An indexing device comprising a base table (10), a turret (11) which indexes about a given rotary center relative to the base table (10), a pair of positioning engaging members (27) provided between the base table (10) and the turret (11), wherein at least one of the positioning engaging members (27) has an inclined tooth profile, and the positioning engaging members (27) are engageable with and disengageable from each other relative to the tooth profiles when they move in axial directions thereof relative to each other. The meshing of the tooth profiles are maintained by applying a pressing force to at least one of the positioning engaging members (27). When the turret (11) receives a load, a positioning displacement which occurs between the pair of positioning engaging members (27) is detected, and the pressing force applied to the positioning engaging members (27) is adjusted based on the result of detection.
An indexing device comprising a base table, a rotary table which indexes about a given rotary center relative to the base table, a pair of positioning engaging members provided between the base table and the rotary table, at least one of said positioning engaging members having inclined tooth profiles, said positioning engaging members being engageable with and disengageable from each other relative to said tooth profiles when said positioning engaging members move in axial directions thereof relative to each other, and a pressing means for pressing at least one of said pair of positioning engaging members in the axial direction thereof to permit one of said positioning engaging members to engage with the other positioning engaging member, wherein said indexing device further comprises:
A method of controlling an indexing device comprising a base table, a rotary table which indexes about a given rotary center relative to the base table, a pair of positioning engaging members provided between the base table and rotary table, at least one of said positioning engaging members having inclined tooth profiles, said pair of positioning engaging members being engageable with and disengageable from each other relative to said tooth profiles when said positioning engaging members move in axial directions thereof relative to each other, wherein said method comprises:
