Multifunctional efficient air-or liquid-operated device
Technical field
The utility model relates to a kind of pneumatic or Hydraulic actuator, is specially a kind of multifunctional efficient air-or liquid-operated device.
Background technique
The Pneumatic actuator of the switch of existing control gate only has two limit positions, this Pneumatic actuator does not have centre or middle part position of rest, more automatically do not return middle locating function or other random locating functions, although thus this Pneumatic actuator tool has many advantages, but still be difficult to apply in other interior more wide fields at such as truck shift speed change, the potentiality limiting Pneumatic actuator play.
Existing truck lacks high-efficiency multi-function air-or liquid-operated device.The shift speed change of existing truck moves realization by the driven gear such as shift handle, connecting rod shift fork.Its deficiency: one is gearshift difficulty.Because connecting rod moves, there is frictional force, and the frictional force being connected hinge between connecting rod with shift handle is comparatively large, needs larger power when making to shift gears, gearshift difficulty; Two is that gearshift is difficult to put in place.Owing to being realize hinged by pin, bulb between shift handle and connecting rod, in use for some time, pin, mouth, connecting rod, bulb etc. all can wear and tear, produce gap, thus not only operating difficulties, and gearshift not easily puts in place, and even bulb comes off and occurs accident; Three is that gearshift is heavy.The motor of truck is larger, and will assemble corresponding large speed changer, synchronizer, gear shift operation is very heavy, gruelling; Four is that installation and maintenance are difficult.Because the installing space of each mechanism of shift speed change is little, make installation and maintenance loaded down with trivial details, difficult; Five be manufacture, use, maintenance cost is many.Some truck adopts electrical control shift, further increases the complexity of structure, and assembling uses loaded down with trivial details, and cost is high, and use and maintenance cost is many.
Model utility content
The purpose of this utility model is exactly will for above-mentioned deficiency, a kind of multifunctional efficient air-or liquid-operated device is provided, it has two or more location, spacing controls, a certain precalculated position at the volley can be stopped, the motion control in multiple precalculated position can be performed, and manipulating easy, light, registration, installation and maintenance are easy, and manufacture, installation, maintenance cost is low.
For achieving the above object, the technical solution of the utility model is, this multifunctional efficient air-or liquid-operated device, comprise the cavity with piston, described piston is connected with piston rod, and described piston has piston cavity, be provided with inner chamber piston at described piston cavity, this inner chamber piston has inner chamber piston rod.Like this, inner chamber piston rod can move in cavity or in piston cavity, form location, make the overall a certain required particular location be positioned in cavity of described piston, also can when piston rod be motionless, by inner chamber piston rod, transmission of power is gone out outside piston cavity or outside cavity, perform other actions.
Be provided with at least two inner chamber pistons at described piston cavity, these inner chamber pistons have inner chamber piston rod respectively.Like this, piston cavity can be made to form more than one chamber, each inner chamber piston has the inner chamber piston rod of transferring power.Inner chamber piston rod can multidimensional (multi-direction) be arranged, and realizes multi-faceted transferring power, performs multidimensional action.
Described inner chamber piston can in opposite directions or reverse motions.By giving this different chamber air feed or the liquid with the piston cavity of multi-chamber, make different inner chamber piston produce motion, the transmission of power and the function that obtain different azimuth perform.
Described inner chamber piston rod has the bar medium channel being communicated with piston cavity, and this bar medium channel is communicated with the end medium channel of described cavity end.Described medium can be can the gas of transmitting force or liquid.This bar medium channel, the end medium channel be interconnected, can fed sheet of a media (gas or liquid) and do not affect that it is movable swimmingly, and each organization establishes can be made more reasonable, compacter, is conducive to manufacturing and safeguarding.
The piston rod of described connection piston is arranged on the middle part of inner chamber piston rod.This set is more reasonable, compacter, is conducive to manufacturing and safeguarding.
Described inner chamber piston rod does not stretch out cavity or part does not stretch out cavity.This inner chamber piston rod does not stretch out the setting of cavity, is conducive to piston in cavity, locates or locate spacing operation, be conducive to the stroke shortening piston rod, improve the operational efficiency of piston; Described inner chamber piston rod portion does not stretch out the setting of cavity, when can be implemented in piston operation or location, is performed the action in other orientation by the inner chamber piston rod stretching out cavity.
The position-limit mechanism of inner chamber piston is provided with or/and the length of described inner chamber piston rod can be stretched at the chamber wall of described piston cavity.The position-limit mechanism of the chamber wall of inner chamber piston can realize the location, stroke etc. of inner chamber piston; By changing the length of described inner chamber piston rod, the location of inner chamber piston, stroke etc. also can be realized.
Compared with the prior art, piston described in the utility model has piston cavity, is provided with inner chamber piston at described piston cavity, and this inner chamber piston has inner chamber piston rod; Described inner chamber piston rod has the bar medium channel being communicated with piston cavity, and this bar medium channel is communicated with the end medium channel of described cavity end; The piston rod of described connection piston is arranged on the middle part of inner chamber piston rod; Be provided with at least two inner chamber pistons at described piston cavity, these inner chamber pistons have inner chamber piston rod respectively; Described inner chamber piston rod does not stretch out cavity or part does not stretch out cavity.Because these arrange characteristic and the function of existing pneumatic or Hydraulic actuator.
The utility model can be used for the control performing more complicated multi-faceted action, as the control of the gearshift speed regulating control of truck, the door of multi-faceted multipoint positioning range hold switch, etc., it has two or more location, spacing controls, and can stop a certain precalculated position at the volley, can perform the motion control in multiple precalculated position, and manipulate easy, light, registration, installation and maintenance are easy, and manufacture, installation, maintenance cost is low.
