The top of the tooling base has a placement slot for the interior trim panel. The interior trim panel is clamped into the placement slot by the clamping assembly mounted on the tooling base. The clamping assembly consists of a pressure plate frame 2, a telescopic electric cylinder, a first pull rod 11, a rotating shaft 9, a first push-pull plate assembly 10, a second pull rod 4, a second push-pull plate assembly 5, and a clamping end structure. The first and second pull rods are vertically arranged diagonally on the tooling base. The lower ends of the first and second pull rods are each connected to a telescopic electric cylinder embedded in the bottom of the tooling base. The cylinders are connected. The upper end of the first pull rod is connected to the lower end of the rotating shaft via a rotating structure. The upper end of the rotating shaft passes through the pressure plate frame. The first push-pull plate assembly is fixed on the rotating shaft and contacts the upper and lower surfaces of the pressure plate frame. The second push-pull plate assembly is fixed on the second pull rod and contacts the upper and lower surfaces of the pressure plate frame. A through slot is provided on the pressure plate frame relative to the placement groove. The bottom of the pressure plate frame on all sides of the through slot is connected to a clamping end structure via a connecting plate 3. The pressure plate frame can rotate around the rotating shaft. A notch is provided on the side of the pressure plate frame facing the second pull rod. A quick-locking mechanism matching the second pull rod is provided in the notch of the pressure plate frame. During operation, the quick-locking mechanism is first opened and the pressure plate frame is rotated. At this time, the interior trim panel to be processed is placed into the placement groove. Then, the pressure plate frame is reset. At this time, the quick-locking mechanism will automatically lock. The telescopic electric cylinder is activated to use the clamping end structure to complete the fixing of the interior trim panel.
