Description

Technical Field

[0001] This utility model relates to the field of nut installation technology, and in particular to a positioning device for a vertically riveted nut for vehicle lights. Background Technology

[0002] Riveting nuts are a type of fastener used in sheet metal and thin plates. They are also widely used in automotive lighting. They are made by pressing the riveting nut into a pre-drilled hole in the headlight housing using a riveting machine. This causes plastic deformation around the pre-drilled hole, which in turn fixes the riveting nut tightly to the headlight housing, thus forming an internal thread structure on the headlight housing that can effectively fix the screw.

[0003] Currently, the riveting of rivet nuts, especially vertically placed ones, is done manually, making it difficult to accurately place them into the pre-drilled holes. Furthermore, due to manual operation, it's challenging to effectively align the rivet nuts with the pre-drilled holes in the headlight housing, leading to unstable connections, deformation, and tilting, resulting in low work efficiency and reduced assembly quality.

[0004] Therefore, there is a need in the field for a device that can ensure the accurate alignment of the vertical rivet nut with the pre-drilled hole, accurately guarantee the pressing position, ensure assembly quality, and improve production efficiency. Utility Model Content

It can ensure that the vertical rivet nut is accurately positioned with the pre-drilled hole in the headlight housing, accurately ensure the pressing position, ensure assembly quality, and improve production efficiency.

[0006] To achieve the above objectives, this utility model provides the following solution:

[0007] This utility model provides a positioning device for a vertically rivetized nut for a vehicle lamp, including a rivet head, a magnet, a fastener, and a vertically placed rivet nut. The cylindrical end of the outer surface of the rivet nut is used to abut against the vehicle lamp housing. A nut profile is fixedly connected to the center of the lower end of the rivet head. The nut profile is used to rivet the rivet nut onto the vehicle lamp housing. An axial groove is formed along the axial direction at the lower end of the rivet head. The inner wall of the axial groove near the axis of the rivet head is adjacent to the outer surface of the nut profile. A transverse groove is provided on the outer surface of the lower end of the rivet head. The transverse groove communicates with the axial groove. The fastener can be inserted into the transverse groove. One end of the magnet is fixedly connected to the rivet head, and the other end of the magnet protrudes from the lower end face of the rivet head.

[0008] Preferably, two transverse grooves are provided.

[0009] Preferably, the nut is an internal hexagonal nut.

[0010] Preferably, the fastener is a set screw.

[0011] Preferably, the portion of the magnet protruding from the lower end face of the riveting head is a protrusion, the length of which is less than the sum of the vertical length of the riveting nut and the axial length of the nut profile, and greater than the axial length of the nut profile.

[0012] Preferably, the length of the protrusion is less than the sum of the vertical length of the rivet nut and the axial length of the nut profile, and greater than the axial length of the nut profile.

[0015] The present invention achieves the following beneficial technical effects compared to the prior art:

[0016] This utility model provides a positioning device for a vertically riveted nut for vehicle lights. The riveted nut is placed vertically, and its outer cylindrical end needs to abut against a pre-drilled hole in the vehicle light housing.

[0023] This utility model provides a nut press-in fixture, such as... Figure 1 As shown, the device includes a riveting head 1, a magnet 3, fasteners, and a vertically placed riveting nut 4. The column end of the outer surface of the riveting nut 4 abuts against the pre-drilled hole 6 of the headlight housing 5. A nut profile 7 is fixedly connected to the center of the lower end of the riveting head 1. The nut profile 7 matches the shape of the riveting nut 4 and is used to rivet the riveting nut 4 into the pre-drilled hole 6. An axial groove 8 is provided along the axial direction at the lower end of the riveting head 1. The inner wall of the axial groove 8 near the axis of the riveting head 1 is close to the outer surface of the nut profile 7. A transverse groove 9 is provided on the outer surface of the lower end of the riveting head 1.

One end of the magnet 3 is fixedly connected to the riveting head 1, and the other end of the magnet 3 protrudes from the lower end face of the riveting head 1.

[0024] Specifically, the rivet nut 4 is an internal hexagonal nut. The post end of the rivet nut 4 abuts against the bottom surface of the pre-drilled hole 6 of the headlight housing 5. Therefore, the magnet 3 is fixed on the rivet head 1 by fasteners, and the magnet 3 protrudes from the nut profile 7. The rivet nut 4 can be vertically attracted to the side of the magnet 3, that is, the rivet nut 4 is positioned in the vertical direction. Then, the rivet nut 4 is riveted into the pre-drilled hole 6 of the headlight housing 5 by the rivet head 1.

[0027] In this embodiment, the portion of the magnet 3 protruding from the lower end face of the riveting head 1 is a protrusion. The length of the protrusion is less than the sum of the vertical length of the riveting nut 4 and the axial length of the nut guide 7, but greater than the axial length of the nut guide 7. By limiting the length of the protrusion within this range, the riveting nut 4 can be attracted to the side of the magnet 3, ensuring the vertical positioning of the riveting nut 4.

[0028] In this embodiment, the shape of the nut profile 7 matches the shape of the riveting nut 4, thereby realizing the riveting effect on the riveting nut.

[0029] In this embodiment, the transverse groove 9 and the axial groove 8 are perpendicular to each other, making the installation of the magnet 3 more secure.
