Description

TECHNICAL FIELD [0001] The present invention relates to a car bearing hub coating apparatus,

The present invention relates to an automotive bearing hub coating apparatus, and more particularly, to an automotive bearing hub coating apparatus capable of coating a bearing hub on which a wheel of an automobile is mounted.

Nowadays, automobile products are changing in various ways according to the needs of consumers. These changes can be largely divided into functional and aesthetic parts. Here, the functional part is for enhancing the functionality such as stability, acceleration and convenience of the car, and the aesthetic part is for enhancing the beauty such as beauty and sophistication.

However, these days the boundaries between functional and aesthetic parts are becoming blurred in the production of automotive products. In other words, consumers are demanding both functional and aesthetic aspects, and automotive products are evolving to meet these demands.

And, the process that is at the boundary between the functional part and the aesthetic part is the foot coating process. The automotive coating process raises the aesthetics of the car, making it look cleaner, and at the same time it is also possible to enhance the functional parts because it prevents corrosion on the surface of the car through the coating process.

These automotive coating processes can be divided into glass coating, undercoating and exterior coating.

In the case of external coating, since the part to be coated is very wide, it is possible to perform mechanical coating by coating apparatus. However, in contrast, since the portion to be coated is too wide, coating on the fine portion may not be properly performed, and a finish coating process must be manually performed in this case.

In the case of glass coating and undercoating, since the portion to be coated is not a coating for the whole part of the automobile, mechanical coating by the coating apparatus is almost impossible, and it is generally done by hand from the beginning to the end.

On the other hand, a single automobile consists of tens of thousands of parts combined. And, among these parts, there is a bearing hub.

The bearing hub is a structure for connecting a wheel of an automobile to an automobile shaft. In particular, the bearing hub is fastened to a brake disc which plays an important role in stopping the vehicle.

For reference, in order for the moving vehicle to stop, the brake disc and the brake pads come into contact with each other, and the friction disc is stopped by the friction generated by the contact. The stop of the brake disc means a stop of the automobile.

On the other hand, automobiles are subjected to various kinds of wind waves during stopping and running, which causes corrosion. As described above, automobiles can be coated to prevent corrosion. However, the bearing hub and the brake disc are typical automobile parts that are not coated.

In the case of the brake disc, the coating process is not performed because the brake disc is frictionally engaged with the brake pad. And, as is the case with other internal parts of automobiles, the bearing hub also generally does not consider the coating process for reasons such as tolerances. In addition, even if a coating process is desired, there is no mechanical device for this, so it is a reality that a coating process must be performed manually.

On the other hand, when the running distance or the modeling of the vehicle is long, the brake disk is aged. And thus the brake disc must be replaced.

However, as explained above, automobiles can cause corrosion due to various reasons. That is, corrosion may occur between the bearing hub and the brake disc. In this case, the bearing hub and the brake disk are strongly and undesirably strongly coupled by corrosion, and it is almost impossible to disadvantage the bearing hub and the brake disk in order to replace the brake disk.
