Description
Technical field
The utility model be a kind of take adopt the gauging instrument that mechanical measuring means is feature, be specifically related to a kind of surveying instrument of measuring oil pipes external thread height.
Background technology
In the past, the detection of oil pipes external thread height was with ring thread gage, with the size of compact distance, judged that whether it is qualified.To detected bastard thread, its error amount cannot directly be learnt, cannot effectively adjust the equipment of machining screw, is unfavorable for processing.2007, China Patent No. 2006200788576 discloses a kind of petroleum pipe external-thread height measuring instrument, it comprises indicating gauge, gauge stand and survey point, indicating gauge is fixed on gauge stand, the bottom section of gauge stand is arc, has a step circular hole on the vertical centre axis of gauge stand, and the measuring staff of indicating gauge and the sharp main body of survey are arranged in this step circular hole, survey sharp lower end and stretch out step circular hole, survey the measuring staff lower end butt of sharp upper end and indicating gauge.During measurement, first with tooth depth calibrated bolck, indicating gauge is adjusted to zero-bit, then survey point is placed in to tested ridge trench bottom, point is surveyed in compressing, make the curved bottom contact of gauge stand in adjacent crest of screw thread, then take and survey point as point of fixity, do small arc-shaped and swing, if pointer always points to negative value while swinging, maximum negative value should be the negative error of thread depth, if pointer only indicate on the occasion of, minimum on the occasion of the positive error that should be thread depth.This oil pipes external-thread height measuring instrument can be measured the externally threaded height number of petroleum pipeline intuitively, exactly, judges that whether the height of this screw thread is qualified, also can according to overproof numerical value, adjust in time the equipment of machining screw, has greatly improved work efficiency.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 yet.2. indicating gauge movement, easily by the oil in environment and contamination by dust, causes movement dumb, affects measuring accuracy.
Summary of the invention
The purpose of this utility model is to overcome the existing above-mentioned defect of existing petroleum pipeline external-thread height measuring instrument, 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 external-thread height measuring instrument, comprise indicating gauge, gauge stand and survey point, indicating gauge is fixed on gauge stand, the bottom section of gauge stand is arc, on the vertical centre axis of gauge stand, there is a step circular hole, the measuring staff of indicating gauge and the sharp main body of survey are arranged in this step circular hole, survey sharp lower end and stretch out step circular hole, survey the measuring staff lower end butt of sharp upper end and indicating gauge, 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, the memory pointer and the reset button that are fixed on memory pointer seat form, 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.
When measuring oil pipes external thread height, the memory pointer being overlapped on indicating gauge indicator can be driven by indicator, when 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.
As shown in the figure, essential structure of the present utility model is identical with the disclosed petroleum pipe external-thread height measuring instrument of China Patent No. 200620078857.6, it comprises indicating gauge 1, gauge stand 5 and surveys point 7, indicating gauge 1 is fixed on gauge stand 5, the bottom section of gauge stand 5 is arc, on the vertical centre axis of gauge stand 5, there is a step circular hole, the main body of the measuring staff 6 of indicating gauge 1 and survey point 7 is arranged in this step circular hole, the lower end of surveying point 7 stretches out step circular hole, survey upper end and the 7 measuring staff 6 lower end butts of point 7, (as shown in Figure 1).Improvement part is: the center of watch glass 3 is provided with a circular hole, a measurement memory storage 8 is installed on circular hole, measuring memory storage is mainly comprised of memory pointer seat 802, memory pointer 803 and reset button 801, memory pointer 803 is fixed on memory pointer seat 802, memory pointer seat 802 is positioned at watch glass 3 the insides and is contained on watch glass 3 by shell fragment II804, shell fragment I805, the front end of memory pointer 803 is bending state, and the indicator 2 of indicating gauge 1 overlaps in measuring process with the termination of memory pointer 803.
As shown in Figure 3, memory pointer 803 riveteds are on memory pointer seat 802, reset button 801 small ends have been attacked internal thread, the circular hole of the small end of reset button 801 from watch glass 3 passes, the handle of reset button 801 is positioned at the outer end of watch glass 3, shell fragment II804, memory pointer seat 802, shell fragment I805 is sleeved on the bar of reset button from the small end of reset button 801 successively, adjusting screw 806 is connected with the internal thread of reset button 801 small ends, making to recall hand rest 802 is sleeved on reset button 801 from the inside of watch glass 3, and keep in touch state by the inside surface of shell fragment II804 and shell fragment I805 and watch glass 3.By rotation, adjust screw 806, can make the elasticity between memory pointer seat 802 and watch glass 3 be regulated.The handle that rotates reset button 801 can drive 802 rotations of memory pointer seat.
