摘要

凸轮轴是发动机的重要部件之一,对其准确测量和误差评定一直是精密测量领域研究的重点。全面介绍了当前凸轮轴几何量测量技术的研究现状及基于各种测量原理的专用仪器,其中高精度、多功能立式凸轮轴测量仪仍是目前的主流设备,光学非接触式测量方法和仪器测量效率高,具有良好的发展前景。分析了凸轮测量数据处理和误差评定一些关键的技术方法,每种方法各有利弊,仍需研究更加科学的处理方法。提出了一种基于激光干涉测量原理的凸轮测量方法,激光干涉测长可以直接溯源到长度基准“米”,可以从根本上提高凸轮的测量精度。各种凸轮轴测量仪器的量值校准及统一是未来计量工作的研究重点,JJF 1795-2020《凸轮轴测量仪校准规范》的发布和实施为仪器的校准检测提供了统一的参考方法,而关于软件算法的评定研究,目前国内还处于空白状态,亟需开展相关的研究工作。

Abstract

The camshaft is one of the important parts of the engine, and its accurate measurement and error evaluation has always been the research focus of precision measurement. The current research status of camshaft geometry measurement technology and the specific instruments based on various measuring principles were introduced comprehensively. At present, the vertical camshaft measuring instruments with high accurate and multi-function are popular applied, and the optical non-contact measuring methods and instruments have a great prospect for development because of high measuring efficiency. Some key technical methods applied in cam measurement data processing and error evaluation are analyzed. Each method has advantages and disadvantages. Therefore, more suitable methods still need to be studied. A cam measuring method based on the principle of laser interferometry is proposed. The laser interference length measurement can be directly traced to the length reference “m”, which can improve the measurement accuracy of the cam. The calibration and unification of various camshaft measuring instruments are of importance in future. The JJF 1795-2020 Calibration specification for camshaft measuring instruments is released and implemented, which provides a unified reference method for the calibration and inspection of instruments. However, the evaluation for software algorithm is still currently lacked in domestic, so it is urgent to carry out relevant research work.
