Description

Technical Field

[0001] The utility model relates to the technical field of riveting, in particular to a novel stud riveting structure. Background Art

[0002] Typically, when a general metal component needs to be mounted with a mounting plate for various objects or to be directly mounted with an object, the mounting plate or object needs to be fixed with screws in a threaded hole. If the metal component is drilled and tapped directly, it will not be firmly fixed with screws because the metal component is usually made of relatively thin metal sheets. Therefore, a stud with an internal thread on one end and a cylinder or hollow cylinder riveted on the other end are often used to fix the mounting plate or object to the metal component with screws. This riveting method is one of the commonly used connection and fixing methods. The usual practice is to first machine a hole in the metal structure, then insert a cylinder with an internal thread on one end and a diameter that matches the hole on the metal structure on the other end into the circular hole of the metal plate, and then use riveting to fix the stud to the metal component.

[0021] Reference Figures 1 to 5 A novel stud riveting structure includes a riveting piece 1 and a riveting stud 2 riveted with the riveting piece;

[0022] A convex 11 is provided at the installation position of the rivet stud corresponding to the rivet part; the convex 11 is to prevent the stud wall from protruding from the material surface;

[0023] A punching hole 12 is provided on the convex bulge, and the function of the punching hole is to punch the tooth;

[0024] Threads 13 are drawn at the corresponding positions of the punching holes, and bulges are formed around the punching holes to facilitate riveting and fixing with riveting studs;

[0025] The diameter of the punching hole 12 is smaller than the diameter of the convex hull;

[0026] The riveted stud 2 includes a stud body 21, a stud base 22 disposed at the bottom of the stud body, a bottom tooth portion 23 disposed outside the stud body and on the stud base, and a stud side tooth portion 24 disposed outside the stud body 21 and on the bottom tooth portion 23.

[0027] In order to enable the bottom teeth 23 to be pressed together with the rivet without affecting the product, the diameter of the bottom teeth 23 is larger than the stud body 21 and smaller than the stud bottom 22. The bottom teeth 23 fits in contact with the convex surface, and the punching holes 12 and the tooth extraction part are pressed into the bottom teeth 23 for fixation.

[0028] The stud side teeth are press-fitted with the teeth, and the stud side teeth are used to cooperate with the raised portion of the teeth for press-fitting. In order to ensure that the stud side teeth can effectively cooperate with the teeth for press-fitting, the diameter of the stud side teeth is larger than the diameter of the teeth. The diameter of the stud side teeth 24 is larger than the stud body 21 and smaller than the diameter of the bottom tooth portion 23. A gap 25 is left between the stud side teeth and the bottom tooth portion 23. This gap is used to press the teeth portion, thereby further ensuring the strength of the riveting;

[0029] The stud body 21 is provided with a through hole 26 , which is a water outlet for stud electroplating to prevent the stud from rusting due to electroplating liquid.

[0030] The diameter of the stud base 22 is larger than the diameter of the stud body 21, and the diameter of the stud base is larger than the diameter of the punched hole and smaller than the diameter of the bulge; and the thickness of the stud base is less than or equal to the height of the bulge; thereby ensuring that the stud base does not protrude from the surface of the riveted part after riveting, forming a bulge;

[0031] In this implementation case, the position where the stud is to be riveted is first convexed upwards. The convex bulge is to prevent the stud wall from protruding from the material surface. A hole is punched on the bulge. The purpose of the punching is to make threads on the surface. The threads are drawn at the position of the upper hole on the bulge. The threading height is about 3MM. The stud is riveted in the threading hole to complete the riveting.

[0032] The benefits of the present invention are that the present technical solution pre-processes the rivet parts to cooperate with the new riveting studs for riveting, and the rivets are provided with different bottom tooth parts and stud side tooth parts to cooperate with the rivet parts for pressing, and at the same time, a gap is left between the bottom tooth parts and the stud side tooth parts to ensure the flow of material, further increase the strength, and ensure the fixing effect.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
