Description

{A connecting rod processing}

The present invention relates to a machining method for operating a connecting rod, and more particularly, to a jig suitable for each workpiece can be rapidly and accurately replaced with a machining apparatus when various connecting rods of different sizes are machined, The present invention relates to a connecting rod processing method which can be applied economically to a small-scale processing site because it can smoothly perform a small number of small-lot processing.

Generally, when the components of an automobile engine are roughly divided, a plurality of cylinders are integrally formed as a part constituting the main body of the engine, and a water jacket in which cooling water flows and a cylinder block And a cylinder head disposed at the upper portion of the cylinder block and forming a combustion chamber together with the piston. The cylinder head is provided with various valve mechanisms, spark plugs, injection valves, and the like, and a crankcase provided with a crankshaft.

A cylinder formed integrally with the cylinder block is provided with a piston which moves up and down along the wall surface of the cylinder by the rotational force of the crankshaft transmitted through the connecting rod. In the combustion chamber provided by the cylinder head and the head portion of the piston, The air introduced into the intake port through the manifold is sucked.

As described above, the air sucked through the intake system mixes with the fuel injected from the injection valve to form a mixer, and the mixer compressed by the piston moving up and down along the cylinder wall by the connecting rod connected to the crankshaft By ignition by the spark plug, the crankshaft is rotated by the explosive force generated at this time to obtain power.

The connecting rod is connected to the crankshaft and is used as a medium for vertically reciprocating the piston. Bearing is provided on the crankshaft, and the connecting rod and the connecting cap are mounted on the crankshaft as bolt fastening means .

Accordingly, in order to connect the connecting cap to the connecting rod with a bolt, a flange portion facing each other is formed on the connecting rod and the connecting cap, and the bolt hole is machined through the flange portion.

And the connecting rod and the connecting cap have an assembling surface which is in contact through the flange portion.

Therefore, the assembling surfaces of the connecting rod and the connecting cap are given a tolerance with respect to each other, and the crankshaft is precisely assembled.

As described above, the connecting rod may be a separate type connecting rod that is manufactured by separating a rod portion and a cap portion from each other in a material state according to a manufacturing method thereof, And an integral type connecting rod which is manufactured by separating the rod portion and the cap portion and then tightening them.

Then, a force is applied to a stressed portion by using a hydraulic mandrel (MANDREL) It is separated into rod and cap.

The connecting rod manufacturing method using the cracking method is separated into a rod and a cap by using a hydraulic mandrel MANDREL so that particles separated from the large end surface Inevitably, this causes air bubbles to be generated at the fracture site, and vibrations are applied to the connecting rod to remove the sludge particles attached to the material.
