Referring to fig. 3, fig. 3 is a schematic structural view of a nut 3 welding assembly according to an embodiment of the present invention.
As shown in fig. 3, the nut 3 welding assembly in this embodiment includes a main body 1, a reinforcing plate 2 and a nut 3, specifically, the main body 1 includes a U-shaped beam, that is, the cross section of the main body 1 is U-shaped, and forms a U-shaped groove, including a U-shaped bottom 11, a first side wall 12 and a second side wall 13, and in fig. 3, the U-shaped beam has flanges 14 along the edges of the first side wall 12 and the second side wall 13 in the length direction, which can facilitate connection with other components. The U-shaped beam can be applied to structures such as a crossbeam, an upright post and the like, is widely applied, has the advantages of light weight and is convenient for installing various installation parts, such as a wire harness, brackets of various functional parts and the like, and the nut 3 is used for fastening the installation parts and the main body part 1. Of course, fig. 3 is only an example of the main body 1, and any structural member requiring the welding of the nut 3 can be theoretically applied to the present embodiment, for example, the main body 1 has a flat plate structure.
As can be understood in conjunction with fig. 4 and 5, fig. 4 is a cross-sectional view taken along line a-a of fig. 3; fig. 5 is an enlarged view of a portion B in fig. 4.
The main body member 1 is provided with a nut positioning hole 1a, and the nut positioning hole 1a is matched with the nut 3, namely, the hole diameter of the nut positioning hole 1a is basically equal to the hole diameter of a screw hole 3a of the nut 3 and is slightly larger than the hole diameter of the screw hole 3a of the nut 3, so as to meet the corresponding tolerance requirement, thereby ensuring that after the nut 3 is welded on the main body member 1 corresponding to the nut positioning hole 1a, a matched bolt can penetrate through the nut positioning hole 1a of the main body member 1 and be screwed into the nut 3, and the fastening purpose is achieved. The aperture of the nut positioning hole 1a in fig. 5 is denoted as D2.
In addition, the reinforcing plate 2 also needs to be welded to the main body member 1, the reinforcing plate 2 in this embodiment is provided with a through hole 2a, the through hole 2a has a hole diameter D3 shown in fig. 5, and the nut 3 needs to pass through the through hole 2a and be welded to the main body member 1, that is, one end of the nut 3 facing the main body member 1 is located in the through hole 2a of the reinforcing plate 2, unlike the scheme of welding the nut 3 and the reinforcing plate 2 to form a nut 3 welded part in the prior art, the nut 3 and the reinforcing plate 2 in this embodiment are not welded, but are welded to the reinforcing plate 2 directly to the main body member 1.
In this embodiment, the nut positioning hole 1a and the nut 3 screw hole 3a formed in the main body 1 have the same diameter, and at least one end of the nut 3 facing the main body 1 can pass through the through hole 2a of the reinforcing plate 2, so that the diameter of the through hole 2a is larger than the diameter of the nut positioning hole 1a and the diameter of the nut 3 screw hole 3 a. Specifically, as shown in fig. 5, projected in the radial plane of the passage hole 2a in projection in the axial direction of the passage hole 2a, the threaded hole 3a of the nut 3 and the nut positioning hole 1a on the body member 1 are both located in projection of the passage hole 2 a.
Referring to fig. 4, when the main body 1 comprises a U-shaped beam, the inside of the U-shaped groove of the U-shaped beam is the inside of the main body 1, and the opposite outside is the outside, and in this embodiment, the nut 3 and the reinforcing plate 2 are both welded to the inside of the U-shaped beam, so as to facilitate the installation of the fastening and mounting member at the outside.
As shown in fig. 3, the reinforcing plate 2 is also U-shaped and is fittingly attached to the inner side of the U-shaped beam, which is adapted to the main body 1 of the U-shaped beam, so that the strength of the main body 1 can be improved. Of course, the reinforcing plate 2 may have other structures, such as a plate structure attached to the U-shaped bottom 11 of the U-shaped beam, which may serve as a local reinforcement.
