Description
Technical Field
The utility model relates to a nut technical field especially relates to an interior step flange nut.
Background
The automobile threaded fasteners are applied to many fields, and one common automobile model has thousands of fasteners which are only assembled in a main engine plant, and the fastening is essentially realized by utilizing the axial force generated after being screwed down to achieve the purpose of connection and fixation.
However, in some applications, the wall thickness of the fastened part of the component is very thin, for example, about 2mm, and the stress length of the bolt is very small in these applications, and the bolt is easily subjected to overload breakage during assembly or use, especially in the chassis area.
Simultaneously, to the application of welding bolt on the cooperation automobile body, the welding bolt screw thread can adhere to the one deck paint after the application, when using the nut assembly of ordinary screw thread, paint piles up probably to appear, forms false moment scheduling problem.
Therefore, a stepped nut needs to be designed to increase the stress length of the bolt, and a scrap scraping structure is arranged, so that the nut and the welding bolt can be assembled conveniently, and the purpose of solving the problems is achieved.
Disclosure of Invention
The utility model aims at providing a flange nut with inside stair structure, scrape bits structure for solve cooperation welding bolt, and assembly and the service problem that appears easily under the very thin condition in spare part by fixed position.
In order to solve the technical problem, the utility model discloses an adopt following technical scheme to realize:
an inner step flange nut comprises a nut body which is formed by a wrenching part 1 and a flange part 2, wherein a through hole is formed in the nut body in a penetrating mode;
the flange part 2 is arranged at one end of the wrenching part 1;
the through hole is formed by a unthreaded hole section 3 and a threaded hole section 4, the unthreaded hole section 3 is arranged at one end with the flange part 2, and the threaded hole section 4 is arranged at the other end;
the aperture of the unthreaded hole section 3 is larger than that of the threaded hole section 4, and a step surface 5 is formed at the joint.
Further, a plurality of axially extending scraping grooves 6 are circumferentially formed on the inner surface of the threaded hole section 4.
Further, the number of the scraping grooves 6 is three.
Further, the wrenching portion 1 is a hexagonal nut.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model provides an inner step flange nut, which increases the length of the bolt stress by arranging the step in the nut, and reduces the risk of the bolt fracture caused by overload in the assembling process;
the utility model provides a pair of interior step flange nut scrapes the bits structure through the inside setting of nut body, realizes utilizing the rotary cutting power of nut body self to clear away the lacquer mud obstacle on welding bolt surface, has made things convenient for the assembly of car after the application.
Drawings
The invention will be further described with reference to the accompanying drawings:
FIG. 1-1 is a schematic view of a forward structure of an internally stepped flange nut;
FIGS. 1-2 are schematic views of a rear view of an internally stepped flange nut;
FIG. 2 is a cross-sectional view of an internally stepped flange nut;
in the above figures: 1. the hole-drilling tool comprises a wrenching portion, 2 flange portions, 3 smooth hole sections, 4 threaded hole sections, 5 step surfaces and 6 scraping grooves.
Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the following detailed description of the present invention is made with reference to the accompanying drawings, and it is obvious that the described embodiments are some, not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-1, fig. 1-2, and fig. 2, the present embodiment provides an inner step flange nut, including a nut body formed by a wrenching portion 1 and a flange portion 2, wherein the nut body is provided with a through hole therethrough;
the flange part 2 is arranged at one end of the wrenching part 1; the wrenching part 1 is a universal hexagon nut.
The through hole is formed by a unthreaded hole section 3 and a threaded hole section 4, the unthreaded hole section 3 is arranged at one end with the flange part 2, and the threaded hole section 4 is arranged at the other end;
the aperture of the unthreaded hole section 3 is larger than that of the threaded hole section 4, and a step surface 5 is formed at the joint. In the actual assembling process of the bolt, especially when the bolt is applied to the chassis area, the stress length of the bolt can be increased, and the risk of breakage of the bolt due to overload in the assembling process is reduced.
And a plurality of axially extending scraping grooves 6 are formed in the circumferential direction of the inner surface of the threaded hole section 4. The rotary cutting force of the nut body can be utilized to remove paint mud obstacles on the surface of the welding bolt, and the assembly of an automobile after coating is facilitated.
The number of the scraping grooves 6 is three, and the number of the scraping grooves 6 can be determined according to the actual size and application condition of the nut.
The nut is simple and easy to manufacture, low in cost, convenient to use, simple in procedure and capable of remarkably improving assembling quality and assembling efficiency.
