Description
Technical field
The invention belongs to technical fields of mechanical processing, are related to cold riveting and are fastenedly connected technology more particularly to a kind of short-tail staking
The application method of fastening kit, dismantling device and dismantling device.
Background technology
Short-tail pulling rivet bolt includes short-tail screw, matched lantern ring.The type production relies on profession
Cold formed part machine, Equipment for Heating Processing, by dedicated molding die, control of product quality is stablized, can be realized efficient, automatic
The batch production of change.At present, the domestic high-end technical field that is fastenedly connected is increasing to the type product demand；With domestic public
Department is constantly explored, and has gradually grasped design principle, the technology of the type product.
Short-tail pulling rivet bolt of the present invention, which is mainly used in, substitutes bolt connection welding structure of high strength component etc.
Application scenario.Existing short-tail pulling rivet bolt mainly has two kinds of structures of Duola's slot and single kerve according to its short-tail design feature.
As shown in Figure 12, Figure 13, Figure 14, Duola's slot short-tail is mainly characterized by：
Spiral locking section 6.1 is made of complex-shaped curve, as in figure Duola's slot circular arc R 1, R2, R3 and R4 be with phase
The transient mode composition special construction cut；The class formation is higher to mold design, the requirement made, while is also unfavorable for product
Forming Quality inspection during mass production, so the type product cost is higher always；
Duola's slot 6.2 is made of four raised ring tooth 6.2.1 and groove 6.2.2, tooth top, tooth root with the ring tooth
The pulling claw of cooperation is also Duola's slot structure；To ensure that installation process smoothly completes, the keys such as the making precision of the two, form error
Element must the good occlusion that just can guarantee the two accurate enough.Meanwhile multiple-grooved short-tail structure must protect during installation
It demonstrate,proves the multiple-grooved pulling claw coordinated with it to be fully engaged against, is otherwise easy to cause load centralization on a small number of kerves, easily causes kerve and hold
The load received is excessive and there is a situation where kerve damage, iron filings block pulling claw.
As shown in figure 15, single kerve short-tail is mainly characterized by：
The list kerve by three sections of circular arcs r1, r2 and r3 successively it is tangent form it is complex-curved.Such short-tail structure is set
Meter there are it is certain the defects of, i.e. the shear behavior of short-tail is insufficient, tensile strength is bigger.And the structure exists during installation
Under the action of bearing axial load, cutting performance is shown as.Therefore pulling claw and single slot interocclusal clearance are susceptible in installation process
It is excessive to lead to stress concentration, it increases rapidly so as to the shear stress of short-tail structure and the shear fails of kerve is caused to be destroyed.It is another
Aspect, the curved surface composition of single kerve is complicated, and mold, mechanical processing are difficult, and Forming Quality detection efficiency is low.
Invention content
In order to solve the above technical problems, the invention discloses a kind of short-tail staking fastening kit, dismantling device and dismounting
The application method of tool, will its purpose is to solve positioning accuracy in existing short-tail pulling rivet bolt installation process, positioning method
The problem of asking height, kerve and be buckled poor processing difficulties, short-tail clamping force, stress concentration, low buckle service life, so as to meet
The basic demand of short-tail pulling rivet bolt Fast Installation, precise positioning improves bolt short-tail structure and the reliability and stabilization of buckle
Property.
In order to realize more than technique effect, the technical solution adopted by the present invention is：
A kind of short-tail staking fastening kit, the lantern ring including pulling rivet bolt, with pulling rivet bolt cooperation；The pulling rivet bolt packet
Ailhead and screw rod are included, the screw rod includes sequentially connected smooth section, thread segment and short-tail；Lantern ring includes flange pedestal and set
