The specific embodiment
With reference to Fig. 1～6, the present invention includes holder 1, telescopic 2, thrust spring 3, spring adjustment seat 4, push rod 6, sealing ring 7, friction top 8, adjust ring 9, bearing 10, coil tension spring 11, rotary sleeve 12, spring base 13, crank throw seat 14, crank throw 16, slide block 19 and grab ring 20.Holder 1 is to have the penetrating body of boss, uniform four grooves of holder inwall 1-1, telescopic 2 is installed in the holder 1, its external diameter with holder inwall 1-1 mating part is more smaller than holder inwall, matched in clearance, and in the relevant position uniform four grooves, key 15 is fixed in the groove, cooperate with the groove on the holder inwall 1-1, guaranteed not deflection in the descending process of telescopic 2.The top of telescopic 2 and holder 1 mating part have adjusts ring 9, by adjusting the relative position of ring on the H of axis, the up stop of telescopic 2 is limited.Like this, when upper cylinder 5 action, owing to be matched in clearance between holder 1 and the telescopic 2, telescopic 2 and all parts that are installed in its inside move downward.Boss in the holder 1 cooperates with the boss on the telescopic 2 fixes coil tension spring 11, and coil tension spring 11 is that all parts that make telescopic 2 and be installed in its inside can upwards reset when upper cylinder 15 is withdrawn automatically in effect.In telescopic 2, rotary sleeve 12 is installed, can be relatively rotated reposefully between rotary sleeve 12 and the telescopic 2 by bearing 10.Spring base 13 is equipped with at the center of rotary sleeve 12, and a face of spring base 13 contacts with the shaft shoulder of push rod 6, and its top is fixed with spring by internal thread and adjusts seat 4; Spring base 13 is adjusted seat 4 with spring and is placed in opposite directions, pass push rod 6 therebetween and be placed with thrust spring 3, spring base 13, spring are adjusted seat 4 and push rod 6 matched in clearance, and at the mating surface of spring adjustment seat 4 and push rod 6 sealing ring 7 are arranged, sealing lubricating oil and avoid dust to fall into; Be fixed with friction top 8 on the top of rotary sleeve 12, bearing 10 played the sealing function of bearing (ball) cover.Be fixed with crank throw seat 14 on the boss of the latter half inner chamber of rotary sleeve 12, crank throw 16 is hinged by pin joint 22 and crank throw seat 14, and is hinged by straight pin 17 and slide block 19.The C type mouth of crank throw 16 encases the boss on the push rod 6, and when the moving up and down under the effect of lower cylinder 18 and retainer spring 3 of push rod 6, its boss can promote crank throw 16 downward or upward around its pin joint 22 swings.It is radially flexible to drive slide block 19 by straight pin 18 in the time of crank throw 16 swings.Be fixed with on the slide block 19 and grab ring 20, its external diameter is identical or bigger with annular plain film 21 internal diameters, can encircle 20 by changing grabbing of various outer diameter, realizes grasping the annular plain film 21 of different inner diameters.
When upper cylinder pushed away for 5 times, the mechanism's integral body except that holder 1 moved down; Simultaneously, penetrator ram 6 on the lower cylinder 18, make and push away crank throw 16 on its convex platform, and drive slide block 19 arrival backstop a places, grab in the ring 20 and contract, and the acting in conjunction result of these two actions is: grab ring 20 and stretch among the internal spline 21-1 of annular plain film 21.Afterwards, lower cylinder 18 at first resets, and the lower convex platform of push rod 6 promotes crank throw 16 downwards under the effect of thrust spring 3, drive slide block 19 and be back to backstop b place, grabs the ring 20 outer promptly annular plain films 21 of opening.Then, cylinder 5 resets, and under coil tension spring 11 effects, the mechanism's integral body except that holder 1 is finished the extracting process of an annular plain film with annular plain film 21 withdrawals of grasping.
The size range of annular plain film internal diameter is 70～120mm.When the annular plain film internal diameter size changes less than 5mm, adjust seat 5 and the relative position of lower cylinder 18 on the H of axis by adjusting spring, thereby reach the purpose of adjusting the retract stroke of grabbing ring 20; When the annular plain film internal diameter size changes above 5mm, at first change and grab ring 20, adjust spring again and adjust seat 5 and the relative position of lower cylinder 18 on the H of axis, finally reach the purpose of extracting different inner diameters size annular plain film.
