,具体涉及一种用于测量石墨电极接头圆锥外螺纹的专用测量环规。
技术介绍
随着对石墨电极产品质量要求的逐步提高,生产厂商需要对石墨电极的各项指标进行详细检测,检测对象中包括有连接在石墨电极端部的接头。其中,对石墨电极接头圆锥外螺纹的检测非常重要,而圆锥外螺纹的检测主要是针对锥度和中径进行检测。目前,炭素企业中广泛应用的石墨电极接头外锥螺纹测量工具为片型极限量规,使用片型极限量规测量石墨电极接头外锥螺纹的具体方法如下:(1)当测量石墨电极接头外锥螺纹锥度参数时,选用两片锥度分别为最大控制锥度和最小控制锥度的片型极限量规,通过对比两片量规在被测石墨电极接头上的摆动状况判断被测石墨电极接头的锥度是否在控制范围之内。(2)当测量石墨电极接头外锥螺纹最大中径参数时,选用两片分别为最大控制直径和最小控制直径的片型极限量规,通过对比两片量规在被测石墨电极接头上的通过状况判断被测石墨电极接头的最大中径参数是否在控制范围之内。但是上述片型极限量规存在以下不足之处:(1)、只能确定被测石墨电极接头的外锥螺纹参数 ...
