Claims

[Scope of utility model registration request]

A motor 12, a crankshaft 15 connected to the motor 12 to convert the rotational motion of the motor 12 into linear motion, a crank 16 connected to the crankshaft 15 to move linearly, and a tool holder 19 supporting the cutting tool 20. , a flapper 18 that supports the tool holder 19 so as to be movable up and down relative to the workpiece, a flapper mounting plate 17 that is connected to the crank 16 and supports the flapper 18 in a swingable manner, a positioning metal 27 that supports the workpiece, and a positioning metal 27 that supports the workpiece. Face cam 2 is placed in close proximity to the metal 27, facing each other in the horizontal direction.
8, and a drive device 1 that rotationally drives the face cam 28 and moves the face cam 28 in a direction away from or toward the positioning metal 27.
1 and 29, the front end side of the flapper 18 is in contact with a flapper cam 22 fixed to the flapper mounting plate 17 and having a step in the axial direction of the crankshaft 15 on an extension line of the crankshaft 15,
The outer diameter groove cutting machine is characterized in that the contact surface with the positioning metal 27 is formed as an eccentric surface having gradually different lengths in the axial direction.
