For Mc And LP Auto Knuckle Production Quality Control And Its Key Technologies Reseach

Nowadays,the auto industry has developped rapidly all over the world, and China became t he manufacturing center of the world.In the manufacturing industry growing rapidly today, oppor tunities and challenges coexist. Playing self-advantages during the competition, using the conc ept of lean production, achieving the pattern of high-quality.high-efficiency. low-cost, maintaini ng the advantages of key technology, undoubtedly become the goal of the automotive industry. In this paper, Fof MC and LP automobile steering knuckle production quality control and key technology research,The study of the theory and the practice application will be combined. It researches and applies the field management, A flow, U line、Quality control means and so on. seeks good methods in knuckle lean manufacturing and solves the problems, Flexible use of Six Sigma, LP, MC and theoretical methods, to achieve a substantial increase in production efficiency, reduce manufacturing cost, save resources, reduce the waste, create maximum value.The main work of this thesis are as follows.1.Analysis of the domestic and foreign development status quo and trend of quality management, the quality control theory analysis and research, combined with the actual production situation of steering knuckle used in practice and experience2. For MC and LP automobile knuckle key technology in quality control of analysis and research, mainly based on process capability, The dimension chain calculating method, based on quality function deployment gage design technology research, explores the lean management technology and production line of Lean Improvement Technology3. Based on process capability calculation of dimension chain theory research and analysis, and get the optimum design and manufacturing solutions4. Based on quality function deployment gage design technology research, combined with the steering joint gage design requirements, for example analysis of the steering knuckle seized with the design idea and specific implementation methods5. The steering knuckle scene management technology research, elaborated the lean management technology in the steering knuckle production application, steering knuckle key tool technology research, innovation of the steering knuckle is, reverse taper hole machining key technology;The steering section of the production line for lean improvement analysis and research on the steering knuckle, process, production equipment beats, fixture design technology in detail to illustrate. On line and to improve the effect of the comparative analysis, summarizes the valuable experience.
