Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of brake drum production and processing, and particularly relates to a brake drum turnover device. BACKGROUND

[0002] The brake drum is part of a drum brake system. When braking, the piston exerts pressure on the two pairs of half-moon-shaped brake shoes, causing them to adhere to the inner wall of the drum chamber, thereby generating friction to stop the rotation of the wheels. The basic shape of the brake drum is drum-shaped. During the processing of the brake drum, different processes require different processing surfaces of the brake drum, and the brake drum needs to be turned over. The brake drum needs to be turned over multiple times from the initial processing to the finished product.

When the clamping force of the first and second clamping seats is small, it is easy to cause the clamping to be loose, affecting the stability and safety of the brake drum during the turning process.
