Abstract

The invention discloses an assembly device for a diesel engine piston pin. The assembly device comprises a piston pin guide assembly, a piston sleeve assembly, a piston pin supporting block and a piston pin pressing assembly which are positioned at corresponding positions of a slot on a bottom plate, wherein a piston pin is placed on the piston pin supporting block; the piston sleeve assembly comprises a piston sleeve, and notches are formed at two sides of the piston sleeve; the piston pin guide assembly comprises a positioning core shaft; the piston pin pressing assembly comprises a push rod; and the push rod is coaxial with the positioning core shaft. When being assembled, the piston pin is penetrated into the notch at the other side of the piston sleeve, a pin hole in a piston and a hole at a small end of a connecting rod in sequence under the positioning action of the positioning core shaft and the pressure action of the push rod, so that the piston pin is pressed into the pin hole in the piston and the hole at the small end of the connecting rod and are in close fit with the pin hole in the piston and the hole at the small end of the connecting rod respectively. Through the assembly device, assemblies can be prevented from being damaged, cylinder holes can be prevented from being pulled, and production efficiency can be greatly increased.

Description

technical field [0001] The invention relates to the field of diesel engines, in particular to an assembly device and method for a piston pin of a diesel engine. Background technique [0002] The piston connecting rod group is an important part in the diesel engine, and its assembly quality has a direct impact on the sealing and service life of the cylinder. Most of the assembly piston pins in the prior art can only be manually tapped with a copper hammer or assembled with a press machine without guidance, which often causes crushing of the piston pin and piston, and in severe cases will strain the cylinder bore, resulting in " "Cylinder" failure, and low production efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the above-mentioned prior art, realize the smooth assembly of the piston pin into the pin hole on the piston and the small head hole of the connecting rod through guiding positioning and coaxial pus...
