采用平面连杆机构实现小型冲压平板件的自动送料 ,可实现较大的送料行程。由于连杆机构的运动副较多 ,致使冲压件的送料精度不易得到保证。本文采用可视化方法对送料机构的位置误差进行分析 ,找出影响位置精度的主要因素 ,采取相应措施以保证冲压件的送料精度。 Adopting the plane connecting rod mechanism to realize the automatic feeding of the small pressing flat plate parts, the large feeding travel can be realized. As the linkage rod movement more, resulting in stamping parts feeding accuracy is not easy to be guaranteed. In this paper, the visualization method is used to analyze the position error of the feeding mechanism to find out the main factors affecting the position accuracy and take corresponding measures to ensure the feeding accuracy of the stamping parts.
