Abstract
The utility model provides a balance front cone connecting block. The balance front cone connecting block includes a model positioning straight opening, model locking screw holes, a balance tension through hole, a balance connecting cone and a basal body; the model positioning straight opening is connected with the bottom of the basal body; the model positioning straight opening is a protrusion of which the cross section is rectangle-shaped; the size of the model positioning straight opening is same with the size of a positioning straight opening on a wind tunnel test model; the bottom of the basal body is provided with a plurality of model locking screw holes; and the number of the model locking screw holes is the same with that of screw through holes distributed on the wind tunnel test model; and the balance connecting cone and the balance tension through hole are arranged inside the basal body. The balance front cone connecting block of the utility model is machined and molded wholly by a forging machine. The balance front cone connecting block has the advantages of simple structure, reasonable design, greatly improved structural strength and stiffness, heavy load-bearing capability 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 inner cone contiguous block.
Background technology
All need between model in wind tunnel and the wind tunnel test balance be connected by the johning knot member, suffered all aerodynamic force and the moment of model in wind tunnel 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 to connect, 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 model in wind tunnel, serious meeting causes because the stiffness problem of model in wind tunnel self can't design some model in wind tunnel.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 inner cone contiguous block.
The purpose of this utility model is achieved in that a kind of balance inner cone contiguous block, comprise straight mouthful of model orientation, model locking screw, balance tension via hole, balance connects awl and matrix, model orientation is connected with the bottom of matrix for straight mouthful, model orientation is the projection of square-section for straight mouthful, the consistent size that the size that model orientation is straight mouthful and the location on the model in wind tunnel are straight mouthful, the bottom of matrix is provided with a plurality of model locking screws, the screw number of vias of arranging on the quantity of model locking screw and the model in wind tunnel is consistent, is provided with in the matrix that balance connects awl and balance is strained via hole.
The utility model is simple in structure, reasonable in design, 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 structural representation of the present utility model;
Fig. 2 is left 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, a kind of balance inner cone contiguous block, comprise straight mouthful 1 of model orientation, model locking screw 2, balance tension via hole 3, balance connects awl 4 and matrix 5, straight mouthful 1 of model orientation is connected with the bottom of matrix 5, model orientation is the projection of square-section for straight mouthful 1, the consistent size that the size that model orientation is straight mouthful 1 and the location on the model in wind tunnel are straight mouthful, the bottom of matrix 5 is provided with a plurality of model locking screws 2, the screw number of vias of arranging on the quantity of model locking screw 2 and the model in wind tunnel is consistent, is provided with in the matrix 5 that balance connects awl 4 and balance is strained via hole 3.
Model orientation on the balance inner cone contiguous block is the projection of square-section for straight mouthful 1, groove is in full accord with the size of projection, purpose is the bearing accuracy that assurance repeats to install, and this model orientation is mainly born aerodynamic drag, side force and the yawing that Model Transfer is come for straight mouthful 1.
Balance inner cone contiguous block and model in wind tunnel are locked by a plurality of model locking screw 2 usefulness screws, screw number of vias and the position arranged on model locking screw 2 quantity of arranging on the balance inner cone contiguous block and position and the model in wind tunnel are in full accord, to guarantee connection accurately and reliably, this screw syndeton is mainly born aerodynamic lift, pitching moment and the rolling moment that Model Transfer is come.
Balance inner cone contiguous block is connected awl 4 with the wind tunnel test balance by balance and is connected, and passes 3 pairs of wind tunnel test balances of balance tension via hole with screw and strain.The inner cone of wind tunnel test balance is connected with balance on the balance inner cone contiguous block that awl 4 size and dimensions are in full accord, and two awls add need cooperate grinding man-hour, and the faying face after the connection should can bear bigger rolling moment to guarantee tension back faying face greater than 80%.
The utility model is simple in structure, reasonable in design, by forging the whole machine-shaping of material machine, has improved the structure strength and stiffness greatly; Can bear bigger load; Prolonged serviceable life.
