Description

Technical Field

[0001] The utility model relates to the field of machining, and particularly relates to a grinding head bracket. Background Art

[0002] The fan blade is one of the core components of a wind turbine. High requirements are imposed on the materials of the fan blade. It not only needs to have a light weight, but also needs to have high strength, corrosion resistance, and fatigue resistance. At present, when manufacturing fan blades, the blade housing often uses glass fiber-reinforced resin, and the blade tip and the blade main beam use carbon fiber with higher strength. After the blade is formed, the surface needs to be polished to ensure accurate forming and smooth surface.

[0003] At present, the length of the fan blade can reach up to hundreds of meters. When grinding, even if it is placed flat on the ground, the height of the high point of the warped part from the ground can reach nearly ten meters. Therefore, it is required that the grinding head can operate stably and flexibly at this height, and the grinding head bracket needs to meet its own stiffness and mobility.

[0009] A telescopic drive assembly: including two telescopic drive elements respectively arranged at the swing ends;

[0010] A mounting bracket: connecting the movable ends of the two telescopic drive elements together.

[0011] According to the grinding head bracket of the embodiment of the utility model, the rotary drive element and the swing drive element form a two-axis movable structure. The mounting bracket is arranged on the telescopic drive element, and the grinding head is arranged on the mounting bracket, so that the grinding head has three degrees of freedom of movement in space. While moving flexibly, it also has a strong load-bearing capacity, and improves the grinding pressure of the grinding head on the surface of the fan blade during grinding.
