基于虚拟凸轮技术的两轴协调运动研究

Two-Axises Coordination Motion Based on Cam Mechanism

提出一种基于虚拟凸轮技术控制两轴协调运动,进而实现二维精确定位的方法.该方法首先在S7-Technology软件下组态主轴、从轴以及其对应的虚拟凸轮盘,通过控制凸轮盘来实现轴与轴之间的协同运动,从而实现二维精确定位.控制部分与驱动部分的通信采用Profibus DP总线协议.实验表明:设定轨迹与实际运动轨迹之间同步性好,机械控制误差<0.5,mm,符合精确定位的要求.

A two-axises coordinated motion based on virtual cam was developed to fulfill precise positioning of two-dimensional.The S7-Technology was used to configure the axis and the cam plates corresponding to the axis,by controling the cam plate the coordination between two axises was achieved so as to fulfill precise positioning of two-dimensional.Profibus DP was used to connect the control section and the drive section.Results show that the settings coincide with the actual value.Mechanical error is less than 0.5 mm and meets the requirements of precise positioning.
