Abstract
The utility model provides a balance sleeve. The balance sleeve comprises positioning steps, locking screw holes, a connecting cone and a sleeve, wherein two positioning steps are disposed on an outer wall of the sleeve; a distance between the two positioning steps is consistent with a width of a model rod head; the multiple screw holes are disposed in the left side of the sleeve; the number of the locking screw holes is consistent with the number of through holes in the model rod head; the locking screw holes are locked and connected with the through holes in the model rod head through inner hexagonal screws; and the connecting cone is disposed on the right side of the inside of the sleeve. The balance sleeve is reasonable in design, low in manufacturing cost and convenient to use, is integrally machined and molded by a forging machine, can bear a relatively large load, and has substantially improved structural strength and rigidity and prolonged service life.
Description
Technical field
The utility model belongs to model in wind tunnel support system structural design field, is specifically related to a kind of balance sleeve.
Background technology
In the model in wind tunnel support system, all need between model pole and the rod-type balance be connected by the johning knot member, the suffered strong and moment of institute of model when this johning knot member need bear wind tunnel test, comprise aerodynamic drag, lift, side force, pitching moment, rolling moment and yawing, and the coupling of multiple power and moment, force status more complicated and abominable, and this johning knot member often repeats dismounting, requires the repetitive positioning accuracy height.At present, this johning knot member generally adopts comparatively complicated composite set, this kind device repetitive positioning accuracy is poor, and composite set bulk strength and rigidity a little less than, under the design conditions of same load demand, can take bigger dimensional space, this also indirect restriction the size of the gentle model in wind tunnel in rod-type sky.In addition, composite set is then assembled for part split processing, and the processing and manufacturing cost is also higher.
Summary of the invention
For overcoming above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of balance sleeve.
The purpose of this utility model is achieved in that a kind of balance sleeve, comprise positioning step, locking screw, connect awl and sleeve, sleeve outer wall is provided with two positioning steps, the width unanimity of the distance model pole head between two positioning steps, the left side of sleeve is provided with a plurality of locking screws, the quantity of locking screw is consistent with the number of vias on the model pole head, and the locking screw is locked with the via hole on the model pole head by socket head cap screw and is connected, and the sleeve inner right side is provided with and connects awl.
The utility model is reasonable in design, and low cost of manufacture is easy to use, by forging the whole machine-shaping of material machine, has improved the structure strength and stiffness greatly; Can bear bigger load; Prolonged serviceable life.
Description of drawings
Fig. 1 is the structural representation before the use of the present utility model;
Fig. 2 is vertical view of the present utility model.
Embodiment
The invention will be further described below in conjunction with last Figure of description:
As shown in Figure 1 and Figure 2, a kind of balance sleeve, comprise positioning step 1, locking screw 2, connect awl 3 and sleeve 4, sleeve outer wall is provided with two positioning steps 1, the width unanimity of the distance model pole head between two positioning steps 1, the left side of sleeve 4 is provided with a plurality of locking screws 2, and the quantity of locking screw 2 is consistent with the number of vias on the model pole head, locking screw 2 is locked with the via hole on the model pole head by socket head cap screw and is connected, and sleeve 4 inner right side are provided with and connect awl 3.
The utility model is reasonable in design, and low cost of manufacture is easy to use, by forging the whole machine-shaping of material machine, has improved the structure strength and stiffness greatly; Can bear bigger load; Prolonged serviceable life.
