    • The invention provides an installation device and an installation method for a piston ring. The installation device includes an extruding mechanism (110) that horizontally extrudes a piston ring (R) andpositions the piston ring at apredetermined position and, after extruding the piston ring, is driven downwardly in a vertical direction by a predetermined amount and is then returned to a waiting position; a ring holding mechanism (120) that has a guide passage for guiding the extruded piston ring, that is driven so as to move close to and apart from a piston in one direction perpendicular to the extruding direction, and that is capable of defining an insertion hole for inserting the piston in the center area thereof; a ring diameter extending mechanism (130) that extends the diameter of the piston ring, that is driven in a state of entering and leaving the guide passage of the ring holding mechanism, and that is reversely driven to a position for defining a part of the guide passage when the diameter-extended state of the piston ring is released; and a piston holding member (140) that holds the piston at a predetermined position. Thus, the piston ring can be reliably installed.
    • 本发明提供一种用于活塞环的安装装置和安装方法。 安装装置包括:挤压机构(110),其水平地挤压活塞环(R)并将活塞环定位在预定位置,并且在挤压活塞环之后,沿垂直方向向下驱动预定量,然后返回到 一个等待的位置 环形保持机构(120),其具有用于引导挤出的活塞环的引导通道,该引导通道被驱动以在与挤出方向垂直的一个方向上靠近和离开活塞移动,并且能够限定插入 用于将活塞插入其中心区域的孔; 环形直径延伸机构(130),其延伸所述活塞环的直径,所述直径延伸机构(130)在进入和离开所述环保持机构的引导通道的状态下被驱动,并被反向驱动到用于限定所述环形部分的一部分的位置 当活塞环的直径伸展状态被释放时,引导通道; 以及将活塞保持在预定位置的活塞保持构件(140)。 因此,可以可靠地安装活塞环。
