The invention discloses a kind of Combined rivet, the rivet is hollow integral structure, is made up of in the axial direction canned paragraph and mobile section two parts, and connection is formed by prefabricated weak section between canned paragraph and mobile section；The canned paragraph, which is socketed in, to be thickeied in the pre-manufactured hole of part, in riveting process, canned paragraph and mobile section are broken at prefabricated weak section, mobile section riveting enters in the endoporus of canned paragraph, the wall thickness of canned paragraph and mobile section is collectively forming separately plus increased wall thickness layer, rivet are fixedly connected integrally by crimp with part.Partial thickening can be carried out for thin-walled parts by way of riveting, avoid realizing using processing modes such as welding, have and thicken the characteristics of simple and reliable.
Description
Technical field
The present invention relates to a kind of component of machine for being used to realize thin-walled parts partial thickening, and in particular to a kind of combined type
Rivet.
Background technology
In field of machining, it is sometimes desirable to other parts are installed and connected on thin-walled parts, thin-walled parts are general
For thickness below 2 millimeters, such thickness can not realize machining to reach reliable connection, such as processing screw thread or weldering
Connect；If ensureing the reliability of connection, primary selection is to increase the overall wall thickness of part, but this mode make it that product is whole
The increase of the weight and production cost of body at double, it is difficult to meet the design requirement of product.Another mode is to carry out local increasing
Thick processing, part thickeies the form that can use welding, but the solder joint for welding formation can cause the difficulty of following process.
The content of the invention
In view of this, the invention provides a kind of Combined rivet, can be entered by way of riveting for thin-walled parts
Row partial thickening, avoid realizing using processing modes such as welding, have and thicken the characteristics of simple and reliable.
A kind of Combined rivet, the rivet is hollow integral structure, in the axial direction by canned paragraph and mobile section two
It is grouped into, connection is formed by prefabricated weak section between canned paragraph and mobile section；The canned paragraph, which is socketed in, need to thicken part
In pre-manufactured hole, in riveting process, canned paragraph and mobile section are broken at prefabricated weak section, and mobile section riveting enters the interior of canned paragraph
The wall thickness of Kong Zhong, canned paragraph and mobile section is collectively forming separately plus increased wall thickness layer, rivet are fixed by crimp and part
Link into an integrated entity.
Further, for the ease of the assembling and positioning of rivet and part, on the outer circumference surface of the front end of the canned paragraph
It is machined with fixing structure.
Further, the endoporus of the canned paragraph is straight hole, and the excircle of the mobile section is taper surface.
Further, the taper in the upper conical face of the mobile section is 7 °.
Further, the material of the rivet is using ductility good copper or No. 45 steel.
Further, the endoporus of the mobile section is machined with the thread segment for connecting external structure.
Further, in order that rivet can for a long time be deposited and prevent from corroding, the surface cadmium plating of the rivet, the thickness of coating
Spend for 8-12 μm.
Beneficial effect：
The present invention can be achieved with handling the partial thickening of thin-walled parts by simple punching press action, simple in construction and easy
In processing and implement, substantially reduce the production cost of this class formation processing；Stability Analysis of Structures after riveting, there is good engineering
Application prospect.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the present invention；
Fig. 2 is the process schematic that the present invention is riveted with thin-walled parts；
Fig. 3 is the size relationship schematic diagram of the present invention.
Wherein, the prefabricated weak section of 1- canned paragraphs, 2- mobile sections, 3-, 4- thin-walled parts.
Embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1, the invention provides a kind of Combined rivet, the rivet is hollow integral structure, rivet
It is made up of in the axial direction canned paragraph 1 and the two parts of mobile section 2, fixing structure is machined with the outer circumference surface of the front end of canned paragraph,
It is threaded on the endoporus of mobile section 2；Connection is formed by prefabricated weak section 3 between canned paragraph 1 and mobile section 2.
The surface cadmium plating of rivet, the thickness of coating is 8-12 μm；The material of rivet is using ductility good copper or No. 45 steel.
As shown in Figure 2, when carrying out thickening processing for thin-walled parts 4, processing one is logical first on thin-walled parts 4
Hole, canned paragraph 1 is socketed in the through hole for the thin-walled parts 4 that need to thicken processing, and in riveting process, canned paragraph 1 and mobile section 2 are pre-
Make and be broken at weak section, the riveting of mobile section 2 enters in the endoporus of canned paragraph 1, and the wall thickness of canned paragraph 1 and mobile section 2 is collectively forming
Separately plus increased wall thickness layer, rivet are fixedly connected integrally by crimp with part.
As shown in Figure 3, the overall length of rivet is 9.5mm in embodiment, and the aperture of canned paragraph 1 is 9.4mm, fixing structure
External diameter is 13mm, and the big end external diameter of mobile section 2 is 11mm, and taper uses 7 °.
In summary, presently preferred embodiments of the present invention is these are only, is not intended to limit the scope of the present invention.
Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., it should be included in the present invention's
Within protection domain.
