Description

Using pressure fluid as the flexible acting device of power

Technical field

The design is a kind of device that flexible work done can be achieved under the action of control valve for power using pressure fluid, The device of traditional cylinder oil cylinder can be especially replaced in part special dimension.

Background technology

Currently known applying pressure fluid realizes that the device of flexible acting has cylinder and oil cylinder.These devices are effective Be applied to it is various mechanically.But cost and to all very high by the requirement of the mechanical rigging position precision of driving.Be not suitable for dusty, High corrosion and the environmental works such as underwater.Have currently on the market referred to as；Pneumatic artificial muscle is that a kind of applicating fluid pressure contractions are done The device of work(.Its defect is that mode of work-doing is single.

Invention content

It is power that the purpose of the design, which is to provide a kind of usable Fluid pressure, of low cost, can be in various adverse circumstances Acting device work, that no piston simple in structure stretches controllable.Including；With recuperability contraction acting device, can stretch Long acting device, the two-way work doing device with elongation with contraction.

What the purpose of the design was realized in；A kind of contraction acting device of applicating fluid pressure：Internal layer is arranged one Two pipe fittings are arranged in expandable rubber pipe, one high strength fibre woven tube of outer suit, compound rubber bore both ends, according to Woven network tube and rubber tube are sealed jointly by seamless clip and are pressed on pipe fitting, there are one will be external for setting on pipe fitting Fluid is characterized in the hole of the rubber tube supply pressure fluid that rises of compound tube, the design；It may be provided with outside woven network tube Bounce back rubber tube, and retraction rubber tube terminal and woven network tube and inside, which can rise, to be pressed on by seamless clip respectively together with rubber tube , it can be achieved that the contraction acting ability with recuperability on two pipe fittings.

Can rise be knitted into rigid backbone in rubber tube or woven network tube, mesh grid is woven to triangular mesh, close knits use It can not significantly be deformed in limitation region of interest, realize elongation acting structure.

Contraction and elongation can be realized when contraction acting device is designed to be integrated with elongation acting device coaxial combination Two-way work doing.

Due to take above-mentioned design scheme can realize spring-like reset using Fluid pressure extend or shrink workmanship Device and two-way work doing device.The installation cost is cheap, assembly is simple, highly practical, working environment adaptability is strong, can apply The pressure fluid control system execution of existing maturation controls.

The design is further illustrated with embodiment below in conjunction with the accompanying drawings.

Figure 10 is the contraction acting state of Fig. 9 shown devices.

Specific implementation mode：

See the rubber tube of mono- high-strength high-elasticity of Fig. 1（1）, outside is set with one and presses certain geometry knot by high strength fibre The tubular reticulum (2) of structure mesh knitted is set with a slat gum pipe (3) outside tubular reticulum again, in order to reach certain pressure resistance with it is flexible The requirement mesh grid of power and rubber tube can multilayer intussusceptions.The compound tube both ends of the hole of set poststack, which is respectively cooperating with, is put into a pipe fitting (4), using the general seamless clip in Pneumatic hydraulic field（5）By compound tube both ends excircle part and the pipe for stretching into pore part Joint sealing is locked.It is provided with the hole being connect with fluid circuit on the end of wherein one pipe fitting or exposed circle（6）, two end pipes Connector is both provided with and is driven external mechanical mating connection structure（7）, connection structure cooperation is by driving machinery, Ke Yifen Flange, connecting plate, axis and screw thread etc. are not made, and can be set as overall structure with pipe fitting.

When braided mesh geometry is quadrangle or more, mesh grid can stretch in diagonal sees Fig. 2.

Fig. 3 indicates, when assembly shown in FIG. 1 mesh shown in use Fig. 2, to pass through the piping connection hole on pipe fitting （6）The charged pressure fluid internal layer rubber tube forced expansion into compound tube squeezes mesh grid and is deformed along mesh diagonal, whole Body expands, and compound tube is become arc from original linear type, causes the change of both ends pipe fitting spacing and externally does work, Mesh grid outer rubber tube compressing establishment network recovery original form after pressure relief, it is multiple that this function is equivalent to traditional spring The oil cylinder or cylinder of the tension type acting of position.

When Fig. 4 expressed portion lacing knitmesh passes are triangle or close knit of latitude and longitude will limit relevant range deformation.

Fig. 5 is indicated when in woven network tube（2）Upper braiding is embedded to rigid backbone（8）（9）, woven tube is made to form bellows structure When can realize that embedment position distortions limitation, internal layer can rise sebific duct（1）Outer layer sebific duct（3）It presses device and resets form making, Fig. 6 is the state for generating elongation acting shown in Fig. 5 after charged pressure fluid.Outer layer sebific duct forces device multiple after pressure relief Position.

When in woven network tube（2）Upper braiding is embedded to rigid backbone（8）（9）Afterwards, then with rubber-coating can replace individually The rubber tube that rises.Different rigid backbone quantity, which is arranged, can realize required range demands.

Shown in Fig. 7；That rigid backbone is directly embedded to the rubber tube that can rise, the deformation after inflation by Fig. 8 shows.Work as operation force When degree does not require very high, managed with retraction to realize that elongation acting can save mesh grid.

Fig. 9 is to can be achieved to shrink the elongation acting state with elongation two-way work doing.It is characterized in that shrink acting device with Elongation acting device coaxial combination design is integrated, so that it may be shunk and elongation two-way work doing with realizing.Elongation acting compound tube（1） It is made of with rigid backbone the inner layer woven tube that rubber tube can not be deformed significantly with outer layer that can rise, or is being connected with rigid backbone It is directly coated with rubber in woven tube and forms fiber rubber multiple tube.Pipe both ends are fixed on pipe fitting by gapless clip（3）（4） Inner ring on.Shrink acting compound tube（2）It is made of with the deformable woven tube of outer layer the internal layer rubber tube that can rise, compound tube both ends are leaned on Gapless clip is fixed on pipe fitting（3）（4）Outer shroud on.Gas port（5）It is connected to the gap between two compound tubes, gas port （6）Connection elongation acting combination tube cavity.

Figure 10 is the contraction acting state of Fig. 9 shown devices

It should be filled between sebific duct and mesh grid in Fig. 1 and flexible acting device shown in fig. 5 corrosion-free to above-mentioned material Lubricant.Filling with sealant is needed on the webmaster of compound tube cooperation pipe fitting length, mesh is filled and led up using fluid sealant, then Recycle clip（5）Compound tube is locked to pipe fitting（4）On.

The shape of rigid backbone can be set according to requirement of engineering, and desired stroke is realized in size cooperation.With a constant pitch Spring can also be embedded to can rise rubber tube or high strength fibre mesh grid, realize elongation acting.

The size of contractility is determined by the product of maximum secting area and fluid pressure after the expansion of combination tube cavity.

Greatest limit contractility by internal layer sebific duct ultimate tensile intensity, fiber wire rod single line ultimate tensile intensity with pressed The product for being attached to total radical that pipe fitting is reached the standard grade codetermines.
