摘要
创新设计了两种夹紧装置,以结构极为简单、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,并采用恒增力杠杆机构进行力放大,能在大幅度降低结构体积与重量的前提下,得到较大的夹紧力。此外,采用两个气动肌腱交替作用,可使一个工件的装卸时间与另一个工件的加工时间重合,因而显著提高了生产效率。
Two new innovation design ideas of clamping mechanism based on pneumatic muscle and the eternal lever force amplifier is described in this paper,in which the pneumatic muscle is instead of traditional rigid cylinder. The pneumatic muscle has some features such as extremely simple structure,good flexibility,the big ratio of output force and diameter/weight,etc. Thus,this device can get much greater clamping force on the condition of reducing the size and weight of the structure definitely. In addition,using two pneumatic muscles alternately,it can enable the time of processing a workpiece to overlap with the time of unloading another workpiece,and which can improve the production efficiency significantly.
