Pressing device of engine flange bearing bush

Abstract

The invention discloses a pressing device of an engine flange bearing bush. The pressing device comprises a base, and a handle taking the shape of a Chinese character Ji, wherein the two sides of the handle are respectively fixed at the two sides of the top surface of the base through first bolts; extending ends, on the bottom surface of the base, of the first bolts are respectively fixed with a short pin and a long pin; a first opening groove is formed in one end of a bracket; the other end of the bracket is respectively fixed on the top surface and the bottom surface of the base through a second bolt and a guide block; a pressing rod is L-shaped; a middle fulcrum of the pressing rod is hinged with the bracket through a first pin shaft to form a lever structure; a second opening groove is formed in one end of a pull rod for connecting with the lower end of the pressing rod at one side of the middle fulcrum of the pressing rod through a second pin shaft; and a pressing plate and a pressing block are fixed at the other end of the pull rod through third bolts. The pressing device can reduce the influence of human factors, and improves the pressing quality and efficiency.

Description

technical field [0001] The invention relates to the field of engine assembly, in particular to a press-fitting device for an engine flanging bearing bush. Background technique [0002] At present, the axial positioning of crankshafts in the domestic internal combustion engine industry generally adopts three structural positionings: flanged bearing bushes, thrust plates, and flanged tiles. When installing the flanged bearing pad, it is necessary to use a special tool to press the flanged bearing pad in the main bearing cap into place. In order to measure the axial clearance of the crankshaft after the crankshaft is transferred accurately, it is necessary to press the flanged bearing pad in place and then press the flanged bearing pad in place. The rear end surface is attached to the rear end surface of the main bearing cap. [0003] The traditional method is: employees press the bearing bush in place with ordinary bearing bush tooling. At this time, the rear end surface of t...

Problems solved by technology

[0005] The purpose of the present invention is to provide a press-fitting device for engine flanged bearing pads with a simple and reasonable structure. The press-fitting device for engine flanged bearing pads can press-fit the flanged bearing pads in place by inserting the long and short pins into the screw holes of the main bearing cap for positioning. , and then tighten the flanged bearing pad to fit the rear end surface of the main bearing cap by pulling the pull rod, which can solve the problem of manual assembly of the flanged bearing pad without pressing and fitting in place and hanging in the air, and the rear end face of the flanged bearing pad and the rear end face of the main bearing cap The problem of unqualified crankshaft axial clearance caused by non-fitting reduces the influence of human factors and improves the quality and efficiency of press-fitting
