Abstract
The invention belongs to rivet technology fields, it is related to clutch limiting rivet, there is annular stop boss in the central integration of solid cylinder, the annular stop boss is radially outward integrally formed with circular cylinder at the middle part of solid cylinder, the both ends of circular cylinder extend radially outwardly out annular convex shoulder, and advantage is：Light-weight, save material plastic deformation from rivet to the edge of the riveted holes of connected piece is uniform, is used suitable for doing the limiting rivet on clutch.
Description
Technical field
The invention belongs to rivet technology fields, refer in particular to a kind of clutch limiting rivet.
Background technology
At present, the structure of general clutch limiting rivet is：There is annular limit in the central integration of solid cylinder
Position boss, the both ends of clutch limiting rivet is respectively penetrated, riveted is carried out in the riveted holes for the connector for being limited connection, real
Existing /V connection, is disadvantageous in that：First, since the annular stop boss in the middle part of it is that outer diameter is more than solid cylinder
Circular cylinder, most of material in the middle part of the circular cylinder does not support, /V and connection function, really plays position-limiting action
Be circular cylinder both ends of the surface annular convex shoulder, as long as the outer diameter of the annular convex shoulder is sufficiently large, you can play position-limiting action, and
Diameter in the middle part of circular cylinder at all It is not necessary to do it is big as the outer diameter of the annular convex shoulder of circular cylinder both ends of the surface,
Because wasting raw material like that, and add the weight of product；Second is that the design at conventional rivets plastic deformation is not reasonable,
So that the plastic deformation of rivet is not uniform enough after riveting, the plastic deformation of some places is big, and the plastic deformation of some places is small, makes
Obtain unbalance stress.
The content of the invention
The object of the present invention is to provide a kind of light-weight, clutch limiting rivets for saving material.
The object of the present invention is achieved like this：
Clutch limiting rivet has annular stop boss in the central integration of solid cylinder, and the annular stop is convex
Platform be at the middle part of solid cylinder radially outward integrally formed with circular cylinder, the both ends of circular cylinder radially to
Extend annular convex shoulder outside.
The both ends of above-mentioned solid cylinder are both provided with necking down.
The both ends of the surface of above-mentioned solid cylinder are both provided with the bowl-type pit to concave.
Above-mentioned clutch limiting rivet is made of aluminium or aluminum alloy materials.
The present invention compared with prior art protrude the advantages of be：
1st, it is light-weight, save material：Since the circular cylinder of the present invention together forms original cylinder with annular convex shoulder
The position-limiting action of body, the boss of annular convex shoulder and circular cylinder therein can play the role of /V, two convex annulars completely
The outer diameter of circular cylinder between shoulder is less than the outer diameter of annular convex shoulder, so that the weight of the present invention is compared with prior art
Light-weight, the weight of mitigation is the weight for the raw material saved；
2nd, the present invention sets bowl-type pit in the both ends of the surface of solid cylinder so that during riveting, the outer end of solid cylinder is just
It is equably plastically deformed in the edge of the riveted holes to connected piece and realizes riveting.
3rd, the present invention uses suitable for doing the limiting rivet on clutch.
Description of the drawings
Fig. 1 is the structure sectional view of the present invention；
Fig. 2 is the use state sectional view of the present invention.
Specific embodiment
With specific embodiment, the invention will be further described below, referring to Fig. 1：
Clutch limiting rivet has annular stop boss, the annular stop in the central integration of solid cylinder 10
Boss is radially outward integrally formed with circular cylinder 20, the both ends of circular cylinder 20 at the middle part of solid cylinder 10
Extend radially outwardly out annular convex shoulder 30, the outer diameter D 1 of the 2 ＞ solid cylinders 10 of outer diameter D of circular cylinder 20.
The both ends of above-mentioned solid cylinder 10 are both provided with necking down 101.
The both ends of the surface of above-mentioned solid cylinder 10 are both provided with the bowl-type pit 40 to concave.
Above-mentioned clutch limiting rivet is made of aluminium or aluminum alloy materials.
The application of the present invention, referring to Fig. 2：
In the riveted holes that the left and right both ends of clutch limiting rivet 1 are respectively penetrated to the connector 2,3 for being limited connection, then
Riveted connection is carried out with riveting gun, 10 stress of solid cylinder of 20 both sides of circular cylinder is plastically deformed, seeks connections in quilt
The edge of the riveted holes of connector 2,3 is able to riveting, recessed due to being provided with bowl-type in the both ends of the surface of solid cylinder 10
Hole 40 so that during riveting, the edge equably plasticity change of the riveted holes to connected piece is convenient in the outer end of solid cylinder 10
Shape and realize riveting.
Above-described embodiment is only one of presently preferred embodiments of the present invention, is not limited the scope of the invention according to this, therefore：
The equivalence changes that all structures under this invention, shape, principle are done, should all be covered by within protection scope of the present invention.
