Technical field
The utility model is a kind of to adopt the gauging instrument of mechanical measuring means as feature, is specifically related to a kind of surveying instrument of measuring oil pipes internal thread height.
Background technology
In the past, the detection of petroleum pipeline internal thread height was with plug thread gauge, judged that with the size of compact distance whether it is qualified.To the bastard thread detecting, its error amount cannot directly be learnt, also just cannot effectively adjust the equipment of machining screw, is unfavorable for processing.2006, China Patent No. is 2006200796074 to disclose a kind of instrument for measuring inner thread height of petroleum pipe, it is mainly made up of body, fine motion lever, survey tip part, indicating gauge and finger plate, fine motion lever is positioned at body middle part, the through hole of body left is vertically passed in the lower end of surveying tip part, be overlapped on one end of fine motion lever, the sounding rod of indicating gauge, vertically through right-hand through hole of body, is overlapped on the other end of fine motion lever; The middle part hinge of finger plate is on the gauge stand of tube wall, and the left front end of finger plate has a compression leg, and compression leg keeps in touch with the tip of surveying tip part.When measurement, first press down the right-hand member of finger plate, compression leg is lifted, select to put thereon with the corresponding proof-reading block of screw thread specification to be measured, amount instrument is surveyed to point and insert in the U-lag of proof-reading block, adjust the pointer of indicating gauge to zero-bit, then measuring instrument is surveyed to point and be placed in and in thread groove to be measured, do small arc-shaped and swing, if pointer always points to negative value while swing, maximum negative value should be the minus deviation of thread depth, if pointer only indicate on the occasion of, minimum on the occasion of the overgauge that should be thread depth.This measuring instrument can be measured the height number of petroleum pipeline internal thread intuitively, exactly, and numerical value not only can accurately judge that whether qualified the height of this screw thread is thus, and can also adjust in time process equipment according to this value.It has the advantages such as measurement is convenient, precision is accurate, reproducible.But the problem that this measuring instrument exists is: 1. in actual measurement process, by the beat moment reading out data of indicator gage finger, tester's operative skill is had relatively high expectations, easily occur data read errors, it is not convenient to operate; 2. indicating gauge movement is easily by the oil in environment and contamination by dust, and measuring accuracy reduces, and shorten serviceable life.
Summary of the invention
The purpose of this utility model is to overcome the existing above-mentioned defect of existing petroleum pipeline internal thread height-gauge, proposes a kind of oil pipes internal thread height-gauge of measuring numerical value memory function that has; The casing structure that improves indicating gauge, improves its anti-pollution ability.
The technical scheme that realizes above-mentioned purpose is: a kind of oil pipes internal thread height-gauge, comprise body, fine motion lever, survey tip part, indicating gauge and finger plate, it is characterized in that: the watch glass center of indicating gauge is provided with a circular hole, a measurement memory storage is installed on circular hole, described measurement memory storage is mainly by memory pointer seat, be fixed on memory pointer and reset button composition on memory pointer seat, memory pointer seat is positioned at watch glass the inside and is contained on watch glass by shell fragment, the front end of memory pointer is bending state, the indicator of indicating gauge and the front end of memory pointer overlap in measuring process.
In the time measuring oil pipes internal thread height, the memory pointer being overlapped on indicating gauge indicator can be driven by indicator, in the time finding the maximum deflection difference value of thread depth, memory pointer rests on this position, can accurate recording and the maximum error value that shows test product.
Further, the watchcase of described indicating gauge is monolithic construction.
The utility model has the advantage of: the measurement memory storage on indicating gauge can automatic accurate record and the maximum deflection difference value of demonstration test product thread depth, and avoiding people is error in reading, measures more accurate and quick.The integral housing of indicating gauge can prevent oil and the pollution of dust to movement better, and stability and the reliability of measuring instrument are increased dramatically, and significantly extend serviceable life.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Shown in Fig. 1-3, essential structure of the present utility model is identical with the disclosed instrument for measuring inner thread height of petroleum pipe of China Patent No. 200620079607.4, it comprises body 1, fine motion lever 2, surveys tip part 3, finger plate 4 and indicating gauge 6, fine motion lever 2 is positioned at body 1 middle part, the through hole of body 1 left is vertically passed in the lower end of surveying tip part 3, be overlapped on one end of fine motion lever 2, the sounding rod of indicating gauge 6, vertically through right-hand through hole of body 1, is overlapped on the other end of fine motion lever 2; The middle part hinge of finger plate 4 is on the gauge stand of body 1 outer wall, and the left front end of finger plate 4 has a compression leg 5, and compression leg 5 keeps in touch with the tip of surveying tip part 3.Improvement part is: the center of watch glass 7 is provided with a circular hole, a measurement memory storage 10 is installed on circular hole, measuring memory storage is mainly made up of memory pointer seat 12, memory pointer 13 and reset button 11, memory pointer 13 is fixed on memory pointer seat 12, memory pointer seat 12 is positioned at watch glass 7 the insides and is contained on watch glass 7 by shell fragment II14, shell fragment I15, the front end of memory pointer 13 is bending state, and the indicator 8 of indicating gauge 6 overlaps in measuring process with the termination of memory pointer 13.
