重卡轮毂轴承总成轴肩及内径尺寸检测机控制系统设计

针对目前国内重型卡车(简称重卡)轮毂轴承总成检测设备尚未成熟,人工检测精度不高、效率低下等问题,详细阐述了重卡轮毂轴承总成轴肩及内径尺寸检测机的主要结构、关键检测位置等重要组成部分,并从主要检测工艺流程出发,设计了一款适合该检测机的控制系统,重点设计了该控制系统的硬件、软件部分,并对控制系统的关键部分进行布线组装;应用该检测机进行在线自动检测。从调试检测结果发现,该控制系统运行稳定,能够准确根据设置的标准参数检测到重卡轮毂轴承总成轴肩宽度及轴承安装孔内径尺寸,并且判断工件尺寸是否合格,验证了该控制系统设计的可行性。该检测机目前已在企业的智能装配线中使用,基本满足企业自动化生产要求。

Design of control system for shoulder and inner diameter measuring machine of heavy truck hub bearing assembly

In view of the fact that the domestic heavy truck hub bearing assembly testing equipment is not yet mature,the manual detection accuracy is not high,the efficiency is low,the main components of the heavy truck hub bearing assembly shoulder and inner diameter size detector,key detection positions and other important components are elaborated.And from the main inspection process,designed a control system suitable for the measuring machine,focus on the hardware and software parts of the control system,and wired assembly for the key parts of the control system.Finally,the measuring machine automatically detected online.From the debugging test results,the control system was stable and can accurately detect the shoulder and inner diameter of the heavy truck hub bearing assembly according to the set standard parameters,and can judge whether the workpiece size is qualified or not.The designed feasibility of the control system was verified.The measuring machine has been currently used in the company s intelligent assembly line,which basically meets the requirements of enterprise automation production.
