Description
The present invention relates to a rivet nut unit, more particularly, to a rivet nut unit which is joined to at least one plate member and integrates the functions of a nut to reduce a work process and a cycle time and to improve a fastening force with a plate material will be.
In general, the mechanical fastening of various body panels made of different materials in a vehicle makes the connection with other parts accurate and robust by using weld nuts and bolts.
Such a mechanical fastening method has a disadvantage in that the welding process in which the weld nut is positioned on the basis of the holes formed on one side of the single piece panel which can be welded, and then welding is performed using a projection welding machine or the like.
In addition, since the welded nuts welded through the projection welding are limited to the steel material, it is necessary to connect the nuts in one or two overlapping steel plates having the steel material to energize the nuts. However, Value, and pressing force becomes difficult.
In recent years, non-ferrous metal materials such as aluminum have been applied in accordance with the trend of weight reduction of the vehicle body. Since there is a part to be applied only to the aluminum as the material of the body of the vehicle and a part to which aluminum and steel are applied simultaneously, It is difficult to mount the weld nut through the projection welding to the plate material, and a separate nut mounting method is required.
In order to solve the disadvantages of the weld nut, a rivet joint or a screw fastening method is applied by a mechanical fastening method. However, in order to keep the fastening force by the weld nut and the bolt, So that a large number of rub-out points or screw fastening portions must be formed unnecessarily.
The matters described in the background section are intended to enhance the understanding of the background of the invention and may include matters not previously known to those skilled in the art.
SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to solve at least the above problems in the prior art. To improve workability and productivity, and to increase the fastening force of laminated heterogeneous plate materials.
In order to achieve the above object, a rivet nut unit according to an embodiment of the present invention is a rivet nut unit in which a bolt is fastened while riveting the plate members by being riveted to at least one plate member, And a through hole is formed in the center of the head portion corresponding to the hole. And an end portion integrally formed from the one surface of the head portion and inserted into the hole, the end portion being inserted and protruded into the hole to be bent to the other surface of the plate member during riveting to couple the head portion to the plate member, And an insertion portion formed therein.
The insertion portion may be formed in a hollow cylindrical shape corresponding to the through hole.
The slot may be formed to extend from one end of the insertion portion toward the other end connected to the head portion, and may be formed at a position spaced apart from the outer circumference of the insertion portion by a predetermined angle.
The slots may be spaced at an angle of 120 degrees along the circumference of the insert.
The head part may be integrally formed with at least one support part on one surface corresponding to one surface of the plate member.
The support portion includes a plurality of first support protrusions formed radially from an outer peripheral surface of the insertion portion toward an outer peripheral surface of the head portion; And a plurality of second support protrusions formed along the periphery of the head portion between the respective first support protrusions.
The first support protrusions may be formed on one surface of the head portion so as to be spaced apart at an angle of 60 degrees along the circumferential direction.
The second support protrusions may be circularly rounded from the outer circumferential surface of the head portion toward the insertion portion, and may be formed at an angle of 60 degrees along the circumferential direction of the head portion.
The support portion may further include third support protrusions formed by interconnecting one side of the head portion and one side of the outer circumferential surface of the insertion portion in correspondence with the respective second support protrusions.
The third support protrusion may be formed in a triangular shape formed downward from the one surface of the head portion toward the outer peripheral surface of the support portion.
The support portion may further include a third support protrusion formed by interconnecting each of the first support protrusions between each of the second support protrusions and the insertion portion.
The third support protrusion may be formed in a circular ring shape protruding from one surface of the head portion.
The support portion includes a third support protrusion formed by interconnecting each of the first support protrusions between each of the second support protrusions and the insertion portion; And a fourth support protrusion formed by mutually connecting one side of the head portion and one side of the outer circumferential surface of the insertion portion at positions corresponding to the respective second support protrusions.
The third support protrusion may be formed in a circular ring shape protruding from one surface of the head portion.
The fourth support protrusion may be formed in a triangular shape that is inclined downward from the one surface of the head portion toward the outer circumferential surface of the support portion.
The support portion includes a plurality of first support protrusions formed to be inclined in a spiral direction from an outer peripheral surface of the insertion portion toward an outer peripheral surface of the head portion; And a plurality of second support protrusions formed along the periphery of the head portion and connected to the other end of each of the first support protrusions, one end of which is connected to one side of the outer circumferential surface of the support portion.
The first support protrusions may be formed on one surface of the head portion so as to be spaced apart at an angle of 60 degrees along the circumferential direction.
The second support protrusions may be circularly rounded from the outer circumferential surface of the head portion toward the insertion portion, and may be formed at an angle of 60 degrees along the circumferential direction of the head portion.
The plate members may be arranged in a state that two plate members formed of different materials are overlapped with each other.
As described above, according to the rivet nut unit according to the embodiment of the present invention, by joining at least one plate member and integrating the functions of the nut, the work process can be reduced and the cycle time can be reduced to improve workability and productivity It is effective.
Further, by joining the plate members together and increasing the fastening force with the plate member in a state in which the plate members made of different materials are stacked and overlapped, the joint rigidity of each plate member is improved, There is also an effect that can be concluded.
Further, by forming respective support portions having various shapes formed on the lower surface of the head portion contacting the plate member, there is also an effect of improving the tightening torque of the rivet nut unit coupled through each plate member.
In addition, since a slot is formed in the insertion portion inserted through the plate member, and a portion of the plate material corresponding to the slots is introduced, thereby forming a mechanical interlock interconnected with the insertion portion, the plate material is constrained There is also an effect.
In addition, the inserting portion exhibits a sufficient resistance force with respect to the rotating direction of the plate member, and the rivet nut unit can be prevented from rotating at the time of bolt fastening by restraining the plate member with a predetermined strength through the inserting portion, There is also an effect of further increasing the strength and bonding strength.
