The operation principle and the course of work of the present invention is as follows：
During without rivet 5, the piston 9 is in pneumatic action（Space air inlet on front side of the cock body 9a of piston 9）Rear position is in down；
In the presence of first spring 15, clip nail guide rod 11 is also at rear position；Wedge puts nail block 13 and two wedge nail pressing blocks 14 second
In the presence of spring 17, the gap 14e width between two pieces of wedge nail pressing blocks 14 mutually connects for piece wedge nail pressing block 14 of 0, i.e., two
Touch.
As shown in figure 3, when the rivet 5 taken is delivered to and connect before nail feeding device for nail by nail extracting machine 6, rivet 5 can be along putting
The inclined-plane 14c that extends out of nail 13a front ends is inserted into the 14a of nail pressing hole, due in the presence of second spring 17, wedge nail pressing block 14
Male cone (strobilus masculinus) 14d contacted with the inner conical surface of the endoporus leading portion round taper hole of clip nail guide pin bushing 12, the single domatic 14b in the rear end of wedge nail pressing block 14
The nail front end double slope surface 13b of block 13 is put with wedge to contact, as rivet 5 is toward being progressively fed in the 14a of nail pressing hole, two wedge nail pressing blocks
Gap 14e width between 14 can gradually increase, and last rivet 5 enters putting in nail 13a on wedge nail pressing block 14；When taking
After nailing machine structure 6 is removed, rivet 5 will be clamped in the presence of second spring 17.
Then the rivet 5 of clamping is sent in the riveted holes that need to rivet part 7 by the nail feeding device for nail that connects of the invention【Riveted holes
Processed in previous work step】, using cylinders providing power, rivet 5 is sent into the riveted holes on part 7；Such as Fig. 4 institutes
Show, during nail is sent, part 7, which can dock nail feeding device for nail, a reaction force, and the meeting stepless action of this reaction force exists
On stress sheath 16, and put that retained part that nail block 13, wedge nail pressing block 14 and clip nail guide pin bushing 12 constitute is not counter to be made by wedge
Effect firmly, clamps the positioning precision of rivet 5 after also just not influenceing.After sending into place, nail feeding device for nail is connect by riveting
Nail 5 is stayed in riveted holes, proceeds the staking process of next step.But due to the present apparatus also in clamping rivet 5 state, such as
Fruit will directly connect nail feeding device for nail and directly extract out, and rivet 5 can also be extracted out together.Now it is accomplished by rear side of the cock body 9a of piston 9
Space air inlet, move forward piston 9, piston 9 move forward when promote clip nail guide rod 11 under the guiding of the pilot hole of guide rod 10
Travel forward, when piston 9 is moved to anteposition, two front ends of wedge nail pressing block 14 will connect with the antetheca medial surface of stress sheath 16
Touch, extending out inclined-plane 14c and being engaged with the frustum 16a at the antetheca medial surface center of stress sheath 16 for nail pressing hole 14a front ends is bored
Platform 16a outwards struts two front ends of wedge nail pressing block 14, simultaneously because the domatic 14b of list and wedge of the rear end of wedge nail pressing block 14
The double slope surface 13b for putting nail block 13 front end is engaged, and under the effect of second spring 17, wedge puts the double slope surface 13b of nail block 13 front end
Two rear ends of wedge nail pressing block 14 can outwards be strutted again, the gap 14e between two wedge nail pressing blocks 14 can become than clamping
Size during rivet 5 is big, until the nail pressing hole 14a diameters at nail pressing assembly center are more than the diameter of rivet 5.In the process, by
In rivet 5 riveted holes have now been inserted into suffer, rivet 5 can holding position it is constant, and meeting of rivet 5 and to connect nail feeding device for nail de-
From, then when will connect nail feeding device for nail extraction, rivet 5 will be stayed in the riveted holes on part 7, can carry out ensuing staking
Process.
