针对异形元器件的插装问题,设计了一种可以稳定插装异形元器件的插件头.首先,将滚珠丝杆副传动系统应用于插件头升降机构的设计,并且通过理论计算进行伺服电机的选型.然后,利用ADAMS运动仿真软件模拟插件头的升降运动和旋转运动,验证计算结果的可靠性以及结构的稳定性.最后,将插件头安装在异形插件机上进行插件试验,利用NYCe运动控制系统测量得到插件运动过程中的相关数据.试验结果表明:插件头的升降运动的最大速度接近1m/s、单程运动时间在 0.012 s以内,满足设计要求;在仿真运动过程中,旋转机构夹爪质心的位移变化保持在±0.015 mm以内,表明旋转运动比较平稳,精度符合插件工作要求.试验结果验证了插件头的实用性.该研究为后续优化插件头的性能、提升插件效率提供依据.
Aiming at the problem of insertion and assembly of shaped components,a kind of insertion head that can stably insert and assemble shaped components is designed.Firstly,the ball screw sub drive system is applied to the design of the insertion head lifting mechanism,and the servo motor is selected through theoretical calculation.Then,ADAMS motion simulation software is used to simulate the lifting and rotating motion of the insertion head to verify the reliability of the calculation results and the stability of the structure.Finally,the insertion head is installed in the shaped insertion machine for the insertion test,the relevant data in the process of insertion movement is measured by NYCe motion control system.The test results show that:the maximum speed of the lifting movement of the insertion head is close to 1 m/s,and the one-way movement time is within 0.012 s,which meets the design requirements;the displacement change of the clamping jaw center of the rotating mechanism in the simulated movement process is kept within±0.015 mm,which indicates that the rotary movement is relatively smooth,and the accuracy is in line with the insertion requirements.The test results verifies the utility of the insertion head.The study provide a basis for the subsequent optimization of the performance of the insertion head and enhance the insertion efficiency.
