1、 毕业毕业论文（设计）论文（设计） 题目：壳体零件的加工工艺规程 1 摘 要 本设计是一种壳体的工艺设计和夹具设计。该零件是一种支承和包 容传动机构的壳体零件。设计中先进行零件的结构和工艺分析，确定粗基准和 精基准以及零件的加工余量与毛坯的尺寸，得出零件的加工工艺过程，接着再 计算各工序的切削用量以及工时。除此之外，还设计了一套专用车床夹具和专 用钻床夹具。首先确定合适的定位基准，设计夹具体，再选择定位元件、夹紧 元件等部件。然后计算出定位误差、夹紧力以及切削力，分析夹具的合理性。 最后对关键部位进行 Proe 有限元分析，确保夹具可以安全的工作。 关键词：关键词：壳体 工艺分析 车床夹具 钻

2、床夹具 有限元分析 Abstract This design is a process design and fixture design of the shell. This section is a shell of supporting and embracing transmission mechanism. In the design, it should first process the structural and industrial analysis of the section, and then determine the coarse benchmark, fine

3、benchmark, machining allowance and blank size of the section to obtain the process of the parts making. After that it calculated the cutting dosages of every process and the production time. In addition, this design involved a set of special milling fixture and a set of special drill press fixture.

4、First, it identified the appropriate locating datum, chose clip specific. Then it chose positioning components, clamping component, and so on. It should also calculate the positioning error, clamping force, cutting force and then analyze the rationality of the fixture. Finally it had a finite-element analysis of the key parts to ensure that the fixture can work safely. Key words: Shell; Process analysis; Turning attachment; Drill jig; FEA 目 录 第 1 章 前言 0 第 2 章 引言
