Abstract
The utility model belongs to the technical field of mechanical joint elements, and relates to a riveting nut suitable for light load and heavy load. The riveting nut comprises a nut body which is a hollow cavity with openings at two ends, inner threads are arranged in the cavity, and the nut body comprises a nut cap and a riveting part which are of an integrated structure, wherein a first step and a second step formed in a necking down mode are sequentially and outwards arranged from the root portion of the nut cap and arranged on the riveting part, a spline is arranged on the outer cylindrical face, close to one side of the nut cap, of the first step, and an annular embedding groove is arranged on the outer cylindrical face on the inner side of the second step. The riveting nut has the advantages that connection concentricity of the nut and a board is good, various mechanical and chemical performance in the connecting process are not changed, connection is firm, desoldering and cracks can not be caused easily, and the nut can be applied to various heavy load connections in the fields of aviation, railways and vehicles.
Description
Technical field
The utility model belongs to the mechanical fastener technical field, refers 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 nut and carrier member easily 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 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 utility model provides and a kind of nut is connected the various stable mechanical performance on the sheet metal part, the riveting nut that is applicable to weight load of accurate positioning.
The purpose of this utility model is achieved in that
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, the external cylindrical surface of the first step of the close first side of nut cap is provided with spline, and the external cylindrical surface of second step inboard is provided with the embedded groove of annular.
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 big, inside diameter is little.
Above-mentioned nut body is made with metallic material.
The utility model outstanding and beneficial technical effects compared to existing technology is:
After the spline that the utility model 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 effect physics fully, various machineries and chemical property are constant, the needs that adapted to weight load, alternate load occasion, pollution-free, low energy consumption, the efficient height 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 utility model.
Fig. 2 is the right elevation of Fig. 1.
Embodiment
The utility model is 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, the external cylindrical surface of the first step 6 of the close first side of nut cap is provided with spline 3, and the external cylindrical surface of second step 2 inboards is provided with the embedded groove 4 of annular.
The D outer diameter 1 of above-mentioned nut cap head 1 is greater than the D outer diameter 2 of spline 3, and the D outer diameter 2 of spline 3 is greater than the D outer diameter 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 D outer diameter 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 big, inside diameter is little.
Above-mentioned nut body is made with metallic material.
Use of the present utility model, the external diameter of the second step 2 of riveting nut of the present utility model 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 utility model 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 roof pressure portion generation plastic deformation with spline 3 of the endoporus of plate, plastic deformation is partially submerged in the described embedded groove 4, make plate and the utility model 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, avoid 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 problems such as nonstandard easy sealing-off and crackle.
When adopting the utility model to be connected with plate certainly, 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 utility model only, is not to limit protection domain of the present utility model according to this, so: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.
