Technical Field
[0001] This utility model relates to the field of aerospace parts, and in particular to a tooling fixture for high-precision aerospace parts. Background Technology
[0002] Aviation components are the basic building blocks of aircraft (including airplanes, helicopters, drones, and other types of aircraft). From the fuselage frame of an aircraft to the tiny parts of the engine, from the structural components of the wings to the elements of the avionics system, these components each perform their own function and work together to ensure that the aircraft can operate safely and efficiently. They are the cornerstone of the aviation industry, and their performance and quality directly determine the overall performance and safety of the aircraft.
[0003] Aerospace component manufacturing is a core component of the aviation industry, and its manufacturing precision and quality directly determine the performance and safety of aircraft. Tooling and fixtures, as indispensable auxiliary equipment in the aerospace component processing, undertake the critical tasks of positioning and clamping components, ensuring that machining tools can precisely cut, drill, grind, and perform other operations on the components according to predetermined paths. From turbine blades in aircraft engines to key connecting parts in the fuselage structure, tooling and fixtures, like the skillful hands of a craftsman, precisely shape raw materials in the manufacturing of various aerospace components, laying the foundation for building high-performance aircraft.
[0004] When machining parts in aerospace equipment, tooling fixtures are required for positioning to prevent movement during machining and increase machining accuracy. However, existing tooling fixtures for aerospace parts cannot position parts of different sizes, and some parts need to be lifted for construction, which affects the applicability of tooling fixtures. Therefore, a high-precision tooling fixture for aerospace parts is proposed to solve the above problems. Utility Model Content

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 Figure 1-4This utility model provides an embodiment of a high-precision aerospace component tooling fixture, including a base plate 1. Four sets of rectangular blocks 2 are fixedly installed on the top of the base plate 1, and fixing blocks 3 are fixedly installed on both sides of the bottom of the base plate 1. A protective box 4 is provided at the bottom of the base plate 1, with the top of the protective box 4 and the bottom of the fixing blocks 3 fixedly installed. Limiting components 5 for limiting the aerospace components are provided on both sides of the top of the base plate 1, and an ejection component 6 for ejecting the aerospace components is provided at the bottom of the base plate 1. First, the aerospace components to be processed can be placed on the base plate 1, and then the aerospace components can be limited by the limiting components 5. At this time, the aerospace components can be drilled, ground, and other processes. When the aerospace components are processed, the aerospace components can be ejected by the ejection component 6 so that the workers can take the aerospace components away.
[0031] Reference Figure 1-4 The limiting assembly 5 includes two sets of rotating rods 51. The front and rear ends of each rotating rod 51 extend to the outside of the rectangular block 2 and are fixedly mounted with clamping blocks 52. The rotating rods 51 and the rectangular block 2 are rotatably mounted. Fixed sleeves 53 are fixedly mounted on both sides of the bottom of the base plate 1. An electric push rod 54 is fixedly mounted inside the fixed sleeve 53. A connecting sleeve 55 is fixedly mounted at the telescopic end of the electric push rod 54. A rotating block 56 is fixedly mounted on the surface of the rotating rod 51. The bottom of the rotating block 56 extends to the bottom of the base plate 1. The connecting sleeve 55 is movably mounted to the rotating block 56 via a shaft pin. Through the mutual cooperation of the rotating rods 51, clamping blocks 52, fixed sleeves 53, electric push rods 54, connecting sleeves 55, and rotating blocks 56, when the aircraft zero... When the component is placed on the base plate 1, the electric push rod 54 can be activated. The telescopic end of the electric push rod 54 drives the connecting sleeve 55 to move inward. The movement of the connecting sleeve 55 drives the rotating block 56, the rotating rod 51, and the clamping block 52 to rotate, thereby limiting the aerospace component. Subsequently, processes such as drilling can be performed on the aerospace component. Connecting plates 57 are provided on both sides of the top of the base plate 1. The outer side of the connecting plate 57 and the inner side of the clamping block 52 are fixedly installed. Several sets of clamps 58 are fixedly installed on the inner side of the connecting plate 57. Through the cooperation of the connecting plate 57 and the clamps 58, when the clamping block 52 rotates inward, the connecting plate 57 and the clamps 58 rotate inward, thereby stably limiting the aerospace component.
[0032] Reference Figure 1-4The ejection assembly 6 includes two sets of telescopic cylinders 61. The bottom of the telescopic cylinders 61 is fixedly installed on the bottom of the inner wall of the protective box 4. The telescopic end of the telescopic cylinder 61 extends through to the top of the base plate 1 and is slidably installed with the base plate 1. A push plate 62 is fixedly installed on the telescopic end of the telescopic cylinder 61. Through the cooperation of the telescopic cylinder 61 and the push plate 62, after the aerospace parts are processed, the telescopic cylinder 61 can be activated. The telescopic end of the telescopic cylinder 61 drives the push plate 62 to move upward. The push plate 62 moves upward and ejects the processed aerospace parts, thus facilitating their removal. A protective plate 63 is provided on the top of the push plate 62. The bottom of the protective plate 63 contacts the top of the push plate 62. The four corners of the bottom of the push plate 62 are detachably installed with the protective plate 63 by bolts. The protective plate 63 allows for... The protective box 4 is designed to protect aircraft parts from scratches caused by the push plate 62 when lifting them. Mounting blocks 7 are fixedly installed on both the front and rear sides of the protective box 4. Mounting slots 8 are formed on the top of the mounting blocks 7. Through the cooperation of the mounting blocks 7 and the mounting slots 8, the protective box 4 can be placed on a table. Bolts can then pass through the mounting slots 8 and be fixed to the table, allowing the entire box to be carried anywhere for operation. A threaded groove 9 is formed at the bottom of the protective box 4. A rotating ring 10 is installed inside the threaded groove 9. Through the cooperation of the threaded groove 9 and the rotating ring 10, when aircraft parts need to be lifted for processing, the rotating ring 10 can be rotated to enter the threaded groove 9. Then, a crane can lift the rotating ring 10, allowing the aircraft parts to be processed.
[0033] Working principle: First, the protective box 4 is fixed by passing bolts through the mounting slot 8. Then, the aerospace parts to be processed are placed on the bottom plate 1. Then, the electric push rod 54 can be activated. The telescopic end of the electric push rod 54 drives the connecting sleeve 55 to move inward. The movement of the connecting sleeve 55 drives the rotating block 56, the rotating rod 51 and the clamping block 52 to rotate. The inward rotation of the clamping block 52 will drive the connecting plate 57 and the gripper 58 to rotate inward, thereby limiting the aerospace parts. Then, the aerospace parts can be drilled and other processes can be performed.
[0034] After the aerospace parts are processed, the telescopic cylinder 61 can be activated. The telescopic end of the telescopic cylinder 61 drives the push plate 62 to move to the top. The push plate 62 moving to the top can push out the processed aerospace parts, so that the aerospace parts can be easily removed.
[0035] When it is necessary to lift some aerospace parts for processing, the rotating ring 10 can be rotated and will enter the threaded groove 9. Then the rotating ring 10 can be rotated to enter the threaded groove 9, and then the crane can lift the rotating ring 10, so that some aerospace parts that need to be lifted can be processed. Finally, the aerospace parts can be processed.
