Description
Technical field
The present invention relates to a kind of coordinate measuring machine measurement accuracy rapid detection methods, belong to coordinate measuring machine detection technique neck
Domain.
Background technique
The measurement accuracy detection mode of coordinate measuring machine is mainly that periodic calibration and daily gauge block detect two kinds of sides at present
Formula.
Periodic calibration is executed according to national measurement technical specification " coordinate measuring machine calibrating standard ", carries out measurement of coordinates
The detecting error of machine and the detection of the error of indication, specifically using five size gauge blocks in seven different directions in measurement space or
Position, each measurement three times, obtain 105 data, obtain the error of indication of coordinate measuring machine；Using standard ball, measure at 25 points, meter
Least square fitting ball is calculated, least square radius distance is calculated separately to 25 measurement points, the detection for obtaining coordinate measuring machine misses
Difference." calibration certificate " is provided after completing calibration, as the precision result of the coordinate measuring machine, there is validity.But this detection
Mode is costly, and specificity is strong, and it is long to account for the machine time, is suitble to check and accept or periodic verification, is not suitable in routine work to seat
The monitoring and judgement of co-ordinate measuring machine measurement accuracy.
When the detection of daily gauge block queries coordinate measuring machine measurement accuracy in calibration cycle, take it is a kind of with
Gauge block carries out the mode of simple uniaxial length detection, foundation of the testing result as the positive erroneous judgement of measurement accuracy.This detection
Gauge block used in mode need in advance 24H be put into constant temperature between measurement, and result is single, cannot reflect coordinate measuring machine comprehensively
Composite measurement error, is biased as judgment basis, is easy to cause erroneous judgement.
Summary of the invention
The purpose of the present invention: in order to realize coordinate measuring machine measurement accuracy in time, quick, accurate judgement the problem of, this hair
It is bright to propose a kind of coordinate measuring machine measurement accuracy rapid detection method simple and practical, low in cost, easy to spread.
Technical solution of the present invention:
A kind of coordinate measuring machine measurement accuracy rapid detection method, which is characterized in that by the standard component by specialized agency's calibrating
Be fixed on coordinate measuring machine workbench, by four sides of examination criteria part, calculate the length measured values of two parallel surfaces with
Error between nominal value obtains coordinate measuring machine linear measure longimetry precision；By five standard balls of examination criteria part, calculate separately
The error of the distance between the diameter of standard ball, each centre of sphere between measured value and nominal value obtains coordinate measuring machine measurement synthesis
Precision；The same point in the standard ball of top surface is detected by gyration, seat outer corner measurement precision is surveyed in evaluation；It is complete by acting above
At the quick detection of coordinate measuring machine measurement accuracy.
Specialized agency's calibrating is the length nominal value between standard verification part parallel surface, the diameter and ball of standard ball
Length nominal value between the heart.
The standard component is made of marble cube 1, the steel standard ball 2 that diameter is 25.
The marble cube 1 is having a size of 300*300*300mm3。
The standard bulb diameter is the steel of 25mm.
The standard ball is steel.
The standard ball totally 5.
Five standard ball stem portions are separately fixed on 5 faces of marble body 1 by bolt 8.
The standard component is fixed on coordinate measuring machine workbench by screw 7.
Beneficial effects of the present invention: the present invention can quickly and easily detect coordinate measuring machine measurement accuracy, comment
Sentence, and cost is relatively low, it is easy to spread.Measurement of coordinates operators can not pass through professional measurement instrument, and through the invention,
Using quick examination criteria part, before detection workpiece daily, as daily point inspection project, coordinate measuring machine measurement accuracy is carried out
Detection, it is ensured that the monitoring property of coordinate measuring machine measurement accuracy.This method efficiently solves coordinate measuring machine accuracy calibration week
Measurement accuracy test problems in phase.The present invention is not only convenient for measurement of coordinates operators and carries out fastly before measurement work daily
The detection of the measurement accuracy of speed, and a large amount of data accumulation provide foundation for the anticipation of coordinate measuring machine accuracy variation tendency.
