基于高速凸轮机构的PTM机组电动冲击器设计（本科毕业论文设计）
摘 要
本次设计主要是针对电解铝厂的实际生产而选题的。铝电解槽的加工主要是铝电解多功能天车（PTM）完成的。其中包括对所结碳化壳面的击碎，以保证铝电解过程的顺利进行。目前国内外PTM天车只有两种：液压和气动。由于环境特殊，对液压和气动系统要求较高，价格也相对昂贵，本次设计主要是以电动的形式来设计冲击器，要求能设计出一种造价低，结构简单，维修方便的冲击器来取代目前的产品。如此则可以大大节省工厂设备的费用，降低成本，提高经济效益有极其重要的意义。
能够实现冲击功能的方案较多。这次设计主要是用弹簧提升锤头，弹簧被压缩，然后锤头在弹簧力和重力的合力下，实现冲击功能的。在这次设计过程中，主要进行了机械运动方案设计，机构的运动和动力分析，动力计算，电动机的选择及整套装置的结构设计，从而实现了电动机驱动的冲击装置的设计。

ABSTRACT
The subject of design is proposed for the actual produce that most aluminum factories face. The manufacture of aluminum electrolytic tank is finished by overhead traveling crane(PTM crane). It includes striking the surface of aluminum going on. At present, there are only two types impacting equipments on PTM crane at home and abroad: hydraulic pressure and air-powered. Because the circumstance is very particular,, it highly requires impinger of hydraulic pressure or air-powered. And the price is very expensive. The design is mainly to design a impinger which is in the form of electric drive. It is required to design a cheap and simple structure impinger which is in the form of electric drive to instead of the production at the moment. Thus, it can save much expense for equipments, reduce the cost and there are very important meanings to improve the economic efficiency.
There are many plans to achieve the impacting functions. This design mainly use cams o lift the hammer, condense the spring, then the hammer achieve the impacting functions by the resultant force of elastic fore and gravity. To the design, I have finished the design of scheme to mechanical movement, the analysis of mechanisms movements and motive power, motive powers calculation, the choice of electric motor and structural design of all devices.
Key words: aluminum electrolytic tank, PTM crane, electric motor, impinger, impact
