Problems solved by technology

[0002] In the existing piston ring assembly process, the piston ring is usually opened by manpower or other piston ring opening tools so that it can be stretched and inserted into the piston body and embedded in the piston ring groove, which results in low installation efficiency and labor intensive labor. The strength is very high, and at the same time, it is difficult to control the human strength in a balanced manner, and it is easy to break or strain the piston ring

Abstract

The invention provides a tool capable of installing a piston ring. The tool comprises a rack, a piston placement mold arranged on the rack, a tapered guide mold, a piston ring squeezing mechanism arranged on the rack, and a drive mechanism for driving the piston ring squeezing mechanism. A piston is placed on the piston placement mold, the tapered guide mold is placed on the top part of the piston, a control box button controls to enable the drive mechanism to act, the piston ring squeezing mechanism presses the piston ring to downwards move along the tapered guide mold and be stressed to expand, and finally the piston ring shrinks to clamp in a slot in the piston. The device is simple in structure, high in automation degree, capable of improving the efficiency in installing the piston and reducing the labor intensity, and capable of preventing the occurrence of the phenomenon that the piston ring is damaged during an installation process.

Description

technical field [0001] The invention relates to the field of mechanical tools, in particular to a piston ring installation tool. Background technique [0002] In the existing piston ring assembly process, the piston ring is usually opened by manpower or other piston ring opening tools so that it can be stretched and inserted into the piston body and embedded in the piston ring groove, which results in low installation efficiency and labor intensive labor. The strength is very high, and at the same time, it is difficult to control the human strength in a balanced manner, and it is easy to break or strain the piston ring. Contents of the invention [0003] The object of the present invention is to overcome the shortcomings and deficiencies of the prior art, and provide a piston ring assembly device which can conveniently install the piston ring and is easy to control. [0004] The purpose of the present invention is achieved through the following technical solutions: a pist...
