotatably connected to the side wall of the rotating arm 3. The synchronous opening and closing is achieved through the lever linkage principle, which improves the consistency and coordination of the overall action of the fixture. When the moving plate 6 moves upward, the rotating arm 3 opens outward, which can quickly release aerospace parts and facilitate workpiece replacement and repositioning. When the moving plate 6 moves downward, the rotating arm 3 retracts.

[0031] Reference Figures 3-4 The lifting mechanism includes a lifting seat 9 and a push block 13. The side wall of the lifting seat 9 is slidably connected inside the fixed frame 1, enabling vertical guiding movement. A rotating roller 10 is rotatably connected inside the lifting seat 9, which effectively reduces frictional resistance during movement and ensures smooth and reliable lifting action. The push block 13 is installed inside the fixed frame 1, and a drive assembly for driving the push block 13 is installed inside the fixed frame 1. The drive assembly includes a motor 11 and a screw 12. The screw 12 is fixedly connected to the side wall of the fixed frame 1 and rotatably connected inside the fixed frame 1. One end of the screw 12 is fixedly connected to the side wall of the motor 11. The push block 1... 3. A threaded connection is made to the side wall of the screw 12. The screw 12 can be rotated by starting the motor 11, which in turn can drive the push block 13 to move. A slide plate 15 is fixedly connected inside the fixed frame 1. The push block 13 is set between the slide plates 15. A slider 14 is fixedly connected to the side wall of the push block 13. The side wall of the slider 14 is slidably connected inside the slide plate 15. One side of the push block 13 is set as an inclined surface. The rotating roller 10 can move along the inclined surface of the push block 13. When the push block 13 moves, it will guide the rotating roller 10 to move, thereby lifting the lifting seat 9 upward so as to lift the long plate part placed on the top of the fixed frame 1.

[0032] Working principle: When using this equipment to inspect long plate-shaped parts in aerospace components, the parts are first placed in the placement slot at the top of the fixed frame 1. Then, the hydraulic rod 5 is activated to drive the moving plate 6 to move downward, and the rotating rod 8 is deflected inside the fixed seat 7, which in turn drives the rotating arm 3 to move. The rotating arm 3 will flip under the guidance of the limit rod 2 and gradually come to a vertical position. As the rotating arm 3 continues to move downward, the fixing bolt 4 will finally fix the long plate part to ensure stability during processing.

[0033] After the parts are processed, the hydraulic rod 5 is activated to move the moving plate 6 upward, which causes the rotating arm 3 to open to both sides, making room above the parts. Then, the motor 11 is activated to drive the screw 12 to rotate, which causes the push block 13 to move. As the push block 13 moves, the rotating roller 10 will gradually come into contact with the inclined surface of the push block 13 and slide along the inclined surface. Guided by the push block 13, it will move upward and lift the lifting seat 9 upward so that the workers can pick up the parts.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
