Description
Technical field
The present invention relates to rolling ring outside diameter measuring technical field, be specifically related to a kind of rolling ring external diameter on-line measurement mechanical device and measuring method.
Background technology
At present, general small-sized ring list radial rolling equipment does not have ring external diameter on-line measurement device, after ring external diameter reaches precalculated position, just stop the rolling of ring.The radial-axial rolling process of large ring can be carried out according to predetermined loading curve, but the ring piece rolling technique process of advanced person should detect in real time, and wherein the most difficult is the accurate detection of ring external diameter.The detection of ring external diameter can adopt laser range finder, but for hot rolling ring, the oxide skin of ring and roll cooling water etc. all can bring very large interference to laser ranging, therefore, laser range finder for a lot of rolling ring external diameter on-line checkingi and inapplicable.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of rolling ring external diameter on-line measurement mechanical device and measuring method, achieving the on-line checkingi of rolling ring external diameter under various operating mode.
In order to achieve the above object, the technical scheme that the present invention takes is:
A kind of rolling ring external diameter on-line measurement mechanical device, dynamic beam 2 before comprising, front dynamic beam 2 connects into a movable frame by guide post 3 and rear dynamic beam 8, front dynamic beam 2 is provided with and measures roller 1, measure roller 1 to rotate along with ring, guide post 3 and front built-in beam 4, the fairlead 12 that rear built-in beam 7 is installed coordinates, guide post 3 can come and go slip in fairlead 12, front built-in beam 4 connects into a fixed frame by connecting plate 5 and rear built-in beam 7, front built-in beam 4 is provided with limited block 13, limited block 13 is used as mechanical position limitation when front dynamic beam 2 retreats, oil gas one cylinder 6 is installed in rear built-in beam 7 front end, oil cylinder piston head and cylinder piston head can both stretch out from rear built-in beam 7, the displacement transducer 14 detecting piston rod position is installed in cylinder, cylinder piston head is by cylinder connector 9, cylinder flange 10 and rear dynamic beam 8 are bound up, oil cylinder piston head is provided with cylinder connector 11, when cylinder loculus enters compressed air, cylinder piston rod is retracted, drive movable frame forward, measurement roller 1 is pressed on ring external diameter.
The measuring method of described on-line measurement mechanical device is: in ring rolling process, cylinder loculus enters compressed air, cylinder piston rod is retracted, drive movable frame forward, measuring roller 1 is pressed on ring external diameter, by the displacement transducer 14 installed in cylinder obtain the external diameter that cylinder piston rod position can converse ring, thus realize the real-time detection of ring external diameter, because the active force of cylinder loculus is less, the pressure measuring roller 1 pair of ring can not have an impact to ring parts rolling forming, simultaneously due to the compressibility of gas, when ring external diameter increases suddenly, measure roller 1 to drop back instantaneously, be unlikely to damage measurement mechanism, when ring external diameter reduces suddenly, measure roller 1 to advance instantaneously, still lean against on ring external diameter, when movable frame Long Distances moves forward, the speed of air cylinder driven movable frame is very fast, and cylinder piston rod retraction speed is slower, the quick advance of oil cylinder restraint framework, thus reduce the impact of movable frame motion.
The invention has the beneficial effects as follows: the on-line checkingi being achieved rolling ring external diameter under various operating mode by a set of mechanical device.
Accompanying drawing explanation
