The invention achieves the advantages of reasonable structure, high detection speed, high sensitivity, simple operation and high work efficiency.
Description
Technical field:
Present technique belongs to detection range, is specifically related to the big shaft concentricity of power station power-equipment hydraulic generator unit, accurate a kind of piano wire--the photoelectricity differential instrument that detects of great parts such as the rotor pole face depth of parallelism.
Background technology:
In present hydraulic turbine equipment manufacture,, when detecting the depth of parallelism of macro-axis right alignment, rotor pole face, adopt piano wire-earphone to survey method because detected object is big, checkout equipment is limited more.But this survey method usually can be because testing staff's hearing differs, the electric current of earphone differs, and causes the precision that detects not high, and precision is the highest also more than 0.02mm, and the sensitivity of this method is not high in addition, influences the efficient of testing.
Summary of the invention:
The object of the invention is to provide the technical scheme of a kind of piano wire-photoelectricity differential instrument, solve the measuring accuracy and the not high shortcoming of sensitivity that exist in the prior art, and operation is simple, high efficiency.
To achieve these goals, the present invention adopts technical scheme as described below.
Described " piano wire-photoelectricity differential instrument " its mainly by by measuring seat, microdrum, connected body is sought limit device four parts and is constituted, microdrum one end is fixed on the measuring seat, its other end by connected body with seek the limit device.
Above-mentioned measuring seat is a square, adopts 45# quenching material.The bottom surface is provided with " V " type groove, and the bottom surface separated into two parts, these two parts contact with detected, and a round boss is arranged above, has blind hole in the middle of this boss, and with the microdrum clearance fit, the blind hole sidewall has two screws, and screw is equipped with bolt, and this bolt locking is used.
Above-mentioned microdrum, it is made up of stationary magazine creel and rotating cylinder, and the little axle of stationary magazine creel is connected with measuring seat by clearance fit, and rotating cylinder one end is enclosed within on the stationary magazine creel.Side at measuring seat has screw, and screw is mixed clamping screw, tightens and can lock microdrum.
The rotating cylinder other end of microdrum with seek the limit device and be connected, this connection is the interference fit connected mode in axle-hole.The precision of this microdrum is 0.01mm, and range is 25mm, clockwise rotates rotating cylinder (among the figure shown in 1) and for increasing, is rotated counterclockwise to subtracting. the moving lattice reading of revolution changes 0.01mm.The metering system of microdrum: according to the helical motion principle, when microdrum (claiming the movable mark tube again) when rotating a circle, micrometric screw advances or a slow astern pitch---and 0.5 millimeter.Like this, behind calibration of microdrum rotation, it turned over for 1/50 week, and at this moment screw rod has moved 1/50 * 0.5 millimeter=0.01 millimeter along axis, therefore, used milscale can accurately read 0.01 millimeter numerical value.
Above-mentioned connected body comprises spring, connection seat, during assembling the connected body spring terminal with seek limit device thread connection, spring fastens the power supply of seeking the limit device.The other end and microdrum interference fit joint.
The above-mentioned limit device of seeking is made of cylindrical shell, power supply, pilot lamp, induction sphere, retracing spring, when induction sphere touches piano wire, form the loop, pilot lamp is bright, when induction sphere is run into surface of the work and off-center when too many, only need return, retracing spring can retract the salty ball automatic capturing center of answering.
To measure the rotor pole face depth of parallelism is the example explanation:
1: earlier with rotor level-off on lathe, find appropriate position, hang up piano wire.
2: utilize photoelectricity differential instrument baseplane to be close to rotor magnetic pole and mount face top, mobile repeatedly differential instrument, and regulate microdrum length, and just in time touch piano wire up to induction sphere, make differential instrument and piano wire produce current return, make pilot lamp glittering.At this moment reading numerical values from the microdrum, and record.
3: photoelectricity differential instrument moves on to the rotor magnetic pole basifacial, the inspection method of repeating step 2.Reading numerical values from the microdrum, and record again.
4: follow the numerical value of measuring according to upper and lower two times, calculate the survey measurements difference twice by plus-minus, how many depth of parallelisms that just can draw rotor pole face is.
The present invention is rational in infrastructure, the energy fast detecting, and highly sensitive, operation is simple, high efficiency.
