1、毕业设计论文I全套 CAD 图纸，加中文摘要非同步打标输送线是用来传输汽车凸轮轴的自动输送机器。本输送线采用纯机械离合装置，使小车走停更加灵活，可靠性能高，易于实现传输工件品种更换。具备外形美观大方，造价低廉等优点。本文为毕业设计论文，共分为七章。第一章绪论，第二章方案设计，第三章总体设计，第四章结构设计，第五章性能说明，第六章毕业设计总结与思考，第七章外文翻译。本毕业设计论文首先对传输机械，传输线发展现状进行概要的分析说明。然后对毕业设计题目提出的各种传动动作要求进行分解，寻找适合的设计方案。并进行初步的论证。采用非同步打标传输线，能够提高工艺水平，提高产品质量和生产效率，大大减轻劳动者的劳
2、动强度。改造后的机床更适合大批量的零件加工。对一个企业发展而言，成功的关键在于要实现以最好的质量，最低的价格， ，最短的时间去满足市场需求的不断的变化，因此使用传输线并努力提高其功效是成功的重要一环。从宏观上看，采用传输机械进行大规模的工作生产，除了在产品加工中实现自动化，降低劳动强度外，更重要的是在生产中采用传输机械，尤其是精密传输线，能降低人为失误，提高加工精度和效率。从微观上看，传输线有如下优点：加工精度高，产品质量好，生产效率高，毕业设计论文II柔性化程度高，工人劳动强度低等，同时节省人力费用一般小于购买一台传输线，降低了生产成本。本毕业设计重点对传输线中的离合小车，链轮的滑块张紧机构
3、，气动打标夹紧机构和传输线外框架进行了技术上的设计。另外，对电器控制部分采取plc 编程控制。论文中提出的车式传送装置采用上下轨道式，在传动链轮处设置了弧形弯道，使小车可沿此弯道平稳翻转。 我应用了刚带离合器的非同步传送小车，它结构简单，运行可靠，并能实现积累式小车存储。 关键词；非同步打标传输线 张紧机构 打标夹紧机构。AbstractNon-synchronization hit and mark and transmit line is a automatic transmission machine which is used for transmit car camshaft .
