摘要：

基于销合链链板多工位冲压自动化加工平台，对其自动送料系统的运动可靠性展开研究。首先，依据实际工况，对自动送料系统的动作需求进行分析，并完成各运动部件的运动规划及动作时序的划分。然后，基于ADAMS软件建立自动送料系统的仿真模型，设置好仿真参数和各运动的驱动约束函数，通过运动仿真获得各构件的位移、受力和力矩的变化曲线；对自动送料系统的末端执行机构的水平、竖直方向的速度与加速度进行分析。最后，在完成控制系统设计的基础上，搭建了销合链链板多工位冲压自动化加工平台样机，并进行实验验证。实验结果表明：销合链链板多工位自动冲压的生产效率可以达到6~7 件·min-1，满足销合链链板生产节拍≤10 s/件的要求。

Based on the multi-station stamping automation processing platform of pin-joint chain plate, the movement reliability of its automatic feeding system was studied. First of all, according to the actual working conditions, the motion requirements of the automatic feeding system was analyzed, and the motion planning of each moving part and the division of action sequence were completed. Then, based on software ADAMS, a simulation model of the automatic feeding system was established, the simulation parameters and the driving constraint function of each movement were set up, and the change curves of displacement, force and torque for each component were obtained through motion simulation. Furthermore, the velocity and acceleration of end effector for the automatic feeding system in the horizontal and vertical directions were analyzed. Finally, on the basis of completing the control system design, a prototype of the multi-station stamping automation processing platform for the pin-joint chain plate was built, and the experimental verification was carried out. The experimental results show that the production efficiency of multi-station automatic stamping for pin-joint chain plate can reach 6-7 pieces per minute, which meets the requirement that the production cycle of pin-joint chain plate is less than ten seconds per piece.
