全液压并联式组合机构液动大钳的设计

Designing the giant hydraulic-actuated tongs with fullyhyraulic parallel type of combined mechanism

提出用全液压并联式组合机构设计液动大钳,该大钳是液压机构中的二杆系和四杆系的并联组合机构,可在最小外形尺寸下获得较大的力矩。同时采用不同的组合形式可得到不同的力矩。

This paper presents designning the hydraulic power tong with the aid of fully hydraulic parallel combination mechanisms. The are combination mechanisms of two bars and four bars in hydraulic mechanisms. In this case will acquire the bigger torques with the object of smallest sizes,in addition are applyed different forms of combinations with a view to acquire different torques.
