在机械制造中,特别是在工具制造中,我们时常要测量各孔间的距离。通过孔距的测量,还可以校验孔的等分情况和是否在同一节圆上。现在就来谈谈最常用的几种测量孔距的方法:(一)用游标卡尺或量块和量块夹进行测量1)使用方法的选择:游标卡尺本身的读数较粗,测量误差较大,所以用游标卡尺测量的精度较差,而用量块和量块夹来测量,精度就比较好。在工作时,要按照具体设备条件和工件精度要求来决定。
In machine construction, especially in tool making, we often measure the distance between holes. Through the measurement of the hole distance, you can also check whether the holes are equally divided and on the same pitch circle. Now to talk about the most commonly used method of measuring the hole distance: (a) with vernier caliper or measuring block and the amount of clip measurement 1) the use of the method of choice: Vernier caliper itself, the readings are coarse, the measurement error is large, so The accuracy of the measurement with vernier caliper is poor, while the amount of measuring block and measuring clip, the accuracy is better. At work, according to the specific equipment conditions and workpiece accuracy requirements to decide.
