Abstract

The invention discloses an automatic measurement device, a system and a method for the taper thread of a graphite electrode body or a joint and belongs to the technical field of automatic measurement.The technical problem in the prior art that the existing manual measurement is large in error and low in precision can be solved. The device comprises symmetrically arranged driving assemblies and measurement tool assemblies, wherein each measurement tool assembly is provided with a standard-taper type smooth conical surface. The measurement tool assemblies are arranged between the two driving assemblies and are correspondingly connected with the driving assemblies through connecting assemblies. A distance measurement unit is further arranged between the driving assemblies and the measurementtool assemblies. A lifting unit used for driving the graphite electrode body or the joint to go up and down is arranged between the two measurement tool assemblies. According to the invention, the taper thread parameters of the graphite electrode body and the joint can be automatically measured and displayed, so that the usability is good. Meanwhile, the occurrence of manual operation errors andreading errors can be completely avoided through the automatic measurement. The precision is high, and the benefit of a manufacturer is greatly improved.

Description

technical field [0001] The invention relates to the technical field of automatic measurement, in particular to an automatic measurement device, system and method for a graphite electrode body or joint taper thread. Background technique [0002] The development of the carbon industry is becoming more and more mature, and the demand for graphite electrodes is also increasing. Due to the limitation of its own size, graphite electrodes need to be connected in series when using multiple electrodes. Two graphite electrodes are connected by graphite electrode connectors of the same specification. , at this time, the degree of engagement between the tapered thread of the graphite electrode and the tapered thread of the electrode joint is very important. When the degree of engagement of the tapered thread is low, the graphite electrode is prone to breakage accidents during use, which affects the profit of the manufacturer. Therefore, the engagement of the threaded connection part shou...
