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 I ABSTRACT II 1 1.1 1 1.2 2 1.3 3 1.4 4 1.5 5 6 2.
