Technical Field

[0001] This utility model relates to the field of front suspension bracket processing technology, and in particular to a front suspension bracket grinding platform. Background Technology

[0002] The grinding platform of the front suspension bracket refers to a special tooling or equipment system used to support, position and fix the bracket workpiece, and cooperate with the grinding machine to complete high-precision grinding.

Insufficient precision: Thin-walled parts are easily deformed, and the uneven distribution of clamping force in traditional fixtures leads to excessive flatness deviations after machining (usually >0.02mm); 3. Insufficient precision: Thin-walled parts are easily deformed, and the uneven distribution of clamping force in traditional fixtures leads to excessive flatness deviations after machining (usually >0.02mm).

This effectively reduces the time spent replacing the front suspension bracket positioning device. Multiple sets of multi-modal adsorption units can be configured according to actual needs, enabling stable positioning of front suspension brackets of different shapes, thereby significantly improving the applicability of the grinding platform.
