The utility model discloses a device for releasing the twist alarm of inner milling center frame, which is used for milling the main journal of crankshaft and the connecting rod journal. A sliding table is arranged on the left side of the center frame and connected with the guide rail horizontally arranged on the bed. A connecting rod is fixed on the sliding table. A frame is fixedly connected with the sliding table. A connecting plate is arranged on the frame. A through hole is drilled on the lower right side surface of the center frame. A second oil cylinder is arranged on the lower right side surface of the center frame. A guide hole is drilled on the end surface of the center frame close to the second oil cylinder. A traction mechanism is arranged between the two guide grooves and at the lower end of the center frame. A first oil cylinder is vertically downwardly arranged on the upper surface of the center frame above the traction mechanism. The piston rod of the first oil cylinder is directly inserted into the square hole of the center frame. When the center frame is horizontally moved, the sliding table drives the connecting rod and the connecting plate to move. The piston rod of the first oil cylinder is inserted into the connecting rod in the guide hole. The piston rod of the first oil cylinder tightly presses the connecting plate on the lower side of the square hole. Since the center frame has three points that can be affected by the traction force, the parallel traction force between the center frame and the guide rail can be effectively maintained.
