Utilize above-mentioned measurement mechanism and propose a kind of counterbore angle measurement method, it comprises the steps:
The first step, estimate the angle degree sentencing counterbore, the adjustment relevant position of vernier 5 on numerical value main scale 6, makes the angle formed between the first sounding rod 1 and the second sounding rod 2 be estimate the counterbore angle sentenced, is now fixed on numerical value main scale 6 by vernier 5 by tightening screw 51;
And when needing the counterbore angle value measured to mark, but when needing to verify that whether the angle value that provided correct, estimate so the angle degree sentencing counterbore be now to angle value, according to formula two:
The Length Indication groove 53 obtained on vernier refers to the position x on length scale line 62, angle between the first sounding rod 1 now and the second sounding rod 2 is the counterbore angle value estimated and sentence, wherein in formula two, x is that the Length Indication groove 62 of vernier 5 refers to the position on the length scale line 62 of numerical value main scale 6, a is measurement pin joint that unit is identical with the unit of length scale line 62 to first by the distance of the hinged place of lever 4 and the second sounding rod 1, θ be made as unit with angle estimate the angle degree sentencing counterbore, α is the angular values being made as maximum angle between the first sounding rod 1 of unit and the second sounding rod 2 with angle, the position x of the length scale line 62 that last basis draws determines the displacement of vernier 5, so determine the angled relationships between the first sounding rod 1 and the second sounding rod 2,
Second step, measures on seamed edge 11 and the second measurement seamed edge 21 first and evenly applies the coloring agent that can wipe easily;
3rd step, servo-actuated angle component is close to counterbore and with its gentle touchdown, the first measurement seamed edge 11 and the second coloring agent measured on seamed edge 21 is made to be imprinted on the inwall of counterbore, need the inwall repeatedly servo-actuated angle component being removed counterbore afterwards, and fine rotation and the servo-actuated angle component of swing, and then servo-actuated angle component is close to counterbore and with its contact internal walls;
4th step, check by dye to counterbore inwall on coloring agent lines, and judge that whether the counterbore angle value estimated in the first step accurate;
If there is a pair with two chromonemas of counterbore center line symmetry, and these two lines extend to its inner edge from the outer most edge of counterbore inwall incessantly, and the corner dimension so between the first sounding rod 1 and the second sounding rod 2 just in time equals counterbore angle;
If there is no aforementioned continual symmetrical chromonema, then be divided into two kinds of situations, for there is not continual symmetrical chromonema in the first, simultaneously basic only near the outer most edge of counterbore aperture inwall with the chromonema that counterbore center line is symmetrical, do not extend to its inner edge, the angle so at this moment between the first sounding rod and the second sounding rod is then greater than the angle of counterbore; For there is not continual symmetrical chromonema in the second, and with the symmetrical chromonema of counterbore center line mostly only near the inner edge of counterbore aperture inwall, do not extend to its outer most edge, the angle so at this moment between the first sounding rod and the second sounding rod is less than the angle of counterbore;
When angle between the first sounding rod 1 and the second sounding rod 2 is equal with the angle of counterbore, enter the 6th step; And the angle of angle between the first sounding rod 1 and the second sounding rod 2 and counterbore unequal time, enter the 5th step;
5th step, wipes the coloring agent of counterbore inwall and repeats the step of the first step to the 4th step;
6th step, reads the numerical value of the angle index line 61 now indicated by vernier 5 upper angle index line 52, by coordinating the length scale line 62 set up to draw length value now with this angle index line 61, then according to formula one:
Measured counterbore angle value θ can be drawn, wherein in formula one, θ is the measured counterbore angular values being made as unit with angle, a is measurement pin joint that unit is identical with the unit of length scale line 62 to first by the distance of the hinged place of lever 4 and the second sounding rod 1, and α is the angular values being made as maximum angle between the first sounding rod 1 of unit and the second sounding rod 2 with angle.
The foregoing is only the preferred embodiment of the invention; not in order to limit the invention; within all spirit in the invention and principle, any amendment done, equivalent replacement, improvement etc., within the protection domain that all should be included in the invention.
