Abstract
The utility model discloses a pneumatic difunctional two-way reciprocatory motion mechanism. A first cylinder and a second cylinder are respectively arranged on left side and the right side of the mechanism, a piston rod and a valve body assembly are connected between the two cylinders, a reversing valve and a sliding plate are mounted on the valve body assembly, a first pick bearing and a second pick bearing are further arranged on the valve body assembly, a spring I and a first spring sleeve are arranged in the first pick bearing, a spring II and a second spring sleeve are arranged in the second pick bearing, a pick I and a pick II are abutted against sliding blocks to move leftwards and rightwards under the action of the spring I and the spring II, and the reversing valve is a sliding-plate type and realizes on and off of air ways by changing opposite position of the sliding plate and the valve body. The sliding plate moves in a radial direction, so that reversing forming is short, air changing is fast, and the cylinders can move in reciprocation rapidly; and since the sliding-plate type structure is adopted, the pneumatic difunctional two-way reciprocatory motion mechanism is free of backpressure, good in sealing effect and long in service life.
Description
Technical field
The utility model relates to the pneumatic product field, is specifically related to reciprocating type pneumatic hydraulic switching mechanism.
Background technique
The existing pneumatic reciprocating mechanism most critical point problem of in gas circuit, how taking a breath exactly, just the structure of selector valve is very important, and the structure that has selector valve now mainly contains:
1, slide column type, it is the cylindrical body that shoulder is arranged with, in tubular valve sleeve, move along its axis, realize the valve of gas path on-off, its shortcoming is that the commutation stroke of spool is long, and the valve volume of big latus rectum is excessive, to the impurity sensitivity in the medium, so higher to the source of the gas processing requirements.
2, seat valve formula, spool is greater than the Sealing of the disk of valve base aperture or other shapes valve that moves axially to switch air flue along valve seat in its structure, and its shortcoming is the circulation area of the existence that back pressure is arranged, particularly valve when big, can form very big switching resistance.
Solution like this, valve seat adopt the balanced type valve core structure or use big control piston to promote the spool commutation, and for the big valve seat of latus rectum, then use pneumatic control formula or guide's controlling method, and so structure becomes complicated, and cost rises.
The model utility content
Problem to be solved in the utility model is that device is a kind of can to commutate and simple in structure, compact, very effective fast sharing between two cylinders of a piston rod, and when gas circuit commutates, less demanding to gas, just can realize gas path on-off, thereby finish the two-way quick to-and-fro motion of twin-tub.Use this device commutation for single air cylinder structure and can realize quick to-and-fro motion too.
For addressing the above problem, the utility model is realized by following scheme: a kind of pneumatic double-action bidirectional reciprocating motion.First cylinder and second cylinder are set about this mechanism, connect piston rod, valve body assembly in the middle of two cylinders, at valve body assembly selector valve and slide plate are installed, this valve body assembly also is equipped with the first plectrum supporting base and the second plectrum supporting base, the built-in spring one of the described first plectrum supporting base and first spring housing, the built-in spring two of the second plectrum supporting base and second spring housing, plectrum one withstands the slide block move left and right respectively with plectrum two under the effect of this spring one and spring two.
In described first cylinder piston one is housed, in described second cylinder piston two is housed, be connected by piston rod between described piston one and the piston two.
Described slide block is shaped as " worker " font, with the ingenious combination of slide board type scavenging way.
The utility model selector valve is slide board type, and it is to realize gas path on-off by the relative position that changes slide plate and valve base chamber; Slide plate radially moves, so the commutation stroke is short, ventilation can make cylinder realize quick to-and-fro motion rapidly, because selector valve has adopted this unique texture of slide board type, no back pressure, sealing is good, the life-span is long, and is less demanding to source of the gas.

Embodiment
Below be in conjunction with embodiment and description of drawings the utility model to be further described:
As shown in Figure 1, first cylinder 1 and second cylinder 2 are set about this mechanism, in first cylinder 1 piston 1 is housed, in second cylinder 2 piston 24 is housed, connect piston rod 5 in the middle of two cylinders, valve body assembly 6, be connected by piston rod 5 between piston 1 and the piston 24, the first plectrum supporting base 7 and the second plectrum supporting base 8, the first plectrum supporting base, 7 built-in springs 1 and first spring housing 13, the second plectrum supporting base, 8 built-in springs 2 10 and second spring housing 14, plectrum 1 withstands slide block 12 move left and right respectively with plectrum 2 16 under the effect of this spring 1 and spring 2 10.
As shown in Figure 2, at valve body assembly 6 selector valve 9 and slide plate 17 are installed, when the output pressurized gas enters first cylinder, 1 right side when indoor, piston 1 is moved to the left, and slide block 12 is moved to the left simultaneously, stirs slide plate 9 and is moved to the left, second cylinder, 2 inner carriers 24 also are moved to the left, when piston 1 moved to the leftmost side, selector valve switched, and gas enters in second cylinder, the 2 left side gas compartments, piston 24 moves right, slide block 12 drive slide plates 17 move right simultaneously, and piston 1 and then moves right, when piston 24 is gone to the rightmost side, selector valve 9 switches, having begun gas again, to enter first cylinder, 1 right side indoor, and piston 1 begins mobile left, repeats mobile so like this, just form the two-way to-and-fro motion of cylinder, whole motion process has been used simple structure, and not fragile, and the life-span is long.
This having " worker " word shape slide block and slide board type reversing arrangement to be applied in the Gas-liquid pump also be good scheme.As shown in Figure 3, comprise drive cylinder 18, reversing arrangement 20, clutch release slave cylinder 21, air flue 19,
It is except the characteristics that have diaphragm pump and have, and also possessing has the output of flow high-pressure liquid, if high property by to drive cylinder 18, the vary in diameter of clutch release slave cylinder 21 then has different flow and high-pressure liquid output.High performance-price ratio be diaphragm pump can't than, and volume is little, it is low to consume energy, power is big.
