Post-welding processing method for telemetering antenna

Abstract

According to a post-welding processing method for a telemetering antenna, after argon arc welding is conducted on a bottom plate and a radiation source, the following procedures are conducted in sequence: S1, crator polishing is conducted, specifically, crators on a welding part between the bottom plate and the radiation source are polished through an electric grinding wheel, then the welding part between the bottom plate and the radiation source is filed through a file, and finally abrasive leather is used for polishing, so that the welding part can be in smooth transition; S2, linear cutting is conducted, specifically, the circumferential and arc chamfers of the bottom plate are processed through linear cutting, and meanwhile connecting holes in the four corners of the bottom plate are processed through linear cutting; S3, R1.6 milling is carried out; and S4, shaping. The electric grinding wheel is adopted for polishing the crators, meanwhile, the file and the abrasive leather are combined for polishing, and the problem that the polishing efficiency is low when the file is independently adopted for filing is solved; and linear cutting is conducted firstly, then R1.6 processing is carried out, then shaping is carried out, the tedious operation that shaping is carried out firstly, then R1.6 filing is carried out to cause a certain degree of deformation, and then shaping is carried out is carried out in an existing processing technology is avoided, and the processing time is saved.

Description

technical field [0001] The invention relates to the technical field of fuze antennas, in particular to a post-welding processing method for a telemetry antenna. Background technique [0002] The telemetry antenna is the main part of the fuze antenna, which is connected by the base plate and the radiation source through argon arc welding. The processing flow of the telemetry antenna in the prior art is as follows: [0003] Pickling → cleaning → assembly → argon arc welding → grinding weld scars → shaping → filing R1.6 → reshaping → wire cutting → tightening all threads with screws matching the threaded holes of the bottom plate → shot blasting → screwing out Screw → storage. [0004] In the existing processing technology, the welding scar grinding method is as follows: use a file to polish the welding scar around the weld seam, then use a scraper to polish the weld scar around the weld seam, and finally use sanding to polish the welding part to a smooth transition. Due to ...

AI Technical Summary

Problems solved by technology

Reshaping→refining R1.6→reshaping operation is cumbersome, and the process arrangement is unreasonable

In the existing process, the repairing of R1.6 files is all done by hand, and the average time for repairing a product is 60 minutes, which is low in efficiency and labor-intensive, and it is difficult to guarantee the length direction dimension of the R1.6 fillet and R1.6
