Abstract
The utility model relates to a kind of adjustable counterweight of aircraft rudder surface, is applicable to the adjustable requirement of aircraft rudder surface counterweight.Counterweight divides fixed part and adjustable part, and fixed part comprises hollow cavity and plate nut, and hollow cavity axially has groove, and plate nut is fixed on the groove edge of hollow cavity, and groove dual-side arranges groove symmetrically; Adjustable part is clump weight, the shape of clump weight is sub-tinkling of pieces of jade shape, the button-head at the two ends of clump weight is provided with two flange, clump weight is placed in the hollow cavity of fixed part, two flange on clump weight are stuck on the limit of groove, and clump weight is connected with the plate nut on fixed part by bolt.The utility model replaces traditional counter weight construction by adjustable dispersion counterweight.Compared with traditional counter weight construction, when meeting the demands, the overall center-of-gravity position of counterweight can be regulated flexibly.
Description
Technical field
The utility model relates to a kind of adjustable counterweight of aircraft rudder surface, is applicable to the adjustable requirement of aircraft rudder surface counterweight.
Background technology
The counterweight versions of conventional airplane rudder face is generally fixed, there is problems such as regulating center difficulty in debug process.
Summary of the invention
The purpose of this utility model is: provide a kind of adjustable ballasting method, can regulate the position of clump weight and quantity by actv..
The technical solution of the utility model is: counterweight divides fixed part and adjustable part, fixed part comprises hollow cavity and plate nut, hollow cavity axially has groove, and plate nut is fixed on the groove edge of hollow cavity, and groove dual-side arranges groove symmetrically; Adjustable part is clump weight, the shape of clump weight is sub-tinkling of pieces of jade shape, the button-head at the two ends of clump weight is provided with two flange, clump weight is placed in the hollow cavity of fixed part, two flange on clump weight are stuck on the limit of groove, and clump weight is connected with the plate nut on fixed part by bolt.
The width of the groove on described fixed part is greater than the width of clump weight.
Flute pitch on the spacing of the clump weight two ends button-head of described adjustable part and fixed part matches.
The quantity of described adjustable part clump weight is not more than the half of number of recesses.
The utility model has the advantages that: counter weight construction is divided into fixed part and adjustable part by the utility model, fixed part provides adjustable attachment rail for adjustable part, and adjustable part is the lumped mass block of changeable quantity.Adjustable part is connected with fixed part with the auricle for connecting.Adopt adjustable clump weight, front and back and the upper-lower position of center-of-gravity regulating can be carried out when rudder face center of gravity is debugged flexibly.Avoid the work that conventional fixed-type counterweight needs reprocessabilty.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cutaway view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is elaborated.Counterweight divides fixed part and adjustable part, and fixed part comprises hollow cavity 1 and plate nut 2, and hollow cavity axially has groove 3, and plate nut is fixed on the groove edge of hollow cavity, and groove dual-side arranges groove 4 symmetrically; Adjustable part is clump weight 5, the shape of clump weight is sub-tinkling of pieces of jade shape, the button-head at the two ends of clump weight is provided with two flange 6, clump weight is placed in the hollow cavity of fixed part, two flange on clump weight are stuck on the limit of groove, and clump weight is connected with the plate nut on fixed part by bolt.
This adjustable dispersion counterweight mainly comprises fixed part and adjustable part, its manufacturing process and method as follows:
1) fixed part is prepared: adopt sheet metal process to make half opening chute form.
2) installation of fixed part: adopt rivet to be connected on rudder face covering 7 by fixed part.
3) installation of plate nut: adopt rivet to be connected on the groove edge of fixed part by plate nut.
4) variable partition is prepared: the clump weight adopting band attachment lug, the connection of convenience and fixed part.
5) installation of adjustable part: adopt bolt to be connected on the plate nut of fixed part by adjustable part, to facilitate position and the quantity of adjustment clump weight.
Detailed description of the invention described in the utility model is not in order to limit the utility model; a just more excellent practical case of the present utility model; all make within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included in protection domain of the present utility model.
