Description
Technical field
A kind of high leakproofness piston-rodless cylinder is the utility model is related to, belongs to pneumatic gearing field of mechanical technique.
Background technology
At present, with automated manufacturing, the extensive application of pneumatic robot, the demand of small stroke reciprocating is also increasingly
More, common double rod cylinders, due to being single-piston structure, reciprocal efficiency is low, and can not realize effective Stroke Control.It is existing
Without piston-cylinder because driving tongue piece sealing structure is bad, often result in the reduction of cylinder action power, influence stroke accuracy, reduce gas
The cylinder life-span.
Utility model content
Purpose：In order to overcome the deficiencies in the prior art, the utility model provides a kind of high leakproofness piston-rodless
Cylinder.
Technical scheme：In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of high leakproofness piston-rodless cylinder, including：Gray iron, tongue piece, upper sealant, lower sealant, saddle,
The cylinder body both ends are connected with cylinder cap, and guide rod is respectively and fixedly provided with the inside of the cylinder cap；Moved respectively on two guide rod free ends
Piston is socketed with, two piston ends are connected by connecting rod；Opening is provided with above the cylinder body, opening, which is provided with, to be led
Xiang Huan, on guide ring movement be socketed with saddle；The lower sealant is with after the upper mutual clamping in sealant both ends, being separately fixed at cylinder
Between body and cylinder cap, tongue piece is provided between the lower sealant and upper sealant；The cylinder body has been respectively arranged below two
Stomata.
Preferably, in addition to sealing ring, described sealing ring one end are fixed in guide ring bottom interior wall, sealing ring
The other end is caught in the vertical groove of saddle bottom, is bolted on saddle.
Preferably, the upper sealant is provided at both ends with claw, and lower sealant is provided at both ends with voussoir.
Preferably, in addition to O-ring seal, it is provided with O-ring seal between the piston and guide rod.
Preferably, the piston is arranged to U-shape structure, and piston nose is provided with inclined-plane；The tongue piece both ends point
Inclined-plane is not provided with, and tongue piece both sides are respectively arranged with location-plate.
Preferably, the saddle top is provided with screw.
Beneficial effect：A kind of high leakproofness piston-rodless cylinder provided by the utility model, it is reciprocating by two
Piston, the tongue piece between lower sealant and upper sealant is jacked up upwards respectively, tongue piece again jacks up saddle upwards, so as to realize
Saddle pumps.The design of lower sealant, upper sealant, effectively solve the problems, such as to seal at cylinder opening, together
When sealing ring is added between the guide ring and saddle of mobile link, more effectively realize overall sealing effectiveness.Originally set
Simple structure is counted, cylinder seal performance is good, the reciprocal efficiency high of saddle, each part fixing compact, service life length.
