Embodiment Construction
[0018] A method for processing the blade surface of a propeller, referring to figure 1 , the blades are 100-200mm long and 0.2-1mm thick, and two adjacent blades form overlapped parts, including the following processing steps:
[0019] S1. Fix the propeller, use a dial indicator on the surface of the blade to be processed, and record the reading;
[0020] S2. Fill the space between two adjacent paddles with flexible adhesive material until the paddles are stretched outward under the force of the flexible adhesive material, and use a dial indicator to mark the surface of the paddle to be processed. The table ensures that the range of propeller opening is within the range that it can rebound;
[0021] S3. Carbide ball cutters are used to sequentially process the outer surfaces of the group of blades to completion;
[0022] S4. The flexible adhesive material is removed, and another set of paddles is selected, and steps S1-S3 are repeated until the surfaces of all paddles are pr...

Abstract
The invention relates to the technical field of sheet mechanical part surface processing, in particular to a processing method for the surface of a propeller blade and a processing method for the outside surface of the side walls of a U-shaped part. The invention aims to solve the technical problems of strong vibration and low accuracy during surface processing of an existing thinner propeller blade and the side wall of the U-shaped part. The specific scheme is shown as follows that the processing method comprises the steps of firstly, turning on a meter for recording to the basic value, and then filling flexible adhesive materials in a space between the adjacent blades or side walls till the blades are expanded outwards under the force effect of the flexible adhesive materials; ensuing that the expansion amplitude of the blades is within the range in which the blades can rebound with a dial indicator on the surface, to be processed, of the blades and or the side walls; and then processing the surface. In this way, by utilizing the performance of the flexible adhesive materials, the vibration and tool recession can be reduced effectively, and the processing accuracy is improved.
Description
technical field [0001] The invention relates to the technical field of surface processing of sheet-shaped mechanical parts, in particular to a method for processing the surface of a blade of a propeller and a method for processing the outer surface of a side wall of a U-shaped part. Background technique [0002] The propeller is a device that rotates in the air or water and converts the rotational power of the engine into propulsion, such as figure 1 As shown, it generally consists of a hub 1 and blades 2, which are widely used in propellers of airplanes and ships. The efficiency of the propeller is affected by geometric parameters such as diameter, number of blades, solidity, and blade angle. The propeller material is mainly made of aluminum alloy. With the improvement of product performance and the improvement of lightweight requirements, in order to further improve the efficiency of propellers, propellers are gradually developing in the direction of large diameter, thin...
