TURRET TOOL REST

摘要

Positioning engaging members (27) are provided between a base table (10) and a turret (11) which is indexed relative to the base table (10) by a driving force of an indexing/tool turning motor (32) so as to be engageable with or disengageable from each other. The positioning engaging members (27) engage with each other to prevent the turret (11) from turning. Further, the driving force of the indexing/tool turning motor (32) is transmitted or not transmitted to the turret (11) by clutch pieces (31). The driving force of the indexing/tool turning motor (32) is transmitted to a turning tool (14) mounted on tool mounting portions (12) of the turret (11) via a power transmission member. The positioning engaging members (27) engage with or disengage from each other by an engaging means. Further, the engaging means interlocks with the disengagement between the positioning engaging members (27) to permit the clutch pieces (31) to engage with each other while the engaging means interlocks with the engagement between the positioning engaging members (27) to permit the clutch pieces (31) to disengage from each other. <IMAGE>
