In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows:
The present invention is without the need to transforming existing low-speed wind tunnel test section upper top cover, only need install detent mechanism additional in low-speed wind tunnel test section upper top cover and Low Speed Wind Tunnel wall junction and Low Speed Wind Tunnel wall correspondence position, just accurately can locate low-speed wind tunnel test section airflow direction and the low-speed wind tunnel test section upper top cover location perpendicular to the longitudinal plane of symmetry of low-speed wind tunnel test section, meet the installation positioning requirements of low-speed wind tunnel test section upper top cover;
Structure of the present invention is simple, easy processing and manufacturing, improves efficiency and the positioning precision of the installation of low-speed wind tunnel test section upper top cover, significant to raising test efficiency.
Accompanying drawing explanation
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of the adjustable locating piece of level;
Fig. 3 is the structural representation of horizontal stationary positioned block;
Fig. 4 is the structural representation of vertical adjustable locating piece;
Fig. 5 is the structural representation of vertical stationary positioned block;
Wherein: 1 is horizontal stationary positioned block, 2 is the adjustable locating pieces of level, and 3 is vertical stationary positioned blocks, and 4 is vertical adjustable locating pieces, and 5 is top covers, and 6 is test chamber walls.
Embodiment
Top cover in the present invention and test chamber wall are respectively arranged with several positioning elements, and described positioning element is made up of the stationary positioned block be arranged on top cover and the adjustable locating piece be arranged on test chamber wall; Described positioning element is divided into perpendicular positioning parts and horizontal location parts.The level of the level as Fig. 2 is adjustable locating piece and Fig. 3 can stationary positioned block composition horizontal location parts; As the vertical adjustable locating piece of Fig. 4 and the vertical stationary positioned block composition perpendicular positioning parts of Fig. 5.
As can be seen in FIG., stationary positioned block in positioning component is all arranged on top cover, in horizontal location parts, adjustable locating piece and top cover be arranged in parallel, groove on level is adjustable locating piece also with the sides aligned parallel of top cover, locating piece is fixed through groove by gib screw, by the adjustable locating piece of slide level, can adjust fixed position, and the side that level can set up locating piece is wedge structure, be used for contacting with the wedge structure of horizontal stationary positioned block.One end of horizontal stationary positioned block is fixed on top cover, and the other end stretches out, and same is arranged to wedge structure in side.The inclined-plane that wedge structure surface of contact can be arranged according to the difference of angle is also different.90 ° can be set to, that is surface of contact just with top cover place plane orthogonal.
In perpendicular positioning parts, adjustable locating piece and top cover place plane are vertical setting, and vertical adjustable locating piece and the centre of vertical stationary positioned block are protruding, and the both sides of projection are that web joint is for being fixedly connected with.The company limit that vertical adjustable locating piece protrudes is set to groove, the same with the principle of work of the adjustable locating piece of level, can by the secured adjusted of slip locating piece realization to position.The side of vertical adjustable locating piece is similarly wedge structure, is connected with vertical stationary positioned block.The inclined-plane that wedge structure surface of contact can be arranged according to the difference of angle is also different.Can be set to 90 °, that is surface of contact is just parallel with top cover place plane.
What wedge structure connect is arranged can increase contact area, increase sliding stroke, for when causing top cover to move because of vibration in process of the test, because the reason on inclined-plane effectively can reduce shift motion, and when the stroke on inclined-plane is converted to the stroke of level or upright position, the displacement of top cover is just quite little, is equal to and does not move.Wedge structure is also the innovative point of the present invention for locating thus.
As shown in Figure 1, in the present invention, in order to have better locating effect, adopt several horizontal location parts and perpendicular positioning parts, two horizontal location parts and perpendicular positioning parts are one group, perpendicular positioning parts are arranged on the centre position between two horizontal location parts, and the lozenges of two horizontal location parts to be oppositely arranged.Arrange some groups of positioning elements respectively in the both sides of top cover, the positioning element of top cover both sides will be symmetrical arranged.Such positioning precision will be very high, because vibration in process of the test, no matter be cause top cover displacement because of longitudinal judder or transverse judder, the displacement of shaking all can be made because positioning element is symmetrical arranged to cancel out each other, promote locating effect, warranty test precision.
Install and use in process repeated, first the initial makeup location of low-speed wind tunnel test section upper top cover is adjusted, then the locating piece of low-speed wind tunnel upper top cover is mounted on according to this installation site, secondly according to the installation site of stationary positioned block, installation is positioned to the adjustable locating piece being fixed on low-speed wind tunnel upper wall surface outside, carry out adjustment by the groove hole on adjustable locating piece and finally install with fixing.Namely the installation site of low-speed wind tunnel test section upper top cover is determined after installation; In later stage use procedure, first the wedge shape locating part of low-speed wind tunnel test section upper top cover is tentatively held in place on the inclined-plane of the wedge shape locating part that low-speed wind tunnel test section upper top cover is installed, along with transferring of low-speed wind tunnel test section upper top cover boom hoisting, upper top cover can be pressed into location under gravity automatically.
The present invention is not limited to aforesaid embodiment.The present invention expands to any new feature of disclosing in this manual or any combination newly, and the step of the arbitrary new method disclosed or process or any combination newly.
