Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, right
The present invention is further elaborated.It should be appreciated that specific embodiment described herein only in order to explaining the present invention, and
It is not used in the restriction present invention.
Referring to shown in Fig. 1, Fig. 1 is structural representation of air cylinder of the present invention.The present embodiment provides a kind of Novel air cylinder,
It mainly solves current cylinder function singleness and the problem do not grown service life.
Wherein said cylinder includes cylinder body 10, is provided with pull bar 90 outside described cylinder body 10.Cylinder body 10 is metal cylinder
Shape, is provided with cylinder chamber 11, cylinder body 10 sidewall is provided with two gas ports 12 in it, said two gas port 12 respectively with cylinder chamber
11 connections.
The front end of cylinder body 10 is mounted by means of screws with drive end bearing bracket 20, and rear end is mounted by means of screws with rear end cap
30.Wherein offering dead eye on drive end bearing bracket 20, in described dead eye, correspondence is provided with a swivel bearing 41 and a guiding
Bearing 42, described swivel bearing 41 is positioned above guide bearing 42, and the two is axially with one heart.
Cylinder chamber 11 is provided with a piston 50, described piston 50 is provided with a piston rod 40, this piston rod 40
It is connected through drive end bearing bracket 20 with swivel bearing 41 and guide bearing 42, and described piston rod the 40th, swivel bearing 41 and guide bearing
42 axially with one heart.
Cylinder chamber 11 is divided into having and sets on bar cylinder chamber and Rodless cylinder chamber two parts, and above-mentioned cylinder body 10 sidewall by piston 50
Two gas ports 12 put, one of them connects with there being bar cylinder chamber, and another connects with Rodless cylinder chamber.
When piston 50 stretching motion in cylinder chamber 11, in order to prevent piston 50 from damaging, arrange in the bottom of piston 50
There is a first cushion seal pad 60, when piston 50 moves to rear end cap 30 position, can be delayed by the first cushion seal pad 60
Punching prevents piston 50 from producing collision with rear end cap 30；Same, the top of piston 50 is correspondingly arranged on second cushion seal
Pad 70, when piston 50 moves to drive end bearing bracket 20 position, can prevent piston 50 and front end by the second cushion seal pad 70 buffering
Lid 20 generation collision.
The present embodiment is also installed with a piston revolving fragment 51 between piston 50 and the second cushion seal pad 70, lives
It is provided with a magnet ring 80 between plug revolving fragment 51 and piston 50.Piston revolving fragment 51 is an impeller, when air is from there being bar gas
The gas port in cylinder chamber enters fashionable, corresponding can form eddy current in cavity, to drive piston revolving fragment 51 to rotate, due to piston revolving fragment
51 are fixedly mounted on piston rod 40, therefore corresponding can produce the power rotating, and hard-wired bottom piston rod 40 are
Piston 50, therefore can make piston 50 also can concomitant rotation, thus accelerate air flowing in the cylinder, improve air
