The utility model belongs to the technical field of aluminum
pipe machining, and particularly relates to an aluminum
pipe straightening device which comprises a cabinet, a bottom shell fixedly connected to the upper side of the cabinet, a top shell fixedly connected to the bottom shell, a three-jaw chuck rotatably connected in the top shell and the bottom shell, an aluminum
pipe fixedly clamped by the three-jaw chuck, a first air cylinder fixedly connected to one side of the cabinet and the top shell, and a second air cylinder fixedly connected to the other side of the cabinet and the top shell. The extension end of the first air cylinder extends into the aluminum pipe and is fixedly connected with a ball cup, one end of the ball cup is fixedly connected with a ball, the outer surface of the ball is provided with a wear-resistant and compression-resistant
coating, the ball is tightly attached to the inner wall of the aluminum pipe and slides relative to the inner wall of the aluminum pipe, a straightening component is arranged on the
machine cabinet, and multiple sets of detection components are arranged on the
machine cabinet and located on the two sides of the aluminum pipe. According to the aluminum pipe straightening device, the aluminum pipe is straightened through the straightening component, meanwhile, the aluminum pipe is synchronously supported through the ball head in the aluminum pipe, so that the aluminum pipe is prevented from being extruded and deformed during straightening, the straightening quality is improved, the straightening effect can be synchronously detected through the detection component in the straightening process, and the straightening work efficiency is improved.
