A piston pin pressing device

Abstract

The invention provides a piston pin press fitting device which comprises a shell, a guide transmission shaft, a telescopic power piece and a connection plate, wherein a mounting open slot is formed in one side of the shell; a U-shaped containing open slot is formed in the lower portion of the mounting open slot; the opening direction of the mounting open slot is the same as the opening direction of the containing open slot; the telescopic power piece is arranged on the top wall of the mounting open slot; the telescopic end of the telescopic power piece is connected with the first end of the connection plate; the guide transmission shaft penetrates through a via hole in the top wall and is connected with the second end of the connection plate; an alignment pressing head is arranged on one side, which is far away from the top wall, of the guide transmission shaft; the press fitting end of the alignment pressing head is of a conical structure; a press fitting hole through which the press fitting end penetrates is formed in the bottom wall of the mounting opening slot; a press fitting tray is arranged on the bottom surface of the containing open slot; and the guide transmission shaft has a position to be subjected to press fitting and a press fitting completed position. According to the piston pin press fitting device disclosed by the invention, the assembling efficiency can be greatly improved, and the assembling quality of a piston pin is relatively high.

Description

technical field [0001] The invention relates to the technical field of engine assembly, in particular to a piston pin press-fitting device. Background technique [0002] In the prior art, when assembling the piston pin, usually the operator manually hits it with a hammer to realize the assembly of the piston pin with the pin hole on the piston and the small end hole of the connecting rod on the piston connecting rod, thus making the labor of the operator The strength is relatively high, which in turn makes its assembly efficiency low. At the same time, the assembly accuracy of this method is not easy to control, so that the assembly quality of the piston pin is relatively poor. Contents of the invention [0003] The purpose of the present invention is to provide a piston pin press-fitting device to solve the problems in the prior art that the labor intensity of the operator is relatively high and the assembly quality of the piston pin is poor. [0004] To achieve the abo...
