Abstract
Description
Technical Field
[0001] This utility model relates to the field of welding nut technology, specifically a high-end irregular-shaped welding nut. Background Technology
[0002] A weld nut is a nut designed for welding. It is typically made of a thick, weldable material suitable for welding. Welding is essentially turning two separate parts into a single unit. Metals are melted at high temperatures, mixed together, and then cooled. Alloys are often added during the process. The internal forces, acting as molecular bonds, generally result in a weld nut with greater strength than the base metal. Experimental welding parameters depend on the degree of fusion in the weld. Welding parameters are adjusted based on this fusion until defects are eliminated.
[0003] However, existing welded nut structures, in order to ensure that the nut can be used in conjunction with a wrench, do not have an external assembly structure designed to avoid interference with the use of the wrench. However, when splicing two sets of irregularly shaped nuts, the welding angle of the two sets of nuts needs to be adjusted. Since there is no fixed structure, it is difficult to accurately fix their center position. When splicing two sets of nuts, misalignment of the welding position is likely to occur, which affects the welding efficiency of the nut. To address this, we propose a high-end irregularly shaped welded nut. Summary of the Invention
[0004] To address the shortcomings of existing high-end irregular-shaped welding nuts, this utility model provides a high-end irregular-shaped welding nut with a first connecting plate and a second connecting plate installed inside the first nut and the second nut. This allows for splicing and limiting the first nut and the second nut before welding, and at the same time, it prevents the position of the first nut and the second nut from shifting during the rotation of the second nut. This improves the stability of the first nut and the second nut during the welding positioning process and solves the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: a high-end irregular-shaped welding nut, including a first nut and a second nut, a limiting sleeve is fixedly connected to the lower part of the first nut, a bolt is installed in the internal thread of the first nut, an installation hole is opened in the middle of one side of the first nut, a through hole is opened inside the first nut and the through hole passes through the interior of the installation hole, and a weld point is fixedly connected to the outside of the first nut.
[0006] Preferably, the first nut and the second nut have the same shape, and one side of the first nut and the second nut are in contact with each other.
[0007] Preferably, a transverse groove is provided on the outer lateral position of the first nut, and a first positioning pin is installed inside the transverse groove. The first positioning pin is located inside the transverse groove at the connection between the first nut and the second nut.
[0008] Preferably, the limiting cylinder has a positioning hole inside, and a positioning pin is provided inside the positioning hole.
[0009] Preferably, a first connecting plate and a second connecting plate are respectively installed inside the mounting hole formed between the first nut and the second nut, and the first connecting plate and the second connecting plate are circular.
[0010] Preferably, a second positioning pin is movably sleeved inside the through hole, and two sets of the second positioning pins pass through the interior of the second connecting plate and the second positioning pin in sequence.
[0011] Preferably, the side of the weld point is kept flush with the side of the first nut, and when the first nut and the second nut are installed in alignment, the weld points installed on the sides of the first nut and the second nut are in a close fit.
[0012] Compared with existing high-end irregular-shaped welded nuts, this utility model has the following beneficial effects:
[0013] 1. This high-end irregular-shaped welding nut has mounting holes on the outside of the first nut and the second nut. When welding at the connection between the first nut and the second nut, a first connecting plate and a second connecting plate are installed inside the mounting holes. The first connecting plate and the second connecting plate pass through the interior of the first nut and the second nut in sequence. At the same time, a second positioning pin is installed inside the through hole. The second positioning pin drives the first connecting plate and the second connecting plate to limit the position of the first connecting plate and the second connecting plate inside the first nut and the second nut. The first connecting plate and the second connecting plate drive the second nut to rotate. That is, the welding angle between the first nut and the second nut can be adjusted to improve the convenience of welding equipment.
[0014] This high-end irregular-shaped welding nut has weld points installed on the outside of the first nut. When the first nut and the second nut are aligned, the weld points on the outside of the first nut and the second nut are aligned. The weld points limit the stability of the equipment during welding and positioning. At the same time, the side of the weld point is kept in a state of overlap with the outside of the first nut. When the first nut is rotated, the weld point is prevented from interfering with the rotation of the equipment. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A high-end irregular-shaped welded nut includes a first nut 1 and a second nut 2. A limiting sleeve 3 is fixedly connected to the lower part of the first nut 1. The limiting sleeve 3 is machined to position the first nut 1. A bolt 5 is installed on the internal thread of the first nut 1. An installation hole 8 is opened in the middle of one side of the first nut 1. The installation hole 8 limits the position of the first connecting plate 10 and the second connecting plate 11 to improve the stability of positioning when the first nut 1 and the second nut 2 are spliced. A through hole 9 is opened inside the first nut 1, and the through hole 9 passes through the interior of the installation hole 8. A second positioning pin 12 is installed inside the through hole 9. The second positioning pin 12 drives the first connecting plate 10 and the second connecting plate 11 to splice and limit the position inside the first nut 1 and the second nut 2. A weld point 13 is fixedly connected to the outside of the first nut 1. The weld point 13 drives the welding treatment between the connection of the first nut 1 and the second nut 2.
