基于变频技术的电刷镀机床开发

Development of Electric Brush-plating Machine Tool Based on Inverter

电刷镀技术在轴类零件的表面强化、修复并恢复尺寸精度等工艺中应用十分有效。轴类零件的电刷镀工艺要求机床主轴能实现无级变速。基于变频调速技术,实现电刷镀机床主轴的无级变速控制;应用电气控制系统的设计,实现机床启动、停止、调速、状态显示以及运行保护等功能的自动控制,从而提高电刷镀机床的生产效率和自动化程度。该设备已在天津工程机械研究院的"平地机关键零部件的再制造技术及其产业化"这一科研项目中得到成功应用。

Electric brush - plating is very useful in surface strengthen and redemption for shaft. The spindle of electric brush - plating machine tool should be infinitely variable speed. On the basis of frequency control, the infinitely variable speeds control for machine tool spindle is realized. Through the designing of elec- tric control system, the functions such as start, stop, speed control, status display and protection are realized automatically. The atomization and productivity effect are increased remarkably. This electric brush - plating machine tool has been applied successfully in the project of Re - manufacture Technique and Its Industrialization of Motor Grader Key Parts in Tianjin Research Institute of Construction Machinery.
