Blade Profile Analyzer Measuring Tool

Abstract

The invention provides a measuring tool for a blade profile analyzer, comprising: a measuring tool base; The top of the column is provided with a measuring tool top arm parallel to the measuring tool base, and the front end of the measuring tool top arm is provided with a first pair of standard blocks; the measuring tool front column is fixed and installed by bolts In front of the measuring tool column, the top of the front end of the measuring tool front column is provided with a second matching block, and the second matching block is located on the same plane as the first pairing block; the supporting positioning structure, The support positioning structure includes a first support arm and a second support arm, and the first support arm is fixedly installed on the upper part of the measuring tool column through bolts; the present invention has simple structure, convenient operation, and can quickly locate And the blade is fixed, the positioning accuracy is high, the time required for detection is greatly shortened, and the detection conditions are provided for batch detection of blades.

Description

technical field [0001] The invention relates to the technical field of testing tooling, in particular to a measuring tool for a blade profile analyzer. Background technique [0002] The turbine guide is an important part located in the aero-engine, its function is to change the flow direction of the gas and push the blades to rotate. The working environment of the turbine guider is harsh. It not only has to bear the large thermal stress caused by the high-temperature gas flow and uneven heating of various parts, but also bears the aerodynamic force generated when the gas passes through and the vibration load caused by the pulsation of the airflow. . The inner and outer rings of the turbine guider are equidistantly distributed along the circumferential direction with guider blades, which are used to change the flow direction of the gas, so the quality of the guider blades is particularly important. For the quality inspection of the guider blades One is the detection of the ...

Problems solved by technology

The inner and outer rings of the turbine guider are equidistantly distributed along the circumferential direction with guider blades, which are used to change the flow direction of the gas, so the quality of the guider blades is particularly important. For the quality inspection of the guider blades One is the detection of the blade shape of the guider blade. The existing technology usually uses coordinate detection for the detection of the blade shape of the guider blade. This detection method uses the blade shape analyzer to model the coordinates of the blade, and then compares the detection model with the ideal Model comparison, but this detection method does not have a dedicated measuring tool, so it takes a long time to detect during the detection process, and the blade cannot move at all during the detection, otherwise the detection accuracy will be affected, and it cannot provide detection for batch detection. condition
