Embodiment
In order to make those skilled in the art understand better technical scheme of the present invention, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1, a kind of ring thread gage for detection of graphite electrode nipple 1, comprises benchmark ring thread gage 3 and the small end ring thread gage 2 with identical tapering and outside diameter.The tapering of two ring gauges is identical with the externally threaded tapering of graphite electrode nipple circular cone of standard.Two ring gauges can be screwed on the circular cone external thread of graphite electrode nipple 1 homonymy to be measured successively.That is to say, the interior ring diameter of benchmark ring thread gage 3 is greater than the interior ring diameter of small end ring thread gage 2.Wherein, benchmark ring thread gage 3 is screwed in the position near graphite electrode nipple 1 center end face, and small end ring thread gage 2 is screwed in the position near graphite electrode nipple end.Between benchmark ring thread gage 3 and graphite electrode nipple 1 center end face, leave spacing, this spacing can be decided to be 10mm.
As shown in Figures 2 and 3, in benchmark ring thread gage 3, be equipped with conical internal thread, excircle cuff has datum line scale strip 6.The conical internal thread thickness of benchmark ring thread gage 3 is 3～5 externally threaded ridge numbers of graphite electrode nipple 1 circular cone to be measured.
As shown in Figure 4 and Figure 5, in small end ring thread gage 2, be equipped with conical internal thread, excircle cuff has taper value scale strip 5.Scale on taper value scale strip 5 is symmetrical distribution centered by the externally threaded standard taper of graphite electrode nipple circular cone.The conical internal thread thickness of small end ring thread gage 2 is 3～5 externally threaded ridge numbers of graphite electrode nipple 1 circular cone to be measured.
While detecting the tapering of graphite electrode nipple 1 to be measured, benchmark ring thread gage 3 and small end ring thread gage 2 are screwed on graphite electrode nipple 1 successively.After screwing, the datum line that survey crew only need be observed on benchmark ring thread gage 3 points to the measurement taper value on taper value scale strip 5, just can determine whether the externally threaded tapering of circular cone of graphite electrode nipple 1 to be measured meets standard.
The utility model is in order to increase measurement function, thus set up the parts that can measure graphite electrode nipple 1 central diameter value to be measured, specific as follows:
