Abstract
The utility model is provided with a petroleum pipe external-thread height measuring instrument comprising an indication meter (1) fixed on a meter stand (2), a stepped round hole on the central axis of the meter stand (2), a measuring-tip sleeve (6) connected with an adjusting block (5) using a rotary joint, and the tapered end of the measuring-tip sleeve extends out from the front end of the meter stand (2). The measuring-tip (7) is a stepped shaft with the tapered tip extending out from the tapered end of the measuring-tip sleeve (6). The other end of the measuring-tip (7) contacts with the top end of the measuring rod (9) of the indication meter. Since the measuring tip of the measuring instrument connects with a digit-indication meter, thus during measuring, the height value of the thread being measured can be directly read out from the indication meter, by which we can not only accurately judge whether the petroleum pipe external-thread is qualified or not, but also adjust the thread-making equipment effectively according to the value out-of-tolerance, which increases the working efficiency greatly and reduces the processing cost.
Description
Technical field
The utility model be a kind of be the metering outfit of feature to adopt mechanical measuring means, be specifically related to a kind of survey instrument of measuring oil pipe thread external thread height.
Background technology
At present, the detection of known oil pipe thread external thread height is with ring thread gage or plug thread gauge, judges with the size of tight distance whether it is qualified.To detected height bastard thread, its height error value can't directly be learnt, also just can't effectively adjust the equipment of machining screw, therefore is unfavorable for processing.
Utility model is held outward
The purpose of this utility model provides a kind of oil pipe thread external thread height-gauge, it can measure the externally threaded height number of petroleum pipeline intuitively, exactly, numerical value can judge accurately that not only whether qualified the height of this screw thread is thus, and can also adjust process equipment in time according to this value.
The technical scheme that realizes above-mentioned purpose is as described below:
The utility model oil pipe thread external thread height-gauge, comprise indicating gauge, indicating gauge is fixed on the gauge stand, described gauge stand external front face projection of shape is " Y " shape, a step circular hole is arranged on the central axis, the Lower shaft sleeve external diameter of the big hole of this step circular hole and indicating gauge adapts, and the small sircle hole of this step circular hole adapts with the cylindrical of surveying the point cover, each other for being slidingly matched; Surveying point cover cylindrical one end is screw thread, spins with regulating block, surveys the other end band height of point cover, stretches out the front end of gauge stand; A truncated cone-shaped through hole that adapts with the survey point is arranged on the axial line of surveying the point cover; Surveying point is the step axle, and thin round bar leading portion is the awl point, and stretches out an end of surveying point cover band height, and the round platform of surveying the sharp other end places outside the stepped hole of surveying the point cover, and its end face contacts with the measuring staff top of indicating gauge; Survey point and survey the point cover for being slidingly matched.
As a kind of improvement of the present utility model, a lining is arranged on the Lower shaft sleeve end face of indicating gauge, a wound spring that helps to survey point cover return is arranged between lining and the regulating block.
Because the survey point of the utility model oil pipe thread external thread height-gauge is connecting the numerical value indicating gauge, therefore, when measuring the externally threaded height of petroleum pipeline, just can directly read the height number of tested screw thread by indicating gauge.Can judge exactly so whether petroleum pipeline external thread height is qualified, also can adjust the equipment of machining screw timely and effectively, increase work efficiency greatly, cut down finished cost according to overproof numerical value.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is done to describe in further detail:
Fig. 1 is the whole Facad structure synoptic diagram of an embodiment of the utility model.
The side schematic view of Fig. 2 Fig. 1.
Among the figure: 1. indicating gauge, 2 gauge stands, 3. spring, 4. set nut, 5. regulating block is 6. surveyed the point cover, 7. surveys point, 8. lining, the 9. measuring staff of indicating gauge, the 10. Lower shaft sleeve of indicating gauge.
Embodiment
As shown in the figure, the utility model oil pipe thread external thread height-gauge mainly is made up of indicating gauge 1, gauge stand 2, regulating block 5, survey point cover 6, survey point 7.The bottom section of gauge stand 2 is an arc, and gauge stand 2 external front face projection of shape are roughly " Y " shape, and there is a step circular hole at the center, and Lower shaft sleeve 10 external diameters of big hole and indicating gauge 1 adapt, and small sircle hole adapts with the cylindrical of surveying point cover 6.Surveying point cover 6 cylindricals one end is screw thread, spins with regulating block 5, and there is a set nut 4 top of joint piece 5.Survey the other end band height of point cover 6, stretch out the front end of gauge stand 2; On the axial line of surveying point cover 6, have one with survey the sharp 7 truncated cone-shaped through holes that adapt; Surveying point 7 is the step axle, and thin round bar leading portion is the awl point, and stretches out an end of surveying point cover 6 band height, and the round platform of surveying sharp 7 other ends places outside the stepped hole of surveying point cover 6, and its end face contacts with measuring staff 9 tops of indicating gauge; Survey point 7 and survey point cover 6 for being slidingly matched.
To survey point cover 6 timely return in use in order making, a lining 8 to be arranged on the Lower shaft sleeve end face of indicating gauge 1, have one to help to survey the sharp wound spring 3 that overlaps 6 returns between lining 8 and the regulating block 5, as shown in Figure 1.
To survey point 7 during the assembling of this measuring instrument earlier packs into and surveys point and overlap in 6, it can be slided flexibly, regulating block 5 is spun on the threaded portion of surveying point cover 6 again, screw set nut 4, then this grip assembly is put into gauge stand 2, precession or back-out regulating block 5 can make survey point cover 6 length of stretching out gauge stand 2 reach suitable again, screw set nut 4 after regulating.Spring 3 is put on the regulating block 5, lining 8 is put on spring 3 tops, at last indicating gauge 1 is put into gauge stand 2, the Lower shaft sleeve of indicating gauge 1 passes the macropore of gauge stand 2, the measuring staff of indicating gauge 1 passes the hole at lining 8 centers, the measuring head of indicating gauge 1 contacts with the top of surveying point 7, and this moment is with indicating gauge 1 and gauge stand 2 fixing getting final product.
To survey point 7 during measurement earlier places in the tooth depth calibrated bolck U-lag, indicating gauge 1 is transferred to zero-bit, to survey point 7 then places in the V-type groove of tooth depth calibrated bolck again, the numerical value of its indication should be identical with U-lag, if must not change, indication numerical value difference, its numerical value surpass 0.013mm, if greater than this numerical value, the expression gauge head weares and teares or damages, and should change gauge head.Next carrying out the pipe thread tooth depth measures, at first should will survey point 7 according to survey pipe thread specification inserts in the U-lag, and will survey sharp 7 again to zero-bit and place tested ridge trench bottom indicating gauge 1 is whole, point 7 is surveyed in compressing contacts on adjacent crest of screw thread the curved bottom of gauge stand 2, and the instrument vertical is in the pipe thread element of cone.Be point of fixity to survey point 7 then, do little arc swing at the instrument vertical in the both sides, position of pipe thread element of cone, pointer always points to negative value during as if swing, and then Zui Da negative value should be the negative error of thread depth, if pointer only indicate on the occasion of, then minimum on the occasion of the positive error that should be thread depth.
The utility model can be measured the external thread height of the oil pipe thread of different size.
