Assembling tool and assembling method for large-size split type composite propeller

Abstract

The invention relates to a large-size split type composite material propeller assembling tool. The large-size split type composite material propeller assembling tool comprises a main body platform, a bottom supporting disc, a propeller blade positioning adjusting ring, a blade supporting adjusting movable block and a blade root supporting adjusting movable block. An operation reserved round hole with the aperture not smaller than the outer diameter of a propeller hub is formed in the middle of the body platform. The diameter of the bottom supporting disc is not smaller than the aperture of the operation reserved round hole. The outer ring diameter of the blade positioning adjusting ring is consistent with the outer diameter of the propeller hub, and the blade positioning adjusting ring is located in the operation reserved round hole and arranged on the bottom supporting disc. The blade supporting and adjusting movable block and the blade root supporting and adjusting movable block are arranged on the main body platform and are respectively used for supporting the blade and the blade root of the paddle; the blade supporting and adjusting movable block and the upper surface are blade contact surfaces, and a height adjusting device is arranged on the blade supporting and adjusting movable block; the upper surface of the blade root supporting adjusting movable block is a blade contact surface, and the side face is provided with a jacking device. Through linkage adjustment of the blade supporting and adjusting movable block, the blade root supporting and adjusting movable block and the blade positioning and adjusting ring, the assembly precision is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of composite material propellers, and in particular relates to a large-size split type composite material propeller blade, a propeller hub assembly tool and a specific assembly method. Background technique [0002] At present, conventional metal propellers on the market are manufactured by integral molding to ensure the overall quality and performance. For large-size spirals, the overall manufacturing difficulty is very large. Due to the heavy weight of the metal blade, its rotational mass inertia is very large. If the metal hub and the metal blade are separately manufactured and then assembled, there will be a greater technical risk in the reliability of the connection after assembly. [0003] With the rapid development of the propeller industry, it is difficult for metal propellers to meet higher requirements for weight reduction, propulsion efficiency and vibration and noise reduction. Composite propell...
