在滚珠丝杠的两端通常需要堵头，以保证滚珠不会从滚珠丝杠的两端滑出, 9. 在螺母的螺纹上画出一条线，代表滚珠丝杠的轴,滚珠丝杠模组通常由以下几个部分组成： 1. 滚珠丝杠：将旋转运动转换为线性运动，由螺纹轴和螺母组成，其中螺纹轴上镶嵌有一定数量的滚珠，滚珠在螺纹轴和螺母之间滚动，从而实现线性运动, 关键词：滚珠丝杠；步进电机；定位系统；控制系统；传感器 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. Keywords: ball screw; stepper motor; positioning system; control system; sensor, 2. 重庆凯立德轴承有限公司：该公司成立于2008年，是一家专业从事滚珠丝杠轴承和直线导轨的生产和销售的企业, 2. 高速度：由于滚珠滚动的特性，滚珠丝杠与导轨的配合可以实现高速运动,同时，上下结构也便于维护和更换滚珠组和螺母组,在机械制造、自动化设备、数控机床等领域广泛应用, 6. 高载型：这种滚珠丝杠采用更加坚固的设计和材料，具有更高的承载能力，适用于要求较高承载能力的设备, 7. 拆下滚珠丝杠上的滚珠保持器
