The diameter size calculation method of the object to be measured comprises the following steps:
because the first anvil 2 and the second anvil 3 are symmetrical up and down, only the upper half of the annular measuring bracket 1 needs to be analyzed. As shown in fig. 8, the arc EAC is a contour line where the three clamping positions are located after the measurement of the basic size, the point a is a contact point between the first anvil 2 and the clamping positions, the point C is a contact point between the measuring screw 41 of the dial gauge head 4 and the clamping positions, and the point O1 is a circle center of the three clamping positions of the measuring tool.
The arc FBD is the contour line of the three clamping positions when the actual size is measured, the point B is the contact point between the first anvil 2 and the clamping positions, the point D is the contact point between the measuring screw 41 of the dial gauge head 4 and the clamping positions, and the point O2 is the circle center of the three clamping positions of the object to be measured. The CD length on the graph is the dial indicator head 4 reading. The specific operation steps are as follows:
in the first step, the straight line passing DC intersects with the arc FBD at the point F and intersects with the arc EAC at the point E.
In the second step, AE, AO1, AC, BF, BO2, BD are connected.
And thirdly, making ED parallel lines AJ at the passing point A, intersecting with BF at a point H, intersecting with BO2 at a point I, and intersecting with BD at a point J.
And fourthly, connecting AB, wherein AB is the connecting line of the measuring points of the first anvil 2 after calibration and measurement.
Fifthly, enabling the diameter of the circle O1 to be D1 and the radius to be r1; let the diameter of the circle O2 be D2 and the radius be r2. The first anvil 2, the second anvil 3 and the dial gauge head 4 are circumferentially uniformly distributed on the annular measuring support 1, namely, the angle aed= 60 degrees, the AB is tangential to the circle O2, namely, the angle jbh=90 degrees, and the angle bjh= JBI =30 degrees, the angle bhj= bia=60 degrees, the ji=bi=hi, the hb=hi=ha, and the point H, I is a three-equal division point of AJ. Again cd=aj, aj=ah+hi+ij, ai=bi/sin +.bai= (r 2-r 1)/sin 30 ° =d2-D1.
So cd=3ah=3/2ai=3/2 (D2-D1), i.e. the reading of the dial gauge head 4 is 1.5 times the actual measured diameter difference. Illustrating: the basic diameter is 100, the actual diameter is 101, and the dial indicator reading is 101.5. Because the diameter of the gauge block 5 is known, the diameter of the object to be measured can be obtained by combining the formula according to the degree of the dial gauge head 4.
In addition, preferably, the screw pitch of the adjusting nut 42 of the dial gauge head 4 is reduced by 1.5 times with the screw pitch of the adjusting nut 42 of the ordinary dial gauge head, so that the reading of the dial gauge head 4 is the diameter of the clamping position of the part to be measured, and the calculation by a formula is not needed, so that the operation is convenient.
