The external and internal quality of flywheel housing either impact on the overall diesel beautiful or affect the overall performance of diesel engines. the main structure of the flywheel housing of 110 diesel engine is the complex shape, thin wall and uneven, processing site, difficult process, various surface processing and processing Kong have higher accuracy. In this paper,the development of routes were based on the characteristics of components of the analysis components. Secondly, the identification of the parts of the production program, the type and manufacturer of rough form. Based on the first chapter of the analysis of two routes, its comparative analysis, According to its comprehensive advantages and disadvantages of other first benchmark, the first after crude refined, after the first meeting of the main principles of the machining program, as well as procedures for the detailed design. the fixture parts of the flywheel housing of 110 diesel engine according to of the design characteristics of the thin-walled parts is parts. Clamping in the process vulnerable to deformation, thus affecting the accuracy or even damaged parts. Equipment used two sets of the appropriate positioning and clamping, ensuring the accuracy of the components also ensure the integrity of the parts processing, Auxiliary while reducing working hours, improved labor productivity. In this paper, the flywheel housing was made a detailed technical analysis and research. the technology and equipment of a design was explored a new practicable path for this product.
