specific Embodiment approach 1

[0026] The aircraft model assembly method oriented to 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 from Massachusetts Institute of Technology, the research, application and development of Toyota production methods on a global scale has promoted the emergence of lean production theory and production management system, which is still evolving and developing. From Kaizen, which focused on the production site in the past, to inventory control, production planning management, process improvement (process reengineering), cost management, employee literacy development, supply chain collaborative optimization, product life cycle management (product concept design, product development, production line design) , workbench design, operation method design and improvement), quality management, equipment resour...

specific Embodiment approach 2

[0038] Different from the specific embodiment 1, the aircraft model assembly method oriented to lean production in this embodiment, the three-dimensional simulation process of the aircraft model described in step 1 is specifically:

[0039] Step 11: Measure the specific size of the aircraft model parts with a vernier caliper;

[0040] Step 1 and 2: Carry out 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 actual viewing angle;

[0041] Step 1 and 3: Use the 4-digit coding principle to code the 3D simulation drawing of each aircraft model part, for example, the code of the yellow rubber pad is 1402.

specific Embodiment approach 3

[0043] The difference from the specific embodiment 1 or 2 is that in the aircraft model assembly method oriented to lean production in this embodiment, the balancing method described in step 5 is: find out the sub-assembly process with the minimum man-hour adjacent to the bottleneck process, and Calculate and average the man-hours of the identified bottleneck processes, then decompose the bottleneck process into processes, assign the assembly process with more than the average man-hours to the sub-assembly process with the smallest man-hours, and complete the balanced production process of the general assembly path. After balancing, each sub-assembly process The effect of the man-hour trend of the assembly process is as follows: Figure 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 aircraft 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, at this stage, China's manufacturing industry is still of an extensive type. The enterprise promotes lean production, trying to improve the backward production management level of the enterprise. Many enterprises blindly imitate the implementation experience of foreign countries and rigidly introduce lean production to enterprises. The middle and high-level management cannot deeply understand the essence of lean production, which leads to the inability of enterprises to establish a good awareness of lean improvement. Lean production has finally become a slogan and movement. [0003] The existing aircraft model assembly schemes generally use folding paper airplanes as the production background. Under this p...
