Abstract

The invention discloses a device for detecting the size of an engine blade, and the device comprises a first detection body for detecting the size of the blade, and a stopper piece. The first detection body comprises a first detection cavity, and the first detection cavity comprises a first detection edge. The length of the first detection edge is the maximum theoretical value of a first to-be-detected edge of the blade, and the thickness of the stopper piece is the minimum tolerance value of the first to-be-detected edge. According to the invention, the blade is placed in the first detection cavity of the first detection body. If the blade can be put in the first detection cavity, it indicates that the length of the first to-be-detected edge meets the requirements, and the stopper piece is inserted into the first detection cavity, and the device carries out the detection of the minimum size of the first to-be-detected edge. Obviously, the device achieves the detection of the size of the blade of an engine through the cooperation of the first detection cavity and the stopper piece, solves problems that engine blade detection is high in cost and is long in detection time. Moreover, the device is simple in structure, is convenient to detect, shortens the detection time, and shortens the generation period of the blade.

Description

technical field [0001] The invention relates to the technical field of engine detection, and more specifically relates to an engine blade size detection device. Background technique [0002] With the growth of engine demand, the demand for various blades in the engine has also increased significantly. The size and shape of the blades are complex and irregular, and the size requirements of each piece are relatively high, and many blade sizes are composed of linear dimensions and angles. Conventional measuring tools such as calipers and angle rulers cannot complete the measurement and inspection of blade sizes. Currently, if figure 1 As shown, the lengths of A and B of the blade are the elements to be measured, and the angle C is the included angle after the horizontal projection of the two sides. A, B, and C are the measurement elements of the engine blade to be detected. The measurement of the blade size adopts the method of measuring with measuring equipment such as three...
