Assembling tool for piston ring

Abstract

The invention discloses an assembling tool for a piston ring, and relates to the field of air cylinder assembling. The assembling tool comprises a sleeve; a protective cover is fixedly connected to the top of the sleeve; a cylinder sleeve is arranged in an inner cavity of the sleeve; the cylinder sleeve is closely attached to the inner side wall of the sleeve; a cylinder cover is arranged at the top of the cylinder sleeve; the bottom of the side wall of the cylinder cover is sleeved with the piston ring; a guide pull rod is fixedly connected to the center of the top of the cylinder cover; a piston column is movably connected to the top of the cylinder cover; a movable hole matched with the piston column is formed in the surface of the guide pull rod; the piston column penetrates through the guide pull rod through the movable hole; a threaded rod is fixedly connected to the bottom of the cylinder cover; and a through hole matched with the threaded rod is formed in the center of the bottom of the sleeve. According to the assembling tool, after the surface of the cylinder cover is sleeved with the piston ring, the threaded rod is mounted, the cylinder sleeve is placed into the sleeve,when the cylinder cover is inserted into the cylinder sleeve, the threaded rod extends out of the bottom of the sleeve, the cylinder sleeve and the piston ring are concentric through the whole tool,the situation that the deformation degree of the edge of the piston ring is different in the assembling process is avoided, and tool is easy and convenient to operate.

Description

technical field [0001] The invention relates to the field of cylinder assembly, in particular to a piston ring assembly tool. Background technique [0002] Piston rings are metal rings used to embed in piston grooves. Piston rings are divided into two types: compression rings and oil rings. The compression ring is used to seal the combustible mixture in the combustion chamber; the oil ring is used to scrape excess oil from the cylinder. The piston ring is a metal elastic ring with a large outward expansion deformation, which is assembled into the corresponding annular groove of the section. The reciprocating and rotating piston rings rely on the pressure difference of gas or liquid to form a seal between the outer circular surface of the ring and the cylinder and one side of the ring and the ring groove. [0003] The conventional piston ring assembly is to put the piston ring on the cylinder head, align the cylinder head with the through hole on the surface of the cylinder...

AI Technical Summary

Problems solved by technology

[0003] The conventional piston ring assembly is to put the piston ring on the cylinder head, align the cylinder head with the through hole on the surface of the cylinder liner, and squeeze it hard downward, so that the end of the cylinder head with the piston ring is embedded in the cylinder liner. If the operation is not familiar, the ring edge of the piston ring will be abnormally deformed, and it will not be able to fit well with the cylinder liner, resulting in air leakage
