ZQ型减速箱体机械加工工艺及夹具设计 摘 要 箱体零件是一种典型零件，其加工工艺规程和工装设计具有典型性。该箱体零件结构复杂，零件毛坯采用铸造成形。在加工过程中，采用先面后孔的加工路线，以保证工件的定位基准统一、准确。为了消除切削力、夹紧力、切削热和因粗加工所造成的内应力对加工精度的影响，整个工艺过程分为粗、精两个阶段。通过被加工零件的分析完成了机械加工工艺的设计及各加工工序机动时间的计算。根据箱体零件的结构及其功能，运用定位夹紧的知识完成了夹具设计。 关键词： 箱体，工艺，夹具 ABSTRACT This box machine element is typical, the manufacturing process and tooling design of it is typical.The structure of this box machine element is complicated, the machine element’s blank adopt casting shape. In the process of manufacture, in order to ensure th -e location datum accurate and unity, I adopt the manufacturing line from face to hole.In order to clear away the influence for machining accurate of internal stress, cutting force, clamping force, heat in cutting from coarse manufacturing, the whole manufacturing pro -cess is made of coarse and accurate manufacturing. Parts were processed through the a -nalysis of the complete machining process design and the manufacturing processes for mobile time calculations. According to the box components and the function and structu -re, the use of the knowledge positioning clamp completed the fixture design.
