A kind of measurement apparatus of engine core machine turbine disc mortise radial position size, the measurement apparatus mainly include
Reference block, locating piece, contiguous block, gauge and base；
Wherein, draw-in groove and positioning spigot are machined with the base；
The reference block and locating piece are connected with the draw-in groove on base by contiguous block respectively, and are fixed by screw；Institute
The endoporus and the positioning spigot for stating the engine core machine turbine disk to be measured is connected, and spacing by angular shop bolt；
The gauge is connected by tenon tooth with the tenon tooth of the engine core machine turbine disk to be measured, and the gauge is supported with the locating piece
Touch；The reference block, locating piece, gauge and engine core machine turbine disk barycenter to be measured being projected on the base is same
On bar straight line, and the straight line is located in the draw-in groove.
Further, the contiguous block is T-shaped piece, and the draw-in groove is T-slot.
Further, it is between the pin hole on the angular shop bolt and the engine core machine turbine disk to be measured, described
Coordinated using small―gap suture between positioning spigot and engine core machine turbine disk endoporus to be measured.
Operation principle：
Tongue-and-groove radial position size L is calculated by below equation：
