机械制造工艺学课程是在学完了机械制造工艺学包括 机床夹具设计和大部分专业课,并进行了生产实习的基础上 的一个教学环节。这是我们在进行毕业设计之前对所学课程 的一次深入的全面的总复习,也是一次理论联系实际的训 练。因此,它在今年的学习中占有重要的地位。
我个人的感想是,希望经历了这次课程的设计,对自己 的将来所从事的工作,进行一次适应性的训练,通过这次课 程设计锻炼自己的分析问题,解决问题的能力,为毕业后的 工作打下一个良好的基础。
由于自己的理论知识的不完善,实践能力的缺乏,设计 之中不免有一些不合理的地方,恳请老师能够给予指教批 评。

第二章 确定毛坯
初步确定工艺安排为:加工过程划分阶段;工序适当集中;加工设备 以通用设备为主, 采用专用工装。 确定毛坏种类: 零件材料为 HT15-32,考虑零件在机床运行过程中所受冲击不大,零 件结构又比较简单,生产类型为中批生产,故选择砂型铸件毛坯。查 《机械制造工艺设计简明手册》第 41 页表 2.2-5,选用铸件尺寸公差 等级为 9。这对提高生产率,保证产品质量有帮助。此外为消除残余 应力还应安排人工时效。
第三章 工艺规程的设计

第五章 夹具设计

1 定位基准选择

底面对孔的中心线有一定的垂直度公差要求,因此应以地面为

主要定位基准..由于铸件的公差要求较大,利用小头孔的外圆表面作

为辅助定位基准时,只有采用自动对中夹具才能同时保证对称的两个

零件的大小孔的中心距的公差要求.为了提高加工效率,现决定采用两

把麻花钻同时加工出两个 ? 8mm 的通孔.

2 切削力及夹紧力计算

由于实际加工的经验可知,钻削时的主要切削力为钻头的切削

方向,即垂直于第一定位基准面,在两侧只需要采用两个 V 型块适当夹

紧后本夹具即可安全工作.因此,无须再对切削力进行计算.

本步加工可按钻削估算卡紧力。实际效果可以保证可靠的卡紧。

S pring for the development of China' s moder n industri al automati on technology the substantial i ncrea se in t he level of industria l automation, complete d the perfect relay of the computer too much. In terms of controll ing the computer s howe d his two great adva ntages: (1) each of the har dware can be installe d on one or more micr opr oces sors ; (2) the official designer of the s oftware writing content contr ol is all a bout. Now in sev eral ways in the context of industrial aut omation can often be s een i n three ways : (1) Programmable L ogical Contr oller (referred to as I PC); (2) Distributed Control System (DCS for s hort), and (3) the Programmable Logi cal Cont roller (PLC for s hort). 2. 1.2 PLC a nd the IPC and DCS contrast contrast 1, ea ch of the three te chnol ogies of origi ns a nd development requirements for fast data pr oce ssi ng makes it invented t he compute r.
