Embodiment 1

[0030] Embodiment 1: as Figure 1-Figure 2 As shown, an automatic measurement device for taper thread parameters of a graphite electrode body, including a drive assembly 3 symmetrically arranged on both sides, a plug 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 arranged in parallel in the box body 31, each first hydraulic cylinder 32 is connected to a hydraulic station 34 respectively, and each first hydraulic cylinder 32 is connected to the hydraulic station 34. There is a pressure sensor 33 for detecting the hydraulic oil pressure of each first hydraulic cylinder 32 .

[0032] The plug gauge assembly 2 includes a large plug gauge 22 with a standard taper and a smooth outer conical surface 6, a small plug gauge 21, and an end surface measuring device 23. The rod 25 is fixedly connected, and the second digital display length meter 28 for measuring th...

Embodiment 2

[0045] Example 2, such as image 3 As shown, an automatic measuring device and method for taper thread parameters of a graphite electrode body, the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that the through hole 7 is coaxial with the large plug gauge 22, and the diameter is larger than the small plug gauge 21 so that the small plug gauge 21 reciprocates through the through hole 7 driven by the first connecting rod 24 .

[0046]The computer control system 1 receives the measurement data L3, L2, L1, L3', L2', L1' (( L1, L2, L3 are the data correspondingly displayed by each digital display length meter at the left end, L1′, L2′, L3′ are the data correspondingly displayed by each digital display length meter at the right end), and then calculated according to the trigonometric function relationship or look up the table Parameters such as the taper of the taper thread at the left and right ends of the graphite electrode body 5, a...

Abstract

The invention discloses a device and method for automatically measuring parameters of a taper thread of a graphite electrode body in the field of automatic measuring equipment, and aims to solve the technical problems of large manual measurement error and low precision. The device includes symmetrically arranged drive assemblies and plug gauge assemblies having a smooth outer conical surface of astandard taper. The plug gauge assemblies are disposed between the two drive assemblies and are connected correspondingly to the drive assemblies by connection assemblies. Distance measurement units are also arranged between the drive assemblies and the plug gauge assemblies. A lifting unit for lifting and lowering a graphite electrode body is arranged between the two plug gauge assemblies. According to the invention, the measurement and display of the parameters of the taper thread of the graphite electrode body can be automatically realized, the usability is good, and the automatic measurement can completely avoid the artificial operation error, the reading error and is high in precision.

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 a graphite electrode body. 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...
