座体零件工艺及工装设计机械设计自动化专业论文设计

I座体零件工艺及工装设计 摘要：座体零件是一个典型的箱体类零件。本次设计的目标是设计座体零件的机械制造过程（即从零件的毛坯到最终成品的工艺设计）和三面钻孔和镗孔工装夹具设计。本次设计主要任务是对零件原料选择，铣削过程的安排，零件工艺设计加计算。 夹具会影响零件的尺寸精度和位置精度以及切削过程中的稳定性。在这次设计中，对座体的工装夹具进行完全定位设置，工件加工时被完全限制，准确性高。在设计完之前的内容后，通过AutoCAD 软件对其进行二维设计。关键词：AutoCAD；座体；工艺设计；工装夹具设计Technology and tooling design of seat partsAbstract: The seat part is a typical box type part. The goal of this design is to design the mechanical manufacturing process (that is, from the parts of the blank to the final product process design) and three surface drilling and boring fixture design. The main task of this design is the selection of raw materials for parts, milling process arrangement, parts process design plus calculation.Fixture will affect the dimensional accuracy and position accuracy of parts and the stability of cutting process. In this design, the fixture of the seat body is completely positioned and set, and the workpiece processing is completely limited with high accuracy. After designing the previous content, the two-dimensional design was carried out through AutoCAD software.
