Abstract
The utility model discloses a novel riveting bolt which comprises a threaded rod, a riveting rod and a riveting head. The riveting bolt is a toothed riveting bolt. The attaching surface between the riveting head and a riveting piece is of a toothed structure. The riveting rod is of a polished rod structure. According to the novel riveting bolt, the unique attaching surface of the toothed structure is adopted, so that riveting deformation is small; since the attaching surface of the toothed structure is inlaid in the end face of a front shell, even if riveting is not firm, the end face can be sealed secondarily and the sealing is more reliable when tightening force is applied to the front shell after products are in butt joint and the front shell is locked through a nut; in the riveting process, the forming effect is good, the products are slightly squeezed and deformed, radial deformation hardly exists, and the planeness of the front shell is good; when the distance between bolt holes is short, riveting is hardly influenced ; no harmful effect on the static strength of the front shell is caused.
Description
Technical field
The utility model relates to a kind of link of automobile-used parts, particularly a kind of novel riveted joint bolt of the riveted joint of the fore shell riveted part for vacuum booster.
Background technique
The fore shell riveted part of vacuum booster is to be formed by fore shell and two riveted joint bolt riveted joints, riveted joint bolt is special bolt, comprise screw rod, riveted joint bar and riveted joint, its riveted joint bar of traditional riveted joint bolt is straight burr structural riveting bar, the riveted joint of riveted joint bolt forms a step round column structure with riveted joint bar, the ring plain that during riveted joint, the faying surface of step and riveting parts is step, the faying surface that is riveted joint bolt and riveting parts is anchor ring structure faying surface, and the fore shell riveted part of vacuum booster mainly reaches the effect of sealing by the interference fit of riveted joint straight burr and bolt hole.There is following shortcoming in this riveted joint bolt:
1. due to homogeneity of product relation, when straight burr diameter capping, when the diameter of bolt hole removes the limit, magnitude of interference is inhomogeneous at fore shell endoporus place, forms projection in riveted joint, thereby endoporus is deformed;
2. straight burr riveted joint amount of deformation is large, and fore shell end face, because extruding deforms, causes planeness poor;
3. in straight burr riveted joint bolt when riveted joint,, when fore shell bolt hole is apart to fore shell bore edges distance hour, easily cause marginal swell, and not only planeness is poor, and has a strong impact on the sealability of product.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of simple in structure, the novel riveted joint bolt that rivet performance is good, to overcome the existing above-mentioned deficiency of prior art.
The technological scheme that the utility model is taked is: a kind of novel riveted joint bolt, comprise screw rod, riveted joint bar and riveted joint, and described riveted joint bolt is tooth form riveted joint bolt, the faying surface of riveted joint and riveting parts is tooth form structure faying surface.
Its further technological scheme is: described riveted joint bar is polished rod structural riveting bar.
Owing to taking technique scheme, compared with traditional straight burr riveted joint bolt, the novel riveted joint bolt of the utility model has following beneficial effect:
1. the novel riveted joint bolt of the utility model adopts unique tooth form structure faying surface, riveted joint distortion is little, tooth form structure faying surface is embedded in fore shell end face, even in riveted joint insecure (the bad situation of durability), after product docking, after fore shell nut check, give its tightening force, secondary guarantees end face seal, and sealing is more reliable;
2. riveted joint process forming, in riveted joint process product extrusion little, substantially without radial deformation, fore shell planeness is good;
When bolt hole edge to the distance of fore shell bore edges hour, tooth form sealing still can keep good planeness and sealing, can more easily adapt to the variation of product, bolt hole apart from less on riveting substantially without affecting;
4. tooth form sealing, to fore shell aperture to not pushing, has no adverse effects to the static strength of fore shell.
The technical characteristics of the novel riveted joint bolt below in conjunction with drawings and Examples to the utility model is further described.

Embodiment
A kind of novel riveted joint bolt, comprises screw rod, riveted joint bar and riveted joint, and described riveted joint bolt is tooth form riveted joint bolt 1, and the faying surface of described riveted joint and riveting parts is tooth form structure faying surface 131.
Described riveted joint bar is polished rod structural riveting bar 12.
Front shell assemblies installation step:
(front shell assemblies mainly comprises fore shell, fore shell stopping-off piece, fore shell riveted joint bolt)
1. stopping-off piece, fore shell are adjacent to, by novel riveted joint bolt inserting bolt hole;
2. the assembly upper step being assembled is placed on Special riveting equipment and rivets;
3. pair front shell assemblies of having riveted is carried out sealing propertytest, qualifiedly completes assembling.
Claims (2)
1. a novel riveted joint bolt, comprises screw rod, riveted joint bar and riveted joint, it is characterized in that: described riveted joint bolt is tooth form riveted joint bolt, and the faying surface of riveted joint and riveting parts is tooth form structure faying surface.
