Description
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 pitch.
Background technology
In the past, the detection of petroleum pipeline internal thread pitch was with plug thread gauge, judged that with the size of compact distance whether it is qualified.To the defective screw thread detecting, its error amount cannot directly be learnt, also just cannot effectively adjust the equipment of machining screw, is therefore unfavorable for processing.2006, China Patent No. 200620079611.0 discloses a kind of instrument for measuring inner thread pitch of petroleum pipe, it is mainly made up of force transferring part, fork parts, indicating gauge, slide parts, the sounding rod termination of indicating gauge contacts with the right-hand member head of force transferring part, the measuring head of fork component upper ends contacts with the left end head of force transferring part, and the right measuring head on slide is that left measuring head is corresponding with the measuring head of fork parts lower end.Before measurement, adjust and fix right measuring head, making itself and left measuring head spacing equal flight pitch to be measured, then with pitch template check and correction amount instrument, indicating gauge is adjusted to zero-bit.When measurement, left measuring head and the right measuring head that is fixed on slide are placed in respective threaded groove, and taking right measuring head as axle center at arbitrary side oscillation one small arc-shaped, the positive reading of its minimum or maximum negative reading are exactly pitch error.This petroleum pipeline internal thread pitchometer can be measured petroleum pipeline internal thread screw-pitch deviation numerical value intuitively, exactly, judge that whether this internal thread pitch is qualified, the equipment that also can adjust timely and effectively according to overproof numerical value machining screw, has improved work efficiency greatly.But the problem that above-mentioned measuring instrument exists is: 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.
Summary of the invention
The purpose of this utility model is to overcome existing petroleum pipeline internal thread pitchometer and easily occurs data read errors and operate not defect easily, proposes a kind of oil pipes internal thread pitchometer of measuring numerical value memory function that has.
The technical scheme that realizes above-mentioned purpose is: a kind of oil pipes internal thread pitchometer, comprise force transferring part, fork parts, indicating gauge, slide parts, the sounding rod termination of indicating gauge contacts with the right-hand member head of force transferring part, the measuring head of fork component upper ends contacts with the left end head of force transferring part, right measuring head on slide is corresponding with the left measuring head of fork parts lower end, 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 pitch, the memory pointer being overlapped on indicating gauge indicator can be driven by indicator, and in the time finding the maximum deflection difference value of pitch, memory pointer rests on this position, can accurate recording and the maximum error value that shows test product.The utility model has the advantage of: measurement memory storage can record and show the maximum deflection difference value of test product pitch exactly, and avoiding people is error in reading, measures more accurate and quick.

Fig. 3 indicates souvenir to recall device schematic diagram in Fig. 1.
In figure: 1. indicating gauge, 2. watch glass, 3. indicator, 4. slide, 5. right measuring head, 6. fork, 7. goes up measuring head, and 8. left measuring head is 9. measured memory storage, 901. reset button, 902. memory pointer seats, 903. memory pointers, 904. shell fragment II, 905. shell fragment I, 906. adjust screw.
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 pitch of petroleum pipe of China Patent No. 200620079611.0, it comprises force transferring part, fork 6, indicating gauge 1, slide 4, the sounding rod termination of indicating gauge 1 contacts with the right-hand member head of force transferring part, the upper measuring head 7 of fork 6 upper ends contacts with the left end head of force transferring part, right measuring head 5 on slide 4 is corresponding with the left measuring head 8 of fork 6 lower ends, improvement part is: the center of watch glass 2 is provided with a circular hole, a measurement memory storage 9 is installed on circular hole, measure memory storage 9 mainly by memory pointer seat 902, memory pointer 903 and reset button 901 form, memory pointer 903 is fixed on memory pointer seat 902, memory pointer seat 902 is positioned at watch glass 2 the insides and passes through shell fragment II 904, shell fragment I 905 is contained on watch glass 2, the front end of memory pointer 903 is bending state, the indicator 3 of indicating gauge 1 overlaps in measuring process with the termination of memory pointer 903.
As shown in Figure 3, memory pointer 903 riveteds are on memory pointer seat 902, reset button 901 small ends have been attacked internal thread, the circular hole of the small end of reset button 901 from watch glass 2 passes, the handle of reset button 901 is positioned at the outer end of watch glass 2, shell fragment II 904, memory pointer seat 902, shell fragment I 905 is sleeved on the bar of reset button from the small end of reset button 901 successively, adjusting screw 906 is connected with the internal thread of reset button 901 small ends, making to recall hand rest 902 is sleeved on reset button 901 from the inside of watch glass 2, and keep in touch state by shell fragment II 904 and shell fragment I 905 with the inside surface of watch glass 2.Adjust screw 906 by rotation, can make the elasticity between memory pointer seat 902 and watch glass 2 be regulated.The handle that rotates reset button 901 can drive memory pointer seat 902 to rotate.
Before measurement, adjust and fix right measuring head 5, making left measuring head 8 spacing of itself and fork 6 lower ends equal flight pitch to be measured, then with pitch template check and correction amount instrument, indicating gauge 1 is adjusted to zero-bit.When measurement, left measuring head 8 and the right measuring head 5 that is fixed on slide 4 are placed in respective threaded groove, and taking right measuring head 5 as axle center at arbitrary side oscillation one small arc-shaped, the negative reading of the positive reading of its minimum or maximum is exactly pitch error.In the time that indicator 3 rotates, stirred by indicator 3 with the memory pointer 903 of its overlap joint, in the time finding maximum deviation numerical value, memory pointer 903 is parked in maximum deflection difference value place, so just records and shown exactly the maximum error value of test product.
The utility model can, by changing the bulb diameter dimension of left measuring head 8 and right measuring head 5, be measured the oil pipes internal thread pitch of different size.
The utility model indicating gauge also can replace with the digit display dial gauge with memory function, joins by data-interface and data processor, can realize on-line automatic measurement and data and automatically process.
