Abstract
The utility model relates to a cup self-plugging rivet, comprising a rivet bar and a rivet body sleeved on the rivet bar. The rivet body and the rivet bar are round and columnar. A head part of the rivet bar is provided with a fracture port ring groove. The main characteristics are that the end of the rivet bar is provided with a rounded column body which is larger than the diameter of the rivet bar. A cylindrical hole sinking is arranged inside the rounded column and an opening surface rounded column of the hole sinking is provided with an outward turning edge. The rivet body is fixedly sleeved on the upper part of the rivet bar. The cup self-plugging rivet, during riveting, can make the rounded column body on the head part of the rivet bar locked closely inside the rivet body, having the functions of waterproof and earthquake resistance, increasing the tensile force and shear resistance of the riveted lap-splice joints.
Description
The utility model relates to a kind of self-plugging rivet, particularly relates to a kind of cup-shape self-plugging rivet.
In the connection of metal sheet, people have begun the extensive use self-plugging rivet and have connected fasteningly, and common self-plugging rivet possesses the blind riveting function, and is easy to operate.Retrieve through new patent searching, a kind of solid self-plugging rivet is promptly disclosed as patent 91230910.5, its major character be the solid self-plugging rivet shade that has mushroom shaped by head cylindrical shape rivet body and be fixed in the cylindrical hole of rivet body the end greater than the nail body of rod and formed by the rivet bar of the cylindrical shape of impression, after the riveted joint, rivet body and the rivet bar of staying in the rivet body hole are realized fastening connection to coupled simultaneously.The purpose of this patent improves the riveting parts mechanical strength by this structural design, and shearing resistance and stretching resistance.
But in the industry of specific (special) requirements, if vanning, the use on the passenger vehicle just exists shockproof properties poor, do not possess defectives such as water-proof function and clamping force are not strong, special in the riveted joint between the sheet metal with elasticity spacing, its insufficient clamping force is obvious especially.
The purpose of this utility model just provides and a kind ofly can strengthen the cup-shape self-plugging rivet that clamping force has waterproof, shockproof function again.
Realize that technical solution of the present utility model is: a kind of cup-shape self-plugging rivet, constitute by rivet bar and cover rivet body thereon, the rounded column of rivet body, the rounded column of rivet bar, head has rivet bar fracture port annular groove, and its major character is that the rivet bar end is the circular cylinder greater than the rivet bar diameter, and cylindrical counterbore is arranged in the circular cylinder, the limit of outside turnup is arranged on the actinal surface circular cylinder of counterbore, and rivet body is fixedly set in the top of rivet bar.
And the cylindrical body of rivet bar end can constitute for round platform and cylindrical body.
Therefore the utility model, has the following advantages owing to adopt technique scheme:
1. the end of rivet bar is the cylindrical body of diameter greater than rivet bar, the taper circular cylinder that cylindrical body can be constituted by round platform and circular cylinder, under the effect of staking, the rivet body diameter becomes coupled of big promotion and is affixed to coupling, clamped nail bar fracture, the taper circular cylinder of rivet bar head is locked in the rivet body, has strengthened stretching resistance, the shearing resistance of riveted joint coupling.
2. there is the counterbore of a cylindrical shape cylindrical inside, the end of rivet bar, the limit that outside turnup is arranged on the actinal surface circular cylinder of counterbore, the cup-shape self-plugging rivet is in the riveted joint process, rivet body deformation also makes the hole in the rivet body that plastic deformation takes place, the taper circular cylinder of rivet bar head is locked in the rivet body, thereby has played the effect of waterproof and antidetonation.
Fig. 1 is the structural representation of the utility model cup-shape self-plugging rivet.
Fig. 2 is the structural representation of the rivet body of the utility model cup-shape self-plugging rivet.
Fig. 3 is the structural representation of the rivet rod of the utility model cup-shape self-plugging rivet.
Fig. 4 is the working state schematic representation of the utility model cup-shape self-plugging rivet.
The utility model is described in further detail below in conjunction with accompanying drawing:
Rivet body 1, rivet bar 2, rivet body endoporus 101, rivet body shade 102, rivet bar groove 3, rivet bar end circular cylinder 4, rivet bar round platform 401, rivet bar cylindrical body 402, counterbore 5, flange 6.
Referring to Fig. 1,2,3,4, this cup-shape self-plugging rivet is made of rivet body 1 and rivet bar 2.Rivet body 1 rounded column, a termination portion shade 102 of the rivet body 1 of circular cylindrical shape is mushroom shaped, and the cylindrical hole 101 of a stepped shaft is arranged in the circular cylindrical shape rivet body 1, and matching with the top of rivet bar 2 in the hole, forms through pressing to be fixedly connected.
Rivet bar 2 is cylindrical metallic rod, the end of rivet bar 2 is cylindrical bodys 4, the diameter of rivet bar end cylindrical body 4 is bigger than the diameter of rivet bar 2, the assemblying body that end cylindrical body 4 can be made by round platform 401 and cylindrical body 402 constitutes tapered cylinder head 4, the counterbore 5 that a cylindrical shape is arranged in the inside of this cylindrical body 4, the limit 6 that outside turnup is arranged on the actinal surface circular cylinder of counterbore 5, this assemblying body such as cup-shape like this, there are this head assemblying body and the linkage section of nail bar that the annular groove 3 etc. of transition size and protruding endless belt and depression is arranged, groove 3 is the point of rupture of rivet bar, afterbody at rivet bar has many more shallow annular grooves, anti-skidding design when this annular groove is staking.
The cup-shape self-plugging rivet is when work, the cup-shape self-plugging rivet is put into the hole that adapts with the rivet body diameter on the coupling, connected piece allows certain clearance, often run in practical operation, must be in the rivet body length dimension less than this gap, so just do not need manually to make them to be adjacent to and execute riveted joint again, this is one of characteristics of cup-shape self-plugging rivet, then, again the afterbody of rivet bar is put in the muzzle of riveting gun, under the effect of staking, the rivet bar motion, the cup type assemblying body of rivet bar head expands rivet body gradually, coupled of the big promotion of rivet body diameter change is affixed to coupling like this, last clamped nail bar fracture, and in the actual riveted joint process, the rivet body distortion also makes the hole in the rivet body that plastic deformation takes place, be extruded on the rivet bar in the size section, thereby make the cup type body of rivet bar head and rivet body connection as a whole, so just realized high-clamping force, waterproof, shockproof function.
