Description
Technical Field
The utility model relates to a be suitable for reading microscope of eddy current flaw detection appearance pipe and reform transform structure belongs to measuring instrument and reforms transform technical field.
Background
In the prior art, an eddy current flaw detection sample tube is a comparison sample for calibrating eddy current flaw detection equipment, and is required to be the same as the nominal size of a steel tube to be detected, and to be similar to chemical components, surface state and heat treatment state. When the through-coil eddy current gouging technique is used, the artificial defect on the comparative sample is a through-hole. The diameter and the spacing position of the through holes are in accordance with the specification of GB/T7735.
The measurement method of the size of the through hole is in accordance with the regulation of YB/T145. There are two methods of measuring the via size in this specification: firstly, a plug gauge pass-stop end is used for carrying out qualification judgment; the other is direct measurement using a reading microscope. Because the specification and variety of the sample tubes are more, the corresponding through holes are also more complicated in size, plug gauges with various specifications are required to be equipped, the use is frequent, the wear is easy, the traceability is poor, and the investment cost is higher. The reading microscope has the advantages of convenient use, stable indicating value, good repeatability, good traceability and low investment cost. However, when the reading microscope is used for measurement, the surface of the sample tube is a curved surface, which is not favorable for fixation and affects the measurement accuracy, so that the reading microscope cannot be widely used.
For example, chinese patent publication No. CN203310711U discloses a reading microscope measuring table. The reading microscope measuring table comprises a support, a cantilever mechanism, a cantilever support and a base, wherein the support is vertically arranged on the base; the cantilever mechanism comprises a cantilever and a cantilever fastener, the cantilever comprises strip-shaped grooves respectively arranged at two ends of the cantilever and a first through hole which can enable the support to pass through, the reading microscope is placed in the strip-shaped grooves and can move along the length direction of the strip-shaped grooves, and the cantilever fastener is used for fixedly connecting the cantilever and the support; the suspension arm support includes a slider disposed under the suspension arm, the slider having a second through hole through which the bracket can pass, and a slider fastener fixedly connecting the slider to the bracket.
The reading microscope can move back and forth after the reading microscope workbench, can ensure that the reading microscope and a sample keep relatively stable in position in the measuring process, and has the advantages of convenience in reading, accurate measuring data and the like; but the platform structure can not fix the sample tube, and the measurement accuracy is easily influenced.
Therefore, it is socially desirable to develop a reading microscope with a better fixing effect so as to improve the accuracy of the measurement result of the size of the through hole.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem of proposing among the above-mentioned background problem, provide a reading microscope who is suitable for eddy current flaw detection appearance pipe and reforms transform structure, its is rational in infrastructure, and manufacturing cost is lower, realizes eddy current flaw detection appearance pipe convenient and fast, accurate reliable measurement.
The purpose of the utility model is realized like this: a reading microscope reconstruction structure suitable for an eddy current flaw detection sample tube comprises a reading microscope body, wherein a base is arranged below the reading microscope body, the base is of a hollow structure, a light transmission area is further arranged on one side of the base, and a light source is arranged above the light transmission area;
the bottom of base is "V" type groove structure to the bottom structure that matches the base below the base is provided with V type frame.
The light source is installed above the light-transmitting area through the adjusting bracket.
The base is installed below the reading microscope body through bolts.
And a sample tube is arranged between the base and the V-shaped frame.
Compared with the prior art, the utility model has the advantages of it is following:
the utility model discloses a be suitable for reading microscope of eddy current flaw detection appearance pipe reforms transform structure, its is rational in infrastructure, and manufacturing cost is lower, can realize the fixed of appearance pipe when measuring better, realizes eddy current flaw detection appearance pipe convenient and fast, accurate reliable measurement to improve through-hole size measurement result.
