一种新型断线钳的运动分析

Kinematics Analysis of a New Bolt Cutter

长臂绝缘断线钳是电工户外作业经常用到的工具。断线钳多采用曲柄滑块结构,操作较为笨重,因此对其改进优化很有必要。文章介绍了一种采用曲柄滑块和四连杆机构相结合的新型断线钳,对常规与新型两种断线钳分别建立三维模型,并进行运动分析,指出其优点及缺点。

Long arm insulated wire cutting pliers are often used by electricians in outdoor operation. The cutting clamp adopts the crank slider structure and the operation is more heavy. Therefore, it is necessary to improve and opumize. This paper introduced a new type of wire cutter with a combination of crank slider and four bar linkage. Three dimensional models of two kinds of broken nippers were built respectively. Their motion analysis was carried out, and their advantages and disadvantages were pointed out.
