摘要
传统电主轴采用恒速转动水冷机进行热变形抑制,其运行功率与机床工作状况无关,难以反映机床的实时运行状况,且实时性不高,难以满足高速高精度生产需求,为此提出一种电主轴温度采集-水冷机模块-数控系统相结合的热误差主动抑制方法。首先提出了整体设计方案,接着完成了电主轴温度采集模块、水冷机模块及与数控系统通信模块的开发,然后基于华中数控PLC开发了水冷机数控PID控制模块,最后基于华中数控系统开发了热误差主动抑制系统,进行了系统测试与验证。相关测试表明,所研制的温度采集模块和水冷机数控PID控制模块具有较高的稳定性和可靠性,对于立式加工中心电主轴热误差主动抑制起到了较好成效,具有良好的工程应用价值。
The traditional electric spindle adopts a constant speed rotating water cooler to suppress thermal deformation,and its operating power has nothing to do with the working condition of the machine tool,which is difficult to reflect the real-time operation status of the machine tool,and the real-time performance is not high,and it is difficult to meet the needs of high-speed and high-precision production.Firstly,the overall design scheme was proposed,then the development of the electric spindle temperature acquisition module,the water cooler module and the communication module with the CNC system was completed,then the CNC PID control module of the water cooler was developed based on the Huazhong CNC PLC,and finally the thermal error active suppression system was developed based on the Huazhong CNC system,and the system was tested and verified.The relevant tests show that the temperature acquisition module and the numerical control PID control module of the water-cooled machine have high stability and reliability,and play a good role in the active suppression of the thermal error of the electric spindle of the vertical machining center,and have good engineering application value.
