Claims

[Scope of utility model registration request]

A pendulum is attached to the machine base by a support bolt so as to control the engraving movement in the arc direction of the inner circumferential surface of the ring, and a support horizontally orthogonal to the pendulum so as to control the engraving movement in the width direction of the inner circumferential surface of the ring. It consists of a base moving rod whose upper end is pivotally supported on a shaft, a copying needle vertically supported at a lower part of the base moving rod, and an engraving shaft having an engraving needle attached at an upper part of the base moving rod, The copying needle is operated by copying the copying letters on the model board placed directly below the copying needle, and the engraving needle is operated at a constant reduction rate relative to the amount of operation of the copying needle to engrave the letters on the inner circumferential surface of the ring. In the ring engraving machine, the intersection of the support bolt and the support shaft and the axes of the engraving needle and copying needle are arranged on the same line, and a model plate is formed into a rectangular shape and a guide is provided on the base of the machine stand. When the model board is slidably provided in the groove in the left and right direction, and the copying characters are arranged on a line spaced a predetermined distance from the front and back edges of the model board with the same line as the center, and the model board is inserted into the guide groove. , a ring engraving machine configured so that the tip of a copying needle and the center line of a copying character are aligned.
