The deflection that spring 17 occurs when measuring identical size is the same, and the elastic force, that is, measuring force formed is with regard to identical, to guarantee to measure
The consistency of power improves the accuracy of measurement.
The utility model solve the technical issues of first is that it is described surely measurement arm 3 and the dynamic measurement arm 4 can be by user
It is replaced, since calliper two measurement arm lengths R value errors will have a direct impact on the measurement accuracy of calliper, to solve above-mentioned ask
Topic, the utility model have also done following design: the support 7 is equipped with by positioning the position for measuring arm 3 surely to protect
The consistent positioning column 18 of length R of the measurement arm 3 surely and the dynamic measurement arm 4 is demonstrate,proved, the positioning column 18 is in the branch
Bulge-structure on seat 7, the arm 3 of measurement surely are mounted on the position of one end on the support 7 and the corresponding positioning column 18
Place is equipped with mounting hole corresponding with the positioning column 18.It first ensure that measurement arm 3 and the dynamic survey surely when processing
Measurement length, that is, R the value for measuring arm 4 is consistent, since the dynamic measurement arm 4 is mounted in the shaft 9, it is therefore desirable to described fixed
It is consistent that measurement arm 3 plays the role of the R value that a positioning both just can guarantee, therefore in positioning column when the installation arm 3 of measurement surely
Position is determined under the action of 18 positioning, thus the measurement arm 3 surely and the dynamic R for measuring arm 4 after just can guarantee installation
It is worth consistency.Surely for the measurement arm 3 on the positioning column 18 of the support 7, the positioning column 18 measures arm 3 to described surely
The distance for determining measuring head is equal to R value.The advantages of above design, is: reducing the assembly difficulty of measurement arm, guarantee is described to measure arm 3 surely
With the consistency of the R value of the dynamic measurement arm 4, arm is measured without influencing precision so as to easily be replaced by user.
If the calliper ontology is L in measurement length1Standard gauge block when, the dynamic measurement arm 4 is relatively described to determine measurement
The angle that arm 3 is formed is α.Surely the length of the measurement arm 3 and the dynamic measurement arm 4 is R.The single-chip microcontroller 1 also has such as
Lower function:
The single-chip microcontroller 1 is also used to after the length R for individually adjusting the measurement arm 3 surely and the dynamic measurement arm 4, to length
Degree R and angle α are demarcated to adjust the measurement range of the calliper ontology.
Alternatively, the single-chip microcontroller 1 is also used to individually adjusting the relatively described position for measuring arm 3 surely of dynamic measurement arm 4
Afterwards, length R and angle α are demarcated to adjust the measurement range of the calliper ontology.
Alternatively, the single-chip microcontroller 1 be also used to adjust at the same time it is described surely measurement arm 3 and it is described it is dynamic measurement arm 4 length R with
And behind the relatively described position for measuring arm 3 surely of dynamic measurement arm 4, length R and angle α are demarcated to adjust the card
The measurement range of gauge.
As shown in fig. 6, the single-chip microcontroller 1 demarcates the length of the measurement arm 3 surely and the dynamic measurement arm 4 by the following method
Spending R and measurement length is L1The angle α that the relatively described arm 3 of measurement surely of the dynamic measurement arm 4 of Shi Suoshu is formed:
Step 1, measurement length are L1And L2Standard gauge block: when measurement length be L1Standard gauge block when, the sensing
Device exports the angle [alpha] of the dynamic measurement 4 position relative sensors absolute zero position of arm1To the single-chip microcontroller 1；When measurement length
For L2Standard gauge block when, the sensor export it is described it is dynamic measurement 4 position relative sensors absolute zero position of arm angle [alpha]2
To the single-chip microcontroller 1, the single-chip microcontroller 1 according to trigonometric function and by following formula calculate it is described surely measurement arm 3 with it is described
The length R and measurement length of dynamic measurement arm 4 are L1The angle α that the relatively described arm 3 of measurement surely of the dynamic measurement arm 4 of Shi Suoshu is formed:
Wherein β=α2-α1；
The length R being calculated and the angle α are stored completion calibration by step 2, the single-chip microcontroller 1.
As shown in fig. 7, the calliper ontology is in the size of L dimension on measuring measured object 19, the single-chip microcontroller 1 is being marked
The fixed length R and the angle α and then dynamic 4 place of measurement arm when measuring L exported according to the sensor
Position A, measurement L1Position B where the dynamic measurement arm 4 of Shi Suoshu, obtains the angle, θ that position A is rotated relative to position B, most
Measurement result L is calculated by following formula afterwards:
Different form, the measurement arm of different length determine the measurement occasion and measurement range of calliper, and the utility model is logical
Cross the length R for replacing the measurement arm 3 surely and the dynamic measurement arm 4 to adjust the measurement arm 3 surely and the dynamic measurement arm 4.
When measurement arm is fixed, the relatively described position for measuring arm 3 surely of the dynamic measurement arm 4 is (described when unmeasured to measure arm 3 and institute surely
State the angle that measurement arm 4 opens naturally), i.e., the corner dimension that the two is formed determines the measurement range of calliper, as adjustment
The relatively described relative position for measuring arm 3 surely of dynamic measurement arm 4, is realized by following methods: dismantling lower rear cover from support 7
8, make exposure in place of the connection of the dynamic measurement arm 4 and the shaft 9.Since the dynamic measurement arm 4 is removable by transition fit
That unloads is mounted in the shaft 9, and transition fit refers to the cooperation that may have gap or interference, at this time hole (dynamic measurement 4 end of arm
Mounting hole) tolerance range and axis (shaft 9) tolerance range it is mutually overlapping, i.e., described in the described dynamic measurement arm 4 can be installed at any time
It is disassembled in shaft 9 or from the shaft 9.Therefore, first the dynamic measurement arm 4 is disassembled from the shaft 9, so
The angle that the relatively described position for measuring arm 3 surely of dynamic measurement arm 4 i.e. the two is formed is adjusted again afterwards, until the folder that the two is formed
After the measurement range of angle and needs matches, then change the posture after angle with the dynamic relatively described shaft 9 of measurement arm 4, it will
The dynamic measurement arm 4 realizes being fastenedly connected for the two after being assembled at the corresponding position of the shaft 9, so that described
The dynamic relatively described position for measuring arm 3 surely of measurement arm 4 changes.Either replace measurement arm 3 and the dynamic measurement surely
Arm 4 adjusts the length R of the measurement arm 3 surely and the dynamic measurement arm 4, or the adjustment dynamic measurement arm 4 is relatively described fixed
It behind the position for measuring arm 3, is required to just measure after selecting suitable standard gauge block to carry out above-mentioned proving operation, pass through
The length R and the dynamic measurement arm 4 of the calibrated adjustable measurement arm 3 surely of calliper and the dynamic measurement arm 4 are with respect to institute
The position for stating fixed measurement arm 3, realizes the adjustable of calliper measurement range, expands the scope of application of calliper, and also improve measurement
Precision.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
