The following provides two working methods of different buffer media according to the invention:
when compressed air is adopted as a buffer medium; when air is fed from the left air inlet:
as shown in fig. 1 and 2, when gas enters the left cavity inside the box 15 from the first gas source hole 13-2 of the left cylinder 13, the gas source acts on the surface of the left end of the rack 50 through the first buffer gas hole 13-3 to push the rack 50 to move rightward, the rack 50 drives the gear shaft 17 to rotate, when the rack 50 reaches the rightmost end, the gear shaft 17 completes the motion, and the motion stroke of the rack 17 can be any angle according to the design requirement. The high pressure actuator has a high operating pressure and a small volume, so that the high pressure actuator has a high operating speed, and a first buffer piston 28 is added at the end to reduce the impact. When the rack 50 moves to the rightmost end, the first buffer piston 28 enters the right second buffer chamber 14-1 of the right cylinder 14, and at this time, the compressed air in the right chamber can only pass through the second buffer air hole 14-3 and then reach the second air source hole 14-2, so as to be discharged out of the right cylinder 14. The flow cross-sectional area between the second buffer air hole 14-3 and the second air source hole 14-2 can be controlled by adjusting the screwing depth of the second adjusting needle valve 8, so that the purpose of adjusting the buffer speed is achieved.
When the rack 50 reaches the rightmost end, the rack will contact with the second adjusting bolt 2, and the output stroke of the gear shaft 17 can be adjusted by adjusting the retraction amount of the second adjusting bolt 2. The second sealing nut 4 is a sealing nut which can resist high pressure, and the second sealing nut 4 is locked and fixed after the position of the second adjusting bolt 2 is adjusted.
When air enters from the right air inlet, the action process is the same as the above process, when air enters the right cavity in the box body 15 from the second air source hole 14-2 of the right cylinder body 14, the air source acts on the surface of the right end of the rack 50 through the second buffer air hole 14-3 at the beginning to push the rack 50 to move leftwards, the rack 50 drives the gear shaft 17 to rotate, when the rack 50 reaches the leftmost end, the action of the gear shaft 17 is finished, and in order to reduce the impact, the second buffer piston 29 is added at the tail end. When the rack 50 moves to the leftmost end, the second buffer piston 29 enters the left first buffer chamber 13-1 of the left cylinder 13, and at this time, the compressed air in the left chamber can only pass through the first buffer air hole 13-3 and then reach the first air source hole 13-2, so as to be discharged out of the left cylinder 13. The flow cross-sectional area between the first buffer air hole 13-3 and the first air source hole 13-2 can be controlled by adjusting the screwing depth of the first adjusting needle valve 7, so that the aim of adjusting the buffer speed is fulfilled.
When the rack 50 reaches the leftmost end, it will contact the first adjusting bolt 1, and by adjusting the amount of retraction of the first adjusting bolt 1, the output stroke of the pinion 17 can be adjusted. The first sealing nut 3 is a sealing nut which can resist high pressure, and the second sealing nut 3 is used for locking and fixing after the position of the first adjusting bolt 1 is adjusted.
When hydraulic oil is used as a buffer medium, the action processes of the left cylinder body and the right cylinder body are the same, and only one side is described here:
when the rack 50 moves leftward to contact the piston rod 56 in the cushion cylinder 53. Hydraulic oil enters the right cavity from the left cavity through the buffer oil hole 59, the executing mechanism enters a buffer stroke, and a buffer effect is achieved through throttling of the buffer oil hole 59.
When the damping stroke is finished, in order to avoid damage to the spring due to the spring doubling-up, the piston 55 of the damping cylinder 53 has a convex portion, and in the extreme position, the convex portion is in contact with the end cover 57 of the damping cylinder 53.
When the rack moves to the right, the piston 55 of the damping cylinder 53 is reset under the action of the spring, and is ready for the next damping.
It is obvious that the above examples are only examples for clearly illustrating the present invention, and are not intended to limit the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. This need not be, nor should it be exhaustive of all embodiments. And obvious variations or modifications derived therefrom are intended to be within the scope of the invention.
