Description

Technical Field

[0001] The utility model relates to the technical field of parts tapping processing, in particular to an automatic processing device for error-proof tapping of nut parts. Background Art

[0002] Tapping machine is a kind of mechanical processing equipment that processes internal threads, screws or teeth buckles on the inner side of the holes of various parts with different specifications of through holes or blind holes, such as machine housings, equipment end faces, nuts, flanges, etc. At present, a nut part needs to be processed in the actual production process. The thread is tapped by the station turntable column. The tapping is a single-station processing. The material is loaded by the vibrating disk, and the turntable rotates to discharge it. However, during processing, it is found that sometimes the material has been processed, but it is mixed with the unprocessed material. Therefore, it is necessary to screen it before processing. If manual methods are used, it will inevitably reduce efficiency and increase costs. Therefore, an airtight error-proofing structure is designed on the existing equipment mainly to avoid secondary tapping. Between the discharge port of the vibrating disk and the processing station, a detection structure is designed that can move up and down. The probe enters the inner diameter of the product and detects whether the product has been processed through the air flow rate. It has the function of automatically identifying and eliminating unqualified products. Utility Model Content
