摘　　要：气压传动由于其高效率、低成本和对环境没有污染,在制造业中,特别是在压力机中得到了广泛应用.但是,气动压力机有一个致命的缺点,就是气体极易泄漏,导致系统压力不能太高.因此,如何增加压力机的输出力及优化输出性能是设计者要解决的主要问题之一.针对一些传统压力机的不足,作者利用自行创新的方法——高副取代低副法,设计了将滑动副变为滚动副的基于无杆活塞缸与增力机构toggle的气动压力机.所提出的创新设计理念,可以使设计人员遵循一定的思维程序,仅仅通过改变增力机构toggle与无杆活塞缸的数量、联接模式和配置方式,就可重构出不同结构与性能的气动压力机,满足生产过程中对压力机布局、多工位、大输出力和变输出力的需求.同时提供了一些创新设计案例,给出了相应的简明力学计算公式,并对力学性能进行了对比.The machines driven by pneumatic are widely used in manufacturing industry, especially in press machines, because of their high efficiency, low cost and no pollution to environment. However, pneumatic press machines generally only work in lower pressure clue to the leak of air. It is this critical disadvantage that makes their application limited. Therefore, the primary problem confronting designers is how to increase output force and output performance of pneumatic press machine. The creative design idea presented enables designer to follow some thinking procedure and reconstruct pneumatic press machines with different structure and different function by merely changing connection forms, amount and configuration between cylinder with rod-less piston and force amplifier toggle to satisfy the requirements of configurable layout of press machines, mult-positioned, large output force and varying output force in producing process. Some innovative design illustrations are presented as well as their simplified calculating formula and performance analysis.
