Description
Technical field
The present invention relates to a kind of cylinder, particularly relate to a kind of multiple-pass cylinder.
Background technique
Current cylinder is many to be made up of single layer structure, and be only provided with a piston rod and a piston, the stroke that each piston rod stretches out is fixed, and cannot meet the needs of various service condition, versatility is poor, uses and is limited to.
Summary of the invention
In order to solve, cylinder in prior art is many to be made up of single layer structure, only be provided with a piston rod and a piston, the stroke that each piston rod stretches out is fixed, cannot meet the needs of various service condition, versatility is poor, uses the problem of being limited to, the invention provides a kind of structure simple, easy to use, different stroke can be realized, the good multiple-pass cylinder of versatility.
In order to solve the problem, the technical solution used in the present invention is:
A kind of multiple-pass cylinder, comprise cylinder barrel, it is characterized in that: also comprise first piston, second piston, 3rd piston, first piston bar, second piston rod, 3rd piston rod, first collision block and the second collision block, first piston bar is provided with in cylinder barrel, second piston rod, 3rd piston rod, first piston rod rear end is provided with first piston, the rear end of first piston is provided with the first collision block, the rear end in contact of described first collision block has the second piston rod, second piston rod rear end is provided with the second piston, the rear end of the second piston is provided with the second collision block, the 3rd piston rod is had in the rear end in contact of the second collision block, described 3rd piston rod rear end is provided with the 3rd piston, described first piston, second piston, 3rd piston be all connected with the air chamber passing into gas to it.
Aforesaid a kind of multiple-pass cylinder, is characterized in that: described first piston bar, the second piston rod, the 3rd piston rod have identical axle center.
Aforesaid a kind of multiple-pass cylinder, is characterized in that: described 3rd piston press-in stroke is the shortest, and described first piston press-in stroke is the longest.
Aforesaid a kind of multiple-pass cylinder, is characterized in that: described first collision block adopts stainless steel material to make.
Aforesaid a kind of multiple-pass cylinder, is characterized in that: described piston rod adopts resistant material material to make.
Aforesaid a kind of multiple-pass cylinder, is characterized in that: described air chamber adopts stainless steel material to make.
The invention has the beneficial effects as follows: multiple-pass cylinder of the present invention is made up of multilayer, every layer has an independently cylinder, and each cylinder has different strokes, and the piston rod of each cylinder is independently.During work, each cylinder does not pass into pressed gas simultaneously, but passes into pressed gas separately according to range demands.The present invention the 3rd piston stroke is the shortest, and first piston stroke is the longest.When needing shortest route, air chamber on the right side of 3rd piston has passed into body of calming the anger, promote the 3rd piston and with the 3rd piston rod move right, 3rd piston rod promotes the second piston rod by the second collision block, second piston rod promotes first piston bar by the first collision block again, and first piston bar obtains minimum stroke (stroke of the 3rd piston).When needing most Long travel, the air chamber on the right side of first piston bar has passed into body of calming the anger, and the distance that first piston bar stretches out equals the stroke of first piston.Need reset time, the right side air chamber of first piston has passed into body of calming the anger, first piston bar promote the second piston rod so that promote the 3rd piston rod get back to initial position.
Accompanying drawing explanation
Fig. 1 is multiple-pass structural representation of air cylinder of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, a kind of multiple-pass cylinder, comprise cylinder barrel 1, first piston 2, second piston 3, 3rd piston 4, first piston bar 5, second piston rod 6, 3rd piston rod 7, first collision block 8 and the second collision block 9, in cylinder barrel, 1 is provided with first piston bar 5, second piston rod 6, 3rd piston rod 7, first piston bar 5 rear end is provided with first piston 2, the first collision block 8 is provided with in the rear end of first piston 2, the rear end in contact of described first collision block 8 has the second piston rod 6, second piston rod 6 rear end is provided with the second piston 3, the rear end of the second piston 3 is provided with the second collision block 9, the 3rd piston rod 7 is had in the rear end in contact of the second collision block 9, described 3rd piston rod 7 rear end is provided with the 3rd piston 4, described first piston 2, second piston 3, 3rd piston 4 be all connected with the air chamber passing into gas to it.Described first piston bar 5, second piston rod 6, the 3rd piston rod 7 have identical axle center.It is the shortest that described 3rd piston 4 is pressed into stroke, and it is the longest that described first piston 2 is pressed into stroke.Described first collision block 8 adopts stainless steel material to make.Described piston rod adopts resistant material material to make.Described air chamber adopts stainless steel material to make.
In sum, multiple-pass cylinder of the present invention is made up of multilayer, and every layer has an independently cylinder, and each cylinder has different strokes, and the piston rod of each cylinder is independently.During work, each cylinder does not pass into pressed gas simultaneously, but passes into pressed gas separately according to range demands.The present invention the 3rd piston 4 stroke is the shortest, and first piston stroke 2 is the longest.When needing shortest route, air chamber on the right side of 3rd piston 4 has passed into body of calming the anger, promote the 3rd piston 4 and with the 3rd piston rod 7 move right, 3rd piston rod 7 promotes the second piston rod 6 by the second collision block 9, second piston rod 6 promotes first piston bar 5 by the first collision block 8 again, and first piston bar 5 obtains minimum stroke (stroke of the 3rd piston).When needing most Long travel, the air chamber on the right side of first piston bar 5 has passed into body of calming the anger, and the distance that first piston bar 5 stretches out equals the stroke of first piston 2.Need reset time, the right side air chamber of first piston 2 has passed into body of calming the anger, first piston bar 5 promote the second piston rod 6 so that promote the 3rd piston rod 7 get back to initial position.
