Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described, but not as limiting to the invention.
Fig. 4 is the schematic diagram of a kind of blind nut Special riveting head of the present invention, and Fig. 5 is the schematic diagram of another angle of a kind of blind nut Special riveting head of the present invention, and Fig. 6 is the explosive view of a kind of blind nut Special riveting head of the present invention, refers to shown in Fig. 4 to Fig. 6. A kind of blind nut Special riveting head of the present invention, including a screw rod 4, one end of this screw rod 4, for being connected with external threads of rivet, carries out the external rivet of staking with this by screw rod 4. One positioning sleeve 5, this positioning sleeve 5 fixed cover is located at the middle part of screw rod 4. One nut check set 6, this nut check set 6 other end of connecting external screw relative to screw rod 4 is threaded. Overlap 6 control screw rods 4 by nut check rotate forward or reverse, connect with this or exit external screw. Meanwhile, nut check set 6 is close to each other with positioning sleeve 5. Also including a plane bearing 7, this plane bearing 7 is set on screw rod 4, and plane bearing 7 overlaps between 6 and positioning sleeve 5 in nut check, frictional force when reducing nut check set 6 rotation with this, positioning sleeve 5 caused. Being connected with external hand riveter by the riveted joint of the present invention, when screw rod 4 and external rivet interlacement staking, screw rod 4 does not turn, and turns after forcing screw rod 4 with this; After the screw rod 4 external rivet of staking completes, screw rod 4 reverses to exit. Meanwhile, screw rod 4 friction is driven to produce transfer when being prevented from nut check set 6 rotation by positioning sleeve 5.
The present invention also has following embodiment on the basis of the above:
In further embodiment of the present invention, continuing with referring to shown in Fig. 4 to Fig. 6. Both ends of the surface at plane bearing 7 are also close to respectively and are provided with a bearing guiding 71, and this two bearings guiding 71 is together set on screw rod 4 together with plane bearing 7, and two bearings guiding 71 is overlapped between 6 and positioning sleeve 5 in nut check together with plane bearing 7.
In further embodiment of the present invention, also having a cushion block 8 between plane bearing 7 and nut check set 6, this cushion block 8 is set on screw rod 4 so that can protect plane bearing 7 during nut check set 6 rotation, and be conveniently replaceable.
In further embodiment of the present invention, the end face that nut check set 6 deviates from cushion block 8 is provided with a screw 9. After screw rod 4 is connected with nut check set 6, screw 9 runs through nut check set 6 threadeds with screw rod 4.
In further embodiment of the present invention, being additionally provided with a catch 10 between nut check set 6 and screw 9, screw 9 is threadeded with screw 4 after extending through catch 10 and nut check set 6. When screw rod 4 completes the staking of external rivet, nut check set 6 retreats after encountering catch 10 backward so that screw rod 4 can exit external rivet.
In further embodiment of the present invention, the two ends of screw rod 4 are flank 41 and 42, and screw rod 4 flank 41 is connected with external rivet, and screw rod 4 flank 42 overlaps 6 with nut check and is connected.Screw rod 4 is shiny surface 43 except the middle part at flank 41 and 42 two ends, and positioning sleeve 5 is set on screw rod 4 shiny surface 43.
In further embodiment of the present invention, the opposite sides of screw rod 4 shiny surface 43 offers a keyway 44 respectively, the position being set in relative two keyways 44 of the positioning sleeve 5 outside screw rod 4 offers a screwed hole 51 respectively, and two screws 52 extend through two screwed holes 51 and are connected with two keyways 44.
In further embodiment of the present invention, screw rod 4 connects the diameter of flank 41 end of external rivet and is respectively smaller than the diameter of flank 42 end of screw rod 4 attaching nut's lock sleeve 6 and the diameter of screw rod 4 shiny surface 43 end.
In further embodiment of the present invention, a part for each keyway 44 is positioned at shiny surface 43 end in the middle part of screw rod 4 and is connected the edge of external threads of rivet face 41 end with screw rod 4 and forms an opening.
In the further embodiments of the present invention, the diameter of flank 42 end of screw rod 4 attaching nut's lock sleeve 6 is equal to the diameter of screw rod 4 shiny surface 43 end.
In sum, use one blind nut Special riveting head of the present invention, after riveted joint is mated with external hand riveter use, it is possible to effectively the rivet that nominal diameter is bigger is carried out staking by screw rod.
The foregoing is only preferred embodiment of the present invention; not thereby restriction embodiments of the present invention and protection domain; to those skilled in the art; the equivalent replacement done by all utilizations description of the present invention and diagramatic content and the obtained scheme of apparent change should be can appreciate that, all should be included in protection scope of the present invention.
