Lead screw detection device and method

The invention relates to the technical field of precision measurement, in particular to a lead screw detection device and method. According to the lead screw detection device and method, the lead screw is rotated through the servo motor to drive the lead screw nut to move, the magnetic induction switch enables the lead screw nut to obtain reciprocating linear motion, the CNC actual lead screw use condition can be simulated by writing different programs and assembling workpieces with set loads, and required data are measured and judged by other devices such asthe laser interferometer,a reflector and the like. 本发明涉及精密测量技术领域，特别是涉及一种丝杆检测装置及方法。本发明提供了一种丝杆检测装置及方法，通过伺服电机旋转丝杆带动丝杆螺母运动，配上磁性感应开关使丝杆螺母获得往复直线运动，可通过写入不同程序，装配设定负重的工件去模拟CNC实际丝杆使用情况，利用激光干涉仪，反射镜等其它设备去测量所需数据并进行判定。
