Of precision of position of rotor of numerical control machine tool detect automatically

01, device of fiducial circumgyrate graduation repeats precision for 0.

2. Precision of position of rotor of keyword laser interferometer is automatic 5 document label piles up ＋ of TP274 of date of classification of the graph in measuring B one, instrument composition instrument refracts bracket of lens, illuminator, RX10 by ML10 laser head, angle fiducial circumgyrate graduation is angry (next graphs) , . 2, the beam of light that measures principle laser hair to go out, through angle refractive lens dissension becomes two bundles of parallel beam of light, refract angle illuminator to reflex an angle to refract lens to incorporate again a bundle of light, be received by laser head exploration aperture next. When the rotor that be measured produces roll, mobile sex arises to interfere stripe in returning beam of light, these stripe are received by laser head exploration aperture, undertake detecting through in-house smooth detector. Be inserted inside and the stripe amount that computation circuit records mobile generation. Measure software to undertake correction to this through turning over sine to calculate, the reading of linear stripe tally, changeover becomes angle reading, calculate again next angle error shows in column of computer screen error. 3, measurement technique 1.

Graduator of RC10 fiducial circumgyrate is commonly used term A face: By that one side of graduator motor drive, also be the scale that installs angle illuminator. B face: Secure that one side on graduator housing permanently, also be the scale that installs rotor be metricaled. Standard position: The red dot on the red dot that goes up when graduator cylinder and A face is aimed and when graduator is in a lock to decide position, namely graduator is in standard position. The lock decides with remove when condition: When graduation does not have clearance between gas cylinder and A face, graduator is locked up to decide, namely software collects data condition; From the lock when graduator calm condition switch arrives remove when the lock decides position, a face and graduator main body are broken away from, a scale moves up about 2.

5mm, as the roll of rotor be metricaled, a face manages through the sea of graduator (Hirth) axis, arrive to be measured for a retrorse circumgyrate with every 5 ° the standard position with rotor rotational place. Explore Kong Li aspect in order to ensure laser light beam can be returned to laser head. 2.

Measure the fiducial circumgyrate graduator that uses RXIO rotor precision to measure software and photograph form a complete set, install angle illuminator in roof of fiducial circumgyrate graduator (A face) on, get on installation of fiducial circumgyrate graduator in rotor be metricaled again, installation of angle reflection lens is compared in the machine tool appropriate locally (stand by fiducial circumgyrate graduator as far as possible) , debug the smooth road collimation between laser interferometer and angle reflection lens and angle illuminator next, ensure fiducial circumgyrate graduator, decide in the lock with remove the lock decides condition to fall and between position of two terminal target when switch, signal of smooth road intensity is measuring range in. When beginning to measure, measure standard position certainly above all, when rotor be metricaled roll arrives when certain target position, fiducial circumgyrate graduator decides condition switch to arrive from the lock remove the lock decides position, secure the roof on fiducial rotor graduator (A face) break away from with main body of fiducial circumgyrate graduator, roof (A face) pull an angle illuminator to move up about 2.

5mm, it is a circumgyrate with every 5 ° to opposite way next what what turn to rotor be metricaled is fiducial locally. According to measure rotational order to repeat 5 times collect data automatically, measure software according to RXIO rotor precision next, have statistical analysis and scale figure to angle error, judge the positional precision that decides the axis that be measured finally. 4, measure measure 1. Join laser interferometer and fiducial circumgyrate graduator come the computer, receive electrify source. 2. Install laser interferometer, angle refracts lens, angle illuminator, fiducial circumgyrate graduator, debug smooth road collimation. 3. Measure software according to RX10 rotor precision, a target position and end end position are set on computer entree sheet, mix for 0 ° normally 360 ° , the angle between each target position (the angle that moves to need roll to rotor of next target position from position of a target namely, namely circumgyrate span) , if conceivable enough much collection measures data, criterion somes circumgyrate span setting is small, normally every other 15 ° or 30 ° establish position of a target. 4. Precision of rotor of the RX10 that start measures software, new calibration measures an order, make sure roll of fiducial circumgyrate graduator freelies. Fixed position must have to fiducial circumgyrate graduator before measuring, the red place on the red dot that gets on cylinder of fiducial circumgyrate graduator namely and A face is right neat, and fiducial circumgyrate graduator is in a lock to decide position, when be being measured namely at 0 o'clock the position. 5. Use two-way and alternant rotational order to undertake metrical, measure each target place from roll of a direction first namely (0 ° ～ 360 ° ) , measure from contrary directional roll again (0 ° of 360 ° ～ ) . Measure rotational order according to this, till finish the measurement of a requirement,turn frequency. Additional, when the editor measures rotational order, even mature of a target position and end end position jump over Cheng, choose 5 ° normally, main consideration eliminates the gap when changing direction. 6. The system controls the roll of the rotor that be measured, the editor measures rotational order one paragraph, this program and the data that computer entree sheet sets collect program photograph to agree. Next, according to measure rotational order ordinal roll arrives on buy of every eye scalar potential, keep a paragraph on buy of every eye scalar potential enough long time. So that RX10 rotor precision measures software, monitoring is measured the every target position of rotor, await stability to be in " reading stability " in limit, immediately RX10 rotor measures software with every second 5 measurement speed undertakes collection data. Retention period accident by " measure period " parameter decision. Collect the time of data, show by the arrowhead that increases ceaselessly on computer screen will make clear. End when arrowhead " measure period " when, RX10 rotor measures software to will collect data to undertake average, the angle error that computation gives this target seat shows column of error of Yu Bing act is medium, also show figure of angle error trend at the same time. As the addition that measures a number, be shown graph of angle error trend also is changed subsequently, accordingly, be mirrorred intuitionisticly comparably and observe the error that measures point of view every time is worth. According to after measuring rotational order to repeat two-way and alternant data 5 times to collect, have collection data saving file to disk. 7. The data that start analyses software, can according to GB10931 - 89 or the standard such as the general IS0230 on international, VDI/DGQ3441, come assess is measured the positional precision of rotor of numerical control machine tool. Include fixed position precision, repeat fixed position precision, retrorse deviation and positional error. The deviation trend that and can print a primitive deviation data that measures place of each eye scalar potential every time reachs rotor position precision analyses a graph. Lend the factual error that this reflects a rotor that be measured intuitionisticly the circumstance, get the referenced data of deviation of the rotor that be measured, so that improve,assemble craft and compensation to amend.
