一种刀具自动测量装置及方法

Device and method for automatically measuring cutter

Abstract

The invention relates to the technical field of cutter precision machining and measuring, in particular to a device and method for automatically measuring a cutter. The measuring method comprises the steps that before the cutter is measured, a measurer places the cutter to be detected into a V-shaped groove formed by a drive shaft and a driven shaft of the automatic detecting device, the position relation, relative to the cutter, of an optical measuring system composed of a CCD camera and a camera lens is adjusted through a manual two-dimensional adjusting platform, and after the adjustment, a manual Y shaft and a manual Z shaft are fixed through fastening screws; the measurer sets the moving parameters including the rotating speed, the steering direction, the rotation angles at intervals and the interval dwell time of the cutter when the measurement is carried out and sets the number of shot images through the optical measuring system at intervals and time for shooting each picture; after the parameters are set, the measuring system can be automatically generated. According to the device and method for automatically measuring the cutter, manual intervention is avoided in the measuring process, measuring precision is high, the measuring function is powerful, and the production scale is large.
一种刀具自动测量装置及方法,它涉及刀具精密加工及测量技术领域;它的测量方法为:刀具测量前,由测量员将待检刀具放置在自动测量装置的主动轴和从动轴构成的“V”形槽中;通过手动二维调整平台调节好由CCD相机及镜头构成的光学测量系统相对刀具的位置关系,调节好后,通过紧定螺钉固定手动Y轴和手动Z轴;测量员设置好测量时刀具转动速度、转动方向、每间隔转动角度及相邻间隔间的停顿时间的运动参数,并设置好光学测量系统在各间隔间拍摄图像的张数和每拍摄一张图片所需要的时间;设置好各参数后,测量系统便会自动生成;它具有测量过程中避免人工干预,测量精度高,测量功能强大,生产规模大。
