中文题目：手柄座零件加工工艺与夹具设计 副 标 题： 外文题目：Processing technology and fixture design of handle base parts PAGE PAGE I PAGE PAGE II 摘 要 近些年以来，伴随一带一路政策深入的贯彻落实，经济发展的全球化趋势，机械行业的规模在该受惠于该政策的国家都得到了迅猛的发展。为了满足各式各样的差异化需要，机械产品的趋势倾向于专业、细分化，所以如何能够制造出同时兼备优异的质量和性能的设备已然变成制造商们关注的重点方向。同时竞争异常激烈的市场对于相关的机械部件行业有着更为苛刻的需求。设计出能够准确定位，安装精度高，夹紧力适中的高质量专用夹具是生产出高标准高质量的机械零部件的前提和关键。本次研究的课题是手柄座零件的加工工艺编制及专用夹具设计，课题研究的意义旨在通过对零件尺寸的工艺性分析编制出一套合理的加工工艺规程和设计出一些工序的专用夹具，以此来提高手柄座零件的生产质量、效率和经济性。本论文中的设计内容包括手柄座部件加工工艺以及相关工序所需的特殊夹具。在对相关的手柄座部件工艺进行分析的时候发现涉及到的是平面以及孔系。这当中如何确保孔系的精确度比平面要困难的多。所以在对工序进行设计的原则是多先粗后精，先面后孔。而且把孔和平面的加工步骤分为先粗后精两个加工阶段来确保孔系尺寸精度。以零件Φ25H8mm孔及其左右端面作为本次设计的主要定位基准。故在工序安排上是先加工出工艺孔，便于在后面的相关工序当中作孔定位对其它的孔以及平面进行加工。在对专用的夹具进行设计的过程中，对应的定位方式选择的是一面两销式，对于夹具的夹紧作用力以及定位误差进行分析和计算。 关键词：手柄座零件； 工艺； 夹具； 定位 ABSTRACT For the past few years, with the deep development of the policy for the the Belt and Road and the economic globalization, the scale of the machinery industry around the world has grown rapidly. In order to meet different needs, mechanical products tend to be specialized and differentiated. The production of high-quality and high-performance mechanical equipment has become the main direction of major manufacturers. The fierce market competition also puts forward higher requirements for the machinery parts manufacturing industry. Designing a high-quality special fixture with accurate positioning, high installation accuracy and moderate clamping force is the premise and key to produce high-standard and high-quality mechanical parts. The subject of this research is the processing technology compilation and special fixture design of handle seat parts. The significance of the research is to compile a set of reasonable processing technology procedures and design special fixtures for some processes through the process analysis of part size, so as to improve the production quality, efficiency and economy of handle seat parts. The main content of this design is to design the processing procedures of the handle seat part
