The invention discloses a device for detecting deflection of a turbine disk tongue-and-groove and a method. The device comprises a positioning part, a pressing part, and a measuring part. The positioning part is matched with a toothed surface of the turbine disk tongue-and-groove by a toothed block, and is positioned by a plate and a front end surface of the turbine disk. The toothed block is fixed in the turbine disk tongue-and-groove by the pressing part. The measuring part comprises a dial indicator stand that is rotatable relative to the toothed block, and the other end of the dial indicator stand is sleeved on a projecting shaft of the toothed block. The device for detecting deflection of a turbine disk tongue-and-groove and the method solve the problem that the deflection of the turbine disk tongue-and-groove relative to the turbine disk is difficult to measure. The deviation of the deflection of the turbine disk tongue-and-groove relative to the turbine disk is conveniently andquickly measured through a final result, and the actual operation is convenient and fast and low in cost.
Description
technical field [0001] The invention relates to a turbine disk tenon and groove detection technology, in particular to a turbine disk tenon and groove deflection detection device and method. Background technique [0002] The turbine is an important part of the aero-engine, and the processing quality of the turbine is directly related to the performance index of the aero-engine. In the deflection detection of the tenon and groove of the turbine disk relative to the turbine disk, it is difficult to accurately measure the position deviation using conventional methods. The three-coordinate inspection is generally used in the development stage of the turbine disk. The three-coordinate inspection in the mass production stage takes a lot of time and cannot be measured. To meet the production schedule requirements, it is necessary to develop a fast and accurate detection tool. [0003] At present, no detection tool that can meet the above rapid detection requirements has been repor...
