The invention relates to the technical field of sleeves, and discloses a novel knurling, overturning and riveting sleeve structure design. The design comprises a sleeve shell, knurling teeth, an overturning and riveting sleeve, an upper carrying plate and a lower carrying plate, wherein the sleeve shell is a hollow cylinder which penetrates up and down, the diameter of an outer ring of the sleeveshell is smaller than the upper aperture of a sectional material, the outer diameter of the knurling teeth is in interference with the lower aperture of the sectional material in the range of 0.2-0.5mm, the part, at the lower ends of the knurling teeth, of the overturning and riveting sleeve is an overturning and riveting part, the height of the overturning and riveting part is 0.5-2.0 mm, the outer diameter of the overturning and riveting part is 0.2-1.0 mm smaller than the lower aperture of the sectional material, the wall thickness of the overturning and riveting part is 0.5-2.0 mm, the knurling teeth and the overturning and riveting part are formed through cold heading, and the overturning and riveting position is formed through cold heading. The outer diameter of the knurling teeth and the lower aperture of the sectional material are in interference fit in size. The overturning and riveting structure wraps the lower end face of the sectional material through overturning and riveting to achieve the interlocking function, the push-out force is larger than or equal to 2 kN, an upper rotating block is clamped between the upper surface of a bearing groove and the upper surface ofa lower bearing block, a lower bearing plate is movably connected with an upper bearing plate, and the structure design has the advantages of being high in locking performance, capable of ensuring rotation prevention and the like.
Description
Technical field [0001] The invention relates to the technical field of sleeves, in particular to a novel knurled riveting sleeve structure design. Background technique [0002] Knurled sleeves are usually used to press into aluminum profiles to support spacers. They are mainly used in the assembly position of new energy automobile aluminum profiles and other parts. The inner hole can be threaded or not. The threaded follow-up and bolt Fastened connection, without internal thread, only serves as a support spacer. Summary of the invention [0003] (1) Technical problems solved [0004] In view of the shortcomings of the prior art, the present invention provides a new type of knurled riveting sleeve structure design, which has the advantages of high locking performance and guaranteed anti-rotation, and solves the problem of not having high locking performance and not ensuring anti-rotation. . [0005] (2) Technical solution [0006] In order to achieve the above-mentioned high locking ...
