摘要

自动化冲压生产中,冲压机器人通过执行机构完成工件的夹取和输送,执行机构定位由电气控制和挡块的相互配合完成。挡块进行辅助定位时,执行机构会与挡块发生碰撞,这对冲压生产产生了不利的影响,故对执行机构进行碰撞仿真分析及结构优化设计。利用UG NX8. 5软件建立执行机构的三维实体模型,并导入Abaqus软件进行有限元仿真分析,获得工件的夹持力、加速度和倾斜角度等参数。由仿真结果分析可知,工件受到的夹持力为零及峰值较大的情况较多,工件的加速度在短时间内剧烈变化,碰撞后倾斜角度偏大。针对以上问题对执行机构进行优化设计,有效地减小了碰撞对执行机构产生的影响,提高了冲压生产的效率。

Abstract

In the automatic stamping production,the stamping robot completes the clamping and conveying of workpiece through the actuator,and the positioning of the actuator is completed by the mutual cooperation of electrical control and stopper.During the auxiliary positioning of the stopper,the actuator will collide with the stopper,which has an adverse impact on the stamping production. Therefore,the impact simulation analysis and structural optimization design of the actuator are carried out.The 3 D solid model of the actuator was established by UG NX8. 5 software,and imported into ABAQUS software for fem simulative analysis to obtain the clamping force,acceleration and tilt angle and other parameters of the workpiece. From the analysis of simulation results,it can be seen that the clamping force on the workpiece is zero and the peak value is large,the acceleration of the workpiece changes sharply in a short time,and the tilt Angle after collision is large. Aiming at the above problems,the optimal design of the actuator is carried out,which effectively reduces the impact of collision on the actuator and improves the efficiency of stamping production.
