Description

Crankshaft excircle surface gear ring mounting pretreatment mechanism

Technical Field

The utility model relates to a bent axle surface treatment technical field especially relates to a processing mechanism before bent axle excircle facial make-up ring gear.

Background

The crankshaft is the most important component in the engine. It takes the force from the connecting rod and converts it into torque to be output by the crankshaft and drive other accessories on the engine. A ring gear is a gear or key gear mounted at the front or middle of a crankshaft, and is typically used to drive a camshaft gear, a chain or a toothed belt, or as a timing gear in a mechanical device to provide time-scale positioning for performing related control functions.

The installation of the gear ring on the crankshaft generally requires high precision, in the prior art, the crankshaft and the gear ring are pressed and installed by a hot press, because the gear ring and the crankshaft generally adopt interference fit, in order to ensure that the gear ring can be precisely pressed and assembled with the crankshaft, before the gear ring is pressed and installed on the crankshaft, the outer circular surface of the crankshaft is required to be clean and free of impurities, the surface of the crankshaft is required to be clean, the prior art discloses more crankshaft cleaning mechanisms, for example, chinese patent CN108405449A discloses a crankshaft surface cleaning device, two ends of the crankshaft are fixed by using a clamping mechanism, bristles on a claw holding mechanism can be always in surface contact with a shaft neck when the crankshaft rotates, the claw holding mechanism can also move left and right along the shaft neck in the cleaning process, the cleaning is more comprehensive, no cleaning dead angle exists, and meanwhile, the left and right reciprocating motion of the claw holding mechanism enables the bristles on two sides of the claw mechanism to be in a reciprocating mode to be in contact with the side surface of the crankshaft, and the side of the crankshaft can also be cleaned.

Although the above patent can realize the cleaning of the whole surface of the crankshaft without dead angles, the cleaning device of the above patent can only realize the cleaning of the surface of the crankshaft and does not relate to the blow-drying operation, which can cause dust of the environment to fall onto the outer circular surface of the crankshaft, and cause the installation precision of the gear ring on the outer circular surface of the crankshaft to be affected. Meanwhile, in order to enable the gear ring to be more tightly pressed on the crankshaft, a layer of uniform glue needs to be coated on the outer circular surface before press fitting, the combination degree of the gear ring and the outer circular surface of the crankshaft is higher after press fitting through the glue, and in the prior art, a crankshaft cleaning device does not have a glue coating function generally. After the ring gear washs, need mostly carry out the rubber coating operation at bent axle disc outside through the manual work, it is inhomogeneous that this can lead to artifical rubber coating, and if adopt solitary rubber coating mechanical equipment, just need be with the bent axle clamping after the washing again fix a position to rubber coating mechanical equipment on, shift the installation at the bent axle in-process, the dust in the environment also can pollute bent axle disc outside, influence the installation accuracy of bent axle and ring gear, use jointly through belt cleaning device and rubber coating equipment simultaneously, also can cause during the outer disc pretreatment process of bent axle, because of the bent axle shifts the switching on equipment and causes the production beat to increase, machining efficiency reduces.
