设计简介
摘要：在全球经济发展的大环境下，中国各个行业被其他国家的先进技术影响的同时，越来越多的外国企业和品牌传播到中国已经成为现实。在新的市场需求的推动下，对可折叠儿童电动车进行改良和优化是当务之急。有大型可折叠儿童电动车生产制造企业对该型电动车的安全指标的有着一定生产的严格要求。在生产企业，需要充分考虑到在儿童在骑电动车时可能出现的问题，从而减少对儿童人身安全以及由于车身重，骑乘困难、不方便现象等。国内可折叠儿童电动车的研发及制造要与全球号召的高效经济、安全稳定主题保持一致。可折叠儿童电动车的发展与人类社会的进步和科学技术的水平密切相关。因此，本文首先就方案的选择进行了研究。通过设计者掌握的专业基础知识，互联网上的相关资料以及国内外已有的设计种类的现状，经过详细的方案调查，为本次毕业设计设计出了一套实用的可折叠儿童电动车。
论文方案选择的论证开始，详细介绍了方案分析、设计流程和计算流程，并进行了必要的动力系统总体结构设计。主要用于实现方便于儿童乘坐，推行的设计，进一步体现人文关怀。

Abstract：The environment of global economic development, China industries affected by other countries advanced technology at the same time, foreign enterprises and brand spread to more and more Chinese has become an opportunity. Cap pressing machine in industry through a variety of ways have been working with the relevant technology, and constantly improve their own strength and core competitiveness, and narrow the gap with developed countries. In the new market demand, update the sleeve pressing machine is a pressing matter of the moment. The production of pipe pressing machine equipment manufacturing enterprises to fully tap the potential of the market, vigorously develop the sleeves of large low cost pressing special machinery and equipment, plays a positive role in the evolution of automatic assembly, the assembly of mechanical equipment.
The overall plan is: the relative position of two axle sleeve on the plane, the motor reducer to provide power through belt drives the ew rod to rotate, and drives the head movement, a nut, a rotary motion of the linear motion of press. Block type safety clutch overload protection with teeth, pressure distribution in the corresponding position of the pipe after drilling through the drilling template.
Key words：pneumatic manipulator； cylinder； pneumatic loop； Fout degrees of freedom.
