Problems solved by technology

[0016] In the existing processing process, it is necessary to measure the size of the first installation side and the second installation side, that is to say, it is necessary to remove the part from the production equipment and send it to the measurement department to pass the three-coordinate Measuring by measuring machine, due to the long measurement cycle and low measurement efficiency, it is very unfavorable for the batch production of parts

Abstract

The invention discloses a high-pressure turbine guide vane mounting edge measurement method. A first mounting edge of a high-pressure turbine guide vane is a mounting edge of one side of a vane-shapedvane basin; and a second mounting edge is a mounting edge of one side of a vane-shaped vane back. The method includes the following steps: step A, constructing a measurement coordinate system x-y-z,and determining feature point parameters; step B, providing a first measurement tool used for measurement of the first mounting edge; and step C, after the size of the first mounting edge measured inthe step B is qualified, providing a second measurement tool used for measurement of the second mounting edge. According to the high-pressure turbine guide vane mounting edge measurement method provided by the invention, a measurement coordinate system is set on the basis of a step surface of the high-pressure turbine guide vane, the specific measurement tools are provided according to coordinatetransformation, thus original complex measurement detection is simplified into a manner of simultaneous detection of feature points and flatness, and measurement efficiency is greatly improved on thepremise that measurement accuracy can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of aero-engine production, in particular to a method for measuring the mounting edge of a high-pressure turbine guide vane during the turbine production process of an aero-engine. Background technique [0002] Figure 1a It is a schematic diagram of the three-dimensional structure of a high-pressure turbine assembly of an aero-engine; Figure 1b for Figure 1a Schematic diagram of the structure and principle of the high-pressure turbine assembly, see Figure 1a and Figure 1b As shown, in the manufacturing process of an aero-engine, for the high-pressure turbine assembly as shown in the figure, the production process includes casting six single-piece quadruple high-pressure turbine guide vane blanks, and then for each of the high-pressure turbine guide vanes After the blank is machined on the mounting edge, profile, sealing groove, etc., the six single-piece high-pressure turbine guide blades obtained from ...
