Gear processing apparatus and phase matching apparatus for gear work

摘要

To provide a gear processing apparatus having a simple structure.SOLUTION: The gear processing apparatus is provided with a processing section for processing the gearwork 35. The workpiece exchanging apparatus 63 is provided with a grip part 67 for gripping the gearwork 35. The grip part 67 has a phase matching pin 69 that can be retracted and retracted and a spring 70 that urges the phase matching pin 69 in the projecting direction. As the phase matching pin 69 enters into the tooth groove of the gearwork 35, the phase of the gearwork 35 is matched.(FIG.
