Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile wheel processing, specifically to polishing device for manufacturing automobile wheel. BACKGROUND

[0002] The hub is also called wheel rim, steel ring, hub and tire bell, is the metal part of the barrel shape and center mounted on the shaft which supports the tire, and is the important part connecting the brake drum, wheel disc and half shaft. During the processing of the hub, professional equipment is needed, and the surface of the hub needs to be polished after the hub is formed. The main production process of the hub includes melting, refining, casting, flaw detection, heat treatment, machining, dynamic balance test, air tightness test and coating. The machining process includes surface polishing and grinding steps, and the outer surface of the hub is very smooth, so the outer surface of the hub needs to be ground and polished during the processing of the hub.

[0003] During the grinding and polishing process of the existing wheel, the hub needs to be fixed on the rotatable tray first, and then the electric push rod arranged above the tray is controlled to work. When the electric push rod works, the polishing wheel is controlled to move downward, and the work of the electric push rod is stopped when the polishing wheel contacts with the outer surface of the hub. Then the tray is controlled to rotate and drive the hub on the tray to rotate, and the hub is contacted with the polishing wheel during the rotation to complete the polishing work.

[0004] The existing polishing equipment can complete the grinding and polishing work of the wheel, but only the tray rotates in one direction, the polishing speed is slow and the working efficiency is low. When the existing polishing wheel contacts with the outer surface of the wheel through the electric push rod, it is not easy to control the contact area between the polishing wheel and the outer surface of the wheel. When the contact area between the polishing wheel and the outer surface of the wheel is small, the polishing wheel cannot contact with the lowest point of the outer surface of the wheel after polishing the highest point of the outer surface of the wheel due to the self-locking function of the electric push rod, which leads to uneven polishing. When the contact area between the polishing wheel and the outer surface of the wheel is large, the friction between the polishing wheel and the outer surface of the wheel is large, which easily affects the normal rotation of the tray and the wheel, and also easily causes the problem of excessive polishing of the wheel. Finally, only one polishing wheel is arranged on the existing polishing device. When the polishing wheel is a rough polishing wheel, the outer surface of the polished wheel is rough, which affects the appearance of the wheel. When the polishing wheel is a fine polishing wheel, the polishing process is slow, which reduces the service life of the polishing wheel and the working efficiency is low. INVENTION CONTENTS
