Description
Technical field
The utility model relates to UOE quality testing field, relates in particular to a kind of outer diameter of steel pipes ovality pick-up unit.
Background technology
At present, the production oil and gas pipelines requires the heavy caliber straight-line joint submerged arc welding tube product of steel pipe to carry out in the use standard both at home and abroad, and the ovality of welded tube is a crucial quality standard.Each manufacturer all needs to adopt the means of relevant detection ovality to guarantee to require and the phase closing precision in manufacture course of products and checkout procedure for this reason.Prior art discloses a kind of round steel ovality on-line measurement instrument among the Chinese patent CN87212937, two pairs of optical windows are mutually at framework and are arranged vertically in this detector, to measure the size of two positions, calculate ovality.When this pick-up unit can not accurately be felt relieved when measured piece, have bigger scale error; And, can not detecting in wholecircle week to obtain the minimum and maximum diameter of circular measured piece, its ellipticity error that calculates is bigger.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of outer diameter of steel pipes ovality pick-up unit of UOE, because of the deviation of shake and the generation of steel pipe camber, improved the accuracy that ovality detects in the time of avoiding the steel pipe rotation when this pick-up unit detects.
The utility model is achieved in that a kind of outer diameter of steel pipes ovality pick-up unit of UOE, comprise the rotation driven roller, base, slide rail, slide block, gage beam and electric pushrod, the total pair of parallel of described rotation driven roller is arranged side by side, base is arranged on the rotation driven roller radially, a pair of slide rail is symmetricly set on the two ends of base, a pair of slide rail is arranged forming V-shape, described slide block is arranged on the slide rail, described electric pushrod is arranged on the base and links to each other with slide block, be provided with compression spring between electric pushrod and the slide block, slide block is provided with displacement transducer, described gage beam is fixed on the slide block, the measurement side of a pair of gage beam is parallel to each other, and it is perpendicular with the axis of rotation driven roller to measure side.
Also be provided with the weld seam sensor on the described base.
When detecting, the outer diameter of steel pipes ovality pick-up unit of the utility model UOE can avoid steel pipe when rotation deviation because of shake and the generation of steel pipe camber, improved the accuracy that ovality detects, the quality risk that the omission of pipe flase drop causes the user thereby the ovality of better having avoided running into exceeds standard in producing steel pipe.

Embodiment 1
As shown in Figure 1, a kind of outer diameter of steel pipes ovality pick-up unit of UOE, comprise rotation driven roller 1, base 2, slide rail 3, slide block 4, gage beam 5 and electric pushrod 6, described rotation driven roller 1 total pair of parallel is arranged side by side, base 2 is arranged on rotation driven roller 1 radially, a pair of slide rail 3 is symmetricly set on the two ends of base 2, a pair of slide rail 3 is arranged forming V-shape, described slide block 4 is arranged on the slide rail 3, described electric pushrod 6 is arranged on the base 2 and links to each other with slide block 4, be provided with compression spring 10 between electric pushrod 6 and the slide block 4, slide block 4 is provided with displacement transducer 7, described gage beam 5 is fixed on the slide block 4, and the measurement side 8 of a pair of gage beam 5 is parallel to each other, and it is perpendicular with the axis of rotation driven roller 1 to measure side 8.
In the utility model, in order the maximum gauge and the minimum diameter place of welded tube to be positioned, also be provided with weld seam sensor 9 on the base 2 of this pick-up unit, when measuring diameter, detect the angle of this diametrical position and weld seam, so that identification.
When detecting, after tested steel pipe arrived and measures the position, electric pushrod 6 started, and gage beam 5 beginnings are moved until measuring the side 8 tested outer surface of steel tube that reclines at slide rail 3; Simultaneously drive tested steel pipe around the axis rotation, detected the weld seam signal by weld seam sensor 9, detect standby condition and finish until the weld seam of tested steel pipe by rotation driven roller 1.
Host computer obtains detecting standby condition and finishes to send behind the signal and refer to that letter begins detection, rotation driven roller 1 continues to drive tested steel pipe and rotates around axis, remain in the rotary course and measure the side 8 tested outer surface of steel tube that recline that float, simultaneously with the external diameter data of displacement transducer 7 and rotational angle signal real-time Transmission to host computer.
After the tested steel pipe of host computer calculating rotation reaches 180 degree, send the detection end signal, simultaneously data are handled, draw detected welded tube ovality value.
