Promote riveting first-time qualification rate, it is to avoid spiral lock cylinder cracking and structural member are impaired.Use cam mechanism and the most spacing,
Rivet rod 5 cone punch stroke and riveting degree controlled under ensure that the concordance of riveting quality, overcome spiral lock cylinder non-round
Problem.
Accompanying drawing explanation
In order to be more clearly understood that the present invention, now implement to describe the present invention referring concurrently to accompanying drawing by the present invention, its
In: Fig. 1 is that structural representation cuts open in the office of spiral lock riveting tool.
In Fig. 1: 1 depression bar, 2 handles, 3 arch clamps, 4 lobe plates, 5 rivet rods, 6 studs, 7 back-up rings, 8 snap rings, 9 pressure rings, 10
Spring, 11 springs, 12 nuts, 13-15 straight pin.
Describe the detailed description of the invention of the present invention a kind of spiral lock riveting tool below in conjunction with the accompanying drawings in detail.
Detailed description of the invention
Refering to Fig. 1.In embodiment described below, spiral lock riveting tool uses eccentric cam mechanism height kinematic pair former
Reason, lobe plate 4 contour curve is by circular arc and rectilinear(-al).The two ends armstand of arch clamp 3 is formed respectively with through armstand
Rivet rod 5 and coaxial line point to the stud 6 of described rivet rod 5；Stud 6 external diameter is less than spiral more than the external diameter of spiral lock, rivet rod 5 external diameter
Being shaped with the cone drift identical with spiral lock installing plate counterbore angle on lock cylinder body diameter and end, rivet rod 5 is by described armstand
Cross through hole, through the thrust spring 11 of described cone drift backside assembling and rebound spring 10 be connected to depression bar 1 convex
Wheel plate 4, wherein, thrust spring and rebound spring are respectively by the snap ring 8 being positioned in rivet rod 5 draw-in groove and described armstand cross through hole
Port isolation retrains；Rivet rod 5 is provided thrust by thrust spring 11, rebound spring 10 provide resilience driving force；Snap ring 8 is rivet rod
5 provide rebound stroke spacing.Pressure ring 9 utilizes back-up ring 7 spacing, and is provided thrust by spring 11, and in riveting process, pressure ring 9 is close to
Spiral lock installing plate, provides insulation blocking for rivet rod 5 end vertebral body drift and spiral lock.Spiral lock is being riveted on spiral lock peace
During dress plate, under depression bar 1 moment loading, lobe plate 4 applies axial thrust to rivet rod 5, promotes rivet rod 5 to being arranged on stud 6 glasss
Spiral lock direction motion in shape groove, rivet rod 5 cone ram impacts spiral lock cylinder makes spiral lock cylinder that radially expansion to occur
Open deformation, until the spiral lock with spiral lock installing plate installs riveting when 100 ° of counterbore conical surfaces of counterbore are fitted after spiral lock barrel distortion
Install into.
The fixing end of depression bar 1 is rotationally connected, by straight pin 15, the cam mechanism that lobe plate 4 is constituted.Lobe plate 4 contour curve
By circular arc and rectilinear(-al) eccentric cam, eccentric cam contact jaw is the sphere of radius 20mm, offer 0 ° under depression bar 1 acts on-
The anglec of rotation of 90 ° of scopes.Arch clamp 3 armstand afterbody U-lag provides 90 ° of positions spacing, on lobe plate 4 for its lobe plate 4
Boss provide 0 ° of position spacing for lobe plate 4.Rivet rod 5 external diameter is less than arch clamp 3 cross through hole internal diameter 0.2mm.Stud 6 with
The external diameter coupling of spiral lock, the cup-shaped groove internal diameter for installing spiral lock of stud 6 is more than spiral lock cylinder external diameter 0.1mm.Riveting
Bar 5 cone drift small end conical surface diameter mates with spiral lock cylinder internal diameter, than the little 0.1mm in spiral lock cylinder internal diameter footpath.Riveting
The frustoconical bevel angle of bar 5 cone drift is identical with the counterbore angle of spiral lock installing plate, is 100 °.Rivet rod 5 and stud 6 and
Spiral lock is coaxial.
The assemble flow of spiral lock riveting tool is as follows: stud 6 is arranged on arch clamp 3 by nut 12；Handle 2 leads to
Cross straight pin 14 to be arranged on arch clamp 3；Depression bar 1 and lobe plate 4 are dressed up by two pieces straight pin 13 riveting and are integrated；By resilience
Spring 10 is enclosed within rivet rod 5, and rivet rod 5 is loaded arch clamp 3；By straight pin 15, lobe plate 4 riveting is contained in arch clamp 3
On；Depression bar 1 is depressed into parallel with handle 2 (90 ° of positions), makes rivet rod 5 be in maximum and stretch out state (maximum travel position), will card
Ring 8, thrust spring 11, pressure ring 9, back-up ring 7 are contained on rivet rod 5 successively.
During with spiral lock riveting tool riveting spiral lock, the nut 12 utilizing stud 6 to assemble adjusts stud 6 axial stroke,
Making stud 6 be exactly equal to spiral lock installing plate thickness of slab size with the distance of rivet rod 5, spiral lock is assemblied in spiral lock peace by stud 6
In the counterbore of dress plate, make both be positioned in arch clamp 3 arcuate slots, and spiral lock installing plate keeps water with spiral lock body end surface
Flat；Then depression bar 1 is applied moment so that it is drive lobe plate 4 to rotate, and then promote rivet rod 5 to produce downward relative motion, work as riveting
When the bar 5 cone drift conical surface contacts with spiral lock installation cylinder, the rivet rod 5 cone drift conical surface starts its spiral lock is installed cylinder
Apply radial force, make spiral lock that cylinder dilatating and deformable to be installed；When depression bar 1 arrives 90 ° of positions, rivet rod 5 arrives range position
Putting, 100 ° of counterbore conical surfaces of spiral lock cylinder and spiral lock installing plate are fitted completely, and riveting completes；Cancel the moment to depression bar 1,
Under the effect of rebound spring 10, rivet rod 5 resilience, drive lobe plate 4 and depression bar 1 resilience, spiral lock riveting tool departs from spiral
Lock and spiral lock installing plate, riveting overall process is complete.
Below it is only the preferred embodiment of the present invention, it is noted that for the person of ordinary skill of the art,
On the premise of the creation design of the present invention, it is also possible to making some deformation and transformation, these are the protection of the present invention
Scope.
