The specific embodiment
A kind of plastic pin machine head, comprise head base plate 1, head cover plate 2, supporting setting ejector pin mechanism, be installed on dialling the pin stock and being arranged at the ratchet mechanism of dialling pin stock lower end on the head base plate; The thimble 6 that ejector pin mechanism comprises cylinder 3, is arranged at the contiguous block 5 of cylinder piston rod 4 front ends and is arranged at contiguous block 5 front ends; Ratchet mechanism comprise and dial the hinged shank 7 of pin stock, with the check rod 8 of shank 7 overlap joints, be arranged between shank 7 and the check rod 8 ratchet 9 and with group pin gear 10 of ratchet 9 coaxial settings; On head cover plate 2, be provided with the gathering sill 16 that thimble 6 moves up and down.
Be provided with in the upper end of dialling the pin stock can with the eave tile 11 of plane overlap joint on the contiguous block 5, be provided with compression spring 12 between pin stock and the head base plate 1 dialling, compression spring 12 is vertically placed, its lower end is dropped on group pin stock.
Between shank 7 and check rod 8, be provided with the second compression spring 17.
Dial the pin stock and comprise stock 13 and following stock 14, connect through extension spring 15 between last stock and the following stock, compression spring 12 is arranged between stock 13 and the head base plate 1.
The utility model and notification number are that the difference of the disclosed a kind of plastic pin machine head of the utility model patent of CN 201989441U is: 1, on head cover plate 2, be provided with the gathering sill 16 that thimble 6 moves up and down; 2, the compression spring that is located between head base plate 1 and group pin stock is different with both position relations, and the compression spring drops on and dials on the pin stock in the utility model, and the latter drops on the head base plate 1; 3, dial the descending promotion that no longer needs cylinder piston rod 4 of pin stock, so no longer the ladder platform need be set; 4, the spring that is pressed on shank 7 and check rod 8 on the ratchet 9 does not re-use two, and changes shared one second compression spring 17 into; 5, dial the pin stock and be divided into upper and lower two parts, connect through extension spring 15 between two parts; 6, be provided with the adjusting rod 18 of regulating check rod 8 upper-lower positions.
When cylinder piston rod 4 is up; By stock 13 in contiguous block 5 direct pulls, the resistance that overcomes compression spring 12 and extension spring 15 upwards moves, and spurs down stock 14 through extension spring 15; Descend stock 14 to drive on the shank 7 then and move, make ratchet 9 rotate a position.When cylinder piston rod 4 is descending; Contiguous block 5 leaves stock 13, then go up stock 13 the compression spring 12 effect under, be displaced downwardly to withstand down stock 14 after; Stock 14 is also moved down together; Thereby make shank 7 descending, remove to hook the next tooth of ratchet 9, ready for stir ratchet 9 next time.
The gathering sill 16 that thimble 6 moves up and down is set on head cover plate 2, makes the motion of thimble 6 more accurate, prevent fractureing or bending of thimble 6; Dial the up of pin stock and drive eave tile 11 realizations through cylinder piston rod 4 and contiguous block 5; Dial pin stock compression compression spring 12 simultaneously; Produce and dial the descending power of pin stock, and no longer be to need the descending of cylinder piston rod 4 to realize that group pin stock is descending, so the stroke of cylinder piston rod 4 no longer is restricted; Just can change stroke through block is set in the groove of its motion, thereby be convenient to change the draw point 19 of different length; A spring is set between shank 7 and check rod 8, is adjacent to the bill of shank 7 and check rod 8 on ratchet 9, be no longer necessary for them spring is set separately separately; Connect through extension spring 15 between last stock 13 and the following stock 14, make its push pull maneuver softer, be convenient to control shank 7; Through the setting of adjusting rod 18, can regulate suitable upper-lower position for check rod 8.
