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

[0001] technical field [0002] 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 [0003] At present, the existing centrifugal aeration blower diffuser blade manufacturing method has a total of 8 processes, which are: 1), rough milling of the blade square and crafting; 2), fine milling of the blade line; 3), wire cutting Removing the crafting tool; 4), the positioning shaft of the tool car on the car; 5), the fitter repairing the turning flash and the transition radius between the two molded lines at both ends of the milling blade; 6), drilling the threaded bottom hole on the car tool; 7) , Fitter tapping and deburring; 8), comprehensive inspection. [0004] Although the centrifugal aeration blower diffuser blade can be manufactured according to the above-mentioned manufactu...

AI Technical Summary

Problems solved by technology

[0004] Although the centrifugal aeration blower diffuser blade can be manufactured according to the above-mentioned manufacturing method, the method for manufacturing the centrifugal aeration blower diffuser blade has the following disadvantages: 1. In the process 1), the process blades are not parallel. 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

[0005] 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
