Description
Technical field
The present invention relates to the device and method that the rotating shaft of a kind of non-contact measurement large deflection is beated, belong to field of industrial production.
Background technology
Along with the development of science and technology, one of problem that the production of generator and creating is paid close attention in commercial production the most.In the production of turbodynamo, rotating shaft is a critical component, and spindle outer diameter and face runout are the important indicators weighing its Vehicle Processing quality.At present, in rotating shaft Vehicle Processing process, axle journal external diameter circle beat and face runout be usually all on lathe, take mechanical type dial gauge, clock gauge measures.The metering system of this contact is subject to the impact of surveying instrument contact force, the surface of contact of workpiece and gauge head produces elastic deformation, the vibration of friction force and turning axle, wooden dipper are inclined, not only measurement instrument is easier to bad, also can cause certain measuring error, the measurement especially can beated to high rotating speed lower rotary shaft produces and hinders layer by layer.Namely rigid contact formula is measured, and surveying instrument easily damages, and has measuring error, and is not suitable for measuring at high speed.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of safe, flexible, measure the device and method that the rotating shaft of accurate non-contact measurement large deflection beats, the surveying instrument solving the measurement of rigid contact formula easily damages, there is measuring error, and be not suitable for the problem carrying out at high speed measuring.
In order to solve the problems of the technologies described above, technical scheme of the present invention there is provided the device that the rotating shaft of a kind of non-contact measurement large deflection is beated, it is characterized in that, comprise display instrument, display instrument is connected with data acquisition unit by data line, and data acquisition unit is connected with fore-lying device by two core electric wires, and fore-lying device is connected with eddy current sensor by extending cable, eddy current sensor is fixed in bracing frame, and fore-lying device is connected with power supply by two core electric wires.
Preferably, described data line is USB data line.
Preferably, described bracing frame comprises iron-absorbing base, and iron-absorbing base is fixed on lathe saddle.
A method for the device adopting the rotating shaft of non-contact measurement large deflection to beat, is characterized in that, comprise the following steps:
Step 1: each instrument data line, electric wire, cable are connected;
Step 2: power-on, check data acquisition unit and fore-lying device whether normal;
Step 3: open display instrument, check whether and can normally run;
Step 4: eddy current sensor is installed on bracing frame;
Step 5: the bracing frame with eddy current sensor is loaded on lathe saddle;
Step 6: carry out Data Collection with display instrument after starting lathe.
Preferably, the eddy current sensor described in adjusting before starting lathe, makes the probe top of eddy current sensor from tested axle journal or end face 0.5mm ~ 1.5mm.
Apparatus structure of the present invention is simple, flexible, easy to operate, goes for the rotating shaft of different size.The present invention overcomes the limitation that the contact type measurement rotating shaft of current enterprise is beated, and utilizes currents sensing technology, and the instrument wearing and tearing avoiding hard contact measurement to bring and dimensional accuracy impact, reduce measuring error, and can realize high tachometric survey; Also will go out factory-run school straightening to rotating shaft to be from now on connected between hypervelocity and to complete, save lathe in final step, and optimize pivot structure design aspect developing thinking.
