Assembly type blade finish machining checking tool and machining method thereof

The invention discloses an assembly type blade finish machining checking tool and machining method thereof, and relates to a checking tool and a processing method thereof. The invention aims to solvethe problems that an existing gauge is complex in structure, complex in machining and manufacturing and not easy to operate, instability factors are brought to the detection precision of the blade crown of the blade, and the processing quality of the whole turbine blade is influenced. The linear positioning block (2) is embedded into an opening groove (4) of a cone block (1), the linear positioning block (2) and the conical block (1) are connected through a cylindrical head screw (3). The detection tool machining method comprises the following steps of 1, machining the conical block (1); 2, machining the linear positioning block (2); and 3, assembling the detection tool. The method is used for detecting the machining precision of the blade crown. 种装配式叶片精加工检具及该检具的加工方法，它涉及种检具及该检具的加工方法。本发明为了解决现有的检具结构复杂，加工制造复杂，而且不易操作，
