Description

Technical Field

[0001] The utility model belongs to the field of installation devices, and in particular relates to an automatic installation device for a piston gas ring. Background Art

[0002] The piston ring is a metal ring that is embedded in the piston groove. There are two types of piston rings: compression rings and oil rings. The compression ring can be used to seal the combustible mixture in the combustion chamber; the oil ring is used to scrape off excess oil on the cylinder.

[0003] The piston ring is a metal elastic ring with a large outward expansion deformation. It is assembled into the cross section and the corresponding annular groove. The reciprocating and rotating piston ring forms a seal between the outer surface of the ring and the cylinder and between the ring and one side of the ring groove by relying on the pressure difference of the gas or liquid.

[0004] When installing the piston air ring in the prior art, it is mostly necessary to manually pry the piston air ring apart and then put the piston air ring on the piston. However, when manually installing the piston air ring, it is impossible to install the piston air ring in the groove on the piston at one time. When the piston air ring is manually pushed to move on the piston, it will scratch the piston, thereby affecting the service life of the piston. Therefore, an automatic piston air ring installation device is needed. Utility Model Content
