As shown in Figure 3, Figure 4, in the embodiment of the present invention, described opening cavity bottom centre and wedge are put nail block 13 posterior center and are arranged with spring cavity respectively, and described second spring 17 two ends are positioned in two spring cavitys respectively.Described nail 13a front end of putting is provided with lead-in chamfered 13c, to facilitate rivet 5 to insert smoothly, avoids interfering.Described guide post 10 rear portion is provided with a connected unit, and described connected unit is inserted and sent in the chamber of nail seat 8 front end, is provided with sealing ring between connected unit outer peripheral face and chamber inner wall face.Sealing ring is provided with between the cock body 9a outer peripheral face at described piston 9 rear portion and described chamber inner wall face.
Operation principle of the present invention and the course of work as follows:
During without rivet 5, described piston 9 is in rear position under pneumatic action (the space air inlet on front side of piston 9 cock body 9a); Under the effect of the first spring 15, clip nail guide rod 11 is also in rear position; Wedge put nail block 13 and two wedge nail pressing blocks 14 under the effect of the second spring 17, the gap 14e width between two pieces of wedge nail pressing blocks 14 is 0, and namely two pieces of wedge nail pressing blocks 14 contact with each other.
As shown in Figure 3, when get nailing machine structure 6 rivet 5 got delivered to connect before nail feeding device for nail time, rivet 5 can be inserted in the 14a of nail pressing hole along the inclined-plane 14c that extends out putting nail 13a front end, due under the effect of the second spring 17, the male cone (strobilus masculinus) 14d of wedge nail pressing block 14 contacts with the inner conical surface of clip nail guide pin bushing 12 endoporus leading portion round taper hole, the single domatic 14b in wedge nail pressing block 14 rear end and wedge are put and are followed closely block 13 front end double slope surface 13b and contact, along with rivet 5 is toward feeding gradually in the 14a of nail pressing hole, gap 14e width between two wedge nail pressing blocks 14 can increase gradually, last rivet 5 enters into, and wedge nail pressing block 14 puts in nail 13a, when getting after nailing machine structure 6 removes, rivet 5 will be clamped under the effect of the second spring 17.
Then the rivet 5 of clamping is delivered to [riveted holes processes at last work step] in the riveted holes need riveting part 7 by the nail feeding device for nail that connects of the present invention, adopts cylinders providing power, is sent into by rivet 5 in the riveted holes on part 7; As shown in Figure 4, sending in nail process, part 7 can dock nail feeding device for nail a reaction force, this reaction force meeting stepless action is on stressed sheath 16, and put the retained part that forms of nail block 13, wedge nail pressing block 14 and clip nail guide pin bushing 12 by the effect of reaction force by wedge, clamp the positioning precision of rivet 5 after also just not affecting.After feeding puts in place, connecing nail feeding device for nail will stay in riveted holes by rivet 5, proceeds next step staking operation.But because this device is also in the state of clamping rivet 5, directly extract out if directly will connect nail feeding device for nail, rivet 5 also can be extracted out together.Now just need the space air inlet on rear side of to piston 9 cock body 9a, piston 9 is moved forward, promote clip nail guide rod 11 when piston 9 moves forward to travel forward under the guiding of guide post 10 pilot hole, when piston 9 moves to anteposition, two wedge nail pressing block 14 front ends will contact with stressed sheath 16 antetheca medial surface, the extending out inclined-plane 14c and can contact with the frustum 16a at stressed sheath 16 antetheca medial surface center and coordinate of 14a front end, nail pressing hole, two wedge nail pressing block 14 front ends outwards strut by frustum 16a, match because the domatic 14b of list of wedge nail pressing block 14 rear end puts with wedge the double slope surface 13b following closely block 13 front end simultaneously, under the second spring 17 acts on, two wedge nail pressing block 14 rear ends can outwards strut again by the double slope surface 13b that wedge puts nail block 13 front end, gap 14e between two wedge nail pressing blocks 14 can become larger than size during clamping rivet 5, until the nail pressing hole 14a diameter at nail pressing assembly center is greater than rivet 5 diameter.In the process, suffered because rivet 5 has now been inserted into riveted holes, rivet 5 meeting holding position is constant, and rivet 5 meeting and connect nail feeding device for nail depart from, to connect nail feeding device for nail again when extracting, rivet 5 will be stayed in the riveted holes on part 7, can carry out ensuing staking operation.
