specific Embodiment approach 1

[0025] The aircraft model assembly method for lean production in this embodiment, Lean Production (Lean Production), referred to as "Lean", is a management philosophy derived from the Toyota Production System. Including many well-known manufacturing companies and professors of Massachusetts Institute of Technology's research, application and development of Toyota's production method on a global scale, it has prompted the emergence of lean production theory and production management system, which is still evolving. Kaizen changed from the previous focus on production sites to inventory control, production planning management, process improvement (process reengineering), cost management, employee quality development, supply chain collaborative optimization, product life cycle management (product concept design, product development, production line design) , Workbench design, work method design and improvement), quality management, equipment resource and human resource management, ...

specific Embodiment approach 2

[0036] The difference from the first embodiment is that in the lean production-oriented aircraft model assembly method of this embodiment, the three-dimensional simulation process of the aircraft model in step one is specifically:

[0037] Step 1: Use vernier calipers to measure the specific dimensions of the aircraft model parts;

[0038] Step one and two: Perform 3D simulation of the aircraft model parts on the Solidworks simulation software interface according to the measured dimensions, and render according to the actual material of the aircraft model parts after determining the physical perspective;

[0039] Step 1: Adopt the 4-bit coding principle to encode the 3D simulation diagram of each aircraft model part, for example, the yellow rubber pad is coded as 1402.

specific Embodiment approach 3

[0040] The difference from the first or second embodiment is that the lean production-oriented aircraft model assembly method of this embodiment, the balance method described in step 5 is: find the sub-assembly process adjacent to the bottleneck process with the smallest labor time, and The working hours of the bottleneck process identified are done and averaged, and then the bottleneck process is decomposed, and the assembly process above the average working hours is assigned to the sub-assembly process with the smallest working time to complete the balanced production process of the overall assembly path. The effect of assembly process working hours is as Image 6 Shown.

Abstract

The invention discloses an airplane model assembling method for lean production and relates to an airplane model assembling method. The existing lean production method has the problem that the airplane model assembling efficiency is low, the production device layout is chaotic and disorder, the material movement is waste and the part is loss for transporting operation. The airplane model assembling method for lean production comprises the steps as follows: three-dimensional simulation modeling for the selected airplane model part entity and storing the three-dimensional simulation map in the form of source file and picture; confirming six groups of sub-assembly processes; using Solidworks for assembling three-dimensional entity of each sub-assembly body, rendering to obtain the three-dimensional simulation map of each sub-assembly body, forming the assembly sketch map process chart of the sub-assembly body; confirming airplane model general assembly path; confirming average assembly time for each sub-assembly process, finding the sub-assembly body process with more labor-hour as the bottleneck operation, finding the balancing method for realizing process balancing production; assembling the sub-assembly body; recording the delivery time after assembling the first and last airplane models; assembling for 3-5 times repeatedly. The airplane model assembling method for lean production is used for assembling airplane model.

Description

Technical field [0001] The invention relates to an airplane model assembly method oriented to lean production. Background technique [0002] The formation of global economic integration has brought more development opportunities to China’s manufacturing industry. However, China’s manufacturing industry is still extensive at this stage. In order to meet the challenges of advanced manufacturing in developed countries, many Chinese companies have begun to learn from Japan’s Toyota. The company promotes lean production and strives to improve its backward production management level. Many companies blindly imitate foreign implementation experience and rigidly introduce lean production to the company. The middle and senior management cannot deeply understand the essence of lean production. As a result, companies cannot establish a good sense of lean improvement. Lean production has finally become a slogan and movement. [0003] Existing airplane model assembly schemes generally use fold...
