Description

Technical Field

[0001] The utility model relates to the technical field of nuts, in particular to a hexagonal welding nut with a positioning function. Background Art

[0002] Hexagonal weld nuts are hexagonal nuts used for welding. They have a hexagonal shape, with one side similar to a hexagonal nut and the other side having three weld points and a boss. The three weld points are used for welding, and the boss is used for positioning.

[0003] Hexagonal weld nuts solve the problem of conventional nuts failing to secure the base. One side of the nut features three weld points and a circular boss. The boss is used for positioning, while the weld point is used for welding. First, a positioning hole is punched into the base, and the nut's boss is positioned over the hole. Then, a spot welder is used to weld the nut to the base. The welding process involves melting the three weld points at high temperatures, causing them to fuse to the base, achieving the desired connection. This type of connection is considered a non-detachable connection.

[0004] Existing Chinese patent publication number CN218408098U discloses a hexagonal weld nut with a positioning function, comprising a hexagonal body, a transition groove within the hexagonal body, a groove within the transition groove, a threaded ring at the center of the bottom end of the groove, a nut rim at the bottom end of the hexagonal body, an alignment structure at the bottom end of the threaded rim, and a weld spot on one side of the alignment structure. Beneficial effects: The weld nut structure provided by this utility model improves the firmness of the connection between the nut and the welded matrix, while also maintaining horizontal balance between the nut and the welded matrix during automatic spot welding, preventing positional offset when the bolt and the welded nut are docked.

[0005] However, the hexagonal welding nut with positioning function still has some shortcomings in actual use. For example, it is not possible to quickly align the welding point with the welding matrix conveniently. At the same time, during the welding process, there is a lack of necessary limiting devices. Although the nut and the welding matrix can maintain horizontal balance during the automatic spot welding process, it cannot prevent the nut from rotating horizontally, resulting in a mediocre welding effect at the welding point and insufficient stability. Utility Model Content

[0006] The purpose of the utility model is to provide a hexagonal welding nut with a positioning function to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a hexagonal weld nut with a positioning function, comprising a weld nut assembly, a welding positioning assembly being fixedly mounted on the bottom surface of the weld nut assembly, the weld nut assembly comprising a weld nut body, the top and bottom surfaces of the weld nut body being hexagonal in shape;

[0008] The welding positioning assembly includes a positioning boss, which is arranged in a circular ring shape. A ring-shaped magnetic patch is fixedly installed on the bottom surface of the positioning boss. Three embedded circular grooves are provided on the bottom surface of the positioning boss. A No. 1 magnetic block is fixedly installed on the top surface of the three embedded circular grooves. A No. 2 magnetic block is slidably installed in the three embedded circular grooves. Positioning pins are fixedly installed on the bottom surfaces of the three No. 2 magnetic blocks.

[0009] Preferably, the positioning boss is fixedly mounted on the bottom surface of the welding nut body.

[0010] Preferably, the outer ring of the welding nut body is provided with a rounded corner, and the rounded corner is polished.

[0011] Preferably, welding points are provided at the three corners of the bottom surface of the welding nut body, and the protruding heights of the welding points are the same.

[0012] Preferably, a threaded docking hole is provided at the center of the bottom surface of the welding nut body, and the center of the top surface of the positioning boss and the center of the bottom surface of the threaded docking hole are on the same vertical line.

[0013] Preferably, the three No. 1 magnetic blocks correspond to the three No. 2 magnetic blocks in one-to-one correspondence, and the No. 1 magnetic blocks and the No. 2 magnetic blocks are arranged opposite to each other with the same polarity and mutually exclusive.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The hexagonal welding nut with a positioning function is achieved by inserting the positioning boss into the annular groove provided on the surface of the welding matrix and manually rotating the welding nut body. During the rotation process, each positioning pin also rotates to the positioning hole. Then, the positioning pin pops out from the embedded circular groove and enters the positioning hole under the mutual repulsion of the No. 1 magnetic block and the No. 2 magnetic block. At this time, the welding point is exactly docked with the welding point on the welding matrix, thereby achieving a rapid positioning effect. In addition, during the welding process, the three positioning pins are inserted into the corresponding positioning holes to play a stabilizing role, avoiding rotation and displacement of the welding nut body during welding, thereby improving welding efficiency and quality.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-4 As shown, the utility model provides a technical solution: comprising a welding nut assembly 1, a welding positioning assembly 2 is fixedly installed on the bottom surface of the welding nut assembly 1, the welding nut assembly 1 comprises a welding nut body 101, and the top and bottom surfaces of the welding nut body 101 are hexagonal;

