摘要
本设计的课题是减速箱箱体的上盖结构设计、箱体加工工艺规程制定及工艺装备设计。该箱体零件结构复杂,且为大批量生产,为了提高生产效率和降低劳动强度,专门设计了专用组合机床,专用夹具。本设计说明书可分为四部分:
第一部分为箱体的上盖结构设计。在上盖结构设计中,考虑下箱体的结构,合理选择上箱体结构尺寸、箱体壁厚、***孔大小等。
第二部分为箱体机械加工工艺规程的制定。在制定工艺过程中,确定各工序的安装工位和该工序需要的工步,加工该工序的机床及机床的进给量,切削深度,主轴转速和切削速度,最后计算该工序的基本时间,辅助时间和工作地服务时间。
第三部分为组合机床设计——组合镗床。更好的提高生产率,提高加工精度,降低生产成本。
第四部分为专用夹具设计。专用夹具的使用能有效降低工作时劳动强度、提高劳动生产率、并获得较高的加工精度。
关键词:箱体工艺组合机床夹具

Abstract

This design is the subject of gearbox top cover structure design, the processing technological process formulation and process equipment design. Replace parts of plex structure, and mass production, in order to improve production efficiency and reduce labor intensity, specially designed for the bined machine tool, fixture. The design specification can be divided into four parts:
The first part set box cover structure design, In the upper cover structure design, consider the box structure, reasonable selection box structure size, thickness of the box wall, hole size perspective.
The second part is technical regulations of the mechanical the development process, determine the installation position of each process and the process need the labor step, feed, machine tools and machining of the processes of the cutting depth, spindle speed, and cutting speed, the basic time finally calculated the procedures, work time and support to business hours.
The third part is bination of machine tool design -- combination boring lathe. Better to increase productivity, improve processing accuracy, reduce production cost.
The four part is the design of special fixture. The use of special fixture can reduce the work labor intensity, improve labor productivity, and obtain high machining accuracy.
Keywords: box technology modular machine tool fixture
