Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
The structure of existing vane-type pneumatic rotary actuator can, referring to the sketch of Fig. 3, comprise stator 1, rotor 2, cylinder body 3, blade 4, the first gas port 5, the second gas ports 6.Described stator 1 is fixedly connected with cylinder body 3; Described blade 4 is fixedly connected with rotor and can rotates by rotor driven 2; Described the first gas port 5 is arranged on a side of stator 1, and described the second gas port 6 is arranged on the opposite side of stator 1.
In the time of the first gas port 5 air inlet, blade 4 is turned clockwise by gas push rotor driven 2, and the motion of blade 4 causes the second gas port 6 exhausts.Blade 4 clockwise motion is blocked stop motion until run into stator 1.Principle promotion blade 4 same when the second gas port 6 air inlet rotates counterclockwise.And as shown in Figure 3, if blade 4 turns to and is close to stator 1 lateral location, although blocked stop motion by stator 1, also lack enough areas of exerting pressure simultaneously because fitting completely and lose the power returning by " locked ".For ensureing the power of reciprocating stroke, should avoid blade and stator to fit completely.The method generally adopting is the hunting range that reduces blade 4, and before touching stator 1, stop motion finishes stroke.Therefore, existing cylinder cannot provide larger pendulum angle.
The sectional view of a kind of big swing angle vane-type pneumatic rotary actuator of the present utility model as shown in Figure 1, improves on the basis of existing vane-type pneumatic rotary actuator: the both sides of stator 1 at least respectively arrange 1 block 101, spacing for to blade 4.
In the present embodiment, the both sides of stator 1 respectively arrange two blocks 101.Can see from Fig. 1, block 101 is arranged on stator 1 and is fixedly connected with cylinder body 3 near one end of cylinder body 3.Set in the time that blade 4 clockwise rotates the position contacting with block 101, the space that a side of described stator 1 and blade 4, cylinder body 3 surround is second space, and second space is corresponding with the second gas port 6; In the time that blade 4 rotates counterclockwise the position contacting with block 101, the space that the opposite side of described stator 1 and blade 4, cylinder body 3 surround is the first space, and the first space is corresponding with the first gas port 5.The shape size of block is determined by concrete condition, need guarantee that the first gas port 5 is arranged in the first space all the time in the swing process of blade 4, and the second gas port 6 is arranged in second space all the time.In the present embodiment, block 101 is illustrated in figure 2 stator 1 in 2/3rds of this direction length at rotor 2 footpaths extended length upwards, and the surperficial shape that block 101 contacts with blade 4 matches with cylinder body 3, blade 4.In the present embodiment, being provided with of block shape, position is beneficial to the pendulum angle that maximizes blade 4, but the utility model is not limited to this.
The both sides of the first gas port 5, the second gas port 6 position next-door neighbour's stator 1 on cylinder body 3.Because the thickness of block 101 is determined with respect to the pore size of position, the first gas port 5 and second gas port 6 of stator 1 jointly by the first gas port 5 and the second gas port 6, the both sides that the position of the first gas port 5, the second gas port 6 is arranged on to next-door neighbour's stator 1 can maximize the pendulum angle of blade 4 in reducing block 101 thickness.The first gas port 5, the second gas port 6 also can be set to and stator 1 segment distance of being separated by, and the thickness of block 101 also needs correspondingly to increase, and this design belongs to category of the present utility model, but such design is unfavorable for the expansion of full swing angle.
In the utility model, block 101 and blade 4 are different materials, both can prevent the viscous in to-and-fro motion process, also can reduce friction.
By structure of the present utility model, even if blade goes to limit position, still can ensure sufficient inner chamber, to hold pressed gas.By flexible hose and rapid pipe joint, two gas circuits are connected with the first gas port 5, second gas port 6 of cylinder body 4.When Dang Yi road air inlet, another road exhaust, does clockwise and anticlockwise swing thereby utilize pressurized air to promote blade rotor driven.In the utility model, the shape of block 101 and position are not limited to the present embodiment, also can design at stator 1 near one end of rotor 2 or other other positions.
The disclosed cylinder of the utility model can also increase adjusting normal valve of the prior art, in 0-90 ° 0-180 °, 0-270 °, 0-330 ° or other several angular ranges, realize the swing of adjustable pivot angle, can make to the utlity model has multiple mode of operations with the combination application that regulates normal valve, adapt to the demand of various different pivot angles.Because the application that regulates normal valve is prior art, seldom explanation herein.
The utility model is by special structural design, retain the former advantageous while at vane-type pneumatic rotary actuator, both overcome the defect of vane-type pneumatic rotary actuator blade " locked ", significantly promote again the full swing angle of cylinder, thereby expand the Applicable scope of vane-type pneumatic rotary actuator, made it be applicable to need the use occasion of large pendulum angle.
Disclosed is above only the application's a specific embodiment, but the application is not limited thereto.The changes that any person skilled in the art can think of, all should drop in the application's protection domain.
