Aviation blade leading and trailing edge laser contourgraph

Abstract

The invention belongs to the field of mechanical automation detection and relates to an aviation blade leading and trailing edge laser contourgraph. The laser contourgraph includes a servo motion device, a sensor measurement device and a measurement platform. The sensor measurement device is fixed on the servo motion device. The servo motion device is fixed on the measurement platform. The sensormeasurement device and the servo motion device are connected with a main control computer of the measurement platform. The main control computer controls the sensor measurement device and the servo motion device to move. A display is fixed on the upper surface of the right side of a marble table. The display is connected with the main control computer. The main control computer is fixed in the control cabinet. The main control cabinet is connected with the servo motion device and the sensor measurement device separately. The main control computer controls the servo motion device and the sensormeasurement device to move. According to the invention, the laser contourgraph is low in product positioning requirements. A product only needs to place in a detection zone generally and a system canrealize automatic rectification and error analysis; the operation is simple.

Description

technical field [0001] The invention belongs to the field of mechanical automatic detection and relates to a laser profiler for the leading and trailing edges of aviation blades. Background technique [0002] Blades are the key components of aero-engines, with a large number and complex structures, which have a vital impact on the performance of aero-engines. With the continuous upgrading of my country's advanced aero-engines, the shape of the blades is becoming more and more complex, and the requirements for its accuracy are getting higher and higher, which puts forward higher requirements for the detection of the blades. At present, the traditional three-coordinate machine contact measurement occupies most of the fields of blade inspection, but due to the characteristics of contact measurement itself, the three-coordinate contact method has become more and more difficult to meet the needs of production and processing, and the detection accuracy and efficiency have become c...

AI Technical Summary

Problems solved by technology

[0004] 1. Slow speed and low efficiency. The traditional three-coordinate mechanical contact measurement blade body scanning speed can only reach 50mm / s, and when measuring the intake and exhaust edges, the measurement speed can only reach 0.5mm / s;

[0005] 2 It is prone to interference effects, and cannot measure soft materials and ultra-thin objects;

[0006] 3 There is a radius compensation error at the measuring end;
