Coreless marine propeller static balance instrument and static balance detection method therefor

Abstract

The invention discloses a coreless marine propeller static balance instrument and a static balance detection method therefor. A suspending weighing mechanism is fixedly connected to the bottom of a three-claw supporting part which is located exactly above. The top of the three-claw supporting part is fixedly connected to a centering detection mechanism, and the exterior of the three-claw supporting part is sleeved by a centering adjustment mechanism. The three-claw supporting part vertically passes through the centering adjustment mechanism, and the bottom of the centering adjustment mechanism is supported on the suspending weighing mechanism. The centering detection mechanism is used for preliminarily guiding a propeller for placing, and the centering adjustment mechanism adjusts the position of the center of the propeller according to the feedback data of the centering detection mechanism. The suspending weighing mechanism is used for the suspending of the propeller, detecting the mass deviation and weighing the weight of the propeller. A visual imaging device and a laser triangular range-finding instrument are employed for collecting the offset of the center of the propeller and the offset of a calibration center. A servo motor is used for controlling a guide rail to move the center of the propeller, thereby achieving the centering, achieving the coreless high-precision centering and improving the centering error and static balance detection precision.

Description

A coreless marine propeller static balance instrument and its static balance detection method technical field The invention relates to a static balance detection technology, which is suitable for static balance detection of large-scale marine propellers. Background technique The size of propellers used in large-scale ships is getting bigger and bigger, and the speed is getting faster and faster at the same time, so the requirements for the unbalanced quality of the propellers are getting higher and higher. The current propeller static balance detection mainly includes the balance shaft rolling method and the swing method. The centering methods of these two detection methods are to center the mandrel, lift the propeller, adjust it to the horizontal buckle and put it on the mandrel for centering. , and then use the cone cap on the upper end to squeeze and lock, so that the propeller and the mandrel form a whole and then inspect it. After the inspection is completed, remove t...
