Description

Assembly structure of aluminum material part and steel insert

The present invention relates to a structure in which different materials are assembled with each other, and more particularly, to a structure in which an aluminum part and a steel insert are assembled with each other.

In general, components such as suspension and chassis of a vehicle have been mainly using steel parts to have sufficient rigidity, but recently, many parts of aluminum are used for high quality and light weight of a vehicle. It is a trend.

Since aluminum parts are not suitable for giving a large torque due to their physical properties, the aluminum parts are not directly fastened to the counterpart. Instead, the aluminum parts are fastened to the counterpart and the structure in which the steel insert is assembled to the aluminum parts.

That is, the steel insert is pressed into the aluminum part to fabricate a structure in which the aluminum part and the steel insert are assembled, and by assembling an assembly member such as a bolt or a screw to the steel insert, the assembly structure and the mating part of the aluminum part and the steel insert Will be used to fasten each other.

However, conventional structures in which the steel insert is simply assembled by pressing the steel insert into the aluminum part have a problem in that the steel insert is easily separated from the aluminum part due to the soft nature of the aluminum part.

Accordingly, the present invention is to assemble the aluminum parts and steel inserts to improve the durability and increase the service life of the aluminum parts and steel inserts so that the assembly of the aluminum parts and steel inserts can be made more robust. The purpose is to provide a structure.

The assembly structure of the aluminum part and the steel insert of the present invention for achieving the above object is a separation prevention groove formed to have a diameter larger than the diameter of the press-in groove in the press-in groove, one side of the press-in groove, the press-in groove An aluminum part integrally provided and protruding toward the center of the press-in groove and having a plurality of anti-rotation ribs provided along the circumferential direction of the press-in groove; A cylindrical body inserted into the press-in groove, an end stop formed integrally with one end of the cylindrical body and fitted into the release preventing groove, and a steel insert having a plurality of rib grooves into which the rotation preventing rib is fitted; It is characterized by.

According to the present invention, as the assembly of the aluminum component and the steel insert becomes more robust, the durability of the assembly structure of the aluminum component and the steel insert can be greatly improved, and the service life can be increased.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 are views of the assembly structure of the aluminum part and the steel insert according to the invention.

As shown, the aluminum part 10 is formed with a press-fitting groove 11 opened to one side, and at the inner end of the press-fitting groove 11, the separation preventing groove 12 is formed along the circumferential direction of the press-fitting groove 11. It is formed integrally.

Here, the diameter (D2) of the separation prevention groove 12 is formed larger than the diameter (D1) of the press-in groove 11, whereby the press-in groove 11 and the separation prevention groove 12 is It is formed to have a differential stepped cross section.

In addition, the C is provided in the press-in groove 11 integrally and protrudes toward the center of the press-in groove 11 and a plurality of rotation preventing ribs 13 provided along the circumferential direction of the press-in groove 11. It is configured to include more.

Here, the anti-rotation rib 13 is provided so that one end is located in the separation prevention groove 13 while each is disposed along the longitudinal direction of the indentation groove (11).

In addition, the steel insert 20 is formed of a cylindrical body 21 inserted into the press-in groove 11 and a separation prevention jaw formed integrally with one end of the cylindrical body 21 and fitted into the release preventing groove 13. 22 and a plurality of rib grooves 23 into which the anti-rotation ribs 13 are fitted.

Here, the rib groove 23, the one side is opened in the separation prevention jaw 22 along the longitudinal direction of the steel insert 20 and the other side is cut in a straight line to a position adjacent to the end of the cylindrical body 21 Is formed.

On the other hand, the diameter (D1) of the press-in groove 1 in the aluminum part 10 is formed to the same size as the diameter (D3) of the cylindrical body 21 in the steel insert 20, the aluminum part ( 10, the diameter D2 of the release preventing groove 13 is formed to be the same size as the diameter D4 of the release preventing jaw 22 on the steel insert 20.

In this case, since the diameter D4 of the release stop 22 is larger than the diameter D1 of the press-fit groove 1, the release stop 22 may not be inserted into the press-fit groove 1. Do.

Accordingly, when the cylindrical body 21 is elastically retracted, the diameter D4 of the separation prevention jaw 22 is reduced. At this time, the diameter D4 of the separation prevention jaw 22 is reduced to the indentation groove 11. It becomes smaller than the diameter (D1) of the), and in this way the diameter (D4) of the separation prevention jaw 22 is smaller than the diameter (D1) of the indentation groove 11 in the state that the separation prevention jaw (22) It is inserted into the press-in groove 1.

In addition, when the separation prevention jaw 22 inserted into the indentation groove 1 is positioned in the separation prevention groove 13, the separation prevention jaw 22, which has been elastically retracted to have a diameter D4, becomes smaller than the restoring force. By restoring to the original shape by the, the departure prevention jaw 22 is a form fitted into the departure prevention groove (13).

3 illustrates an assembly structure in which the aluminum insert 10 and the steel insert 20 are assembled together by pressing the steel insert 20 into the pressing groove 11.

When the steel insert 20 press-fitted into the press-fitting groove 11 is assembled with the aluminum part 10, the release inserting jaw 22 is inserted into the release preventing groove 13 so that the steel insert 20 is inserted. The indentation groove 11 of the aluminum part 10 does not fall out in the direction of the arrow M1 shown.

In addition, when the aluminum component 10 and the steel insert 20 are assembled, the rotary ribs 13 are inserted into the rib groove 23, so that the steel insert 20 is pressed into the press groove. It becomes impossible to rotate in (11).

Therefore, in the embodiment of the present invention, since the assembly of the aluminum component 10 and the steel insert 20 is made more robust, the durability of the assembly structure of the aluminum component 10 and the steel insert 20 is greatly improved. In addition, there is an advantage that can increase the service life.
