數(shù)控車床的六角回轉(zhuǎn)刀架的機(jī)構(gòu)設(shè)計(jì)

摘要

本文主要研究數(shù)控車床的六角回轉(zhuǎn)刀架的機(jī)構(gòu)結(jié)構(gòu)和動(dòng)作原理。六角回轉(zhuǎn)刀架主要分為分度機(jī)構(gòu)、液壓機(jī)構(gòu)、精定位機(jī)構(gòu)三大機(jī)構(gòu)。分度機(jī)構(gòu)負(fù)責(zé)刀架的主要?jiǎng)幼?，精定位機(jī)構(gòu)決定了刀架重復(fù)定位的精度。本文拼提出一套可行的設(shè)計(jì)方案，并就分度機(jī)構(gòu)和精定位機(jī)構(gòu)進(jìn)行詳細(xì)的研究和設(shè)計(jì)。其中分度機(jī)構(gòu)的核心設(shè)計(jì)方案采用端齒盤離合器，精定位機(jī)構(gòu)的核心設(shè)計(jì)方案采用插銷機(jī)構(gòu)。最終,完成了數(shù)控車床的六角回轉(zhuǎn)刀架的機(jī)構(gòu)設(shè)計(jì)。

The instiution design of turret carriage

ABSTRACT

Production become more efficient and the pursuit of the machine tool change process automation becomes 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 . Finaly completed the instiution design of hexagonal rotating turret .

Keywords: instiution ；design ；turret ；carriage
