Embodiment Construction

[0023] Such as Figure 1-Figure 5 As shown, the present invention comprises: operating panel 3, the connection mode that adopts several fixing bolts 4 (the present embodiment is two) is relatively installed on the bottom plate 5 below the operating panel 3, wherein, the middle position of the operating panel 3 is installed with a The basic knob 1 is provided with an accurate positioning ring 2 on the basic knob 1.

[0024] The shape of the above-mentioned operating panel 3 is a double T shape.

[0025] Such as Figure 6-1 to Figure 6-4 Shown, the present invention adopts following measurement steps:

[0026] The first step: unscrew fixing bolt 4, the present invention is installed on the screw nut seat crossbeam 9 of tensile test piece gauge 6 (its spacing is 10mm), then, tighten fixing bolt 4;

[0027] Step 2: Make the first column of basic gauge length 12, that is, the basic gauge length: put the tensile test piece 10 in the seat groove of the tensile test piece gauge 6, ...

Abstract

A method for measuring a precise locator of a tensile test piece gauge. The precise locator of a tensile test piece gauge includes: an operating panel and a base plate installed under the operating panel, wherein a foundation is installed in the middle of the operating panel Knob, the base knob is fitted with a precise positioning ring. The invention not only expands the range of measurement accuracy of the tensile test piece gauge, solves the problem that the tensile test piece gauge cannot adjust the gauge distance, but also greatly improves the precision of the tensile test piece gauge , so that the gauge distance of the tensile test piece gauge gauge is accurate to 0.5mm from the original 10mm, which meets most of the standard requirements.

Description

technical field [0001] The invention relates to a locator, in particular to a measuring method for an accurate locator used for a gauge of a tensile test piece in a metal material tensile test. Background technique [0002] At present, tensile test is an important indicator for evaluating the properties of metal materials. Among them, a very important item in the tensile test is to mark the original gauge length of the tensile test piece. However, there are various ways to mark the original gauge length, and different standards have different requirements for measurement methods and measurement accuracy. The commonly used instrument for marking the original gauge length of the tensile test piece is the tensile test piece gauge. However, when the tensile test piece gauge is used to measure, because its accuracy is 10mm, it cannot meet the requirements of some standard specifications; and because the designed gauge distance is relatively Fixed (generally 10mm), therefore, w...
