摘要
为解决传统剪刀的螺栓紧固结构在换刀及间隙调整方面存在的弊端,本文依据圆偏心机构夹紧原理,以电动修枝剪刀为设计对象,通过对夹紧机理、机构设计进行研究分析,设计出一种适用于修枝剪刀动、定刀快速定位及换刀的圆偏心夹紧换刀机构。该机构能有效解决普通剪刀在修剪作业过程中螺栓松懈后再次夹紧困难、换刀程序繁琐等问题,从而提高作业时夹紧、换刀的速度。本文对设计步骤及计算方法进行了详细的描述,为电动、气动、液压等机械化修枝剪的紧固换刀装置设计提供理论参考依据。
Pruning shears have been widely used in the garden shaping and orchard pruning.In recent years,various types of pruners have been developed both at home and abroad.However,the traditional bolt and nut structure is still used in the clamping structure of the vertical tip.When it is working,the traditional structure presents the following problems：the clamping structure is easy to loosen and it is difficult to clamp again without auxiliary tools after slackness;after long time operation,it is complex to replace the blades and an auxiliary tool is in need,which reduces the operating efficiency.Based to the clamping principle of the circular eccentric mechanism,a circular eccentric clamping ATC is designed,which is suitable for pruners to clamp in the vertical tip.Circular eccentric clamping ATC can effectively solve the above problems.This paper also studies the mechanism of the clamping process and mechanical design to determine the optimum dimensions.
