毕业设计--车床尾座体的加工工艺及夹具设计（含全套图纸和工序卡片）.doc

摘要 洛阳理工学院毕业设计（论文） PAGE IV PAGE 28 车床尾座体的加工工艺及夹具设计 摘 要 本次毕业设计主要针对分析车床尾座体的形状构造，完成从毛坯到成品的加工艺方案的设计。通过对所设计方案的比较，选择出一套较为合理的加工工艺方案。对于所设计工艺方案中的某一指定工序还要进行工装夹具设计，并且画出装配图以及绘制出主要零件结构设计图纸。本次毕业设计的重点在于夹具的设计，孔的加工必须要以工件的底面作为基准，这样才能够使加工质量得到保证,因此所设计的加工工艺方案应该采取先面后孔的加工流程，这样才能够保证各处孔的加工精度。根据对各工序的加工工艺的分析，需要设计加工Φ17孔的专用夹具设计。在实际的生产过程中，它能有效的降低机械加工的劳动强度、提高劳动生产率、并且获得较高的精度和加工质量。 关键词：尾座体，工艺方案，夹具设计。 THE PROCESSING TECHNOLOGY AND FI×TURE DESIGN OF TAILSTOCK BODY ABSTRACT This graduation design is mainly aimed at analyzing the shape of the tailstock body structure, finish the process design from the blank to the finished product .By comparing the design scheme; i will select a reasonable process scheme. For the design of a specific process to design a special clamp, and draw the assembly drawings, and drawing out the main parts structure design drawings. This design will focus on clamp design, hole processing must be on the bottom surface of work piece as the benchmark, so the design of processing scheme should be Machining surface first and then processing hole, so as to ensure the machining accuracy of holes everywhere. According to the analysis of the processing technology of each process, I chose the processing the special clamp design of the hole of Φ17.In the actual production process, it can effectively reduce the labor intensity and improve labor productivity, and obtain high machining accuracy. KEY WORDS: Tailstock，Process program ，Clamp design. 前言 目　录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc358964675 前　言 PAGEREF _Toc358964675 \h 3 HYPERLINK \l _Toc358964676 第1章 零件的分析 PAGEREF _Toc358964676 \h 5 HYPERLINK \l _Toc358964677 1.1 零件的分析 PAGEREF _Toc358964677 \h 5 HYPERLINK \l _Toc358964678 1.1.1 零件的工艺分析 PAGEREF _Toc358964678 \h 5 HYPERLINK \l _Toc358964679 1.2 生产类型的确定 PAGEREF _Toc358964679 \h 6 HYPERLINK \l _Toc358964680 第2章 工艺规程设计 PAGEREF _Toc358964680 \h 7 HYPERLINK \l _Toc358964681 2.1 毛坯的制造形式 PAGEREF _Toc358964681 \h 7 HYPERLINK \l _Toc358964682 2.2 工艺规程的制定 PAGEREF _Toc358
