Abstract
The utility model relates to an air cylinder. The magnetic buffer air cylinder comprises an air cylinder barrel, a piston rod, a piston, a guide sleeve, a front end cover and a rear end cover, wherein the two side faces of the piston are respectively provided with an annular groove, a magnetic ring is arranged in each annular groove, the position, corresponding to the magnetic ring arranged on one of the side faces of the piston, of the front end cover is provided with an annular groove and a magnetic ring which is the same as the magnetic ring of the piston in magnetism, and the position, corresponding to the magnetic ring arranged on the other side face of the piston, of the rear cover is provided with an annular groove and a magnetic ring which is the same as the magnetic ring of the piston in magnetism. According to the magnetic buffer air cylinder, the piston are provided with the magnetic rings, the front end cover and the rear end cover are provided with the magnetic rings respectively, therefore, the magnetic rings on the piston repel the magnetic ring on the front end cover or the magnetic ring on the rear end cover when the piston gets close to the front end cover or the rear end cover so that the piston can be buffered against the front end cover or the rear end cover, and the magnetic buffer air cylinder is reasonable and simple in design, low in cost, reliable in performance, durable in use and suitable for wide-range production and application.
Description
Technical field
The utility model relates to a kind of cylinder, is specifically related to a kind of magnetic buffering cylinder.
Background technique
Pneumatic linear actuator is low because of its user cost in recent years, the characteristic of function admirable, as the power executive component, be widely used in various complete sets of equipment, because pressurized gas has very large elasticity in releasing course, so, when approaching end cap, cylinder produces impact phenomenon in the application of cylinder, a lot of cylinder interior are provided with buffer unit, at present, maximum method of being used by people has two kinds of spring and cushion collars, damping spring will occupy the very large space of cylinder body, increased the cylinder manufacture cost, cushion collar is the easy Flow valve installed additional in the unloading chamber, along with the termination position of piston near cylinder body, unloading gas reduces gradually, force the movement velocity of piston rod to reduce, reach cushioning effect.Because cushion collar will have certain move distance, and also will occupy the certain-length of cylinder barrel, the cylinder manufacture cost is invisible also will be increased.In addition, gas density is very little, high to the parts required precision, meets cushioning effect fully, is not easy to accomplish.The magnetic buffering cylinder can make up the deficiency of above-mentioned two kinds of buffering methods fully.
The model utility content
The purpose of this utility model is the problem and shortage for above-mentioned existence, and a kind of magnetic buffering cylinder of principle of magnet ring homopolar-repulsion that can be contrary by magnetic force is provided.
For achieving the above object, technical solution adopted in the utility model is:
A kind of magnetic buffering cylinder, comprise cylinder barrel, piston rod, piston, guide sleeve, front cover and rear end cover, described piston bi-side are equipped with annular groove, be provided with magnet ring in annular groove, the magnet ring position be provided with on corresponding to the piston bi-side at front cover and rear end cover also is provided with annular groove and same sex magnet ring.
Described guide sleeve is arranged on the front cover outside, and the guide sleeve internal circular surfaces is provided with seal ring.
Adopt technique scheme, the obtained beneficial effect of the utility model is:
A kind of magnetic buffering cylinder of the utility model, by magnet ring is installed respectively on piston, front cover, rear end cover, make piston respectively with front cover or rear end cover near the time produce homopolar-repulsion effect, play buffer function, reasonable in design, simple, with low cost, reliable performance, durable in use, be applicable to producing on a large scale and applying.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Number in the figure: 1 be cylinder barrel, 2 for piston rod, 3 for piston, 4 for guide sleeve, 5 for front cover, 6 for rear end cover, 7 for magnet ring, 8 for seal ring.
Embodiment
Referring to Fig. 1, a kind of magnetic buffering cylinder of the utility model, comprise cylinder barrel 1, piston rod 2, piston 3, guide sleeve 4, front cover 5 and rear end cover 6, described piston 3 bi-side are equipped with annular groove, be provided with magnet ring 7 in annular groove, magnet ring 7 positions that are provided with on corresponding to piston 3 bi-side at front cover 5 and rear end cover 6 also are provided with annular groove and same sex magnet ring.
Described guide sleeve 4 is arranged on front cover 5 outsides, and guide sleeve 4 internal circular surfaces are provided with seal ring 8.
The utility model by installing respectively magnet ring on piston, front cover, rear end cover, make piston respectively with front cover or rear end cover near the time produce homopolar-repulsion effect, play buffer function, reasonable in design, simple, with low cost, reliable performance, durable in use, be applicable to producing on a large scale and applying.
Claims (2)
1. a magnetic buffering cylinder, comprise cylinder barrel, piston rod, piston, guide sleeve, front cover and rear end cover, it is characterized in that, described piston bi-side are equipped with annular groove, be provided with magnet ring in annular groove, the magnet ring position be provided with on corresponding to the piston bi-side at front cover and rear end cover also is provided with annular groove and same sex magnet ring.
2. magnetic buffering cylinder according to claim 1, is characterized in that, described guide sleeve is arranged on the front cover outside, and the guide sleeve internal circular surfaces is provided with seal ring.
