提出了基于霍耳传感器获取主轴的转数信号,与工序控制单元、电磁离合器与曲柄滑块机构单元、电磁铁推杆系统通断进出油缸的路径以及节流路径定位时自行关闭相组合的设计方案。研究了油的汽化压和电器时间常数与主轴极限转速的关系。
A design based on Hall sensor to obtain spindle’s revolution signal, combined with process control unit, electromagnetic clutch and crank-slider mechanism unit, electromagnet push-rod system on-off and on-off cylinder and self-closing of throttling path was proposed Program. The relationship between the vaporization pressure of oil and the time constant of the motor and the speed limit of the spindle was studied.
