一、概述用单位增量脉冲计数的方法,对大直径(内径或外径)转动件进行电测的基本原理如图1所示: 在进行大直径加工时(图1划出了加工外径的情况)测量轮被工件所驱动,经增速器带动自整角发送机转动,自整角接收机与其同步转动进而带动光码盘转动。光码盘旁的光敏器件感知光码盘的转动,并发出测量脉冲。工件与卡盘一起转动,而固定在卡盘上的拨杆,每当
First, an overview Incremental pulse counting method with units, the large diameter (diameter or diameter) of the rotating electrical measurement of the basic principles shown in Figure 1: In the large diameter machining (Figure 1 out of the processing diameter ) The measuring wheel is driven by the workpiece. After the speed-increasing device drives the self-alignment angle transmitter to rotate, the self-alignment angle receiver rotates synchronously with it to drive the optical code disk to rotate. The light-sensitive device next to the optical codepad senses the rotation of the optical codepad and emits a measurement pulse. The workpiece rotates with the chuck, while the lever fixed on the chuck, whenever
