Description

Automatic circumference measuring instrument

Technical Field

The utility model belongs to the technical field of measuring equipment, and particularly relates to an automatic perimeter measuring instrument.

Background

Because the wall thickness of the opening of the seal head is different from the wall thickness of the cylinder, if the outer wall is aligned, the inner wall has the dislocation condition, the inner wall of the container has the geometric discontinuity condition, and the bearing of the container is not facilitated, so most containers are required to have the same inner surface when the cylinder and the seal head are axially assembled, the inner circumference needs to be measured, and the inner circumference of the cylinder and the inner circumference of the seal head are ensured to be consistent, so that the dislocation of the inner wall of the container is avoided.

The circumference can not be accurately calculated by the diameter calculation method because the circumference is not standard round after the end socket and the cylinder body are formed, and elliptical and irregular round conditions exist, so the circumference calculation method by measuring the diameter is inaccurate, and the circumference is determined only by an actual measurement method. In the past, when the manual measurement of the inner circumference of the seal head is carried out, 2 persons are matched, firstly, the initial point is recorded on the inner circumference of the opening of the seal head, then the initial point is zeroed with the steel disc ruler, the steel disc ruler is gradually pressed on the inner side of the circumference of the opening of the seal head along the scale direction, and the circle is coiled to the initial point, so that the inner circumference data of the seal head is obtained, and the measurement is very inconvenient.
