Description

Technical Field

[0001] This invention relates to the field of engine assembly technology, specifically to an intelligent assembly line for piston-type aero engines. Background Technology

[0002] Currently, the assembly process for aero-piston engines adopts an on-site assembly method without conveyor lines. The planners distribute the required parts in quantitative quantities near the workbench, and employees assemble them directly at the workbench. After the engine is assembled, it is loaded into a transfer box and transported to the finished product area. This method is more common in small enterprises and is mainly suitable for small-batch production of engines.

[0003] A more common approach is to use a continuous roller conveyor line suitable for the product. This type of assembly line mainly consists of a drive unit, transmission unit, conveyor plates, and electrical control system. It allows for mass production and represents an effective combination of people and machines, fully demonstrating the flexibility of the equipment. It organically combines the conveyor system, accompanying fixtures, online special machines, and testing equipment to meet the assembly requirements of various product varieties. The conveyor method of the assembly line can be synchronous (forced) or asynchronous (flexible), depending on the configuration, enabling manual or semi-automatic assembly. While this improves assembly efficiency to some extent, this type of assembly line requires a relatively large number of operators and involves significant initial investment.
