摘要： An installation device includes an extruding mechanism that horizontally extrudes a piston ring, positions the piston ring and, after extruding, is driven downwardly and then returned to a waiting position; a ring holding mechanism that has a guide passage for guiding the 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 insertion of the piston; a ring diameter extending mechanism that extends the diameter of the piston ring, that is driven to enter and leave 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 that holds the piston at a predetermined position.

摘要： 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.
