Description

Technical Field

[0002] The brake disc is a very important component in the braking system. The brake disc is used for braking. The brake pad includes a mounting surface connected to the wheel axle of the car and a brake surface that is in detachable contact with the brake caliper. There are bolt holes on the mounting surface for fixing the brake disc. Some brake discs also have cooling air ducts between the brake surfaces. The braking force of the brake disc comes from the brake caliper. A good brake disc has stable braking, no noise, and no shaking. After long-term use, the mounting surfaces on both sides of the brake disc are easily affected by the external environment and rusted, causing the mounting surface to become thinner and the strength to decrease, which in turn affects the braking performance of the brake disc. Therefore, it is often necessary to spray anti-corrosion on the mounting surface of the brake disc.

[0003] However, when spraying the mounting surface of the brake disc, the existing brake disc spraying equipment often causes the nozzle to splash excess paint onto the braking surface of the brake disc, resulting in loose contact between the brake caliper and the braking surface during braking, leading to poor braking effect of the brake disc. The present solution solves the technical problem of poor spraying effect of the existing brake disc spraying equipment. Utility Model Content
