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...

Embodiment 1

[0020] Embodiment 1: as figure 1 , 2 As shown, a method for manufacturing diffuser blades of a centrifugal aeration blower, the processing steps include: 1) Rough milling of blade squares and process straps; 2) Fine milling of blade profile; 3) Using positioning tooling , wire cutting to remove the process strap; 4), grinding the top surface of the blade; 5), using the positioning tool described in process 3), which is convenient for the lathe to turn the positioning shaft and cut off the end face of the process strap; 6), fitter repair the car Cut the flash and mill the transition radius between the two molded lines at both ends of the blade; 7) Drill the threaded bottom hole on the lathe; 8) The fitter taps the thread and deburrs; 9) Comprehensive inspection. Wherein, in the process 1), the parallelism of the blade rests is less than 0.05 mm.

[0021] In the present invention, process 1) is used as a reference when performing rough milling of the four sides of the blade an...
