Manufacturing method of blade for centrifugal aeration blower diffuser and positioning tool for same

Abstract

The invention discloses a manufacturing method of a blade for a centrifugal aeration blower diffuser and a positioning tool for the same. The manufacturing method sequentially comprises the following machining procedures of: 1), roughly milling four sides of the blade and a process lug; 2), carrying out finish milling on the molded line of the blade; 3), adopting the positioning tool, carrying out wire-electrode cutting to remove the process lug; 4), grinding the top surface of the blade; 5), adopting the positioning tool, beneficially turning a positioning shaft by a turning lathe and cutting off the end surface of the process lug; 6), trimming and turning an overlap by a bench worker and milling a knuckle radius between two molded lines at two ends of the blade; 7), mounting a turning tool to drill a threaded bottom hole; 8), tapping and removing burrs by the bench worker; and 9), carrying out comprehensive detection. The manufacturing method and the positioning tool have the advantages that the procedures are arranged reasonably, and the machining quality and the machining efficiency can be effectively improved.

Description

technical field [0001] The invention relates to a manufacturing method of a blower diffuser blade and a positioning tool thereof, in particular to a manufacturing method of a centrifugal aeration blower diffuser blade and a positioning tool thereof. Background technique [0002] At present, the existing centrifugal aeration blower diffuser blade manufacturing method has a total of 8 processes, which are: 1), rough milling blade square and process bracket; 2), fine milling blade shape line: 3), wire cutting Remove the process strap; 4), lathe positioning shaft; 5), the fitter repairs the turning flash and the transition radius between the two ends of the milling blade; 6), drills the threaded bottom hole on the lathe; 7), the fitter Tapping and deburring; 8), comprehensive inspection. [0003] Although the diffuser blades of the centrifugal aeration blower can be manufactured according to the above-mentioned manufacturing method, the method for manufacturing the diffuser bla...

AI Technical Summary

Problems solved by technology

[0003] Although the diffuser blades of the centrifugal aeration blower can be manufactured according to the above-mentioned manufacturing method, the method for manufacturing the diffuser blades of the centrifugal aeration blower has the following disadvantages: 1. In the case of non-parallel process, the process 1) Next, process 2) is used to finely mill the profile of the blade, so that the line profile of the blade cannot be guaranteed, thus affecting the positioning accuracy of the tooling

2. When wire cutting is used in process 3), the roughness and parallelism cannot be guaranteed, which affects the dimensional tolerances of all levels on the positioning shaft and the guarantee of blade thickness during finishing turning, causing the blade to exceed the assembly gap
