Description

Technical Field

[0001] The utility model relates to the technical field of parts loading and transportation, in particular to a vertical connecting rod packaging lining structure. Background Art

[0002] The connecting rod connects the piston and the crankshaft, transmits the force exerted on the piston to the crankshaft, and converts the reciprocating motion of the piston into the rotational motion of the crankshaft. The connecting rod body consists of three parts. The part connected to the piston pin is called the small end of the connecting rod; the part connected to the crankshaft is called the big end of the connecting rod, and the rod connecting the small end and the big end is called the connecting rod shaft. The small end of the connecting rod is mostly a thin-walled circular ring structure. In order to reduce the wear between the piston pin and the small end, a thin-walled bronze bushing is pressed into the hole of the small end. Drill holes or mill grooves on the small end and the bushing to allow the splashing oil foam to enter the mating surface of the lubricating bushing and the piston pin. The connecting rod shaft is a long rod, which is also subjected to large forces during work. In order to prevent it from bending and deforming, the rod shaft must have sufficient rigidity. For this reason, the connecting rod shaft of the automotive engine mostly adopts an I-shaped section. The I-shaped section can minimize the mass when the rigidity and strength are sufficient. High-strength engines have an H-shaped section. Some engines use the small end of the connecting rod to spray oil to cool the piston, and a through hole must be drilled in the longitudinal direction of the rod shaft. To avoid stress concentration, the connecting rod body and the small and large ends are connected with a large arc for smooth transition. To reduce engine vibration, the mass difference of the connecting rods of each cylinder must be limited to the minimum range. When assembling the engine in the factory, the connecting rods are generally grouped according to the mass of the large and small ends in grams, and the same group of connecting rods is used for the same engine.

[0003] Nowadays, the connecting rods are generally placed horizontally, which makes the placement of the connecting rods unstable. In addition, when multiple connecting rods are placed, the connecting rods are prone to collision, which will cause damage to the connecting rods and is inconvenient for the placement and transportation of the connecting rods.
