Abstract
The utility model discloses a kind of centering bolt, this centering bolt is by bolt shank, special pad, special nut, paniculidine lamination, taper spring sheet and nut composition, bolt shank is the cylindrical screw rod that two diameter is different, special nut both ends of the surface require vertical with its thread center's line, paniculidine lamination is circular cone thin-walled shape, cone shaped spring sheet is circular cone thin-walled bar rib shape, its cone angle is slightly larger than the cone angle of paniculidine lamination, the top of paniculidine lamination and taper spring sheet is small circular plane, its center all has circular hole, paniculidine lamination and taper spring sheet stack and are located on bolt shank microcephaly screw rod by circle hole sleeve on it, nut is arranged on bolt shank microcephaly screw rod and compresses taper spring sheet and paniculidine lamination.When time application of the present utility model solves some, bolt is connected and fixed, bolt and link surface off plumb problem, improve the quality of fit that bolt is connected and fixed installation.
Description
Technical field
The utility model relates to aircraft manufacturing process equipment technology field, especially relates to a kind of centering bolt.
Background technique
It is that fastening piece connects the most general method that bolt connects, plain bolt is when with being connected and fixed of link, due to out-of-flatness or crooked around screw outside a variety of causes in fact sometimes link, and plain bolt inner portion is a plane, cause bolt and link surface out of plumb when being connected and fixed, nut and pad can not be fitted with link intimate surface, do not reach the requirement of installing quality of fit.
Summary of the invention
Goal of the invention: the utility model provides a kind of centering bolt, bolt off plumb problem surperficial with link when plain bolt is connected and fixed when solving some.
Invention technological scheme: a kind of centering bolt, by bolt shank, special pad, special nut, paniculidine lamination, taper spring sheet and nut composition, be fixedly connected with the centering of link second for link first, it is characterized in that: described bolt shank is the cylindrical screw rod that two diameter is different, described special pad both ends of the surface require parallel, described special nut both ends of the surface require vertical with its thread center's line, described paniculidine lamination is circular cone thin-walled shape, described cone shaped spring sheet is circular cone thin-walled bar rib shape, its cone angle is slightly larger than the cone angle of paniculidine lamination, the top of described paniculidine lamination and taper spring sheet is small circular plane, its center all has circular hole, described paniculidine lamination and taper spring sheet stack and are located on bolt shank microcephaly screw rod by circle hole sleeve on it, described nut is arranged on bolt shank microcephaly screw rod and compresses taper spring sheet and paniculidine lamination, elastic force by described taper spring sheet holds out against paniculidine lamination, its top small circular plane is close in the intermediate step of bolt shank.When described centering bolt is installed and used, its major part screw diameter requires the hole being slightly less than link, the major part screw rod of described centering threaded screw fasteners bar is passed the hole of link first and link second, circular cone centering face on described centering bolt circular cone centering piece is adjacent to the hole inner side edge of link first, described special pad is set in outer surface bolt shank major part screw rod being adjacent to connected piece second, described special nut is arranged on bolt shank major part screw rod, special nut is tightened in rotation makes its end face compress special pad and link first and link second, the clamping position of described paniculidine lamination is by the self-alignment of variation energy, namely adjustment bolt shank is vertical with link second surface automatically.
The beneficial effect of the invention: the utility model one centering bolt, bolt and link surface off plumb problem when when solving some, bolt is connected and fixed, improve the quality of fit that bolt is connected and fixed installation, there is stronger navigability, versatility, flexibility.
Accompanying drawing explanation
Fig. 1 is the mounting structure schematic diagram of the utility model centering bolt;
In figure: 1-bolt shank, the special pad of 2-, 3-special nut, 4-paniculidine lamination, 5-taper spring sheet, 6-nut, 7-link first, 8-link second.
Embodiment
Below in conjunction with the drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of centering bolt, is made up of bolt shank 1, special pad 2, special nut 3, paniculidine lamination 4, taper spring sheet 5 and nut 6, is fixedly connected with link second 8 centering for link first 7.Described bolt shank 1 is the cylindrical screw rod that two diameter is different, described special pad 2 both ends of the surface require parallel, described special nut 3 biend requires vertical with its thread center's line, described paniculidine lamination 4 is circular cone thin-walled shape, its cone angle is 100 degree of-120 degree, described taper spring sheet 5 is circular cone thin-walled bar rib shape, its cone angle is slightly larger than the cone angle of paniculidine lamination 4, the top of described paniculidine lamination 4 and taper spring sheet 5 is small circular plane, its center all has circular hole, described paniculidine lamination 4 and taper spring sheet 5 stack and are located on bolt shank 1 microcephaly screw rod by circle hole sleeve on it, described nut 6 is arranged on bolt shank 1 microcephaly screw rod and compresses taper spring sheet 5 and paniculidine lamination 4, elastic force by described taper spring sheet 5 holds out against paniculidine lamination 4, its top small circular plane is close in the intermediate step of bolt shank 1.When described centering bolt is installed and used, the diameter at butt end of described bolt shank 1 requires the hole being slightly less than link, the bolt shank 1 major part screw rod of described centering bolt is passed the hole of link first 7 and link second 8, circular cone centering face in described paniculidine lamination 4 is adjacent to inside the hole of link first 7, described special pad 2 is set in outer surface bolt shank 1 major part screw rod being adjacent to connected piece second 8, described special nut 3 is arranged on bolt shank 1 major part screw rod, special nut 3 is tightened in rotation makes its end face compress special pad 2 and link first 7 and link second 8, the clamping position of centering bolt circular cone centering piece 4 is by the self-alignment of variation energy, namely adjustment bolt shank 1 is vertical with link second 8 surface automatically.
