Problems solved by technology

At present, the assembly of small bypass ratio aero-engines in China has been using the traditional operation mode for many years, which is characterized by intensive labor and is manually assembled around a fixed station based on a rigid frame. This operation mode has the following disadvantages: 1. People work collectively, the work efficiency is low, and there is a phenomenon of "slack work"; 2. There are many process contents, which easily lead to unclear quality responsibility subjects, high requirements for workers' technical level and poor assembly consistency; 3. The process layout is in The design and management are relatively messy, and it is impossible to form a "continuous flow" production operation mode
The above shortcomings of the traditional assembly operation mode seriously restrict the development of my country's aviation industry and affect the continuity of aviation equipment supply

Embodiment

[0055] Carry out the assembly of small bypass ratio aero-engines according to the technological process in the above content, record the working time of each pulsating station, take the first day after the technological process is optimized as the recording starting point, and take the 12-day general assembly process as a recording cycle ;Taking station No. 2 as an example, the daily working hours are 195 minutes, 190 minutes, 185 minutes, 185 minutes, 180 minutes, 175 minutes, 170 minutes, 175 minutes, 165 minutes, 165 minutes, 160 minutes, 160 minutes . During the operation, it was found that the working time of each station showed a downward trend and gradually stabilized over time. The main reason is that the process content in each station is simpler than the traditional assembly mode, and the operation difficulty is reduced. Familiarity with the work content of the station increases the proficiency of the operation rapidly; and the working time of each station exceeds th...

Abstract

The invention discloses a method for optimizing a pulsating assembly line of an aero-engine with a small bypass ratio, which includes optimizing the assembly process flow, determining the pulsating beat, determining the pulsating station, determining the product flow mode between the stations, configuring station resources, optimizing the process layout and Pilot run. The present invention breaks the original "big pot meal" mode in which multiple people work collectively, greatly reduces the number of workers at each station, realizes the fine management and operation of each station, eliminates the phenomenon of "slacker work", and improves the use of labor The process content of each station is simplified, the process division is more clear, the main body of quality responsibility is clear, and the requirements for the skill level of workers are reduced. As time goes by, the proficiency of workers will be greatly improved, and the consistency of assembly will be improved; The reform of engine assembly from "discrete mode" to "production line mode" has improved the on-site management level, assembly efficiency and assembly quality.

Description

technical field [0001] The invention relates to the technical field of aero-engine assembly, in particular to an optimization method for a pulsating assembly line of an aero-engine with a small bypass ratio. Background technique [0002] Aeroengine assembly is one of the most important links in the engine repair and manufacturing process. The level and quality of aeroengine assembly technology directly affect the operating characteristics of the engine. At present, the assembly of small bypass ratio aero-engines in China has been using the traditional operation mode for many years, which is characterized by intensive labor and is manually assembled around a fixed station based on a rigid frame. This operation mode has the following disadvantages: 1. People work collectively, the work efficiency is low, and there is a phenomenon of "slack work"; 2. There are many process contents, which easily lead to unclear quality responsibility subjects, high requirements for workers' tec...
