Abstract

The invention discloses a laser measuring device for an adjustable paddle blade. The laser measuring device comprises a base, a rotary table, a laser displacement sensor, a transverse moving mechanism and a longitudinal moving mechanism, wherein the base is used for supporting other parts of the measuring device; the rotary table is arranged on the base and used for placing and rotating the adjustable paddle blade to be measured; the transverse moving mechanism is used for adjusting the position, corresponding to a measuring point on the adjustable paddle blade, of the laser displacement sensor in the horizontal direction; the longitudinal moving mechanism is used for adjusting the position, corresponding to the measuring point on the adjustable paddle blade, of the laser displacement sensor in the vertical direction; and the laser displacement sensor is used for collecting the distance between the measuring point on the adjustable paddle blade and the laser displacement sensor. The invention provides a laser measuring system and a laser measuring method for the adjustable paddle blade. With the principle of laser triangulation, the space coordinates of the measuring point are obtained, full automatic measurement of the adjustable paddle blade is realized, and the measurement precision and efficiency are effectively improved.

Description

Technical field [0001] The invention belongs to the field of advanced measurement technology, and specifically relates to a laser measurement device, system and method for a controllable propeller blade. Background technique [0002] In the current aviation, navigation and automotive fields, free-form surface parts have more and more applications, which puts forward higher requirements for the measurement of free-form surface parts. Measurement accuracy and efficiency directly affect the accuracy and effectiveness. [0003] Large-scale marine propellers are typical complex curved workpieces. The shape accuracy of their blades affects the performance of the propeller to a large extent. The blades of the controllable pitch propellers are a new form of blades on ships. The use of controllable pitch propellers will become more and more widespread. The blades of controllable pitch propellers are not fixed on the hub and can rotate around an axis perpendicular to the propeller shaft. T...
