Embodiment Construction

[0036] The present invention will be further described below in conjunction with accompanying drawing.

[0037] like figure 1 , figure 2 As shown, the gas turbine blade precision rapid detection device provided by the present invention includes a workbench 1 and a blade positioning device. The blade positioning device is fixed on the middle part of the table surface of the workbench 1. The positioning baffle 4 is composed of a baffle 4, and the positioning baffle 4 is vertically fixed on one end of the tenon positioning element 3. The tenon positioning element 3 is provided with a slot 31 for positioning the blade, and the positioning pin 2 is vertically fixed on the inner side of the positioning baffle 4 and extends into the Put it in the slot. Profile measuring devices are arranged symmetrically on both sides of the blade positioning device, and the profile measuring device is fixed above the workbench 1 through a column 16 .

Abstract

The invention discloses a rapid detecting device and a detecting method of the precision of blades of a gas turbine. A detected blade is positioned by a blade positioning device; and profile measuring devices are symmetrically arranged at two sides of the blade positioning device and used for acquiring profile data of the section of the blade. By adopting the rapid detecting device and the detecting method, the workload for acquiring blade conic data is greatly reduced; influence from personal factors is little and the data acquiring speed is high; contact type measurement by a measuring pen is adopted with high measurement precision; the arithmetic of the profile data of a discrete section is simple and mature, is high in precision and is easy for subsequent error analysis calculation; the height and the quantity of the profile data is selective and adjustable and has high flexibility; the mechanical structure is simple, the cost is relative low and the measurement precision is ensured.

Description

technical field [0001] The invention relates to precision testing equipment and a testing method based on the testing equipment, more precisely, a fast testing device and a testing method related to the precision of gas turbine blades after machining. Background technique [0002] A gas turbine is a rotary impeller power mechanical device that converts the heat energy generated by the combustion of gas or liquid fuel (such as natural gas, fuel oil) into mechanical work. It is widely used in energy, aviation, transportation, national defense and other fields. And the key major equipment for the development of aviation industry. High-temperature turbine blades are located in the part of the gas turbine with the highest temperature (above 1400°C), the most complex stress, and the harshest environment. Its value accounts for nearly 50% of the total product and is a key component of the gas turbine. The machining accuracy of the blade has become one of the important factors affe...
