Abstract
The invention discloses a lossless detecting method of axle element, which is characterized by the following: detecting the working state end-face and radial tripping quantity through laser dynamic tracking method; fixing the reflecting light target on the operational axle element through carpenter; gaining the tripping value and direction of axle element through reflecting light target mobile data of laser dynamic tracker; gathering the dynamic three-dimensional data in the working condition; disposing the data; gaining the tripping amplitude and frequency of axle element in the rotary algorithm condition. The invention can analyze the tripping value and direction of axle element in the moving condition.
Description
Affiliated technical field
Shaft element duty end face of the present invention and radial beat eccentricity detection method relate to a kind of lossless detection method at shaft element.
Background technology
In the mechanical drive, some is very high for the jitter values of axial workpiece, and the axial workpiece excessive loss that not only can aggravate equipment such as axle, bearing, electrode or the like of beating produces huge noise, causes equipment breakdown, and can reduce the running precision of equipment, influence the quality of product.Therefore, control has strict requirement to axial workpiece to jerk value (face runout, diameter run-out) adding man-hour.Even so, but a lot of equipment is in operation process, and owing to reasons such as installation, wearing and tearing, unbalance loadings, there be suitable beating in axial workpiece, and influences the normal use of equipment.Therefore, beat (face runout, the diameter run-out) of surveying work state axial parts under high temperature is the effective means that equipment state is safeguarded.
Shaft element is in high-speed rotation in working order down, is difficult in this state the motion state of axle is described.Therefore, the axial workpiece glitch detection all is under zero load situation at present, measures with dial gauge (or clock gauge).Because measuring like this is to carry out under zero load, non rotatable situation, so consersion unit state really.Mainly be the vibration measuring method to the axial workpiece glitch detection method in the operation process at present abroad, by the vibration data of collecting device, trend analysis, signal Processing, feature contrast by to vibration frequency draw peak swing.But the method can only be carried out the measurement of diameter run-out value, can't determine the direction of beating, and can not carry out the measurement of face runout, and therefore, practical application has little significance.
Summary of the invention
The object of the present invention is to provide a kind of detection method, with real consersion unit state at shaft element duty end face and radial beat eccentricity.
The inventive method is the principle that the utilization dynamic Laser is followed the tracks of, and utilizes frock, reflected light target is fixed on the axial workpiece of running, obtains the jitter values of axial workpiece and the direction of beating by the mobile data of measuring reflected light target.
Principle of work:
1) with frock target is fixed on the surface or the end face of shaft element, makes the target can only be along perpendicular to axis direction or axially-movable;
2) the dynamic 3 D data of collection axial workpiece under equipment working state;
3) computer data is handled;
4) under evaluation work (rotation) state, the jitter values of shaft element.
Superiority of the present invention is: the jitter values and the direction analysis of beating in the time of can be to the axial workpiece motion state.

Embodiment
Embodiment 1
The strip running deviation phenomenon appears in flat cold-rolled sheet factory coiling machine when high speed wind-up, influence product quality, for finding out the reason of generation, this coiling machine is carried out diameter run-out detect under different rotating speeds.Conventional means is to use dial gauge to detect, but the high linear speed in coiling machine when rotation be dial gauge can not bear, when changeing, dial gauge can be beaten and fly near 400, so employing the inventive method, with frock target is fixed on coiling machine holder watt end, utilizes the detection of dynamic function of dynamic Laser tracker to carry out data acquisition again.According to customer requirements, when 100 rev/mins of kinds, 300 rev/mins of kinds, 400 rev/mins of kinds, 600 rev/mins of kinds, 800 rev/mins of kinds, data acquisition is carried out in the coiling machine diameter run-out, the Treatment Analysis through to data has solved this detection difficult problem.
Embodiment 2
V3 motor in rough rolling mill is found the sparking phenomenon, and the axial movement value that requires to carry out motor shaft detects, and adopts the inventive method, with frock target is fixed on the motor shaft end face, utilizes the detection of dynamic function of dynamic Laser tracker to carry out data acquisition.Data acquisition is divided into: 1,20% rotating speed; 2,40% rotating speed; 3,60% rotating speed; 4,80% rotating speed; 5,90% rotating speed; 6,50%--90%--50% rotating speed; 7,0--80%--0 rotating speed, the following function record data of application instrument utilize the coordinate function of building again of operating system to carry out data processing, draw out the play wave amplitude figure as Fig. 2 rough rolling mill, draw axial movement value.
