Abstract

The utility model provides a tool for installing piston ring, which relates to an installation tool for installing the piston cylinder and piston on the piston cylinder of the diesel engine, the gasoline engine, the hydraulic cylinder, the pneumatic cylinder. The tool for installing piston ring is designed as a casing tube; the inner diameter of the casing tube is a taper, the pore diameter at one end of the casing tube is same as the pore diameter of the piston cylinder, and the pore diameter at other end of the casing tube is larger than the outer diameter of the piston ring. When installed, the piston ring is mounted on the piston firstly, and the piston ring is put in the butt of the utility model secondly; the end with the piston ring is positioned upward, the piston ring and the piston are installed in the piston cylinder by the hands presses the piston after the little end aims to the piston cylinder of the diesel engine, the gasoline engine, the hydraulic cylinder and the pneumatic cylinder.

Description

The erecting tools of piston ring

One, technical field:

The utility model relates to the piston cylinder ring installation of diesel engine, gasoline engine, hydraulic cylinder, steam-operating cylinder and the instrument of piston.

Two, background technology:

At present, the piston cylinder of diesel engine, gasoline engine, hydraulic cylinder, steam-operating cylinder all needs piston is installed into, piston ring is arranged on the piston, during installation, earlier piston ring is placed in the piston ring groove on the piston, with hand that Huo Sai Huan Pinch is tight, at leisure it is put in the piston cylinder mouth with bottle opener then, with wooden stick the piston ring on piston and the piston is beaten at last and enter piston cylinder; Send in the piston cylinder mouth after perhaps piston ring being packed tightly, enter in the piston cylinder after beaing with wooden mallet again with iron sheet.Because on the piston a plurality of piston rings are arranged, this just need repeatedly repeat above-mentioned action, piston and piston ring could be placed in the piston cylinder.In the process of installing, the one, easily piston ring is damaged when beaing with wooden mallet, make piston ring breakage even; The 2nd, pretty troublesome when installing, Yong Shou Pinch piston ring or be easy to make piston ring play on piston during with iron sheet bag piston ring is not easy the location, therefore, is difficult to piston ring is installed in the piston cylinder.

Three, goal of the invention:

The purpose of this utility model is to provide a kind of erecting tools of ring installation, and it can make piston ring and piston be installed in the piston cylinder rapidly, and neither damages piston ring, can also reach laborsaving, simple purpose.

Four, summary of the invention:

Feature of the present utility model is a sleeve pipe (1), and sleeve pipe (1) internal diameter is taper, and the end (2) in the sleeve pipe (1) is identical with the internal diameter size of piston cylinder, and the other end (3) in the sleeve pipe (1) is greater than the piston ring external diameter.

During installation, earlier piston ring is installed on the piston, in the big end of the present utility model of then piston ring and piston being packed into, again its small end is aimed at the piston cylinder of diesel engine or gasoline engine or hydraulic cylinder or steam-operating cylinder, press piston with light finger again, piston ring and piston can enter in the piston cylinder.

The utility model has the advantages that:

When piston ring and piston are installed into piston cylinder, do not need to beat with wooden mallet, also need be with bottle opener and iron sheet location, therefore, laborsaving during installation, convenient, fast; Simultaneously, can not damage or make piston ring breakage because of beaing with wooden mallet yet.

Five, description of drawings:

Accompanying drawing 1, the utility model structural representation Fig. 1;

Accompanying drawing 2, the utility model structural representation Fig. 2.

Six, the specific embodiment:

Among Fig. 1-2, with 175 diesel engines is example, its cylinder diameter is 75mm, the external diameter of ring is 80mm, the external diameter of sleeve pipe of the present utility model (1) is 90mm, the internal diameter of the end (2) in the sleeve pipe (1) is 75mm, the internal diameter of the other end (3) is 85mm, and piston ring is divided into oil ring and compression ring, in the annular groove of the piston ring of earlier oil ring and vapour ring being packed into, again with each oil ring, the collar extension of vapour ring staggers mutually, to encircle again inject put into sleeve pipe (1) behind the clear great machine oil and make have on the piston piston ring one end in (3), piston then will (2) aligning piston cylinder in (2), press piston with have gentle hands again, piston ring and piston promptly enter in the piston cylinder.

Claims

A kind of erecting tools of piston ring, relate to the piston ring of the piston cylinder on diesel engine, gasoline engine, hydraulic cylinder, the steam-operating cylinder and the erecting tools of piston, it is characterized in that: it is a sleeve pipe (1), the internal diameter of sleeve pipe (1) is taper, end (2) in the sleeve pipe (1) is identical with the internal diameter size of piston cylinder, and the other end (3) is greater than the external diameter of piston ring.
