The invention provides a quadruple guide vane measuring device, comprising a bottom plate, a large edge plate positioning block, a small edge plate positioning block, a six-point positioning mechanism and a quadruple guide vane throat dimension measuring mechanism, a large edge plate positioning block and a small edge plate positioning block. The edge plate positioning block is fixed on the bottom plate surface, and the large edge plate and the small edge plate of the quadruple guide vane are limited by the large edge plate positioning block and the small edge plate positioning block. The six-point positioning mechanism is set on the bottom plate surface. And it is located between the positioning block of the large edge plate and the positioning block of the small edge plate; the throat size measurement mechanism of the quadruple guide vane includes three sets of measuring components arranged side by side on the bottom plate, and each set of measuring components includes an arc-shaped slideway, a connecting Bolts, sliders, connecting nuts and conical feeler gauges. Both ends of the arc-shaped slideway are supported by a support block. The connecting bolts pass through the sliders and the arc-shaped slideways in turn and are connected with the connecting nuts. The conical feeler gauge is set at the Connect the ends of the bolts. The invention can simplify the measurement steps, facilitate the operation of workers, and improve the stability and precision of the measurement.
Description
technical field [0001] The invention belongs to the technical field of guide vane measurement, in particular to a quadruple guide vane measuring device. Background technique [0002] The guide vane, as the component that affects the maximum load during the use of the engine, plays the role of guiding the airflow and changing the speed, direction and pressure of the airflow. Usually, both ends are inserted into the matching ring, and the whole guide is formed by welding forming method. During the installation process, the dimensional accuracy of the large and small edge plates on both sides is relatively high. The throat area is also an important indicator that must be measured during the installation process. The throat size is the core parameter for calculating the throat area. Its size directly affects the actual working efficiency of the gas turbine and plays a decisive role in the overall performance of the gas turbine engine. The throat area is measured by measuring th...
