Automatic sorting structure for projection-weld square nut

Abstract

The invention relates to the technical field of a novel automatic sorting structure for a projection-weld square nut. Specifically, a through slot for accommodating the projection-weld square nut is formed in the end surface of a fan-shaped plate; a sorting stop pin, an induction switch and a gas blowing hole are separately formed in the end surface and the bottom surface of the through slot; thefan-shaped plate is improved, so that the projection-weld nut which enters the through slot drops to the stop pin through self-gravity, and is matched with the induction switch and a gas source, a concave surface of a welded nut welding point bump is utilized for circulating and screening, and the screened and sorted welded nut welding point bump is consistent in direction, and therefore, the automatic sorting purpose is achieved. A fastening part is automatically connected for being the technology trend for existing car and household application. The novel automatic sorting structure solves the structural problem of automatically sorting projection-weld nuts, so that the nuts can be automatically projection-weld. According to the main technical scheme and the technical key point, the structure is matched with a detecting system, so that an integrated structure for projection-weld nut detecting, signaling, conveying and sorting is completed.

Description

technical field [0001] The invention relates to the technical field of a new type of automatic sorting structure for projection welding square nuts. Specifically, a through groove is provided on the end face of the fan-shaped plate, a cylindrical stop pin is arranged on the side of the through groove, and a proximity switch is arranged on the bottom of the groove. With the air source hole, when the through groove is at the bottom of the quadrangular pyramid silo, the through groove can accommodate some projection welding square nuts in an orderly manner. The projection welding square nuts that do not enter the through groove are peeled off, while some orderly projection welding square nuts entering the through groove slide from top to bottom by their own weight, and use the effective cooperation between the stop pin, the induction switch and the air source in the through groove , using the concave surface of the welding spot convex platform of the projection welding square nut...

Problems solved by technology

[0004] At the same time, with the development of the automobile manufacturing industry, the production capacity of the projection welding parts is getting higher and higher. In the past, the projection welding parts were only manually welded by nuts, screws and plates, so the welding efficiency was low and the labor intensity was high.
