A piston pin pressing device

Abstract

The invention provides a press-fitting device for a piston pin. The press-fitting device comprises a bottom plate, a transmission shaft, a piston pin fixing shaft, a centering pressure head, the piston pin, a drive mechanism and a support rack, wherein the support rack is arranged at one end of the bottom plate and provided with a guide sleeve; one end of the transmission shaft is connected with the drive mechanism, and the other end of the transmission shaft penetrates the central hole of the guide sleeve to be connected with the mounting end of the piston pin fixing shaft in a threaded manner; the central hole is in slide fit with the transmission shaft; the mounting end is provided with blocking protrusion; the connecting end of the piston pin fixing shaft is connected with the centering pressure head in a threaded manner; the piston pin sleeves the piston pin fixing shaft, one end of the piston pin is abutted against the blocking protrusion, and the other end of the piston pin is abutted against the centering pressure head; the press-fitting end of the centering pressure head is of a conical structure; the transmission shaft has a first position and a second position. The press-fitting device has the advantages that the labor intensity of operators can be lowered effectively, and good assembling quality of the piston pin can be achieved.

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, the operator usually uses a hammer to strike it manually to realize the assembly of the piston pin and the pin hole on the piston and the connecting rod small hole on the piston connecting rod, thereby making the operator laborious. Higher strength, which in turn makes its assembly efficiency lower. At the same time, the assembly accuracy of this method is not easy to control, which makes it easier to make the assembly quality of the piston pin poor. Summary of the invention [0003] The purpose of the present invention is to provide a piston pin pressing device to solve the problems of high labor intensity of operators and poor assembly quality of piston pins in the prior art. [0004] In order to achieve the above objective, the present invention provides the fol...