[0024] Please see Figure 1The first nut 1 and the second nut 2 have the same shape. One side of the first nut 1 and the second nut 2 are in contact with each other. By controlling the contact of one side of the first nut 1 and the second nut 2 according to the different welding parts of the two sets of nuts, the welding device drives the connection of the first nut 1 and the second nut 2 to be welded.
[0025] Please see Figure 6 A transverse groove 6 is provided on the outer lateral position of the first nut 1. A first positioning pin 7 is installed inside the transverse groove 6. The first positioning pin 7 is located inside the transverse groove 6 at the connection between the first nut 1 and the second nut 2. When the first nut 1 and the second nut 2 are welded together, the first nut 1 and the second nut 2 are aligned and installed. At the same time, the transverse groove 6 on the outside of the first nut 1 and the second nut 2 remains flush. The first positioning pin 7 is installed inside the transverse groove 6. The first positioning pin 7 drives the connection between the two sets of first nuts 1 and second nuts 2 to limit the position between the first nut 1 and the second nut 2, so as to improve the position and maintain the stability of the positioning when the first nut 1 and the second nut 2 are arranged and installed.
[0026] Please see Figure 4 The limiting cylinder 3 has a positioning hole 4 inside, and a positioning pin is installed inside the positioning hole 4. By having a positioning hole 4 inside the limiting cylinder 3, and controlling the bolt 5 to be threaded into the inside of the limiting cylinder 3, the positioning pin installed inside the positioning hole 4 ensures stability when the first nut 1 and the bolt 5 are spliced together.
[0027] Please see Figure 4 A first connecting plate 10 and a second connecting plate 11 are respectively installed inside the mounting hole 8 between the first nut 1 and the second nut 2. The first connecting plate 10 and the second connecting plate 11 are circular. The first connecting plate 10 and the second connecting plate 11 are respectively installed inside the mounting hole 8 between the first nut 1 and the second nut 2. The first connecting plate 10 and the second connecting plate 11 are confined inside the first nut 1 and the second nut 2. When the second nut 2 is rotated, the first connecting plate 10 and the second connecting plate 11 drive the welding surfaces of the first nut 1 and the second nut 2 to keep them in a close fit. And when the welding angle of the first nut 1 and the second nut 2 changes, the position is prevented from shifting.
[0028] Please see Figure 5The second positioning pin 12 is movably sleeved inside the through hole 9. Two sets of second positioning pins 12 pass through the interior of the second connecting plate 11 and the second positioning pin 12 in sequence. By installing the second positioning pin 12 inside the through hole 9, and at the same time extending the second positioning pin 12 into the interior of the mounting hole 8, that is, the second positioning pin 12 passes through the interior of the mounting hole 8 to install the interior of the first connecting plate 10 or the second connecting plate 11. That is, when the through hole 9 and the second connecting plate 11 are installed inside the first nut 1 and the second nut 2, the stability of the position is maintained, which improves the stability of the positioning during equipment welding.
[0029] Please see Figure 6 The side of the weld point 13 is kept flush with the side of the first nut 1. When the first nut 1 and the second nut 2 are installed in alignment, the weld points 13 installed on the sides of the first nut 1 and the second nut 2 are in a close fit. The weld points 13 are fixedly connected to the outside of the first nut 1 and the second nut 2. The weld points 13 extend outward, which means that when the first nut 1 or the second nut 2 is controlled to weld, the welding position is limited to maintain stability. The welding efficiency is improved by assisting the welding. At the same time, the side of the weld point 13 is kept parallel to the side of the first nut 1 and the second nut 2. When the first nut 1 is rotated by a wrench, the weld point 13 interferes with the use of the wrench.
[0030] Working principle: The two sets of nuts are welded together. In the first state, the first nut 1 and the second nut 2 are aligned and installed. A first connecting plate 10 and a second connecting plate 11 are installed inside the mounting holes 8 of the first nut 1 and the second nut 2. Simultaneously, a second positioning pin 12 is installed inside the through hole 9, passing through the interior of the first nut 1 and the second nut 2. The second positioning pin 12 drives the first connecting plate 10 and the second connecting plate 11 to confine the first nut 1 and the second nut 2 inside. A first positioning pin 7 is installed inside the transverse groove 6 to further define the position between the first nut 1 and the second nut 2. Meanwhile, the welding points 13 installed on the outside of the first nut 1 and the second nut 2 are aligned and installed, allowing welding to be performed at the connection point. In the second welding state, the first positioning pin 7 is removed, and either the first nut 1 or the second nut 2 is rotated, changing the angle of the first nut 1 and the second nut 2 while maintaining a stable position. Welding is then performed on the outside of the connection point between the first nut 1 and the second nut 2.
[0031] When welding the control nut installation area, the first nut 1 and the bolt 5 are fixed by mutual thread engagement. At the same time, the welding point 13 installed at the lower end of the first nut 1 contacts the installation area. That is, the welding point 13 can assist the first nut 1 in welding, so as to improve the stability of the equipment installation.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
