Title:
INDEXING APPARATUS AND METHOD FOR CONTROLLING THE INDEXING APPARATUS
Document Type and Number:
WIPO Patent Application WO/1998/025730
Kind Code:
A1
Abstract:
An indexing apparatus comprises a base (10), a turret (11) which indexes a work about a predetermined rotation axis with respect to the base (10), and a pair of positioning engagement members (27) provided between the base (10) and the turret (11). At least one of the positioning engagement members (27) has an inclined tooth, and they can engage with and disengage from each other via the tooth by the axial relative movement of the positioning engagement members (27). The state of tooth engagement between the members (27) is held by applying a pressure to at least one of the pair of positioning engagement members (27). When the turret (11) is subjected to a load, the positional deviation between the pair of positioning engagement members (27) is detected, and the pressure against the pair of positioning engagement members (27) is adjusted on the basis of the detection result.
