The invention discloses a propeller structure and a rapid developing and shaping method. The propeller structure comprises propeller blades and propeller clamps. The positioning blocks are provided with matching surfaces with different inclination angles; accommodating holes for accommodating the paddles are formed in the two sides of the paddle clamp, positioning holes for mounting the positioning blocks are formed in the paddle clamp, the positioning holes are communicated with the accommodating holes, and the positioning blocks are detachably arranged in the positioning holes; a positioning rotating shaft is arranged at the end, matched with the containing hole, of the paddle clamp, and a limiting face matched with the matching face of the positioning block so as to achieve radial positioning of the positioning rotating shaft is arranged on the positioning rotating shaft. The screw pitch positioning and fastening work can be directly operated in an external field, and a special large-scale positioning tool is not needed; the performance test can be quickly carried out under different screw pitches and working conditions by opening a pair of molds to manufacture a pair of samples and then adjusting the screw pitches.

    本发明公开了一种螺旋桨构造及快速开发定型方法,包括桨叶和桨夹;还包括若干具有不同倾斜角度的配合面的定位块;所述桨夹两侧设有用于容纳所述桨叶的容纳孔,所述桨夹上设有用于安装所述定位块的定位孔,所述定位孔与所述容纳孔相连通,所述定位块可拆卸设置在所述定位孔内;所述桨夹与容纳孔配合的一端设有定位转轴,所述定位转轴上设有与所述定位块的配合面配合从而实现定位转轴的径向定位的限位面。本发明可以在外场直接操作螺距的定位与紧固工作,不用专用的大型定位工装;只需要开一副模具制作一副样品然后通过调节螺距就能快速在不同的螺距和工况条件下进行性能测试。
