Abstract
The utility model discloses a steel tube curvature measuring tool, comprising a horizontal transverse ruler and a dial indicator. The underside of the horizontal transverse ruler is equipped with a support which possesses a prong for clamping a steel tube, and the dial indicator is assembled on the horizontal transverse ruler slidably. Aiming at the steel tube curvature measurement, the steel tube curvature measuring tool of the utility model is specially designed, has the characteristics of simple structure, convenient operation, low manufacture cost, accurate measurement, high reliability, strong practicality, etc., and provides great conveniences for finished product steel tube curvature detection.
Description
Technical field
The utility model relates to survey instrument, specifically a kind of flexibility of steel pipe survey instrument.
Background technology
Can normal use in commercial production in order to ensure steel pipe, need to detect the steel pipe of finished product, this has wherein just comprised the flexibility measurement.
At present, measurement to flexibility of steel pipe realizes by guiding ruler and Steel Ruler, no matter guiding ruler is measured, Steel Ruler is measured, and all relies on the subjective feel of workman location, and it not only measures complexity, labour intensity is large, inefficiency, and have the defective that measuring accuracy is low, error is large, can't reach the purpose of detection.
For this reason, each steel pipe's production merchant has dropped into a large amount of manpowers and financial cost, various flexibility survey instruments have been researched and developed, these achievements in research are appeared in the newspapers on public publication repeatly, for example (publication number: CN201540102U, openly day: 2010.08.04), it is by the laser body Emission Lasers for Chinese patent literature disclosed " device for detecting curvature at pipe end of steel pipe ", after the focusing by focusing, show the detected value of pipe end flexibility in laser pick-off mechanism.Undeniable, this technology is greatly easy to detect operation, and has improved the degree of accuracy of testing result.But there are the defectives such as complex structure, manufacturing cost height in it.
Summary of the invention
The purpose of this utility model is: for above-mentioned the deficiencies in the prior art, easy to operate, measure under the accurate prerequisite, a kind of flexibility of steel pipe survey instrument simple in structure, cheap for manufacturing cost is provided.
The technical solution adopted in the utility model is: a kind of flexibility of steel pipe survey instrument, comprise horizontal crossfoot and dial gauge, and the bottom surface of described horizontal crossfoot is provided with support, and this support has the prong of clamping steel pipe; Described dial gauge is slidedly assemblied on the horizontal crossfoot.
Described support is configured to by the first support of " V " type structure and second, and the first support and the second support are arranged the bottom surface of horizontal crossfoot from outside to inside successively.
Described the first support and the second rack arrangement are on the same straight line of horizontal crossfoot bottom surface.
The end face of described horizontal crossfoot is provided with chute, and dial gauge is assemblied in the chute by slide block, and the gauge head of dial gauge extends the chute bottom surface.
The end face both sides of described chute are respectively equipped with the infolding terrace, and the distance of both sides infolding terrace is less than the width of slide block.
The beneficial effects of the utility model are: above-mentioned survey instrument is specially for the measurement of flexibility of steel pipe and design, have simple in structure, easy to operate, cheap for manufacturing cost, measure accurately, the characteristics such as reliability is high, practical, for the detection of fished pipe flexibility provides very big facility.
