摘要
以自动化连线的伺服压力机的六连杆机构作为研究对象,在建立六连杆机构的运动学模型的基础上,结合工程实际设定约束条件,针对滑块行程、滑块速度、滑块加速度为优化目标。通过优化设计,滑块具备较大的工作行程和慢进急回的运动特性,便于自动化连线中机械臂抓放工件,并且滑块在工作行程区间内速度较低且变化平缓,最大加速度阶段在整个冲压周期内时间更短。
The six-link mechanism of the servo press with automated linkage is taken as the object of study,and on the basis of establishing the kinematic model of the six-link mechanism,the constraints are set in conjunction with the engineering reality,and the optimization objectives are the slider stroke,slider speed and slider acceleration.Through the optimization design,the slider has a larger working stroke and slow forward and backward motion characteristics,which is convenient for the robotic arm to grasp and place the workpiece in the automation line,and the slider has a lower speed and gentle change in the working stroke interval,and the maximum acceleration stage is shorter in the whole stamping cycle.
