Abstract
The utility model provides a buffering anti-collision cylinder comprising a cylinder body (10), a piston (20), a piston rod (30), a front cover (11) and a rear cover (12). The piston (20) and the piston rod (30) are arranged in the cylinder body (1), and the front cover (11) and the rear cover (12) are arranged on two ends of the cylinder body (1). The piston rod (30) penetrates through the front cover (11) and is connected with the piston (20). The buffering anti-collision cylinder is characterized in that a ring-shaped concave anti-collision cushion sheet (40) is arranged between the front cover (11) and the piston (20). The concave face of the anti-collision cushion sheet (40) faces the front cover (11). The anti-collision cushion sheet (40) is sleeved on the piston rod (30) and covers towards the inner side face of the front cover (11). The buffering anti-collision cylinder has the advantages of having buffering function on the two ends, protecting the piston from being damaged, and prolonging service life of the cylinder when the piston does reciprocating motion.
Description
Technical field
The utility model is a kind of cushion bumper cylinder.
Background technique
Cylinder is a kind ofly can convert compressed-air actuated pressure into mechanical energy; The machinery that driving mechanism is done straight reciprocating motion, swings and rotatablely moved; Usually be applied to fields such as machining, automation control, its working principle is to promote piston motion through pressurized air, and piston promotes piston rod and moves; Drive other mechanism's to-and-fro motion again, to reach the manufacture control purpose.Because piston needs to-and-fro motion in cylinder, so piston takes place and the cylinder cap case of collision through regular meeting.In the one side that piston is promoted by air pressure, owing to there is air pressure, this face of piston can receive pressure buffer when cylinder cap moves; Make that the impact events of piston and cylinder cap is also not serious, but, do not have air pressure at the another side that piston is not promoted by air pressure; When the cylinder cap of this face moves, have no buffer function at piston, the impact events that piston and cylinder cap take place is just relatively more serious; Make piston impaired, have a strong impact on cylinder working life.
The model utility content
The purpose of the utility model provides a kind of cushion bumper cylinder, and it has the piston of making when to-and-fro motion, and all there is pooling feature at two ends, and the protection piston is not damaged, and prolongs the cylinder advantage in working life.
In order to realize this purpose, the technological scheme that the utility model adopts is following: the cushion bumper cylinder comprises cylinder body; Be positioned at the piston and the piston rod of cylinder body, and the protecgulum and the bonnet that are positioned at the cylinder body two ends, said piston rod passes protecgulum and is connected with piston; It is characterized in that; Be provided with the crashproof pad of annular concave between said protecgulum and the piston, the concave surface of said crashproof pad is towards said protecgulum, and said crashproof pad is enclosed within on the said piston rod and covers to the protecgulum inner side surface.
Preferably, also be provided with piston packing between said crashproof pad and the piston.
Preferably, also be provided with the cushion seal circle that is placed on the piston rod between said crashproof pad and the said protecgulum.
Preferably, said protecgulum is provided with adjustable trimmer valve.
Preferably, said piston is provided with magnet ring and wear ring.
Compared with prior art, the utility model is provided with the crashproof pad of annular concave in the side that piston does not receive air pressure; The concave surface of said crashproof pad is towards said protecgulum, said crashproof pad be enclosed within on the said piston rod and lid to the protecgulum inner side surface, when piston in cylinder during to-and-fro motion; In the one side that piston is promoted by air pressure, owing to there is air pressure, this face of piston can receive pressure buffer when cylinder cap moves; And the another side that not promoted by air pressure at piston, when piston when the cylinder cap of this face moves, form a closed air chamber between crashproof pad and the protecgulum; The inner little air that exists is compressed, and makes the air pressure fast rise piston to be formed certain buffer function; The buffer function that combines crashproof pad itself simultaneously; Make the bump that piston and cylinder cap take place alleviate, the protection piston is not damaged, and has prolonged the working life of cylinder.

Embodiment
Below in conjunction with accompanying drawing and embodiment the technological scheme of the utility model is described.
The utility model is a kind of cushion bumper cylinder, comprises cylinder body 10, is positioned at the piston 20 and piston rod 30 of cylinder body 10; And the protecgulum 11 and bonnet 12 that are positioned at cylinder body 10 two ends; Said piston rod 30 passes protecgulum 11 and is connected with piston 20, it is characterized in that, is provided with the crashproof pad 40 of annular concave between said protecgulum 11 and the piston 20; The concave surface of said crashproof pad 40 is towards said protecgulum 11, and said crashproof pad 40 is enclosed within on the said piston rod 30 and covers to protecgulum 11 inner side surfaces.Compared with prior art, the utility model is provided with the crashproof pad 40 of annular concave through a side that does not receive air pressure at piston 20, and the concave surface of said crashproof pad 40 is towards said protecgulum 11; Said crashproof pad 40 be enclosed within on the said piston rod 30 and lid to protecgulum 11 inner side surfaces, when piston 20 in cylinder during to-and-fro motion, the one side that promoted by air pressure at piston 20; Owing to there is air pressure, piston 20 these faces can receive pressure buffer when cylinder cap moves; And the another side that not promoted by air pressure at piston 20, when piston 20 when the cylinder cap of this face moves, closed air chamber of formation between crashproof pad 40 and the protecgulum 11; The inner little air that exists is compressed, and makes the air pressure fast rise piston 20 to be formed certain buffer function; The buffer function that combines crashproof pad 40 itself simultaneously; Make piston 20 and the bump that cylinder cap takes place alleviate, protection piston 20 is not damaged, and has prolonged the working life of cylinder.
In order further to promote cushioning effect; Piston 20 must further compress air; So that have better sealability between crashproof pad 40 and the piston 20; Therefore also be provided with piston packing 50 between said crashproof pad 40 and the piston 20,, strengthen buffer function to promote the sealability between crashproof pad 40 and the piston 20.In addition, also be provided with the cushion seal circle 60 that is placed on the piston rod 30 between said crashproof pad 40 and the said protecgulum 11, also can increase cushioning effect.For the different working requirement; Gas pressure in the cylinder is also different, and therefore the buffer function power to piston 20 has different requirement, must regulate the gas flow between piston 20 and the protecgulum 11; Said protecgulum 11 is provided with adjustable trimmer valve 70; Can the adjustments of gas amount, change the size of buffer function power, to satisfy under the different operating condition requirement to cushioning effect.Said piston 20 is provided with magnet ring 80 and wear ring 90, can reduce the wearing and tearing to piston 20.
The purpose of the utility model provides a kind of cushion bumper cylinder, and it has the piston of making when to-and-fro motion, and all there is pooling feature at two ends, and the protection piston is not damaged, and prolongs the cylinder advantage in working life.
