Abstract
A ring installer and method for installing piston rings on a piston includes an axial pusher, a radial pusher and a translating device. The axial pusher axially moves a cartridge of piston rail rings to position an end rail ring of the piston rail rings into a preinstall position. The radial pusher radially enlarges the end rail ring to separate the end rail ring from the piston rail rings. The translating device receives the end rail ring from the radial pusher and axially moves the end rail ring to an install position that is axially spaced apart from the cartridge of piston rail rings and from the preinstall position wherein the end rail ring is in alignment with a piston groove of the piston.
Claims15
A vehicle piston rail ring installer, comprising:
- an axially movable pusher arranged for axially moving a cartridge of piston rail rings and positioning an end rail ring of the cartridge of piston rail rings in a preinstall position;
- a radially movable pusher device arranged for radially engaging the end rail ring in the preinstall position and separating the end rail ring from the cartridge of piston rail rings by radially expanding the end rail ring into an expanded state, wherein the radially movable pusher device includes at least one pusher that engages the end rail ring on a radially inward side of the end rail ring and the at least one pusher radially moves outwardly to elastically expand the end rail ring radially to the expanded state to initially separate the end rail ring from the cartridge of piston rail rings;
- and
- a translating device arranged for radially receiving the end rail ring in the expanded state from the radially movable pusher device and then axially moving said end rail ring while in the expanded state to an install position wherein the end rail ring is in axial alignment with a piston groove on an associated piston and radially contracts into the piston groove, wherein the translating device includes at least two fingers that each define a groove for accommodating the end rail ring in the expanded state.
A ring installer for installing piston rings on a piston, comprising:
- an axial pusher that axially moves a cartridge of piston rings to position an end ring of the piston rings into a preinstall position;
- a radial pusher that radially enlarges the end ring beyond an original shape to an expanded state to initially separate the end ring from the piston rings without radially contracting the end rail ring, wherein the radial pusher includes at least one pusher that engages the end rail and radially moves outwardly to elastically expand the end rail ring radially;
- and
- a translating device that receives the end ring from the radial pusher in the expanded state without further radial expansion or radial contraction and axially moves the end ring to an install position axially spaced apart from the cartridge of piston rings and from the preinstall position wherein the end ring is in alignment with a piston groove of the piston to allow the end rail ring to elastically contract radially from the expanded state, wherein the translating device includes at least two fingers that each define a groove for accommodating the end rail ring in the expanded state.
