S3: firstly, corresponding dial caliper guge measurement range lower limit is calibrated, specifically: model is measured with dial caliper guge
The zero-bit for enclosing lower limit value adjustment dial caliper guge dial gauge, according to combined gauges size, with two measuring jaw measuring surface of lever-type micrometer
It is contacted with combined gauges and finds turning point, adjusted lever-type micrometer zero-bit, then operate dial caliper guge, survey its two measuring jaw
Amount face and lever-type micrometer measure face contact, search out dial caliper guge indicating value turning point, read and show on dial caliper guge
Value, the difference of the indicating value and corresponding amount block size as correspond to the dial caliper guge error of indication of measurement range lower limit;
Then, remaining corresponding calibration point, as procedure described above repetitive operation record each more corresponding band respectively
The table caliper gauge error of indication;
S4: maximum value is the dial caliper guge error of indication in each calibration point error of indication.
Wherein, the calibration point chooses five.
Wherein, when the measurement range of the dial caliper guge is 5mm, five selected calibration points are as follows: A, A+1.25, A
+ 2.5, A+3.75, A+5, wherein A is measuring range lower limit.
Wherein, when the measurement range of the dial caliper guge is 10mm, five selected calibration points are as follows: A, A+2.5, A
+ 5, A+7.5, A+10, wherein A is measuring range lower limit.
Wherein, when the measurement range of the dial caliper guge is 20mm, five selected calibration points are as follows: A, A+5, A+
10, A+15, A+20, wherein A is measuring range lower limit.

20, A+30, A+40, wherein A is measuring range lower limit.
Wherein, when the measurement range of the dial caliper guge is 50mm, five selected calibration points are as follows: A, A+12.5,
A+25, A+37.5, A+50, wherein A is measuring range lower limit.
(3) beneficial effect
The calibration method of the dial caliper guge error of indication, passes through lever-type micrometer and amount provided by above-mentioned technical proposal
Block carries out calibration, easy to operate, efficiently solves the problems, such as the calibration of the dial caliper guge error of indication, improves calibration
Working efficiency, and then guarantee the accuracy of its transmission of quantity value.
Specific embodiment
To keep the purpose of the present invention, content and advantage clearer, below with reference to embodiment, to specific reality of the invention
The mode of applying is described in further detail.
The calibration thinking of the dial caliper guge error of indication of the present invention is: it is used cooperatively using lever-type micrometer and gauge block, it is complete
At the calibration of the dial caliper guge error of indication, first after combined gauges, two measuring jaw measuring surface of lever-type micrometer is contacted with gauge block
It finds turning point and adjusts zero-bit, then operate dial caliper guge, measure its two measuring jaws measuring surface and two measuring jaw of lever-type micrometer
Face contact searches out the indicating value turning point of dial caliper guge, indicating value is read on the dial gauge of dial caliper guge, then the point band
The indicating value of table caliper gauge dial gauge and the difference of corresponding amount block size, the as error of indication of dial caliper guge.
Specifically, the method for the present invention the following steps are included:
S1, the measurement range according to dial caliper guge choose at 1 points, according to measurement corresponding to this five points
Value, is respectively combined out the gauge block of respective value;In five points, one of point is dial caliper guge measurement range lower limit.
S2, selection and the consistent lever-type micrometer of dial caliper guge measurement range;
When S3, calibration, firstly, corresponding dial caliper guge measurement range lower limit is calibrated, specifically: with band Biao Neika
The zero-bit for advising measuring range lower limit adjustment dial caliper guge dial gauge, according to combined gauges size, with two amount of lever-type micrometer
Pawl measuring surface is contacted with combined gauges finds turning point, adjusts lever-type micrometer zero-bit, then operates dial caliper guge, make it
Two measuring jaw measuring surface and lever-type micrometer measure face contact, dial caliper guge indicating value turning point are searched out, in dial caliper guge
Upper reading indicating value, the difference of the dial caliper guge indicating value and corresponding amount block size as correspond to the band Biao Neika of measurement range lower limit
Advise the error of indication.
Then remaining 4 calibration point is corresponded to, repetitive operation as procedure described above records each more corresponding respectively
The dial caliper guge error of indication.
Wherein, table 1 shows gauge block combination corresponding to the dial caliper guge of several different measurement ranges.
Maximum value is the dial caliper guge error of indication in S4, each point error of indication.
Each range calibration dimensional units of table 1: mm
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improve and become
Shape also should be regarded as protection scope of the present invention.
