Claims

[Scope of utility model registration request]

a housing, a table shaft rotatably supported by the housing, an index table fixed to the table shaft, a drive plate fixed concentrically to the outer periphery of the table shaft, and a first index table.
an indexing gear provided on the outer periphery of the table shaft so as to be movable in the axial direction, a ring gear rotatably driven by the indexing drive means and capable of being engaged with and disengaged from the drive plate; a ring plate provided to be movable in the axial direction together with the ring gear; a second index gear fixed to the ring plate and capable of engaging and disengaging from the first index gear; and a second index gear provided parallel to the table axis. At the same time, one end is connected to the ring plate and driven back and forth by the switching drive means,
a drive shaft that selectively switches the engagement state between the drive plate and the ring gear and the engagement state between the first index gear and the second index gear; and a drive shaft provided on the outer periphery of the drive shaft; An indexing device comprising a hydraulic clamper that clamps a drive shaft.
