气动肌腱驱动的肘杆-杠杆增力双工位并行高效夹紧装置

Double-Position Highly-Efficient Parallel Clamping Device Based on Toggle-Lever Force Amplifier Driven by Pneumatic Muscle

创新设计了一种由气动肌腱驱动的基于肘杆和恒增力杠杆的角度和长度力放大效应的双工位高效夹具。该机构用结构极为简单、柔性好、输出力与直径比大、输出力与重量比高的气动肌腱来代替传统的刚性气缸,通过与传统气缸驱动方式相比较,发现其夹紧效果更显著,系统结构更紧凑,同时符合绿色节能新理念,值得推广。

In this paper, a type of double-position and highly-efficient clamping device which is driven by pneumatic muscle based on the angle and length force amplification effect of toggle and the eternal lever force amplifier is described. The pneu-matic muscle which takes place of the traditional rigid cylinder has some features such as extremely simple structure, good flexibility, larger ratio of the output force and diameter/weight, etc. By comparing with the traditional system, the system driven by pneumatic muscle has greater clamping force and more compact structure. Meanwhile, it is a green and energy-sav-ing system, so it deserves to be promoted.
