Design of Automatic Spindle Straightness Measurement and Adjustment Device

摘要:

轴类工件的直线度调整方法需要调直和检测功能相互配合完成,一般需要两套设备或装置。通过设计一种基于DSP主控芯片技术的智能化测量调直装置,实现一台设备同步完成调直和检测。该设备设有检测工位和调直工位,工位可自动切换,设备可根据对轴类件直线度指标的检测结果,自行判断合格情况并对不满足设计要求的工件进行调直处理,直至其直线度合格。以DSP芯片为核心的嵌入式开发包,实现对激光传感器、压力传感器及电气执行单元的集成控制。软件采用CCS3.3开发环境,通过开发调直下压量自反馈机制和圆周跳动测量数据拟合程序,解决设备实现自动闭环控制的关键技术难题。调直检测实验结果表明,该设备可实现对轴类工件的全闭环智能自动检测及调直,直线度指标圆周跳动量小于0.05mm,可大幅减提高轴类工件的直线度水平。

Abstract:

Spindle need to adjust their straightness by straightening and detecting equipments. By designing an intelligent measurement and straightening device based on DSP master chip technology, a device can be synchronized to complete the straightening and detection. The equipment is equipped with testing station and straightening station, which can be switched each other automatically. The device is equipped with a test station and a straightening station, which can be switched automatically. The device can automatically straighten the spindle according to the test results until its straightness is qualified. Embedded development package with DSP chip as its core enables integrated control of laser sensors, pressure sensors and electrical execution units. The software adopts the CCS3.3 development environment, and solves the key technical problems of automatic closed-loop control by developing the direct pressure self-feedback mechanism and the circular run-up measurement data fitting program. The results of the straightening test show that the device can realize the automatic detection and straightening of the closed-loop workpiece, and the linearity shape tolerance is less than 0.05mm, which greatly improves the straightness of the spindle.
