Description

Technical Field

[0001] The invention relates to the technical field of steam turbine blade processing, in particular to a steam turbine blade processing mechanism for a power plant. Background Art

[0002] With the continuous development of turbine blade processing technology, the requirements for blade processing accuracy, efficiency and automation are increasing. However, the existing turbine blade processing equipment still has certain deficiencies in clamping, processing positioning and multi-directional operation, which affects the quality and efficiency of blade processing.

[0003] After searching, a fixture for processing the crown of an engine blade and a method for processing an engine blade were disclosed with publication number CN112091657B, and the publication date is December 10, 2021. This patent uses a "pseudo-top" structure to replace the traditional top to clamp and fix the blades, which reduces the impact of tool letting and vibration, and avoids deformation and offset problems of blades due to axial positioning, thereby improving the rigidity and detection accuracy of blade crown processing. However, this technical solution is mainly aimed at blade crown processing scenarios, and its clamping method is only applicable to specific areas (such as blade crowns or tenons), and it is difficult to achieve all-round clamping and positioning of the entire blade, especially when processing complex curved surfaces. It lacks flexibility. In addition, the fixture does not involve blade side wall support and dynamic adjustment functions, and cannot meet the need for reverse support of the blade during grinding and polishing, limiting its application in multi-process processing.

[0004] After searching, a blade air film hole processing tool with publication number CN118003118B was disclosed, and the publication date is July 23, 2024. This patent realizes the rapid clamping and precise positioning of the blade edge plate by setting a support structure, a limit structure and an elastic preload mechanism, which facilitates efficient operation during the air film hole processing process. However, this technical solution focuses on the clamping solution of the blade edge plate, and has weak processing adaptability to other parts of the blade (such as the blade body, tenon teeth, etc.), and lacks the ability to adapt to different shape changes of the blade. At the same time, the tool does not provide the function of supporting the rear wall during the blade processing process, which may cause the blade to deviate or vibrate when subjected to a large cutting force, thereby affecting the processing accuracy.

[0005] The above problems indicate that the existing steam turbine blade processing equipment still has certain deficiencies in terms of clamping flexibility, full-range positioning capability and dynamic support during the processing. In view of this, in-depth research was conducted on the above problems, resulting in this case. Summary of the invention
