Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.The present embodiment is implemented premised on technical solutions of the utility model, give detailed mode of execution and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
A kind of rotary-piston for printing plate cylinder locking, this rotary-piston is connected with air pump, comprise piston rod 5, also comprise cylinder block 1 and be located at the piston 2 that also can be free to slide in cylinder block 1 in cylinder block, piston 2 is provided with clutch shaft bearing 4, cylinder block 1 one end is provided with the second bearing 11, and piston rod 5 one end is connected with piston 2 by clutch shaft bearing 4, and the other end is stretched out cylinder block 1 and is connected with roller by the second bearing 11.
Cylinder block 1 inner chamber is divided into two chambers by piston 2, is equipped with the vent 13,14 be connected with air pump in two chambers.
Piston 2 is provided with the joint of cylinder block 1 and encloses 3 for improving a bubble-tight O shape.
Guide sleeve 7 is provided with between second bearing 11 and piston rod 5.
Guide sleeve 7 and piston rod 5 joint be provided with for improve bubble-tight 2nd O shape enclose 6 and the 4th O shape enclose 9.
One end that cylinder block 1 is connected with piston rod 5 is respectively equipped with cylinder cap 10 and flange 12, and flange 12 is located at cylinder block 1 end face, and flange 12 and cylinder cap 10 are placed in the second bearing 11 both ends of the surface respectively.
Be provided with between cylinder cap 10 and cylinder block 1 and enclose 8 for improving bubble-tight 3rd O shape.
During work, cylinder block 1 and flange 12 are arranged in roller, and when from vent 13 air inlet, when vent 14 is given vent to anger, piston 2 will move right together with piston rod 5, until roller is locked.When vent 14 air inlet, when vent 13 is given vent to anger, piston 2 will be moved to the left together with piston rod 5, now desirable go out roller.O shape circle 3,6,8, dust ring 9 will stop the leakage of gas, and the length of piston rod 5 and cylinder block 1 sets according to the Dimensions of roller, and thus in operation, the position of piston 2 is between vent 13,14 all the time.
After pneuma-lock, piston rod 5 will rotate together with roller.The spinning movement of piston rod is realized by the supporting of clutch shaft bearing 4 and the second bearing 11.The effect of guide sleeve 7 guides and support piston bar 5.
