The operation principle and the course of work of engine gudgeon pin jump ring assemble mechanism of the present invention are described below:
The a plurality of piston pin clamping springs of suit on the stock column of feeding device, piston pin clamping spring is through conducting oneself with dignity to pressing down.
When needing piston pin clamping spring is installed; Pusher master cylinder 24 drives scraping wings 22 jump ring 20 is advanced blanking slope 31; Jump ring 20 drops in the fluting 6 on the jump ring pressure head 2 along blanking slope 31, and pusher master cylinder 24 actions then drive scraping wings 22 and and then return to original position together; Jump ring 20 deadweights simultaneously descend, and wait for next pusher.Between stock column 19 and the installation plate 21 structure that has the gap is set, this gap is greater than the thickness of scraping wings 22 and jump ring 20, and therefore, scraping wings 22 can be released jump ring 20 from this gap, and can only release a jump ring 20 at every turn.After jump ring 20 dropped in the fluting 6 on the jump ring pressure head 2, under the control of controller 10, stage clip master cylinder 24 promoted to press-fit bar 17; Thereby promote jump ring pressure head 2, distribution cover 11 and press-fit guide pillar 3 to travel forward, at this moment, the jump ring 20 in the fluting 6 is pushed to piston pin hole 9 directions simultaneously; When jump ring pressure head 2 withstands piston pin hole 9, press-fit guide pillar 3 and continue reach, in injecting piston pin hole 9; After jump ring 20 was pressed into piston pin hole 9, jump ring 20 was compressed into the locating slot of piston pin hole 9.Because the ram cavity 5 of jump ring pressure head 2 is set to from the bullet structure of progressively dwindling to jump ring pressure head outer face 13 1 end diameter dimensions with jump ring pressure head end 12; Therefore, when jump ring 20 is press-fiting guide pillar 3 and the promotion of promoting cover 11 down during entering jump ring pressure head 2, jump ring 20 is along with near piston pin hole 9 one sides; And dwindle gradually; Because the size in the hole on the jump ring pressure head outer face 13 of jump ring pressure head 2 and piston pin hole more at present, and jump ring pressure head 2 is during with piston pin hole 9 applyings, and the ram cavity 5 on the jump ring pressure head outer face 13 is aimed at piston pin hole 9 fully; Like this, being convenient to jump ring 20 is press-fited guide pillar 3 and promotes cover 11 and push in the piston pin hole 9.
In the assemble mechanism of the present invention; Described distribution cover 11 is a spring steel; Has rigidity and elasticity, so when distribution cover 11 was compressed into jump ring pressure head 2, the inwall that distribution cover 11 is pasting jump ring pressure head 2 all the time slowly dwindled and promotes jump ring 20 forward and moves; Jump ring 20 also dwindles according to the vary in diameter of jump ring pressure head 2 inwalls simultaneously, finally sticks in the locating slot in the piston pin hole 9.Be processed with a type conical bench 33 in the middle of press-fiting guide pillar 3; Such structure; Guarantee that jump ring pressure head 2 and distribution cover 11 are resisted against piston pin hole 9 outer rear flank; Press-fit guide pillar 3 and move on, after in press-fiting guide pillar 3 reeve piston pin holes 9, realizing locating, and type conical bench 33 is used to limit the degree of depth that press-fits guide pillar 3 insertion piston pin holes 9.
Describedly press-fit guide pillar 3 when being in the duty of stretching out to piston pin hole 9 directions; Return spring 32 is set to apply the structure of reciprocal power to press-fiting guide pillar 3; Like this, after jump ring 20 installed, return spring 32 can be realized jump ring pressure head 2, distribution cover 11 and press-fit the return of guide pillar 3.
Combine accompanying drawing that the present invention has been carried out exemplary description above; Obviously the concrete realization of the present invention does not receive the restriction of aforesaid way; As long as the various improvement of having adopted method design of the present invention and technical scheme to carry out; Or design of the present invention and technical scheme are directly applied to other occasions without improving, all in protection scope of the present invention.
