This utility model discloses a five-axis CNC cutting and trimming positioning fixture for automotive center console panels, comprising a bracket, a lower fixed mold, an upper fixed cover, and a soft fixing device. The lower fixed mold is fixed to the top of the bracket; the upper fixed cover is detachably mounted on the lower fixed mold; and the soft fixing device is disposed between the lower fixed mold and the upper fixed cover. By placing the soft fixing device between the lower fixed mold and the upper fixed cover, the soft fixing device can press against the automotive center console panel, achieving flexible positioning of the panel. This allows the fixture to automatically adapt to panels with different curvatures (R5mm~R800mm), reducing clamping deformation (controlled to ≤0.05mm), effectively improving positioning accuracy, and significantly improving the quality of the cut edges. Simultaneously, it provides better clamping stability, is less prone to vibration during high-speed cutting, and prevents trimming burrs or chipping, thus facilitating cutting and trimming.
