Description

Technical Field

[0001] This utility model belongs to the field of blade processing technology, and more specifically, it relates to a drilling positioning device for blade processing. Background Technology

[0002] Currently, the importance and challenges of turbine blade machining: Turbine blades are key components of turbines, and their quality and precision directly affect turbine performance. Drilling is a crucial machining process in blade manufacturing; for example, precise drilling is required to install cooling channels or other components on the blades. Due to the complex shape of turbine blades, which typically have curved surfaces and thin walls, traditional drilling positioning devices are insufficient to meet their high-precision machining requirements.

[0003] Limitations of existing borehole positioning devices:

[0004] Ordinary drilling positioning devices can only perform simple fixed positioning and lack the ability to move freely in the XY axis direction. When machining turbine blades, the drilling positions required for different parts of the blade vary greatly, especially in the blade body. Such inflexible positioning devices cannot quickly and accurately adjust to the appropriate drilling position.

[0005] During the manufacturing process of steam turbine blades, drilling operations may be required from different angles, but many existing positioning devices lack rotation and oscillation adjustment functions. For example, due to space constraints or manufacturing process requirements, certain parts of the blade may require the drilling device to be rotated at a certain angle or oscillated to a specific posture for accurate drilling. Existing devices cannot adequately meet these needs, have low flexibility, and require manual disassembly and adjustment, making the operation very cumbersome. Utility Model Content
