Abstract

The invention discloses a fixing device for a detection lever of an engine borescope, thereby effectively solveing problems existing in existing aero-engine borescope detection. The fixing device hasadvantages of small tool number and simple structure; and the labor cost in the detection process can be effective saved and the detection efficiency can be improved. A first threaded sleeve and a second threaded sleeve rotate to clamp each other; a first clamping plate and a second clamping plate clamp a detection lever; and three groups of jacking locks adjust the position of the detection leverslightly. While the fixation of the detection lever is ensured, the operation difficulty is reduced. With the clamp, the engine detection efficiency can be improved, the labor cost in the detection process can be lowered, and the economic benefit can be increased.

Description

technical field [0001] The invention belongs to the technical field of engine borescope, and in particular relates to a fixing device for a probe rod of an engine borescope. Background technique [0002] With the development of aviation technology, the internal structure of the engine has become more and more complex and precise. In order to ensure safe flight, the non-destructive testing technology of the engine is becoming more and more important. At present, in the in-situ non-destructive testing of engines assisted by a borescope, the control of the probe rod of the borescope is fixed manually. Due to the instability of the manual hand-holding method, the position of the borescope probe is inconsistent during the detection process, which affects the detection results of the blade and reduces the safety factor of the engine. At the same time, the hand-held fixing method of the hole probe probe increases the labor cost in the detection process and reduces the detection ef...
