Currently, widely applied graphite electrode nipple outer cone thread survey tool is piece type difference gauge in Tan Su enterprises, Measuring graphite electrode nipple outer cone thread using piece type difference gauge, the specific method is as follows:
(1)When measuring graphite electrode nipple outer cone thread taper parameter, it is respectively maximum control cone to select two panels taper The piece type difference gauge of degree and minimum control taper, by comparing swing situation of the two panels gauge on tested graphite electrode nipple Judge the taper for being tested graphite electrode nipple whether within control range.
(2)When measuring graphite electrode nipple outer cone thread maximum central diameter parameter, it is respectively that maximum control is straight to select two panels The piece type difference gauge of diameter and minimum control diameter passes through situation by comparing two panels gauge on tested graphite electrode nipple Judge the maximum central diameter parameter for being tested graphite electrode nipple whether within control range.
But sheet above type difference gauge has the following disadvantages:
(1), can only determine tested graphite electrode nipple outer cone thread parameter whether within control range, be unable to get Accurate data.
(2), measurement result be affected by human factors it is larger, it is more demanding to operation technique.
(3), piece type difference gauge high precision machining and yielding, use can not be repaired after deformation.
In conclusion a kind of measurement ring gauge that can accurately measure graphite electrode nipple parameters is badly in need of in Tan Su enterprises.

Specific implementation mode
Illustrate specific embodiment of the present utility model with reference to the accompanying drawings and examples, but following embodiment only uses It is described in detail the utility model, does not limit the scope of the utility model in any way..
Embodiment 1:As shown in Figure 1-Figure 3, a kind of for measuring the externally threaded special measurement ring of graphite electrode nipple circular cone Rule, include the matrix 12 being connected as one by bolt 11(Graphite material)With upper reference rings 13, lower reference rings 13A, matrix 11 is in Cyclic annular and inner peripheral surface is equipped with conical inner screw thread 14 compatible with 4 circular cone external screw thread of Standard graphite electrode contact, outer circumference surface Equipped with coaxial annular projection 15, annular projection 15 is equipped with 4-8 circumferentially uniformly distributed connection through-hole I 16;Upper reference rings 13 Inner peripheral surface it is stepped and be adapted with annular projection 15, be respectively equipped with and connect in upper reference rings 13, lower reference rings 13A I 16 corresponding II 16A of connection through-hole of through-hole, the setting of bolt 11 is in II 16A of connection through-hole I 16 and connection through-hole.
Upper reference rings 13 are additionally provided with around axis circumferentially uniformly distributed 3-6 measured hole 17, and 13 end face of upper reference rings is flat Face degree≤0.02mm.
Embodiment 2:One kind is for measuring the externally threaded special measurement ring gauge of graphite electrode nipple circular cone, as shown in figure 4, originally Implement to be with the difference place of embodiment 1:The outer circumference surface of upper reference rings 13 is equipped with central diameter value scale strip 19.
The above-mentioned operate with method for measuring the externally threaded special measurement ring gauge of graphite electrode nipple circular cone is as follows:
