Technical Field

The invention relates to the field of machining, in particular to an automobile brake disc polishing device.

Background

The brake disc is simply a round disc, when a vehicle runs, the brake disc also rotates, the brake calipers clamp the brake disc to generate braking force, when the vehicle is stepped on, the brake disc is clamped to play a role in reducing speed or stopping, the brake disc has good braking effect and is easier to maintain than a drum brake, the prior brakes are provided with a disc brake and a drum brake and also provided with an air brake, the old vehicles are mostly front-disc and rear-drum brakes, the prior vehicles are mostly disc brakes in front and at the back, because the disc brake has better heat dissipation than the drum brake, the heat fading is not easy to generate in a high-speed braking state, the high-speed braking effect is good, but when the low-speed cold brake is performed, the braking effect is not as good as that of the drum brake.

When the brake disc is machined, the brake disc needs to be polished, the conventional brake disc polishing device, particularly the fixing and clamping device can only fix the brake disc with one size and model, the application range is small, and therefore the conventional polishing device needs to be improved.