[0023] The welding positioning assembly 2 includes a positioning boss 201, which is arranged in a circular ring shape. The bottom surface of the positioning boss 201 is fixedly installed with an annular magnet 202, and the bottom surface of the annular magnet 202 is provided with a circular opening corresponding to the positioning pin 206. The annular magnet 202 is adsorbed with the bottom surface of the annular groove, and the bottom surface of the annular groove is made of iron material, which can improve the docking stability of the nut. The bottom surface of the positioning boss 201 is provided with three embedded smooth circular grooves 203, and the top surfaces of the three embedded smooth circular grooves 203 are fixedly installed with a No. 1 magnetic block 204, and the three embedded smooth circular grooves 203 are slidably installed with a No. 2 magnetic block 205. The bottom surfaces of the three No. 2 magnetic blocks 205 are fixedly installed with a positioning pin 206.

[0024] In this embodiment, the positioning boss 201 is fixedly mounted on the bottom surface of the welding nut body 101. The outer ring of the welding nut body 101 is provided with rounded corners, and the rounded corners are polished. Welding points 102 are provided at the three corners of the bottom surface of the welding nut body 101. The protruding height of the welding points 102 is the same. The three welding points are used for welding, and the boss is used for positioning.

[0025] A threaded docking hole 103 is provided at the center of the bottom surface of the welding nut body 101, and the center of the top surface of the positioning boss 201 and the center of the bottom surface of the threaded docking hole 103 are on the same vertical line.

[0026] The three No. 1 magnetic blocks 204 and the three No. 2 magnetic blocks 205 correspond one to one. The No. 1 magnetic block 204 and the No. 2 magnetic block 205 are arranged opposite each other with the same polarity and mutually repel each other. Under the mutual repulsion of the No. 1 magnetic block 204 and the No. 2 magnetic block 205, they pop out from the embedded smooth circular groove 203 and enter the positioning hole. At this time, the welding point 102 is just docked with the welding point on the welding mother body, thereby achieving a rapid positioning effect.

[0027] When in use, it is only necessary to align the positioning boss 201 provided on the bottom surface of the welding nut body 101 with the corresponding annular groove provided on the welding matrix. A positioning hole corresponding to the positioning pin 206 is provided in the annular groove. After alignment, the positioning boss 201 is inserted into the annular groove so that the annular magnetic patch 202 fixedly installed on the bottom surface of the positioning boss 201 contacts the bottom surface of the annular groove. During the insertion process of the positioning boss 201, the positioning pin 206 will be pressed into the embedded smooth circular groove 203. Then, the welding nut body 101 is manually rotated. During the rotation process, when the welding nut body 10 After the welding point 102 set on the bottom surface of 1 is rotated to the welding position, at this time, each positioning pin 206 is also rotated to the positioning hole, and then the positioning pin 206 will pop out from the embedded smooth circular groove 203 and enter the positioning hole under the mutual repulsion of the first magnetic block 204 and the second magnetic block 205. At this time, the welding point 102 is just docked with the welding position on the welding mother body, thereby achieving a rapid positioning effect, and during the welding process, the three positioning pins 206 are inserted into the corresponding positioning holes to play a stabilizing role, avoiding rotation and displacement of the welding nut body 101 during the welding process.

[0028] To sum up, the hexagonal welding nut with positioning function is achieved by inserting the positioning boss 201 into the annular groove opened on the surface of the welding mother body and manually rotating the welding nut body 101. During the rotation process, each positioning pin 206 also rotates to the positioning hole. Then, the positioning pin 206 will pop out from the embedded circular groove 203 and enter the positioning hole under the mutual repulsion of the No. 1 magnetic block 204 and the No. 2 magnetic block 205. At this time, the welding point 102 is just docked with the welding point on the welding mother body, thereby achieving a rapid positioning effect. In addition, during the welding process, the three positioning pins 206 are inserted into the corresponding positioning holes to play a stabilizing role, thereby avoiding rotation and displacement of the welding nut body 101 during welding, thereby improving welding efficiency and quality.
