Abstract
The utility model relates to a telescopic cylinder which is composed of a large back cover, a large piston, a small piston, a small cylinder, a large cylinder, a piston rod, a large front cover and a small front cover. The small piston is provided at the left end of the piston rod. The small piston and piston rod are provided in the small cylinder. The left side of the small cylinder is provided with the large piston, and the right side is provided with the small front cover. The external part at the front end of the small cylinder is provided with an air outlet opening. The large cylinder is provided outside the small cylinder. The left side is provided with a large back cover, and the right side is provided with the large front cover. The utility model is characterized in that the gas hole which is at exterior part of the front end of the small cylinder is eliminated. An inner casing cylinder is provided between the small cylinder and the piston rod, and a composite bearing is provided between the small front cover and the large front cover. The advantage of the telescopic cylinder according to the utility model is the function that the speed can be regulated and the telescopic cylinder can be stopped in the operation course.
Description
Technical field
The utility model relates to a kind of telescopic cylinder, is applicable to that stroke is grown and the little occasion of installation axial dimension, is widely used in industries such as textile manufacturing machine, package packing machine, Transport Machinery, belongs to the cylinder technical field.
Background technique
Existing domestic production producer all adopts two joint cylinder barrels, and there is exhaust port little cylinder barrel front end outside, and in the whole service process, the uncontrollable motion speed of piston rod can't stop in the neutral position, and can not satisfy has requirement and the speed-regulating function that stops on the technology.
Summary of the invention
The purpose of this utility model is that invention is a kind of can the speed adjustment, the telescopic cylinder that operation can stop again midway.
For realizing above purpose, the technical solution of the utility model provides a kind of telescopic cylinder, by big bonnet, big piston, small piston, little cylinder barrel, big cylinder barrel, piston rod, big protecgulum, little protecgulum is formed, small piston places the left end of piston rod, small piston and piston rod place in the little cylinder barrel, the left end of little cylinder barrel is equipped with big piston, right-hand member is equipped with little protecgulum, and little cylinder barrel left end outside is equipped with exhaust port, and big cylinder barrel places outside the little cylinder barrel, left end is equipped with big bonnet, right-hand member is equipped with big protecgulum, it is characterized in that, casts out the pore of little cylinder barrel front end outside, cover cylinder in being equipped with between little cylinder barrel and piston rod is built-in with composite bearing at little protecgulum and big protecgulum.
The utility model saves to have increased in one on the cylinder barrel bases original two and overlaps cylinder, removed the structure that there is exhaust port former little cylinder barrel right-hand member outside, the interior cover cylinder that increases makes cylinder in whole to-and-fro motion, the runner of gas is a closure state, this cylinder is had can the speed adjustment, the function that operation can stop again midway; In big protecgulum, the little protecgulum composite bearing is housed all, has improved the greasy property and the working life of cylinder.
The utility model has the advantages that have can the speed adjustment, the function that operation can stop again midway.
Description of drawings
Fig. 1 is the telescopic cylinder structural representation.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 1, be the telescopic cylinder structural representation, form by big bonnet 1, big piston 2, small piston 3, interior cover cylinder 4, little cylinder barrel 5, big cylinder barrel 6, piston rod 7, big protecgulum 8, composite bearing 9, little protecgulum 10.
Make big bonnet 1, big piston 2, small piston 3, interior cover cylinder 4, little cylinder barrel 5, big cylinder barrel 6, piston rod 7, big protecgulum 8, composite bearing 9, little protecgulum 10, enter assembling after having cleaned each part.Open an aperture 11 at little cylinder barrel 5 left ends, Sealing is placed in separately the groove; Small piston 3 is installed on the piston rod 7, and the cover cylinder is 4 li in packing into nut is fastening; Composite bearing 9 is put into little protecgulum 10 and 8 li of big protecgulums respectively; The interior cover cylinder 4 that installs piston rod 7 is packed in the little cylinder barrel 5, and left end is screwed into big piston 2, and right-hand member is screwed into little protecgulum 10, guarantees the matching relationship between each; At last the above-mentioned parts that install are put into big cylinder barrel 6, the left side is screwed into big bonnet 1, and the right is screwed into big protecgulum 8, guarantees the matching relationship between each.
During cylinder operation, the requirement cylinder piston moves right, source of the gas is imported from cylinder left end rear end cover suction port, air pressure acts on respectively on big piston 2 and small piston 3 end faces, because big piston 2 areas are big, active force is big, big piston 2 motion earlier, the right chamber of big piston residual air is discharged by big protecgulum 8 input outlets, then little cylinder barrel 5 travels forward, and after putting in place, small piston 3 connects piston rod 7 and moves right, the residual air in small piston 3 right chambeies is passed through right-hand member aperture 12 by interior cover cylinder, annular pass through between interior cover cylinder 4 and the little cylinder barrel 5 flows into big cylinder barrel 6 right chambeies through the little cylinder barrel aperture in big piston 2 right-hand member places, discharges through big protecgulum 8 outlets, travel forward until piston rod and to put in place, in the whole process, gas is one-in-and-one-out in two runners separately of a sealing all, during as any one position halfway, as long as close the input outlet of cylinder front and rear covers, this cylinder then rests on any one position midway.Envelope formula solenoid valve then can reach the technological requirement that stops in the three-position five-way as long as connect in actual the use, mixes one-way throttle valve and can carry out the speed adjustment again.Otherwise the cylinder piston rod retracting motion flows to the gas reverse flow by above-mentioned former turnover, and to reset condition, in like manner any one position also can have the requirement of stop and the function of regulating the speed to cylinder piston rod halfway to swivel motion.
