The place of industry has been more difficult to；Although some equipment with one-handed performance, but can only be measured external diameter and maybe can only measure internal diameter, it is suitable for
Face is less.
Summary of the invention
In order to solve above-mentioned technical problem present in prior art, the invention provides a kind of pipe internal-and external diameter and measure
Instrument, including three rollers, two measurement arms and angular displacement sensor, measures arms for two and is rotatably connected, and junction arranges it
In a roller, two measure arms outer ends another one roller is respectively set, roller by wheel shaft be fixed to measurement arm on, and
Can roll, the spacing between two axle holes measuring arm is equal.
Further, described angular displacement sensor is disposed therein on a measurement arm.
Further, described angular displacement sensor is provided with locking bolt, is measuring arm for lock angle displacement transducer
Position.
Further, the shape of described measurement arm is linear type, shaped form or circular arc.
Present invention also offers the outer routing method of a kind of pipe, comprise the steps:
1) roller by described internal-and external diameter measuring instrument two measuring arm outer end is close, is returned to zero by angular displacement sensor；
2) three rollers are close to cylindrical to be measured；
3) the angle value a of angular displacement sensor is read；
4) being calculated as follows out the overall diameter of circle to be measured, computing formula is:, L is two measurements
The half of the axle hole spacing of arm, R is the diameter of roller.
Present invention also offers a kind of round tube inside diameter method, comprise the steps:
1) roller by described internal-and external diameter measuring instrument two measuring arm outer end is close, is returned to zero by angular displacement sensor；
2) the three of measuring instrument rollers are close to inner circle to be measured；
