OUTER DIAMETER MEASURING APPARATUS CYLINDRICAL MACHINE PARTS

摘要

The present invention relates to a device for measuring the outer diameter of a cylindrical machine part and, more specifically, to a device for measuring the outer diameter of a cylindrical machine part to measure the cylindrical machine part accurately by an angle formed on a holder. The holder is fixed to the lower end of a handle, is directly in contact with the cylindrical machine part, and is formed at an angle of 37-39°. The present invention can perform accurate measurement by the angle formed on the holder and mass repeated measurement, be portable, and be mass-produced with a simple structure.
