镗床多功能刀架设计

摘要

针对没有平旋盘的镗床在加工过程中无法调整镗刀的径向进给量问题,通过对径向进刀系统传动链的运动分析和计算,设计一种镗床多功能刀架.使用该刀架能在主轴旋转的同时,手动或自动调节镗刀的径向进给量.并采用Pro/E软件建立了刀架的三维模型.使用该刀架能极大地方便加工操作,提高机床的加工效率.%Aiming at the question that the radial feed rate unable adjusted during processing of boring mills without flat spin dish, on the basis of analyzing and calculating the movement of the drive chain of radial feeding system, a multifunctional tool rest was designed with which the radial feed rate of a boring cutter could be adjusted manually or automatically while the main axis was rotating. By using the Pro/E software, the three-dimension model was built. By this method, the operation process and machining efficiency of the machine tool are improved substantially.
