1、 ZQ350 型减速机机体加工工艺及铣机 座结合面和钻 10-17 孔夹具设计 摘 要 本次毕业设计的题目是“ZQ350 减速器机体工艺规程及工装夹具设计” ，其主要任 务有两项：第一项是箱体零件加工工艺规程的设计；第二项是箱体零件工装夹具的设 计。在工艺规程的设计中，首先对零件进行分析，根据生产纲领、零件材料及其它要 求来确定毛坯的制造形式；其次根据基准选择原则进行粗基准和精基准的选择，然后 拟定工艺路线，通过综合比较与分析确定最终工艺方案；最后进行机械加工余量、工 序尺寸、毛坯尺寸、切削用量及基本工时的确定。在工装夹具部分的设计中，首先是 定位方案的确定，根据各道工序的加工特点合理的选择定

2、位基准并进行误差分析，如 果定位基准与设计基准不重合则要进行尺寸链的计算； 其次根据加工特点进行切削力 的计算，综合以上因素设计合理的夹紧方案并计算夹紧力，最后进行夹具整体设计。 关键词：减速器，工艺规程，工装夹具。 攀枝花学院本科毕业设计 （论文） ABSTRACT II ABSTRACT The title of graduation project is “the design of ZQ350 reducer body of technological procedure and assembly technology clamp “there are two main tasks:

3、The first is the design of technological procedure of box parts ,and the second is the design of assembly technology clamp of box parts .During the design of technological procedure, the first step is to analysis the parts according to production program, materials of parts and the other requirement

4、s ,and to determine the manufacture form of rough;the followed is to select rough and precise in accordance with the principles of reference, then deciding the process routes ,and detetmining the final programme by the Integrated Comparison and analysis ; the final is to determine mechanical allowan

5、ce, process dimension, blank dimensions, cutting parameters and the basic working hours. In the design of part of assembly technology clamp, the first is the determination of location programme,choosing location reference reasonably and analysising error in accordance with the characteristics of eve

6、ry process. if the location reference does not coincide with design reference , we must work out the dimension chain;the followed is the calculation of the cutting force by the characteristics of the processing .considering all the factors ,we will design the clamping programmes reasonably and calculate the clamping force, and design the clamp finally. Key words: reducer; technological procedure; assembly technology clamp 攀枝花学院本科毕业设计（论文） 目录 1 目 录
