加工中心机械手换刀与主轴凸轮松刀的联动技术

摘要

加工中心机床主轴的双凸轮联动换刀是利用电动机驱动松刀凸轮,实现主轴的松刀动作的同时带动链条传动给机械手换刀凸轮,实现换刀动作,从而使松、换刀同时完成,提高了换刀时间.%There is a kind of changing tool with double-cam linkage applied to spindle of the horizontal machining center, and the cams are driven by motor. Spindle loosening-tool can drive chains to manipulator changing tool, this structure makes the two actions being completed at the same time and shorten the time for changing tool.
