【摘要】：本文通过在减速机公司的实地调研,对其现有生产状况有了一定了解。在此基础上对其新型减速机产品进行简明介绍,着重对其在装配车间的生产流程进行了深入的实地调研分析,发现其在现有生产状态下生产效率不足以支撑公司年度销售。总结国内外工业工程的发展历程和主要应用案例,发现工业工程的技术方法对提高产量有很大帮助。因此确立了用工业工程方法来解决生产率问题的总体研究方向。根据这些研究本文首先运用流程程序图对新产品SG的齿轮箱和电机的装配流程进行分别描述,进而找出齿轮箱和电机装配线存在的不合理因素。通过这些分析最终发现新产品装配流程存在移动次数多,距离长,寻找活动多,工人易疲劳等使装配效率低的现状。通过使用“5W1H”提问技术发现导致这些现象的根本原因是现场和工作台布置不理想,装配流程有待完善。因此本文运用工业工程中方法研究技术针对这些问题进行改善,降低了装配时间,减少了多余的移动和寻找等造成第一类动作延缓的不必要动作,减少了工人的移动距离,改善了工作台布置和工装工具的摆放方式,降低了工人的作业疲劳度。改善后每天可装配量由原来的40台增长为60台,产量明显提高。通过对改善方案与原有装配流程对比,验证了改善后方案的有效性。
[Abstract]:Through the field investigation in the reducer company, this paper has a certain understanding of its existing production situation. On the basis of this, the paper gives a brief introduction to its new reducer products. The production process in the assembly workshop is investigated and analyzed in detail. It is found that the production efficiency is not enough to support the company's annual sales under the existing production conditions. The development history and main application cases of industrial engineering at home and abroad are summarized. It is found that the technical methods of industrial engineering are of great help to increase the yield. Therefore, the general research direction of solving productivity problems by industrial engineering method is established. According to these studies, this paper first applies the process program diagram to the new production. Product SG gearbox and motor assembly process are described separately, Then find out the unreasonable factors in the gearbox and motor assembly line. Through these analysis, we find that the new product assembly process has many times of movement, long distance, more searching activities, By using the "5W1H" questioning technology, it is found that the root cause of these phenomena is the unsatisfactory layout of the site and worktable. The assembly process needs to be improved. Therefore, this paper uses the methods in industrial engineering to improve these problems, reduce the assembly time, reduce the unnecessary movement and search for unnecessary actions that cause the delay of the first kind of action. It reduces the distance of the workers' movement, improves the layout of the workbench and the arrangement of the tooling tools, and reduces the working fatigue of the workers.After the improvement, the daily assembly capacity is increased from the original 40 to 60. By comparing the improved scheme with the original assembly process, the effectiveness of the improved scheme is verified.
