Specific embodiment
It is described in detail below in conjunction with embodiment of the attached drawing to technical solutions of the utility model.Following embodiment is only
For clearly illustrating the technical solution of the utility model, therefore it is only used as example, and it is originally practical to cannot be used as a limitation limitation
Novel protection scope.
It should be noted that unless otherwise indicated, technical term or scientific term used in this application should be this reality
The ordinary meaning understood with novel one of ordinary skill in the art.
As shown in Figure 1, present embodiments providing a kind of 5 locking nut of elastic slice, including nut body 1 and limit screw 2, institute
The inside circumference face for stating nut body 1 is equipped with along axial joint-cutting 4, and the part being cut open is made to form elastic slice 5, the joint-cutting
4 perforation nut bodies 1.Here the part and nut body that joint-cutting 4 is cut open after radial incision further along axial incision
1 is integrated, and does not need that elastic slice 5 is separately provided.
As shown in Fig. 2, the outer circumference face of the nut body 1 is equipped with the threaded hole 3 opposite with the elastic slice 5, and
Threaded hole 3 is connected to the joint-cutting 4.The limit screw 2 is adapted to the threaded hole 3, is spun on threaded rod by nut body 1
It is upper and limit screw 2 is screwed in threaded hole 3 hold out against elastic slice 5, so that elastic slice 5 be made to be pressed on the outer surface of threaded rod.Here
The outer surface of limit screw 2 be equipped with the external screw thread that be adapted to threaded hole 3, in order to facilitate in the screw-in threaded hole 3 of limit screw 2,
Limit screw 2 is equipped with interior hexagonal, is used cooperatively it conveniently with allen wrench.
Limit screw 2 is screwed in threaded hole 3 using allen wrench in the present embodiment, continues precession limit screw 2 simultaneously
Extrusion elastic 5 is held out against, makes elastic slice 5 that small elastic deformation occur, while elastic slice 5 is pressed on the outer surface of threaded rod again.One side
Small elastic deformation, which occurs, for face elastic slice 5 can prevent limit screw 2 from loosening, and another aspect elastic slice 5 is pressed on threaded rod
It is upper to prevent nut body 1 to loosen with threaded rod again.This equipment is applied into the high-speed rotating main shaft of work mechanism, screw rod
Etc. bearing etc. in rotary shafts, fixed part can be greatly reduced and loosened, positioning accuracy is improved.
