In order to develop a higher-end ship, higher requirements are put on the processing and manufacturing technology of the propeller.
The detection and polishing of the static balance of the propeller are a key process in the processing and manufacturing process of the propeller; propellers which do not meet the requirements of static balance can generate large centrifugal force, vibration and the like during operation, and finally can affect the working performance and reduce the service life. At present, the main modes of detecting and polishing static balance of a large propeller in the industry are as follows: the magnitude and the direction of the unbalance are detected by a vertical static balancing instrument, and then the unbalance is ground by a manual angle grinder. This processing mode brings about several major drawbacks: 1. because the propeller blades are complex space curved surfaces, the manual grinding precision is difficult to ensure, the consistency is poor, and the working efficiency is low; 2. a large amount of dust is generated during grinding, the working environment is severe, the human health is not facilitated, and the labor intensity of workers is high.
The related document provides a scheme for automatically polishing the weight deviation of the propeller. Although this scheme can realize that the screw is heavy automatic to be polished, nevertheless there is obvious not enough: an annular track needs to be laid, and the occupied area is too large; the polishing head is generally arranged in a cantilever, the system rigidity is insufficient, and vibration is easy to generate during polishing, so that the processing precision is influenced; the working environment is severe, and the propeller is not high in adaptability to the size of the propeller by arranging the propeller on the bottom plate of the polishing device; in addition, the propeller rotates and moves through a driving device such as an electro-hydraulic push rod and the like, so that energy waste is easily caused for a large propeller, and resources are not saved; the rigid grinding tool cannot be well attached to a complex curved surface to realize accurate grinding.
