在我们生产实践中,常常要遇到加工轴类零件,轴类零件因传递动力需要,一般要加工键槽,键槽因对称度要求,无论是加工还是测量都比较麻烦,本篇着重介绍键槽对称度测量。我们知道若轴类零件直径较小,可以用游标卡尺直接测量,若直径较大就必须在检验台用 V 型块支撑,用量块、百分表进行测量。但我们经常遇到大的轴类零件,如我厂生产的轻型钻机主滚筒轴最人直径为φ200,长2848重量6499.6kg,轴上加工8对键槽,就需要配备专门检验平台,而且测
In our production practice, we often encounter processing shaft parts, shaft parts due to the transmission of power needs, generally to be processed keyway, keyway symmetry requirements, whether it is processing or measurement are too much trouble, this article focuses on keyway symmetry measuring. We know that if the diameter of shaft parts is small, you can use the vernier caliper to measure directly. If the diameter is larger, you must use the V-block to support the test bench, the measuring block and the dial indicator. However, we often encounter large shaft parts, such as the light drum rig I produced the most diameter of the main shaft φ200, long 2848 weight 6499.6kg, the shaft 8 keyway processing, you need to be equipped with a special inspection platform, and testing
