| 摘 要： | 直线导轨是数控技术的重要组成部件,它的精确程度非常重要。以MSP430单片机为核心,设计了一个直线导轨精确定位装置。此装置采用两相四线的ST57型步进电机和60CM的螺纹丝杆组成一个直线导轨组,选用M7128驱动器驱动步进电机,使用PWM波精确定位算法程序精确控制电机转速。MSP430的IO端口控制步进电机的正反转,使得步进电机带动螺纹丝杆转动,让滚动丝杠上的物体往复移动,并在电脑上显示当前位移值。试验证明,其定位精度为0.01cm,具有较高的可靠性和准确性,低成本,稳定性好。

| Abstract: | Linear guide rail is an important component of the numerical control technology which is very important to the degree of accuracy. With the core of MSP430 single chip microcomputer, a precise positioning device for linear guide rail is designed. The device adopts two phase four wire ST57 type step motor and 60CM screw thread rod to form a linear guide rail group which use M7128 driver to drive the stepper motor, using the program of PWM positioning algorithm to precisely control motor speed.MSP430 IO port control stepper motor positive inversion,making the stepper motor driven screw thread rod rotation, so that the object on the rolling screw to move back and forth, and the computer shows the value of the current displacement. Experiments show that the positioning accuracy is 0.01cm, which has high reliability and accuracy, low cost and good stability. |
