Abstract: This design focuses on the development of a high-precision positioning system based on ball screw. The system uses a stepper motor to drive the ball screw for positioning, with the advantages of high precision, fast speed, quietness, and long service life. The design mainly involves the selection of ball screws, the drive of stepper motors, the selection and installation of sensors, and the design of control systems. Through experimental verification, the system has high positioning accuracy and stability, and can be used in various occasions that require high-precision positioning.

5. 确定滚珠丝杠长度:根据所需行程长度选择适合的滚珠丝杠长度,
2. P3精度等级:滚珠丝杠的轴向游隙为P3级别,具有更高的精度和更小的轴向游隙,
3. C5级:精度较高,适用于需要高精度的机械设备,如精密仪器、数控机床等,导程是指每个螺纹的螺距和间距之比,也就是每圈螺纹上的移动距离,
2. 定位精度:滚珠丝杠具有高精度的传动性能,能够实现精确的定位控制,一般来说,导程高度越高,滚珠丝杠的线速度就越快,但是也会增加滚珠丝杠的摩擦和磨损,滚珠丝杠机构具有高效率、高精度、高刚度等特点,可用于传递转矩和线性运动,丝杠是一个螺旋线形的轴向元件,螺纹的外径与滚珠直径相等, 5. 在拆卸过程中,可以适当地添加滑动油来减少摩擦力,方便拆卸
