Description
Technical field
The invention belongs to measurement of planeness fields, a kind of compensation method when being specifically the measurement of planeness.
Background technique
Traditional measurement of planeness mostly uses following measurement method:
Measuring head on measuring device takes n point (n >=2) on product to be measured, obtains in measuring head to product to be measured n point
Distance, distance value Y1, Y2 ... ... Yn；The flatness of product to be measured is acquired with least square method to acquisition Y value.
Using this measurement method to the planarity requirements of the cross slid platform of X-axis and Y-axis composition in test equipment itself
Very high, the cost of measuring device entire in this way can be very high, cross slid platform such as bad according to flatness itself, then obtain to
The value of flatness and the true value of product itself flatness for surveying product have a long way to go.
Summary of the invention
In order to solve traditional measurement mode it is excessively high to cross slid platform planarity requirements and reduce cross slid platform flatness itself
Influence to measurement result, the present invention provides the following technical solutions:
It is a kind of for the measurement of planeness when altimetric compensation method, in plane survey to itself flat of measuring device
The compensation of face degree, the measuring device include X-axis 2, and Y-axis 3, measuring head 4, the X-axis 2 and Y-axis 3 form cross slid platform 6, measurement
First 4 are fixed on cross slid platform 6, further include marble platform 1, specific measurement method are as follows: marble platform 1 is placed in by a.
Immediately below measuring head 4, cross slid platform 6 takes n point (n >=2) with measuring head 4 in marble platform 1, acquisition measuring head 4 to
The distance of n point in marble platform 1, distance value X1, X2 ... ... Xn；B. marble platform 1 is taken away, by product 5 to be measured
Underface, cross slid platform 6 take n point n >=2 on product 5 to be measured with measuring head 4, obtain n in measuring head 4 to product 5 to be measured
The distance of a point, distance value Y1, Y2 ... ... Yn；C. the value measured twice is carried out asking poor, obtains difference X1-Y1, X2-
Y2 ... ... Xn-Yn；D. the flatness of product 5 to be measured is acquired with least square method to acquisition difference.
N point is identical in n point and measuring head 4 to product 5 to be measured in the measuring head 4 to marble platform 1
Point.
By above scheme, the invention has the benefit that
1, after being compensated using this method, the flatness result that measures is closer to true value；
2, not high to the planarity requirements of X-axis and Y-axis itself using this compensation method, reduce the cost of entire measuring system.
3, this method facilitates debugging, the flatness of the corrected X that compares axis and Y-axis, can quickly reach more preferably
Effect.
Detailed description of the invention
Fig. 1 is that the present invention matches marble platform structural schematic diagram；
Fig. 2 is the structural schematic diagram that the present invention matches product to be measured；
Marble platform 1, X-axis 2, Y-axis 3, measuring head 4, product 5 to be measured, cross slid platform 6.
Specific embodiment
In order to better understand the present invention, it will be made below description more fully.
It is a kind of for the measurement of planeness when altimetric compensation method, in plane survey to measuring device itself
The compensation of flatness, the measuring device include marble platform 1, and X-axis 2, Y-axis 3, measuring head 4, the X-axis 2 and Y-axis 3 form
Cross slid platform 6, measuring head 4 are fixed on cross slid platform 6.
Specific measurement method are as follows: marble platform 1 is placed in immediately below measuring head 4 by a., and cross slid platform 6 is with measuring head
4 take n point (n >=2) in marble platform 1, obtain the distance of n point in measuring head 4 to marble platform 1, distance value
For X1, X2 ... ... Xn；B. marble platform 1 is taken away, immediately below product 5 to be measured, cross slid platform 6 is with measuring head 4 to be measured
N point is taken on product 5, these put (n >=2) identical with the point in step a, n point in acquisition measuring head 4 to product 5 to be measured
Distance, distance value Y1, Y2 ... ... Yn；C. the value measured twice is carried out asking poor, obtains difference X1-Y1, X2-Y2 ... ...
Xn-Yn；D. the flatness of product 5 to be measured is acquired with least square method to acquisition difference.
Traditional measurement method are as follows: a. is by immediately below product 5 to be measured, and cross slid platform 6 is with measuring head 4 in product 5 to be measured
On take n point (n >=2), obtain the distance of n point in measuring head 4 to product 5 to be measured, distance value Y1, Y2 ... ... Yn；b.
The flatness of product 5 to be measured is acquired to acquisition Y value least square method.
Similarly, we are according to the distance of n point in measuring head 4 to marble platform 1, both distance value X1, X2 ... ... Xn,
Obtain the Planeness value m of cross slid platform 6 itself.
Meanwhile the Planeness value that method of the invention measures is m1, the flatness for using conventional method to measure is m2, with this
Method obtains Planeness value m1 closer to the Planeness value of product 5 to be measured itself, and the Planeness value measured using conventional method
For m2 between (m1+m) and the absolute value of (m1-m), obtaining Planeness value using traditional measurement method will receive cross slid platform 6
Influence, can it is bigger than normal or less than normal, after applying the present invention, just accurate Planeness value can be measured.
