Abstract

The invention provides a press-fitting device for piston pins. The device comprises piston pin fixtures, a supporting disk, a guiding shaft perpendicularly arranged in the middle of the supporting disk, a sliding pipe and a driving mechanism for driving the sliding pipe to reciprocate in the axial direction of the guiding shaft; a mounting disk is arranged at one end, close to the supporting disk, of the sliding pipe; connecting rods are arranged on the mounting disk; the piston pin fixtures are parallel with the guiding shaft; each piston pin fixture comprises a connecting shaft, one piston pin and a centering press head, the mounting end of the connecting shaft is detachably connected with the connecting rod, and the connecting end of the connecting shaft is in threaded connection with a mounting shaft of the centering press head; conical guiding surfaces are arranged at press-fitting ends of the centering press heads; outer surfaces of the connecting shafts are sleeved with the piston pins; and one end of each piston pin abuts against a limiting bulge of the mounting end, and the other end of each piston pin abuts against the centering press head. With the device, the labor intensity of operators can be effectively reduced, and meanwhile, the assembly quality of the piston pins can be 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...
