Description
Technical Field
The utility model relates to the technical field of nuts, in particular to a press riveting nut for an automobile.
Background
With the development of automobile light-weight technology, the automobile body can be light-weight by adopting aluminum alloy materials and more nonmetallic parts, so that the weight of the automobile body is reduced to achieve better energy-saving and environment-friendly effects. The aluminum alloy car body mostly adopts an aluminum alloy profile framework combined skin structure, wherein the aluminum alloy profile is mainly welded and riveted in a connecting mode, the press-riveting nut is a riveting nut applied to a thin plate or a metal plate, the principle is that the press-riveting nut is pressed into a preset hole of the thin plate through embossed teeth, in general, the aperture of the preset hole is slightly smaller than that of the embossed teeth of the press-riveting nut, the press-riveting nut is extruded into the plate through pressure, plastic deformation is generated on the periphery of the hole, and a deformation is extruded into a guide groove, so that a locking effect is generated.
After the conventional press-riveting nut is used for a long time, the connection relation between the nut and the plate body becomes loose, so that the fastening effect on the assembly plate is reduced, and therefore, the press-riveting nut for the automobile is provided.
Disclosure of Invention
The utility model aims to solve the problem that the connection relation between a nut and a plate body becomes loose after the press-riveting nut is used for a long time, so that the fastening effect on an assembly plate is reduced, and provides the press-riveting nut for the automobile.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
the utility model provides a press-riveting nut for car, includes the nut body, the upper end fixedly connected with outer ring gear of nut body, a plurality of conical posts that are circular distribution of outer ring gear fixedly connected with, the upper end fixedly connected with taper piece of nut body, the taper piece is located outer ring gear, all be equipped with the hollow groove in nut body and the taper piece, fixedly connected with internal thread on the hollow groove inside wall.
Preferably, the tapered column is heat treated.
Preferably, the surface of the nut body is often galvanised.
Preferably, the lower end of the nut body is provided with a first arc chamfer.
Preferably, the upper end of the nut body is provided with a second arc chamfer.
The beneficial effects are that:
1. when the press-riveting nut body is used, the nut body is plugged into a prefabricated hole of a plate, when the nut body completely enters the prefabricated hole, the outer gear ring can be tightly clamped on the inner wall of the prefabricated hole, meanwhile, the conical column is deformed and props against the side wall of the upper end of the outer gear ring, so that the upper end of the conical column is embedded into the conical block, and the nut body is prevented from loosening;
2. the taper column is processed by heat treatment, so that the mechanical property of steel can be remarkably improved, the service life of machine parts is prolonged, the surface of the nut body is often galvanized, the overall attractive degree can be improved, the lower end of the nut body is provided with a first arc-shaped chamfer, the upper end of the nut body is provided with a second arc-shaped chamfer, the comfort level of a user in taking can be improved, and a certain attractive degree is improved.
