文档介绍：数控车床的六角回转刀架的机构设计
摘要
本文主要研究数控车床的六角回转刀架的机构结构和动作原理。六角回转刀架主要分为分度机构、液压机构、精定位机构三大机构。分度机构负责刀架的主要动作,精定位机构决定了刀架重复定位的精度。本文拼提出一套可行的设计方案,并就分度机构和精定位机构进行详细的研究和设计。其中分度机构的核心设计方案采用端齿盘离合器,精定位机构的核心设计方案采用插销机构。最终,完成了数控车床的六角回转刀架的机构设计。

The instiution design of turret carriage
ABSTRACT
Production e more efficient and the pursuit of the machine tool change process automation es necessary, a variety of automatic tool changer came into being. The most representative is hexagonal rotating turret, it is economical and practical.
This paper studies the institutional structure and operation principle of the hexagonal rotating turret of lathe .The hexagonal rotating turret is divided into sub-degree rotating turret part, hydraulic pressure part, the final precise positioning mechanism part. The sub-degree rotating turret part makes the turret turning ,the final precise positioning mechanism part determines the repeat positioning accuracy of turret. This paper proposes a viable spell design, and make main design on sub-degree institutions and the final positioning mechanism for detailed study .and design of sub-degree institutions where the core design with the crown wheel clutch, precision positioning mechanism with bolt part core design . pleted the instiution design of hexagonal rotating turret .
Keywords: instiution ;design ;turret ;carriage
