Embodiment 1

[0030] Embodiment 1: as Figure 1-Figure 2 As shown, an automatic measuring device for taper thread parameters of a graphite electrode joint, including a drive assembly 3 arranged symmetrically on both sides, a ring gauge assembly 2 with a standard taper, and a computer control system 1;

[0031] The driving assembly 3 includes a box body 31, a plurality of first hydraulic cylinders 32 and hydraulic stations 34 arranged in parallel in the box body 31, each first hydraulic cylinder 32 is connected to the hydraulic station 34 respectively, and each first hydraulic cylinder 32 is connected to the hydraulic station 34 A pressure sensor 33 for detecting the hydraulic oil pressure of each first hydraulic cylinder 32 is arranged between them.

[0032] The ring gauge assembly 2 includes a large ring gauge 21 with a standard taper and a smooth inner conical surface 6, a small ring gauge 22 and an end surface measuring device 23, and the first connection between the large ring gauge 21 ...

Embodiment 2

[0044] Example 2, such as image 3 As shown, an automatic measuring device and method for taper thread parameters of a graphite electrode joint, the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that the diameter of the conical hole on the large ring gauge 21 is greater than the maximum diameter of the small ring gauge 22 Driven by the second connecting rod 25 , the small ring gauge 22 reciprocates across the large ring gauge 21 .

[0045]The outer peripheral surface of the large ring gauge 21 and the small ring gauge 22 is a smooth outer peripheral surface 7 with a standard taper, so that this device can not only be used for automatic measurement of the parameters of the graphite electrode joint 5 taper thread, but also can be used for the taper thread of the graphite electrode body Automated measurement of parameters.

Abstract

The invention discloses an automatic measuring device and method for taper thread parameters of a graphite electrode nipple, belongs to the field of automatic measurement equipment, and aims at solving the technical problems of large error and low accuracy in existing manual measurement. The device comprises symmetric driving assemblies, and a ring gauge assembly which is provided with a standardtaper and a smooth inner tapered surface, wherein the ring gauge assembly is arranged between the two driving assemblies and is correspondingly connected to the driving assemblies through connecting assemblies; a ranging unit is further arranged between each driving assembly and the ring gauge assembly; a lifting unit for lifting the graphite electrode nipple is arranged between the two ring gaugeassemblies. With the adoption of the device and the method, taper thread parameters of the graphite electrode nipple can be measured and displayed automatically, so that the usability is high; and moreover, the measurement is automatically carried out, so that a manual operation error and a read number error can be completely avoided; and the accuracy is high.

Description

technical field [0001] The invention relates to the field of automatic measurement equipment, in particular to an automatic measurement device and method for taper thread parameters of graphite electrode joints. 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 usually require multiple electrodes to be connected in series. Two graphite electrodes are connected by graphite electrode connectors of the same specification. Connection. At this time, the degree of engagement between the graphite electrode taper thread and the graphite electrode connector taper thread is very important. When the taper thread engagement is low, the graphite electrode is prone to breakage accidents during use, which affects the manufacturer's benefits. Therefore, the screw connection part should be improved. The meshing degree is pa...
