Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing equipment, in particular to an aluminum alloy wheel hub drilling device. Background Art

[0002] The wheel hub is a cylindrical metal part with the inner contour of the tire supporting the tire, and the center is mounted on the shaft. It is also called a wheel rim, steel rim, wheel, or tire bell. Wheel hubs are divided into many types according to diameter, width, molding method, and material. In the past, the most common wheel hub bearings for cars were single-row tapered roller or ball bearings used in pairs. With the development of technology, car hub units have been widely used in cars. The scope and amount of use of wheel hub bearing units are increasing day by day, and have developed to the third generation: the first generation is composed of double-row angular contact bearings. The second generation has a flange on the outer raceway for fixing the bearing, which can simply put the bearing on the wheel axle and fix it with nuts. This makes the maintenance of the car easier. The third generation of wheel hub bearing units uses a bearing unit and an anti-lock brake system. The wheel hub unit is designed with an inner flange and an outer flange. The inner flange is fixed to the drive shaft with bolts, and the outer flange installs the entire bearing together.

[0003] According to the characteristics and requirements of different models, the wheel surface treatment process will also adopt different methods, which can be roughly divided into two types: baking paint and electroplating. The appearance of the wheels of ordinary models is less considered, and good heat dissipation is a basic requirement. The process basically adopts baking paint, that is, spraying first and then electric baking. The cost is relatively economical and the color is beautiful and lasts for a long time. Even if the vehicle is scrapped, the color of the wheel remains unchanged. The surface treatment process of many Volkswagen models is baking paint. Some fashionable and dynamic colored wheels also use baking paint technology. This type of wheel is moderately priced and has a full range of specifications.

[0004] Electroplated wheels are divided into silver electroplating, water electroplating and pure electroplating. Although silver electroplating and water electroplating wheels have bright and vivid colors, they only last for a short time, so they are relatively cheap and are favored by many young people who pursue novelty. Pure electroplating wheels have a long-lasting color and are of high quality and high price. Mid- and high-end cars mostly use pure electroplated wheels.

[0005] The center of the wheel hub needs to be drilled, basically five holes. The existing wheel hub drilling process is to drill the holes first and then grind them uniformly after the drilling is completed. The processing time is long and the efficiency is not high. During mass production, the drill bit and the grinding head work continuously and maintain high temperature, which is easy to be damaged and the cost loss is large. In addition, a large amount of powdery debris will be generated during grinding, which is easy to scatter around or float into the air, affecting the working environment. If inhaled by workers, it will also affect the workers' health. Summary of the invention
