摘要传统的外圆磨床在线测量系统比较落后测量效率不高,外圆磨床上加工的回转体内外直径多数依靠人力检测完成,检测效率低下。为了解决这一现状,本文介绍了外圈磨床中外圆直径在线检测系统设计。用与系统相匹配的外径测量传感器定位到贯穿式外圆磨床上直接进行高效的、直接的测量,实现轴承套圈在加工过程中完成检测,通过PLC、触摸屏、传感器以及控制器形成完整的在线检测系统对外圆直径进行有效的测量、统计和结果显示。34821
系统采用的主动量仪对外圈直径在线检测,具有测量精确、与数控机床连接定位方便的特点。为了方便地确定轴承套圈的直径,在传感器测头测子上设置平行滑杆,使轴承套圈夹在其中间,得到外圆直径。通过PLC控制系统控制伺服电机,继而控制外圆磨床的进给,由此得到带有反馈的外圆磨削闭环加工系统,具有效率高、精度高的特点。 毕业论文关键词:轴承套圈、在线测量、PLC系统、外圆磨床、传感器
Abstract
The on-line measuring system of the traditional cylindrical grinder is not efficient, the external diameter of the cylindrical grinder is mostly dependent on human detection, and the detection efficiency is low. In order to solve this problem, the on-line detection system of the circular diameter of the outer ring grinder is introduced. And system matching the outer diameter measuring sensor positioning to through external circular grinding machine directly efficient, direct measurement, the realization of bearing rings in the process to complete the test. By PLC, touch screen, sensor and controller to form effective measurement, statistical analysis and result display complete online detection system of the diameter of a circle.
The system uses the initiative measuring instrument for measuring the diameter of the outer ring, which has the characteristics of accurate measurement, convenient connection with the numerical control machine tool. To easily determine the diameter of the bearing rings, in sensor measuring arranged on parallel slide bar, bearing ring caught in the middle, outer diameter. Through the PLC control system control servo motor, and then control the feed of the cylindrical grinder, the closed-loop machining system with feedback is obtained, with the characteristics of high efficiency and high accuracy.
