A kind of operation principle of joint part salient point diameter rapid measurement device described in the utility model, such as Fig. 3 to Fig. 5
Shown, during digital control processing joint part, the angle size of salient point a and b or 71 and 72 liang of adjacent side is highly stable, is 90 degree.But
It is due to the abrasion for processing knife grain, diameter D sizes can be changed, it is necessary to which every a period of time measurement once, adjustment knife is mended immediately, is entangled
Positive diameter dimension is in the qualified margin of tolerance.
According to geometrical principle, salient point diameter ab is equal to salient point adjacent edge intersection point diameter cd., i.e. ab=cd.
Ab length change is equal to cd length change, i.e. △ ab=△ cd
According to equilateral right angled triangle principle, he=ce.
He length of the length change equal to ce changes, i.e. △ he=△ ce.
And ce length change is equal to the half that cd length changes, i.e. △ ce=△ cd/2
So as to △ he=△ ce=△ cd/2=△ ab/2
So, can by direct measurement △ he value, come it is simple meet measurement △ ab, that is, the size for measuring salient point diameter D becomes
Change.
In use, making a standard-sized joint part 7 first, the set is developed in the outer face of the joint part 7
The left side of block 3, the left side is used as the locating surface of the joint part 7, the salient point 71 of the joint part 7, the contact of 72 inner conical surfaces
The sliding block 4 simultaneously promotes the sliding block 4, compresses the elastic component 6, and the sliding block 4 moves right, and promotes the height dial gauge
2 measuring probe 20, obtains measured value, and the value dial gauge 2 is returned to zero (to zero), (should as the fiducial value of a standard
Zero) position percentage meter reading is.
With other joint parts positioning planar survey, the measuring probe 20 of the height dial gauge 2 advance or retreat how much
Distance, the height dial gauge 2 will show corresponding reading.Such as described height dial gauge 2 shows 0.02mm (measuring probes
20 move back to the right 0.02mm), then △ he reduce 0.02mm, and now salient point measurement diameter △ ab also just reduce 0.04mm. (△ he
=△ ab/2).
Digital control processing adjustment knife is mended, increase salient point diameter 0.04mm, it is possible to reach diameter dimension intermediate value 16.81mm (with D
Exemplified by=16.81) so that joint part salient point diameter dimension control in the qualified margin of tolerance.
In summary, the only preferred embodiment of the utility model, does not limit protection domain of the present utility model with this, all
The equivalent changes and modifications made according to the utility model the scope of the claims and description, is all that the utility model patent covers
Within the scope of.
