一、前言精度要求较高的锥体制件的锥角,一般采用锥度测量仪进行正确测量。但一般工厂中很少具备这种仪器。在生产实践中,为了克服这一困难,满足生产需要,我们利用普通正弦规,配上一套附加装置,对可以安放在正弦规上的锥体制件的锥角进行测量。将近二年来的实践证明,此种附加装置的测量结果,精度比较高,操作和制造亦很方便。 First, the foreword The pyramidal angle of the conical parts that require higher precision, generally adopt the taper measuring instrument to carry on the correct measurement. However, this type of instrument is rarely found in general factories. In production practice, in order to overcome this difficulty and to meet the production needs, we used the common sine gauge with an additional set of attachments to measure the taper angle of the cone parts that can be placed on the sine gauge. Nearly two years of practice have proved that such additional device measurement results, high accuracy, operation and manufacturing is also very convenient.
