Description

Technical Field

[0001] This utility model relates to the field of aero-engine blade processing technology, specifically to a clamping and fixing device for aero-engine blade processing. Background Technology

[0002] Aero-engine blades are the core components of aero-engines, hailed as the "jewels" in the "crown jewels of industry." Their primary responsibility is to convert the energy generated by fuel combustion into propulsion for the aircraft, drawing high-temperature, high-pressure gases into the combustion chamber through high-speed rotation to maintain normal engine operation. Clamping and fixing devices for aero-engine blade processing are specialized tooling equipment used for precise positioning and reliable fixation of blades during manufacturing, repair, and inspection. Their core function is to ensure the blades maintain a stable position during processing, inspection, or assembly, preventing positional deviations caused by vibration or external forces, thereby guaranteeing processing accuracy and product quality.

[0003] However, existing clamping and fixing devices for aero-engine blade processing cannot adapt to the use of blades of different specifications and conditions for fixing, and cannot be effectively adjusted in position after clamping and fixing. This makes them unsuitable for processing in different positions, reducing their processing efficiency and utilization efficiency. At the same time, they cannot be effectively adjusted in direction, making them unsuitable for processing operations in different directions. Consequently, they cannot be effectively moved, making them unsuitable for the displacement of processing equipment, reducing their adaptability and working efficiency. Therefore, we propose a clamping and fixing device for aero-engine blade processing. Utility Model Content
