Description

Technical Field

[0001] The utility model relates to an aviation engine saddle pad processing and positioning component. Background Art

[0002] Aircraft engine saddle pads, also known as engine brackets, engine hangers or engine racks, are an important component in the aircraft structure. They are used to fix the engine under the wing or fuselage of the aircraft. They mainly bear the weight of the engine and transfer these loads to the structure of the aircraft. The engine will vibrate when it is running. The saddle pads are designed with shock absorbing devices, such as rubber isolators or metal springs, to absorb and reduce the impact of these vibrations on the aircraft structure. Saddle pads are usually made of high-strength alloy steel or titanium alloy to withstand the gravity of the engine and the dynamic load during operation.

[0003] During the production process of aircraft engine saddle pads, it is necessary to ensure the precise position and stability of the saddle pads so that parts that meet strict aviation standards can be produced. However, traditional positioning equipment is often unable to accurately position saddle pads with complex or non-standard shapes, and requires manual assisted adjustment. This is not only inefficient, but also prone to errors due to improper operation, ultimately affecting the assembly quality and performance of the product. Utility Model Content
