摘要
回零过程是注射成型机在正式生产之前确立各运动部件相互位置关系的重要工艺步骤,是后续生产过程的基础。针对全电动注射机运动部件的精确定位与控制需求,考虑各运动机构需要回零的两种工况,提出基于回零技术的全电动注射机位置系统的回零方法,对其进行机械零点的定义,在此基础上完成回零算法设计,在Linux操作系统环境下,基于华中数控HNC-8开放式数控平台开发了回零控制程序。经过试验测试回零精度,结果表明,各运动机构的回零平均误差小于位置控制精度设计要求的0.01 mm,各运动部件能够准确回到初始状态。
The returning home process is an important technological step for injection molding machine to establish the positions relationship among each moving part before injection production and is the basis of the subsequent injection molding process.Aiming at the precise positioning and control requirements of the moving parts of all-electric injection machine and considering the two working conditions in which each moving mechanism needs to return to zero point,this paper proposed a returning home method of the position system of all-electric injection machine based on the returning home technology.Based on the definition of mechanical zero of machine,the returning home algorithm was designed.The control programs,which were developed in Linux operating system and Huazhong CNC(computer numerical control)system platform HNC-8 were integrated with the mechanism of an injection molding machine.Finally,an experiment was performed to verify the accuracy of the proposed returning home algorithm.The results show that the average position error of returning home of each moving mechanism is less than the design requirements of 0.01 mm for position control precision and each moving part was able to accurately return to the initial state.
