Blade positioning clamping device used for blade type frame measuring tool

Abstract

The invention discloses a blade positioning clamping device used for a blade type frame measuring tool in the technical field of blade positioning clamping. The blade positioning clamping device comprises a base plate, a locking device is movably connected with the left end of the base plate through a rotary shaft, and a supporting pin is installed at the top of the base plate. A supporting rod is arranged on the right side of the supporting pin, a pressing rod is movably connected with the top of the supporting rod through a pin shaft, and the bottom of the right side of the pressing rod is connected with the output end of a hydraulic cylinder. A movable pressing plate and a fixed pressing plate are transversely arranged on an inner cavity of the locking device, the movable pressing plate is located at the top of the fixed pressing plate, and an adjusting screw is rotatably connected with the top of the movable pressing plate. According to the blade positioning clamping device used for the blade type frame measuring tool, through design of the leverage principle, the root of a blade is pressed through vertically-downward force generated on the rearward face of the root of the blade; and due to the fact that the blade tip of the blade is fine, the blade is clamped through a manually-locking mode, so that clamping force is more easily controlled, and the blade is prevented from being damaged in the clamping process.

Description

technical field [0001] The invention relates to the technical field of blade positioning and clamping, in particular to a blade positioning and clamping device for a blade-type frame measuring tool. Background technique [0002] Blades are the key components of wind turbines to effectively capture wind energy. Under the condition of a certain generator power, how to improve power generation efficiency and capture greater wind energy has always been the goal of wind power generation. The improvement of wind capture capacity is related to the shape of blades , length and area are closely related, and the size of the blade mainly depends on the material of the blade. The lighter the material of the blade, the higher its strength and stiffness, and the stronger the load capacity of the blade. With the rapid increase of the capacity of the current large-scale wind turbines, the length of the blades also increases. The increase in the length of the blades will inevitably increase ...
