Abstract

The invention discloses a propeller blade shape modification tool. The problem that as for an existing shape modification method, accurate positioning of the rotating angle of a propeller blade is difficult is solved. A standard mode of the blade subjected to shape modification is input into a computer in advance, blade shape modification is shot in real time on site, and images obtained through shooting are compared with images of the standard model in the computer to find out errors so as to guide on-site operators to conduct blade shape modification. The blade subjected to shape modification is fixed to a propeller supporting screw of a propeller supporting screw rectangular base, accurate rotation of the blade subjected to shape modification is achieved by accurately backwards rotatingthe propeller supporting screw rectangular base, and accurate rotation of the rectangular base is achieved by means of the method that ratchet grooves which are annularly formed in the front-back direction are formed in the hole inner side walls of horizontal through holes formed in the propeller supporting screw rectangular base in the left-right direction, so that the on-site shot images of theblade subjected to shape modification are highly consistent with the standard images stored in the computer, and on-site shape modification is accurately guided.

Description

technical field [0001] The invention relates to a tool for repairing blades with complex curved surfaces, in particular to a tool for 3D scanning detection when polishing and repairing blades of propellers. Background technique [0002] After the propeller is processed and shaped, it is necessary to polish and modify the tip, blade and hub of the propeller. When polishing and repairing, it is necessary to perform 3D scanning on the formed propeller, input the scanned 3D image into the computer, and compare it with the standard model in order to find out the error and provide a basis for repair. During the trimming process, the camera is fixed on one side of the trimming bracket. When trimming a certain blade, it is necessary to adjust the angle of the blade in a small range so that the camera can obtain the angle of the blade at different angles. The image of the blade is compared with the standard 3D model stored in the computer to obtain the real-time repair error of the ...
