Accompanying drawing explanation
In order to further illustrate the utility model, below in conjunction with accompanying drawing, further describe:
Fig. 1 is the structural representation of utility model;
Wherein: 1 support; 2 handwheels; 3 screw rods; 4 hold-down nuts; 5 sleeves; 6 displacement nuts; 7 displacement components; 8
guidingnut.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, embodiment does not form restriction of the present utility model:
Microdisplacement is realized and adjusting gear, it is characterized in that, comprise handwheel 2, screw rod 3 is connected on handwheel 2, described screw rod 3 approaches the handwheel one side screw thread hold-down nut 4 that spins, on described screw rod, go back the screw thread displacement nut 6 that spins, described displacement nut 6 displacement component that is connected, described screw rod stretches into the cavity of displacement component inside, described screw rod 3 is inconsistent with the part pitch that hold-down nut 4 and displacement nut 6 are spirally connected each other, described screw rod 3 and displacement nut 6 and displacement component are all positioned at sleeve 5, and described hold-down nut 4 is fixed on sleeve 5.The function that this place at least realizes is, because described screw rod 3 is inconsistent with the part pitch that hold-down nut 4 and displacement nut 6 are spirally connected each other, so can realize differential transmission, in the consistent situation of displacement to the right of screw rod or displacement left, the displacement mechanism that displacement nut 6 drives is realized microdisplacement.
Support 1 is arranged on test board.Make the end face of spigot nut 8 be close to the linkage assembly of test product, then rotate handwheel 2, hand wheel rotating one week drives the screw rod 3 value S1 that advances, screw rod 3 promotes displacement component 7 and stretches out value S2, thereby the linkage assembly that makes test product has the displacement of a S3, according to the test request of test product, only handwheel 2 need be turned to the test request that the position needing can reach test product.
The displacement mechanism that declines of differential screw as shown in Figure 1, the screw thread of its screw rod 3 divides two sections, and the pitch of two sections of screw threads is respectively t1 and t2, and t2>t1, and the hand of spiral is identical, and the micrometric displacement S of nut 6 is:
In formula, ψ is handwheel corner.
In order to obtain more high-precision micrometric displacement, design pitch t2 and t1, be respectively 0.75mm and 0.70mm, its difference 0.05mm, and the circular scale of handwheel 2 is divided into 50 lattice, and during hand wheel rotating one little lattice, the displacement of displacement component 7 can be as small as 1 μ m.When promoting the linkage assembly of test product with it, the piston of test product just has a corresponding stroke, so just can the response displacement value that test product is small be detected by displacement transducer.
Further, the end of described displacement component has suspension equipment.The suspension equipment at this place can suspended item or activation part, to apply displacement or to the right left; Meanwhile, also can adopt nut that dependency structure is mounted thereon, the connected mode at this place has more than one.
The pitch that described screw rod 3 and hold-down nut 4 are spirally connected is less than the pitch that itself and displacement nut 6 are spirally connected.In this place situation, handwheel forward rotation can realize start to the right.
The pitch that described screw rod 3 and hold-down nut 4 are spirally connected is greater than the pitch that itself and displacement nut 6 are spirally connected.In this place situation, handwheel forward rotation can realize start left.
The end of described displacement component also has spigot nut 8.
The pitch that described screw rod 3 and hold-down nut 4 are spirally connected with and be respectively 0.70mm and 0.75mm with the pitch that displacement nut 6 is spirally connected.Certainly, the size at this place can also be finely tuned, to adapt to the fine setting of various sizes.In demand, be not further in situation, the number of sizes at this place can be good at meeting the operation of precise displacement.On described handwheel 2, there is scale, be divided into 50 little lattice.Also comprise support 1, described handwheel 2 and sleeve 5 are all positioned on support 1.Described support below comprises installing component.Described installing component is screw.
This displacement micro-adjusting device is convenient to be required to detect and researches and develops the special mechanism of manufacture the yaw rudder servo-control mechanism response of civil aircraft B777 type, and its effect has been to the servo-controlled maintenance and inspection of yaw rudder.The practicality easy and simple to handle of this control adjusting gear, provides convenience to maintenance job personnel.
On described sleeve 5 inwalls, also have displacement transducer or pressure transducer, it connects the position that CPU can inductive displacement nut 6.
more than show and described ultimate principle of the present utility model, principal character and advantage of the present utility model.Those skilled in the art should understand the utility model and not be restricted to the described embodiments; that in above-described embodiment and instructions, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope.