For the above embodiments, the main body 1 may be provided with at least one nut positioning hole 1a, the nut positioning hole 1a may be adaptively designed according to the assembly requirement, the number and specific size of the nut positioning holes 1a are not limited in the present scheme, and fig. 3 shows a plurality of nut positioning holes 1 a. Similarly, the number of the through holes 2a of the reinforcing plate 2 is not limited, and may be matched to the number of the nut positioning holes 1a in the region of the main body 1 covered therewith.
In addition, as a further alternative, in the present embodiment, it is preferable that the hole wall of the through hole 2a and the corresponding outer peripheral wall of the nut 3 have a predetermined pitch, and in the correspondence relationship herein, the pitch of the through hole 2a from the outer peripheral wall of the nut 3 in the hole diameter direction. As shown in fig. 5, the nut 3 and the through hole 2a are spaced apart from each other, so that the nut 3 can be easily welded to the body member 1 through the through hole 2a, and the assembly tolerance of the nut 3 can be satisfied, ensuring that the nut 3 and the nut positioning hole 1a are maintained in a matching relationship after welding.
The nut 3 welding assembly may also comprise the mounting member described above, which is fixed to the body member 1 by means of a bolt, the reinforcement plate 2 being located on one side of the body member 1, the bolt passing through the positioning hole from the other side of the body member 1 and being screwed into the nut 3. Specifically, referring to the main body member 1 of the U-shaped beam structure in fig. 3, the mounting member is fixed to the outer side of the main body member 1 by bolts, and the nut 3 and the reinforcing plate 2 are located on the inner side of the main body member 1.
This scheme still provides a nut 3 welding assembly's welding process, based on above-mentioned arbitrary nut 3 welding assembly, concrete step is as follows:
firstly, welding the reinforcing plate 2 on one side of the main body piece 1;
one end of the nut 3 is then welded to the main body member 1 through the through hole 2a of the reinforcing plate 2, on the same side of the main body member 1 as the reinforcing plate 2.
In the embodiment, the nut positioning hole 1a is always arranged on the main body 1, and according to different product model requirements, for the main body 1 which does not need to be provided with the reinforcing plate 2, the nut 3 can be directly welded on the main body 1 at a position corresponding to the nut positioning hole 1 a; for the body member 1 to be provided with the reinforcing plate 2, it is only necessary to weld the reinforcing plate 2 provided with the through hole 2a to the body member 1 and then weld the nut 3 to the body member 1 through the through hole 2 a. It can be seen that, in the present embodiment, for the installation of a kind of installation component, only one kind of hole is needed to be provided for the main body component 1, that is, only the nut positioning hole 1a is needed to be provided, and there is no need to provide the nut positioning hole and the passing hole at the same time as the first way of the background art, and the reinforcing plate 2 in the present solution also only needs to provide one kind of passing hole 2a, and the installation and installation are both simple.
In the above welding process, the reinforcing plate 2 is welded first, and then the nut 3 is welded, so that the nut 3 does not interfere with the welding of the reinforcing plate 2, for example, when the main body 1 is a U-shaped beam, at least two of the first side wall 12, the second side wall 13, and the U-shaped bottom 11 have the nut 3, when the reinforcing plate 2 is welded later, the nut 3 of the side wall and the U-shaped bottom interferes with the installation of the reinforcing plate 2, and the welding of the reinforcing plate 2 first is not limited by the position of the nut 3. It is to be understood that when only one side wall or only the U-shaped bottom 11 is provided with the nut 3, or the main body member 1 is of other structure such as a flat plate structure, and the fitting of the reinforcing plate 2 is not restricted by the nut 3, the welding sequence of the reinforcing plate 2 and the nut 3 is not limited. The method also comprises the following steps:
firstly welding the nut 3 on one side of the main body piece 1;
the reinforcement plate 2 is then welded to the main body 1 from the same side as the nuts 3, and is used to escape the corresponding nuts 3 through the holes 2 a.
The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts. It should be noted that, for those skilled in the art, it is possible to make various improvements and modifications to the present invention without departing from the principle of the present invention, and those improvements and modifications also fall within the scope of the claims of the present invention.
