Very little survey tool.
A kind of survey tool for being used to measure steel-casting irregular holes class formation inside dimension, including the first measuring arm,
Second measuring arm, the first regulating arm, the second regulating arm, dial, one end of the first measuring arm are contacted with hole inner wall, and first surveys
The other end of amount arm is flexibly connected with one end of the first regulating arm, so that the first measuring arm turns relative to the first regulating arm is opposite
Dynamic, one end of the second measuring arm is contacted with hole inner wall, and one end activity of the other end of the second measuring arm and the second regulating arm is even
Connect, so that the second measuring arm is relatively rotated relative to the second regulating arm, the other end of the second regulating arm is another with the first regulating arm
One end is flexibly connected so that the second regulating arm and the first regulating arm relatively rotate, dial be movably connected in the first regulating arm and
Between second regulating arm, scale marker is set, to record the first regulating arm and the second regulating arm by scale marker on dial
Between spacing.
The length of the first measuring arm and the second measuring arm in the present invention can be adjusted arbitrarily, and angular adjustment maximum magnitude exists
180°；60 ° of the adjusting angle maximum angle of first regulating arm and the second regulating arm, two resultant effects fully achieve clamp
180 ° of measurements；To the control of irregular hole size measurement accuracy within ± 1mm, accuracy improves 50%；Time of measuring saving
More than 90%, efficiency improves 90%；It can also not measured accurately by line for intricate casting endoporus.
