Claims

[Scope of utility model registration request]

The circular hole is slidably fitted into one of a pair of circular holes formed on the coaxial line of the workpiece, and a plurality of tapered rollers of the same size are oriented circumferentially and parallel to the axis of the circular hole. In a taper machining device, a mandrel is provided with a holding cylinder which is slidably held in the holding cylinder via a corresponding slit so as to be movable forward and backward in the radial direction of the mandrel, and has a tapered portion that engages with each taper roller from the inside. , the proximal end of the mandrel is slidably mounted on the tip of the shaft of the drive device via a resilient spring, and can be freely engaged with and disengaged from a stopper of the shaft, while the holding cylinder is resiliently compressed against the workpiece holder. A taper processing device characterized in that it can be freely engaged and disengaged via a spring.
