Embodiment Construction
[0036] see Figure 1 to Figure 3 , CFM56 aeroengine low-pressure turbine blade sealing tooth notch size inspection tool embodiment of the present invention, comprising:
[0037] An inspection platform 8 with a horizontal platform (see Figure 19 );
[0038] One blade outer platform fixing assembly 5 (see Figure 9 and Figure 10 ), which is: the rear of the top surface of a rectangular plate-shaped base protrudes two steps, the vertical surface of the two steps protrudes forward, and the protrusion of the lower step exceeds the upper step to match the shape of the blade sealing tooth notch, There are through holes for fixing on the base;
[0039] A calibration assembly support table 6 (see Figure 11 to Figure 14 ), which is: a regular hexahedron, with convex grooves on the right side of the top surface, grooves to avoid chamfering at the root of the convex grooves, and threaded holes on the bottom surface;
[0040] A blade root fixing assembly 3 (see Figure 7 to Figur...

A notch size tester for sealing teeth of a low pressure turbine (LPT) blade of a CFM56 aeroengine comprises a detection console with a horizontal platform, a blade external platform fixing assembly, a blade root fixing assembly, a circular end cap, a blade clamping assembly and a calibration assembly support platform. The blade external platform fixing assembly is fixed to the back portion of the left side of the detection console via a connecting piece, the calibration assembly support platform is fixed in the front portion of the left side of the detection console, the blade root fixing assembly is fixed to the back portion of the right side of the detection console, and the blade clamping assembly is fixed in the middle of the front portion of the detection console; and via arrangement, the notch shape of the sealing teeth of the blade is just positioned on two steps of the blade external platform fixing assembly when the notch size of the sealing teeth of the blade is detected, a measuring head of a dial gauge is positioned in a position that can measure a part which needs measurement when a measuring dial gauge calibration assembly is placed on the calibration assembly support platform, and a plastic clamping chuck of the blade clamping assembly abuts against the middle of the blade. The test tool can improve the test capability for heavy repair of the blade.
Description
technical field [0001] The invention relates to a CFM56 aeroengine low-pressure turbine blade sealing tooth notch size inspection tool. Background technique [0002] With the continuous maturity of V2500 series aero-engine maintenance capabilities of my country's aircraft maintenance enterprises, the maintenance volume of CFM56 series aero-engines is increasing day by day. In order to further expand maintenance capabilities and improve profitability, it is extremely urgent to expand the in-factory maintenance capabilities of the CFM56 series. For a long time, my country's aircraft maintenance companies have been very blank in overhaul inspection capabilities for CFM56 series engine LPT BLADE (low-pressure turbine blades). The inspection and repair of CFM56LPT BLADE have to be sent for repair by outsourcing. Through statistics and investigation, one of the key points of CFM56 low-pressure turbine blade overhaul capability is dimensional inspection, which includes five parts:...
