Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
A kind of three cylinders described in the utility model, comprise cylinder body 3, piston rod 6, fixed plate 1, described cylinder body 3 two ends are provided with protecgulum 5 and bonnet 14, be provided with in the cylinder body 3 can be free movable the piston group, described piston rod 6 one ends pass protecgulum 5 and are connected with the piston group, piston rod 6 the other ends and 1 vertical connection of fixed plate; Described cylinder body 3 both sides have bullport 12, and described bullport 12 is parallel with piston rod 6, and bullport 12 front ends are provided with guide pin bushing 9, are provided with guide rod 2 in the bullport 12, and described guide rod 2 one ends pass guide pin bushing 9 and 1 vertical connection of fixed plate.
Above-mentioned parts are the utility model agent structure.
Have inlet hole A4 on the described cylinder body 3, go up inlet hole B41, following inlet hole A7 and following inlet hole B71, have through hole 8 and following through hole 10 in the cylinder body 3, described upward inlet hole A4 and last inlet hole B41 are communicated with by the active chamber of last through hole 8 with piston group one side, and through hole 10 was communicated with the active chamber of piston group opposite side under described inlet hole A7 down and following inlet hole B71 passed through.
Described piston group comprises secondary piston 13 and back piston 16, and back piston 16 is sheathed on piston rod 6 one ends, and back piston 16 is provided with magnet ring 11, and secondary piston 13 is spirally connected with piston rod 6 one ends.
Described piston group two ends are equipped with cushion pad 15; Described cylinder body 3 bottoms are provided with induction groove 17, and cylinder body 3 is provided with some fixed holes 18.
Working principle: cylinder 3 can seal inlet hole and following inlet hole on one of them by plug 19 according to installation requirements in use; When last inlet hole in the cylinder body 3 during input pressurized air, pressurized air moves downward the piston group by last through hole 8, drives piston rod 6 and then fixed plate 1 is moved to cylinder 3, fixed plate 1 drives the guide rod 2 of both sides along guide pin bushing and piston rod 6 synchronous movements simultaneously; Instantly inlet hole in the cylinder body 3 during input pressurized air then fixed plate 1 oppositely move; The cushion pad 15 that piston group two ends arrange makes the piston group can not produce too big impact when arriving at range; Magnet ring 11 cooperates automatically with the magnetic switch of being located at cylinder body 3 bottoms when piston moves to be controlled; Some fixed holes 18 can be fixed in cylinder 3 on the frame by bolt.
