Abstract
The invention belongs to the technical field of mechanical connection pieces, and relates to a riveting nut suitable for light and heavy loads. The nut comprises a nut body, wherein the nut body is a hollow cavity provided with openings at two ends; internal threads are arranged in the cavity; the nut body comprises a nut cap head with an integral structure and a riveting part; the riveting part is sequentially provided with a first step and a second step outwards from the root part of the nut cap head; the first step and the second step are formed through necking down; a spline is arranged on the outer cylindrical surface of the first step, which is near to one side of the nut cap head; and a circular insertion groove is formed in the outer cylindrical surface of the inner side of the second step. The nut has the advantages of good concentricity of connection with a plate piece, no change of various mechanical and chemical performances in the connection process, firmness in connection and difficulty of desoldering and cracking; and the nut is applied in various heavy-load connections in aviation, railway, vehicle and the like.
Description
Technical field
The invention belongs to the mechanical fastener technical field, refer in particular to a kind of riveting nut that is applicable to weight load.
Background technique
Used set screw nut mostly is to connect with welding manner on the existing automotive seat sheet metal part, therefore the decentraction, nut deflection, nut that causes easily nut and carrier member by electric current puncture, screw thread goes to pot and nut is changed etc. because of the thread-rolling screw tooth distance of being heated, therefore meet with into a large amount of nuts hard waste, do over again and scrap, increased cost of production, caused the waste of resource and the waste in man-hour, and therefore production capacity and efficient be affected also; Therefore common self-clinching nut is confined on static load and the underloading, and the performance index such as every intensity are on the low side, can not adapt to the heavy load of automotive seat connection part, the needs of alternate load occasion.
Summary of the invention
The purpose of this invention is to provide and a kind of nut is connected to the various stable mechanical performance on the sheet metal part, the riveting nut that is applicable to weight load of accurate positioning.
The object of the present invention is achieved like this:
A kind of riveting nut that is applicable to weight load, comprise nut body, described nut body is the hollow cavity of both ends open, be provided with internal thread in the described cavity, described nut body comprises nut cap head and the caulking part of integral structure, described caulking part outwards is disposed with first step and the second step that necking down forms by the root of nut cap head, be provided with spline on the external cylindrical surface of the first step of the close first side of nut cap, be provided with the embedded groove of annular on the external cylindrical surface of second step inboard.
The external diameter of above-mentioned nut cap head is greater than the external diameter of spline, and the external diameter of spline is greater than the external diameter of second step, and the internal diameter of spline is more than or equal to the external diameter of first step.
The profile of tooth of above-mentioned spline is triangle or trapezoidal.
Above-mentioned embedded groove is vee gutter or rectangle groove.
The outside diameter of above-mentioned vee gutter is large, inside diameter is little.
Above-mentioned nut body is made with metallic material.
The present invention compared to existing technology outstanding and useful technique effect is:
After the spline that the present invention arranges and embedded groove embed plate, the plastic deformation of backup plate spare self embeds in the embedded groove of riveting nut, be difficult to extract easily and rotate, improved the stability of nut after embedding plate, and in the connection procedure of plate, pushed by External Force Acting physics fully, various machineries and chemical property are constant, the needs that adapted to weight load, alternate load occasion, pollution-free, low energy consumption, efficient is high, can be widely used in all kinds of heavy loads such as aviation, railway, vehicle and connect.
Description of drawings
Fig. 1 is partial sectional view of the present invention.
Fig. 2 is the right elevation of Fig. 1.
Embodiment
The invention will be further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-2:
A kind of riveting nut that is applicable to weight load, comprise nut body, described nut body is the hollow cavity of both ends open, be provided with internal thread 5 in the described cavity, described nut body comprises nut cap head 1 and the caulking part of integral structure, described caulking part outwards is disposed with first step 6 and the second step 2 that necking down forms by the root of nut cap head, be provided with spline 3 on the external cylindrical surface of the first step 6 of the close first side of nut cap, be provided with the embedded groove 4 of annular on the external cylindrical surface of second step 2 inboards.
The outer diameter D 1 of above-mentioned nut cap head 1 is greater than the outer diameter D 2 of spline 3, and the outer diameter D 2 of spline 3 is greater than the outer diameter D 4 of second step 2, and the internal diameter of spline 3 (tooth root diameter of a circle) is more than or equal to the outer diameter D 3 of first step 6.
The profile of tooth of above-mentioned spline 3 is triangle or trapezoidal.
Above-mentioned embedded groove 4 is vee gutter or rectangle groove.
The outside diameter of above-mentioned vee gutter is large, inside diameter is little.
Above-mentioned nut body is made with metallic material.
Use of the present invention, the external diameter of the second step 2 of riveting nut of the present invention equates with the internal diameter of the circular hole of the plate that is connected, be installed in the second step 2 of riveting nut of the present invention in the circular hole of plate together with embedded groove 4, after inspection center's line position is correct, all be pressed into spline 3 in the plate with stamping press, make the outer corresponding top splenium generation plastic deformation with spline 3 of the endoporus of plate, plastic deformation is partially submerged in the described embedded groove 4, so that plate and the present invention link together, and prevent from extracting along the axial direction of riveting nut, and spline 3 snaps in and plays the effect of rotating of preventing in the plate, because the process that connects is to use stamping press and specialized mould, the circular hole of plate and the good concentricity of riveting nut, make nut indeformable in the riveted joint process, avoided original welding temperature height and changed the various machineries of riveting nut and the deficiency of chemical property, and the soundness of riveting nut after embedding plate is better, has avoided welding the generation of the problems such as nonstandard easy sealing-off and crackle.
When certainly adopting the present invention to be connected with plate, the hardness that generally will choose nut body is higher than the hardness of plate, so that plate generation plastic deformation connects.
Above-described embodiment is preferred embodiment of the present invention only, is not to limit according to this protection scope of the present invention, so: all equivalences of doing according to structure of the present invention, shape, principle change, and all should be covered by within protection scope of the present invention.
