In the process of the nail of assembling buffering in the past, because buffering nail material is rubber, elastic deformation amount is large, automatic mounting timing easily produces two kinds of situations, first pressure head direction has deviation, and pressure head can make to cushion nail head, and active force is not applied to buffering nail afterbody, cause buffering to be bound not in place, secondly, when pressure head vertically declines, although ram travel puts in place, but due to the bounce-back of buffering nail head, cause buffering nail afterbody not necessarily to put in place completely.So the utility model has designed and has been pressed into the push-and-pull that cooperatively interacts of cylinder module, clamping cylinder module, draft cylinder module and solves this two problems, and complete assembling: the first step, while being pressed into the decline of cylinder module, pressure head 151 head copyings, make buffering nail have a correcting, then the afterbody that clamping cylinder module clip locking buffering is followed closely, then by draft cylinder module, buffering nail is pulled and put in place, concrete operation method is as follows:

1, by plastic casing and four manual prepackages of buffering nail, put into housing positioning clamping fixture 4;

2, automatic operation switch in start-up operation interface module 6, being pressed into cylinder 111 presses down automatically, make four pressure heads 151 heads that four bufferings of corresponding compression are followed closely one by one respectively on plastic feet, and the afterbody of the nail of buffering now embeds in the left and right jig arm of chuck 225, then on clamping cylinder 222, move, make wedged block 224 between the bottom of the left and right jig arm of below embedding chuck 225, thereby the top that makes chuck 225 clamps the afterbody of buffering nail, last draft cylinder 311 drives clamping cylinder fixed head 241 to move down, also be that clamping cylinder fixed head 241 drives pinch-grip agency to moving down, thereby buffering nail is pulled and put in place.

If 3 bufferings are followed closely neglected loadings or do not install to position, buffering nail assembling device is reported to the police, and quits work.

If 4 buffering nails are without neglected loading or installed to position, in buffering nail assembling device, be pressed into that cylinder 111 band dynamic heads 151 move on together, clamping cylinder 222 drives wedged blocks 224 to move down together, thereby chuck 225 unclamps buffering nail.

5, the manual buffer gear assembling that takes out.
