电焊条偏心仪是用于测量电焊条药膜涂层均匀度的在线测量仪器。多年来因无有效的检定方法,使该仪器失检和失准,为此,我们研制成了电焊条偏心仪检定器,并已通过部级鉴定。该检定器由测量台架1、双 V 型支架2、千分表4和标准棒3组成(见图)。其工作原理是基于轴心基准法。检定时,将标准棒置于等高的双 V 型支架上,以标准棒内部钢芯为主 Electrode eccentricity is used to measure the uniformity of the electrode coating film coating instrument. Over the years because there is no valid test method, so that the instrument loss of inspection and misalignment, for which we have developed a welding rod eccentricity tester, and has passed ministerial identification. The tester consists of a measuring stand 1, a double V-stand 2, a dial gauge 4 and a standard rod 3 (see figure). Its working principle is based on the axis of reference method. When the test, the standard rod placed on the same double-V-shaped bracket to the standard steel-based internal core
