Description

Novel air cylinder

Technical field

The utility model is related to a kind of Novel air cylinders.

Background technology

Single-acting cylinder only one end is into (row) gas, and simple in structure, air consumption is small；With the resets such as spring force or diaphragm power, pressure A part for contracting air energy reduces the power output of piston rod for overcoming spring force or membrane tension；Installation in cylinder Spring, diaphragm etc., general stroke are shorter；Compared with the double-acting cylinder of same volume, effective travel is smaller；Cylinder resets bullet Spring, the tension of diaphragm are with deformation size variation, thus the power output of piston rod is variation during advancing.Due to more than Feature, single action piston cylinder are chiefly used in short stroke.Its thrust and movement velocity are required to not high occasion, such as pneumatic hoist, positioning and On the devices such as clamping.The leakproofness of current single-acting cylinder is not fine, and oil resistant, non-refractory, are not suitable for severe yet Environment；And volume is larger, it is necessary to which cylinder is stored in larger space.

Utility model content

To overcome disadvantages mentioned above, the purpose of this utility model is to provide it is a kind of can play preferably sealing, can oil resistant it is resistance to High temperature, applied in adverse circumstances, compact, the Novel air cylinder that larger pressure can be generated.

In order to reach object above, the technical solution adopted in the utility model is：A kind of Novel air cylinder, including cylinder body, work Plug, air inlet, the piston are arranged in cylinder body and can be moved back and forth along the inner wall of cylinder body, the inner side end and cylinder of the piston Body forms acting chamber, and the air inlet is set on the cylinder body of acting chamber, and the end face outside of the piston is fixedly installed top Bar, the mandril are connected with the resetting structure of control piston reset, are set between the side wall of the piston and the madial wall of cylinder body Have two seals, wherein together the sealing ring close to the outside of piston, sealing ring described in another road close to the inside of piston, The two seals are using fluorubber, and the cylinder diameter of the cylinder body is 150-170mm, and the height of the cylinder body is 60-80mm.

The beneficial effects of the utility model are, after compressed gas enters acting chamber from air inlet, compressed gas effect is lived Plug pushes out, and final act on is moved outside mandril, and cylinder is in running order；During reset, by external resetting structure by piston reset； Two seals are provided on piston, wherein one of sealing ring is located on the outside of piston, another road sealing ring is located on the inside of piston, Preferable sealing is played, and using material of the fluorubber as two seals so that the Novel air cylinder being capable of the resistance to height of oil resistant Temperature can be applied in rugged environment；The cylinder body setting of cylinder body is decreased to 150-170mm, in the case of uniform pressure, energy Larger pressure is generated, the height of cylinder body is set in 60-80mm, compact.

Preferably, the cylinder diameter of the cylinder body is 160mm, and the height of the cylinder body is 70mm.

Be as further improvement of the utility model, the resetting structure include spring, connecting plate, the connecting plate with Mandril connects, and the spring is provided with multiple, and multiple springs are arranged between cylinder body and connecting plate.When cylinder is in work During state, spring is in tensional state, and after no longer compressed gas is blown into air inlet, the spring after stretching drives connecting plate to answer Position, since connecting plate is by mandril connection piston, during connecting sheet reset, piston also resets therewith.

Preferably, the connecting plate is threadedly coupled with mandril, and dismounting, installation are more convenient.

It is that the internal piston is provided with shoe cream room, the shoe cream room and peace as further improvement of the utility model The seal groove of dress two seals is connected by pipeline.Lubricating oil in shoe cream room leads to seal groove by pipeline, lubrication Sealing ring avoids the occurrence of the phenomenon that dropping due to sealing ring is dry and astringent in sliding process, and solving can not when sealing ring is dry and astringent The problem of playing sealing.

Preferably, the bore that the pipeline of seal groove is led to by shoe cream room is gradually reduced.Lubricating oil can be progressively given, is lubricated Oil can be provided persistently.

Preferably, oil filler point is provided on the piston, serum cap is provided on the oil filler point, the oil filler point passes through Oil filling pipeline connects shoe cream room.Oil filler point is to inject lubricating oil, after having noted lubricating oil, can serum cap be covered oil filler point.
