Abstract
The invention discloses a rivet for a ribbon retainer. The rivet comprises a rivet head and a rivet rod; the upper end of the rivet head is a plane; the rivet rod comprises a tight rod and a loose rod; the tight rod is connected with the rivet head; the tight rod and the loose rod are in a two-step shape; the diameter of the tight rod is greater than the diameter of the loose rod; a transitional guide angle is arranged between the tight rod and the loose rod; the tail end of the loose rod is provided with a tail cone with a chamfer; the tight rod is in interference fit with a ribbon retainer hole; the length of the tight rod is equal to the plate thickness of the ribbon retainer. The rivet is in interference fit with the ribbon retainer hole and can be effectively prevented from falling off; as the upper end of the rivet head is the plane, the perpendicularity of the rivet in a rivet die can be ensured, the riveting quality is good, and poor conditions of riveting slanting, riveting deflection and rivet lacking are basically eliminated.
Description
Technical field
The present invention relates to a kind of rivet arrangement, refer in particular to the ribbon retainer rivet that a kind of riveted is effective, manufacturing efficiency is high.
Background technique
Deep groove ball bearing is made up of ribbon retainer, rolling element, inner ring and outer ring.Ribbon retainer through riveted, will make two halves retainer rivet securely and plays maintenance effect when assembling.Prior art is when assembling bearing, and need to be dialled by ball even after dress ball, buckle two halves retainer, then inserted one by one in the rivet hole of retainer by rivet, button upper rivet model, deliver to punching press in punch press, efficiency is low.The rivet arrangement of prior art as shown in Figure 1, is made up of rivet head and rivet bar two-part.Ribbon retainer rivet hole coordinates with rivet sizes and adopts Spielpassung, in binding process, monolithic ribbon retainer loads onto rivet, owing to there is gap between ribbon retainer rivet hole and rivet, due to excesssive gap after rivet loading retainer, rivet can move up, rivet easily comes off, frequent generation lacks nail phenomenon, patch is cumbersome, particularly after riveted, bearing must be carried out tearing cover process open, not only waste of manpower, material resources, also easily damage the finished product accuracy of bearing inner race, outer ring, steel ball.In process of production, often generation riveting is askew, riveting inclined and lack nail phenomenon, affects manufacturing efficiency and the quality of product of bearing.Therefore be necessary to improve rivet, solve that riveting is askew, riveting partially and lack the problems such as nail, raising assembly quality and end product quality.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: propose the ribbon retainer rivet that a kind of riveted is effective, manufacturing efficiency is high.
Technical solution of the present invention is achieved in that: a kind of ribbon retainer rivet, comprises rivet head and rivet bar; The upper end of described rivet head is plane; Described rivet bar comprises tight bar and loose bar; Described tight bar is connected with rivet head; Described tight bar and loose bar are secondary stairstepping; Described tight shank diameter is greater than loose shank diameter; Transition angle of deflection is provided with between described tight bar and loose bar; The tail end of described loose bar is also provided with the tail bone of band chamfering.
Preferably, described tight bar and ribbon retainer rivet hole form interference fit.
Preferably, the length of described tight bar is equal with ribbon retainer thickness of slab.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Ribbon retainer rivet of the present invention, interference fit is adopted with ribbon retainer hole, can effectively prevent rivet from coming off, the upper end planar design of rivet head, can ensure the perpendicularity of rivet in riveting mould, riveting quality is good, riveting is askew, riveting is inclined and lack the unfavorable conditions such as nail eliminates substantially, because this reducing waste product, save cost, and effectively improve bearing products quality and assembling manufacturing efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of the bookbinding ribbon retainer rivet of prior art;
Accompanying drawing 2 is the structural representation of bookbinding ribbon retainer rivet of the present invention;
Accompanying drawing 3 is bookbinding ribbon retainer rivet of the present invention and ribbon retainer structural representation when assembling;
Wherein: 1, rivet head; 2, rivet bar; 3, tight bar; 4, loose bar; 5, transition angle of deflection; 6, tail bone; 7, ribbon retainer.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Ribbon retainer rivet arrangement of the present invention as shown in Figure 2, comprises rivet head 1 and rivet bar 2; The upper end of described rivet head 1 is plane, ensure that the perpendicularity of rivet in riveting mould; Described rivet bar 2 comprises tight bar 3 and loose bar 4; Described tight bar 3 is connected with rivet head 1; Described tight bar 3 and loose bar 4 are in secondary stairstepping; Described tight bar 3 diameter is greater than loose bar 4 diameter; Transition angle of deflection 5 is provided with between described tight bar 3 and loose bar 4; The tail end of described loose bar 4 is also provided with the tail bone 6 of band chamfering, tail bone 6 to slotting riveting and trap very favourable.
Further instruction, described tight bar 3 forms interference fit with ribbon retainer 7 rivet hole, can effectively prevent rivet from coming off.
Further instruction, the length of described tight bar 3 is equal with ribbon retainer 7 thickness of slab.
Ribbon retainer rivet of the present invention, interference fit is adopted with ribbon retainer hole, can effectively prevent rivet from coming off, the upper end planar design of rivet head, can ensure the perpendicularity of rivet in riveting mould, riveting quality is good, riveting is askew, riveting is inclined and lack the unfavorable conditions such as nail eliminates substantially, because this reducing waste product, save cost, and effectively improve bearing products quality and assembling manufacturing efficiency.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
