Description
Technical Field
[0001] This utility model relates to the field of wind turbine blade processing technology, specifically to a tail edge saw tooth processing equipment for wind turbine blade processing. Background Technology
[0002] In the machining process of wind turbine blades, the machining accuracy of the trailing edge serration structure directly affects the aerodynamic performance and operational stability of the blades. Therefore, specialized equipment is required to achieve efficient and precise machining. Currently, existing trailing edge serration machining equipment has many problems in practical applications: Regarding debris collection, glass fiber, resin and other debris generated during processing are easily scattered, which not only pollutes the working environment, but may also be inhaled by operators and harm their health. At the same time, debris accumulation in the processing area will affect the tool life and processing accuracy. Existing equipment mostly uses simple ventilation devices, which have a limited collection range and low efficiency. In terms of clamping, the wind turbine blades have complex curved surfaces and large size differences. The existing clamping mechanisms lack flexibility in adjusting the support points and clamping force, making it difficult to accurately match the shape contours of different blades. This causes the blades to wobble slightly during processing, affecting the dimensional accuracy of the saw teeth. Furthermore, the clamping process requires multiple manual calibrations, which is cumbersome and time-consuming, severely restricting the production pace. In terms of automated grinding, existing equipment mostly relies on manual assistance to complete the grinding process, which is not only labor-intensive, but also makes it difficult to ensure the consistency of the saw teeth edges. Especially in mass production, the product qualification rate fluctuates greatly, which cannot meet the needs of efficient and standardized production.
[0003] With the rapid development of the wind power industry, higher demands are being placed on the processing quality and production efficiency of wind turbine blades. Existing equipment can no longer meet actual production needs in terms of the comprehensiveness of debris collection, the adaptability and stability of clamping, and the automation and precision of grinding. Therefore, developing a trailing edge serration processing device that can effectively collect debris, stably clamp blades of different specifications, and achieve automatic and precise grinding has become an urgent technical problem to be solved in the industry. In view of this, we propose a trailing edge serration processing device for wind turbine blade processing. Utility Model Content
