柴油机气缸体三面粗镗组合机床总体及镗模设计
摘要:组合机床是以系列化、标准化的通用部件为标准,配以少量的专用部件组成的一种高生产率专用机床。它具有自动化程度较高,加工质量稳定,工序高度集中等特点。本次课题是设计一台加工S195型柴油机气缸体水箱面、油底壳面和后盖板面孔系的粗镗组合机床,具体进行总体设计和镗模设计。被加工零件为S195型柴油机气缸体,工件材料为HT200,三个面共加工13个孔,工件一次装夹,三面同时加工。为满足设计要求,进行工艺设计,确定所需的“三图一卡”。机床配置型式为单工位三面卧式组合机床,刀具选用镗刀。根据工艺过程的需要对工件的定位夹紧方式进行分析,设计满足使用的夹具,夹紧方式为液压夹紧。本组合机床,成本低,工作可靠,结构简单,装卸方便,便于维修、调整,加工精度高,操作使用方便,减轻了工人的劳动强度,提高了劳动生产率。

The Overall and Jig Design of Three-side Boring Modular Machine Tool for Cylinder Body of Diesel Engine
Abstract: The modular machine tool is based on serialization and standardization of the ponents of the standards, coupled with a small number of ponents, which is consisted of a special high productivity machine. It has such characteristics, high degree of automation , stable process quality, highly working procedure centralize. The subject design is a Three-side boring modular machining tool which processes water tank face, oil rind face and back cover board face of S195 cylinder body of diesel engine. The overall and jig design is important. Processed parts for cylinder block of S195 diesel engine, the tap of workpiece material is HT200, it bores 13 holes on the three faces, the workpiece is fixed one time, the three faces are processed at the same time. To meet the requirements of the design, process design is necessary. “Three plans and one ca
