Detailed Description
The technical problems to be solved, the technical solutions to be adopted and the technical effects to be achieved by the present invention will be clearer, and the technical solutions of the embodiments of the present invention will be further described in detail with reference to the accompanying drawings. As shown in fig. 1 to 3, the present invention provides a bolt joint structure for replacing a weld nut, including a nut bracket 1, a nut 2; the nut 2 can be placed in the nut support 1, a gap exists between the nut 2 and the nut support 1, and the nut 2 can move in the nut support 1; when the holes of the bolt and the nut 2 are not aligned, the nut 2 can freely move in all directions in the nut bracket 1 due to the existence of the gap until the holes are aligned and can be smoothly installed.
A cavity for placing the nut 2 is formed between the nut bracket 1 and the target piece 3; this cavity plays the effect of restriction nut 2 position on the one hand, makes it inject in the regulation region, and on the other hand plays the effect of location, inject bolt and 2 hole sites of nut in a definite position, and it just can be to going up the hole site to add removal nut 2 a little, makes the installation convenient and fast more.
The nut bracket 1 comprises a top seat 10, a first positioning bulge 11, a second positioning bulge 12, a third positioning bulge 13 and a fourth positioning bulge 14; the top seat 10 is provided with a waist-shaped hole 101;
the footstock 10 is respectively connected with an arc at one end of the first positioning protrusion 11, the second positioning protrusion 12, the third positioning protrusion 13 and the fourth positioning protrusion 14, and the other end of the first positioning protrusion 11, the second positioning protrusion 12 and the third positioning protrusion 13 are respectively fixedly connected with the target part 3. Adopt the circular arc to connect and to make nut 2 remove more in the same direction as smooth on the one hand, can effectively reduce the collide with and bump between nut 2 and the nut support 1, guarantee the integrity of each part, prolong each part life, on the other hand the circular arc is connected also more beautifully, has still guaranteed the effective clearance in the nut support 1, makes nut 2 remove more freely, and the kidney type hole 101 that the footstock was seted up is also for the removal of convenient nut 2 for the bolt is connected convenient and fast more with nut 2.
Further, the first positioning protrusion 11, the second positioning protrusion 12, and the third positioning protrusion 13 are equal in height, and the height of the nut 2 is smaller than the heights of the first positioning protrusion 11, the second positioning protrusion 12, and the third positioning protrusion 13. The first positioning bulge 11, the second positioning bulge 12 and the third positioning bulge 13 are equal in height, so that the nut bracket 1 and the target part 3 are connected in a positioning fillet welding mode, and the connection is more stable and reliable; the height of the nut 2 is less than the height of the first positioning bulge 11, the second positioning bulge 12 and the third positioning bulge 13, so that the nut 2 can be smoothly placed in the nut bracket 1.
Further, the height of the fourth positioning projection 14 is half of the height of the nut 2. The purpose is to facilitate replacement of the nut 2 when the nut 2 fails due to damage.
Further, the first positioning protrusion 11, the second positioning protrusion 12, and the third positioning protrusion 13 are fillet-welded to the target member 3. The connection is more stable and reliable.
Further, the shape of the nut 2 may be square, hexagonal. The application range of the nut 2 can be expanded, and the advantages of the structure can be more prominent.
Further, the inner diameter of the inner threaded hole 21 of the nut 2 is smaller than the width of the kidney-shaped hole 101 of the top seat 10. So that the bolt can be smoothly placed in the waist-shaped hole, and the connection between the bolt and the nut 2 is convenient.
Further, the top seat 10 and the first positioning protrusion 11, the second positioning protrusion 12, the third positioning protrusion 13, and the fourth positioning protrusion 14 may be connected by welding or integrally formed. Can select according to the mechanical properties requirement of material, integrated into one piece intensity is high, and welded connection structure is convenient and fast more.
Further, gaps are formed among the first positioning protrusion 11, the second positioning protrusion 12, the third positioning protrusion 13 and the fourth positioning protrusion 14. So that the moving space of the nut 2 is more sufficient and the connection of the bolt and the nut 2 is convenient.
Further, the surface of the target 3 is provided with a waist-shaped hole 101 identical to the top seat 10. So that the moving space of the nut 2 is more sufficient and the connection of the bolt and the nut 2 is convenient.
The working principle is as follows: when the space is narrow or the closed space needs to be connected by using the bolt and the nut 2, the bolt connection structure for replacing the welding nut can be selected. Firstly, forming a waist-shaped hole 101 on the outer surface of a target part 3, wherein the waist-shaped hole is the same as the top seat 10 of the nut bracket 1, and the width of the waist-shaped hole 10 is larger than the inner diameter of an internal threaded hole 21 of the nut 2; then, positioning the nut 2 to the inner surface of the target part 3 corresponding to the outer surface of the target part 3, so that the internal threaded hole 21 of the nut 2 is arranged at the center of the kidney-shaped hole 10; then, positioning the nut support 1 to the inner surface of the target part 3, enabling the internal threaded hole 21 of the nut 2 to be arranged at the center of the waist-shaped hole 101 in the top seat 10 of the nut support 1, and after positioning, performing fillet welding connection on the nut support 1 and the target part 3 by using a welding machine, so that the nut 2 is positioned in a cavity formed by connecting the nut support 1 and the target part 3; and finally, the bolt extends into the kidney-shaped hole 101 on the outer surface of the target part 3 and is aligned with the threaded hole 21 in the nut, if the hole positions are not aligned, the position of the nut 2 can be moved until the hole positions are aligned, and after the hole positions are aligned, the bolt is screwed by using a tool, so that the connection between the bolt and the nut 2 is completed. Therefore, the problem that the positions of the bolt and the welding nut are not aligned easily because the welding nut is fixed when the waist-shaped hole can only be opened because the waist-shaped hole can not be opened due to various limitations in the place where the waist-shaped hole needs to be opened on the target part is solved. A cavity for placing the nut 2 is formed between the nut bracket 1 and the target piece 3; this cavity plays the effect of restriction nut 2 position on the one hand, makes it inject in the regulation region, and on the other hand plays the effect of location, inject bolt and 2 hole sites of nut in a definite position, and it just can be to going up the hole site to add removal nut 2 a little, makes the installation convenient and fast more.
While the utility model has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the utility model. The present invention is not to be limited by the specific embodiments disclosed herein, and other embodiments that fall within the scope of the claims of the present application are intended to be within the scope of the present invention.
