摘要
设计了一种新型可用于机器人制孔系统的螺旋铣孔末端执行器,该末端执行器通过直线调偏方式调偏,并采用双螺母结构消隙,相较于双偏心结构简单直接。详细介绍了该末端执行器抱紧机构设计方案,采用楔形结构抱紧以增大作用面积、提升抱紧效果。并通过对该末端执行器进行运动仿真分析,得出其在工作条件下影响刀尖轨迹包络直径的因素及排列顺序,对包络直径影响的因子按主次排列,其顺序依次是偏心距、自转速度、公转速度。
A new type of helical milling hole machining end effector which could be conveniently applied in robotic hole machining system was desinged. The radial adjusting mechanism was used in the effector. By means of the linear method,the radial adjusting mechanism adjusted offset distance and used double nuts to erase backlash. Compared with the double-eccentric structure,the radial adjusting mechanism was simple and direct. Then,the design method of the hold mechanism that adopted the wedge structure was introduced in detail,and the wedge structure was used to increase function area and improve effect to hold inner structure. Finally,through the motion simulation analysis,it’s concluded that the factors affecting the envelope diameter of the trajectory of the lathe tool under operating conditions in order are the offset distance,the rotation speed,and the revolution speed.
