Description

Technical Field

[0001] The utility model belongs to the technical field of tooling, in particular to a turbine blade measuring tooling. Background Art

[0002] The precision castings of turbine blades need to detect the wall thickness of the blades at the specified position according to the requirements of the drawings. The detection points are marked on the surface of the blades by special tooling, and then the wall thickness is detected with an ultrasonic thickness gauge. During the process, the inspector needs to hold the blade in one hand and the measuring pen in the other hand for detection. Each blade needs to be measured at multiple points and the data recorded. The measuring personnel cannot detect and record the data quickly and accurately, resulting in low detection efficiency. The most commonly used wall thickness measurement technology is: the wall thickness measurement points of the blades are marked by customized marking templates. The marking templates are designed to be contoured and are used after passing the 3D printing blue light scanning test.
