Abstract
The utility model relates to a long-stroke air cylinder and belongs to the pneumatic field. An air cylinder is mounted in a large air cylinder and used as a piston rod of the large air cylinder, an extension part of the small air cylinder is communicated with the large air cylinder, and a telescopic part of the small air cylinder is same with an external air pipe via a telescopic hose. When the air cylinder extends under control of an electromagnetic valve, the total stroke is the sum of the strokes of the large air cylinder and the smaller air cylinder. When the air cylinder retracts, the total length of the air cylinder is the length of the large cylinder, and the long-stroke (double-stroke) air cylinder is realized.
Description
Technical field:
The utility model belongs to pneumatic field.
Technical background:
Existing cylinder stroke all can not be greater than the length of cylinder, will increase like this cylinder usage space and cost, also can limit the using scope of cylinder.
Summary of the invention:
For the deficiency of existing cylinder, the utility model provides a kind of long stroke cylinder, makes cylinder stroke exceed the length of cylinder.
The utility model is to realize like this, on large cylinder, three tracheaes (tracheae A of head is installed, two tracheae B of afterbody and tracheae C), in large cylinder, little cylinder is installed, little cylinder serves as the piston rod of large cylinder, the afterbody of little cylinder is provided with large cylinder piston, little cylinder connects with large cylinder, on small cylinder piston, there is a penetration hole, a Telescopic flexible pipe one end is connected with small cylinder piston penetration hole, the other end is connected (as connected cylinder C) with one of them tracheae of large tail cylinder, cylinder is work like this, in the time that cylinder extends, under the control of solenoid valve, tracheae B air inlet, tracheae A exhaust, simultaneously under the control of another solenoid valve, gas in little cylinder is through Telescopic flexible pipe, by tracheae, C discharges, gas just promotes large cylinder piston and small cylinder piston travels forward like this, drive little cylinder and little cylinder column to travel forward, just realize cylinder in the time extending, its stroke is the stack of large cylinder and little cylinder stroke, in the time that cylinder shrinks, under the control of solenoid valve, tracheae A air inlet, tracheae B exhaust, simultaneously under the control of another solenoid valve, tracheae C air inlet, enter in little cylinder through Telescopic flexible pipe, gas just promotes large cylinder piston and small cylinder piston moves backward like this, drive little cylinder and little cylinder column to move backward, just realizing little cylinder is retracted in large cylinder, the length of whole cylinder is the length of large cylinder, realize a kind of long stroke (double-stroke) cylinder, principle according to this, also can manufacture the cylinder (as triple-travel cylinder) of longer stroke, in the time that cylinder shrinks, in order to prevent that small cylinder piston is retracted in large cylinder block, therefore at stingy cylinder club head, damp block is installed.
A kind of so long stroke cylinder will reduce cylinder usage space and cost, also can expand the using scope of cylinder.
Brief description of the drawings:
Fig. 1 is this cylinder profile front view;
Fig. 2 is this cylinder cutaway top view;
In figure: 1 is tracheae C; 2 is tracheae B; 3 is large cylinder; 4 is tracheae C; 5 is little cylinder; 6 is little cylinder column; 7 is bellows; 8 is large cylinder piston; 9 is small cylinder piston; 10 is damp block.
Below in conjunction with accompanying drawing, enforcement of the present utility model is described further:
Embodiment:
The utility model is to realize like this, on large cylinder 3, three tracheaes (tracheae A4 of head is installed, two tracheae B2 of afterbody and tracheae C1), in large cylinder 3, stingy cylinder 5 is installed, stingy cylinder 5 serves as the piston rod of large cylinder 3, the afterbody of stingy cylinder 5 is provided with large cylinder piston 8, stingy cylinder 5 connects with large cylinder 3, on small cylinder piston 9, there is a penetration hole, Telescopic flexible pipe 7 one end are connected with small cylinder piston 9 penetration holes, the other end is connected with the tracheae C1 of large cylinder 3 afterbodys, cylinder is work like this, in the time that cylinder extends, under the control of solenoid valve, tracheae B2 air inlet, tracheae A4 exhaust, simultaneously under the control of another solenoid valve, the gas that stingy cylinder is 5 li is through Telescopic flexible pipe 7, by tracheae, C1 discharges, gas just promotes large cylinder piston 8 and small cylinder piston 9 travels forward like this, drive stingy cylinder 5 and little cylinder column 6 to travel forward, just realize cylinder in the time extending, its stroke is the stack of large cylinder 3 and stingy cylinder 5 strokes, in the time that cylinder shrinks, under the control of solenoid valve, tracheae A4 air inlet, tracheae B2 exhaust, simultaneously under the control of another solenoid valve, tracheae C1 air inlet, enter 5 li, stingy cylinder through Telescopic flexible pipe 7, gas just promotes large cylinder piston 8 and small cylinder piston 9 moves backward like this, drive stingy cylinder 5 and little cylinder column 6 to move backward, just realizing stingy cylinder 5 is retracted in large cylinder 3, the length of whole cylinder is the length of large cylinder 3, realize a kind of long stroke (double-stroke) cylinder, principle according to this, also can manufacture the cylinder (as triple-travel cylinder) of longer stroke, in the time that cylinder shrinks, in order to prevent that small cylinder piston 9 is retracted in large cylinder 5 cylinder bodies, therefore at little cylinder column 6 heads, damp block 10 is installed, in the present embodiment, bellows 7 is corrugated hose.
